Abstract: An apparatus comprises an encoder configured to obtain point clouds, generate a first field that implements prediction type signaling of the point clouds, generate a second field that implements temporal order signaling of the point clouds, and encode the first field and the second field into an encoded bitstream; and an output interface coupled to the encoder and configured to transmit the encoded bitstream. An apparatus comprises a receiver configured to receive an encoded bitstream; and a processor coupled to the encoded bitstream and configured to decode the encoded bitstream to obtain a first field and second field, wherein the first field implements prediction type signaling of point clouds, and wherein the second field implements temporal order signaling of the point clouds, and generate the point clouds based on the first field and the second field.
