Perfect stream in relation to FCC/RET

Perfect stream can enhance the end user experience by removing network induced faults to the multicast stream. The egress of the perfect stream can be fed back into a separate ISA for the FCC/RET application. This ensures that the end user gets the best IPTV viewing experience from the start of a channel change. The perfect stream can be sent to the FCC/RET ISA by using extranet where FCC/RET resides on a separate VPRN instance.
