METHOD AND APPARATUS FOR VIDEO ENCODING AND METHOD AND APPARATUS FOR VIDEO DECODING
Document Type and Number:
WIPO Patent Application WO/2011/126309
Kind Code:
A2
Abstract:
Disclosed are a method and an apparatus for video encoding using bidirectional motion compensation in pixel units and a method and an apparatus for video decoding. The method for video encoding according to one embodiment of the present invention is characterized in that the bidirectional motion compensation in block units for a present block is performed, the motion compensation in pixel units for each pixel of the present block is additionally performed by using pixels of first and second and reference pictures which are used for bidirectional motion prediction and compensation, a bidirectional motion prediction value for the present block is generated by using the result of the bidirectional motion compensation in block units and the result of the motion compensation in pixel units.
