Title:

ROBUST MODE STAGGERCASTING

Document Type and Number:

WIPO Patent Application WO2004070986

Kind Code:

A3

Abstract:

A method and apparatus for staggercasting, encodes a first signal representing content and encodes a second signal representing the content using encoding relatively more robust than the encoding of the first encoded content representative signal. A composite signal including at least the first and second encoded signals is generated, in which one of the first and second encoded signals is delayed with respect to the other encoded signal. If an error is detected in the composite signal, then the undelayed encoded signal is decoded to reproduce the content. Otherwise, the delayed encoded signal is decoded to reproduce the content.
