Title:
METHOD AND APPARATUS FOR PROCESSING VIDEO SIGNALS
Document Type and Number:
WIPO Patent Application WO/2010/114283
Kind Code:
A2
Abstract:
The present invention relates to a method and apparatus for processing video signals, the method comprising: receiving a video signal; decoding a current frame of the video signal in block units to generate a restored frame; and acquiring first and second flags to acquire a filter coefficient which is adaptively determined from the video signal for each slice on the basis of flag information, or performing deblocking filtering with a predetermined filter coefficient. Moreover, the present invention relates to a video signal processing method which includes an inter-frame prediction method that efficiently determines a motion vector to perform motion prediction, as well as a method for performing inter-frame prediction for a residual image. The method for processing video signals according to the present invention can increase the compression encoding efficiency of a video signal by performing accurate motion prediction and residual image prediction, and can improve the quality of a restored image by removing distortion which occurs when restoring an image and performing a filtering operation for restoring an image that is nearly identical to the original image.
