- the "skip commercial" button is provided on a remote control.
- a first voice print profile is selected from the collection of stored voice print profiles.
- a search is performed to look for similar profiles in the collection.
- a similar profile indicates a high probability that an actor's identity is the same in both instances. Further, the time stamps of the search results are examined to determine if the profile is likely to be part of the main program.
- the current profile is marked as "Part of the Main Program" at step 708. Otherwise, a search is performed, to look for matching profiles in isolated time blocks of approximately 30 seconds at step 710. The profiles are considered isolated if they occur at intervals. If the profiles match then they are marked as "Part of a Commercial" at step 712. In an embodiment of the present invention, if the profiles fail to get categorized as part of the program or as a commercial then the profile will be marked as "Unsure" at step 714.
- the system controller gets the next voice print profile to be characterized. If this was the last profile in the collection then it goes back to the first profile in the list and starts the analysis anew at step 704. This is a continuous process thai impro ves its accuracy as more data becomes available. Accordingly, it runs in the background contemporaneously.
- flow diagram 800 depicts a method of further processing and identifying commercials based on the audio characterization, in accordance with an embodiment of the present invention.
- a sequential group of voice print profiles are examined by the software.

- the request may include channel identification information, show identification information and/or geographic informa tion of where the user is loca ted.
- the central service searches for corresponding content for the identified channel/content for the particular geographic location. This assists to readily identify the desired content. Accordingly, for content that is broadcast multiple times the server may be able to provide useful commercial identification data for the current broadcast based upon historical broadcasts. The system controller uses this information to identify commercials automatically or otherwise to assist in the identification of commercials to increase the degree of certainty that particular content is a commercial.
- the central service may not have commercial identification information for a particular channel for a particular geographic location.
- the central service may search an electronic program guide or other database that includes information related to what particular show is being shown on the requested particular channel for the relevant geographic location.
- the data provided to the central service may likewise include program identification information or is otherwise associated by the central service with program identification information, such as program name and description.
- the central service may include program identification associated with the identification of commercials therein (or otherwise the pattern of commercials) for that particular content,
- the central service may likewise update its data for a particular show and/or content based on data retrieved from additional sources.
- the central service may simply remove the commercial location information in order to reduce the likelihood of providing false data.
- the actor and/or characteristic data may still be useful.
- the central service may likewise download data to the audio video systems on a periodic basis so that the audio video systems have commercial identification data for much of the content that the user may desire to view in the near future. This downloading of data may likewise be based upon the user's viewing history.
- the systems may be interconnected in a peer-to-peer fashion, a client-server fashion, or a hybrid of the two.
- the viewer while the commercial is being slapped in real time, the viewer will have 30 seconds, 60 seconds, or more, to wait until the desired content is continued. During this time a "save and return" button on the remote control may be pressed which switches to another channel temporarily, and returns to the previous channel when the desired content resumes. In this maimer, the viewer will not be presented as many commercials.
- news from the Internet or other content from the Internet may be provided to the viewer. This content from the Internet may be pre-selected, such as a customized web page, of stock prices, local news, national news, sports scores, present text messages that have been received, provide e-mails.
- a user may be watching different programs at the same time, such as a first football game and a second football game at the same time.
- a commercial occurs the system may automatically switch to the other football game. Further the system may switch back to the first football game when commercials end. This process may be repeated until the content for both football games has been presented. In this manner, the viewer may watch both football games without watching the corresponding commercials.
- the portions of the football games not currently being presented to the viewer in realtime may be stored on a storage device and presented to the viewer from the storage device when the switching occurs.
- the commercial identification and skipping system may likewise be applied to multiple radio channels, such as a pair of talk radio shows.
- the system controller may be implemented as a stand-alone commercial editing system provided in-line with the audiovisual content being provided to the television.
- the system may be embedded in a television. In this case, some of the processing pipeline of the television may be used.
- a digital video recorder similar in nature to a Tivo TM , may be used to record and process content.
- a general purpose computer may be used. In many cases, it may be desirable to use the network connectivity of a cellular phone to download data to the system and provide uploads of data to the server (or other device).
- the network connectivity of the television or internal network connectivity may be desirable to use the network connectivity of the television or internal network connectivity to download data to the system and provide uploads of data to the server (or other device).
- system controller/ central service may likewise develop a set of characteristics of particular actors. When these actors are anticipated, to be present in a particular show (such as information available from an electronic programming guide) then one or more actor characteristics will already be available. This is also suitable for audio characteristics. This library of audio characteristic content reduces the computational demands on the system and server.
- system controller/central service may likewise develop a set of anticipated commercial patterns for one or more different types of content. The type or content may be available in a database or electronic program guide, on the system, server or otherwise, and therefore provide information to assist in the identification of the commercials.
