A METHOD AND DEVICE FOR ADAPTING A TEMPORAL FREQUENCY OF A SEQUENCE OF VIDEO IMAGES

摘要

The invention concerns a method of adapting a temporal frequency of a sequence of video images for the purpose of its transmission over a communication network, characterized in that images of the sequence having been sampled at a temporal frequency f₁. The method and device for adapting a temporal frequency of a sequence of video images, the method comprises a step of deciding as to the carrying out of a step of simulating a coding of images of the video sequence sampled at a temporal frequency f₂ > f₁, for the purpose of determining whether the sampling temporal frequency fa method and device for adapting a temporal frequency f₁of the sequence can be increased, the decision being taken on the basis of at least one criterion (409; 513) relative to the resources of a communication apparatus able to perform the simulation step (412; 516) and/or on the basis of the evolution over time of the characteristics of the video sequence and/or of the network (512, 515).
