| 摘要 |
The invention relates to a video coding method applied to a sequence of frames and generating a coded bitstream in which each data item is described by means of a bitstream syntax allowing any decoder to recognize and decode all the segments of the content of said bitstream. According to the invention, which finds an application for instance within the video compression standards of the MPEG and ITU-H.26X families, the syntax comprises a flag provided for indicating at a high description level, for each channel described in the coded bitstream, the presence, or not, of an encoded residual signal, said residual being defined by means of a prediction technique, applied to previously decoded frames and followed by the construction of said residual signal. |
