Abstract
Embodiments herein provide mechanisms for a receiving device to indicate to a transmitting device viewport information to indicate a region of interest for point cloud video content. For example, the receiving device may transmit a real-time transport control protocol (RTCP) feedback message that includes the viewport information. The viewport information includes an indication of a reference point for the region of interest. The receiving device may receive, from the transmitting device, the point cloud video for the region of interest based on the viewport information. Other embodiments may be described and claimed.
Claims23
One or more non-transitory, computer-readable media (NTCRM) having instructions, stored thereon, that when executed by one or more processors of a first UE, cause the first UE to:
- transmit, from the first UE to a second UE that is to capture point cloud video, a real-time transport control protocol (RTCP) feedback message that includes viewport information to indicate a region of interest, wherein the viewport information in the RTCP feedback message includes:
- an indication of a center of a sphere, wherein the center of the sphere is a reference point for the region of interest;
- and
- an indication of the region of interest as a portion of the sphere, wherein the indication of the region of interest is provided with respect to the reference point;
- and
- receive, by the first UE from the second UE, the point cloud video for the region of interest based on the viewport information.
One or more non-transitory, computer-readable media (NTCRM) having instructions, stored thereon, that when executed by one or more processors of a first UE, cause the first UE to:
- receive, by the first UE from a second UE, a real-time transport control protocol (RTCP) feedback message that includes viewport information to indicate a region of interest associated with point cloud video content, wherein the viewport information in the RTCP feedback message includes:
- an indication of a point in a three-dimensional volume, wherein the point in the three-dimensional volume is a reference point for the region of interest;
- and
- an indication of the region of interest as a portion of the three-dimensional volume, wherein the indication of the region of interest is provided with respect to the reference point;
- and
- transmit, from the first UE to the second UE, the point cloud video for the region of interest based on the viewport information.
An apparatus to be implemented in a first user equipment (UE), the apparatus comprising:
- a multimedia telephony services over Internet Protocol multimedia subsystem (MTSI) client to:
- transmit, from the first UE to a second UE that is to capture point cloud video, a real-time transport control protocol (RTCP) feedback message that includes viewport information to indicate a region of interest, wherein the viewport information in the RTCP feedback message includes:
- an indication of a center of a sphere, wherein the center of the sphere is a reference point for the region of interest;
- and
- an indication of the region of interest as a portion of the sphere, wherein the indication of the region of interest is provided with respect to the reference point;
- and
- receive, by the first UE from the second UE, the point cloud video for the region of interest based on the viewport information;
- and
- processor circuitry to render the received point cloud video.
