摘要:
A method and apparatus for staggercasting to a mobile receiver, includes encoding a first signal representing content at a first quality and encoding a second signal representing the content at a second quality different than the first quality. A composite signal comprising the first and second encoded signals, wherein the first encoded signal is delayed with respect to the second encoded signal, is broadcast. The broadcast composite signal receiving at the mobile receiver where the received encoded signal having the lower quality is extracted from the received composite signal and the extracted encoded signal is decoded.
