Abstract
A method and apparatus are provided for transmitting, over a wireless link, video that is coded in multiple layers such that higher priority for the use of the transmission resources may be given to the lower layers of the layered video stream. The level of priority is signified by the session identification parameters, i.e., by the source and destination ip addresses and port numbers. These parameters are assigned to the base layer and to the one or more additional layers, respectively, such that at least two of said layers are assigned different parameter sets. At least the base layer is then transmitted on the wireless link.
