  • Patent number: 10075668
    Abstract: Described herein is an information processing device, information processing method, program storage medium, program, data structure, and manufacturing method for storage medium wherein a user can determine subtitles with certainty. That is, an attribute buffer holds at least font style specifying information which specifies a font style to be applied for a character object for a subtitle held in a character object buffer, and width specifying information which can specify the width of the outline of the character object corresponding to the font style having an outline. In the case that the font style having an outline is specified in the font style specifying information, a font rasterizer obtains font style data of the font style having an outline, updates the font style data based on the width specifying information, and converts the character object into subtitle data, using at least the updated font style data.

  • Patent number: 10026437
    Abstract: To determine whether or not a correct continuous reproduction disk has been attached, and perform control in accordance with a determination result in a data reproduction process including a first information recording medium and a second information recording medium. A first root certificate transform value is calculated by applying a first transform function to data constituting a first root certificate recorded in the first information recording medium and a second root certificate transform value is calculated by applying a second transform function to data constituting a second root certificate recorded in the second information recording medium. Transform values based on first and second root certificates are compared. A process under execution is continued when the first and second root certificate transform values match. However, the process under execution is stooped or a warning is output when the first and second root certificate transform values do not match.

  • Publication number: 20180197509
    Abstract: There is provided a configuration in which completion of a drawing process by a drawing command executed by an application is detected and a conversion process and a display process are performed on an image to which the drawing process is completed. An application execution unit executing the drawing process and storing a drawing result in a storage unit, a display image generation unit converting a drawn image in the storage unit, and a buffer management unit switching a plurality of buffers in the storage unit are included. The application execution unit calls a drawing completion notification application programming interface (API) after drawing is completed. The buffer management unit switches the buffers in response to the API call. The display image generation unit executes the image conversion on the stored image in the buffer which is not the buffer in which drawing is being executed by the application execution unit.
