Question: Which of the following media decoder types is EXCLUSIVE to MBMS Download delivery, rather than being common to both MBMS Download and Streaming delivery?
Option 1: Speech Media Decoders
Option 2: Other Media Decoders (excluding Speech, Audio, Video, Timed Text, and Scene description)
Option 3: Video Media Decoders
Option 4: Audio Media Decoders
Explanation: According to the specifications for MBMS (Multimedia Broadcast/Multicast Service), media decoders for Speech, Audio, Video, Timed Text, and Scene description are utilized in both MBMS Download and Streaming delivery methods. In contrast, "Other Media Decoders" (implying those beyond the explicitly listed types) are specifically designated for use in MBMS Download delivery only, distinguishing them from the more universally applied decoder types. This highlights the tailored approach to media handling based on the delivery mechanism within MBMS.
