Published: with international search report (Art. 21(3)) (54) Title: 360-DEGREE VIDEO CODING USING FACE CONTINUITIES (57) : A coding device (e.g., that may be or may include encoder and/ or decoder) may receive a frame-packed picture of 380-degree video. The cod- ing device may identify a face in the frame-packed picture that the current block belongs to. The coding device may determine that a current block is located at a boundary of the face that the current block belongs to. The coding device may identify multiple spherical neighboring blocks of the current block. The coding device may identify a cross-face boundary neighboring block. The cod- ing device may identify a block in the frame-packed picture that corresponds to the cross-face boundary neighboring block. The coding device may determine whether to use the identified block to code the current block based on avail- ability of the identified block. The coding device may code the current block based on the determination to use the identified block.
