Not that Macnica is the first to offer up a method for transmitting HD / HDMI over coaxial cabling, but it has taken the time in Tokyo to showcase a new system that relies on a Sigma Designs UWB transmission chipset (dubbed Windeo). The display saw high-definition content passed 100 meters over coaxial cable without noticeable degradation, and booth attendees at ESEC 2008 stated that the effective throughput was close to 120Mbps. We're still quite aways from this stuff being commonplace in the home, but with Pulse~LINK and Tzero battling it out in the courtroom over patent issues, we suppose someone has to pick up the slack.
