  • Patent number: 6567127
    Abstract: A method and apparatus for video compression that provides support for the inclusion of VBI data and copy protection data in an enhanced encoded video data stream is presented. A received video signal is separated such that a video data stream and a VBI data stream are produced. The video data stream is encoded to produce a compressed video data stream. The various types of VBI data that may be included in the VBI data stream are isolated, and one or more are selected for inclusion in the enhanced video data stream. The compressed video data stream is then combined with the one or more VBI data type streams to produce the enhanced video data stream. In other embodiments, copy protection information in the video signal is also detected and encoded such that it also can be included in the enhanced video data stream. The enhanced video data stream can be stored in memory or some other type of storage media for retrieval at a later time.
