Claim:
1. An encoding apparatus for encoding, by distributed video coding, a sequence of moving-picture frames that has been divided into a sequence of key frames and a sequence of non-key frames, the encoding apparatus comprising: a key frame encoder for encoding the key frames to generate coded data; and a non-key frame encoder for encoding the non-key frames to generate error-correcting information, wherein the key frame encoder comprises wherein the non-key frame encoder comprises wherein information representing the first motion is generated in the key frame encoder and supplied to the second motion information generator, wherein the second motion information is generated in the non-key frame encoder and supplied to the first motion information generator, wherein the first motion information generator generates the first motion information by extrapolation from the second motion information supplied from the non-key frame encoder, wherein the second motion information generator receives, as the information representing the first motion, the key frame data from the first key frame buffer, and generates the second motion information based on the received key frame data, wherein the key frame encoder performs intraframe and interframe encoding of the key frames, and further comprises: wherein the first key frame buffer stores the output of the adder as the key frame data.
