Panoramic streaming is a particular way of video streaming where an arbitrary Region-of-Interest (RoI) of high-spatial resolution videos is transmitted. It allows users to navigate interactively around the video and thus select anytime the portion of it they are interested in. The most basic approach consists of each user interacting with the system indicating the desired RoI. Then an encoder associated with each user encodes the desired RoI. However, such a system does not scale well. Instead, we consider tile based panoramic streaming, where users receive a set of tiles that match their RoI, and propose a low-complexity compressed domain video processing technique for tile based panoramic streaming using H.265/HEVC that generates a single video bitstream out of the selected tiles so that single hardware decoders can be used to decode the RoI video stream.
