摘要： This method of transmitting coded data, representing a digital video, from a server to a plurality of clients, at least one subset of the clients using congestion control algorithms, uses a plurality of signals for passing from a coded representation of the video at a given quality level to a coded representation at least one quality level different from the given level. The sending (E618) of at least one of the passage signals at least to the subset of clients depends on information representing the behavior of the congestion control algorithms used by the subset of clients.

摘要： A method of temporal prediction using motion estimation is implemented in a sequence of digital images, in the context of coding in a bitstream comprising at least first and second layers linked to each other in a chosen hierarchical relationship of scalability. Provision is made for constructing at least one set of reference pixels for the temporal prediction on the basis of information from a prediction image of the second layer and complementary information from an image of the first layer corresponding temporally to the prediction image. For each block of the current group of the image of the current second layer, a search is made for at least one block of the reference set of pixels so constructed that is suitable for the temporal prediction; and at least one corresponding motion vector is determined.
