Abstract
Aspects of the subject disclosure may include, for example, encoding a point cloud in a first frame of volumetric video in an octree format and identifying a first group of points of the point cloud, resulting in a first base layer including a base layer, a first enhancement layer and a second enhancement layer. Each layer includes different points from the point cloud, with the second enhancement layer including all points in each octet of leaf nodes in the octree format of the point cloud that are not in the base layer and the first enhancement layer. The first base layer of the point cloud is provided over a communication network to a media device and the first enhancement layer is also provided responsive to a determination of sufficient available bandwidth in the communication network. Other embodiments are disclosed.
