Patent ID: 8599919

Claim:
A moving image decoding apparatus, comprising: an information reading means for reading information added to coded data; a decoding buffer for storing target amount coded data in which a moving image is coded within a target code amount set in advance, excess coded data in which a part exceeding the target code amount is coded, and the added information to be read; a target amount decoding portion for decoding the target amount coded data; at least one excess decoding portion for decoding the excess coded data; and a synthesizing portion for synthesizing decoded images decoded by the target amount decoding portion and the excess decoding portion and outputting the synthesized image, and wherein, as a discarding determination criteria of the excess coded data, the added information includes at least any of: a delay estimation value that indicates a delay of the excess coded data with respect to the target amount coded data; a buffer size of the decoding buffer; load of the moving image decoding apparatus; and resolution of a display screen of a receiving terminal, and wherein the excess coded data is discarded from the decoding buffer, based on a situation of the receiving terminal and the discarding determination criteria.
