Patent ID: 8126061

Claim:
A method for staggercasting to a mobile receiver, comprising the steps of: encoding a first signal representing content at a first quality; encoding a second signal representing the content at a second quality different than the first quality; delaying the first encoded signal; broadcasting a composite signal comprising the first delayed encoded signal and the second encoded signal; receiving the broadcast composite signal at the mobile receiver; and extracting the received encoded signal having the lower quality from the received composite signal and decoding the extracted encoded signal wherein the composite signal further comprises a signal carrying data identifying the second encoded signal in the composite signal; and the extracting step further comprises the steps of: extracting the identification data carrying signal from the composite signal; and extracting the signal identified by the identification data as the second encoded signal; and the extracting step further comprises the step of identifying the second encoded signal based on comparing a desired quality to the quality in the identification data.
