Abstract
Various embodiments of the present disclosure relate to a device and a method for processing point cloud data on the basis of PCC technology in a multimedia system. To this end, a bit stream according to point cloud compression may be generated, and the bit stream may be divided to generate access units by a plurality of type-specific data elements. The plurality of data elements may include at least one layer-specific shape data, at least one layer-specific texture data, auxiliary patch information, and occupancy information. The size of each of the plurality of access units may match a maximum transmission unit in a network.

A method for processing point cloud data in an electronic device, the method comprising:
- generating a bitstream according to point cloud compression (PCC);
- dividing the bitstream into a plurality of type-specific data components;
- and
- generating a plurality of access units (AUs) based on the plurality of type-specific data components by encapsulating the plurality of type-specific data components into a network abstraction layer, NAL, unit, included in a payload of the AU,
- wherein the plurality of type-specific data components comprise at least one layer-specific geometry data, at least one layer-specific texture data, auxiliary patch information, and occupancy (map) information,
- wherein the each of the plurality of AUs comprises a header and a payload, and
- wherein a size of each of the plurality of AUs matches a maximum transmission unit (MTU) in a network.
An electronic device for processing point cloud data, the electronic device comprising:
- a transceiver;
- and
- at least one processor connected to the transceiver,
- wherein the at least one processor is configured to:
- generate a bitstream according to point cloud compression (PCC), and
- dividing the bitstream into a plurality of type-specific data components, and
- generate a plurality of access units (AUs) based on the plurality of type-specific data components by encapsulating the plurality of type-specific data components into a network abstraction layer, NAL, unit, included in a payload of the AU,
- wherein the plurality of type-specific data components comprise at least one layer-specific geometry data, at least one layer-specific texture data, auxiliary patch information, and occupancy (map) information,
