摘要： An encoder/decoder is described using enhanced signaling mechanisms SAO parameters. The various parameters are signaled in various ways according to different embodiments of the invention. In a first embodiment (embodiment A), SAO on / off is decoupled form SAO type coding, with SAO on / off flags being jointly encoded for all color components. The second embodiment (embodiment B), is similar to embodiment A, but modified for application to JCTVC-J0268. In a third embodiment separate signaling is provided for SAO on / off, SAO types BO and EO, and for BO and EO side information (classes or band position). Each of these enhanced SAO signaling mechanisms provide enhanced coding efficiency.

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 Paremeter. 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： A Flexible Band Offset (FBO) apparatus and method of performing Sample Adaptive Offset (SAO) filtering within encoders and decoders, such as according to the High Efficiency Video Coding (HEVC) standard, and similarly configured coding devices. The number of Band Offset (BO) modes and the number of necessary offsets is reduced. The invention beneficially provides simpler coding, reduces temporary buffer size requirements, and can yield a small performance gain over existing SAO techniques of HEVC test model HM 5.
