Question: What is a primary advantage of using Partial Channel Bundling in Multimedia Broadcast/Multicast Service (MBMS) for combining video and audio streams?
Option 1: Reduced terminal processing with retained fast channel switching, leveraging audio's lower bitrate.
Option 2: Increased overall bitrate to accommodate more video streams simultaneously.
Option 3: Elimination of the need for rebuffering when switching between different video streams.
Option 4: Mandatory bundling of all available audio and video channels to a single bearer.
Explanation: Partial Channel Bundling is beneficial because it strikes a balance between reducing the processing load on the terminal (by not requiring full bundling) and maintaining swift channel switching capabilities, particularly advantageous for audio streams due to their significantly lower bitrate compared to video. This approach enhances user experience without overwhelming the terminal's resources.
