STMicroelectronics and Arkados join up on HomePlug AV SoC

HomePlug AV has been around for what seems like eons, but regardless of how hard it tries, it never seems to really take hold in the market place. That being said, two big names in the industry are teaming up to give it yet another push, as STMicroelectronics and Arkados join hands to "develop and manufacture a 200Mbit-per-second HomePlug AV wideband powerline modem System-on-Chip (SoC)." If all goes to plan, it'll become the world's first HomePlug AV SoC, and it's being designed to "power applications ranging from simple Ethernet-to-powerline bridges to full-featured products as wide ranging as HDTV distribution, digital set-top boxes, IPTV, whole-house audio, networked digital picture frames, surveillance systems, etc." We'll see if anyone notices when it ships in mid-2009.CoAir: world's first UWB chipset with wireless, coax and gigabit Ethernet

Sigma Designs has been dabbling in wireless HD technologies for eons, so we aren't going to get too excited until we see this here system-on-chip (SoC) actually hit some products that we care about. Still, the CoAir is a fairly sweet concept, wrapping integrated wireless, coax and gigabit Ethernet capabilities into one single chip aimed at whole home networking. Put simply (or as simply as possible), this chip is the world's first to "simultaneously deliver multiple independent streams of video and data over coax cable, Ethernet cable and wirelessly without compromising quality of service and throughput." Based on the WiMedia standard, it can reach speeds of up to 480Mbps with UWB (ultra-wideband) wireless streaming, and room-to-room linkage via UWB-over-coax can peg those same rates. What we have here is a great basis for building a whole home server on, but until said device emerges and performs flawlessly, we'll just smile and carry on.Tzero's WiMedia-based ZeroWire uses UWB for HD streaming

While Tzero has been at the forefront of ultra wideband technology for some time, the firm is upping the stakes even higher with its WiMedia-based TZC7200 ZeroWire chipset. The UWB semiconductor solution was designed to deliver "real-time high-definition video" either wirelessly or over cabling, and can even open new doors for "distributing entertainment content throughout the entire home using existing coax." Reportedly, this device can pipe multiple streams of HD video through your average cable network at the tune of 480Mbps, and it boasts application integration including IP, UDP, TCP/IP, multicast, and unicast. Notably, ZeroWire is "comprised of both a Radio Frequency IC (RFIC) as well as a baseband and media access control system-on-chip," and while the chipset is listed is being available immediately, you'll need to contact Tzero yourself to fetch the pricing details.
