Patent ID: 7728851

Claim:
A reproducing apparatus comprising: a graphics processing unit configured to output graphics data containing sub-video data of an RGB color space and further configured to output alpha data indicative of a degree of transparency of each pixel of the graphics data; a conversion unit configured to convert a color space of the graphics data with the alpha data from the RGB color space to the YUV color space, wherein the graphics data that is converted to the YUV color space comprises data of a first format in which the resolution of a luminance signal is equal to the resolution of a chrominance signal; a video decoder configured to output main video data of a YUV color space, wherein the main video data comprises data of a second format in which the resolution of a chrominance signal is lower than the resolution of a luminance signal; an up-sampling process unit configured to execute an up-sampling process for converting the main video data of the YUV color space, which is output from the video decoder, to data of the first format: a blending process unit configured to execute a blending process in which the graphics data that is converted to the YUV color space and the main video data of the YUV color space that is up-sampled to the first format are blended pixel by pixel on the YUV color space, wherein the blending process unit comprises a first down-sampling process unit configured to execute a down-sampling process for converting blended video data to the second format; and a picture data output unit configured to output picture data, which is obtained by the blending process, to a display apparatus.
