What is WirelessHD™ Technology?

Living-Room-Photo-sm

WirelessHD technology is a revolutionary new standard that lets you hang your HDTV on the wall with no audio or video cables and still get the best possible all-digital HD picture and audio quality from your home theater components anywhere in the room!

WirelessHD technology uses extremely high-speed radio frequency (RF) technology to deliver an uncompressed, all digital Full HD video and audio signal from your in-room home theatre components to your HDTV. That means you get the full high-definition experience – crystal-clear video, multi-channel surround sound audio, and simplified control over your home theatre components – all with the convenience of no wires!

Although WirelessHD technology is new, it is brought to you by some of the biggest names in home theatre components today – brands you know and trust like LG Electronics, Panasonic, Samsung and Sony. So, ask your dealer or retailer about WirelessHD products, and join the WirelessHD revolution today.

Key WirelessHD Features and Specifications

Video Format Support

All standard DTV video formats and timings up to and including FullHD (1080p, 60Hz refresh). This includes 480p, 720p, and 1080i.

Audio Format Support

  • 2 channels of 192 KHz 2 channel LPCM
  • 5.1 channels of 24-bit 96 KHz multi-channel LPCM audio
  • 13.1 channels of 24-bit 192 KHz compressed Dolby TrueHD(r) or DTS-HD audio (R)

Remote Control Capability

Allows you to use the remote control that comes with your TV to switch between different content sources, such as from your DVR to your Blu-ray player, as well as Play, Pause and Rewind.

Security

WirelessHD employs approved content protection methods to ensure your content is not ‘copied’ from the wireless transmission.


What’s the Difference between WirelessHD and Wi-Fi Technology? Do I need both?

WirelessHD technology is specifically designed to provide a wireless connection for HD video between home theatre components. Wi-Fi, on the other hand, is a general purpose technology for data communication, including internet access. Wi-Fi uses either a 2.4GHz (802.11a/b/g) or 5 GHz (802.11n) RF signal to transmit data resulting in typical bandwidth of 200 – 300 Mbps (megabits/sec), which is only 10% of the 3 Gbps (gigabits/sec) required to transmit FullHD (1080p video format, 60Hz refresh rate) uncompressed video. Wi-Fi must therefore rely on video compression technology to transmit HD video. This can be problematic for HD video if not all devices in the Wi-Fi network share the exact same compression technology or if compression degrades image quality and adds unacceptable latency, as is usually the case. By contrast, WirelessHD uses 60GHz RF technology (which is more than 10X faster than Wi-Fi) to deliver up to 4Gbps of bandwidth.  That’s more than enough bandwidth to transmit uncompressed FullHD video in pristine audio and video quality with absolutely no compression – providing wired-equivalent quality and latency.

Many HDTVs, Blu-ray players and other home theatre devices today come with built-in Wi-Fi, which is typically used by these devices to connect to the Internet through the wireless router in your home. There is interest among consumers to use Wi-Fi to watch Internet video on their HDTVs using Wi-Fi, even though such video is almost never HD quality. WirelessHD, on the other hand, is specifically designed to wirelessly and conveniently connect your home theatre devices, such as a Blu-ray player, set-top box, game console, digital video recorder (DVR), etc. to your HDTV, providing a high-quality uncompressed HD signal.

Different technologies are suitable for different uses. For example, many mobile phones today embed three different wireless technologies; CDMA or 3G for voice, Bluetooth for headset connectivity and Wi-Fi for Internet access. One wireless technology is not capable of handling all 3. WirelessHD is ideal for sharing and transmitting bandwidth hungry HD quality A/V content and large data files, while Wi-Fi is suited for Internet access, which does not require as much bandwidth.
