Abstract
A wireless broadcast system is disclosed. The wireless broadcast system includes a transmitter for broadcasting to a wireless communications device. The transmitter receives a plurality of streams on a logical channel, wherein one of the streams contains signaling. The transmitter arranges the streams such that the stream containing the signaling is broadcast after the other streams on the logical channel. The wireless communications device receives the streams broadcast on a logical channel broadcast 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.
Claims40
A wireless communications device, comprising:
- a receiver configured to receive a plurality of streams on a logical channel broadcast in a frame;
- and
- a processor configured to acquire the logical channel during the broadcast of the frame in response to a prompt received during the broadcast of the same frame.
A wireless communications device, comprising:
- means for receiving a plurality of streams on a logical channel broadcast in a frame;
- and
- means for acquiring the logical channel during the broadcast of the frame in response to a prompt received during the broadcast of the same frame.
A transmitter, comprising:
- a receiver configured to receive a plurality of streams on a logical channel, wherein one of the streams contains signaling;
- and
- a processor configured to arrange the streams such that the stream containing the signaling is broadcast after the other streams on the logical channel.
A transmitter, comprising:
- means for receiving a plurality of streams on a logical channel, wherein one of the streams contains signaling;
- and
- means for arranging the streams such that the stream containing the signaling is broadcast after the other streams on the logical channel.
A method of receiving a wireless broadcast, comprising:
- receiving a plurality of streams on a logical channel broadcast in a frame;
- and
- acquiring the logical channel during the broadcast of the frame in response to a prompt received during the broadcast of the same frame.
A method of broadcasting in a wireless medium, comprising:
- receiving a plurality of streams on a logical channel, wherein one of the streams contains signaling;
- and
- broadcasting the streams with the stream containing the signaling following the other streams on the logical channel.
A computer program product, comprising:
- computer-readable medium comprising code for causing a computer to acquire a logical channel having a plurality of streams broadcast in a frame, the code further causing the computer to acquire the logical channel during the broadcast of the frame in response to a prompt received during the broadcast of the same frame.
A computer program product, comprising:
- computer-readable medium comprising code to cause a computer to arrange a plurality of streams received on a logical channel for broadcasting, wherein one of the streams contains signaling, and wherein the code further causes the computer to arrange the streams such that the stream containing the signaling is broadcast after the other streams on the logical channel.
