Attribute Support In Point Cloud Coding

A method implemented by a video encoder, the method comprising:

• encoding, by a processor of the video encoder, a sequence of point cloud coding (PCC) frames into a bitstream, wherein the sequence of PCC frames represent a plurality of PCC attributes including geometry, texture, and one or more of reflectance, transparency, and normal, and wherein each PCC frame is encoded in a number of PCC network abstraction layer (NAL) units;
• encoding, by the processor, an indication for each of the PCC NAL units that indicates whether each of the PCC NAL units belongs to a corresponding one of the PCC attributes, and to which of the PCC attributes the PCC NAL unit belongs when the PCC NAL unit belongs to the corresponding PCC attribute;
• and
• transmitting, by a transmitter of the video encoder, the bitstream toward a video decoder.

A video coding device comprising:

• a receiver configured to receive a bitstream comprising a plurality of coded sequences of point cloud coding (PCC) frames, wherein the plurality of coded sequences of PCC frames represent a plurality of PCC attributes including geometry, texture, and one or more of reflectance, transparency, and normal, and wherein each coded PCC frame is represented by one or more PCC network abstraction layer (NAL) units;
• and
• a processor configured to:
• parse the bitstream to obtain an indication for each of the PCC NAL units that indicates whether each of the PCC NAL units belongs to a corresponding one of the PCC attributes, and to which of the PCC attributes the PCC NAL unit belongs when the PCC NAL unit belongs to the corresponding PCC attribute;
• and
• decode the bitstream based on the indications.
