ABSTRACT:
A method for detecting errors in an image signal. The image signal is produced by dividing an image into image blocks, and coding is performed in which at least predictive coding is performed on an image block to produce inter-coded image information for the image block. The inter-coded image information comprises at least one prediction error block containing prediction error information. A decoding is performed to recover prediction error information contained in the at least one prediction error information contained in the at least one prediction error block. A prediction error block check is performed in which prediction error information contained in the at least one prediction error block is examined to detect errors in the inter-coded image information for the image block.
