Embodiment Construction

[0024] Embodiments of the present invention, examples of which are illustrated in the accompanying drawings, will now be described in detail, wherein like reference numerals refer to like elements throughout. The embodiments are described below in order to explain the present invention by referring to the figures.

[0025] FIG. 2 is a block diagram of a decoding device according to an embodiment of the present invention. Referring to FIG. 2 , the decoding apparatus includes an entropy decoding unit 210 , a memory 220 , a memory information processing unit 230 , a motion compensation unit 240 , an intra prediction unit 250 , and a filtering unit 260 .

[0026] The entropy decoding unit 210 entropy-decodes the entropy-encoded block. Entropy decoding is a compression method based on redundancy in the blocks forming an image.

[0027] The memory 220 stores information required to predict motion vectors and derive boundary strength (BS) coefficients. The information stored in th...

Abstract

Provided is a moving picture decoding method and apparatus. The decoding method includes storing coding information on a certain block and neighboring blocks, deriving a filtering coefficient to filter a boundary between blocks and predicting a motion vector of a certain block, based on the stored information, and filtering the boundary between the certain block and the neighboring blocks based on the derived filtering coefficient. Accordingly, the number of the memories and the amount of routing resources needed are reduced.

Description

[0001] This application claims priority from Korean Patent Application No. 10-2004-0059740 filed with the Korean Intellectual Property Office on Jul. 29, 2004, which is hereby incorporated by reference in its entirety. technical field [0002] Embodiments of the present invention relate to a method and device for decoding moving pictures, and more particularly, to a method and device for decoding moving pictures with post-filtering applied. Background technique [0003] H.264 is a new video compression standard that provides stronger compression ratios than legacy standards. H.264 is also called MPEG-4AVC (Advanced Video Coding). According to the H.264 standard, digital TVs, PDAs, web pads, mobile phones, etc. can decode the H.264 standard to play moving images. [0004] A decoder decoding according to the H.264 standard includes a motion vector prediction unit and a filtering unit. The motion vector prediction unit predicts ...
