PROBLEM TO BE SOLVED: To provide a solution for human influence on blocking caused by block coding or problem of blocking effect. SOLUTION: A form of video source coding is proposed that is particularly suitable for transmission over a channel at a low bit rate and with a high error rate, such as a wireless transmission channel. It proposes to use block coding with motion prediction and employing a plurality of reference pictures. The reference pictures are subject to block effect filtering. A reference picture is selected when coding a picture. By using a plurality of reference pictures, transmission channel time propagation errors are limited. Since the reference pictures are subject to block effect filtering, transmission timing errors are corrected independently of intrinsic error caused by block coding. |
