Claim:
A method of enhancing stream layer transmission for a mobile multimedia multicast system comprising a transmitter and a receiver, said method comprising: sending a plurality of multicast logical channels (MLCs) forming a data frame from said transmitter, wherein each MLC comprises multimedia data streams comprising a stream 0 data packet, a stream 1 data packet, a stream 2 data packet, and parity data bits, and wherein four data frames comprises a super-frame; switching, by said transmitter, an order of said multimedia data streams of said MLC transmitted by said transmitter; sending a signal to said receiver from said transmitter to specify a mode of transmission of said MLC, wherein said mode of transmission comprises an order of transmitting the data packets of said MLC; inserting, by said transmitter, a flag in control information transmitted in said stream 0 data packets in said MLC; receiving, at said receiver, said flag; decoding, by said receiver, said flag to determine said mode of transmission; and performing, by said receiver, a cyclic redundancy check (CRC) of said stream 0 data packet.
