Field: Audio-visual technology (Electrical engineering)
Classification: CPC G  H | IPC G  H

Claim 16:
17. A video decoder apparatus comprising a processor configured to implement a method, comprising:
acquiring a video bitstream that includes an encoded video image that is a rectangular two-dimensional image comprising multiple regions of a panoramic image corresponding to a width W, a height H and a depth D in three-dimensional coordinates,
wherein the encoded video image has a width 2*W+D and a 2*H height and the multiple regions include a top left portion representing a down view rotated 180 degrees in a counter clockwise direction, a top middle portion representing a left view rotated 90 degrees clockwise, a top right portion representing an up view, a bottom left portion representing a front view, a bottom middle portion representing a right view and a bottom right portion representing a back view of the panoramic image,
wherein the down view, the left view, the up view, the front view, the right view, and the back view are views according to a coordinate system defined by x, y, and z axes,
wherein the down view and the up view represent views along the y axis where the down view has a lower y coordinate value than that of the up view,
wherein the left view and the right view represent views along the x axis where the left view has a lower x coordinate value than that of the right view, and
wherein the front view and the back view represent views along the z axis where the back view has a lower z coordinate value than that of the front view;

extracting neighboring information for the multiple regions;
performing, using the neighboring information, post-processing of a video image decoded from the video bitstream; and
generating a display image from the video image after the post-processing.
