Title:
METHOD AND APPARATUS OF CONSTRAINED LAYER-WISE VIDEO CODING
Document Type and Number:
WIPO Patent Application WO/2021/121313
Kind Code:
A1
Abstract:
Method and apparatus of video coding using a multi-layer prediction mode, are disclosed. According to one method, a bitstream is generated at an encoder side or received at a decoder side, where the bitstream corresponds to coded data of current video data in a current layer. The bitstream complies with a bitstream conformance requirement corresponding both the bit depth values for the current layer and the reference layer being the same and the chroma format index values for the current layer and the reference layer being the same. The current video data in the current layer is then encoded or decoded by utilizing reference video data in the reference layer.
