Embodiment Construction

[0022] Certain embodiments described herein relate to inter-layer prediction for scalable video coding, such as HEVC (High Efficiency Video Coding), in the context of advanced video codecs. More specifically, this disclosure relates to systems and methods for improving the performance of inter-layer prediction in the scalable video coding (SVC) extension of HEVC.

[0023]In the following description, H.264 / AVC techniques are described in relation to certain embodiments; the HEVC standard and related techniques are also discussed. Although certain embodiments are described herein in the context of HEVC and / or H.264 standards, those skilled in the art can appreciate that the systems and methods disclosed herein are applicable to any suitable video coding standard. For example, embodiments disclosed herein may be applicable to one or more of the following standards: ITU-T H.261, ISO / IEC MPEG-1 Vision, ITU-T H.262, or ISO / IEC MPEG- 2 Vision, ITU-T H.263, ISO / IEC MPEG-4 Vision and...

Abstract

An apparatus configured to code video information includes a memory unit and a processor in communication with the memory unit. The memory unit is configured to store video information associated with a reference layer RL and an enhancement layer EL, the RL having a RL picture in a first access unit and the EL having a A first EL picture, wherein the first EL picture is associated with a first set of parameters. The processor is configured to: determine whether the first EL picture is an intra random access point IRAP picture; determine whether the first access unit immediately follows first video information and includes the first EL picture after a splice point at which the second video information of ; and based on said determination of whether said first EL picture is an intra random access point IRAP picture and whether said first access unit immediately follows a splice point one of: (1) avoid associating the first EL picture with a second set of parameters different from the first set of parameters, or (2) associate the first EL picture with a set of parameters different from A second parameter set association of the first parameter set. The processor may encode or decode the video information.

Description

technical field [0001] The present invention relates to the field of video coding and compression, in particular to scalable video coding (SVC), multi-view video coding (MVC) or 3D video coding (3DV). Background technique [0002] Digital video capabilities can be incorporated into a wide variety of devices, including digital television, digital broadcast systems, wireless broadcast systems, personal digital assistants (PDAs), laptop or desktop computers, digital cameras, digital recording devices, digital Media players, video game devices, video game consoles, cellular or satellite radio phones, video teleconferencing devices and the like. Digital video devices implement video compression techniques such as those defined in MPEG-2, MPEG-4, ITU-T H.263, ITU-TH.264 / MPEG-4 Part 10 Advanced Video Coding (AVC), Video compression techniques are described in the High Efficiency Video Coding (HEVC) standard and extensions to such standards currently under development. Video devic...
