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.

Claim (Index 14):
A client device for receiving data corresponding to a video sequence, from a server device, the client device comprising:\n a transmitter for transmitting to the server device at least one request message for requesting at least a spatial part of the video sequence, each of a plurality of frames of the video sequence being divided into spatial parts; and a receiver for receiving from the server device video data corresponding to the requested at least one spatial part of the video sequence; wherein the client device further comprises: means for receiving additional data from the server device, for signaling at least one spatial part coding dependency level associated to the requested spatial part of the video sequence; each spatial part coding dependency level being associated to encoding constraints used for encoding the requested spatial part of the video sequence; each spatial part coding dependency level being related to the decoding context of the spatial part when decoded at a decoding unit.
