Abstract: A system and method are disclosed, which controls congestion to efficiently transmit data through a network of grid node network in a grid computing environment where a large amount of data is processed.

Abstract: Disclosed relates to a method and an apparatus for converting gradation data for a color STN-LCD, capable of providing color moving pictures of excellent quality. The apparatus includes a storage buffer 31 for storing input data for driving the LCD, and a frame memory 32 for storing gradation data for driving the LCD panel. A data conversion unit 33 converts gradation data stored in the storage buffer 140 based on the gradation data stored in the frame memory, i.e., previous gradation data that was used for driving the LCD. The data conversion unit 33 subtracts the gradation data stored in the frame memory 32 from the input data stored in the storage buffer 31, multiplies the subtracted result by a predetermined factor to generate a correction value, and adds the correction value to the previous gradation data to generate new gradation data. The generated gradation data is stored in the frame memory 32 as new gradation data.
