Embodiment Construction

[0031]Aspects of this disclosure may relate to various techniques associated with cross-layer parallel processing and offset delay parameters in video coding. In some cases, multi-layer extensions to the High Efficiency Video Coding (HEVC) standard (e.g., Multiview Video Coding Extension to HEVC (MV-HEVC) or Scalable Video Coding (SVC) Extension to HEVC (SHVC) )) to perform the described technique together. The techniques may also be used with other extensions to HEVC, other scalable coding standards, other multi-view coding standards (with or without a depth component), and / or other multi-layer video codecs. It should be understood that the techniques of this disclosure are not limited to any particular video coding standard. Additionally, it should be understood that any of the techniques of this disclosure may be applied independently or in combination.

[0032] As described in more detail below, aspects of this disclosure may include improvements with respect to signalin...

Abstract

In an example, a method of coding video data includes coding data of a video parameter set (VPS) of a multi-layer bitstream, including at least one of data that indicates whether any layers of the multi-layer bitstream have an inter-layer prediction restriction or data that indicates whether tile boundaries are aligned between at least two of the layers of the multi-layer bitstream, and coding the multi-layer bitstream in accordance with the data of the VPS.

Description

[0001] This application claims the benefit of US Provisional Application No. 61 / 846,570, filed July 15, 2013, which is hereby incorporated by reference in its entirety. technical field [0002] The present invention relates to video coding. Background technique [0003] Digital video capabilities can be incorporated into a wide range of devices including digital televisions, digital live broadcast systems, wireless broadcast systems, personal digital assistants (PDAs), laptop or desktop computers, tablet computers, e-book reading devices, digital cameras, digital recording devices, digital media players, video game devices, video game consoles, cellular or satellite radiotelephones, so-called "smart phones", video teleconferencing devices, video streaming devices, and similar. Digital video devices implement video coding techniques such as those defined in MPEG-2, MPEG-4, ITU-TH.263, ITU-TH.264 / MPEG-4 Part 10 Advanced Video Coding (AVC), currently under development The vid...
