Monster Cable has unveiled a transmitter that wirelessly sends HD video signals from a device such as a Blu-ray player to a high definition TV up to 10m away.
The transmitter sends the video signal using ultra-wideband, or UWB, technology from Sigma Designs Inc.
It will also upscale non-HD signals to high-def resolution before displaying on screen. A receiver plugs into a HDMI port on the back of the TV.
To back up the short-range wireless capability, the boxes can also connect via coaxial cable to reach each other in different rooms, up to 110m away.
Noel Lee, president of Monster Cable, which is better known for its expensive video and audio cables, said: “We had opportunities with lots of other systems that just didn’t have the quality of service.
“Sigma is the first partner we found … that has a robust enough technology.”
The Monster Digital Express HD boxes will be available in the US in October for $299.95 each.
UWB is just one of several technologies being utilised for wireless HD connections, an area that has presented problems in maintaining a steady flow of wireless data at very high speeds.
A consortium that includes Sony, Toshiba and Intel is promoting another wireless technology called WirelessHD, with transfer speeds that are even higher than UWB.
