摘要
An object with embodiments of the present invention is to achieve a solution for fast channel change that improves bandwidth utilization, wherein the fast channel change is accomplished by initiating a unicast stream until a multicast stream can provide the desired media. The bandwidth utilization is achieved by delaying the multicast session and by terminating the unicast session at the latest when the multicast session starts. The delay of the multicast session is dependent on the network latency. Latency in this context refers to the time passed from when the client sends an IGMP JOIN message until it receives the first packet of the multicast stream.
