  • Apparatus and methods of multiplexing data to a communication channel
    Patent number: 6490298
    Abstract: Apparatus and methods for multiplexing data received from a plurality of sources to a communication channel. Each of the sources is assigned to one of at least two scheduling layers based in part upon one or more bit rate characteristics of the sources.
    Type: Grant

  • Analyzer and methods for detecting and processing video data types in a video data stream
    Patent number: 6041142
    Abstract: A video data stream analyzer modifies an input digital video signal so that the resulting output digital signal can be optimally compressed by a digital video encoder. The video data stream analyzer eliminates redundancy in the input video signal, and reorganizes the input video signal so that the spatial and temporal redundancy is increased. In addition, the video data stream analyzer generates side channel information that is supplied to the video encoder. The side channel information tells the video encoder whether vertical frame-based filtering or vertical field-based filtering is preferable. Additional side channel information specifies the order and duration of the display of the fields after decoding and this information preferably is encoded with the video signal.
