DVI Interface

The PAL, NTSC and SECAM television standards are all several decades old. Even in this digital era, most people still have television sets that use complex analogue signals complying with these standards.
Nevertheless, the end is nigh for these standards. The DVI standard is on its way to becoming the new standard for transmitting video information. The most important property of this interface is that the information is transferred in digital form (24-bit words) instead of in the form of analogue signals.
This circuit shows how the required signals are divided into three data streams in a single-link interface, along with a clock signal.
