Question: In Multimedia Broadcast/Multicast Service (MBMS), how is the FEC Repair Stream, used for transporting repair data in streaming delivery, typically described and referenced?
Option 1: Via a dedicated XML file linked to the Media Presentation Description (MPD)
Option 2: Through an SDP (Session Description Protocol) file referenced by the bundleDescription element
Option 3: By an inline description within the User Service Bundle Description metadata fragment
Option 4: Using a separate, non-standard metadata file specific to FEC configurations
Explanation: In MBMS, for efficient error correction in streaming, the FEC Repair Stream is described using standardized protocols. The correct answer highlights the use of an SDP file (a widely adopted standard for describing multimedia sessions, including those requiring FEC), facilitating a clear, universally understood description of the repair stream for interoperability and streamlined error correction across different MBMS implementations.
