METHOD AND APPARATUS FOR SCALABLE MULTIMEDIA BROADCAST USING A MULTI-CARRIER COMMUNICATION SYSTEM

摘要

A wireless distribution system is provided where multiple carrier frequencies/channels are used to facilitate transmission of scalable multimedia content. Some carrier frequencies are assigned to carry base layer data for one or more program/content channels and some other carrier frequencies are assigned to carry data for one or more enhancement layers associated with the base layer data of one or more program/content channels. The enhancement layer carrier frequency may be shared among program/content channels transmitted over multiple different base layer carrier frequencies. Different numbers of enhancement layers and their bandwidth may correspond to different refinements of the multimedia content.
