Abstract
One embodiment of the present invention uses an abbreviated blanking period, in comparison to the standard VESA and CEA-EIA blanking periods, in order to send data, including low bandwidth, non-timing information, over one or more channels of the digital video link. By shortening the blanking period, the amount of time available for sending data in each scan line is increased, enabling the system to send more data over each channel. The inactive video portion of a scan line sent during vertical sync may also be used to send additional digital data. Shortening the blanking periods and/or using the inactive video sections of the horizontal scan lines adds to the overall data capacity of the link and may be used to send other digital data, such as multi-channel audio, video, control, timing, closed captioning or other digital data.
