Question: For an MBMS client supporting 360 VR video, which of the following receiver compliance is mandatory?
Option 1: Main H.265/HEVC Operation Point Receiver as per TS 26.118
Option 2: H.264/AVC Basic Operation Point Receiver as per TS 26.118
Option 3: Both H.264/AVC and H.265/HEVC Operation Point Receivers as per TS 26.118
Option 4: None of the above; compliance is entirely optional for MBMS clients with 360 VR video support
Explanation: According to the specifications, if an MBMS client supports 360 VR video, it shall (indicating a requirement) include a receiver that complies with the H.264/AVC Basic Operation Point Receiver requirements. In contrast, compliance with Main H.265/HEVC Operation Point Receiver is recommended (should) but not mandatory for 360 VR video support. Thus, the correct answer focuses on the mandatory aspect for 360 VR video support in MBMS clients.
