MULTI-MEDIA INFORMATION COMMUNICATION EQUIPMENT AND METHOD THEREFOR

摘要

PROBLEM TO BE SOLVED: To prevent a decoding processing from becoming a waste in the case that an error is present and to quickly perform an error propagation evading processing thereafter. SOLUTION: In a medium separation part 4, a data separation part 41 separates a video packet 100 and an audio packet 200 and a CRC arithmetic operation part 43 performs the same arithmetic operation as the arithmetic operation performed on an encoding part again through a CRC code separation part 42 and outputs the arithmetic result to an error information addition part 44. In the error information addition part 44, the arithmetic result and a CRC code added to the video packet are compared and whether or not they match is judged. Then, when a judged result is generated, the error information addition part 44 adds the judged result to the video packet 100 as error information and outputs it through a buffer 7c to a video decoder 5 as a new video packet 110.
