Question: In a Transparent end-to-end Packet-switched Streaming Service (PSS) as per 3GPP standards, how are servers mandated to multiplex the original and retransmission streams for retransmission payload format?
Option 1: Time-Division Multiplexing (TDM)
Option 2: Session-Multiplexing
Option 3: SSRC-Multiplexing (Synchronization Source Identifier Multiplexing)
Option 4: Frequency-Division Multiplexing (FDM)
Explanation: In the context of PSS, efficient management of original and retransmission streams is crucial. SSRC-Multiplexing is specifically mandated for servers because it allows for differentiation of the original stream and its retransmitted packets using the Synchronization Source Identifier (SSRC), ensuring clear identification and handling at the receiver end without confusing the streams, which is essential for maintaining stream integrity and facilitating proper reassembly or error correction.
