Question: What is the primary purpose of modifying the H.324 standard to create 3G-324M terminals in 3GPP networks?
Option 1: To enhance security features for multimedia transmissions
Option 2: To enable cost-effective, high-quality terminals for circuit-switched multimedia telephony services
Option 3: To introduce support for packet-switched communications
Option 4: To reduce the complexity of video codec processing
Explanation: The modification of H.324 to create 3G-324M terminals is primarily aimed at achieving a balance between cost-effectiveness and high-quality performance, specifically tailored for circuit-switched multimedia telephony services within 3GPP networks. This ensures that terminals (3G-324M) can provide efficient and superior quality multimedia experiences without incurring excessive costs, aligning with the needs of both service providers and end-users.
