VIDEO DECODING METHOD FOR DECODING PART OF BITSTREAM TO GENERATE PROJECTION-BASED FRAME WITH CONSTRAINED GUARD BAND SIZE, CONSTRAINED PROJECTION FACE SIZE, AND/OR CONSTRAINED PICTURE SIZE

A video decoding method includes decoding a part of a bitstream to generate a decoded frame. The decoded frame is a projection-based frame that comprises at least one projection face and at least one guard band packed in a projection layout. At least a portion of a 360-degree content of a sphere is...

Zusammenfassung:A video decoding method includes decoding a part of a bitstream to generate a decoded frame. The decoded frame is a projection-based frame that comprises at least one projection face and at least one guard band packed in a projection layout. At least a portion of a 360-degree content of a sphere is mapped to the at least one projection face via projection. The decoded frame is in a 4:2:0 chroma format or a 4:2:2 chroma format, and a guard band size of each of the at least one guard band is equal to an even number of luma samples.
