Method of regulation of the flow rate of assistance data for the reconstruction of images producing series collectors under - sampled

摘要

The field of the invention is that of the coding of assistance data for the reconstruction of images electronic driven under - sampled, particularly for the transmission channel hdtv on mac. / p & & p & the objective is to provide a method for regulating the flow rate which pass through a channel with a fixed flow rate of assistance data encoded with a variable flow rate of the type using a compression process comprising a step of selection, for each elementary block of image of optimum treatment of several compression processes are competitors carried out in parallel, in particular comprising at least one treatment with low consumption of the flow rate, at least one treatment with high consumption of the flow rate. / p & & p & according to the invention, the process is characterized in that it forces the choice of treatment required from one of the treatments 11 at a low consumption, during the step of selecting the optimal treatment, when the flow 13 of the assistance data approach or exceeds the flow rate permitted by the transmission unit 10.
