摘要： A method of operation of a video coding system includes: receiving a video bitstream as a serial bitstream; extracting a video syntax from the video bitstream; extracting a low delay flag, a network abstraction layer (NAL) hypothetical reference decode (HRD) parameters present flag, and a video coding layer (VCL) HRD parameters present flag from the video syntax extracting a HRD syntax from the video bitstream based on the low delay flag, the NAL HRD parameters present flag, and the VCL HRD parameters present flag; extracting a temporal layer from the video bitstream based on the video syntax having the HRD syntax; and forming a video stream based on the temporal layer for displaying on a device.

摘要： 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.

摘要： 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.

摘要： The VPS and vps_extension( ) syntax structures are updated with some cleanups for the HEVC Extensions in scalable video coding, multi-view coding and 3D video coding areas. In addition, four options of adding syntaxes to support mixed video sequences in various layers for the VPS extension are described.
