Method and apparatus for accessing and transferring point cloud content in 360-degree video environment

A method for receiving data related to content including an omnidirectional image and a point cloud object, the method comprising:

• receiving media data and metadata for the content including the omnidirectional image and the point cloud object;
• and
• rendering the content based on the received media data and the metadata,
• wherein the metadata comprises information for specifying sub-spaces of a bounding space which is located within a space corresponding to the omnidirectional image and contains the point cloud object inside the bounding space, and
• wherein the information for specifying the sub-spaces of the bounding space comprises information specifying whether the bounding space is uniformly divided into the sub-spaces.

An apparatus for transmitting data related to content including an omnidirectional image and a point cloud object, the apparatus comprising:

• a controller;
• and
• a memory storing instructions for operating the controller to:
• generate media data and metadata for the content including the omnidirectional image and the point cloud object, and
• transmit the generated media data and the generated metadata,
• wherein the metadata comprises information for specifying sub-spaces of a bounding space which is located within a space corresponding to the omnidirectional image and contains the point cloud object inside the bounding space, and
• wherein the information for specifying the sub-spaces of the bounding space comprises information specifying whether the bounding space is uniformly divided into the sub-spaces.
