HDCP technology evolves for wireless

High-bandwidth Digital Content Protection (HDCP), a technology that protects premium entertainment content between a digital set-top box, digital video recorder or Blu-ray disc player and a digital TV, is evolving to support a broader range of digital and wireless interfaces.

One of the first new wireless interfaces addressed by the HDCP revision 2.0 specifications is WirelessHD, a standards-based 60 GHz technology that will enable HDTVs, PCs and portable devices to display, share and instantaneously transmit large multi-gigabyte media files among a variety of devices. Digital Content Protection LLC (DCP), the organisation that licenses HDCP, recently published the HDCP revision 2.0 document entitled, "Mapping HDCP to WirelessHD." Additional HDCP revision 2.0 specifications for specific implementations will follow in the months ahead.

"The combination of ubiquitous HDCP with Wireless HD technology will enable compatibility of new WirelessHD-enabled consumer electronics products with billions of HDMI/HDCP-enabled interfaces already present in consumer homes," said John Marshall, President and Chairman of the WirelessHD Consortium. "HDCP support is a key enabler in accelerating the adoption of WirelessHD technology and essential to fulfilling its promise as an unmatched wireless home entertainment experience."
