A method and apparatus for staggercasting includes encoding a set of signals representing content such that each encoded signal, alone or in combination with other encoded signals, is capable of being decoded to produce a corresponding decoded signal. Each decoded signal has a reproduced quality which different from the reproduced quality of all the other decoded signals. A composite signal is generated including the set of encoded signals. The encoded signal corresponding to a lowest quality decoded signal is undelayed. The other encoded signals are delayed by different amounts such that the higher the quality of the corresponding decoded signal, the longer the delay period. The set of encoded signals is extracted from the composite signal, and errors in the set of extracted encoded signals detected. A subset of available extracted encoded signals which are not erroneous is produced. A content representative signal at the highest quality possible is decoded from the subset of available extracted encoded signals. |
