Embodiment Construction

[0024] 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.

[0025] In the prior art, a CU may include at least two PUs, and the motion vector lists of the at least two PUs are established in a serial manner, that is, the next PU starts to establish the motion vector list after the current PU completes the motion vector list creation.

[0026] Specific can include:

[0027] 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, a CU can have seven...

Abstract

The invention provides a method and device for setting up a motion vector list for motion vector prediction, and relates to the field of video coding. The problem of how to set up the motion vector lists of at least two PUs in the same coding unit in a serial mode is solved, and the parallel processing capacity is improved. The method can specifically comprise the steps that adjacent blocks in the space domain of a current predication block are acquired, and the current predication block is located in the current coding unit; the proper adjacent block of the current predication block is determined according to the division mode of the current coding unit, and the proper adjacent block is located outside the current coding unit; a motion vector predication value is acquired from the proper adjacent block according to the motion vector predication value of the proper adjacent block and the preset sequence, and the acquired motion vector predication value is added into the motion vector list. The method and device can be used for setting up the motion vector list.

Description

technical field [0001] The invention relates to the field of video coding, in particular to a method and a device for establishing a motion vector list for motion vector prediction. Background technique [0002] The inter-frame prediction technology in HEVC (High Efficiency Video Coding, high-efficiency video coding standard) adopts the traditional MCP (Motion Compensated Prediction, motion compensation prediction) method. In terms of motion vector prediction, HEVC adopts the method of multi-motion vector competition. Improves the accuracy of motion vector prediction, thereby improving encoding and compression performance. [0003] HEVC inter-frame prediction modes may include, but are not limited to: Merge mode (merge mode), Skip mode (skip mode), etc., all of which use the method of multi-motion vector competition for inter-frame prediction. When performing motion vector prediction, a motion vector list is used. For Merge mode and Skip mode, a maximum of 4 spatial motion...
