Description:
CROSS REFERENCE TO RELATED APPLICATIONS 
     This application is a continuation of U.S. Pat. No. 9,311,364, filed Apr. 20, 2015, entitled “System And Method For Generating Dynamically Filtered Content Results, Including For Audio And/Or Video Channels”, which is a continuation of U.S. Pat. No. 9,105,147, filed Dec. 20, 2007, entitled “System And Method For Generating Dynamically Filtered Content Results, Including For Audio And/Or Video Channels”, the disclosures of which are hereby incorporated herein by reference in their entirety. 
    
    
     FIELD OF THE INVENTION 
     The present invention relates to a system and method for generating dynamically filtered content results, including for audio and/or video channels. A user can iteratively select content of interest among the filtered content results to receive suggestions on additional filtering characteristics. The additional filtering characteristics can then be used to redefine the filtering characteristics to provide content results focused on content having characteristics similar to the user&#39;s selected content result of interest. 
     BACKGROUND 
     In recent years, there has been enormous increase in the amount of digital content available online. As a result, the amount of content downloaded by users has increased. This content includes audio and video content. For example, Apple® iTunes® enables users to legally purchase and download music to personal music devices. Video services exist that allow users to access and download video media. Due to the large amount of content available, searching and filtering technologies have emerged as an important enabler to assist users in navigating large amounts of content to produce and manage subsets of available content. These technologies are desired to allow users to filter content according to the user&#39;s desires or interests. 
     Current filtering technologies can be used to generate content results according to user-defined characteristics or criteria. However, these filtering technologies may be inefficient in sufficiently allowing a user to focus the content results to the user&#39;s particular interests or goals. For example, a user may select certain genre tags to generate song results meeting the desired genre. If the results are not sufficiently narrowed to the user&#39;s desires or interests, the user may have to change or replace the genre tags to produce new results. The user may have to guess which tag changes or replacements should be made to achieve focused results with no guarantee that more focused results will be produced. The user may have to provide several iterations of different filtering settings or characteristics to finally reach a result set that is sufficiently narrowed to the user&#39;s interests. As one can imagine, this can be time consuming and possibly frustrating to a user, especially if the iterations do not provide sufficiently focused results. 
     Further, the user may not be aware of all available filter settings that can be used to filter content to the desired results. Unknown filter settings may be the ones that would successfully produce the desired focused results. For example, in the iTunes® music classification system, there are over 230 different genre and sub-genre music types. Many users are only familiar with the most popular genre types. However, the most popular types often produce the greatest number of search results and thus provide the least focus. Less commonly known genres may be available to produce the desired focused results. 
     Thus, a need exists for providing a user the ability to more effectively focus content results to the user&#39;s particular desires or interests. The user may be unfamiliar with all available filtering characteristics associated with the content at issue. Thus, the user may not be able to efficiently focus content results without additional suggestions or assistance. 
     SUMMARY 
     Embodiments described include systems and methods for allowing a user to more effectively generate focused content results, including but limited to audio and/or video content results. Content is initially filtered to generate results in response to initial filtering characteristics or settings. The content results are then provided to a user for review. Once the user finds and selects a content result of particular interest, additional filtering characteristics associated with the selected result are provided to the user as suggestions to include as updates to the filtering settings. The suggested filtering characteristics are characteristics that were previously unaccounted for in the filtering settings to produce the results. The updated filter settings can then be used to generate new content results. In this manner, the regeneration of content results is more likely to produce highly relevant and focused results. This is because the results are used to affect the filtering itself. The additional filtering characteristics suggested to the user are characteristics of results deemed relevant by the user, as opposed to traditional filtering engines that only produce results in one direction—from settings to results. With each new generation of content results, additional and previously unaccounted for filtering characteristics of selected results can be continued to be provided to the user. The user can continue to select these additional filtering characteristics to generate new content results in an iterative and dynamic manner until the results are sufficiently focused to the user&#39;s desires. It is possible that after a certain number of iterations, the user&#39;s selection of results will not provide new previously unaccounted for filtering characteristics. This may also provide the user some degree of comfort that the content results are sufficiently focused. 
     In one embodiment of the present invention, the content is audio and/or video media. In the context of media, the filter settings or characteristics can be provided in the form of tuner settings. A tuner is provided to generate content results based on the tuner settings. The tuner settings form media channels when used by the tuner to filter content and generate content results. Importance levels may be assigned to the tuner settings to control the dominance of particular settings in tuning. The tuner settings may also be predefined preferences of the user or other preferences assigned by a system. For example, the tuner settings may be based on a scoring system, wherein the scores are determined according to predefined preferences, including those of a user. As the tuner settings are adjusted, media content results are produced. The tuner settings can be stored to create a media channel for later retrieval and content generation. The media channels can be given custom names by the users for recognition and later retrieval for tuning. 
     The tuner settings can also be provided in the form of one or more tags. The tuner generates content results based on content matching the tags. The tuner settings can include multiple tags of the same type in a tag grouping. A tag grouping is a container that can hold one or more tags of the same type. For example, one type of tag group is “genre.” With the genre tag group, a user can deposit one or more genre tags of interest to be used in filtering to produce content results. The tags within a tag grouping can be assigned different levels of importance in filtering. For example, a “rock” tag within a genre tag grouping can be assigned an importance level of 8 out of 10, while a “metal” tag in the same genre tag grouping can be assigned an importance level of 6 out of 10. In this instance, the tuner will focus the content results more towards “rock” genre than “metal” genre. 
     In addition to or in lieu of the system suggesting additional characteristics associated with a result of interest selected by the user from among the content results, additional filtering characteristics can also provided to the user for inclusion in the tuner settings that are related to the characteristics of the user-selected result. These additional related characteristics may not be accounted for in the filter settings. The system may have stored characteristics that are deemed relevant to those included in the user&#39;s selected result. For example, a user-selected result may include a “hard rock” genre tag. In response, the system may suggest “rock” genre as an additional filtering characteristic for a result having a “hard rock” tag. In this example, the system has stored “hard rock” genre as being relevant to “rock” genre.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     The embodiments set forth below represent the necessary information to enable those skilled in the art to practice the invention and illustrate the best mode of practicing the invention. Upon reading the following description in light of the accompanying drawing figures, those skilled in the art will understand the concepts of the invention and will recognize applications of these concepts not particularly addressed herein. It should be understood that these concepts and applications fall within the scope of the disclosure and the accompanying claims. 
     Embodiments of the present invention include systems and methods for allowing a user to more effectively generate focused content results, including but not limited to audio and/or video content results. Content is initially filtered to generate results in response to initial filtering characteristics or settings. The content results are then provided to a user for review. Once the user finds and selects a content result of particular interest, additional filtering characteristics associated with the selected result are provided to the user as suggestions to include as updates to the filtering settings. The suggested filtering characteristics are characteristics that were previously unaccounted for in the filtering settings to produce the results. The updated filter settings can then be used to generate new content results. In this manner, the regeneration of content results is more likely to produce highly relevant and focused results. This is because the results are used to affect the filtering itself. The additional filtering characteristics suggested to the user are characteristics of results deemed relevant by the user, as opposed to traditional filtering engines that only produce results in one direction—from settings to results. With each new generation of content results, additional and previously unaccounted for filtering characteristics of selected results can be continued to be provided to the user. The user can continue to select these additional filtering characteristics to generate new content results in an iterative and dynamic manner until the results are sufficiently focused to the user&#39;s desires. It is possible that after a certain number of iterations, the user&#39;s selection of results will not provide new previously unaccounted for filtering characteristics. This may also provide the user some degree of comfort that the content results are sufficiently focused. 
     In one embodiment of the present invention, the content is audio and/or video media. Filter settings or characteristics are provided in the form of tuner settings. Importance levels or weightings may be assigned to the settings. The tuner settings may also be predefined preferences of the user or other preferences assigned by a system. For example, the tuner settings may be based on a scoring system, wherein the scores are determined according to predefined preferences, including those of a user. As the tuner settings are adjusted, media content results are produced. The tuner settings form media channels. The media channels can be stored for later retrieval and content generation by storing the tuner settings. The media channels can be given custom names by the users for recognition and later retrieval for tuning. 
     In this regard,  FIG. 1  is a flowchart illustrating the filtering process according to one embodiment of the present invention. The exemplary steps in  FIG. 1  will be discussed in conjunction with user displays in  FIGS. 2-7B , which may execute on a client device to provide the content results to a user in response to filtering content. In this embodiment, the content being filtered is audio and/or video media. Filtering in this context is also known as tuning. A tuner may be provided to execute the filter. Filter settings or characteristics in the form of tuner settings are used by the tuner to filter content and provide filtered content results. The tuner settings may be predefined preferences of the user or other preferences assigned by a system. For example, the tuner settings may be based on a scoring system, wherein the scores are determined according to predefined preferences, including those of a user. As the tuner settings are adjusted, the tuning content results are regenerated. The tuner settings form media channels. Different channels may be established and selected by a user wherein each channel has associated tuner settings. Thus, when a particular channel is selected, the tuner settings stored for the channel will be recalled by the tuner to generate the content results. 
     Turning to  FIG. 1 , the exemplary process of tuning audio and/or video media starts by applying the current tuner settings for the selected channel to produce the tuning results (step  10 ). Next, the content results are provided to the user on a user client so that the user can browse or select from among the results (step  12 ).  FIG. 2  illustrates an example of a display  100  that may be displayed by a user client to provide content results to a user. In this example, the content is displayed in a display window  102 . The name of a selected channel  104  may be displayed in the display window  102  to show the user which channel is currently being tuned. The content results  106  may be visually displayed to the user, whereby the results are a function of content generated when the tuner settings for the selected channel are applied (e.g. step  10  of  FIG. 1 ). In this example, the content results  106  are album or song media recommendations made to the user from other peer users in a media recommendation system. Such a system is described in co-pending and commonly assigned application Ser. No. 11/484,130 entitled “P2P NETWORK FOR PROVIDING REAL TIME MEDIA RECOMMENDATIONS,” which is incorporated herein by reference in its entirety. 
     In the example illustrated in  FIG. 2 , the tuner settings in this example are to provide the results  106  in the order of recommendation scores. A scoring system previously scored the recommendations according to preferences or settings. In this example, the results  106  are provided in the form of icons. The song having the highest recommendation score is displayed at the top left icon of the results  106 . The next highest scoring recommendation is displayed next in numerically descending order, from left to right, and top to bottom. If more recommendations result from the tuner settings than can be displayed on the display  100  at one time, a paging scroll bar  107  may be provided to allow the user to traverse between different pages to display all the content results  106 . Also note that in the spirit of providing a simplified drawing example, the results  106  illustrated in  FIG. 2  and later illustrations include duplicate icons. However in practice, each result  106  would typically be unique. 
     In this example, the filter characteristics or tuner settings associated with the results  106  are tags that are displayed in tag groupings  108 A- 108 E. The tag groupings  108  are designed to hold tags of the same type. For example, the genre tag grouping  108 A holds genre type tags. The tag groupings  108  are filled with tags that represent the tags associated with the results  106  in this example. Thus initially, the tag groupings  108  are part of the tuner settings, but they were not set directly by the user in this example. However, the user can adjust the tags in the tag groupings  108  to adjust the tuner settings. In response, the content results  106  will be regenerated by the tuner according to the adjusted tuner settings. Further, the user can adjust the tag groupings  108  themselves to control whether any tags of a certain tag type will be included in the tuner settings, and if so, to what extent. 
     In the example of  FIG. 2 , the dominance or level of importance of the tag groupings  108  are provided according to their visual size. The level of importance can be adjusted by the user. For example, the “genre” tag grouping  108 A is larger in size than the “artist” tag grouping  108 B. This means that “genre” tags are deemed to play a higher level of importance by the tuner to produce results  106  than the “artist.” Likewise, the tags within a tag grouping  108  can also be sized to control the relative level of importance among other tags.  FIGS. 3A and 3B  illustrate this concept by example. As illustrated in  FIG. 3A , the user has selected the “hip-hop” tag  110  within the “genre” tag grouping  108 A. Once selected, a sizing ellipse  112  is displayed for the “hip-hop” tag  110  with the current level of importance  113  display. Sizing arrows  114  are also displayed that allow the user to click and drag in the desired direction to expand or shrink the size of the tag  110  to change its level of importance  113 . In this example, the level of importance for the “hip-hop” tag  110  is ‘8’ out of a maximum of ‘ 10 .’ If the level of importance is changed by the user by resizing the sizing ellipse  112 , the level of importance  113  will also be updated and displayed in kind in the sizing ellipse  112 . Selecting a tag grouping  108  may also cause a pop-up window  116  to be displayed to allow the user to add other tags  118  to the tag grouping  108  to be included in the tuner settings. More information about the ability to assign tags to tag groupings  108  and resizing tag groupings and/or the tags within tag groupings to control relative levels of importance in filtering content is described in co-pending and commonly assigned application Ser. No. 11/955,534, filed on Dec. 13, 2007 and entitled “RESIZING TAG REPRESENTATIONS OR TAG GROUP REPRESENTATIONS TO CONTROL RELATIVE IMPORTANCE,” which is incorporated herein by reference in its entirety. The tags assigned to a tag grouping as well as their assigned level of importance may be stored in a tag table  119  as part of the tuner settings. 
     After the content results  106  are displayed to the user (step  12  in  FIG. 1 ), the system waits for a selection from the user. The user may select any item of interest among the content results  106  for play or further inspection (step  14 ). The user can quickly expose more detail about a particular content result  106  by moving a mouse cursor over the icon of the desired result. If the user desires to select a particular content result  106 , the user can then click on the icon representing the desired result  106 .  FIG. 4  illustrates a user display  100  showing an exemplary result  106  selected by the user. In this example, the user has selected the highest scoring song recommendation by clicking at the top left of the results on “Forgotten,” by “Linkin Park.” In response, a results window  120  is generated to show the user more information about the selection. The album cover  122 , play controls  124 , and other characteristic information about the result  126  are visually displayed to the user. Some characteristic information about the selected result is already included in the tuner settings. These characteristics of the selection are highlighted in both the results window  120  and the tag groupings  108 . For example, the selection illustrated in  FIG. 2  is of “alternative” genre  132 , was released in the “2000&#39;s” decade  133 , and was recommended by “Abraham”  134 . Highlighting may take the form of a different text color, font, text size, or other visually distinct manner. This provides a convenient visual display to the user of which tuner settings used by the tuner were met by the selected result. 
     In addition to informing the user of characteristics of the selected result that are included in the tuner settings, any additional characteristics associated with the selected result that are not included in current tuner settings are also highlighted to the user within the characteristic information  126 . These are also called unaccounted characteristics, or unaccounted tags in this example. In this example of  FIG. 4 , the artist name “Linkin Park”  130 A and the “punk” genre are highlighted as additional characteristics not presently included in the tuner settings. Thus, if the user wants to further focus the content results  106  to results more closely focused on the characteristics to the selected result, the user can select any of the additional characteristics to be added to the tuner settings (step  16  of  FIG. 1 ). The system will add the unaccounted characteristics to the tuner settings (step  18  of  FIG. 1 ), and the tuner will automatically generate updated results  106  based on the updated tuner settings taking into account the previously unaccounted characteristics selected by the user. In this manner, the user can easily start focusing the results  106  to those more similar to the characteristics of their selected results of interest. Thus, the present invention allows the user to adjust the tuner settings in an iterative manner based on characteristics of content results of interest to the user. This will effectively focus the results  106  to those highly relevant to the user&#39;s desires or interest. This is opposed to filtering technologies where the user adjusts the tuner settings not based on characteristics of relevant results, but on other factors. Thus, these other filtering technologies are only as effective as the user&#39;s knowledge and skill of the possible characteristics available for filtering. In contrast, the present invention also provides suggestions to the user for additional filtering characteristics based on results the user has deemed relevant to their interests. 
       FIG. 5  illustrates an example of the user display  100  after the user has selected previously unaccounted characteristics to be included in the tuner settings causing the tuner to regenerate content results  106  (steps  16  and  18  in  FIG. 1 ). Note that the tag groupings  108  now include the previously unaccounted and user-selected tags of “punk” genre  138  and artist of “Linkin Park”  140 . Because these tags are now part of the tuner settings, they are likewise highlighted in the tag groupings  108  as being accounted for and relevant characteristics in the current tuner settings. Once the unaccounted tags are added to the tag groupings  108 , the user can resize those tags as well as others, as previously described, to adjust their level of importance in use by the tuner to generate results  106 . A default level of importance may be provided until the user resizes tags and/or tag groupings. 
     The process continues by the tuner generating content results  106  based on the user&#39;s selection of relevant results  106  and providing adjustments to the tuner settings. These adjustments can include both accounted and unaccounted characteristics in the tuner settings. The user repeats this process in an iterative manner, if desired, until the user is satisfied that the content results  106  are sufficiently focused. If desired, the user can store the tuner settings under a new channel at any time during the iterations (decision  20  in  FIG. 1 ). If a new channel is created, the current tuner settings are stored under the new channel (step  22  in  FIG. 1 ). An example of this is illustrated in  FIG. 6 , wherein the new channel “New Alt Channel” has been created. In this manner, the user can recall stored tuner settings assigned to the channel that produced the desired content results  106 . Once a new channel is created, the process repeats by providing content results  106  according to the tuner settings as the initial results  106 . Thus, no tags in the tag groupings  108  will be highlighted for a newly selected channel until a particular result  106  is selected by the user. 
     In another embodiment, the present invention can also facilitate focusing content results  106  by providing the user additional filtering characteristics that are not assigned to the user-selected content result, but instead are related to the selected content result. This allows the user more options to focus content results based on related interests or goals. In this embodiment, the system provides the related additional characteristics for the user as a measure of assistance instead of the user having to be solely familiar with related characteristics that may be included in updated filter settings. 
     The additional related filtering characteristics may not be accounted for in either the tuner settings or in the characteristics of the user-selected content result. The user is then free to select any of these additional related filtering characteristics to be included in the tuner settings to have the tuner produce updated content results  106 .  FIG. 7A  illustrates this by example. In this example, the user has selected the song “Forgotten” by “Linkin Park” from the content results  106 . However, in this embodiment, the additional related characteristics that are not included in the selected result, but are related to it, are displayed for possible selection. In this example, several different genre types  142  are displayed in an additional related characteristic ellipse  144  for possible selection that are not “alternative” and “punk” genres, but may be closely related to these genre types. The system may have pre-defined settings indicating which additional related characteristics or tags are to be provided and displayed to the user in response to given characteristics of a user-selected content result  106 . A table may be provided to store these additional related characteristics like the additional related genre table  145  illustrated in  FIG. 7B . In this example, other genres  142  are assigned as being relevant to “punk” genre, with a level of importance or relevance assigned to each. This level of importance controls the sizing of the additional related characteristics when displayed in the additional related characteristic ellipse  144 . 
       FIG. 8  illustrates an alternative user display  150  for displaying content results to a user. In this example, the content results  106 ′ are provided in list form as opposed to icons. Other characteristics  152  of the results  106 ′ may be displayed in the list. In this example, a score  154  is also associated with each of the results  106 ′. This score  154  may be used to control the ordering of the initial results set by the tuner in this example. The scoring may be based on any settings or algorithm, including settings based on the user&#39;s preferences. 
       FIG. 9  illustrates a system diagram of a content delivery and sharing system  170  that may be employed by the present invention to access and filter content. A central server  172  may be provided that provides access to content and other content related services, such as content flow management, to user devices  174  over a network  176 . The network  176  may be a wide area network, a local area network, a wired or wireless network, or any other type of network, including but not limited to the Internet. The central server  172  may facilitate providing content services to user devices  174  via a server component  178  that executes to handle requests and provide responses. This also enables users to access and share content in the system  170  and with other peer user devices  174 A- 174 N. The central server  172  may have accessible content stored in a database  182  or may obtain the content from other services, such as subscription-based services  194 . 
     The central server  172  may require the user to have an established user account  180  stored in the database  182  to access content-based services from the central server  172 . To establish a user account, users may direct their user device  174  to contact the central server  172 , and namely the server component  178  within the central server  172 . The server component  178  may store user account and associated information in a record of user accounts  180  in the database  182  within or accessible to the central server  172 . 
     The user devices  174  may contain a media player  184  to allow a user to play media content and content results, including songs and/or video presentations for example. The user device  174  may also contain a tuner  190  to provide the results  106 ,  106 ′ to a user at the user device  174  as previously described. The user device  174  may also contain tuner settings  192  locally to be used by the tuner  190  to provide content results to the user. Alternatively, the tuner settings may be stored remotely, such as at the central server  172  under the user&#39;s account, or elsewhere that is network accessible. The tuner settings  192  may be predefined user preferences or settings, or may be any other type of settings or algorithms for allowing the tuner  190  to filter and provide content results. 
     The user device  174  may also have media content stored locally in a user&#39;s media collection  186 . The tuner  190  may access the media collection  186  to provide content results. If the desired media content is not stored locally, the tuner  190  may also be adapted to access other systems to obtain desired media content. In this regard, the user device  174  may request media content from the subscription service  194 , or from the central server  172 . 
     Further, in order to access media-based services from the central server  172 , users may be required to download a client application  188  to their user device  174  from the central server  172 . The client application  188  provides software to allow the user devices  174  to communicate with the central server  172  to access media-based services and related information. For example, a user device  174  may contact the central server  172 , via the client application  188 , to request certain media content. The central server  172  may provide the requested media content from its database  182  if present, or may access an outside service, such as the subscription service  194  for example, to access the requested media content. 
     The client application  188  may also facilitate the user devices  174  sending and receiving media recommendations to and from other peer user devices  174  in the system  170  as described in application Ser. No. 11/484,130, previously referenced above. A user may desire to recommend a given media content to a friend. In this instance, the user, acting as a recommender, instructs their user device  174  to send a recommendation for the desired media content to a recipient user&#39;s device  174 . This instruction may be performed by the recommender user manually or automatically as a result of the recommender playing a given media content. The recommender user may have a pre-defined list of friends that will be sent recommendations for media content once played by the recommender user. In either case, the media recommendation is sent over the network  176  to the central server  172 . The central server  172  intercepts the media recommendations and forwards it to the recipient&#39;s user device  174 . There, the recipient&#39;s user device  174  may place the media recommendation in a media queue, which may be a playlist for example, so that the recipient user&#39;s device  174  can access, display, and/or play the recommended media content. The media queue may contain an ordered list of media content scheduled to be played by the user device  174 . The order of placement of the received media recommendation in the media queue may be controlled by a scoring algorithm. The scoring algorithm may be controlled or influenced by the tuner settings  192 . The tuner settings  192  may include preferences based on media attributes, or may be based on other information including the identity of the recommender, as examples.
