Question: For a 3GPP PSS client supporting 3D/VR audio in DASH services, what is the recommended compliance requirement for file format signalling and encapsulation?
Option 1: MPEG-DASH Media Presentation Description (MPD) alone
Option 2: OMAF 2D Audio Enhanced Media Profile Receiver requirements
Option 3: OMAF 3D Audio Baseline Media Profile Receiver requirements for Virtual Reality (VR) profiles
Option 4: H.264/AVC Video Coding Standard for signalling and encapsulation
Explanation: To ensure compatibility and proper handling of 3D/VR audio content in DASH services, the 3GPP PSS client should adhere to specific standards for both signalling and encapsulation. The OMAF 3D Audio Baseline Media Profile Receiver requirements provide necessary guidelines for effectively managing 3D/VR audio file formats, ensuring a seamless and immersive user experience.
