Problems solved by technology

[0004] However, in a conventional encoding device, when generating the predicted motion vector PMV, due to reasons such as the timing of pipeline processing, sometimes the motion vectors of other adjacent motion compensation block data may not be generated yet
In this case, the problem is that the predicted motion vector PMV cannot be generated, and the motion compensation block data cannot be encoded

Abstract

A data processing apparatus capable of encoding all motion compensation block data, wherein, when generating for example a motion vector MV of a motion compensation block data A in macro block data MB_X, when the motion vectors MV of the motion compensation block data B1, B2, and B3 at the periphery of that are not generated, a predictive vector generation unit of a motion prediction and compensation circuit generates a predictive motion vector PMV of the motion compensation block data A by using already generated motion vectors MV of motion compensation block data C1, C2, and C3 in the adjacent macro block data MB_Y in place of them.

Description

technical field [0001] The present invention relates to a data processing method for generating motion vectors of moving image data. Background technique [0002] In recent years, the MPEG (Moving Picture Experts Group) system or other systems have appeared for digitally processing image data while utilizing redundancy specific to image information by applying discrete cosine transform or other normal Alternating transformation and motion compensation are used to compress the image data, so as to efficiently transmit and store information. Devices designed based on the above system have been widely used in information dissemination of broadcasting stations and information reception in ordinary households. [0003] As a development of the MPEG system, an H.264 / AVC (Advanced Video Coding) encoding system for achieving a higher compression rate has been proposed. This H.264 / AVC system performs motion prediction and compression based on motion vectors in the same manner as MPEG...
