Question: In an MBMS (Multimedia Broadcast/Multicast Service) scenario without bundling, what happens when a User Equipment (UE) switches to a new channel?
Option 1: The UE immediately starts processing the new video and audio streams simultaneously.
Option 2: The UE buffers the new channel for at least the minimum buffer time before processing.
Option 3: The UE drops the current stream and instantly switches to the new audio stream only.
Option 4: Channel switching is not supported when bundling is not used.
Explanation: In the absence of bundling, each channel in an MBMS setup is protected and handled separately. When a UE initiates a channel switch, to ensure seamless playback and prevent buffer underruns, the new channel's content must be buffered for at least the minimum required time (min-buffer-time) before the UE can start processing and rendering the new video and audio streams. This approach ensures that the UE has sufficient pre-loaded content to maintain continuous media playback during the switch.
