D-Link finally ships the DXN-221 Coax Ethernet adapter

by Nilay Patel posted Apr 20th 2009 at 8:01PM


It's taken almost a year, but D-Link is finally shipping its DXN-221 Coax Ethernet network adapter. The MoCA-certified box does exactly what it says -- it turns your existing coax cabling into a giant Ethernet network without interfering with TV signals, allowing you to get hardwired network speeds anywhere in your house without having to run Cat6. A pair will set you back $239 at retail, but it looks like D-Link is selling them direct for $156.

Is your cable company of the present your IPTV provider of the future?

by Richard Lawler posted Apr 7th 2009 at 11:39PM

It didn't make waves at the Cable Show, but the New York Times reports further off than the CableCARD and streaming solutions of the present, cable's future could be in delivering Internet video directly to your PC or other devices. Delivering IPTV would be far more efficient than current video delivery systems, and could offer higher quality than current Internet streaming services. Of course, the glacial speed of current technology rollouts doesn't engender confidence we'll see any of these advances very soon.

Gennum's Aviia enables 1080p surveillance over coax

by Darren Murph posted Feb 28th 2009 at 12:46AM


These days, it's just not enough to have a grainy, low quality loop of a crook robbing a convenience store. No one understands this better than Gennum, who has just introduced a new audio / video interface for professional and industrial applications (such as advanced video security and surveillance systems) that will enable 1080p transmissions over existing coaxial cables up to 100 meters long. The main selling point is this technology's ability to work over existing coax infrastructures, giving CCTV networks the ability to capture and distribute content at high resolutions without upgrading to CAT5 or the like. Big Brother just found a way to keep a much, much clearer eye on you -- better watch your steps, bub.

Intellon ships 26 million HomePlug-based Powerline ICs -- who's buying?

by Darren Murph posted Feb 11th 2009 at 12:18AM


Intellon, the outfit responsible for providing HomePlug-compatible integrated circuits for all manners of applications, is pretty jovial today. Just this month, it surpassed the 26 million mark in terms of IC shipments, which have apparently gone to manufacturers of home networking, networked entertainment, Ethernet-over-Coax (EoC) and smart grid equipment. While all that may be fine and dandy, we're wondering just how many people outside of Intellon (and its tightest group of friends) actually care. To date, HomePlug is still struggling for recognition outside of the hardcore custom install market, and with wireless technologies gaining traction each day, we're left to wonder if HomePlug even has a shot at a second (or are we at third now?) life. Anywho, don't let us halt the party, but Intellon might want to divert some of that celebration cash to marketing.

Netgear's Coax-Ethernet Adapter up for pre-order

by Darren Murph posted Jan 29th 2009 at 8:53AM


Netgear quietly introduced us to its MCAB1001 MoCA Coax-Ethernet adapter (among other things) at CES this year, but the curiously useful device has just now set itself up for pre-ordering. Put simply, this is the device to get for those who both loathe wireless (and all those inexplicable dropouts) and can't pony up the courage / fundage / willpower to wire their home with Ethernet. By enabling users to extend Ethernet signals over existing in-wall coax cabling, you can easily pass along web content, Blu-ray / DVD material or practically any other digital signal over the coax network that's (hopefully) already established within your domicile's walls. Yeah, $229.99 is a bit pricey, but go price out a house full of Ethernet and then reevaluate.

[Thanks, Matt]

Broadcom produces MoCA-integrated SoC for HD STBs

by Darren Murph posted Jan 12th 2009 at 10:37AM


Ready to sling recorded content around your home via the coaxial wiring in your home? Broadcom is. The outfit has just introduced the industry's first MoCA-integrated SoC solution for use in high-def set-top-boxes and gateway applications, which would theoretically "transform a subscriber's existing coax cable infrastructure into a whole-home media distribution network." If you still can't piece together the potential here, we're talking whole-home digital media distribution over one's existing coax network, and DLNA support is thrown in too. Who knows when your cable company will decide to adopt an STB with this within, but tomorrow would be good.

VUDU certifies MoCA Ethernet-to-coax bridge for HD streaming

by Darren Murph posted Jan 10th 2009 at 10:36AM


Hard to say how much of an impact this will have -- after all, VUDU's already expressed its love for wire-free applications -- but the aforesaid movie set-top-box company has certified MoCA as a wired home networking solution for HD streaming. We get the impression that users looking to pipe VUDU content through their existing in-wall coaxial network can just pickup a MoCA Ethernet-to-Coax bridge, but as always, YMMV.

DLNA gives thumbs-up to MoCA standard for new guidelines

by Darren Murph posted Dec 20th 2008 at 3:30PM


You know that DLNA support that your media streamer has, which currently only supports WiFi and Ethernet as approved LAN standards? Yeah? Well MoCA is about to join in. Yep, the Digital Living Network Alliance (DLNA) has given the green light to the Multimedia over Coax Alliance (MoCA) technology standard for "incorporation into the next version of its Networked Interoperability Guidelines," which should be out in early 2009. The guidelines will aim to "unite various consumer electronics, personal computer and mobile device technologies into a cohesive home networking environment," and being that MoCA is an open initiative intended to distribute multimedia over a home's existing coaxial network, it's a wonder the two haven't linked up earlier. Who says coax is dying?

How do you feel about ZeeVee'x ZvBox?

by Darren Murph posted Oct 17th 2008 at 9:01PM


This week's How Would You Change over on Engadget Classic contains a product that's quite relevant to us: ZeeVee's ZvBox. You already read our take on this little localcaster, and now it's your turn to rant. Head on over and drop your comments along with the rest.

HANA Entertainment Box looks to pass along HD content over coax

by Darren Murph posted Aug 26th 2008 at 3:11AM

Coaxial cabling has long since been viewed as a premiere option for passing along high-def content within the home. After all, in most places it's already neatly installed within the walls. The High-Definition Audio-Video Network Alliance (HANA) has announced its intentions to release a HANA Entertainment Box reference design based on the new (UWB-based) 1394 Over Coax standard; products based on said design will enable consumers to "download HD content from any broadband connection or HD cable set-top-box and watch it in any room in their home with a coax jack and a remote control." HANA is hoping to have the reference design and initial prototypes out the door in Q4, though we wouldn't hold our breath.

Ask Engadget HD: What is switched digital video (SDV)?

by Darren Murph posted Jul 2nd 2008 at 12:00PM Featured Story


With scads of cable providers slowly but surely converting markets and delivering channels via switched digital video, we reckoned now was an excellent time to dust off the terminology dictionary and dig in deeper. Fittingly, Jarad agreed:

"I've seen that lots of markets are being switched over to SDV lately, and I've noticed CableCARD users are generally upset whenever this happens. Why is that? I thought SDV was supposed to free up space so that more high-definition channels could be distributed on the current network?"

If you've suddenly found yourself wondering the same, head on past the break for the low-down.

Federal court ratifies Pulse~LINK UWB patents in Tzero case

by Darren Murph posted Jun 24th 2008 at 4:46PM


At long last, it seems the legal spat between Pulse~LINK and Tzero has come to an end. Federal courts have ratified the former company's patents in a UWB-over-coax patent infringement case against Tzero, affirming that Tzero will now have to pay licensing fees to use Pulse~LINK's technology. In the settlement, it was noted that Tzero had "suspended development of products that were the subject of the legal action," and if it chose to re-introduce any of those wares, it would first cut a check to Pulse~LINK. Time to hug it out? Nah, we thought not.

D-Link introduces DXN-221 Coax Ethernet Adapter Kit

by Darren Murph posted May 28th 2008 at 9:56AM

D-Link's no stranger to HD streaming, and the outfit is proving that it's still got game by announcing the Coax Ethernet Adapter Kit. The Multimedia over Coax Alliance (MoCA)-certified package consists of two DXN-220 adapters, each of which boast coaxial F-type connectors and an Ethernet port meant to give internet / network access to various rooms without worry over wireless connections flaking out on you. As you can tell, this one was designed to expand home networks without requiring any additional wiring (if you're pre-wired for cable, that is), and being that it operates in the 800MHz to 1,500MHz range, there won't be any interference with cable TV transmissions or the like. The DXN-221 kit -- which includes a pair of the aforementioned adapters -- will be available in Q3 for $199.99, while individual adapters can be purchased for $109.99 apiece.

Macnica demonstrates UWB-over-coax HD transmissions

by Darren Murph posted May 17th 2008 at 9:58PM


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.

Ethereal's HDMI/COAX extends 1440p up to 300-feet

by Steven Kim posted Feb 19th 2008 at 1:51PM

Ethereal HDMI/COAX converterHDMI has taken over in the living room, but custom installers still keep component video in their bag of tricks, especially for long runs (HDMI repeaters notwithstanding). There's plenty of bandwidth in coaxial, and longer runs are possible -- witness the Ethereal HDMI/COAX box that converts your HDMI input to signal on 4-conductor coax, and then carries the signal up to 300-feet downstream to an identical box that stuff all the bits back into HDMI. These HDMI-over-coax solutions are just the thing if you've already got coax running through your walls, you don't want to introduce any unnecessary digital-to-analog conversions into your data chain, and you've put your source components far away from their destination. No word on pricing, but you should be able to get your mitts on these in about 4 months.
