  • Transmission protocols.

About WirelessHD®

Broadcom Corporation, Intel Corporation, LG Electronics Inc., Panasonic Corporation, NEC Corporation, SAMSUNG ELECTRONICS CO., LTD, SiBEAM, Inc., Sony Corporation and Toshiba Corporation, have joined together to form the WirelessHD Consortium, an industry-led effort to define a specification for the next generation wireless digital network interface specification for consumer electronics products. Specifically, the WirelessHD has a stated goal of enabling wire.

  • High interoperability supported by major CE device manufacturers;
  • Uncompressed HD video, audio and data transmission, scalable to future high-definition A/V formats;
  • High-speed wireless, multi-gigabit technology in the unlicensed 60 GHz band;
  • Smart antenna technology to overcome line-of-sight constraints of 60 GHz;
  • Secure communications with DTCP over WirelessHD technology;
  • Device control for simple operation of consumer electronics products;
  • Error protection, framing and timing control techniques for a quality consumer experience.

Why WirelessHD?

The WirelessHD wireless digital interface will serve as the first and only global specification to combine uncompressed high-definition video, multi-channel audio, intelligent format and control data, and Hollywood approved standard content protection techniques. For end-users, elimination of cables for audio and video dramatically simplifies home theater system installation and eliminates the traditional need to locate source devices in the proximity of the display. Also, the technology will support the development of adapter solutions that will be capable of supporting legacy systems.

The WirelessHD specification has been architected and optimized for wireless display connectivity, achieving in its first generation implementation high-speed rates up to 4 Gbps at ten meters for the consumer electronics, personal computing and portable device products. Its core technology, based on the 60 GHz millimeter wave frequency band, promotes theoretical data rates as high as 25 Gbps, permitting it to scale to higher resolutions, color depth, and range.

Finally, with WirelessHD technology, consumers can easily create a wireless video area network (WVAN) by just ‘flipping a switch,’ and turning on their device. The intelligent device control system automatically discovers each device in the WirelessHD network and may be controlled by a standard remote control.

A ubiquitous WirelessHD specification would do much to improve interoperability among devices, and would also expand the capabilities of personal video players, PDAs, and other handheld devices (iPhone/iPod).
