The present invention includes receiving prediction mode information, interpolating information and a residual of a current block, reconstructing an interpolating pixel using the interpolating information and a neighbor block, and reconstructing the current block using the interpolating pixel, the prediction mode information and the residual, wherein the interpolating information is generated based on a location of the current block. According to an apparatus and method for processing a video signal, high reconstruction rate can be obtained by improving the related art method having limited intra prediction modes available for a current block located on a boundary area of a picture in encoding in a manner of reconstructing and using an interpolating pixel based on interpolating information. | 02-05-2015 |
20150063008 | INPUT DATA ALIGNMENT CIRCUIT AND SEMICONDUCTOR DEVICE INCLUDING THE SAME - An input data alignment circuit includes a data sampler, a frequency divider, a polarity determination block, and a data alignment block. The data sampler provides a data sequence based on data serially input according to a data strobe signal. The frequency divider generates a data alignment signal based on a divided frequency of the data strobe signal. The polarity determination block determines a polarity of the data alignment signal and provides a control signal based on the determined polarity. The data alignment block aligns the data sequence in parallel according to data alignment signal and control signal and generates output data. | 03-05-2015 |
