In the point cloud data transmission method according to the embodiments, a sample entry containing sequence parameter data for point cloud data may be included in a first track.
In the point cloud data reception method according to the embodiments, the first track including a sample entry containing sequence parameter data for point cloud data may be received.
In the point cloud data transmission method according to the embodiments, a sample entry containing patch parameter data for the point cloud data may be included in the first track.
In the point cloud data reception method according to the embodiments, the first track including a sample entry containing patch parameter data for the point cloud data may be received.
In this specification, the meaning of the first track is not limited to the name, and may refer to a V-PCC-related track containing the syntax described in this specification.
The point cloud data transmission/reception method/device according to the embodiments may process a track containing data for point cloud content, for example, V-PCC. The track may contain a sample entry. The sample entry may carry a sequence parameter set (SPS). Accordingly, the reception device according to the embodiments may efficiently decode the sample entry and/or parameter information based on the track.
Regarding the scheme for signaling the point cloud content, the V-PCC track may contain a sample entry. The sample entry may carry a patch parameter.
