Title:
SYSTEMS AND METHODS FOR SIGNALING NETWORK ABSTRACTION LAYER UNIT INFORMATION IN VIDEO CODING
Document Type and Number:
WIPO Patent Application WO/2020/255896
Kind Code:
A1
Abstract:
This disclosure relates to video coding and more particularly to a method of decoding network abstraction layer(NAL) unit information. The method of decoding NAL unit information comprises: receiving a NAL unit header syntax structure having two bytes; and decoding a first 1-bit syntax element, a second 1-bit syntax element and a 6-bit syntax element in the NAL unit header syntax structure, wherein a value of the first 1-bit syntax element is equal to zero, a value of the second 1-bit syntax element is equal to zero, and the 6-bit syntax element specifies an identifier of a layer to which a VCL NAL unit belongs or an identifier of a layer to which a non-VCL NAL unit applies.
