FAQ

What is the new WHDI standard?

The WHDI standard is a new standard for multi-room audio, video and control connectivity. The WHDI standard will define the method by which HD source devices such as BD, DVD player, STBs and PC can deliver wirelessly uncompressed video content to HD display devices, such as LCD TVs, within the home.

Why was WHDI Special Interest Group (SIG) formed?

As several products that implement wireless video have been introduced to the market, the WHDI SIG was formed to enable widespread adoption and interoperability of wireless sources and displays, manufactured by multiple vendors, and utilizing the WHDI technology.

What is the WHDI Technology?

WHDI technology is the wireless transmission technology developed by AMIMON for wireless delivery of uncompressed HD video. WHDI technology utilizes a unique wireless video-modem approach that maintains superb video quality. In noisy wireless conditions where other wireless technologies would severely degrade, WHDI technology maintains a robust link with virtually no loss of visual quality.

What is the relation between WHDI Technology and the WHDI Standard?

WHDI standard is based on WHDI technology and the required protocols and software layers to ensure interoperability and a smooth operation of CE devices manufactured by different vendors.

What is the WHDI SIG announcing?

The WHDI SIG is announcing its formation and its intention to develop a comprehensive new industry standard for multi-room audio, video and control connectivity.

What is the merit of using the WHDI standard?

WHDI standard is the only comprehensive industry standard to enable multi-room wireless uncompressed HD connectivity and control. WHDI standard will enable a wireless interface that will facilitate installation of displays by eliminating the need to run A/V wires. It will allow greater flexibility in the placement of CE devices in the home, and will allow consumers to enjoy their content from multiple sources throughout the home from each TV in the home.

What is the goal of the WHDI standard?

The standard's main goal is to enable wireless uncompressed connectivity from every HD source to every HD display.

What are WHDI SIG's objectives?

WHDI SIG objectives are to complete the specifications including test specification that will enable multiple interoperable WHDI products offered to consumers already in 2009 with high growth after that

How can consumers benefit from WHDI?

Here are a few examples:

• Allowing consumers to hang their super thin HDTV panel on the wall without the need to run A/V wires to the panel
• Connecting the PC in the home office to the TV in the living room and enjoying content such as video files and games on the TV
• Playing a game on the living room TV when the gaming console is actually located in the bedroom
• Connecting laptops and mobile devices such as camcorders and digital cameras to the TV

What applications will be supported?

WHDI will support wireless connectivity of HD video for many CE devices with video capabilities such as LCD and plasma HDTVs, projectors, A/V receivers, DVD & BD players, set-top boxes (STBs), game consoles and PCs.

When will the WHDI standard be ready?

Specifications are targeted for completion by the end of this year. The first WHDI standard based products are targeted to be available to consumers in 2009.

What is the relation between WHDI and Wireless HD?

Both standards support wireless delivery of uncompressed HD Video, however these are two very different standards utilizing different spectrum bands and communication methods which enable different features and capabilities. Unlike WirelessHD which operates at the 60GHz band, WHDI operates on the 5GHz unlicensed band which propagates easily through walls and other obstacles, enabling robust multi-room wireless delivery of HD video.

What is the relation between WHDI and DLNA?

WHDI and DLNA are complementary technologies. While DLNA enables delivery of compressed video streams in the home, WHDI enables delivery of uncompressed HDTV, thereby supporting all HD video sources that do not provide compressed video outputs, such as gaming consoles, PC graphics, BD players, DVD players and set-top-boxes.

What is the relation between WHDI and 802.11n?

802.11n is a specification for general purpose wireless data delivery. WHDI is specific to wireless delivery of video, audio and control. 802.11n can be used for streaming of HD video, however due to rate limitations it can only deliver compressed video. WHDI enables delivery of uncompressed HDTV, thereby supporting all HD video sources that do not provide compressed video outputs, such as gaming consoles, PC graphics, BD players, DVD players and set-top-boxes.

What video rates does WHDI support?

WHDI supports the most common HD video formats including 1080p 60Hz.

What is the range of WHDI?

WHDI operates in the 5GHz unlicensed band, and has similar range as other technologies operating in that band such as 802.11n and 802.11a.

Will WHDI co-exist with 802.11a and 802.11n?

Yes. WHDI will employ spectrum management capabilities to avoid mutual interferences with other transmissions in the 5GHz unlicensed band.

Can other companies join the WHDI SIG?

Other companies will be able to join at a later stage as adopters of WHDI.

Can other companies join the SIG to work on the development of the specifications?

This is a possibility, although no decision has yet been made.

When will WHDI accept adopters?

WHDI will be accepting adopters towards the end of 2008.

What is the cost of becoming an adopter?

The cost has not been determined yet, however it will be similar to the cost of other industry standards.

What is the relation between the SIG members and adopters?

Promoter and adopter privileges will be similar to other similar standardization frameworks such as HDMI. The WHDI Adopter agreement will set the terms for getting access to specification documents, the use of the WHDI logo and the license to necessary claims.

There were previous press releases about products utilizing WHDI technology. What is the relation to the WHDI standard?

WHDI technology is the wireless transmission technology developed by AMIMON for wireless delivery of uncompressed HD video, utilizing a AMIMON’s wireless video-modem approach. WHDI standard is based on WHDI technology and the required protocols and software layers to ensure interoperability and a smooth operation of CE devices manufactured by different vendors.

What is the copy protection used in WHDI?

WHDI will employ an industry approved copy protection protocol that will ensure the highest level of security.
