Abstract: A broadcast multimedia data stream is partitioned into two or more parts based on importance, e.g., a first part might represent more significant bits in groups of bits representing pixel colors in a video frame, while a second part might represent the less significant bits in the groups. The more important part of the stream is error correction coded at a lower rate or using a more powerful coding technique (i.e., with more error correction coding) than is the less important part of the stream.

Abstract: A communication transaction or use case is broken down into constituent parts having different class of service (COS) requirements. The parts are matched to different links or channels having respective COS characteristics and communicated over the links or channels, and then aggregated at the receiver.
