Abstract

Claims (36)

1 . At least one memory comprising instructions to cause at least one processor circuit to at least:

project point cloud data of a frame of an immersive video onto a plurality of planes associated respectively with a plurality of projection angles to determine a plurality of projected images;

encode the projected images in a bitstream; and

encode a syntax element in the bitstream, the syntax element to specify conformance information associated with reconstruction of the point cloud data from the bitstream, the conformance information based on a number of points to be created by the reconstruction of the point cloud data for the frame of the immersive video.

2 . The at least one memory of claim 1 , wherein the conformance information is associated with a conformance point.

3 . The at least one memory of claim 1 , wherein the syntax element is associated with at least one of a profile or a level.

4 . The at least one memory of claim 1 , wherein the syntax element is a first syntax element, and the instructions are to cause one or more of the at least one processor circuit to encode a second syntax element in the bitstream, the first syntax element associated with a profile, the second syntax element associated with a level.

5 . The at least one memory of claim 1 , wherein the instructions are to cause one or more of the at least one processor circuit to encode the syntax element in a message.

6 . The at least one memory of claim 5 , wherein the message is a supplemental enhancement information message.

7 . The at least one memory of claim 1 , wherein the point cloud data includes a plurality of points, respective ones of the points having a respective location, a respective color attribute and a respective reflectance attribute.

8 . An apparatus comprising:

memory;

instructions; and

at least one processor circuit to be programmed by the instructions to:

project point cloud data of a frame of an immersive video onto a plurality of planes associated respectively with a plurality of projection angles to determine a plurality of projected images;

encode the projected images in a bitstream; and

encode a syntax element in the bitstream, the syntax element to specify conformance information associated with reconstruction of the point cloud data from the bitstream, the conformance information based on a number of points to be created by the reconstruction of the point cloud data for the frame of the immersive video.

9 . The apparatus of claim 8 , wherein the conformance information is associated with a conformance point.

10 . The apparatus of claim 8 , wherein the syntax element is associated with at least one of a profile or a level.

11 . The apparatus of claim 8 , wherein the syntax element is a first syntax element, and one or more of the at least one processor circuit is to encode a second syntax element in the bitstream, the first syntax element associated with a profile, the second syntax element associated with a level.

12 . The apparatus of claim 8 , wherein one or more of the at least one processor circuit is to encode the syntax element in a message.

13 . The apparatus of claim 12 , wherein the message is a supplemental enhancement information message.

14 . The apparatus of claim 8 , wherein the point cloud data includes a point, the point having a location, a color attribute and a reflectance attribute.

15 . A system comprising:

memory;

instructions;

at least one processor circuit to be programmed based on the instructions to:

project point cloud data of a frame of an immersive video onto a plurality of planes associated respectively with a plurality of projection angles to determine a plurality of projected images;

encode the projected images in a bitstream; and

encode a syntax element in the bitstream, the syntax element to specify conformance information associated with reconstruction of the point cloud data from the bitstream, the conformance information based on a number of points to be created by the reconstruction of the point cloud data for the frame of the immersive video; and

network interface circuitry to transmit the bitstream.

16 . The system of claim 15 , wherein the conformance information is associated with a conformance point.

17 . The system of claim 15 , wherein the syntax element is a first syntax element, and one or more of the at least one processor circuit is to encode a second syntax element in the bitstream, the first syntax element associated with a profile, the second syntax element associated with a level.

18 . The system of claim 15 , wherein one or more of the at least one processor circuit is to encode the syntax element in a message.

19 . The system of claim 18 , wherein the message is a supplemental enhancement information message.

20 . The system of claim 15 , wherein the point cloud data includes a plurality of points, respective ones of the points having a respective location, a respective color attribute and a respective reflectance attribute.
