MULTIMEDIA INFORMATION COMMUNICATION DEVICE AND ITS METHOD

摘要

In a media separating unit, a data separating section separates a video packet and an audio packet, a CRC computing section carries out again the same computation carried out by the encoding side through a CRC code separating section and outputs the result of the computation to an error information adding section. The error information adding section compares the result of the computation with a CRC code added to the video packet to check whether they agree with each other. After the check, the error information adding section adds the result of the check as error information to the video packet and outputs the video packet as a new video packet to a video decoder through a buffer.
