METHOD OF TRANSCODING VIDEO DATA WITH FUSION OF CODING UNITS, COMPUTER PROGRAM, TRANSCODING MODULE AND TELECOMMUNICATIONS EQUIPMENT ASSOCIATED THEREWITH

Method of transcoding video data with fusion of coding units, computer program, transcoding module and telecommunications equipment associated therewith. Method of transcoding video data between a first and a second format (F1, F2), the method comprising a step of decoding the binary stream (FB1) providing decoded video data, data representative of the coding structure of the frames in the first format (F1) and, for all or some of the first coding units, prediction data, and a step of re-encoding in the course of which the decoded video data are encoded in the second format (F2). During the re-encoding step, an intermediate coding structure is constructed, comprising intermediate coding units constructed so as to correspond to the fusion of one or more first coding units, prediction data are allocated to each of the intermediate coding units, and the decoded video data are re-encoded in the second format (F2) as a function of the intermediate coding structure.
