Abstract: Methods of searching for a sync word in an MPEG compressed audio bitstream including a plurality of MPEG audio frames can include determining whether first data in the bitstream has a value equal to a sync word value. It can be determined whether the first data is a valid sync word based on a comparison of a plurality of data that are separated in the bitstream from the first data by at least a frame length to the sync word value.

Abstract: A scrolling unit and a projection system using the same are provided. The scrolling unit is formed by spirally arranging on an outer circumferential surface of a column-like plate at least one lens cell which separates the incident light into a plurality of beams. As the scrolling unit rotates about a predetermined rotating axis, a lens array, defined by an area of the scrolling unit through which light passes, moves rectilinearly. Due to the use of the scrolling unit, a simple projection system can be obtained, and color scrolling is easily performed.

Abstract: A gradation data processing method for shortening printing time by processing a signal per bit column makes a heating element generate heat in the mid portion of one line printing time for a low gradation and makes the heating element repeatedly generate heat in all ranges during high gradation printing. The gradation data processing method includes steps for storing per line an N-bit picture data capable of expressing the 2.sup.N gradation, reading per predetermined bit column the N-bit picture data capable of expressing the 2.sup.N gradation and printing per the predetermined bit column the picture data read during the reading step while allowing the picture data to have respectively different heating time per the predetermined column.

Abstract: A high speed thermal printer including a maximum data detector for detecting maximum gradation data from the image signal of a line received from a signal input source on a line-by-line basis, a drum motor for transporting printing paper, a reel motor for transporting film containing printing dye, and a servo controller for controlling a printing speed by varying the speed of the drum motor and the reel motor in accordance with the detected maximum data value. The printer has the advantages of the drum motor and reel motor being driven at a constant speed for the duration of the maximum gradation printing, and the dye being expressed uniformly throughout the printing line. Thus, high quality printing can be achieved and the printing time decreased by the motors being driven at a constant speed to the following printing position after the maximum gradation of a line has been printed.
