Embodiment Construction

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0033] In the prior art, the current CU may include at least two PUs, and the DV prediction values ​​of the at least two PUs are obtained serially, that is, the DV prediction value of the next PU is obtained only after the DV prediction value of the current PU is obtained.

[0034] Specific can include:

[0035] Such as Figure 2a to Figure 2g As shown, a CU (implementation box in the figure) can be further divided into multiple PUs. In HEVC (High Efficiency Video...

Abstract

The invention provides a method and a device for obtaining disparity vector (DV) predictors of prediction units (PUs), relates to the field of video coding, and achieves the effect of obtaining the DV predictors of at least two PUs in the same one coding unit (CU) by serial mode, to improve the parallel processing capability. Specifically, the method comprises the following steps: obtaining adjacent units on the current prediction unit air space; according to the division mode of the current CU, the positions of the current PUs in the current CU and the positions of the adjacent units, determining whether the adjacent units are located in the current CU; and obtaining DV predictors from the adjacent units which are not in the current CU in a preset order and stopping until a DV predictor is obtained. The method and the device can be applied to obtain disparity vector (DV) predictors.

Description

technical field [0001] The present invention relates to the field of video coding, in particular to a method and a device for obtaining a prediction value of a disparity vector of a prediction block. Background technique [0002] JCT3V (Joint Collaborative Team on 3D Video Coding, 3DV video coding joint working group) supports multi-views (multi-view, that is, 2 or more) coding. Multi-view refers to a video sequence that captures the same scene from different perspectives, and there is a strong correlation between each view. Utilize the correlation between each view (view), remove inter-view redundancy through inter-view prediction (inter-view prediction) technology, and improve coding and compression performance. [0003] Inter-view prediction techniques can include: [0004] Use the MV (Motion Vector, motion vector) of the reference view as a reference to predictively encode the current view, that is, the inter-view MV prediction inter-view MV prediction technology.
