Abstract
A video sequence is encoded by encoding key frames to obtain coded data and non-key frames to obtain error-correcting information. In the encoding process, key frame data are stored in a buffer, first motion information pertaining to the key frames is obtained, and the first motion information is applied to the stored key frame data to generate predicted key frame data. Second motion information pertaining to the non-key frames is also obtained and used to generate predicted non-key frame data. Either the first motion information is obtained from the second motion information, or the second motion information is obtained from the first motion information. The encoder accordingly does not have to obtain motion information from the decoder, and can estimate the amount of error-correcting information to send to the decoder.
