Abstract
A method comprises obtaining media content associated with a first viewpoint and a second viewpoint, wherein a first position of the first viewpoint is static and a second position of the second viewpoint is dynamic; generating a first VWPT descriptor based on the media content and describing the first viewpoint; generating a second VWPT descriptor based on the media content and describing the second viewpoint; generating an MPD comprising the first VWPT descriptor and the second VWPT descriptor; and transmitting the MPD.
Claims20
A method comprising:
- obtaining, by a coding device, media content associated with a viewpoint;
- generating, by the coding device, a viewpoint information (VWPT) descriptor based on the media content, wherein the VWPT descriptor comprises a value indicating whether a position of the viewpoint is static and whether the position of the viewpoint is dynamic;
- generating, by the coding device, a media presentation description (MPD) comprising the VWPT descriptor at an adaptation set level of the MPD, wherein no VWPT descriptor is present at any level of the MPD other than the adaptation set level;
- and
- transmitting, by the coding device, the MPD.

A coding device comprising:
- a memory configured to store instructions;
- and
- a processor coupled to the memory and configured to execute the instructions to cause the coding device to:
- obtain media content associated with a viewpoint;
- generate a viewpoint information (VWPT) descriptor based on the media content, wherein the VWPT descriptor comprises a value indicating whether a position of the viewpoint is static and whether the position of the viewpoint is dynamic;
- generate a media presentation description (MPD) comprising the VWPT descriptor at an adaptation set level of the MPD, wherein no VWPT descriptor is present at any level of the MPD other than the adaptation set level;
- and
- transmit the MPD.
