Question: In MBMS, how is the FEC Object Transmission Information primarily conveyed to receivers?
Option 1: Through periodic in-band signaling within the broadcast stream.
Option 2: Exclusively through SDP (Session Description Protocol) messages.
Option 3: Via a dedicated control channel separate from the data stream.
Option 4: Embedded within the FEC Scheme Specific Information of each packet.
Explanation: The correct answer is Option 2 because, according to specifications, the FEC Object Transmission Information is only communicated in SDP messages. This method ensures receivers can properly configure themselves for FEC decoding without relying on in-stream signaling or separate control channels, simplifying receiver implementation and ensuring consistency across MBMS deployments.
