Abstract
The invention relates to a method of analyzing at least one video sequence present on at least one sending apparatus, in a communication network also comprising at least one receiving apparatus, wherein, the video sequence being compressed with an encoding method which generates a bitstream comprising information representing the temporal activity of the images of the video sequence and information representing the spatial activity of the images of that video sequence, and the temporal and spatial information being distributed between one or more spatio-temporal hierarchical levels, the method comprises the following steps performed at the receiving apparatus: obtaining information representing the temporal activity of the video sequence present on the sending apparatus, analyzing the temporal information obtained, as a function of the result of the analysis, deciding whether the generation of a request destined for the sending apparatus for the obtainment of information representing the spatial activity of the video sequence is necessary.
