Abstract

Scene-based Audio is differentiated from Channel-based and Object-based Audio in that it represents a complete soundfield without requiring loudspeaker feeds or audio-objects with associated meta-data to recreate the soundfield during playback. Recent activity at MPEG, ATSC and DVB has seen proposals for the use of Higher-Order-Ambisonics (HOA) for Scene-based Audio. The many benefits of Scene-base Audio is countered by the bandwidth requirements as well the ability to transport the multitude of HOA coefficient channels through current day Television plants. In this paper, we report on research and standardization activities directed at solving these issues. These solutions enable the Television broadcast and delivery of both live-captured and artistically-created sound scenes using HOA.
