Abstract
The HEVC VPS Syntax Structure is modified by re-ordering of some syntax parameters for the future HEVC Extensions in scalable video coding, multi-view coding and 3D video coding areas. This re-ordering enables external network devices such as middle-boxes to easily access of some of the useful parameters in VPS and its extension data that are able to be used for session negotiation and/or capability exchanges for better communication and system integration purposes.
