Information processing device and information processing method, program storage medium, program, data structure, and manufacturing method for storage medium
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.

a converting step for obtaining font style data of said font style having an outline in the case whereby said font style having an outline is specified in said font style specifying information held by the control processing of said attribute data holding control step and converting said character object held into subtitle data, using at least said font style data, the converting step further comprising:
obtaining both the font style data of said font style having an outline and the width specifying information in the case that said font style having an outline is specified in said font style specifying information, and
performing processing to expand or contract the width of the character object outline corresponding to said font style data obtained with said obtaining, based on said width specifying information,
wherein the 1) font style data, including an indication of whether the font has an outline, and the 2) width specifying information are distinctly stored parameters within a dialog style set having a plurality of parameters,
wherein the dialog style set includes, in addition to the font style data and the width specifying information, player style data indicating whether or not permission is granted to change the dialog style set to a user's individual style,
the font style data indicates a value from defined values of normal, bold, italic, bold and italic, outline bordered, bold and outline bordered, italic and outline bordered, and bold italic and outline bordered, and
wherein the dialog style set including the font style data, the width specifying information, and the player style data is stored in a data structure in an unmodifiable fashion,
wherein the font style data obtained by the converting and used to convert said held character object into subtitle data is unmodified from the font style data stored in the data structure.
3. A non-transitory computer storage device having computer-readable instructions stored thereon that when executed by a computer cause the computer to implement a process for generating subtitle data to display subtitles corresponding to a predetermined AV stream, comprising:
a character object holding control step for controlling the holding of a character object in order to display said subtitles;
an attribute data holding control step for controlling the holding of attribute data which includes at least font style specifying information which can specify at least a font style having an outline as a font style to be applied for said character objects, 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 said font style having an outline is specified in said font style specifying information; and
a converting step for obtaining font style data of said font style having an outline in the case whereby said font style having an outline is specified in said font style specifying information held by the control processing of said attribute data holding control step and converting said character object held into subtitle data, using at least said font style data, the converting step further comprises:
obtaining both the font style data of said font style having an outline and the width specifying information in the case that said font style having an outline is specified in said font style specifying information, and
