Method and apparatus for transmitting and receiving broadcast data using outer-coding in a mobile communication system
First Claim
1. A method for providing a broadcast service in a mobile communication system which outer-codes frames for a plurality of broadcast services, the method comprising the steps of:
- generating a broadcast parameter message comprising information indicating at least one sub-buffer in which frames for a requested broadcast service are stored; and
transmitting the broadcast parameter message.

Abstract
A method and apparatus for transmitting and receiving a broadcast service in a mobile communication system which outer-codes frames for a plurality of broadcast services and Time Domain Multiplex (TDM)-transmits the outer-coded frames. A transmitter transmits a broadcast parameter message comprising information indicating a specific sub-buffer in which respective broadcast services are stored. A receiver for receiving the broadcast parameter message from the transmitter, and maps the sub-buffer to a corresponding sub-block mask based on the broadcast parameter message. The transmitter TDM-transmits the frames for the plurality of broadcast services per sub-block. The receiver selectively receives frames for a desired broadcast service using the sub-block mask and decodes the selectively received frames.
