Samsung has noted today that a two year old LCD patent dispute with Sharp has now been settled, with the Tokyo court upholding Samsung’s countersuit.
In 2007, Sharp sued Samsung over unspecified infringements, and Samsung quickly filed two countersuits as well as asked the US International Trade Commission for a full investigation into the matter.
The WSJ adds that “patent-infringement lawsuits are common in the highly competitive flat-panel display industry,” especially as competition increases and market share becomes more important.

California-based Tzero Technologies has demonstrated its new second generation ZeroWire in Tokyo. The new ZeroWire enables wireless HDMI transmission with Ultra Wideband (UWB) technology, which is able to transfer Full HD (1080p) resolution video at 60 frames per second. The product is at first targeted at Japanese market, but has passed the regulatory tests in Europe and the U.S. as well.
Tzero calls ZeroWire the first commercially viable wireless HDMI solution with an estimated material cost of less than $50. It support HDMI 1.3a and HDCP and therefore is “Hollywood Approved”, according to the press release. With 480 Mbit bandwidth the ZeroWire is able to transmit Full HD resolution video and 7.1 digital surround audio at ranges greater than 20 meters.
Due to its higher bandwidth the rival WirelessHD is a more viable option for future technologies. WirelessHD supports theoretical data rates of up to 20Gbps but is limited by the 10.2 Gbit bandwidth of the wired HDMI 1.3a.

Two researchers plan to provide details at next week’s PacSec 2008 conference in Tokyo on how Wi-Fi Protected Access (WPA) is vulnerable to attack. Of course, this does not mean that WPA is as vulnerable to compromise in the same way that Wired-Equivalent Privacy (WEP) is, far from it in fact. The weakness in WPA is being reported by Martin Beck and Erik Tews, two graduate students in Germany. The attack could make it possible to compromise certain communications in less than 15 minutes.
The researchers found the weakness in the lesser of two WPA security protocol, Temporal Key Integrity Protocol (TKIP). Attackers can use the techniques to decrypt limited communications and can recover a special integrity checksum and send up to seven custom packets to clients on the network, according to SecurityFocus.
“The new attack on WPA is not a complete key recovery attack,” Tews said in an email to SecurityFocus. “It just allows you to decrypt packets and inject packets with custom content. But there is only a single short-term key recovered during the attack.”
