Question: What profiles of the 3GPP file format must an MBMS (Multimedia Broadcast/Multicast Service) client support for compliant operation?
Option 1: Only the Extended Presentation Profile
Option 2: Either the Basic Profile or the Extended Presentation Profile
Option 3: Additional Custom Profiles defined by the Network Operator
Option 4: Both the Basic Profile and the Extended Presentation Profile
Explanation: To ensure compatibility and seamless delivery of multimedia content, an MBMS client is mandated to support both the foundational Basic Profile (offering fundamental functionality) and the Extended Presentation Profile (providing enhanced features for richer media experiences). This dual-support requirement enables clients to handle a wide range of content types effectively over MBMS, aligning with the 3GPP's goal of standardized, interoperable multimedia services.
