This application is a Continuation which claims priority under 35 U.S.C. §120 to pending U.S. patent application Ser. No. 11/711,301 filed Feb. 27, 2007, entitled “SYSTEM AND METHOD FOR SELECTION OF CONTENT SOURCE UPON DEVICE POWER-ON,” and is hereby incorporated by reference in its entirety.
BACKGROUND OF THE INVENTION1. Field of the Invention
The present invention relates to displaying content on a content display system, and in particular, to determining content to display upon a power-on event in a network including multiple content sources.
2. Description of the Related Technology
Content display devices, such as a television, typically display the program that is currently being played on the channel that was being displayed when the display device was turned off. The content that is displayed when the display device is powered on may not be content that is desired. For example, if a television is tuned to the nightly news and turned off at 7 pm, and then turned on at 3 am, the displayed content will most likely not be desired content.
Some systems give a user more power-on options such as a pre-selected channel. However, these systems are typically not adaptive to what is currently available. These systems are also not designed for multiple content sources available in current integrated home or business networks.
Some systems have provisions that provide additional automation of content determination at time of power-on events. These systems may attempt to ease access to content based on a single content source by utilizing the source supplied electronic program guide (EPG) data. This also does not consider the networked environment where multiple content sources are available.
Some systems attempt to identify an individual user and have rules of content selection dependent on the user's identity. These systems may use complex methods of user identification in order to narrow down content that the individual user may be most interested in. However, mere presence of a certain user at a certain location may not mean that this user's desired content is appropriate for other viewers present at the time the display device is activated. For example, if an adult user turns on a display device in a child's bedroom, the content that is displayed may be appropriate for the adult user, but not the child that is also present. What is needed are methods and systems for determining content to be displayed at a power-on event that take into account one or more factors such as multiple content sources, display device location and time of day.
SUMMARY OF THE INVENTIONThe system, method and devices of the invention each have several aspects, no single one of which is solely responsible for its desirable attributes. Without limiting the scope of this invention as expressed by the claims which follow, its more prominent features will now be discussed briefly. After considering this discussion, and particularly after reading the section entitled “Detailed Description of Certain Embodiments” one will understand how the sample features of this invention provide advantages that include display of desirable subject matter on display devices depending on location.
One aspect is a method of determining content to display on a content display device at a power-on event. The method includes receiving content information associated with a plurality of programs that can be received and receiving location information representative of the location of a content display device in a home. The user is presented with a series of content-themed questions based on the received location information and user input in response to the questions is received. The user input is used to determine programs (shows or selections) to be displayed. This may be described as the content set-up or initialization phase.
Another aspect is a method including analyzing the content information so as to determine whether one or more of the programs satisfies a set of one or more rules, where the set of rules pertain to content appropriate for display at the location of the content display device. A power-on signal is received at the content display device; and in response to receiving the power-on signal, displaying one of the programs determined to satisfy the set of rules to the content display device. The content display device is monitored to see if a change occurs in the displayed program. Information relating to any changes in programs displayed is stored and the content selection is refined accordingly.
Certain embodiments provide a method and system for communication of multimedia content including audio and/or video information from a plurality of content display devices over an integrated home network.
The following detailed description is directed to certain sample embodiments of the invention. However, the invention can be embodied in a multitude of different ways as defined and covered by the claims. In this description, reference is made to the drawings wherein like parts are designated with like numerals throughout.
Systems and methods of improving selection of audiovisual (multimedia) programming to display on a content display device upon reception of a power-on signal at the content display device are discussed below. Multimedia programming (herein simply referred to as programming or programs) may include one or more of video data, audio data, text data, image data or any other form of media content. The programming may be in a compressed format, or an uncompressed format as well as analog or digital formats. Content to display on content display device is determined at a power-on event. In one aspect, the content is determined to satisfy a set of rules governing the type of content that is appropriate to display on the content display device. In one embodiment, the rules pertain to content appropriate for a content display device located in a specific room of a house or building. Other embodiments include rules pertaining to content appropriate for displaying on the content display device at various times of day.
Example implementations of the embodiments in an integrated multimedia content communication network will now be described.
The network 100 includes multiple sources of content including a cable connection 105 such as a set-top box, a recorded content device 110 that may include re-recorded audio and/or video, a personal computer 115 with content stored on the disk-drive or other memory, a satellite dish and/or over-the-air antenna 120, and a security system 125 including video cameras and/or audio sensors. Of course, other known content sources may also be included in the network 100.
The content sources 105 to 125 are connected to a network interface 130. The network interface provides a central location where all content sources in the network can be accessed in order to access their respective programs. The network interface 130 may be any one or a combination of an Ethernet interface, a 1394 connection interface, and/or a USB connection interface.
The network 100 also includes multiple content selector devices 135A to 135N and multiple content display devices 140A to 140N. Each of the content selector devices 135A to 135N can receive multiple programs from the content sources 105 to 125 via the network interface 130. In addition to receiving the programs, the selector devices 135A to 135N can receive content information, or metadata, about the programs available to be received on the content sources 105 to 125. In the embodiment shown, each of the content selectors 135A to 135N are configured to communicate with the content display devices 140A to 140N, respectively. The content display devices can be any of several display devices for displaying video, still images, audio or any combination thereof. The content display devices 140 are located in different rooms of a building, in the embodiment shown. For example, the content display device 135A is located in a kitchen, the content display device 135B is located in a bedroom and the content display device 135N is located in a living room. The content selector devices 135A to 135N are configured to analyze the content information received from the multiple content sources and to determine which program to display on the associated content display device 140A to 140N. Details of the methods and systems used by the content selectors 135A to 135N to determine which programs to display will be described below.
In the network 100 depicted in
The content selection element 220 analyzes content information describing the various programs that are available over the network interface 130 (see
The input element 235 is used, in some embodiments, to configure the rules that are used to determine programming appropriate for a given content display device location and/or time. The input element 235 may be a graphical user interface that a user utilizes to personalize the rules. Details of a method for selecting a set of rules are discussed below in reference to
The display control element 225 is configured to control various aspects of the content display device that the content selector device 200 communicates with. The display control element may be used to enable or disable the display device at certain times of day.
The display content monitor 250 is configured to monitor the program being displayed on the content display device 140 that is associated with the content selector device 200. The display device can be monitored to identify when a channel change command or a turn-off command is initiated by a user. Channel change commands and turn-off commands can be an indication that the content that was selected by the content selection element 220 was not content that was desired by the user. Information representing or describing the type of content being displayed after a detected channel change or turn-off event can be stored and used to modify the rules used for analyzing the content to be displayed in the future. The stored information can be communicated over the network 100 via the network interface 130 to other content selector devices. In this way, the other content selector devices can modify the rules used to select content in the future.
In some embodiments, one or more of the elements of the content selector 200 of
The data received at block 305 may be in standard formats, such as XML, which may be parsed by the content selection element 220. In some embodiments, the content selector 200 may receive the content information at block 305 from the content display device if it is connected with a media source or a network. The display control element 225 may be used to interface with the display device in these embodiments.
The method 300 continues at block 310 where content display device location information is received. The location information may be input by a user when a display device is first activated in a location. The location information may identify a type of room where the device is located such as a kitchen, bedroom, etc. The location information may also be obtained by a position determination system such as a GPS device or a proximity detector. The input element 235 of the content selector 200 may perform the functions at the block 310.
In some embodiments, an optional block 315 may be performed where a time of day is received or generated. The time of day may be used to further limit program content that may be displayed on the content display device. Details of methods for using time of day to select the rules used to determine which program to display are discussed below in reference to
After receiving the location, and optionally, the time of day information at blocks 310 and 315, the method 300 continues at block 320 where content selection rules 325 pertaining to the location of the content display device and optionally the time of day are used to analyze the content information so as to determine whether one or more of the programs satisfies the rules. Different rules may apply during different times of the day. The analysis performed at the block 320 may be a combination of rules based selection and mathematical formula where weights are assigned to various categories with higher weights being assigned to more preferred or higher priority content. The weights may be a function of time of day. Details of methods of prioritizing the content selection rules and/or mathematical formula are discussed below in reference to
An example of a mathematical formula that may be used at the block 320 comprises assigning a numerical value to a content program based on the number of times a keyword or related definition appears in the title and/or description of the content contained in the content information obtained for each program. The mathematical formula may be applied to broadcast content as well as pre-recorded content such as was previously recorded on the content recorder 230 shown in
If a program is identified at block 320 that satisfies the content selection rules, the process 300 proceeds to optional block 330 where the program that was determined at block 320 to satisfy the rules is recorded. This recorded program can be compared against other pre-recorded programs and currently broadcast programs later on when a power-on signal is received at block 335. In addition to storing the recorded content, information identifying the recorded program and the location or identity of the device in the network where the recorded program is stored may be stored and associated with the recorded program. This program identifying information can be communicated to other content selector devices in the network 100 via the network interface 130 in
At block 335, a power-on signal is received. The power-on signal may be received directly by the input device 235 of the content selector 200, or may be received at the content display device and communicated to the content selector 200 (e.g., with the display control element 225). After receiving the power-on signal at the block 335, the process 300 continues at block 340 where one of the programs determined to satisfy the content selection rules 325 is displayed on the content display device at the location received at the block 310. In one embodiment, the program displayed has the highest value as determined by the mathematical formula as discussed above. In one embodiment, the currently displayed program remains the selected program to be displayed at power-on for an amount of time (for example, 10 seconds) after the content display device is powered-off. In other words, if the content display device is turned off and turned on again within 10 seconds, the program that was being displayed is displayed again at the block 340 and not replaced by the currently highest scoring program (that may have been determined at the block 320 while the current program was being displayed). This feature is provided in case the device is accidentally turned off and the user wants to quickly go back to the program that he or she was watching. The communication element 215 and the display control element 225 may perform the functions of communicating the program data to the content display device to be displayed at the block 340.
After the program is displayed at the block 340, the content display device is monitored at block 345. The content display device is monitored to identify a change in the content being displayed (e.g., a channel change command or displaying some other recorded or broadcast content). The monitoring at the block 345 may be performed for a pre-defined amount of time after the content is displayed. If a channel/content change occurs within the pre-defined time, then information associated with the type of content that is currently being displayed can be stored and used to refine the content selection rules used for future channel/content selections. The stored information associated with the channel/content change event can be communicated over the network 100 via the network interface 130 to be used to refine the selection rules 325 used by other content selector devices 135 in the content selection analysis performed at the block 320. In addition to monitoring for a channel/content change event, if the content display device is turned off within the monitoring time period, turn-off information associated with the selected content can also be stored and communicated to other content selector devices. This turn-off information can also be used to modify the content selection rules. The display content monitor 250 can perform the functions at the block 345. It should be noted that some of the blocks of the process 300 may be combined, omitted, rearranged or any combination thereof.
After the user selects the room type at the block 405, the method 400 continues at block 410 where a series of one or more questions regarding selection of program themes are presented to the user. The themes may be a default set, or all themes listed in a prioritized order that correspond to the room type that was selected at the block 405 (e.g., sports for a bar, cooking for a kitchen, cartoons for a child's bedroom, etc.). The themes may be presented, for example, in a menu of a GUI.
As the user is presented the series of questions at the block 410, the method 400 proceeds to block 415 where the theme selection answers input by the user are received. The themes may be selected in an unlimited or default fashion or the user may also be presented with questions that narrow the programs that will satisfy his preferred content choices as discussed above. For example, the theme choice may change based on time of day. Television and/or movie ratings may be used to identify programs that are acceptable. For example, a child's bedroom may be limited to movie ratings of G only, whereas an adult's bedroom may be limited to movies rated G, PG-13, R and/or X. Critics' ratings may also be used in the selection rules. The content displayed on power-on may be limited to those programs that receive a minimum (or maximum) rating from critics, such as 3 stars out of a possible 5. The television, movie and/or critics' ratings information may be obtained at the block 310 of the method 300 from an EPG or from a data base that may be available on a personal computer such as the computer 115 in the network 100 shown in
Other questions presented to the user at the block 410 may be associated with priorities used to weight mathematical formula that are used in conjunction with the content selection rules. The answers to these priority related questions are received at block 420. The priorities may include a choice of pre-recorded content over broadcast content. A program that has been previously scheduled on a pay-per-view basis may be given a higher priority than all other programs. Certain themes may be given a higher priority weighting than other themes. In some embodiments, the priorities received at the block 420 are used in calculating the values of the mathematical formula that are used to determine the desired content to be displayed at power-on.
The process 400 continues at block 425 where content selection data obtained from any of the display and/or content selector devices on the network are imported. The imported data can include correct and incorrect content selections that were identified during the monitoring block 345 of the process 300 discussed above. The imported data can be used to modify the selection rules to result in content selections that are more closely correlated to the actual content selections made by the users. As discussed above, the real time information related to channel/content changes that were collected can be shared across the network 100 to multiple content selector devices 135 and content display devices 140 via the network interface 130.
The importing of displayed content information at the block 425 can be performed when content is being displayed or recorded, or at times when no content is being displayed, such as when the display device is off and the displayed content information was previously stored (e.g., using the memory element 210 of the content selector 200).
An example use of the content information imported at the block 425 involves a user who typically moves from a first location such as the living room to a second location such as the bedroom at a predictable or repeated time of day. The content information may be imported from the display device and/or content selector in the living room to the content selector in the bedroom and the bedroom selector device may use the imported information to select the same content depending on priority and rules. If the selection is determined to be correct at the bedroom location (based on a no-content change event), then a correlation is established for that time from a first location, the living room, to a second location, the bedroom, for a particular content selection. A stronger link may be established if a power-off to power-on occurs at 2 different locations which may have some relationship (e.g., from the living room to the bedroom).
At other times, some content is not desired on multiple content devices. An example of this is a children's pre-recorded movie. Multiple content selector devices may attempt to display the same content across multiple rooms, and the user at the second room changes the content immediately. A negative link is thus established, and/or a previous link may be removed. This behavior is not absolute, but it may be learned by the multiple devices across the network over time and multiple power-on events. These links can also be shared by multiple devices over the network 100.
The questions that are presented to the user at the block 410, and the subsequent rules that are used to determine the program to be displayed at power-on may be fine tuned for different room types through the use of focus groups and user testing to achieve the desired functionality. In some embodiments, the method 400 is performed when the content display device is first powered-on. In other embodiments, the method 400 is performed periodically or when a user selects to refine the content selection rules. It should be noted that some of the blocks of the process 400 may be combined, omitted, rearranged or any combination thereof.
Where the methods and systems discussed above are described in reference to rooms in a home, other settings may also be provided for. For example, a hotel has many different types of rooms such as a hotel lounge, a bar, an exercise room, rooms for guests, multi-room suites, etc. The hotel may also have multiple content sources including cable, satellite, over-the-air, security cameras, media servers, video-on-demand, tourist services, etc. The content selection rules and/or priorities may be selected such that the desired content is displayed on the content display devices at each location from the multiple content sources. For example, if a user is turning on a television in an individual room, the content selector may be designed to favor hotel information, or tourist services. If a display device is powered on at the hotel bar, sports themed programs may be preferred, followed by news programs. A multitude of possibilities exist that are known to skilled artisans.
Other settings including virtually any type of networked environment with multiple content sources and distinct locations can be provided for by the methods and systems discussed above. The methods and systems may also be applied in larger environments such as a mall, a stadium, or even a city. Tourist content display devices could be located at multiple points in the city and the timeliest information from multiple sources concerning events at that location could be displayed when the display device is activated by the tourist.
One disclosed embodiment is a system for determining content to display on a content display device at a power-on event, the system including means for displaying programs, first receiving means for receiving content information associated with a plurality of programs that can be received, and second receiving means for receiving location information representative of the location of the displaying means. The system further includes content selection means for analyzing the content information so as to determine whether one or more of the programs satisfies a set of one or more rules, wherein the set of rules pertain to content appropriate for display at the location of the displaying means, third receiving means for receiving a power-on signal at the displaying means, and means for communicating one of the programs determined to satisfy the set of rules to the displaying means after receiving the power-on signal. Aspects may include where the first receiving means receives content information associated with programs available from a plurality of content sources. The system may further include means for recording one of the programs determined to satisfy the set of rules before receiving the power-on signal, where the communicating means communicates the recorded program to the displaying means after receiving the power-on signal. Aspects may include where the second receiving means receives the location information from a user. With reference to
