## Background
TECHNICAL FIELD
Particular embodiments generally relate to media processing.
BACKGROUND
Digital video recorders (DVRs) are being used by many users. A service is provided where users can automatically record videos, such as TV shows, movies, or any other media, using their DVR. The DVRs provide enhancements for shifting the viewing time to a time that is preferred by viewers. For example, viewers may fast forward the media to a point that is desired. However, the process for shifting the viewing time is tedious and time-consuming. For example, while a user is watching different television shows, the user may have to fast forward the media multiple times. The user may have to manually start the fast forwarding and then manually stop the fast forwarding at the right time to continue watching the show.

DESCRIPTION OF EXAMPLE EMBODIMENTS
Overview
In one embodiment, a method for performing actions with media information using a digital video recorder is provided. In one embodiment, a user may mark a media segment in media using a digital video recorder. For example, a user may mark the beginning and end of a section in a video, such as an advertisement. Characteristics for the media segment are then determined. A second media segment in second media may then be determined. For example, the second media segment may have similar characteristics to the first media segment. In one example, an advertisement that is similar to the advertisement marked as the first media segment may be determined. An action may then be performed with the second media segment. For example, the second media segment may be removed from the second media. In one example, advertisements that have been marked in the first media may automatically be removed from the second media. Thus, the user does not have to continually fast forward over advertisements that have been deemed undesirable. Other actions may also be performed, which will be described in more detail below.
Example Embodiments
FIG. 1 depicts an example of a system for processing media. As shown, a primary DVR 102-1 may be operated by a user using input device 104. DVR 102-1 may receive media from media sources 110. For example, the media may include video, audio, data, Internet website material, video-on-demand, streaming video, webcasts, etc. Also, the media sources 110 may include a cable operator, satellite provider, Internet website, or any other service provider. Further, media sources 110 may be tangible media, such as digital video disks (DVDs), compact disks (CDs), etc.
DVR 102 may be any device capable of recording media. For example, DVR 102 may include digital video recorders, video recording servers, personal computers with video recording capability, media personal computers (PCs), or other recording devices. DVR 102 records media that may be received from media sources. The media may be recorded as specified by the user. For example, the user may specify which media should be recorded. In one example, different TV shows, movies, etc., may be recorded.
Media may be any information that is received by DVR 102 from media sources. DVR 102 may record the media and store it in storage, which may be local to DVR 102 or distributed among other storage devices. Also, DVR 102 may facilitate displaying the media on a display device 106, which may be a television, monitor, portable video player, or any other display device.
Input device 104 may be a remote control, keyboard, or any other input device. Input device 104 may be used to control DVR 102. For example, input device 104 may be used to time shift media. That is, a user may fast forward, rewind, or perform other time shifting operations with media. In yet another example embodiment the input may be a voice activated device which utilizes adaptive speech recognition or a natural language recognition.
Portions of the media can be marked by a user. For example, a segment of media may be marked using input device 104. Various input methods may be used, such as a user may select a start button at the beginning of a media segment and an end button at the end of the media segment to identify the media segment. Particular embodiments can then determine other media segments that may be related to this media segment. For example, characteristics of the marked media segment may be determined. The characteristics may be used to identify other media segments that include similar characteristics. For example, when an advertisement is marked, the characteristics of the advertisement are used to find other instances of the advertisement, such as instances found later in the media or in other media. DVR 102 may then perform an action with the identified media segments. For example, the identified media segments may be removed. Thus, if a user marks an ad, other instances of the ad may be removed. Although removal is contemplated, other actions, such as fast forwarding, may also be appreciated.
A community of users or a social network may also be formed. For example, users of DVRs 102-2, 102-3, 102-4, and 102-5 may be connected to a user of DVR 102-1 in the social network. Connected users may then share information. The term “user” and “DVR” may refer to the connection between the users and their equipment. For example, a user may have his/her own DVR in his/her home or may be assigned a DVR by a service provider.
When a user of DVR 102-1 marks a media segment for removal, information for the media segment may be communicated to DVRs 102-2-102-5 over a network 112. Network 112 may be an Internet Protocol (IP) network, local area network (LAN), wide area network (WAN), etc. DVRs 102-2-102-5 may then determine an action to perform. For example, the same media segments in media stored at DVRs 102-2-102-5 may also be removed. The removal may be based on different rules that may be configured, which will be discussed in further detail below.
DVR 102-1 may communicate with DVRs 102-2-102-5 through different methods. For example, an intermediate device, such as a server 108, may be used to communicate with DVRs 102-3 and 102-4. Also, peer-to-peer communication may be provided where DVR 102-1 communicates with DVR 102-2 and 102-5 over network 112. If server 108 is used, a central database may be provided where information on media segments marked by DVR 102-1 may be stored at server 108. DVRs 102-2, 102-3 and 102-4 may then access the database and determine any actions to perform based on the stored information.
FIG. 2 depicts a more detailed example of DVR 102. As shown, DVR 102 includes a media marker 202, a media analyzer 204, a media segment searcher 206, storage 208, an action performer 210, and a community communicator 212.
Media marker 202 receives information for marking media. For example, input device 104 may be used to mark a segment of the media. Also, any media editor may be used, such as an application on a personal computer, etc. Media marker 202 may store information that identifies the media segment. For example, a start time and an end time in the media may be stored. The marked media segment may be repeated in numerous recordings, such as a television advertisement. In one example embodiment, extensible markup language (XML) tags can be used to mark specific media segments.
Media analyzer 204 may determine characteristics of the marked media segment. In one example, the characteristics for the marked media segment may be determined in real time when the media segment is marked. The characteristics may be voice and/or video signatures. In one example, a frequency spectrum of the video signature is based on a two-dimensional Fourier transform. Other methods for determining characteristics of media, such as pattern recognition, may be employed.
Media segment searcher 206 is configured to determine other media segments of media stored on storage 208 using the characteristics for the marked media segment. For example, media segments in storage 208 that include similar characteristics to the characteristics of the marked media segment may be determined. These may be considered potential related media segments. For example, the potential related media segments may be similar advertisements to the one marked.
To determine potential related media segments, characteristics of media in storage 208 may have been analyzed previously. This may make the searching process faster. For example, voice and video signatures may be determined from all media stored in storage 208. In one example embodiment the system attaches a media tag that indicates the source of the recording and the time it has been recorded. For example, the tag may indicate that a specific media clip was recorded from channel 5 at 11:35 PM. Using DVR 102, users may select different media to be recorded at different times. After recording, media analyzer 208 may determine characteristics of the media. The characteristics of the marked media segment and the actual media may be stored in storage 208. For example, various television shows, movies, etc. may have been recorded and stored in storage 208, such as a hard drive of DVR 102. Characteristics of the media may be associated with the media. For example, the characteristics may be stored with the media, indexed to the media, etc.
Action performer 210 then determines an action to perform with the potential related media segments. For example, the potential related media segments may be manipulated in media in storage 208. In one embodiment, action performer 210 displays potential related media segments to the user and asks for authorization for performing an action. For example, action performer 210 may prompt the user to okay skipping of the potential related media segments. The skipping may be removal of the segment from the media, logic that automatically skips the segment when it is encountered during playback, etc. Action performer 210 may remove the potential related media segments from the media. For example, a first TV show may include an advertisement for a beer. A second television show may also include a second advertisement for the beer that may be the same advertisement, a similar advertisement by the same brand, a similar advertisement in the same genre, etc. The second advertisement may also be an unrelated advertisement but a rule may be used to determine the second advertisement based on the characteristics of the marked media segment. For example, marking of a beer ad may cause removal of ads for soft drinks (possibly because they are both drink related).
In one embodiment, action performer 210 may remove the potential related media segments from the second TV show. Although the media segments may be removed, other actions may be taken. For example, in another embodiment, action performer 210 may mark the beginning and end of a potential related media segment in the media. When DVR 102 then encounters the potential related media segment during playback, skipping of the potential related media segment may be provided. For example, the user may decide to skip the segment using a “fast forward”, “skip” or “next segment” command on input device 104. In yet another embodiment, action performer 210 may insert logic that automatically skips the potential related media segment when it is encountered during playback. For example, DVR 102 may automatically start fast forwarding the media during the related media segment.
Potential related media segments may be determined at any time. For example, once a user marks a segment as being undesirable, DVR 102 may determine other potential related media segments and perform the appropriate actions, such as removing the advertisements from other media. In another embodiment, DVR 102 may analyze the characteristics in real time as media is playing and/or being recorded and then takes the appropriate actions, such as removing the potential related media segments.
FIG. 3 shows an example of a media that include similar media segments. As shown, first media 302 has a marked media segment 304. Second media 306 and third media 308 are also provided. Second media 306 may include a media segment 310 and third media 308 may include a media segment 312. Media segments 310 and 312 may be found at different points in second media 306 and third media 308. Media segment searcher 206 is configured to search characteristics of second media 306 and third media 308 to determine segments that have similar characteristics to marked media segment 304. Thus, media segments in different media may be determined based on marked media segment 304. For example, first media 302 is a first television show in a series, second media 306 may be a second television show in the series, and third media 308 is the third show in the series.
As discussed above, a social network may be provided. FIG. 4 depicts an example of a method for communicating between users in the social network. DVR 102-1 includes a rules determiner 402-1 and a community communicator 212. In one embodiment, a trust may be established amongst similar-minded people that form the social network. This trust may be translated into a willingness to share information amongst the social network. For example, information may be shared about the marking of media segments, such as the characteristics of marked media segments.
Rules determiner 402-1 determines users in which information should be shared. For example, all users that may be connected to the user of DVR 102-1 may be selected to receive information. Also, in another example embodiment only users that are in a friends list, first degree friends, second degree friends, etc. may be selected.
Community communicator 212 enforces and facilitates communication amongst users of a specific social network. For example, the information may be communicated to a DVR 102-2. A community communication receiver 404 receives the information, such as the characteristics for a marked media segment.
A rules determiner 402-2 determines rules to apply to the received information. Rules that may be applied include determining if an action should be taken. Even though the characteristics have been received because the user of DVR 102-1 sent them to DVR 102-2, a second user of DVR 102-2 may or may not want to have an action taken based on the characteristics. For example, depending on the second user's trust of the first user, an action may or may not be taken. In one example, a second user may trust the first user's decisions in marking media and thus may automatically determine that similar media should be removed. However, the first user may not have built up enough trust with the second user and thus the media segments may not be automatically removed but may be marked and shown to the second user for their approval for deletion. Also, a number of users may need to mark a media segment for removal before any action is taken. In one example, if only one user decided to remove the media segment, there might not be enough trust to have the segment automatically removed. However, if the media segment has been removed by multiple users, such as ten users, then the rules may specify that the media segment should be automatically removed.
In one embodiment, rules may also apply to the social network as a whole. For example, the rules may determine which users can alter the viewing policy of the social network and which users can subscribe to the network and thus leverage the social network's viewing policies. In one example, some users may be able to mark media segments for removal in media for all members of the social network. Also, users may mark how important a media segment is, such as a segment may be high priority or low priority. A high priority segment may be a segment that a user is recommending to another user. A recommendation is then sent to other members of the social network.
Also, some members may be designated as non-marking members that can only use the viewing policies. Other rules may also be applied.
An action performer 210 then performs the action. For example, the media segments may be removed as described above in FIG. 2, marked for skipping, etc.
The sharing may be done peer-to-peer. However, another embodiment may use a central database 406, which may be included in server 108. Although a single database 406 is described, it will be understood that the database may be distributed, such as the database may be distributed in multiple storage devices attached to the network. Also, the storage may be distributed in multiple DVRs 102.
In one embodiment, community communicator 212 may communicate the characteristics for media segments that have been marked to database 406. Other DVRs 102 may also access database 406 for updates.
One example for using particular embodiments will now be described. A first user may identify an advertisement and mark it accordingly. The information for the advertisement is then made available to all the users in the first user's social network. In a small group with high trust, a marking by one person may cause advertisements similar to the one identified not to be played by DVRs for users in the social network. For larger social networks, other actions may be needed to cause skipping of an advertisement. For example, if fewer than 100 users approve the skipping of an advertisement, the advertisement will still be played but users may have the option of accepting this skipping by marking the advertisement as undesirable or rejecting the skipping. Once a threshold of users have been reached that have marked the advertisement for skipping, then the advertisement may be automatically skipped during playing of media for users in the social network. In another embodiment, if the system detects that there are conflicts when one user marks a media segment for removal but others desire to keep it in, then the system may suggest that the social network be split into separate groups who seem to have different tastes.
FIG. 5 depicts a simplified flow chart of a method for performing actions with media. Step 502 receives a marking of a media segment in media. For example, an advertisement may be marked at specific times in media.
Step 504 determines characteristics for the media segment. For example, a voice or video signature of the media segment may be determined.
Step 506 identifies other media segments based on the characteristics of the marked media segment. For example, other media segments with characteristics similar to the characteristics of the marked media segment may be determined. In one embodiment, these may be the same ads that may appear frequently in different media.
Step 508 then performs an action with the identified media segments. For example, they may be marked for removal or skipping.
FIG. 6 depicts an example of a method for determining what actions to perform based on segments marked by other users. Step 602 receives information for media segments that were marked by other users. For example, the characteristics for a marked media segment may be received.
Step 604 determines rules for an action to perform. For example, the rules may determine how trusted the other users are. It may then be determined whether or not an action should be performed with similar media segments.
Step 606 identifies media segments using the information received for the marked media segment. For example, media segments that include similar characteristics to the marked media segment may be determined.
Step 608 then performs an action with the determined media segments based on the rules. For example, these media segments may be marked for removal or skipping during playback.
Particular embodiments provide many advantages. For example, an automated method for marking undesirable media segments for removal is provided. This reduces time a user needs to spend to fast forward past undesirable media segments that may be repeated across multiple media. Further, a social network is provided where information may be shared to allow actions to be performed based on marked media segments. For example, other users may have the media segments removed based on actions of other users. The information may be shared based on recommendations and trust of other users. Accordingly, the social network provides an efficient method to remove undesirable media segments. Also, the social network may be used to determine which media segments may be undesirable. For example, if advertisements are consistently skipped, then information may be sent to the advertiser indicating the advertisement's undesirableness. However, other advertisements may not be skipped and it may be determined that this advertisement is desirable. Advertisers may then decide to show the more desirable advertisement instead of the undesirable advertisement.
Although the description has been described with respect to particular embodiments thereof, these particular embodiments are merely illustrative, and not restrictive. Although advertisements are described, it will be understood that any media may be used. Further, any actions may be taken based on the characteristics of a marked media segment.

21. Logic encoded in non-transitory media that includes code for execution and when executed by a processor is operable to perform operations comprising:
identifying a marking of a first portion of first media by a user, wherein the marking of the first portion of the first media indicates that the first portion of the first media should be omitted in subsequent playbacks of stored media;
determining, using at least one processor device, that the marking is a trusted marking to be applied to media stored on both a corresponding digital video recorder of the user and digital video recorders of other users;
determining, using at least one processor device, characteristics of the first portion of the first media based, at least in part, on the marking of the first portion of the first media by the user;
identifying a commonality between the first portion of the first media and a particular portion of second media stored on a particular one of the digital video recorders of the other users based, at least in part, on the determined characteristics of the first portion of the first media, wherein the second media is different from the first media and the particular portion of the second media is less than all of second media; and
causing the particular portion of the second media to be omitted from playback of the second media from the particular digital video recorder based on the marking.
