Wireless HDMI Solution Eliminates Cords, At a Cost
Posted by Suhit Gupta in "THOUGHT" @ 11:00 AM
"Ultrawideband chipmaker TZero has partnered with Analog Devices to announce an HDMI wireless technology that would allow high-definition video and audio to be transmitted between devices at up to 480 Mbps without the use of cords. With the use of a transmitter and receiver, the user would be able to transmit high-definition content from any HDMI-enabled device, such as a DVD player or a game system, to the receiver attached to the HDMI display from up to 30 meters away. No line-of-sight is required, which would allow much more flexibility in placement of devices, the ability to transmit to multiple HDMI sets around the house from one device, and the elimination of the greatly-feared cord gnome. Analog Devices is contributing its JPEG2000 compression to compress the stream, which will then be transmitted via RF from a TZero chip to the HDMI receiver on the other end. At 480 Mbps (60MBps), there's just enough bandwidth to watch uncompressed 720p in an ideal "no packet loss, no interference" wireless networking environment."
It is said that apparently, once traffic conditions are accounted for, 720p video and higher will effectively be compressed, and 1080i will require more than a 50% compression level. Hmm, so would you be willing to trade-off quality for the elimination of wires? I am on the fence about this.
