fast channel switching for staggered diffusion in robust mode

摘要

"FAST CHANNEL EXCHANGE BY STABILIZED DIFFUSION IN ROBUST MODE". In accordance with the principles of the present invention, a method and apparatus for staggered broadcasting of a plurality of content representative signals includes encoding a first and a second signal each representing a plurality of content representative signals. A composite signal is generated comprising the plurality of the first and second coded signals. In the composite signal, each respective second coded signal is delayed relative to the corresponding first coded signal. The first and second coded signals representing that selected one of the content representative signals are extracted to reproduce the selected content representative signal. The first extracted coded signal is decoded, if an error is detected in the second extracted coded signal, otherwise the second extracted coded signal is decoded. When a different representative signal is recently selected, the first extracted coded signal is decoded until the second delayed extracted coded signal becomes available.
