February 20 de 2000 Video Quality - Optimizing your video experience Tips on optimizing your video experience.

Bandwidth While you probably already know that you need a broadband connection to use ooVoo, did you know that not all broadband is created equal? Even on the same connection, your bandwidth (the amount of data that can be transmitted in a fixed amount of time) may vary based on factors such as the amount of traffic on the network, the number of people using your Internet connection, and whether you are downloading or streaming something else. Below are three measurements of your connection speed that will influence your video quality. Downstream - This is the amount of bandwidth you have coming to your computer from the Internet. Think of this as how wide the road is coming to your house. The more downstream bandwidth you have, the wider the road and the more traffic that you can accept. You should have a minimum of 128kbps downstream bandwidth; for the best quality video and for multi-person conversations you should have 512kbps Upstream - This is the amount of bandwidth you have going from your computer to the Internet. Think of this as how wide the road is going from your house. The more upstream bandwidth you have, the wider the road and the more traffic that you can send. You should have a minimum of 128kbps upstream bandwidth; for the best quality video and for multi-person conversations you should have 512kbps Latency (delay) - This is the amount of time it takes for the traffic you send to reach its destination. To use the previous analogy, even if you have a wide road going to and from your house, if your car is moving slowly on the road, it will take a lot longer to get where you are going. If you notice it is taking a long time for your friend to respond, or that you are talking over each other, this is probably being caused by high latency. Your latency should be below 250ms. Latency problems are often caused by network congestion, if you experience problems, try ending the video conversation and starting it again. To test your bandwidth, you can visit one of the sites below: DSL Reports Speakeasy - Speed Test Equipment Webcam - While a webcam is not necessary to run ooVoo, your friends will not be able to see you during your conversation if you don't have a webcam. When buying a webcam, be sure to get one that will produce good quality video. Tip: You can often judge the quality of video by the price. A $10 webcam will probably not produce very good looking video while a $100 webcam is probably overkill. Something in the $30-$50 range should work just fine. Headset - Although ooVoo uses echo cancellation software to improve the sound quality of your conversation, the built-in speakers and microphone on your computer may still cause some echo. We therefore recommend using a headset (headphones with a microphone) for the best audio quality. Tip: If you have a microphone built into your computer or laptop, just plug in a set of regular headphones to get rid of any echo. Computer - Even if your computer meets the system requirements for using ooVoo, you may notice problems with the video if you are on an older computer, or have a lot of programs running at one time. Tip: Close all unnecessary applications you may be running and if you are using a laptop, make sure it is plugged into a power outlet. Lighting Good Lighting - Because cameras are less sensitive to light than the human eye, it is important to have good lighting when you are using ooVoo. If your video looks dim, grainy or washed out, try adjusting the location and brightness of your lighting. Below are some common problems caused by lighting and some suggestions to fix them: Dim video - There isn't enough light in your room. Try turning on more lights, or move to an area where there is more light. Dim image - The room is bright but your image is dim - This could be caused by having a bright light source behind you. The camera adjusts it's sensitivity to the background instead of you. Try positioning yourself so the light source is in front of you. Grainy video - While this could be caused by a low quality camera, it can also be caused (or made worse) by not having enough light. To compensate for the lack of light, camera's often adjust their sensitivity which creates more grain or "noise" in the image. Try turning another light on, or sitting closer to and facing the light source. Video looks choppy - This can be caused by not having enough light in your room, but can also be caused by not having enough bandwidth. Try turning on more lights and if you still have the problem, read the section above called "Bandwidth". Your image looks washed out - This is usually caused by a light that is too intense (example: having a light shine directly at your face). Try dimming the light, or reflecting the light off a light colored surface, like a white piece of paper on your desk. Download

Old Microsoft vs New Microsoft ?

TECHNOLOGY. State of the Art

A Little Piece of Microsoft Aids Small Business By DAVID POGUE Published: February 14, 2008

Illustration by Stuart Goldenberg

So Microsoft is making a hostile bid forYahoo. Has it come to this? Is Microsoft's innovation engine so dead that the only way it can grow is to buy other companies? It's sad, in a way, because under the right circumstances, Microsoft, or pieces of it anyway, are still capable of fresh ideas and polished work. The company itself may be a massive fallen redwood tree, slowly rotting in an old-growth forest. But sprouting from that decaying Windows/Office log are little green start-up shoots. They prove that even if the bureaucracy has made Microsoft top-heavy and leaden, innovation still thrives in pockets. Nowhere is this old Microsoft/new Microsoft dichotomy more apparent than in the company's suite of online tools for small businesses, which reopened Monday in an improved 2.0 version (www.smallbusiness.officelive.com).

Multimedia Video Office Live Small Business.

What makes Office Live Small Business so compelling is its sharp focus on a single problem: that half the small businesses in America, and 70 percent of one-person businesses, don't even have Web sites. Obviously, the percentage that exploits Internet marketing tools like e-mail newsletters, search engine ads and online stores is even lower. Suppose you're among them. Suppose you train dogs, or translate documents, or retouch photos, or sell knickknacks on eBay, or make seashell jewelry. And right now, your idea of a marketing plan is taping up fliers in the grocery store. How are you supposed to get a Web site? Who will design it, and who will host it? Who do you pay to place search engine ads for you, and how will you know if they're working? How do you send out e-mail newsletters without being blocked as a spammer? And how will you know if that effort is paying off? And above all: how much is all this going to cost you? Office Live Small Business (O.L.S.B.) is a centralized Web site where you can set up all of those small-businessy things — a Web site, an online ad campaign, e-mail promotions, in-company communications — all by yourself, even if you're not very technical. For the first time, these big-league tools are within your reach, partly because you don't have to hire somebody to set them up and partly because many of them are free. The changes from the original 2006 version are apparent immediately. Internet Explorer used to be the required Web browser to set up your online presence, but now Firefox is O.K., too. And that means you can take advantage of Office Live even if you use (gasp) a Macintosh. That's the New Microsoft, baby. A credit card is no longer required to get started, either. You can start playing with the service by supplying nothing more than a name, e-mail address and ZIP code.

Office Live Small Business lets entrepreneurs set up a Web site and more. Most features are free.

There are no longer three different tiers of Office Live service, with different fees and different features; that's the Old Microsoft way (see also: Windows Vista). Instead, there's just one free service that includes a wide assortment of useful tools, plus a handful of á la carte extras. The freebies begin with a Web site for your business, complete with 500 megabytes of storage. Simple tools let you design clean-looking pages, with your choice of color and design themes, logo and photos, links, and so on, even if you have absolutely no experience doing this sort of thing. (You can see the results at, for example, whineranddiner.net, murphyoutdoors.com and ameliascakes.com — real sites created by actual Office Live users.) Microsoft hosts your site free, and also offers free analysis tools. With one click, you can see a graph of your site's traffic over time; where the visitors are coming from (for example, search engines or links from other sites); and even which Web browsers they're using. A number of useful Office Live features that used to cost you money are now free. For example, only paid subscribers enjoyed the ability to synchronize their Office Live address books and calendars with Outlook, so they could work on them when not connected to the Internet. That's now free to everyone. Similarly, if you wanted to design your own Web pages (or hire someone to do it) instead of using Microsoft's canned page designs, you used to have to pay; now that's free, too. As a bonus, you can now remove the small Office Live logo from your site — a welcome change. The old fee-based tiers also included a long list of features for the technically inclined: list managers that help you track employees, resources, reservations, and so on; project and time trackers; a document-sharing module; and collaboration tools for internal company discussion. Those are all free now.

Unfortunately, Microsoft giveth and Microsoft taketh away. The most famous feature of the original Office Live was the free domain-name registration. That is, your free Web site could have any dot-com name you liked — BobsFleabag.com, for example — and you also got 25 e-mail addresses to match (sales@bobsfleabag.com, info@bobsfleabag.com and so on). Those unheard-of perks are gone; after the first year, Microsoft now charges $15 a year for those custom domain names and e-mail addresses (at least for new members). If you decline, your free Web site will be stuck with a clunky name like bobsfleabag.accommodations.officelive.com. Nor is that the only way Microsoft intends to make money from this service. For example, there are small ads on the Office Live Web site (the one with the tools — not the site you create). Because these ads are aimed at you, the small-business owner, they're not especially bothersome, for the same reason that people don't mind, say, ads for cameras in a photography magazine. Meanwhile, Microsoft can charge advertisers more for these ads because they are, again, so targeted. Office Live offers an easy-to-use e-mail marketing system that includes newsletter design and address database. You can also track the results of your e-mail initiatives: how many people opened your mail, as well as how many clicked a link in it. Microsoft even does the e-mail sending for you, so your e-mail won't get blocked by your own Internet provider as spam. That's all free during the current testing phase, but Microsoft will charge a monthly fee after that. Ditto for the terrific build-your-own-online-store feature. You get a traditional online shopping cart, integration with eBay, and auto-calculations of shipping and even taxes (according to the buyer's state). But you'll pay $40 a month for this high-end luxury, plus a $30 monthly PayPal fee if you want to accept payment by credit card right on your Web site. (Otherwise, your customers will be shunted off to PayPal.com to complete the transaction.) PayPal charges about 3 percent of each sale either way. Finally, of course, you have to pay to place ads in the results of Web search sites; here again, Office Live tracks the results, making it crystal clear which of your ads are producing the best results. This, though, may be the goofiest part of Office Live. You can place ads only on Microsoft's search sites and Ask.com, which together represent less than 8 percent of search engine popularity. If you're going to advertise, you'd almost certainly prefer the exposure of the Big Two — Yahoo and Google — but they're not available through Office Live. Now, plenty of companies sell similar services individually: Web hosting, for example, or online marketing. But Microsoft claims to have no competition for Office Live's concept. Nobody else offers a complete one-stop self-contained unified Internet toolkit for small businesses — especially not at these prices. The result is exciting for two reasons. First, Office Live Small Business gives the nation's 25 million small businesses a chance to use the same online tools as the big boys. Second, Office Live Small Business has all the hallmarks of a start-up: innovative, focused, fast-moving, game-changing, quick to respond to customer feedback and nimble in recovering from mistakes. When was the last time anyone described Microsoft that way?
