Abstract:
A video communicating equipment receiving digital image data input and generating analogue image data output to a computer screen, comprising:a data bus for transmitting the digital image data;a complex programming logic device for receiving the digital image data, generating control signals for synchronizing the horizontal and vertical motion of the scan lines, and then outputting the control signals;a line buffer, responsive to the complex programming logic device, for receiving the control signals and the digital image data and then generating and outputting twice the number of raster image data lines under the control of the control signals;a digital-to-analogue converter for receiving the doubled raster image data lines and then converting into analogue image data; anda multiplexer for receiving the analogue image data and a multiplexer control signal, wherein under the controlling action of the control signal, the analogue image data is sent to the computer screen.
