摘要：
The present invention provides a method of multicasting video streams. The method includes accessing, at a base station, a first packet from a video stream that includes a plurality of packets. Each packet in the video stream is assigned to either a base layer or at least one enhancement layer. The method also includes encoding the first packet using a coding scheme selected based on whether the first packet is assigned to the base layer or an enhancement layer.
