Abstract:
Various systems, methods and devices adaptively manage the multicast delivery of multiple media programs. Each of the media programs is encoded into multiple media streams, each stream having a different bitrate, frame rate, resolution or other encoding parameter. A computer receives feedback about the delivery of the multiple streams and automatically adapts the number of streams available for at least one of the multiple media programs in response to the received feedback. This allows resources to be applied to those multicast streams having the greatest user demand.
