Abstract
Method and apparatus for providing broadcast overhead information interleaved with a broadcast session in a transmission on a broadcast channel of a wireless communication system. In one embodiment, the information is stored at the receiver to provide quick updating when a user changes to an alternate broadcast channel. In one embodiment, the content server provides an identifier SDP_ID to distinguish among sets of protocol options description sets.
Claims51
In a wireless communication system supporting a broadcast service, a method comprising:
- transmitting a broadcast session on a broadcast transmission channel, wherein the broadcast transmission channel is a physical channel;
- and
- transmitting broadcast overhead information for the broadcast session in-band with the broadcast session on the broadcast transmission channel, wherein the broadcast overhead information includes a session description protocol (SDP) message that provides information including physical layer formatting information for decoding the physical channel carrying the broadcast session to a receiver for processing the received broadcast session on the received broadcast channel, and wherein the physical layer formatting information includes a Walsh code for decoding the physical channel.
A method of transmitting a communication signal on a carrier wave, the method comprising:
- transmitting a broadcast session portion;
- and
- transmitting a session description protocol message (SDP message) for the broadcast session portion in-band with the broadcast session portion, wherein the SDP provides information including physical layer formatting information for decoding a physical channel carrying the broadcast session portion to a receiver for processing the received broadcast session portion, and wherein the physical layer formatting information includes a Walsh code for decoding the physical channel.
In a wireless communication system supporting a broadcast service, a method comprising:
- receiving a session description protocol (SDP) message for a broadcast session in-band corresponding to the broadcast session on a broadcast channel, wherein the broadcast channel is a physical channel, wherein the SDP message provides information including physical layer formatting information for decoding the physical channel carrying the broadcast session to a receiver for processing the received broadcast session on the received broadcast channel, and wherein the physical layer formatting information includes a Walsh code for decoding the physical channel;
- accessing the broadcast session on the broadcast channel;
- and
- processing the received broadcast session using the SDP message.

A wireless apparatus, comprising:
- means for receiving a broadcast service parameter message corresponding to a broadcast session on a broadcast transmission channel, wherein the broadcast transmission channel is a physical channel;
- means for receiving an SDP message for a broadcast session in-band corresponding to the broadcast session in a broadcast stream, wherein the SDP message provides information including physical layer formatting information for decoding the physical channel carrying the broadcast session to a receiver for processing the received broadcast session on the received broadcast stream, and wherein the physical layer formatting information includes a Walsh code for decoding the physical channel;
- and
- means for processing the received broadcast session using the SDP.
1 more element
A method for indicating broadcast session protocol, comprising:
- multiplexing information identifying a broadcast session protocol for a broadcast session in-band with a content of the broadcast session to provide a broadcast stream;
- and
- transmitting the broadcast stream on a broadcast transmission channel, wherein the broadcast transmission channel is a physical channel, wherein the information identifying the broadcast session protocol includes a session description protocol (SDP) message that provides information including physical layer formatting information for decoding the physical channel carrying the broadcast session to a receiver for processing the received broadcast session on the received broadcast channel, and wherein the physical layer formatting information includes a Walsh code for decoding the physical channel.
A method indicating broadcast session protocol, comprising:
- receiving a broadcast stream;
- determining information for a broadcast session received in-band with the broadcast stream, the information includes a session description protocol (SDP) message including physical layer formatting information for decoding a physical channel carrying the broadcast session in the broadcast stream, wherein the physical layer formatting information includes a broadcast session protocol in accordance with the received broadcast stream, and wherein the physical layer formatting information includes a Walsh code for decoding the physical channel;
- and
- processing the received broadcast session on the received broadcast stream in accordance with the determined information if a receiving station contains the broadcast session protocol.
1 more element
A method for indicating broadcast session protocol, comprising:
- multiplexing information identifying a broadcast session protocol for a broadcast session in-band with a content of the broadcast session to provide a broadcast stream;
- and
- providing the broadcast stream for transmission, wherein the information identifying the broadcast session protocol includes a session description protocol (SDP) message that provides information including physical layer formatting information for decoding a physical channel carrying the broadcast session to a receiver for processing the received broadcast session on the received broadcast stream, and wherein the physical layer formatting information includes a Walsh code for decoding the physical channel.
A method for indicating a broadcast session protocol, comprising:
- receiving a broadcast stream;
- determining information element for a broadcast session is received in-band with the received broadcast stream, the information element includes a session description protocol (SDP) message including physical layer formatting information for decoding a physical channel carrying the broadcast session in the received broadcast stream for the received broadcast session, and wherein the physical layer formatting information includes a Walsh code for decoding the physical channel;
- and
- processing the received broadcast stream in accordance with the determined information element.
1 more element
A method for indicating broadcast session protocol, comprising:
- multiplexing information for a broadcast session in-band with a broadcast stream, the information including a session description protocol (SDP) message including physical layer formatting information for decoding a physical channel carrying the broadcast session for a receiver for processing a broadcast transmission channel with a content of the broadcast session to produce the broadcast stream;
- and
- transmitting the broadcast stream on the broadcast transmission channel, wherein the physical channel is the broadcast transmission channel, and wherein the physical layer formatting information includes a Walsh code for decoding the physical channel.
A method indicating broadcast protocol options, comprising:
- receiving a broadcast stream;
- determining information for a broadcast session received in-band with the broadcast stream, the information including a session description protocol (SDP) message including physical layer formatting information for decoding a physical channel carrying the broadcast session to a receiver in the broadcast stream for processing the received broadcast session, and wherein the physical layer formatting information includes a Walsh code for decoding the physical channel;
- and
- processing the received broadcast stream in accordance with the determined information for the received broadcast session.
