Assignee: DOLBY INTERNATIONAL AB
Field: Audio-visual technology (Electrical engineering)
Classification: CPC H | IPC H

Claim 8:
9. An MPEG-H 3D Audio decoder for processing position information indicative of an object position of an audio object, wherein the object position is usable for rendering of the audio object, the decoder comprising a processor and a memory coupled to the processor, wherein the processor is adapted to:
obtain listener orientation information indicative of an orientation of a listener's head, wherein the listener orientation information comprises information on a yaw, a pitch, and a roll of the listener's head;
obtain listener displacement information indicative of a displacement of the listener's head relative to a nominal listening position, via an MPEG-H 3D Audio decoder input interface;
determine the object position from the position information;
modify the object position based on the listener displacement information by applying a translation to the object position;
further modify the modified object position based on the listener orientation information, wherein when the listener displacement information is indicative of a displacement of the listener's head from the nominal listening position by a small positional displacement, the small positional displacement having an absolute value of 0.5 meter or less than 0.5 meter, wherein a distance between the audio object position and a listening position after displacement of the listener's head is equal to a distance between the modified audio object position and the nominal listening position; and
render the audio object to one or more real or virtual speakers in accordance with the further modified object position.
