PURPOSE: A digital converter for a multi-channel video signal capable of simultaneously inputting a multi-channel signal and changing a channel without stopping a video transmission is provided. CONSTITUTION: In a digital-converter for a multi-channel video signal, a plurality of analog/digital converters(31,32,33,34) each for converting a video signal of a corresponding channel into a digital signal. A plurality of FIFOs(35,36,37,38) store the output signals of the plurality of analog/digital converters(31,32,33,34). A CPU(39) initializes the plurality of analog/digital converters(31,32,33,34) and FIFOs(35,36,37,38), and requests a transmission of video signal inputted to the plurality of FIFOs(35,36,37,38) in synchronism with a sync signal of one camera among a plurality of channel cameras to a DRAM. |
