Abstract: According to one embodiment, there is provided an information reproduction method that includes executing graphics processing including blend processing of superimposing respective planes of at least video data, picture data and graphics data, and performing control to assure that data in a region except a specific region surrounding a part superimposed on the video data or the picture data in the graphics data is not used for the blend processing but data in the specific region is used for the blend processing when the video data and the picture data vary with time and the graphics data does not vary with time.

Abstract: According to one embodiment, there is provided an information processing apparatus that includes a frame buffer to store graphics data, a control section to perform control to alternately store in a plurality of buffers data of even-numbered lines and data of odd-numbered lines in picture data based on a progressive mode and to perform control to stop and restart supply of data, thereby generating pulled-down picture data, and a field assembling processing section to execute field assembling processing of graphics data having a resolution appropriate for an image size of the frame buffer based on the picture data generated by the control section.

Abstract: A playback apparatus includes an output unit configured to output main video data used as a main image, sub-video data used as a subsidiary image, cursor data to display a cursor, graphics data to display operation guidance, and sub-picture data to display subtitles, a first blend processing unit configured to superimpose the sub-video data, the sub-picture data, the cursor data and the graphics data, and a second blend processing unit configured to superimpose the superimposed data obtained by the first blend processing unit and the main video data.

Abstract: According to one embodiment, a playback apparatus includes first to third digital signal processors. The first digital signal processor includes decode functions corresponding to a plurality of kinds of compression-decoding schemes and decodes first audio data, which is compression-encoded by using an arbitrary one of the plurality of kinds of compression-encoding schemes, thereby generating a first digital audio signal. The second digital signal processor includes decode functions corresponding to the plurality of kinds of compression-decoding schemes and decodes second audio data, which is compression-encoded by using an arbitrary one of the plurality of kinds of compression-encoding schemes, thereby generating a second digital audio signal. The third digital signal processor executes a mixing process of mixing the first digital audio signal and the second digital audio signal, thereby generating a digital audio output signal.

Abstract: A reproducing apparatus includes a graphics processing unit that outputs graphics data of an RGB color space, a video decoder that outputs video data of a YUV color space, a conversion unit that converts a color space of the graphics data from the RGB color space to the YUV color space, a blending process unit that executes a blending process in which the graphics data that is converted to the YUV color space and the video data of the YUV color space are blended on the YUV color space, and a picture data output unit that outputs picture data, which is obtained by the blending process, to a display apparatus.

Abstract: A reproducing apparatus includes an execution unit that executes a separation process by a program on a motion video stream including first video data, and graphics data that includes second video data, and executes a decoding process by a program on the second video data that is obtained through the separation process, a decoder that decodes the first video data, which is obtained through the separation process, and a blending process unit that blends the first video data, which is decoded by the decoder, and the graphics data including the second video data, which is decoded by the decoding process in the execution unit.

Abstract: A reproducing apparatus includes a graphics processing unit that outputs graphics data, which forms a first screen image, in sync with a vertical sync signal and a pixel clock signal, a video decoder that outputs video data, which forms a second screen image, in sync with the vertical sync signal and the pixel clock signal, a blending process unit that executes a blending process for blending the graphics data, which is output from the graphics processing unit, and the video data, which is output from the video decoder, and a picture data output unit that outputs picture data, which is obtained by the blending process, to a display apparatus.

Abstract: A reproducing apparatus includes a graphics data output unit that outputs, on a pixel-by-pixel basis, alpha-data-added graphics data containing graphics data that forms a first screen picture and alpha data that indicates a degree of transparency of each of pixels of the graphics data, a video data output unit that outputs video data that forms a second screen picture, a blending process unit that is connected to the graphics data output unit and the video data output unit, and executes a blending process for blending the graphics data and the video data on the basis of the alpha data that is output from the graphics data output unit, and a picture data output unit that outputs to a display device picture data that forms a screen picture, which is obtained by the blending process.

Abstract: An information processing apparatus includes a first processor, a second processor, an application program, under control of the first processor, issuing a processing execution request to the second processor, an actual processing section, under control of the second processor, executing an application interface processing code defined by the second processor, and an interface that, when an execution request of the application interface processing is issued by the application program, sends the processing execution request to the actual processing section through a communication bus.
