Question: In the context of Transparent end-to-end Packet-switched Streaming Service (PSS), what is the primary purpose of the CP protocol in conjunction with P over UDP/IP for real-time or streaming data transmission?
Option 1: To encapsulate encoded media into packets with media-specific payload formats.
Option 2: To provide encryption for secure data transmission over public networks.
Option 3: To manage Quality of Service (QoS) parameters for prioritizing traffic.
Option 4: To offer feedback about the transmission quality of the streaming data.
Explanation: The CP protocol is utilized in conjunction with P over UDP/IP to provide feedback on the transmission quality of the real-time or streaming data. This feedback mechanism is crucial for adjusting transmission parameters to maintain optimal stream quality, highlighting its role in practical telecom scenarios related to media transfer and session management.
