The present invention relates to a system and method for increasing the digital data capacity of a digital video link without increasing the pixel clock rate. The invention uses a shorter blanking period than the standard blanking period, in order to send more data over each channel of the digital video link. By shortening the vertical and horizontal blanking periods, the amount of time in each scan line available for sending data is increased. The inactive video portion of a scan line sent during vertical sync is also used to send auxiliary digital data, which could be additional channels of digital audio or other digital data. Shortening the blanking periods and using the inactive video sections of the scan lines add to the overall data capacity of the link and can be used to send other digital data, such as multi-channel audio, video, control, timing or other digital data |
