I wonder what the cable manufacturing companies will do when everything goes wireless…
In what may be a competing technology to the 802.11n wi-fi standard that several manufacturers are looking to for wireless HD communication, Tzero Technologies and Analog Devices yesterday announced that they have created a wireless HDMI interface that uses UltraWideBand technology.
Though they see benefit in traditional wi-fi, they say that in a video environment it can be problematic. The standards called for in UWB – which is also the basis for a future wireless USB – state that reliability must be at least 95% with packet error rate of less than 1 in one hundred million, and resistance from interference caused by microwaves and cordless phones.
The company had announced developments in this area in June:
TZero, a startup in the Intel-led WiMedia camp, claims its components will be able to produce 100-Mbit data rates across distances of between 10 and 30 meters, executives said. The company is producing an integrated design – a Media Access Controller (MAC), the physical layer (PHY) as well as the antenna – which will enter production in July, they said.
Here’s some additional coverage of the announcement:
The companies’ first wireless HDMI setup is a standards-based system, predicated on the standards set forth by Panasonic, Philips, Samsung, Sharp, and Sony in July of 2003. Other wireless HDMI technologies introduced to date have been proprietary, both Tzero and Analog Devices alleged.
I just hope the industry rallies behind one standard. We certainly don’t need multiple ultrawideband systems to add to an already confusing product landscape.
