Title:
METHOD AND APPARATUS FOR GENERATING AND ENCODING PROJECTION-BASED FRAME WITH 360-DEGREE CONTENT REPRESENTED IN PROJECTION FACES PACKED IN SEGMENTED SPHERE PROJECTION LAYOUT
Document Type and Number:
WIPO Patent Application WO/2018/171608
Kind Code:
A1
Abstract:
A video processing method includes receiving an omnidirectional content corresponding to a sphere, generating a projection-based frame according to at least the omnidirectional content and a segmented sphere projection (SSP) format, and encoding, by a video encoder, the projection-based frame to generate a part of a bitstream. The projection-based frame has a 360-degree content represented by a first circular projection face, a second circular projection face, and at least one rectangular projection face packed in an SSP layout. A north polar region of the sphere is mapped onto the first circular projection face. A south polar region of the sphere is mapped onto the second circular projection face. At least one non-polar ring-shaped segment between the north polar region and the south polar region of the sphere is mapped onto said at least one rectangular projection face.
