    摘要: Discloses herein is a method and apparatus for processing video data of a display device in which dithering noise generating when a motion picture is displayed can be minimized. According to the present invention, the method of processing the video data of the display device includes the steps of comparing data of an ith frame (i is a natural number) and data of a (i+1)th frame to determine whether the data of the (i+1)th frame is a motion picture or a still image, and employing a different dithering method depending upon the determination result of the motion picture or the still image.

    摘要: A data modulation method and a data error correction method are provided. The data modulation method includes generating a channel sequence for an input sequence, determining whether or not the channel sequence violates a Run Length Limit (RLL) constraint, and performing, when the channel sequence violates the RLL constraint, bit flip at a position prior to a position at which the RLL constraint is violated among positions of bits included in the channel sequence. The data error correction method includes detecting an error bit of received data using a parity check matrix, determining whether or not the error bit is an error caused by bit flip, and correcting the error bit when the error bit is an error caused by bit flip for applying an RLL constraint.

The method includes preparing a set of dominant error events from the intersymbol interference characteristics of media; and generating a codeword from the data using a non-primitive generator polynomial that produces a unique syndrome set which can completely specify each dominant error event.
