Sony's STR-DA6400ES and STR-DA5400ES receivers do HD streaming over CAT5e



Each week Ross Rubin contributes Switched On, a column about technology, multimedia, and digital entertainment.

The past few years have seen a wide range of wireless technologies proposed to substitute for the now nearly ubiquitous (at least in terms of new HDTVs) HDMI connectors, but the dust is just starting to settle. Some proposals involve squeezing more juice out of 802.11n. Others rely on ultrawideband technology. Yet another that has many in the industry excited is from SiBeam, which intends to use the 60GHz band to deliver uncompressed 1080p video at 4Gbps. That technology, embraced by a group called WirelessHD, had received the most public support among major consumer electronics companies, with Panasonic, Sony, Samsung, Toshiba and LG listed on its site as promoters (and others listed as adopters).
But WirelessHD is still a ways from consumer availability and recently another wireless high-definition technology has attracted some heavy hitters of its own, including Sony, Samsung, Sharp and the cable set-top division of Motorola. Amimon's WHDI (Wireless Home Digital Interface) is different from many of its emerging competitors because it is designed, like WiFi, to be a technology that blankets the home, whereas most competitors focus on an in-room solution. WHDI even operates in the 5GHz band (like 802.11a and 802.11n), but sheds the costly bandwidth overhead WiFi utilizes to correct transmission errors. In contrast, WHDI is a "video modem" technology that attaches to a device's video output to send uncompressed 1080p video. After that, it's survival of the fittest for the bits.

So we waffled on whether to go with a sad Moto or happy Moto face, but as we've stated in the past, we suppose we'll keep on keepin' on with the former until something marvelous happens. Nearly four months to the day after Motorola split in two, along comes word that the separated home and networks division will now be segmented into three distinct units: broadband home solutions, broadband access solutions and cellular networks. According to a statement put out by the firm, the "organizational change will ensure that home and networks mobility remains agile, focused and ideally aligned to realize its growth potential," which is about as canned a statement as you could ever hope for. We've heard that three's company, but who knows how it'll play out here.
That nasty Windows Home Server data corruption bug might finally be a thing of the past, as WHS Power Pack 1 has gone live after a month-long beta test. Not much else to the enhancement suite: x64 support and support for backup to external media are along for the ride, but otherwise it's mostly performance tweaks. Go on and grab it now, you crazy home-server admins.
Every so often, we get wind of some new "breakthrough" from a few guys / gals in a lab that promises to simply revolutionize the web. A team from the University of Sydney is the latest bunch to do so, claiming that a piece of scratched glass (or a Photonic Integrated Circuit, if we're being proper) could enable internet speeds 60 times faster than "current Australian networks." Essentially, the "circuit uses the scratch as a guide or a switching path for information," and the resulting product is "photonic technology that has terabit per second capacity." Call us when you folks get everything ironed out -- we'll be over at Sigbritt Löthberg's house.
