Abstract
A and method encode a view area within a current image frame of a video into an encoded video area frame. The view area is a respective subarea of each image frame, each image frame comprising first and second image portions, and between previous and current image frames, the view area moves across a boundary between the first and second image portions. First and second encoders are encode image data of the first and second image portions, respectively. First, second and third portions of the view area are identified based on their respective location in the previous and current image frames. Image data of the first and third portions are inter-coded as first and third encoded slices/tiles. Image data of the second portion of the view area in the current image frame are intra-coded as a second encoded slice/tile. The encoded slices/tiles are merged into the encoded video area frame.
