Abstract
An implementation is described herein, which facilitates a fast channel change by receiving and decoding a unicast acquisition media stream that corresponds to a soon-to-be-requested target multicast media stream. It does this before requesting the target multicast media stream of the new channel. Once the transmission of the unicast stream is caught up with the multicast stream, this implementation splices from the unicast acquisition stream to the target multicast media stream.
