Video analyzer and video error detector

摘要

Since a delaying part ( 14 ) delays transmission of a video signal, the timing at which a decoded video signal is input into a multiplex processing part ( 16 ) matches the timing at which an analysis result from an encoded information analyzing part 13 is received by the multiplex processing part ( 16 ). It is, therefore, possible to perform processing for showing the quality level of a video on the same screen, and thus a large capacity memory is unnecessary.
