Abstract
A video processing method and apparatus for displaying a signal input in an analog form in a digital TV is disclosed. The present invention eliminates an interference between signals by unifying a flow of analog video signals having different formats, and several signal formats are processed without change through a basic construction of the hardware. Also, the efficiency is increased by utilizing an ADC, a clock and a clamp pulse generation in common for signals based on different formats. Furthermore, a stable interface operation is executed by reconstructing a horizontal synchronization with a constant width in a clock base, and performing a combination and a separation of digital signals on the basis of such construction.
