Abstract
The present invention comprises aggregating a plurality of physical channels to a single logical channel, a scalable virtual channel (SVC). This may be implemented in a point to multipoint communications system. The present invention enables a variety of receivers, some receivers being able to receive only one physical channel, and other receivers being able to receive a plurality of physical channels as a SVC, with at least one same channel being used for both types of receivers.
