BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to media asset groups and, more particularly, to publishing, browsing and purchasing media asset groups.

2. Description of the Related Art

A media player stores media assets, such as audio tracks, that can be played or displayed on the media player. One example of a media player is the iPod® media player, which is available from Apple Computer, Inc. of Cupertino, Calif. Often, a media player acquires its media assets from a host computer that serves to enable a user to manage media assets. In managing media assets, a user can create playlists for audio tracks. These playlists can be created at the host computer with the help of a media management application. Media assets within the playlists can then be copied to the media player. As an example, the host computer can execute a media management application to manage media assets. One example of a media management application is iTunes® produced by Apple Computer, Inc.

Typically, at a host computer, a user would create a playlist for their own personal use using a media management application. However, the grouping of the various media assets within the playlist can be useful to other users. Indeed, if the users that are performing the grouping are well-known or noteworthy, there may be particular interest in sharing such playlists. One difficulty with sharing playlists is that the media assets within the playlist can originate from a wide variety of different sources. As a result, given that a playlist does not include the songs or audio tracks themselves, the recipient of the playlist needs to have access to the identified songs or audio tracks in order to re-create the playlist on their own media management application (e.g., host computer). Another difficultly with sharing playlists is that, although on-line music stores provide users of media management application with the ability to purchase songs or albums, playlists are themselves not saleable groupings of media assets, at least not according to the recording industry.

Thus, there is a need for improved techniques to facilitate sharing and purchasing of playlists.

SUMMARY OF THE INVENTION

The invention pertains to improved techniques to create, browse, rate and/or purchase media asset groups. Media asset groups can be created by various users and published to a digital assets manager. Thereafter, the media asset groups can be finalized and made available for on-line purchase. Once the media asset groups are made available for on-line purchase, users can browse, rate and/or purchase the media asset groups at an on-line media store. One example of a media asset group (group of media items) is known as a playlist, which can pertain to a group of audio tracks.

One aspect of the invention pertains to creation of media asset groups of media assets that can be made available at an on-line media store. Another aspect of the invention is the ability to process a created media asset group to ensure appropriate availability of each of the constituent media assets of the media asset group. Still another aspect of the invention pertains to creating media asset group illustrations (e.g., mosaics) to be used with corresponding media asset groups. Yet still another aspect of the invention is the ability to enable users of an on-line media store to rate media asset groups that have been made available.

The invention can be implemented in numerous ways, including as a method, system, device, apparatus (including graphical user interface), or computer readable medium. Several embodiments of the invention are discussed below.

As a method for rating media asset groups available on an on-line media asset store, one embodiment of the invention includes at least the acts of: causing a media asset group to be displayed for a user, the media asset group pertaining to a plurality of media assets; receiving a user rating indication, the user rating indication denoting a user rating; and updating a media asset group rating in accordance with the user rating.

As a method for reviewing groups of media assets available from an on-line media asset store, the on-line media store supporting access thereto by one or more client devices via a network, one embodiment of the invention includes at least the acts of: receiving a user request, from a client device, for information concerning a particular group of media assets from a plurality of groups of media assets available on the on-line media asset store; retrieving media asset group information for the particular group of media assets from the on-line media asset store; providing the media asset group information for display on the client device, the media asset group information including a list of media items in the particular group of media assets, at least one media asset illustration, and rating selection information; receiving a user-indicated rating for the particular group of media assets, and subsequently updating a media asset group rating for the particular group of media assets in accordance with the user-indicated rating.

As a computer readable medium including at least computer program code for rating media asset groups available on an on-line media asset store, one embodiment of the invention includes at least: computer program code for causing a media asset group to be displayed for a user, the media asset group pertaining to a plurality of media assets; computer program code for receiving a user rating indication, the user rating indication denoting a user rating; and computer program code for updating a media asset group rating in accordance with the user rating.

As a computer readable medium for reviewing groups of media assets available from an on-line media asset store, the on-line media store supporting access thereto by one or more client devices via a network, one embodiment of the invention includes at least: computer program code for receiving a user request, from a client device, for information concerning a particular group of media assets from a plurality of groups of media assets available on the on-line media asset store; computer program code for retrieving media asset group information for the particular group of media assets from the on-line media asset store; computer program code for providing the media asset group information for display on the client device, the media asset group information including a list of media items in the particular group of media assets, at least one media asset illustration, and rating selection information; computer program code for receiving a user-indicated rating for the particular group of media assets, and computer program code for subsequently updating a media asset group rating for the particular group of media assets in accordance with the user-indicated rating.

DETAILED DESCRIPTION OF THE INVENTION

The invention pertains to improved techniques to create, browse, rate and/or purchase media asset groups. Media assets groups can be created by various users and published to a digital assets manager. Thereafter, the media assets groups can be finalized and made available for on-line purchase. Once the media asset groups are made available for on-line purchase, users can browse, rate and/or purchase the media asset groups at an on-line media store. One example of a media asset group (group of media items) is known as a playlist, which can pertain to a group of audio tracks. Note that the media asset group (e.g., playlist) identifies media assets that are within the media asset group, but does not include the media assets themselves.

One aspect of the invention pertains to creation of media asset groups of media assets that can be made available at an on-line media store. Another aspect of the invention is the ability to process a created media asset group to ensure appropriate availability of each of the constituent media assets of the media asset group. Still another aspect of the invention pertains to creating media asset group illustrations (e.g., mosaics) to be used with corresponding media asset groups. Yet still another aspect of the invention is the ability to enable users of an on-line media store to rate media asset groups that have been made available.

Embodiments of the invention are discussed below with reference to FIGS. 1-7. However, those skilled in the art will readily appreciate that the detailed description given herein with respect to these figures is for explanatory purposes as the invention extends beyond these limited embodiments.

FIG. 1 is a block diagram of a media purchase system 100 according to one embodiment of the invention. The media purchase system 100 includes a media store server 102 that hosts an on-line media store. The media store server 102 can off-load commerce transactions and/or delivery of purchased digital media assets to other servers, if desired. As shown in FIG. 1, the media purchase system 100 includes one or more client devices 104 for use by end users. The client devices 104 couple to a data network 106. Additionally, the media store server 102 also couples to the data network 106. In one implementation, the data network 106 can refer to one or more data networks, typically, high data-bandwidth networks, namely, wired networks, such as the Internet, Ethernet, gigabit Ethernet, and fiber optic, as well as wireless networks such as IEEE 802.11(a),(b) or (g) (WiFi), IEEE 802.16 (WiMax), and Ultra-Wide Band (UWB).

A computer program 108, typically a media management application (MMA) or other media player application, runs on the client device 104. One example of a media management application is the iTunes® application, produced by Apple Computer, Inc. of Cupertino, Calif. The client devices 104 are, in general, computing devices. As an example, the client devices 104 can be specific or general-purpose personal computers or portable media players. One example of a portable media player suitable for use with the invention is the ipod®, also produced by Apple Computer, Inc. The computer program 108 can be used by a consumer for a variety of purposes, including, but not limited to, browsing and/or purchasing media assets from the on-line media store provided by the media store server 102, creating and sharing media asset groups (e.g., playlists), organizing media assets, presenting/playing media assets, and transferring media assets between client devices 104.

The media purchase system 100 can also includes one or more client devices 110 for use by media programmers. The client devices 110 also run a computer program 112, typically a media management application (MMA) or other media player application. The computer program 112 can be the same as the computer program 108, though the computer program 112 might offer additional functionality for support of the media programmer. As an example, the media programmer uses the computer program 112 to create and share professionally design media asset groups (e.g., playlists).

The media purchase system 100 also includes a digital asset manager 114. The digital asset manager 114 is coupled to a media assets database 116. The media assets database 116 stores media asset information including metadata relating to digital media assets available for purchase at the on-line media store. The metadata can pertain to individual media assets (digital media assets) or media asset groups (digital media asset groups). Media assets can include, but are not limited to, music, video, text, and/or graphics files. In the case of music, a media asset group can be a playlist for the music. One specific example of a type of digital media asset group is referred to as an iMiX™, which is a published playlist currently available for browsing and/or purchase on Apple Computer's iTunes® Music Store. Another specific example of a type of digital media asset group is referred to as an iEssential™, which is a published playlist created by a media programmer and currently available for browsing and/or purchase on Apple Computer's iTunes® Music Store. Still another specific example of a type of digital media asset group is referred to as a Celebrity Playlist, which is a published playlist created by a celebrity and which could be made available for browsing and/or purchase on Apple Computer's iTunes® Music Store.

The media store server 102 enables the user of a particular client device 104 to purchase media assets (e.g., songs, videos, albums). Subsequently, the client device 104 can download the purchased media assets from the media store server 102, or some other server, via the data network 106. As will be understood by those familiar with data networks, other network configurations are possible. Furthermore, while the media store server 102 and the digital asset manager 114 are shown as individual and separate devices, it will be understood by those familiar with the art that other configurations are possible. As one example, each device can be implemented such that it is distributed over multiple server computers. As another example, these various servers and/or managers can be implemented by a single physical server computer.

FIG. 2A is a diagram of a media asset 200 (i.e., digital media asset) according to one embodiment of the invention. The media asset 200 shown is an audio file (i.e., song file), for example an MP3 or AAC file, although any media file type may be used.

The media asset 200 contains one or more data segments including a data segment containing media content 206, a data segment containing media information 208, and a data segment containing a media asset illustration 204. In one embodiment, the media content 206 pertains to a song, and the media information 208 is song information, which typically includes song name, artist name, and album name, as well as other publication information. Further, the media asset illustration 204 can be an image of an album cover associated with the media asset 200. In one implementation, the media asset illustration 204 is an image of a poster, photograph, or promotional material associated with the media asset 200.

FIG. 2B is a block diagram of a media asset group 250 according to one embodiment of the invention. The media asset group contains metadata, typically identifying information such as title, author/artist, etc., and pointers 252 to one or more media assets 254, for example of the type described in reference to FIG. 2A. In one example of a media asset group, the media asset group 250 contains a collection of songs gathered by an individual, along with explanatory or expository text and one or more images or illustrations.

The media asset group 250 also includes a data segment containing media asset group information (e.g., user comments) 256 and a data segment containing one or more media asset illustrations 258 associated with the media asset group 250. The media asset illustrations 258 can be associated with one or more of the media assets 252 or can be a media asset illustration associated with the media asset group 250. The media asset illustration 258 can be, for instance, a collage or mosaic of one or more of media asset illustrations associated with the media assets of the media asset group 250.

FIG. 3A a flow diagram of a client-side media asset group publication process 300 according to one embodiment of the invention. The client-side media asset group publication process 300 is performed, for example, at a client. For example, the client can refer to a media management application operating on a client computer. One example of a music management program is the iTunes® client application, produced by Apple Computer, Inc. of Cupertino, Calif. Eventually, media asset groups being processed by the client-side media asset group publication process 300 become available on an on-line media store. One example of an on-line media store is the iTunes® Music Store, operated by Apple Computer, Inc.

The client-side media asset group publication process 300 begins with creation 302 of a proposed media asset group (e.g., a playlist of songs). The proposed media asset group may be created manually by a user selecting individual media assets from a media asset source (e.g., an on-line media store or a library of music files), or generated automatically using specified criteria such as user ratings, artist name, or media genre. Next, a decision 304 determines if a publication request has been made. A publication request can be made, for example, by operating a “publish” control in a media management application (e.g., selecting a “publish” button).

If the decision 304 determines that a publication request has been made (by a submitter), then the proposed media asset group is submitted 306 to a digital media manager. The digital media manager can be, for example, the digital media manager 114 of FIG. 1. Next, a decision 308 determines if a validated media asset group has been received. Subsequently, once a validated media asset group has been received, the validated media asset group is displayed 310 for the submitter of the proposed media asset group. Typically, the validated media asset group serves to inform the submitter of the proposed media asset group which, if any, of the media assets in the proposed media asset group are available for purchase at a particular on-line media store.

Once the validated media asset group has been received, the submitter can be given the option to add or edit information (e.g., user comments) and/or illustrations (e.g., images) to be associated with the media asset group. In one embodiment, the validated media asset group includes a mosaic of media asset illustrations associated with one or more of the available media assets within the validated media asset group. Additionally, the validated media asset group can include instructions (e.g., XML or PostScript®) directing the requesting client to display the information or illustrations in a particular format.

Next, a decision 312 determines whether the validated media asset group has been accepted. The user (submitter), for example, may select an “accept” control in a media management application to indicate acceptance of the validated media asset group (e.g., selecting an “submit” or “accept” button). If the validated media asset group has been accepted, the validated media asset group is submitted 314 and the client-side media asset group publication process 300 ends. If, on the other hand, the decision 312 determines that the validated media asset group has not been accepted, then the client-side media asset group publication process 300 returns to repeat block 302 and subsequent blocks, thereby allowing the user (submitter) to create a new or modified proposed media asset group for publication.

FIG. 3B is a flow diagram of a server-side media asset group publication process 350 according to one embodiment of the invention. In one embodiment of the invention, the server-side media asset group publication process is performed using the digital asset manager of the media purchase system 100 of FIG. 1.

The server-side media asset group publication process 350 begins with a decision 352 that determines if a proposed media asset group has been received. The proposed media asset group can be a proposed media asset group as submitted 206 in FIG. 3A. Next, the media assets in the proposed media assets are identified 354. This identification 354 can be performed by the digital asset manager 114 of FIG. 1. The identification 354 of the media assets can permit some leeway allowing for typographical errors or misidentifications of the media assets in the proposed media asset group (e.g., a title misspelling or improper artist attribution). In one implementation, the identification 354 is performed with the aid of a list of common misspellings and/or misattributions.

Next, the availability of the identified media assets in the proposed media asset group is determined 356. The determination 356 can be accomplished by checking whether the identified media assets are contained within list or database containing information about media assets that are available for purchase. In one implementation, the availability can depend on a particular on-line media store where the eventual media asset group is to be made available. For example, a particular media item might be available for purchase on a United States website for an on-line media store, but not a United Kingdom website for an on-line media store. As an example, the availability can be determined by interacting with the digital asset manager 114 of FIG. 1. Note that the availability of media assets can depend on a variety of factors. For example, one or more media assets may not be available in a particular country. It is also possible that one or more media assets in the media asset group may be temporarily or permanently unavailable due to corrupted or missing digital media files.

Once the availability of the media assets has been determined 356, a validated media asset group is created 358. The validated media asset group includes at least the media assets in the proposed media asset group that are available for purchase. In one implementation, the validated media asset group does not list the media assets in the media asset group that are unavailable. In another implementation, the unavailable media assets are shown, but designated as permanently or temporarily unavailable. In still another implementation, unavailable media assets that are expected to become available in the near future are displayed along with available media assets.

Next, the validated media asset group is sent 360 to the requesting client for approval. Besides the list of media assets, the validated media asset group can include one or more images, text, and/or layout information. In one implementation, the validated media asset group is sent along with information (e.g., XML, HTML, PostScript®) directing the requesting client to display the additional text and images in a particular layout using, for example, a media management application or web browser at the requesting client. Using such-information, the requesting client can render the validated media asset group as well as render a media asset group illustration (discussed below) associated therewith. In another implementation, the media asset group illustration can be rendered at a server and delivered to the requesting client, such that the burden of rendering the media asset group illustration is off-loaded from the requesting client.

The server-side media asset group publication process 350 continues with a decision 362, which waits for acceptance of the validated media asset group. This acceptance can correspond to the acceptance as described above in reference to submission 314 operation of FIG. 3A. If the decision determines 362 that the validated media asset group has been accepted, then the validated media asset group is published 364 and the server-side media asset group publication process 350 ends. In one implementation, the publication 364 makes the media assets in the validated media asset group available for purchase from an on-line media store. For example, an on-line media store might display the media assets in the validated media asset group as a compilation or collection in the on-line media store. Additionally, the on-line media store could further display text and/or illustrations pertaining to the validated media asset group. Examples of published media asset groups can be noted as iMixes™ or iEssentials™, which are available from the iTunes® Music Store.

FIG. 4A is a flow diagram of a media asset group illustration creation process 400 according to one embodiment of the invention. The media asset illustration creation process 400 is associated with producing a media asset illustration for a media asset group. In one implementation, the media asset illustration is a mosaic that can be created by using one or more media asset illustrations from media assets in the media asset group. For example, a media asset illustration for a media asset group containing music files can be a mosaic of album cover art associated with the music files.

The media asset group illustration creation process 400 begins by obtaining 402 one or more images associated with media assets within a media asset group. For example, a media asset group may contain several music files (i.e., audio tracks), each with an associated album cover image. Typically, the media asset group will include a plurality of media assets; hence, a plurality of images are associated with the media asset group. Next, a mosaic fill pattern is determined 404. This determination can be based a wide variety of criteria, such as the number of images obtained 402, the order of the media assets within the media asset group, and/or user preferences. In one implementation, the mosaic has a grid-like arrangement of different images. For example, the different images used within the mosaic can pertain to some or all of the images obtained 402 or variations thereof. Once the mosaic fill pattern is determined 404, a mosaic is created 406 by arranging the different images according to the determined mosaic fill pattern. After the mosaic has been created 406, the media asset group illustration creation process 400 ends.

FIG. 4B is a flow diagram of a media asset group illustration creation process 450 according to another embodiment of the invention. The media asset group illustration creation process 450 can represent a more detailed embodiment than the media asset group illustration creation process 400 illustrated in FIG. 4A. The media asset illustration creation process 450 is associated with producing a media asset illustration for a media asset group. In one implementation, the media asset illustration is a mosaic that can be created by using one or more media asset illustrations from media assets in the media asset group. For example, a media asset illustration for a media asset group containing music files can be a mosaic of album cover art associated with the music files.

The media asset group illustration creation process 450 begins by obtaining 452 one or more images associated with media assets in a media asset group. For example, a media asset group may contain several music files, each with an associated album cover image. Next, image priority is determined 454. Prioritization can be based on a wide variety of criteria. For example, an image associated with more than one media asset in a media asset group can be given a higher priority than an image associated with only one media asset. As another example, image priority can be determined by looking at the order of the media assets in the media asset group, such that the first media asset in the media asset group has the highest priority.

Next, transparency is applied 456 to the image determined 454 to have the highest priority. According to one implementation, the highest priority image is processed such that it has approximately 75% transparency. However, any value, of transparency can be used. Next, a mosaic fill pattern is determined 458 based on the number of media assets in the media asset group. Alternately, a random pattern or user-generated pattern can be used to determine a mosaic fill pattern. Once the mosaic fill pattern has been determined 458, a mosaic is created 460 by arranging one or more of the obtained images over the transparent image. In one example, the transparent image is used as a background image for the mosaic, and then some or all of the obtained images are used to fill portions of the mosaic in accordance with the image priority. After the mosaic has been created 460, the media asset group illustration creation process 450 ends.

As noted above, a media asset group illustration (e.g., mosaic) can be created and used in association with a media asset group. The media asset group illustration can be created in accordance with a fill pattern, which includes a layout and a fill order. The layout identifies a plurality of regions of the media asset group illustration that are to receive individual image. The fill order is used to determine which of a plurality of images associated with media assets of the media asset group are to be used in the plurality of regions of the media asset group illustration. The images used within the media asset group illustration can be static or dynamic. For example, in the dynamic case, the images could be switch, spun or rotated periodically, with or without use of transition effects. Still further, during a creation process, a user can be permitted to edit a proposed media asset group illustration. For example, a user could drag and drop different ones of the associated images into different positions of the media asset group illustration.

Additionally, the media assets group illustration can make use of primary colors of one or more of the associated images to determine and utilize a compatible color. Additional details on determining and using compatible colors as well as creating mosaics or collages are contained in U.S. patent application Ser. No. 11/078,583, filed Mar. 11, 2005, and entitled “AUTOMATED CREATION OF MEDIA ASSET ILLUSTRATION COLLAGE.”

FIGS. 4C-4E are mosaic creation fill pattern examples according to various embodiments of the invention. These fill patterns are intended to be exemplary only. It is understood that many other fill patterns, including those incorporating other shapes (e.g., circles or hexagons), and those utilizing different relative image sizes are possible. Additionally, mosaics may be dynamic, i.e., mosaics may change over time, such as by swapping or animating images. For example, in cases where there are too many images to fit into a mosaic pattern, the various positions in these mosaic patterns may cycle through a set of images.

FIG. 4C illustrates exemplary mosaics constructed from one to four images. These mosaics can, for example, be created in accordance with the media asset group illustration creation process 400 illustrated in FIG. 4A. Part (a) shows four different images pertaining to media assets of a media asset group. These images can represent, for example, four different album covers for music files. These images are arranged left-to-right in their order of priority. Next, part (b) shows a mosaic fill pattern. Each number, 1-4, represents a position in the mosaic. Finally, part (c) shows four resulting exemplary mosaics for one, two, three and four image mosaics.

FIG. 4D illustrates exemplary mosaics constructed from five to nine images. These mosaics can, for example, be created in accordance with the media asset group illustration creation process 400 illustrated in FIG. 4A. Part (a) shows nine different images pertaining to media assets of a media asset group. These images can represent, for example, nine different album covers for music files. These images are arranged left-to-right in their order of priority. Next, part (b) shows a mosaic fill pattern. Each number, 1-9, represents a position in the mosaic. Finally, part (c) shows nine resulting exemplary mosaics for five, six, seven, eight, and nine images.

FIG. 4E illustrates exemplary mosaics constructed from five or six images. These mosaics can, for example, be created in accordance with the media asset group illustration creation process 450 illustrated in FIG. 4B. Part (a) shows six different images pertaining to media assets of a media asset group. These images can represent, for example, six different album covers for music files. These images are arranged left-to-right in their order of priority. Part (b) shows the first image with 0% transparency and with 75% transparency applied. The first image with 75% transparency is applied as a overall background image for the mosaic. Next, part (c) shows a mosaic fill pattern superimposed over the transparent image. Each number, 1-6, represents a position in the mosaic. Part (d) shows two mosaics, where images have been placed over the transparent image, demonstrating fill patterns for five and six images. Note the first mosaic of five images has no specific image in the 6^th position of the mosaic. Hence, the 6^th position merely contains that portion of the 75% transparent first image, which provides a background image, that corresponds to the 6^th position.

FIGS. 5A-5F are exemplary screen shots demonstrating a media asset group process using a media management application. These screen shots roughly correspond to steps in the client-side media asset group publication process 300 of FIG. 3A. The media asset group can be referred to as an iMix®, and the media management application can refer to iTunes®.

FIG. 5A is a screen shot of an application window 500 demonstrating a first step of a media asset group creation process. The screen shot of the application window 500 can correspond to block 302 in FIG. 3A. Shown in FIG. 5A are a media asset group 506, a media asset group title 502 (‘A-Playlist’), and a media asset group publication request control 504. The media asset group 506 is represented as a list of media assets. In this example, the media asset group 506 includes a list of ten media assets, namely, songs. The media asset group can correspond to the proposed media asset group of FIGS. 3A and 3B. A user can start the media asset group creation process by selecting the media asset group publication request control 504. Operation of the media asset group publication request control 504 can correspond with block 304 in FIG. 3A.

FIG. 5B is a screen shot of an application window 510 demonstrating a second step of a media asset group creation process. The screenshot shows a user login screen, which allows a user to access an on-line media store (e.g., media storefront).

FIG. 5C is a screen shot of an application window 520 demonstrating a third step of a media asset group creation process. In this step, a media asset group 526 is displayed. The media asset group 526 can correspond to the validated media asset group of FIG. 3A and 3B. More particularly, the displaying of the media asset group within the application window 520 can correspond to operation 308 of FIG. 3A. In this example, the media asset group 526 includes a list of the same ten media assets, namely, songs, as the media asset group 506 in FIG. 5A. In this particular example, all ten media assets from the media asset group 506 are available from the on-line media store; hence, the media asset group 526 includes the same ten media assets. However, the media asset group 526 can include less than the same ten media assets as the media asset group when one or more of the ten media assets are not available from the on-line media store. A mosaic 528 is also depicted in the application window 520. In the particular mosaic 528 illustrated in FIG. 5C, the media asset group only includes two associated images (i.e., album covers). Hence, the mosaic 528 includes the first and second images in two positions of the grid, and a largely translucent first image as a background in the remaining two positions. Additionally, text boxes 522 and 524 are shown. The text box 522 allows a user to enter a title for the media asset group. The text box 524 allows a user to enter descriptive information to describe the media asset group. If the user is satisfied with the media asset group and has entered a title and/or descriptive information, the user may operate a media asset group approval control 530. For example, the media asset group approval control 530 can be a “Publish” button that a user can select. Operation of the media asset group approval control 530 can correspond with block 312 of FIG. 3A.

FIG. 5D is a screen shot of an application window 520′ demonstrating a third step of a media asset group creation process. The application window 520′ is generally the same as the application window 520 illustrated in FIG. 5C. However, in FIG. 5D, the mosaic 528′ includes two associated images (i.e., album covers). Hence, the mosaic 528 includes the first and second images in two positions of the grid, and a largely translucent first image as a background in the remaining two positions.

FIG. 5E is a screen shot of an application window 530 demonstrating a fourth step of a media asset group creation process. At this point, the media asset group has been published and has become available at an on-line media store for consumers to browse. This screen shot serves as a confirmation to a user that their media asset group has been published and is available on the on-line media store. The screen shot also informs the user how the media asset will be illustrated on the on-line media store. Additionally, the screen shot includes a rating area 532 that allows a user (creator or browser) to rate the associated media asset group. In this example, the user selects a rating (e.g., via a radio button) and then operates a rating control 534 (e.g., “Submit” button). Hence, even the user who created the media asset group is able to rate his or her own media asset group.

FIG. 5F is a screen shot of an application window 540 demonstrating a fifth step of a media asset group creation process. The application window 540 is an example of an application window that is visible to a consumer who visits an on-line media store. The application window 540 displays a published media asset group. The published media assets group was created in accordance with the screen shots illustrated in FIGS. 5A-5E. Any consumer (user) of the on-line media store, which has the media asset group available, can view the media asset group and select any or all the songs in the group for purchase by operating purchase controls 542 or 544. The purchase control 542 is labeled “Add All Songs”, indicating that a user of the on-line media store may add all songs in the media asset group to a virtual shopping cart (for subsequent purchase). The purchase controls 544 are labeled “Add Song” and allow a user to individually add songs to the virtual shopping cart (for subsequent purchase). Alternately, the purchase controls 542 and 544 can be labeled “Buy” rather than “Add”, allowing single-click purchases. It should be noted that regardless of whether a single-click or virtual shopping cart is used, the media assets (songs) are individually purchased by the system. For example, the operation (e.g., selection) of the purchase control 542 would initiate the separate purchase of each of the ten individual songs of the media asset group display in the application window 540. In addition, the user can rate the media asset group by making a rating selection and operating a rating control 546.

According to one embodiment of the invention, a rating system incorporating a decay factor is employed. The decay factor keeps average user ratings for publicly viewable media access groups from becoming stale over time.

For instance, as described above in FIGS. 5E and 5F, a user of an online media store may rate a media asset group. One rating system in common use employs a rating system of one to five stars, with a one star indicating that the user strongly dislikes the displayed media asset group and a five star rating indicating that the user strongly likes the displayed media asset group. However, due to the nature of public opinion, a group of media assets may be popular for only a short time. Conversely, a media asset group might become more popular over time as one or more of the media assets in the group is discovered by the public. Under conventional ratings schemes, old ratings are counted the same as newer ratings, leading to ratings that do not accurately reflect the current opinion of the rating public. According to one embodiment of the invention, a decay factor is used to minimize the effect of old or “stale” ratings.

FIG. 6A is a flow diagram of a rating process 600 according to one embodiment of the invention. The rating process 600 begins by displaying 602 a media asset group. Typically, the media asset group would be displayed 602 with a media asset group rating associated with the media asset group. For example, the on-line media store can present the media asset group and its rating to the user. In one implementation, a user of the on-line media store can participate in rating the media asset group. Hence, following the display 602 of the media asset group, a decision 604 receives user rating for the media asset group. For example, as shown in FIGS. 5E and 5F, a user (viewer) of the media asset group can enter a rating. Once the decision 604 determines that a user rating is received, an media asset group rating is updated 606. Here, the media asset group rating is updated 606 according to the user rating that has been received. The updated media asset group rating is then stored and used subsequently, such as, when displaying the associated media asset group. In one implementation, the updated media asset group rating represents an average user rating for the media asset group. In another implementation the updated media asset group rating can be a decayed average rating.

The on-line media store can also make use of the media asset group rating when users browse thought large numbers of media assets groups. For example, a use of the on-line music store could browse, search or sort media asset groups based on ratings.

FIG. 6B illustrated a screen shot of a media asset groups being listed on an on-line media store. In this example, the screen shot pertains to an application window having iMixes displayed along with their current user rating. Note that the media asset group ratings 608 are also depicted proximate to their associated media asset groups. Mini-mosaics 610 and 612 are also depicted in the application window shown in FIG. 6B. For example, the mini-mosaics 610 and 612 can be generated as a regular mosaic for a media asset group with limits on the number of images that are included. In this example, the mini-mosaics 610 and 612 are limited to four images, arranged in a 2×2 grid. In the particular mini-mosaic 610 illustrated in FIG. 6B, the media asset group only includes two associated images (i.e., album covers). Hence, the mini-mosaic 610 includes the first and second images in two positions of the grid, and a largely translucent first image as a background in the remaining two positions. In the mosaic 612, the media asset group might include two or more associated images, but not more than four images would be presented in the 2×2 grid. Typically, the mini-mosaics 610 and 612 would be displayed when the overall size of the mosaic to be displayed is limited, even though the regular mosaic would include more images, such provides a better illustration of the mosaic (less images presented) given the confined size.

In another implementation the updated media asset group rating can be a decayed average rating. Here, the update 606 of the update process 600 to the media asset group rating can be calculated using a decayed average rating. The decayed average rating calculation can utilize, for example, an exponential decay function, updated daily, hourly, or continuously.

For instance, old ratings can decay exponentially, according to an exponential decay equation, similar to a half-life calculation. In a half-life calculation, a valued is halved over specific period of time. As subsequent time periods pass, the value is halved repeatedly. Thus, taking a value of 100 and assigning a half life of one day, the value will be 50 on day two, 25 on day three, 12.5 on day four, etc. Using this concept, and applying basic mathematical principles, a weighted average rating can be calculated such that any particular rating has one half of its original weight after 30 days, one quarter of its original weight after 60 days, etc. In general, for m ratings, each having v_n votes, with each rating r_n being t_n days old, and a decay factor of D, the average weighted rating R_w is: $\begin{array}{cc}{R}_w=\frac{\sum _{n=1}^m{r}_n·v_n·D^{t_m-t_n}}{\sum _{n=1}^m{v}_n·D^{t_n}}& \left(1\right)\end{array}$

If it is desired that a rating decay such that it is has one-half of its initial significance (weight) after 30 days, the decay factor D is: $\begin{array}{cc}D=\sqrt[30]{\frac{1}{2}}\cong 0.97716{\mathrm{day}}^{-1}& \left(2\right)\end{array}$

FIG. 6C is a visual representation of an exemplary a decayed average calculation applying equations (1) and (2) to a series of ratings varying in age from 0 to 120 days. For simplicity, only five days of ratings are shown, and no other votes are shown during the remainder of the time period. In this particular example, 20 votes are cast on each day. On day t₁, 20 votes are cast, having an average rating of five stars. On day t₂, 30 days later, 20 votes are cast, averaging four stars. Similarly, every 30 days, 20 votes are cast on days t₃, t₄ and t₅. The average ratings for each day are three, two, and one stars, respectively. This is meant to simulate a decrease in ratings over time, from an average rating of five stars at t₁ to a average rating of one star on day t₅. Using the above equations, at time t₅, 120 days after time t₁, the decayed average rating is 1.83 stars. For comparison, a non-weighted average rating, R, calculated over the same time period, using the formula: $\begin{array}{cc}R=\frac{\sum _{n=1}^m{r}_n·v_n}{\sum _{x=1}^y{v}_x}& \left(3\right)\end{array}$
yields an average rating of 3.00 stars. It can be seen that, in the weighted rating, the newer ratings have more weight, which is believed to more accurately reflect the current public opinion of the media asset group. It is understood that the above is for exemplary purposes only and that a myriad of other decayed rating schemes may be used.
