Question: For a PSS (Packet-switched Streaming Service) client supporting 3D/VR audio, what is the recommended compliance standard for its receiver?
Option 1: ITU-T G.719 Audio Codec Requirements
Option 2: ETSI TS 101 154 AAC Audio Decoder Requirements
Option 3: 3GPP MPEG-H Audio Operation Point Receiver requirements for Virtual Reality (VR) profiles
Option 4: DVB-DASH (Dynamic Adaptive Streaming over HTTP) Audio Profile
Explanation: For a PSS client to support immersive experiences like 3D/VR audio, adhering to specific audio standards is crucial. The 3GPP MPEG-H Audio Operation Point Receiver requirements for VR profiles ensure compatibility and optimal performance for advanced audio formats in telecom domain streaming applications, making it the most appropriate choice for a PSS client supporting 3D/VR audio.
