ABSTRACT:
A technique for fast common overhead services acquisition for MediaFLO™ mobile multimedia multicast system, wherein encoding overhead information symbol (OIS) information in a first burst of MLC of each superframe, OIS comprises control channel (CC) information and reserved flow data comprising primary flow data, service information data, notification flow data, configuration flow data, and presentation metadata; encoding padding in second MLC burst; encoding parity bytes in third and fourth MLC bursts; encoding primary flow data in final MLC burst per superframe; encoding the remaining reserved flow data at the end of superframe; transmitting wireless data stream comprising first MLC at ½ forward error correction (FEC) rate and receiving it in receiver; determining a correctness of CC information by checking cyclic redundancy check (CRC) bits at the end of each received data packet; and transmitter sending size wise remainder of reserved flows at the end of superframe.
