Abstract
When encoding and transmitting video data comprising regions of interest, different usages of the regions of interest implicate different kinds of combination of region of interest at decoding. By studying the different impacts of the encoding mechanisms depending on other set of tiles data on the different kind of combination, it is possible to define a plurality of tile set coding dependency levels. Each tile set coding dependency level is linked to a set of constraints on encoding. These set of constraints have different impacts on the possibilities allowed when combining the different regions of interest. It is therefore possible, based on a desired usage, to select an encoding with minimal restrictions, as defined by a given tile coding dependency level, compatible with the desired usage. Accordingly, the encoding efficiency is improved, for a given usage, compared to a solution where a complete tile independency solution is used.
