Abstract
A method and Video-Based Point Cloud Compression (V-PCC) decoder for synchronization of decoded frames before point cloud reconstruction is provided. A V-PCC bit-stream which includes encoded frames associated with a point cloud sequence is received. Sub-streams of the received V-PCC bit-stream are decoded by a group of video decoders of the V-PCC decoder to generate V-PCC components, such as an attribute component, a geometry component, an occupancy map component, and an atlas component. A release of the attribute component, the geometry component, the occupancy map component, and the atlas component to the reconstruction unit is delayed based on a first output delay, a second output delay, a third output delay, and a fourth output delay, respectively. The delayed release synchronizes the attribute component, the geometry component, the occupancy map component, and the atlas component with each other before the reconstruction unit reconstructs a point cloud based on the V-PCC components.
