Abstract
A method and system for supplying a digital video signal from a source to a sink are described. The digital video signal includes digital video data for three different colors and a pixel clock signal, such as DVI and HDMI. The digital video data and the pixel clock signal are received at a transmitter which sends a signal representative of the frequency of the pixel clock signal over a cable connecting the transmitter and a receiver. Digital video data for three different colors is sent over three different twisted wire pairs of the cable to the receiver. A local pixel clock signal is generated at the receiver using the signal representative of the frequency of the pixel clock signal. The local pixel clock signal is used to process the received digital video data and recovered digital video data and the local pixel clock signal are output.
