FAST CHANNEL SWITCHING IN MULTIMEDIA BROADCAST SYSTEM

PROBLEM TO BE SOLVED: To enable a wireless communications device to rapidly acquire media logical channels and access any information (e.g., a decryption key) required to receive the service.SOLUTION: A wireless broadcast system includes a transmitter for broadcasting to a wireless communications device. The transmitter receives a plurality of streams on a logical channel, in which one of the streams contains signaling. The transmitter arranges the streams such that the stream containing the signaling is broadcasted after the other streams on the logical channel. The wireless communications device receives the streams broadcasted on a logical channel broadcasted in a frame, and acquires the logical channel during the broadcast of the frame in response to a prompt received during the broadcast of the same frame.
