Abstract
A video communicating equipment that receives digital image data and a clock signal as input, generating analogue image data internally and then outputting the analogue image data to a computer screen. The video communicating equipment comprises a line buffer, a complex programming logic device and a digital-to-analogue converter. Using only a normal telephone network and an ordinary computer screen, the video communication equipment of this invention enables both voice and video communication functions. Furthermore, the computer screen can be selected to output either computer images or video communication images.
