Video process where part of compressed version of video signal accompanies video signal itself |
摘要 |
After decoding of an MPEG bitstream to the form of a video signal, an information stream signal in the form of all or part of the MPEG bitstream, is transmitted alongside the video signal, embedded in the least significant bit. Recording may simply involve extraction of the embedded MPEG bitstream or, if only part of the bitstream has been embedded, an essentially "dumb" coding operation guided by the information stream signal.
