VESA Adds HDCP to DisplayPort Specifications


The Video Electronics Standards Association (VESA) today announced proposed changes to the DisplayPort standard. The new DisplayPort 1.1 adds capabilities to support High Bandwidth Digital Content Protection (HDCP).

The DisplayPort Task Group has proposed DisplayPort Version 1.1 for consideration by the VESA membership. Task Group member companies proposing the new version include AMD, Dell, Genesis Microchip, HP, Intel, Lenovo, NVIDIA, and Samsung Electronics.

DisplayPort 1.1 adds capabilities to support High Bandwidth Digital Content Protection (HDCP) in addition to DisplayPort Content Protection (DPCP) and includes technical enhancements that enable PCI-Express design compatibility in DisplayPort devices. These changes improve DisplayPort?s integration capability within graphics processors and chipsets and improve interoperability with earlier digital interfaces.

HDCP version 1.3 for DisplayPort will be provided by the DCP LLC. This version, expected to be final in early 2007, allows products supporting DVI or HDMI and DisplayPort to share a common key set.

DisplayPort is designed to be a long term replacement for DVI, LVDS and eventually VGA in PCs. Compatibility with HDMI and DVI is also possible with DisplayPort products. An Interoperability Guideline providing recommendations for products supporting all three specifications is currently in development.

The VESA DisplayPort Task Group is also working to complete a compliance and interoperability program for DisplayPort connectors, cables and devices to ensure functional compatibility between DisplayPort products.

DisplayPort version 2.0 -- a planned upgrade to the specification that will increase capacity and add new features based on DisplayPort?s micro-packet architecture while maintaining full backward compatibility with DisplayPort 1.1, is on deck for definition by the DisplayPort Task Group during 2007.
