The apparatus for printing an image on a printing medium on which a barcode is written includes a sensor unit sensing the barcode and generating a sensing signal. A first counting unit counts the sensing signal to generate a first count value when the value of the sensing signal is changed from a high value to a low value. A second counting unit counts the sensing signal of the barcode simultaneously with the first counting unit to generate a second count value which is initialized whenever the value of the sensing signal is changed. A detecting unit detects the edge of the printing medium based on the first and second count values of the first counting unit and the second counting unit. A reading unit reads the barcode based on the second count value of the second counting unit.

Abstract: A video decoding system is provided. When a DDR SDRAM is used as an external memory, MBs are rearranged and then stored to minimize memory access operations for the MBs at the DDR SDRAM and unnecessary additional word read operations caused by a DDR characteristic. Accordingly, the video decoding system can efficiently perform a memory access operation on MBs for video display and frame decoding by the video decoder. Specifically, the decoding system can reduce the total video decoding time, thereby allowing a surplus memory use time for additional functions of a digital broadcasting receiver.
