Wireless chipset is approved for retransmission

As a DCP approved retransmission technology, Pulse-Link's CWave can now be used in a new class of wireless HD entertainment equipment.

Pulse-Link's CWave UWB wireless-for-HDMI platform has been certified as an approved retransmission technology (ART) by Digital Content Protection, the administrator of the HDCP specification.

This, along with the FCC Certification CWave received in December 2007, represents the primary certification requirements for the commercial release of its CWave wireless-for-HDMI products.

The first products will be available this autumn.

"Pulse-Link's CWave technology was built from the ground up to network premium multimedia content throughout the home", states John Santhoff, Chief Technology Officer of Pulse-Link.

"From the very beginning, we placed a high priority on preserving the content protection mechanisms demanded by content providers".

"This stamp of approval from DCP is important in enabling us to work with partners, such as Westinghouse, to deliver products that allow consumers to experience high-quality HD content wirelessly in their home".

Westinghouse, one of the leading LCD manufacturers in the USA, will begin shipping its new 42 and 47in wireless HDMI HDTVs in the commercial market this autumn.

The fully integrated wireless displays feature Pulse-Link's CWave UWB chipset.

John Araki, Vice President and General Manager, Commercial Business Unit, at Westinghouse Digital Electronics, states: "Pulse-Link's ART certification allows us to ship this first-of-its-kind display for wireless HD entertainment with assurances that it satisfies content providers with the required level of content protection that they demand in today's digital media age".

To receive ART compliance, the technology solution must first be HDCP licensed.

High-bandwidth digital content protection (HDCP) technologies protect high-value digital motion pictures, television programs and audio against unauthorised interception and copying between a digital set top box or digital video recorder and a digital TV or PC.

HDCP is a specification that protects digital entertainment across the DVI/HDMI interface and provides a robust, cost-effective method for transmitting and receiving digital entertainment content to compliant displays.

"DCP is committed to protecting premium commercial entertainment content".

"HDCP content protection enables consumers to enjoy HD content while providing a protected environment for content providers", states Stephen Balogh, President of DCP.

"Pulse-Link's CWave technology meets our requirements for transmitting HD content wirelessly and over coax".

The ART criteria document outlines the DCP and content owners approved method for retransmitting HDCP-protected content between devices, such as in wireless or over coax transmitter/receiver repeaters.

Approved retransmission technologies are found in Appendix C of the HDCP licence agreement, and only those technologies listed in Appendix C are permitted to retransmit HDCP-protected content.

Pulse-Link is a pioneer and innovator in the commercialisation of UWB communications and the first semiconductor company to deliver a wired and wireless solution with Gigabit datarates for true room-to-room networking of interactive high-definition content.

Devices enabled with the Pulse-Link CWave UWB chipset allow HD video content, multichannel audio and high-speed data located anywhere in the home to be shared across the existing coax backbone, in addition to wireless connectivity within each room.
