Recent innovation in video-based applications such as tile-based streaming of omnidirectional videos has been leveraging HEVC tiles. Although proven to be possible, these applications suffer from complex implementation and low performances due to limitations of the design of HEVC tiles: rigid grid structure, absolute tile position, tile position at low-level in the bitstream, absence of high-level syntax element for tile detection, non-trivial encoding constraints, etc. To better support these innovations with VVC, it is proposed to define two types of tiles:
