摘要： The currently existing ISO/ A VC file format is modified by providing extensions to store and access video content currently being defined by the SVC standard. Specifically, extensions to the AVC file format are made to provide a new SVC file format that enables the storage (88) and access of scalable video data. The scalable video data is stored as a single track within a media data section of the SVC file format. New extensions are defined for description entries and boxes within a metadata section of the SVC file format. These extensions provide means for extracting sub-streams or layers from the single track of scalable video data (22) stored in the media data section.

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 method and apparatus of using logical mode numbers during both prediction and coding in the bit stream, such as for high efficiency video coders (HEVC). These logical intra mode numbers are sorted based on angle which as a result leads to improved coding designs with fewer and smaller look-up tables, and a small gain in coding efficiency. Furthermore, by using this type of naming, the number of most probable modes (MPMs) can be readily extended since no additional tables are required. The use of three MPMs achieves a larger gain of 0.25% and 0.31% for the AI_HE and AI_LC cases, respectively.
