Abstract
The profile_tier_level syntax structure of a High Efficiency Video Coding (HEVC) syntax structure is updated to provide more flexibility for use in the vps_extension( ) syntax structure for use in each layer or operating point. A new flag ‘LevelPresentFlag’ is added in profile_tier_level syntax structure to support the variance of Level parameters separately from the Profile/Tier Parameter. The update to the profile_tier_level syntax structure provides flexibility in selecting profile_tier and level parameters for HEVC selections in scalable video coding, multi-view coding and 3D video coding areas.
