Embodiment Construction

[0021] overview

[0022] The techniques described in this disclosure generally relate to scalable video coding (SVC), scalable video high-efficiency video coding (SHVC), multi-view coding, and 3D video coding. For example, the techniques may be related to and used with or within the High Efficiency Video Coding (HEVC) SVC extension. In the SVC extension, there may be multiple layers of video information. A layer at the bottommost level may serve as a base layer (BL), and a layer at the top may serve as an enhancement layer (EL). In MVC, the term "view" can be used instead of the term "layer". Accordingly, references in the present disclosure to "layer" or "layers" may be replaced with "view" or "views", respectively. An "enhancement layer" is sometimes referred to as an "enhancement layer," and these terms are used interchangeably. Layers in between may act as either or both enhancement layers or base layers. For example, a layer in the middle may be an enhancement laye...

Abstract

In one embodiment, an apparatus configured to code video data includes a processor and a memory unit. The memory unit stores video data associated with a first layer having a first spatial resolution and a second layer having a second spatial resolution. The video data associated with the first layer includes at least a first layer block and first layer prediction mode information associated with the first layer block, and the first layer block includes a plurality of sub-blocks, wherein Each sub-block is associated with corresponding prediction mode data of said first layer of prediction mode information. the processor derives the prediction mode data associated with one of the plurality of sub-blocks based at least on a selection rule, upsamples the derived prediction mode data and the first layer block, and The upsampled prediction mode data is associated with each upsampled sub-block of the upsampled first layer block.

Description

technical field [0001] This disclosure relates generally to video coding and compression. 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 radiotelephones, video teleconferencing devices and similar devices. Digital video devices implement video compression techniques such as those described in: MPEG-2, MPEG-4, ITU-T H.263, ITU-T H.264 / MPEG-4 Part 10 Advanced Video Standards defined by Coding (AVC), High Efficiency Video Coding (HEVC), and extensions of such standards. Video devices may more efficiently transmit, receive, encode, decode, and / or store digital video information by implementing such video coding techniques. [0003] Digital ...
