Abstract

A method of decoding coded image data, preferably coded according to CCITT Recommendsation H. 261, wherein the data stream is continuously monitored for transmission errors by utilizing the residual redundancy of the data stream, and pixel values reconstructed after the detection of a transmission error are not entered into the predicted-image memory until a subsequent starting code word for a frame or field has appeared.
