Abstract
An apparatus for and method of generating graphic data, and information recording medium storing the same. An apparatus for generating graphic data includes: a line information extractor extracting line information of each line from the graphic data, the graphic data including plural graphic layers; a line data extractor receiving alpha information to be alpha blended with the graphic layers and the graphic data, and extracting line data from the graphic data; and a line information and line data combiner combining the extracted line information and line data.
Claims21
An apparatus for generating graphic data, comprising:
- a line information extractor extracting line information of each line of the graphic data, the graphic data including plural graphic layers;
- a line data extractor receiving alpha information to be alpha blended with the graphic layers and the graphic data, and extracting line data from the graphic data;
- and
- a line information and line data combiner combining the extracted line information and line data.
A run-length encoder, comprising:
- a first run-length encoder run-length encoding a combination of alpha information to be alpha blended with graphic data having plural graphic layers and information on a display device in which respective pixel data included in the graphic data are displayed;
- and
- a second run-length encoder run-length encoding color information on the respective pixel data.
A method of generating graphic data, comprising:
- extracting information on each line from graphic data having graphic layers;
- receiving alpha information to be alpha blended with the graphic layers and the graphic data, and extracting each line data from the graphic data;
- and
- combining the extracted line information and line data.
A method of generating graphic data, comprising:
- run-length encoding a combination of alpha information to be alpha blended with graphic data having plural graphic layers and information on a display device in which respective pixel data included in the graphic data are displayed;
- and
- run-length encoding color information on the respective pixel data.
An information recording medium, comprising:
- graphic/control integrated data including graphic data having plural graphic layers, alpha information to be alpha blended with the graphic data, and information on a display device in which respective pixel data included in the graphic data are displayed.
A method of generating graphic/control integrated data, comprising:
- extracting line information from graphic data of the graphic/control integrated data, the graphic data having plural combined graphic layers;
- extracting line data from the graphic data;
- run-length encoding the extracted line data when the extracted line information indicates that run-length encoding is to be performed, the run-length encoding including run-length encoding a combination of alpha information to be blended with the graphic data and display device information regarding a device in which pixel data are to be displayed, and separately run-length encoding color information of the pixel data;
- and
- combining the extracted line information and the encoded line data.
A video display method of a video display apparatus having a plurality of display devices of different formats, comprising:
- reading line information of each line of graphic/control integrated data and storing the read line information in a buffer;
- analyzing the stored line information;
- reading line data and storing the read line data in the buffer, based on the analyzing;
- run-length decoding the line data stored in the buffer and combining the decoded line data with video data to yield combined data, based on the analyzing;
- and
- converting a color space and a scale of the combined data so that a format of the combined data is compatible with at least one of the different formats.
