摘要:
A method and apparatus for distributing live video to multiple client devices is provided herein. In particular, a router is provided that acts on behalf of all client devices in its network. The router serves multiple groups of client devices with each group being formed by client devices having similar bandwidth requirements. The router then requests and receives video chunks from a network. The router then redistributes the video chunks to the multiple client devices using a multicast transmission. In particular, to minimize the demands on the core network, the router sets up a separate multicast to each group. Live video, of the appropriate quality is then multicast to each group.
