Abstract
A method for decoding a bitstream by an apparatus, includes obtaining a decoded audio signal and metadata from the bitstream, the metadata comprising scene orientation information; and rendering the decoded audio signal based on the scene orientation information, wherein the scene orientation information is information for a direction of a video scene related to the decoded audio signal.
Claims10
A method for decoding a bitstream by an apparatus, the method comprising:
- obtaining an audio signal and metadata from the bitstream, the metadata comprising object metadata and information for indicating whether scene orientation information is present in the bitstream;
- receiving external control information including environmental setup information and element interaction information;
- modifying the object metadata based on the external control information;
- rendering the audio signal based on the modified object metadata;
- and
- rendering the rendered audio signal based on the scene orientation information,
- wherein the scene orientation information is information for an orientation of a video scene related to the audio signal,
- wherein the environmental setup information includes rendering type information for selecting one of a loudspeaker rendering and a binaural rendering and setup information indicating whether another output device is to be connected, and
- wherein the element interaction information includes interaction signature information, zoom area information, and user interaction mode information.
