Abstract

The invention discloses a method and appratus for encoding / decoding using high resolution filter.Disclosed is a video encoding apparatus. The video encoding apparatus includes a prediction unit for generating a prediction block based on interpolating sub-samples of a reference block referenced by a motion vector of a current block. The video encoding apparatus further includes a subtraction unit for generating a residual block based on subtracting the prediction block from the current block and a transform unit for generating a frequency-transformed block based on transforming the residual block. The video encoding apparatus further includes a quantization unit for generating a quantized frequency-transformed block based on quantizing the frequency-transformed block and an encoding unit for encoding the quantized frequency-transformed block into a bitstream.

Description

[0001] This application is an invention with the application number 201180054874.X, the international application number PCT / KR2011 / 007418, the application date is October 6, 2011, and the invention title is "Method and device for encoding / decoding video using high-precision filters" A divisional application of a patent application. technical field [0002] The present disclosure relates, in some embodiments, to a method and apparatus for encoding / decoding video by using high-precision filters. More particularly, the present disclosure relates to a video encoding / decoding method and apparatus in which a prediction signal is generated using a high-precision filter and a high-accuracy video signal is generated using the prediction signal.
