Title:
VIDEO DECODING METHOD FOR DECODING BITSTREAM TO GENERATE PROJECTION-BASED FRAME WITH GUARD BAND TYPE SPECIFIED BY SYNTAX ELEMENT SIGNALING
Document Type and Number:
WIPO Patent Application WO/2021/136372
Kind Code:
A1
Abstract:
A video decoding method includes: decoding a part of a bitstream to generate a decoded frame, including parsing a syntax element from the bitstream. The decoded frame is a projection-based frame that includes at least one projection face and at least one guard band packed in a projection layout with padding, and at least a portion of a 360-degree content of a sphere is mapped to the at least one projection face via projection. The syntax element specifies a guard band type of the at least one guard band.
