Question: What is the primary purpose of the FEC encoding scheme defined by FEC Encoding ID 1 in the context of MBMS (Multimedia Broadcast/Multicast Service)?
Option 1: To enhance video codec efficiency for multimedia streaming
Option 2: To provide end-to-end encryption for secure data transfer
Option 3: To implement forward error correction for reliable download delivery
Option 4: To manage Quality of Service (QoS) parameters in wireless networks
Explanation: The correct answer, Option 3, is the primary purpose of the FEC encoding scheme defined by FEC Encoding ID 1. This is because the FEC (Forward Error Correction) scheme is specifically designed to correct errors that occur during data transmission, thereby ensuring reliable download delivery in MBMS services. The other options are not directly related to the main function of FEC Encoding ID 1 as described. Option 1 pertains to video codec efficiency, Option 2 refers to encryption which is a different aspect of security, and Option 4 deals with QoS management, all of which are outside the scope of this specific FEC scheme's purpose.
