ABSTRACT:
The Real-time Transport Protocol (RTP) and its related standards define a retransmission packet format and a way to give feedback via Negative ACKnowledge (NACK) packets for data that has been lost. In one embodiment, a unicast RTP repair session is associated with a main Source Specific Multicast (SSM) multicast session. Real-time Transport Control Protocol (RTCP) NACK packets are then used for feedback to a SSM feedback target address. This dynamically instantiates unicast RTP repair for multicast sessions. The repair scheme can be used for repairing multicast channels or joining new multicast channels. In another embodiment, a media transmission device shares an IP address with one or more other media transmission devices. The shared IP address can also be used to route multiple identical multicast media streams to different media stream receivers.
