Embodiment Construction

[0018] In one embodiment, the present invention provides a method for video encoding, which includes: (a) determining whether a predetermined block of a predetermined size forming a video satisfies a requirement corresponding to a first mode of a plurality of video encoding modes; a predetermined condition; and (b) selecting the first mode as an encoding mode for the predetermined block if the predetermined condition is satisfied.

[0019] In another embodiment, the present invention provides a method for video coding comprising: (a) calculating the ratio of a predetermined block of a predetermined size forming a video to a reference block of a reference picture in inter mode temporal similarity; and (b) determining whether to ignore the encoding process in intra mode based on the calculated temporal similarity, and the spatial similarity between the block of the current picture and neighboring blocks.

[0020] In other embodiments, the invention provides an apparatus for vide...

Abstract

Provided are a method and apparatus for video encoding, in which an encoding mode is rapidly decided and video encoding is performed in the decided encoding mode. The method for video encoding includes determining whether a predetermined block of a predetermined size forming a video satisfies predetermined conditions corresponding to a first mode that is included in a plurality of encoding modes used to encode the video and choosing the first mode as an encoding mode of the predetermined block if the predetermined conditions are satisfied.

Description

technical field [0001] Methods and apparatus consistent with the present invention relate to video encoding, and more particularly, to video encoding in which an encoding mode is quickly decided in video encoding, and video encoding is performed in the decided encoding mode. Background technique [0002] For video encoding according to the H.264 standard concerning video compression, one picture is divided into macroblocks. After encoding each macroblock in all coding modes for inter prediction and all coding modes for intra prediction, the bit rate required for macroblock-based coding, and the degree of distortion between the original macroblock and the encoded macroblock to determine the encoding mode, and perform video encoding in the determined encoding mode. [0003] Inter mode is used in inter prediction, which is aimed at coding the difference between the motion vector information and the pixel values ​​for the purpose of coding the macroblock of the current picture,...
