TV Anytime or Place: The Sequel By DAVID POGUE Published: November 1, 2007 |
|
O.K., it's happened: we're officially old. When you sheepishly tell your children that you used to have to watch TV shows by sitting down in a certain place at a certain time well, you know you're old. First came the TiVo and its ilk, eliminating the bit about sitting down "at a certain time." Then came the Slingbox from Sling Media, which obliterated the need to be "in a certain place." Later, SlingPlayer Mobile software for cellphones even wiped out the part about "sitting down." Of course, the Slingbox isn't nearly as famous as the TiVo; you may not even have heard of it. In that case, saying that the new Slingbox Solo has a lower price ($180) than its predecessors and has built-in jacks for high-definition gear probably won't mean much to you. In that case, a primer is in order. The Slingbox's purpose in life is to transmit whatever is on your TV to your laptop or smartphone (like a Treo or Windows Mobile phone) across the Internet. The point, of course, is to allow people who travel to another room, another city or another continent to view all the channels and recordings that they're already paying so much money for at home. It comes in handy when you want to watch TV upstairs, but your fancy high-definition TiVo is downstairs. It's also great when you're in a hotel room, bristling at paying $13 for a movie when your video recorder back home is a veritable Blockbuster. And Slingboxes are also a blessing when you are overseas and longing for the news, or the sports broadcasts, of your hometown. There are a few other ways to perform a similar stunt, but none with the Slingbox's high video quality, super-simple setup and ability to display both recordings and live TV. The new Slingbox Solo is tiny; its trapezoidal shape is meant to evoke the shape of a gold ingot, and it's now about that size, too (9 by 4 by 2 inches). That's about half the size of its predecessor, the Slingbox Pro. (The Pro is still available, however for $230, plus $50 for an accessory if you want to connect to high-def equipment. The Pro lets you connect up to four video sources TiVo, satellite box, Apple TV, DVD player and so on and switch among them by remote control. The Solo, as its name implies, connects to only one. For most people, that's the TiVo, satellite box or cable box.) If you're the kind of person who is terrified by the tangle behind your TV set, the setup is no joyride. For anyone else, though, it's not bad. You plug your video source into the Solo's inputs: component cables (for HDTV gear), S-video or composite cables. If a video source has only one output a cable box, for example you'll be grateful that the Solo also has outputs that pass the signal on to your TV. (Another existing model, the Slingbox AV, does not.) In other words, you can wire the Solo in between your cable box and your TV. More Articles in Technology » |

You must also connect the Slingbox to a broadband Internet connection. For most people, that means connecting the Slingbox to a home router. This may be the stickiest part of the installation, since your router is probably in the basement, closet or office not next to the TV. And the Slingbox isn't wireless. At this point, you could buy a really long Ethernet cable and thread it through the walls, from Slingbox to router. Sling reports that some people have luck with wireless transmitters, but it recommends its own SlingLink Turbo powerline transmitters ($80 a pair). They use your home's electrical wiring to carry network signals. You just plug one SlingLink into an outlet near the TV, and the other near your router. And presto: network jacks within a foot of where they need to be. Finally, you run the setup software on your Mac or PC. It's supposed to be effortless and automatic, but I wasn't so lucky; the setup software told me that my oddball router wouldn't permit automatic configuration. (It's a Linksys, probably the most popular brand on earth. Some oddball.) Fortunately, the company's Web site (slingmedia.com) offers step-by-step instructions for dozens of router models, mine among them; unfortunately, the illustrations didn't match the hideous configuration screens that I was seeing. Nonetheless, it was enough help to guide me through changing some parameters like IP Address, Port Range Forwarding and Service Management. When it was all over 20 minutes I was watching live TV on my laptop over my home's wireless network. On your virtual TV screen, you see a perfect replica of the remote control; Sling has re-created on-screen remotes for over 5,000 pieces of video gear. Every button takes a second or two to respond, but it's still pretty amazing to think that as you sit in Singapore, you're controlling your TiVo in Tulsa. The video quality depends on the network speed at both ends. When you're in your house, connected over your home network, the picture quality is superb: clear, crisp, perfectly smooth (though never quite as good as on the TV itself). Across the Internet, the picture is a good deal softer, more like a VHS recording. It's still eminently watchable; you just don't want to watch special-effects blockbusters this way. For $30, you can even buy a tiny copy of the SlingPlayer software that runs on a growing list of smartphones, including those that run Windows Mobile, PocketPC, the Palm OS (like the Treo and Centro families) and the Symbian OS (many Nokia smartphones). BlackBerry and iPhone versions are in the works. (The iPhone's glorious screen should make a terrific TV while you're connected in a Wi-Fi hot spot. Unfortunately, the AT&T data network is too slow for a satisfying video transmission when you're beyond a hot spot.) Now, a cellphone's Internet connection generally isn't fast enough to permit the kind of picture quality you would get on a laptop. But even though there aren't nearly as many pixels in the picture, they're shrunken down so tightly on the phone screen that they look sharp anyway. Incidentally, don't think that because the Solo accommodates high-def gear, you get a high-def picture on your laptop or cellphone. You don't. You do, however, get a better picture when watching HDTV broadcasts, especially when you're viewing on your home network (rather than across the Internet). There's really only one prominent drawback of the Solo, and that's that it commandeers the whole TV setup. If you're watching in Wilmington or changing channels from Chattanooga, whoever is at home trying to watch TV will be forced to surrender to your tastes. (The more expensive Pro version lets you split the incoming cable signal so that the homebody at least has an independent choice of basic cable channels.) In that regard, the Solo's name takes on even more relevance; this box is best suited for singletons. Otherwise, though, the Solo does well what the Slingbox has always done well, but now for less money, in less space and with more flexibility. Nor is Slingbox finished with its upgrading binge; in a month, the company says, it will unleash a free software update that lets you pause, rewind and then fast-forward the incoming video transmission, much the way TiVo owners can. It will also let you record short clips and post them to Sling's Web site, legal snarls permitting. So, you can imagine today's young people explaining TV to their offspring. "When I was your age, we needed a box to place-shift our TV...." E-mail: pogue@nytimes.com |
Google anuncia plataforma en "open source" para celulares y PDA´s.
By Marguerite Reardon and Elinor Mills Staff Writer, CNET News.com Published: November 5, 2007, 8:13 AM PST Last modified: November 5, 2007, 10:40 AM PST Google unveils cell phone open software plattform and alliance Update: Google's cell phone strategy took shape Monday with the announcement of a new open software platform and an alliance of wireless heavyweights that will help form the development community for the planned phones. |
Mobile with Google "free" software. |
Google has long been rumored to be working on software for cell phones that would integrate its applications. On Friday, CNET News.com reported that Google's plans went beyond simply developing software and instead included a whole consortium of companies working to develop an open platform cell phone application. "Today's announcement is more ambitious than any single 'Google Phone' that the press has been speculating about over the past few weeks," Google CEO Eric Schmidt said in a statement. "Our vision is that the powerful platform we're unveiling will power thousands of different phone models." Google officially unveiled Android, the new mobile phone software, during a press conference Monday morning. Thirty-four companies have said they will join the Open Handset Alliance, a multinational alliance that will work on developing applications on the Android platform. Members of the alliance include mobile handset makers HTC and Motorola, U.S. operator T-Mobile, and chipmaker Qualcomm. The Android platform consists of an operating system, middleware, a user-friendly interface, and applications. Consumers should expect the first phones based on Android to be available in the second half of 2008, Schmidt and others said on the conference call. The Android software stack is expected to provide handset makers and wireless operators an open platform they can use to develop innovative applications. The new software will compete directly with smartphone software from other companies like Apple, Microsoft, Nokia, Palm, and Research in Motion. Unlike some of these mobile operating systems, Android will not be tied to a specific device. Instead, the software will be able to work on a broad array of devices from handset makers such as Motorola, HTC, Samsung, and LG just to name a few. A 200MHz ARM 9 processor is the minimum requirement for cell phones, said Andy Rubin, Google director of mobile platforms who co-founded the mobile software company called Android that Google acquired in 2005. The platform will be flexible, compatible with small or large screens, keyboards and other input methods, he said. |
"The user experience is top notch...We will see when the software development kit is available in a week," Rubin said. "Google will be providing some hosted services that make it very easy for third-party developers to distribute their services and content" via a USB or memory card or "over the air." He added that more information about system requirements will be available when the software development kit is released. Asked whether Android will be targeted at smartphones or lower-cost phones, Qualcomm Chief Executive Paul Jacobs said the company was focusing on its 7225 chipset and "using that to drive smartphones into the mass market price points under $200." The idea is that through the developer's alliance, handset makers and cell phone operators will be able to develop more user-friendly services and devices that help bring more of the Internet's functionality onto mobile devices. And because of this open model, the companies involved also hope that by scaling the development, advanced functionality will be able to hit the market for less expensive mobile devices that will have more compelling and rich Internet services with more user-friendly interfaces. "Our participation in the Open Handset Alliance and integration of the Android platform in the second half of 2008 enables us to expand our device portfolio into a new category of connected mobile phones that will change the complexion of the mobile industry and re-create user expectations of the mobile phone experience." Peter Chou, chief executive of HTC, said in a statement. Companies in the alliance plan on releasing an access software development kit next week. |
