<p>The invention relates to a video coding method applied to an input signal IS consisting of a sequence of frames represented by one luminance matrix and two chrominance matrices. This method generates a coded bitstream CB 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 level description the presence, or not, of chrominance components in said coded bitstream, and therefore allowing to deliver, at the decoding side, the information according to which chrominance descriptive elements have to be decoded, or not.</p> |
