A digital video recorder , sometimes referred to by the merchandising term personal video recorder , is a consumer electronics device or application software that records video in a digital format to a disk drive, USB flash drive, SD memory card, SSD or other local or networked mass storage device. The term includes set-top boxes with direct to disk recording facility, portable media players with recording, recorders as camcorders that record onto Secure Digital memory cards and software for personal computers which enables video capture and playback to and from a hard disk drive. A television set with built-in digital video-recording facilities was introduced by LG in 2007, followed by other manufacturers. Wikipedia.

Rheumatoid arthritis (RA) is characterized by hyperplastic synovial pannus tissue, which mediates destruction of cartilage and bone. Fibroblast-like synoviocytes (FLS) are a key component of this invasive synovium and have a major role in the initiation and perpetuation of destructive joint inflammation. The pathogenic potential of FLS in RA stems from their ability to express immunomodulating cytokines and mediators as well as a wide array of adhesion molecule and matrix-modelling enzymes. FLS can be viewed as 'passive responders' to the immunoreactive process in RA, their activated phenotype reflecting the proinflammatory milieu. However, FLS from patients with RA also display unique aggressive features that are autonomous and vertically transmitted, and these cells can behave as primary promoters of inflammation. The molecular bases of this 'imprinted aggressor' phenotype are being clarified through genetic and epigenetic studies. The dual behaviour of FLS in RA suggests that FLS-directed therapies could become a complementary approach to immune-directed therapies in this disease. Pathophysiological characteristics of FLS in RA, as well as progress in targeting these cells, are reviewed in this manuscript. © 2013 Macmillan Publishers Limited. All rights reserved.

A millimeter-wave rotary-wave oscillator (RWO) is presented that hybridizes standing- and traveling-wave behavior. This paper presents an analysis of the phase noise of this RWO. The multiphase voltage-controlled RWO is implemented in a 0.12-μm SiGe BiCMOS process using only nMOS devices for the oscillator core. The measured frequency of operation is 45 GHz with 6.5% tuning range and has a phase noise of -91 dBc/Hz at 1 MHz and -112 dBc/Hz at 10 MHz. The power consumption of the oscillator core is 13.8 mW from a supply voltage of 1.2 V. © 2011 IEEE.

A video clip is captured from a television broadcast on each of a plurality of channels. The captured video clips are provided to a display interface, which successively displays the captured video clips within a focus area of a user interface in response to an initiating action by a user. The display interface then discontinues the successive display of video clips to show a particular video clip corresponding to a selected channel in response to a terminating action by the user.

Digeo has added broadband video capabilities to its high-priced Moxi HD DVR, allowing users to access the likes of YouTube, Hulu and Netflix on their big screens through the device. The cable-ready set-top box uses the PlayOn digital media server software to access the popular web video hubs. Typically, the PlayOn software costs $39.99, but the service is available to Moxi users for no extra charge. Which is good, since the device already comes with the steep price tag of $799. Digeo justifies the high cost by saying that there is no subscription fee associated with Moxi (unlike TiVo, which carries a monthly service charge). Digeo also added the MoxiNet web browser, home automation controls, Flickr integration and DLNA certification to the HD DVR. By including the likes of Hulu et al., Moxi is looking to make a one-stop viewing shop for all your content needs, combining cable, PC and web video into one box. But does it add enough value to justify the steep price? You can access Netflix and YouTube on a host of other, far less expensive devices, and the allure of Hulu on your TV is to save money by not paying for cable. But such quibbles over price most likely don’t concern the premium market Moxi is going for. Digeo only sees its market for the Moxi as 12-15 million cable subs. Last year, Digeo laid off half its staff, changed CEOs and dropped some of its product offerings to refocus on the Moxi HD DVR.

Calling Digeo‘s Moxi HD DVR a DVR is sort of disingenuous. Sure, it can record and play back TV, but it can do so much more than that. The fact that the Moxi can do so much, however, is both its greatest strength and its greatest weakness. The Moxi’s many features include a dual-tuner DVR (multistream cableCARD required) with 500GB of storage. You also get the ability to view Flickr photos, movies from Netflix, and content from online video sources including Hulu.com, CBS.com and Amazon Video on Demand . In addition, you can connect the Moxi to your home network to play video content stored locally. You also can listen to music from Rhapsody, play games and browse select web sites. Still, the Moxi is, at heart, a DVR. And this is, sadly, where the device underwhelmed me. You can record two shows at once, schedule recordings online, and pause and rewind live TV — all the things a DVR should do. It does them capably, but accessing the DVR features can be a hassle, because of the Moxi interface. Some people love the interface (it won an Emmy), but it didn’t wow me. All of the menu options are laid out in a horizontal bar. When you select an item, its options are then shown vertically. When you want more options, those are shown horizontally. Once you get used to the layout, finding what you want is easy. Backtracking, however, is not. I repeatedly found myself trying to exit menus to no avail. And if you want to get to the DVR functions, you often have to scroll through several menu items just to do so. I wish there was a dedicated button on the remote that would take you right to the DVR features. And about that remote: It has two sets of directional buttons. One for fast-forwarding and rewinding content, another for navigating menus. Why not just have one set of buttons that handle both features? If you want to watch Internet-based content, you’ll need to download the PlayOn media server app (a license is included) to a computer on the same network as the Moxi. Once the PlayOn app is running, you can watch titles from your Netflix Instant Watch queue. In my tests, movies started immediately and looked very good. Hulu and YouTube clips — even in HD — also looked great. But navigating through the content in the Moxi’s vertical/horizontal/vertical menu structure can be a challenge, especially when accessing content from a site — like Hulu — that doesn’t use that same format difficult. The Moxi also plays content stored locally on your network, in theory, anyway. The Moxi found files stored on my network, but wouldn’t play any of them back due to file incompatibilities. The folks at Moxi admit that format support is limited (it supports MPEG-2 and WMV files, as well as MPEG-4 and H.264 files that have been transcoded), and say they plan to beef it up in the future. If you or your friends have photos on Flickr, you can view them from the Moxi. And you can do so while playing music from the Rhapsody music service (with a $12.99-per-month subscription) in the background. I really liked the Rhapsody integration; it’s a great way to listen to music in the living room. In addition, you can browse through MoxiNet, a pre-packaged set of web news stories. You can also use the Moxi to visit other sites by adding them to your account; you do so by visiting Moxi.com on your computer. Moxi says web browsing is handled this way so users can make a conscious decision about which sites they’d like to view on their TV screen — and which ones they can navigate without a keyboard. As you might expect, all of this functionality comes with a price: $799. That may seem like a lot — and it is, especially when you consider that you can get an HD DVR from your cable company for anywhere from $10 to $20 a month. But when you compare the Moxi HD DVR to its closest rival, the TiVo HD XL, the price is competitive. A TiVo HD XL goes for $599, but doesn’t include service; lifetime service is $399. The Moxi comes with the service included. If all you want is a basic DVR, you’d be better served by renting one from your cable company. But if your entertainment needs go beyond recording TV, Moxi has you covered. If they could beef up the file format support and make the DVR a little easier to access, I’d be sold.

I would love to hop on the *Google* TV bandwagon. It sounds like a fun ride with lots of great company and exciting plans. But it’s a hard jump to make given how many internet/web/connected TV bandwagons I’ve seen crash and burn or simply fizzle between the cable and consumer tech industries. The constellation of big names Google (NSDQ: GOOG) has as partners — Sony (NYSE: SNE), Logitech, Intel (NSDQ: INTC), Dish, Best Buy — helps build momentum but is no guarantee of success. Anyone remember Intel Viiv? Web TV? Joost? Yahoo (NSDQ: YHOO) Connected Life? Paul Allen’s Wired World? The myriad set-top boxes and streaming devices? Apple (NSDQ: AAPL) TV? Digeo? Insert your own examples here. They were either ahead of their time, not ready for prime time, or in some cases, not worth the time. Maybe the best thing going for Google TV is it wasn’t announced at CES. I’ve been having Las Vegas flashbacks (the tech-hangover kind, not the tiger-in-the-bathroom kind). One vivid memory is of sitting on the crowded floor in a booth during a 2006 press conference so big even the overflow was full for the — long drum roll — unveiling of the Google Video Marketplace. That turned out to be a bigger payday for the YouTube founders than for Google and its partners. Instead, long-rumored Google TV was unveiled at Google I/O in front of 5,000 or so developers and a remote audience following by streaming video. Google CEO Eric Schmidt was speaking to both when he talked about what it took get there. “We’ve been waiting a long, long time for this day. It took a lot to make this happen. It took the internet. It took extraordinarily fast CPUs, DSPs, a whole new architecture around software, open source and all the platforms that you’ve seen.” He added a dab of humility: “It’s much harder to marry a 50-year-old technology and a brand new technology than those of us from the brand-new technology thought.” But just a dab, mind you. Schmidt has decided Google is ready not only to make it happen, but in the immortal words of Tim Gunn, “make it work.” — Multiple paths: Google isn’t betting it all on one device or, it appears, price range. Sony will provide the one-stop experience with Sony Internet TV, offered through a sleek HDTV with Intel Atom processing power and a wireless QWERTY remote or a set-top box with a Blu-ray Disc drive. Logitech, already in the living room via Harmony remotes, is planning a companion set-top box that will “seamlessly” add Google TV to current HD sets through an HDMI port, and “an intuitive controller.” It should be a lot less expensive than buying a new set, especially for those who upgraded to HD only recently. Logitech estimates there are roughly 60 million HD sets being used in the U.S. For the basics, Logitech says a broadband connection and HDMI port are enough; for full capability, you need a satellite or cable set-top with HDMI output. (That last — and the deal with Dish — are important when it comes to the ability to refute claims Google is trying to cut out subscription TV, and offer the broadest spectrum of video/TV possible.) Google also says it will make the code available for others to build their own platforms. — Android & Chrome: The combined pace of Android activation — now more than 100,000 a day — and innovation is a major plus. The spread of Android and its availability across carriers can’t be overvalued; it provides reach and exposure. The innovation — providing it works as promised — not only makes Android devices into remotes; it enables communication back from the TV to the device. It’s also a streaming source, which means (see caveat above) that users should be able to push content on the phone to the TV. The Android Marketplace and the upcoming Chrome Web Store, along with the way they’re supposed to work together, add to the potential. — Easy access: Google TV promises to be the simplest way yet for 10-foot access to the web. My own living-room setup includes a Media Center PC with Windows 7 connected to the HD set. The lack of the right PC-TV remote keeps it from being used as much as it should. Google says it can solve that and provide a superior browser/search experience that lets users make the most out of internet-connected TVs — and all those web/Android apps. I can believe that; 10-foot Firefox doesn’t really cut it. To be fair, I haven’t done a lot to make my own set up a better experience. Google’s point is I shouldn’t have to. — Retail partner: The surviving consumer-electronics big-box chain has made a major commitment to new technology and serious investment in showcasing TVs. It also sells handsets for all major U.S. carriers. It’s been a limited, but good retail outlet for Apple and its management gets the value of social media so it’s not likely to let glitches turn into brush fires. — Open: I’ll let others more schooled in the nuances get into how really open this all will be but it’s based on Google Chrome and Android, both open source, and will use Flash. (Played up against Apple’s control issues, as it was almost too intensely during the keynote, it looks really open.) Developers can start optimizing sites now but the developers’ kit and the API won’t be released until after launch. The Google TV unveiling emphasized search and navigation, but the Chrome Web Store demo featured Clicker.tv, a 10-foot programming guide with navigation designed to work on the screen with various devices as remotes. Still, Google runs the risk of looking very old-school Microsoft (NSDQ: MSFT) when it comes to favoring its own apps and services, especially those baked into the turn-on experience. — Lotta moving parts: The very things that could make Google TV cool and functional rely on a lot of partners and a lot of elements coming together. If there’s not an algorithm somewhere that shows the odds of success based on the number of disparate elements needed to make it happen, there should be. — Best Buy as retail partner: Over the years I’ve gone to Best Buy in search of any number of hot new items or services that either aren’t displayed to advantage or aren’t understood well enough by the sales staff. When a Blue Shirt gets it and can explain, it’s great. When they don’t, the sale is at risk or a potential boomerang. From my perspective, launching with exclusive sales through Best Buy hasn’t always been a plus. It’s supposed to guarantee some quality control and sales awareness but sometimes cuts off buying opportunity and interest. — Iteration for non-geeks: Sony chief Sir Howard Stringer talked up the ability to keep upgrading Sony Internet TV without changing the box or TV. That’s a big plus. But even geeks get frustrated when developers and manufacturers use that ability as an excuse for bugs. Non-geeks, who might barely be aware that their cable box gets updated, are still going to see that TV as a TV, not as a computer. Getting them used to an “evolving” TV idea is going to take time and minimal screw ups. Like Apple and Microsoft, Google, despite its heft and brilliance, doesn’t always win or meet the frequent assumptions that anything it does is an “x-killer.” Our archives are full of examples. Sometimes, as was the case with YouTube, it buys the competition. Sometimes it just admits defeat one way or another. Then again, Google also succeeds a lot, which is why its moves are followed so carefully. This one has the potential to fall in either category.

A new iPad app called Fayve, making its debut on Thursday, will join a crowded field of digital tools that help people discover movies and television shows. But this one is different — having started out not as a product but as a way for Microsoft co-founder Paul Allen to navigate his own giant collection of films and shows. Yes, that’s right — when you’re a billionaire tech mogul, you’re not limited by off-the-shelf apps. Allen has a staff of people coming up with technologies and tools to help manage his stuff and address his challenges. And sometimes the things they come up with turn out to have broader appeal. That’s the case with Fayve, which indexes content from Netflix, Hulu, iTunes, and other online video services. It recommends content based on ratings by the user, their social activity (such as Facebook likes), their wishlist items, Netflix queue, and also the preferences of the user’s Facebook friends, among other inputs. “Paul has probably one of the world’s largest private digital collections of movies, music and TV shows. He wants to watch and listen to these things at his fingertips,” said Chris Purcell, the vice president of technology for Allen’s Vulcan Inc., via phone today. “We built Fayve to sit on top of his collection, to give him exactly that experience.” Although the core of Fayve was originally developed for Allen’s personal use, his technology team went through extensive development and design work to get it ready for public use as an iPad app. The app is free, but this is a business venture, making money through revenue sharing from the different video services to which Fayve directs users. Fayve uses a carousel approach that sorts movies and shows based on filters, such as genres, recommended items, actor or actress, new arrivals and other variables. Fayve can also be used to look up show times and buy movie tickets at theaters. Apart from a reference to “favorites,” the name of the app is an homage to Allen’s mom, Faye, who passed away earlier this year. It’s far from the first foray into Hollywood-oriented businesses for Allen, who also was an investor in DreamWorks and the backer of set-top box maker Digeo, among many other investments and ventures. The iPad app is set to go live on Thursday in the App Store. Update: The app is now available for download here. Allen’s team is also planning versions for Windows 8 and Android. Here’s an FAQ on the Fayve site, and more screenshots from the app. (Click any image for a gallery.)

It has been taken for granted that cell service faces inevitable slowdowns as more users look to grab more data from ever-more-crowded cell towers using a limited amount of wireless spectrum. It’s why even ultra-fast LTE service starts to bog down in dense urban areas as more and more people adopt data-hungry smartphones and tablets. To avoid interference, each device essentially takes turns grabbing the information it needs, meaning that as more users try to connect, the speeds get further away from the theoretical maximum. The only answers served up so far have been to adopt faster network standards, use so-called “small cells” to boost coverage or add spectrum. But tech industry veteran Steve Perlman says the industry has gotten it wrong. His 12-person startup, Artemis Networks, proposes carriers use an entirely different kind of radio technology that the company says can deliver the full potential speed of the network simultaneously to each device, regardless of how many are accessing the network. The technology creates a tiny “pCell” right around the device seeking to access the network and sends the right signals through the air (via licensed or unlicensed spectrum) to give each of the tiny cells the information it needs. Think of a pCell as a tiny bubble of wireless coverage that follows each device, bringing it the full speed of the network but only in that little area. The signals are sent through inexpensive pWave radios and, because Artemis technology doesn’t have to avoid interference, the radios can be placed with far more freedom than cell towers or small cells. It also means that, in theory, the technology would be able to bring high-speed cellular service even in densely packed settings like stadiums — locations that have proven especially thorny for traditional cellular networks. Artemis plans to demonstrate the technology publicly Wednesday at Columbia University. In demos, Artemis has been able to show — in only 10MHz of spectrum — two Macs simultaneously streaming 4K video while nearby mobile devices stream 1080p content, a feat that Perlman says would not be possible with even the best conventional mobile networks. The company has been testing the network in San Francisco, and Perlman says that by late this year the company could have a broader test network here up and running. The plus is that, while the system requires a new kind of radio technology for carriers, it is designed to use existing LTE-capable phones, such as the iPhone or Samsung Galaxy S4. The pCell technology can also be deployed in conjunction with traditional cellular networks, so phones could use Artemis technology where available and then fall back to cellular in other areas. That said, while the infrastructure is potentially cheaper than traditional cellular gear, Artemis faces the task of convincing carriers to invest in a radical new technology coming from a tiny startup. Perlman is no stranger to big ideas, but he has also struggled to get mainstream adoption for those technology breakthroughs. After achieving fame and success selling WebTV to Microsoft, Perlman aimed to change the pay-TV industry with Moxi but found that most of the large cable and satellite providers were not eager for such disruptive technology. Moxi was eventually sold to Paul Allen’s Digeo and the combined company’s assets eventually sold to Arris in 2009. With OnLive, Perlman proposed using the cloud to deliver high-end video games streamed to users on a range of devices, a technology it showed off at the D8 conference in 2010. Despite cool technology, though, Perlman’s venture struggled and abruptly laid off staff in August 2012. The business as it had been initially founded closed, though its assets did get sold to an investor who is still trying to make a go of things under the OnLive banner. Perlman insists he has learned from the obstacles that kept him from making those past visions into market realities. “The challenges are always when you have reliance or dependencies on other entities, particularly incumbents,” Perlman said. That, in part, is why Artemis took its technology approach and made it work with traditional LTE devices. Perlman said he knew getting the Apples and Samsungs of the world to support it was a nonstarter. So how will he convince the AT&Ts and Verizons of the world? Perlman said a key part there was to wait to launch until the need for the technology was clear. “We’ll wait until they get congested and people start screaming,” Perlman said. Artemis is so far funded by Perlman’s Rearden incubator, though Perlman has met with VCs, even briefly setting up a demo network on Sand Hill Road to show off the technology. Richard Doherty, an analyst with Envisioneering Group, says Artemis’ pCell technology seems like the real deal. “[The] pCell is the most significant advance in radio wave optimization since Tesla’s 1930s experiments and the birth of analog cellular in the early 1980s,” Doherty said in an email interview. “I do not use the word ‘breakthrough’ often. This one deserves it.” As to whether and when cellular carriers bite, Doherty acknowledged that is the $64 billion question. “If one bites, none can likely be without it,” he said. If none do, he said Artemis can use pCell in conjunction with Wi-Fi to demonstrate the promise and challenge operators. “My bet is a handful will run trials within the next year.”

Updated 12:09 p.m. PDT with additional information and background and at 12:42 p.m. PDT with comment from the plaintiffs. Microsoft co-founder Paul Allen fired a patent shot across the bow of several prominent technology companies Friday, suing Apple, Google, Facebook, Yahoo, and others over patent claims. Allen's firm Interval Licensing filed a lawsuit in federal court alleging that the above companies, as well as AOL, eBay, Netflix, Office Depot, OfficeMax, and Staples, are violating patents he received for several Internet technologies while leading Interval Research, now out of business. The case was filed in U.S. District Court for the Western District of Washington, based in Seattle. Interval said in a press release that "the patents in the lawsuit cover fundamental web technologies first developed at Interval Research in the 1990s, which the company believes are being infringed by major e-commerce and web search companies." David Postman, a spokesman for Allen, said this is the first time that patents related to Interval Research's work have been litigated. Postman wouldn't comment on whether licensing discussions had taken place with the defendants prior to the filing of the lawsuit, but did say that all companies were informed that Interval held "patents of interest." The companies targeted were done so because of their work in e-commerce and search, Postman said. For example, Interval included as an exhibit in its lawsuit a screen grab of a very early "About Google" Web page from 1998 that lists Interval Research Corporation as an outside collaborator. One may wonder why Allen's former company--Microsoft, which operates the third-leading search engine in the U.S. and now provides search technology to Yahoo--was not cited in the complaint. Postman said he would not discuss litigation strategies but emphasized that Interval is not necessarily done with these patents; in that, it might seek to widen the circle of defendants at a later date. Representatives for Apple and Google did not immediately return requests for comment. However, Facebook spokesman Andrew Noyes said "We believe this suit is completely without merit and we will fight it vigorously." The story was first reported by The Wall Street Journal. Four specific patents are being cited in the case, according to Interval's release: No. 6,263,507, "Browser for Use in Navigating a Body of Information, With Particular Application to Browsing Information Represented By Audiovisual Data." No. 6,034,652, "Attention Manager for Occupying the Peripheral Attention of a Person in the Vicinity of a Display Device." No. 6,788,314, "Attention Manager for Occupying the Peripheral Attention of a Person in the Vicinity of a Display Device." No. 6,757,682, "Alerting Users to Items of Current Interest." Allen founded Microsoft with Bill Gates ages ago, but hasn't played a prominent role at the company in years. He has since invested in a number of ventures in both the technology and entertainment worlds, and organizes his business and philanthropic activities through a firm called Vulcan. Digeo, an Allen-backed maker of DVR technology, aggressively asserted patents against various companies about five years ago in various lawsuits against PalmSource, Audible.com, and Gemstar. Digeo was sold to Arris Group in 2009. A copy of the complaint follows below:
