- H04N 19/597: specially adapted for multi-view video sequence encoding
- H04N 19/30: using hierarchical techniques, e.g. scalability (H04N19/63 takes precedence)
- H04N 19/70: characterised by syntax aspects related to video coding, e.g. related to compression standards

## 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.
