A multimedia distribution system is disclosed. The distribution system
includes a transmitter unit that distributes content from a content
provider to one or more wireless subscriber units. The transmitter unit
includes a decoder configured to determine whether a plurality of
incoming packets include one or more erasures, a transmitter configured
to transmit the packets to a receiving unit, and an error detection code
generator configured to generate an error detection code for each of the
packets transmitted to the receiver unit, the error detection code being
modified for each of the erased packets so that the receiver unit will be
able to identify the erased packets.
