Method and apparatus for video signal processing |
摘要 |
A first video signal processor (103) receives a first encoded video signal from which a video unit (201) generates a second encoded video signal, where the second encoded video signal is a reduced data rate version of the first encoded video signal. An error encoder (203) generates error redundancy data for the second encoded video signal and a multiplexer (207) generates output video data comprising the first encoded video signal and the error correcting data but not comprising the second encoded video signal. A second video processor (105) receives the output video data and a video unit (303) regenerates the second video signal from the first video signal. An error unit (305) detects errors for at least a first segment of the second video signal in response to the error redundancy data. A combiner (307) then generates combined video data by combining corresponding segments of the first encoded video signal and the second encoded video signal.
