ABSTRACT:
A method for processing error codes in compressed encoded images transmission is disclosed. In this method, when error codes have been detected at the receiving end, the image code stream data with error codes is discarded before decoding the image code stream data, and the discarded image code stream data is replaced with the image code stream data located at the corresponding location of the previous frame, and image code stream data is decoded continually. More preferably, the method further comprises: setting a mark array for the image code stream data before decoding at the receiving end to record the locations where error codes have been detected. With this method, sending intra-frame images at transmitting end and freezing images at receiving end are avoided or their occurrence times is reduced, so image quality is thus improved.
