  • Publication number: 20110075994
    Abstract: A method and system for providing functionality similar to that found in a DVR but mostly or completely contained within a television set is disclosed. A memory stores packets representing a portion of one or more programs in the broadcast stream and allows a viewer to replay that portion of the program using some of the functions available on a DVR, such as pause, rewind, and fast forward. The packet stream is divided into groups of equal length and fixed time duration, for example one second, and stored in sequential order in the memory. This allows for the storage and retrieval of content without the need for an index file, without adding a timestamp to the program data packets, and without separating the audio portion from the video portion of the program and then having to synchronize and recombine them.
