Abstract: Disclosed are embodiments of systems and methods for prioritizing mobile media player files by providing for the automated addition and/or deletion of media items for a mobile media player. In some embodiments, a statistical method may be provided for inferring which media items on a mobile media player should be deleted based on, for example, user taste data. In some embodiments, new media items may be loaded onto a user's mobile media player by creating one or more playlists from a playlist builder. The playlist(s) may be created by using user taste data. Rankings may also be created to determine an order for deletion of the media items currently on a mobile media player and/or for addition of new media items to the device.

Abstract: A method and system for programming a media delivery system (FIG. 2) in which members of the general public can produce and host programming, including non-promotional (106) and promotional media items (108), and media consumers (220) can provide direct feedback (252, 262) to the operator of the media delivery system (200) indicating the programming and advertising of most interest to them. Appropriately licensed, copyright-protected media items, and optionally promotional media items, are made available through a web-based virtual production studio (200) to users (210) who may combine them with user-provided media items to produce programming suitable for transmission over the media delivery system.

Abstract: Visualizing and exploring a music library using metadata, such as genre, sub-genre, artist, and year, is provided. Geometric shapes, such as disks or rectangles, may be divided into sectors representing genre and each sector may be further divided into sub-sectors representing artists associated with each genre. The sector's relative size generally reflects the importance of the corresponding genre within the library. Likewise, the sub-sector's relative size generally reflects the importance of the corresponding artist within the genre which may be determined by the number of media items of the artist. Marks representing each media item may be arranged and displayed within the geometric shape to reflect the mark's corresponding genre, artist, and year. In addition, each mark may reflect an attribute, such as playcount, of the media item and each sector may reflect the mean value of an attribute of all media items within the sector.

Abstract: Disclosed are embodiments of systems and methods for recommending relevant users to other users in a user community. In one implementation of such a method, two different sets of data are considered: a) music (or other items) that users have been listening to (or otherwise engaging), and b) music (or other items) recommendations that users have been given. In some embodiments, pre-computation methods allow the system to efficiently compare item sets and recommended item sets among the users in the community. Such comparisons may also comprise metrics that the system can use to figure out which users should be recommended for a given target user.

Abstract: A system and method are disclosed for unifying tags of a media user community by transferring user-supplied tags between individual user media libraries. One aspect comprises a process for identifying, within a user community, common tags associated with media items and common media items associated with tags by cross-referencing media items and corresponding tags among individual media user libraries. The system in one embodiment provides a user with a unified classification of tags, which can be used to search, navigate and organize an individual user's media library.

Abstract: Systems and methods are disclosed for identifying a new set of media items in response to an input set (or “query set”) of media items and knowledge base metrics. The system uses a knowledge base consisting of a collection of mediasets. Various metrics among media items are considered by analyzing how the media items are grouped to form the mediasets in the knowledge base. Such association or “similarity” metrics are preferably stored in a matrix form that allows the system to efficiently identify a new set of media items that complements the input set of media items.

Abstract: A system to navigate through a media item catalog using correlation metrics (FIGS. 1,2) from a knowledge base (400) of mediasets (FIG. 4, 1-7). The system uses a knowledge base consisting of a collection of mediasets. Various metrics (Metric 1-Metric m) among media items (m1 . . . ) are considered by analyzing how the media items are grouped to form the sets in the knowledge base (400). Such metrics preferably are stored in a matrix (100) that allows the system to dynamically build appropriate navigation lists (FIG. 3) from media items that a user selects (FIG. 5).
