Question: In MBMS (Multimedia Broadcast/Multicast Service) download delivery, how are the media type and format list specified in the Session Description Protocol (SDP) "m=" line?
Option 1: <media> = 'video', <fmt> = '1' for all video content
Option 2: <media> = 'application', <fmt> = '0' for standardized MBMS downloads
Option 3: <media> = 'audio', <fmt> = 'dynamic' based on the audio codec used
Option 4: <media> = 'text', <fmt> = 'variable' depending on the text format
Explanation: In the context of MBMS download delivery, standardizing the media type and format list in SDP is crucial for interoperability. Setting <media> to 'application' and <fmt> to '0' ensures consistency across all MBMS downloads, simplifying client-side handling without needing to parse variable formats or media types.
