  • Method and apparatus to facilitate the efficient implementation of trick modes in a personal video recording system
    Patent number: 8879896
    Abstract: A method and apparatus are disclosed for facilitating efficient operation of trick modes in a personal video recording (PVR) system. Stream-navigation data from a data stream is captured and pre-processed to generate a frame-correlated NAV table comprising one entry for each frame within the data stream, during recording of the data stream. The stream-navigation data comprises start code data, content rating data, and conditional access data that is embedded in the data stream. During playback of the data stream in a user-selected trick mode, the frame-correlated NAV table is used to generate command packets that are sent to a data decoder along with selected frames of the data stream. The selected frames are decoded based on information in the command packets and certain selected frames may be displayed as part of the trick mode.
