Video encoding method, video decoding method, video encoding apparatus, video decoding apparatus, video encoding program, and video decoding program

摘要

A video processing system is provided with video encoding apparatus 1 and video decoding apparatus 2. The encoding apparatus 1 outputs a maximum delay time that is incurred by backward prediction, in addition to encoded data D1 resulting from encoding of video data D0. The decoding apparatus 2 effects input of the maximum delay time that is incurred by backward prediction, in addition to encoded data D1 from the encoding apparatus 1. Then the decoding apparatus 2 decodes the encoded data D1 with reference to the input maximum delay time to generate motion video data D2.

1. A method of decoding encoded pictures, the method
comprising: receiving an encoded picture (n) and a delay time syntax [dpb_output_delay(n)], wherein n is integers, and the dpb_output_delay (n) represents a time period defined uniquely for the encoded picture (n); decoding the encoded picture (n) at a decoding timing tr(n) into a decoded picture (n); defining an output timing to(n) as to(n)=tr(n)+dpb_output_delay(n); and if to(n)>tr(n), holding the decoded picture (n) in a decoded picture buffer for a time period represented by the dpb_output_delay(n) before outputting the decoded picture (n) from the decoded picture buffer for display, wherein the decoded picture buffer holds at least one decoded picture used for reference to decode at least one of the encoded pictures.
