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-TH.261, ISO / IEC MPEG-1 Vision, ITU-TH.262 or ISO / IEC MPEG-2 Vision, ITU - TH.263, ISO / IEC MPEG-4 Vision and IT...

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 an RL picture in a first access unit, and the EL having a first EL picture in the first access unit, 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 a splice point where first video information is joined with second video information including the first EL picture, and perform, based on the determination of whether the first EL picture is an intra random access point (IRAP) picture and whether the first access unit immediately follows a splice point, one of (1) refraining from associating the first EL picture with a second set of parameters that is different from the first set of parameters, or (2) associating the first EL picture with a second set of parameters that is different from the first set of parameters. 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, for example, in the standards defined by MPEG-2, MPEG-4, ITU-TH.263, ITU-TH.264 / MPEG-4 Part 10 Advanced Video Coding (AVC), currently Video compression techniques described in the developing High Efficiency Video Coding (HEVC) standard and extensions to such standards.
