First HD Wireless Video Extension over 802.11n

$2,300 for a transmit/receive pair

Avocent Announces the Digital Signage Industry’s First IEEE802.11n Based HD Video Extension and Distribution System

New Emerge® MPX1550 multipoint extenders raise the bar for wireless video distribution products

HUNTSVILLE, Ala., November 10, 2008 – Avocent Corporation (NASDAQ: AVCT), the recognized leader in managed audio video wireless extension networking products for professional audio video applications, today announced the MPX1550 wireless extender.

This breakthrough product combines Avocent’s field-proven MPX1500 wireless video distribution technology with the latest in WiFi advancements, IEEE802.11n MIMO-based radios, thereby raising the bar for wireless HD video distribution systems in terms of visual acuity, transmission distance, and noise immunity. With the MPX1550 system, deployment of a single stream of media to many displays can be accomplished in minutes, even under the most challenging of conditions, with a degree of reliability and quality that rivals a dedicated source device at each and every display.

Unlike multiple source devices, however, video and audio remain in lockstep across all displays, failure-prone moving parts are kept to a minimum, and software licensing costs are greatly reduced. Equally important, all devices in the media network are remotely manageable using the MPX1550 extender’s onboard Web interface, which is accessible via a dedicated control LAN interface.

“As the number of public displays continues to mushroom, the ability to deploy these displays in a rapid yet cost-effective manner has become a key differentiator for signage network providers,” said Mitch Friend, senior vice president and general manager of Avocent. “It has also become clear to us that content requirements differ among various deployments such as retail, institutional and way-finding signage applications. Characteristics such as visual acuity, resolution of motion and still images tend to vary. To handle the most demanding applications, we’ve added the MPX1550 system to our product offerings. By adding the 802.11n support to our product line, customers are now able to choose the extender that is best suited for their application.”

Emerge MPX1550 extenders are widely deployed for a variety of professional video applications, such as digital signage – providing panels with live content, entertainment and advertising in retail outlets, theaters, restaurants, airports, gas stations, and other venues. The Emerge MPX1550 extenders offer both wired (over IP) and wireless operation, including distribution of both HD and SD video signals from a single transmitter to a cluster of receivers. The MPX1550 system is uniquely optimized for both full motion video and still images.

The extenders support digital and analog video signals, providing support for a wide range of DVI, HDMI, VGA and component source and display devices. MPX1550 extenders also perform analog to digital conversion as needed to match dissimilar source and display devices. For additional control over source and display devices, the MPX1550 extenders also forward serial and IR signals. Support for HDCP ensures that even protected content can be distributed through signage networks in a secure and compliant manner.

The Emerge MPX1550T wireless transmitter and Emerge MPX1550R wireless receiver are available this month at a MSRP of $1,145 each.

Google vs. Dolly Parton

The white space battle makes the NY Times....

Game Over- FCC Goes White Space Google

FCC votes to turn empty TV spectrum into wireless Internet access

The plan allows high-tech firms such as Google and Microsoft to develop a new generation of devices that will use the 'white spaces' between channels to go online.

By Jim Puzzanghera November 5, 2008

Reporting from Washington -- Federal regulators on Tuesday approved the largest ever expansion of wireless Internet access, unanimously backing a controversial plan to allow a new generation of devices to use the empty airwaves between television channels to go online.Dubbed "Wi-Fi on steroids" by its supporters in the high-tech industry, the plan promises to offer wireless Internet service across America -- most likely for free -- and spur new systems for transmitting video and other data between devices in homes.

It overcame staunch opposition from the entertainment industry, which is worried that the Web-surfing devices will interfere with TV broadcasts and wireless microphones.Although expected to be slower and possibly less secure than commercial broadband services from cable and phone companies, the new Internet connections will ride on the highest-quality broadcast airwaves, which are able to carry signals long distances and easily penetrate trees and walls.For decades, those government-owned airwaves have been reserved for TV stations.

But the Federal Communications Commission, in a 5-0 vote intended to increase the reach of high-speed Internet access, approved a plan advocated by public interest groups and technology companies, including Google Inc. and Microsoft Corp., to allow the use of the spectrum by new laptops, mobile phones and other gadgets with built-in equipment that are expected to hit the market in about two years.

"Consumers across the country will have access to devices and services they may have only dreamed about before," FCC Chairman Kevin J. Martin said.

The high-tech firms say the so-called white spaces of the airwaves that lie between the broadcast TV channels have the potential to provide revolutionary new wireless services that people could use for free -- unlike the spectrum leased by the government to cellphone companies, which then charge customers to access it.

Google Chief Executive Eric Schmidt and Microsoft co-founder Bill Gates personally lobbied FCC commissioners to open up access to the vacant channels, which range from about a third of the TV airwaves in major cities such as Los Angeles to three-quarters of the airwaves in rural areas.

These companies will have to build the infrastructure to connect the airwaves to the Internet, such as installing transmitters on existing cellular towers. Although they could charge users for those connections -- in the same way that some coffee shops charge for access to their Wi-Fi hot spots -- Google and others are expected to offer them for free, recouping the cost through sales of white-space-enabled devices and online advertising.

"This is a clear victory for Internet users and anyone who wants good wireless communications," Google co-founder Larry Page said.

Broadcasters fiercely fought it, warning that the new devices could cause some viewers to lose their TV signals because of interference. The issue is of particular concern because broadcasters must switch to all-digital signals in February. With traditional analog TV stations, interference causes static or fuzziness. But broadcasters say digital pictures can freeze or be lost entirely if another signal is broadcast on or near the same channel.

"The commission chose a path that imperils America's television reception in order to satisfy the 'free' spectrum demands of Google and Microsoft," said David Donovan, president of the Assn. for Maximum Service Television, an engineering trade group of TV broadcasters.

Representatives of sports leagues, musicians and large churches have also complained about potential interference from the new Internet devices and lobbied against the changes. They worry, for example, that one of these devices in a concert-goer's pocket would interfere with the performer's wireless microphone.

The FCC's field tests of early prototypes provided by Microsoft and other companies produced mixed results, with some of the devices failing to sense and avoid broadcast signals. Broadcasters said those results showed that the technology wasn't ready.

But FCC officials said the tests showed that it was possible for devices to use the airwaves without interference.

The devices will operate at low power and will only be able to use channels 21 to 51, where there are fewer TV stations. The FCC will give preference to devices that use technology to determine a user's location and then avoid TV channels operating there based on a special database, rather than devices that try to sense and avoid TV signals. Devices that use sensing technology will have to go through more rigorous field testing before being certified.

The FCC also will create a safe zone around large sporting and performance venues, such as the Los Angeles Coliseum and New York's Broadway theater district. The new mobile devices in those areas won't have access to channels used by wireless microphones.

Preview of Live Sound Column

Another Green World
Written by John Mayberry
Live Sound International


Who can argue with the current trend of smaller carbon footprints, green packaging, and energy efficiency?

Me.

What a colossal waste of time, effort, and money. “Going Green” is the last thing we should be doing right now.

Something bizarre is going on we’re culturally loathing to admit- a trend driven by guilt, despair, depression, and paranoia. It’s a lemming like rush to the acceptance of mediocrity.

Mediocrity as a virtue?

It’s almost as if the Borg were attacking and we’ve decided to capitulate rather than fight. I don’t believe for a moment that resistance is futile against this mistakenly woeful Green Revolution.

Yet right now we’re stuck in the middle of a conundrum; an unhappy intersection of marketing prowess, Me Generation greed, economic leverage from oversea competitors, and an unhelpful dose of our own stupidity. We must compete our way out of it, not dig our holes even deeper.

I saw my first green audio product the other day. Yeech. Instead of touting its technical merits the press release rambled on about how the packaging was 43% smaller and could more easily recycled. A boring little spit of a product was in the box, but who cares if its carbon footprint is smaller? Are we now playing to the crowd or to the customer?

And why in the world should Americans cut down on packaging? Exporting trash is America’s single largest export! It’s bigger than corn or coal right now- look it up.

In the old days it was the biggest house, fastest car, loudest sound system, or the most sparkling jewel. These days it’s degenerated into something far more sinister. Remember the two buses on the Sex Pistols disc going to Nowhere and Boredom? That’s where the Green crowd wants to take us- and on mass transportation no less.

With apologies to the Renaissance Faire crowd, your world is boring and is not the solution to this malaise. As fascinating as it is to see unshaven Luddites prance about in the dirt with pointed shoes whilst strumming a lyre, let’s just say it’s a fork in the road I’m glad you went down and not me. Yet you have the microphone right now, as they say. And I mean to take it away from you.

The First Lord of Green Boredom in my book is Al Gore, a man who practices something entirely different than what he preaches. His message of apocalyptic environmentalism may have delivered him a Nobel Prize, but if I may I’d like to whisper an opposing message into your ear as well, “Our industry does not sell boring very well. Never has, and never will. We sell excitement, movement, and energy. We sell new and different- spectacular events if it all comes together properly. I doubt the Rolled Stones would have quite the attraction of the Rolling Stones, for instance….”

Do Toyota hybrids sell well in Abu Dhabi? Hell no. Ferraris do. I suppose that’s why they’re building Ferrariland there instead of here. Can you imagine the conniption fits our Greenies would convulse in had they even proposed putting a Ferrariland in Southern California? The best we can hope for a Prius based ride in Legoland.

The Toyota Prius is sold in over 40 countries, yet over sixty percent of their sales have been in the U.S. Ever wonder why? Is it high fuel costs here compared to Europe? Stylish design? High performance (30 HP less than Toyota’s own Yaris)? Low maintenance or insurance costs?

No, it’s because we’re supposed to feel better driving a boring car that’s acceptable to the Green crowd, even if we’re not quite sure where those 600,000 nickel metal hydride batteries are going to get dumped. Perhaps they should try Yucca Mountain- it’s not be used for anything right now anyway. Suffice to say the same crowd that predicts Armageddon from cow flatulence yet gives the battery disposal issues a complete pass.

They even gave the first 85,000 hybrid owners access to the car pool lane in California without any passengers. How that helped unclog the freeways I’m not quite sure. It seems the OPEC boys found a much more efficient technique in my opinion.

The only way out of this mess is with bigger and better technology, not going backwards and accepting lower performance as we pine for the good old days. Our best and brightest engineers should be racing ahead to build the latest and greatest, not wasting their time bragging about the various merits of cardboard packaging and telling us to make do with less performance. They should be building nuclear and fusion reactors, high capacity energy storage, more efficient transportation, and better communication systems.

We got it. Digital consoles, integrated wild tracks, DSP processing, switched power supplies, and line arrays have been very good to this industry. So what’s next, and when do we get it? I want our manufacturers to rigorously go through the entire system concept from start to finish and make the whole thing much better! That is what we need to prosper in the long term. The dreamers, technologists, engineers, and builders that will shape our new reality must be given their chance.

Try an experiment for me. Go up to your head salesperson and tell them you want them to only sell systems that don’t perform well but they are made from eco-friendly low carbon footprint materials. The audience won’t hear anything, but who really cares anyway? I have a pretty good idea where your salesperson’s footprint will be planted on you after that request. It does sound kind of stupid when it hits home, doesn’t it? It’s not different for any other industry.

Going Green may be a very quick way to make your accounting go red and your future black. Paraphrasing Churchill, this may not be the beginning of the end of the Green Revolution. But perhaps it is the end of the beginning. I hope we’re at a point where the platitudes and positioning end and meaningful innovation begins.

Thank goodness for that. Now flip this chlorinated and Kraft pulped (a fascinating industrial process dependent on gas turbine engines, by the way) page on to the next article.

The Top Five Reasons Why Windows Vista Failed

October 6th, 2008
Posted by Jason Hiner @ 4:21 am

On Friday, Microsoft gave computer makers a six-month extension for offering Windows XP on newly-shipped PCs. While this doesn’t impact enterprise IT — because volume licensing agreements will allow IT to keep installing Windows XP for many years to come — the move is another symbolic nail in Vista’s coffin.

The public reputation of Windows Vista is in shambles, as Microsoft itself tacitly acknowledged in its Mojave ad campaign.

IT departments are largely ignoring Vista. In June (18 months after Vista’s launch), Forrester Research reported that just 8.8% of enterprise PCs worldwide were running Vista. Meanwhile, Microsoft appears to have put Windows 7 on an accelerated schedule that could see it released in 2010. That will provide IT departments with all the justification they need to simply skip Vista and wait to eventually standardize on Windows 7 as the next OS for business.

So how did Vista get left holding the bag? Let’s look at the five most important reasons why Vista failed.


5. Apple successfully demonized Vista

Apple’s clever I’m a Mac ads have successfully driven home the perception that Windows Vista is buggy, boring, and difficult to use. After taking two years of merciless pummeling from Apple, Microsoft recently responded with it’s I’m a PC campaign in order to defend the honor of Windows. This will likely restore some mojo to the PC and Windows brands overall, but it’s too late to save Vista’s perception as a dud.


4. Windows XP is too entrenched

In 2001, when Windows XP was released, there were about 600 million computers in use worldwide. Over 80% of them were running Windows but it was split between two code bases: Windows 95/98 (65%) and Windows NT/2000 (26%), according to IDC. One of the big goals of Windows XP was to unite the Windows 9x and Windows NT code bases, and it eventually accomplished that.

In 2008, there are now over 1.1 billion PCs in use worldwide and over 70% of them are running Windows XP. That means almost 800 million computers are running XP, which makes it the most widely installed operating system of all time. That’s a lot of inertia to overcome, especially for IT departments that have consolidated their deployments and applications around Windows XP.

And, believe it or not, Windows XP could actually increase its market share over the next couple years. How? Low-cost netbooks and nettops are going to be flooding the market. While these inexpensive machines are powerful enough to provide a solid Internet experience for most users, they don’t have enough resources to run Windows Vista, so they all run either Windows XP or Linux. Intel expects this market to explode in the years ahead. (For more on netbooks and nettops, see this fact sheet and this presentation — both are PDFs from Intel.)


3. Vista is too slow

For years Microsoft has been criticized by developers and IT professionals for “software bloat” — adding so many changes and features to its programs that the code gets huge and unwieldy. However, this never seemed to have enough of an effect to impact software sales. With Windows Vista, software bloat appears to have finally caught up with Microsoft.

Vista has over 50 million lines of code. XP had 35 million when it was released, and since then it has grown to about 40 million. This software bloat has had the effect of slowing down Windows Vista, especially when it’s running on anything but the latest and fastest hardware. Even then, the latest version of Windows XP soundly outperforms the latest version of Microsoft Vista. No one wants to use a new computer that is slower than their old one.


2. There wasn’t supposed to be a Vista

It’s easy to forget that when Microsoft launched Windows XP it was actually trying to change its OS business model to move away from shrink-wrapped software and convert customers to software subscribers. That’s why it abandoned the naming convention of Windows 95, Windows 98, and Windows 2000, and instead chose Windows XP.

The XP stood for “experience” and was part of Microsoft’s .NET Web services strategy at the time. The master plan was to get users and businesses to pay a yearly subscription fee for the Windows experience — XP would essentially be the on-going product name but would include all software upgrades and updates, as long as you paid for your subscription. Of course, it would disable Windows on your PC if you didn’t pay. That’s why product activation was coupled with Windows XP.

Microsoft released Windows XP and Office XP simultaneously in 2001 and both included product activation and the plan to eventually migrate to subscription products. However, by the end of 2001 Microsoft had already abandoned the subscription concept with Office, and quickly returned to the shrink-wrapped business model and the old product development model with both products.

The idea of doing incremental releases and upgrades of its software — rather than a major shrink-wrapped release every 3-5 years — was a good concept. Microsoft just couldn’t figure out how to make the business model work, but instead of figuring out how to get it right, it took the easy route and went back to an old model that was simply not very well suited to the economic and technical realities of today’s IT world.


1. It broke too much stuff

One of the big reasons that Windows XP caught on was because it had the hardware, software, and driver compatibility of the Windows 9x line plus the stability and industrial strength of the Windows NT line. The compatibility issue was huge. Having a single, highly-compatible Windows platform simplified the computing experience for users, IT departments, and software and hardware vendors.

Microsoft either forgot or disregarded that fact when it released Windows Vista, because, despite a long beta period, a lot of existing software and hardware were not compatible with Vista when it was released in January 2007. Since many important programs and peripherals were unusable in Vista, that made it impossible for a lot of IT departments to adopt it. Many of the incompatibilities were the result of tighter security.

After Windows was targeted by a nasty string of viruses, worms, and malware in the early 2000s, Microsoft embarked on the Trustworthy Computing initiative to make its products more secure. One of the results was Windows XP Service Pack 2 (SP2), which won over IT and paved the way for XP to become the world’s mostly widely deployed OS.

The other big piece of Trustworthy Computing was the even-further-locked-down version of Windows that Microsoft released in Vista. This was definitely the most secure OS that Microsoft had ever released but the price was user-hostile features such as UAC, a far more complicated set of security prompts that accompanied many basic tasks, and a host of software incompatibility issues. In other words, Vista broke a lot of the things that users were used to doing in XP.


Bottom line

There are some who argue that Vista is actually more widely adopted than XP was at this stage after its release, and that it’s highly likely that Vista will eventually replace XP in the enterprise. I don’t agree. With XP, there were clear motivations to migrate: bring Windows 9x machines to a more stable and secure OS and bring Windows NT/2000 machines to an OS with much better hardware and software compatibility. And, you also had the advantage of consolidating all of those machines on a single OS in order to simplify support.

With Vista, there are simply no major incentives for IT to use it over XP. Security isn’t even that big of an issue because XP SP2 (and above) are solid and most IT departments have it locked down quite well. As I wrote in the article Prediction: Microsoft will leapfrog Vista, release Windows 7 early, and change its OS business, Microsoft needs to abandon the strategy of releasing a new OS every 3-5 years and simply stick with a single version of Windows and release updates, patches, and new features on a regular basis. Most IT departments are essentially already on a subscription model with Microsoft so the business strategy is already in place for them.

As far as the subscription model goes for small businesses and consumers, instead of disabling Windows on a user’s PC if they don’t renew their subscription, just don’t allow that machine to get any more updates if they don’t renew. Microsoft could also work with OEMs to sell something like a three-year subscription to Windows with every a new PC. Then users would have the choice of renewing on their own after that.
