Six things to think about when purchasing a video wall

Monday, February 29, 2016
Video walls now adorn lobbies, retail stores and public areas around the world, displaying everything from movie trailers to airport schedules. Eye catching and versatile, they are an obvious choice if you are trying to make an immediate impression or provide information in a hurry.  However, there are a few important factors to take into account before investing in this fairly expensive area, broken down below into a handy list.

6: Mounting

 

A strong but versatile mount is the foundation that you will build your display upon, and its not just a matter of choosing the right plate to attach to your screens, but the right surface to mount them on as well. Even though screens are becoming thinner and lighter all the time, once you have 10 or more of them in a grid, it can start getting heavy very quickly.

Another often overlooked feature is accessibility. Plan your mounting system to allow for the fact that you may one day need to easily pull out and replace that screen that’s gone dead right in the middle of the array. Various mount systems allow for this using different methods, from screens that pop out with a light pressure to hidden pull cables.

5: Your audience

 

How big is the area that your screens will be displaying to? How far away will the furthest potential audience member be? Will they be able to read all the text or see the smallest details on your screen? Is the display set up in a way that people can pause to watch without disrupting a flow of foot traffic? These are all factors to take into account when positioning your display.

4: Bezels


Bezels are basically the ‘frame’ of the display screens, and less is more in the case of video walls. Smaller Bezels mean less of an interruption between screens for the images being displayed, especially important if your video wall is being used to display one complete picture across multiple screens.

Bezels can be anywhere between 2 inches to 2.3mm wide, with many variations in-between, but the smaller the bezel, the higher the cost. There are even some new 8k display screens available from LG with no bezel at all, but these are currently extremely expensive.

3: Light


If you’ve decided on a location for your display, take note of how the light may change in that area, throughout the day. Is it ever going to be in full sun? Are there any exterior lights that may interfere with your images? If so, your video wall may be losing a lot of its effectiveness for significant portions of the day.

2: Resolution


A single standard 1080 x 1920 HD screen is fine for displaying a single HD image, but one you start spreading that image out over multiple screens, it may start looking a little pixelated. A 2 x 2 array made up of 1080 screens is actually the equivalent of an 4k display, and would need a 4k source video or feed to display without pixilation.

And a regular pattern of monitors is by no means the only way of displaying. Many different shapes can be incorporated, and they will all need to take source resolution into account to avoid blockiness and distortion.

1: Software



Do you want just one image across multiple screens? Do you want a combination of video and graphics? Will there be the same feeds displaying on individual screens, or do you want them to change throughout the day? Do you want to ‘animate’ your feeds, moving around the video wall?

Different display software will achieve these different results, from simple multi-output video cards that split a singe feed across your screens, to specialized video processors and media players specifically designed to manage large displays. One again, the more features, the higher the price, which is where its important to know exactly what you want to do with your video wall before you install it, to avoid paying for expensive features that you may never use. 

Screen Technology Highlights from CES 2016

Monday, January 18, 2016
The Las Vegas consumer electronics show has recently wrapped up for 2016, with many exciting new technologies featured. Following recent trends, screen resolutions and sizes have increased, while diameters have decreased.

Many of these new technologies may be a few months away from becoming available in New Zealand, but the show offers a unique opportunity to glimpse what may be available for audio visual display and promotions in the near future.

I’ll see your 4K and raise you 8K



4K Televisions have barely hit the NZ market, but the Las Vegas show featured a few companies showcasing 8K display technology. 8K is basically 16 times the resolution of 1080p, and does beg the question of how big a market is available for such a massive jump in resolution, given that the number of movies available for 4K tv’s still only measures in the low hundreds.

As with many of these super high res displays, much of the interest is from the Asian region, specifically Korea and Japan. Ever forward thinking, Japan has a long term plan to broadcast the 2020 Tokyo Olympics in 8K, when presumably screens will have dropped from their current price of around US$133k for an LG 85 inch screen. Its hard to say whether screens of this sharpness will ever become widely used, but for the foreseeable future, its fairly certain they will just remain an expensive novelty.

Bigger, and bigger still



Another star of the show was this years claimant for the coveted ‘biggest tv’ spot, taken by Samsung’s massive 170 inch screen. The term ‘screen’ being a little misleading as the display is actually modular, being made up of a number of smaller screens acting in unison. However, new technology which has enabled Samsung to eliminate the bezels or borders on their screens makes this massive, multi screen display appear like one huge unit to all but the closes inspection.

This unit was more of a showcase than anything that will every become publicly available, but it certainly shows off the possibilities available with the slimmer border-less screens for all video wall design types.

One screen - Two feeds



With the advent of OLED displays, not only has it become possible to make TV’s thinner and curved, LG has come up with a way to display two different feeds on each side of the panel. Currently only in prototype stage, this particular technology probably has more applications in display and promotion rather than home use. One can imagine the 5mm thin sheets hanging from the ceiling or installed in a transparent wall, allowing customers to walk 360 degrees around and take in all the content.

Dr Ching W Tang, one of the pioneers of OLED technology believes that this new way of displaying images will become commonplace in the future, stating that "Without backlight and other auxiliary layers, the OLED display is fundamentally less complicated compared to LCD, and in time less costly to manufacture." Given the variety of applications and formats already being toyed with while the technology is still in its infancy, its not hard to see how OLED screens could soon become the norm, both for business and consumer use.

Outrageously thin TV - The width of 4 stacked credit cards



With the new OLED technology, screens have been shrunk down to thicknesses previously thought unimaginable, including the new LG G6 with measures a stunning .11 inches thick…something LG’s senior marketing leader David Vanderwaal describes as “a picture on glass.”

Not content with resting an their laurels by inventing the worlds thinnest screen, LG have also programmed it with intelligent ‘HDR pro’ technology. This allows the screen to adjust the brightness and darkness of its image to match the brightness of the surrounding area, allowing the display to act more like a window onto another reality rather than just a TV screen.

An LED Screen that rolls up like paper



And finally, LG also introduced something that has been talked about for a while but is only now becoming reality…HD TV screens that can be rolled up like a newspaper.

The new organic light emitting diodes (OLED) that make up the image on screen produce their own light, eliminating the need for the back lights that made up the bulk of earlier displays. The 18inch panel showcased is roughly 4mm thick, and nearly indestructible. By placing a thin magnetic strip on the wall surface of your choice, the screen can be placed and removed at your convenience.

Exciting as this is, there are a few downsides. Firstly, the screen can currently only display at a resolution of 1200 x 810. Secondly, the price could be prohibitive, considering that the closest commercially available OLED unit retails for around US$9000, even without the novelty of it being paper thin and flexible. The final, and probably most important downside to this new technology is that LG hasn’t quite figured out how to mass produce them yet. According to AJC.com, they have hit an 80% yield, which means that 20 percent of their screens just don’t work. So, it may be a few years yet until you can live your dream of a roll away TV, but the interest in this technology indicates that we may see it commercially available sooner rather than later. 

NZI Building - 7 Sources x 5 Displays

Sunday, July 26, 2015

For two years various displays in the NZI building sat idle and unused due to an end of line AMX Endeleo TV over IP distribution system which was no longer up to the task of modern signal distribution. IAG Collaboration Specialist Richard Everitt, tasked with replacing the retired Endeleo system, enlisted the design services of Paul Monaghan from ProVision Technologies to come up with a new solution to distribute high definition video, audio and control throughout the ground floor of the NZI building to various meeting rooms, huddle spaces, staff rooms and foyers. 

 

The new system was required to work over the existing Cat5 structured cabling installed throughout the building and with the existing displays and sources. With the scary thought of having to install a system on unknown cabling Paul's first thought was Just Add Power. Since Cat5 cabling can easily support a gigabit IP signal the HDMI over IP signal the HDMI over IP signal distribution allows for realible links up to 100m where HDBaseT would typically not be possible.

 

For the task at hand a 7x5 HDMI matrix was designed and installed by the team at ProVision Technologies. This consists of seven Just Add Power 2G+ transmitters and Cisco 28 Port managed gigabit switch, all centrally located in a 19” rack. Five 2G+ receivers are spread throughout the building at the existing display locations with their low profile allowing them to remain inconspicuous. Display control is achieved by RS-232 injection over IP through the Just Add Power receivers, all easily programmed with the help of the drop in drivers for AMX. 

Because of the scalability of the Just Add Power solution, Richard knew he would be able to grow the system as and when required and plans are already underway to expand this throughout more of the building. Richard is extremely pleased with the Just Add Power solution provided by ProVision Technologies based on its excellent value for money, flexibility, scalability and most importantly reliability.

Transparent LCD Screens    

Every so often, a reincarnation of an existing technology comes along to remind us that we’re living in the future. Something that has generally only ever been seen in science fiction, or created by a special effects artist.

A recent example of this might be the telephone, which has graduated form clunky rotary dial house phones, to ‘brick’ mobile phones, to handheld models and then touchscreen smart phones. The television has also come a long way, from a black and white tiny box, to massive flat screen HD panels.

However, even these great advances are now considered ordinary.  Nowadays, it takes something truly revolutionary to capture the attention of the masses, and that revolutionary invention may very well be a transparent LCD television.

 

Imagine looking inside your fridge without having to open the door, and the transparent fridge door suggesting recipes depending on the combinations of foodstuff inside. Imagine a display cabinet that automatically update the description and prices of the objects placed inside it. Imagine a TV you can roll up and take anywhere.

The technology behind transparent screens has actually been in development for quite a few years, but has only recently begun to hit the mainstream. There are two main types of display in the market today:

OLED
This is currently the most common form of transparent display on the market. It works by using two panels of glass to sandwich the OLED screen itself, which produces the image. The main difference between this and an LCD screen is that the OLED generates its own light, allowing the screen to be much thinner, and work well in darker environments. However, this technology has been prohibitively expensive in the past, although costs are dropping as more advances are made.

LCD Display
An LCD screen is usually unable to be transparent, due to the fact that they need a solid base to produce a backlight, which also tends to make them thicker and heavier. Some recent LCD screens, such as the LG smart window have gotten around this issue by utilizing available light as a backlight, resulting in a 90% reduction in energy costs to display the image. However, they do have restrictions on their use due to the reliance on available light.

In either form, transparent screens are poised to take the advertising and retail worlds in particular by storm, given the myriad of applications that the technology has in the field. Instead of a static display, or TV screen advertising that blocks everything behind it, retailers now have the option of placing their wares behind a transparent display that allows customers to view their product while reading dynamically updating information about it. Or even interactive display cases, enclosing a product while potential buyers can swipe through information displaying on the surface.  Another early adopter of this kind of technology is a company called Planar who have created what they call the ‘Lookthru’ box.

This is basically a display case that can deliver a variety of information on its surface, including images and video, while still allowing customers to see the product inside. It can be used in portrait or landscape mode, and is useful not only for consumer products but also as a display case for museum artifacts, trophies, tradeshow exhibits and more.

Another application that’s in development? Cafeteria displays and vending machines, which can be updated depending on the products inside, and would allow you to place orders and read customer feedback, or even input their own.

How many of these new innovations actually catch on to become features of regular life remains to be seen,  chances are at some point in the near future, you’ll not only be looking at your TV but looking through it.

Saving the best for last, here's the best example of this pretty cool technology.

Google Glass

Tuesday, September 09, 2014

 

Any new technology is going to be treated with suspicion by a large portion of the population, due to lack of understanding and misinformation. It happened during the birth of the Internet, and now it’s happening with another new and strange technology, Google Glass.  

Google Glass is a reality augmentation device, in essence a wearable computer. It has been available publicly for little over a year, in an extended trial period where the units have been made available to what Google colourfully called its ‘Glass Explorers’. However, in the short time that the technology has been available, the users have been given a new and less flattering moniker by unwelcoming members of the public – Glassholes.

Before we get onto the reasons for this, lets take a closer look at what Google Glass does: Google Glass is a tiny computer projecting onto a clear screen over one eye. It’s operation is similar to that of a smartphone, with users able to access features via a touchpad on the side of the head.  It is, however, designed to be largely hands free, with apps navigated by voice commands, tilts of the head and even blinking.

Using Google Glass, you can view a map without taking your eyes off the road,  send a text message just by speaking, take photos and record video. And it is these last two features that have made the hardware and its users an object of suspicion to many. 

In early 2014, a Berlin based programmer named Julian Oliver released a small piece of software called glasshole.sh, which has one simple function. It can detect the presence of any Google Glass user on a local Wi-Fi network and boot them off. Since it’s release, the software has proven popular with restaurants, nightclubs and bars, as well as these signs available for free download from anti glass website stopthecyborgs.com

 

Why the backlash? Put simply, privacy fears. When someone takes a photo or records a video with a camera, or even a smartphone, their actions and intentions are generally clear and difficult to conceal. With Google Glass, however, the perception is that a user can be recording, taking photos and uploading to the internet, all while looking as though they’re reading a paper or drinking a coffee. What happens when people see someone wearing a device they think could be recording them at any time?  Suspicion, abuse and physical attacks. People have had their units ripped off their faces and smashed on the ground. Growing numbers of social establishments in the USA have banned the devices outright. They’ve even been called a ‘Social Divide on your Face’. Ironically, you only need to do a simple Google search on ‘Google Glass backlash’ to see how widespread the suspicion towards this new device is. But does it deserve such a stigma?

When film cameras were made available to the wider public in the late 19th century, outraged people declared an end to privacy. Cameras were banned in parks and beaches. The same privacy fears emerged when the first cell phone cameras were released. Could we just be seeing a resurgence of this trend?  Even Google executive Ed Sanders calls the backlash a ‘necessary symptom of a company that’s trying to be disruptive’.

Also, many of the beliefs about Glass are merely misconceptions. It can only record 10 seconds of video at a time, and needs a spoken command to begin, or a fairly obvious ‘wink’ to take a photo. Future versions of Glass may include a blinking light or similar when recording to allay privacy fears.

Aside from these concerns, one of the biggest questions about Google Glass is whether it will be a successful product, given that it hasn’t even been made commercially available yet. A year on from their initial enthusiastic purchase, some early adopters have complained of finding their units slow, limiting and unwieldy, however it could be argued that discovering these faults is the whole point of a public trial before a wider release.

Only time will tell as to whether these units become a new and viable alternative to smartphones, or a fascinating and controversial experiment in technology and human nature.

The Rebirth of Virtual Reality

Saturday, August 02, 2014
If there’s one visual technology that has struggled to live up to it’s potential more than 3D , it would be virtual reality (VR).  It is a concept that has been around for a surprisingly long time,  being the subject of a short sci-fi story written in 1930 called ‘Pygmalion’s Spectacles’, which describes a goggle based VR system, which includes the senses of smell and touch.

It is possibly this unrealistic expectation of VR, that it will instantly and seamlessly transport us into another world, that has hindered its mainstream acceptance.  This has not been helped by the portrayals of VR in mainstream media, such as the ‘Holodeck’ in Star Trek: The next generation, or even the Matrix itself in the Matrix trilogy. In reality, VR users have always been very aware that they are wearing a headset and looking at a tiny screen inches from their face.  But the next generation of VR technology aims to change all of that.

The hardware creating the biggest buzz most recently is the headset called Oculus Rift.  Although not currently in stores, the second version of it’s development kit (DK2) is available to game developers, and includes a host of features that set it apart from older generation headsets.

 

•    Positional tracking. With this, the Rift can track the position of your head in realtime, meaning that virtual environments can be interacted with in a host of new ways not possible before. You can now peek around the edge of a wall, lean forward to get a closer look at something, lean back to avoid danger…all of this makes the VR experience more intuitive and immersive

•    Low persistence: When you turn your head in the real world, your vision doesn’t tend to blur, something that has been a persistent issue in VR displays. With a combination of higher frame rates and a new OLED HD display, the Rift aims to reduce or even eliminate this blur, and the motion sickness that it can cause.

 

•    Latency. This describes the delay between movement from the user and the action on the screen (called motion to photon latency). Latency is a massive issue in VR, as a delay of even fractions of a second can cause disconnect from the experience, and even the dreaded motion sickness mentioned before. As more and more complicated games are developed for the Rift in full HD, maintaining near zero latency will remain an ongoing challenge.

The parent company of the Rift, Occulus VR has recently been purchased by Facebook for $2 billion US, so this is obviously a technology that some people are taking very seriously, and with that interest comes competition. There are already a number of other headsets out there vying for a slice of the VR pie, with technologies ranging from tiny projectors that shoot a virtual image directly onto your retina (the Avegant Glyph) or a lower end version that acts basically as a frame for using your own smartphone as a VR display (the Durovis Dive).
All of this technology is primarily geared towards playing games and watching movies, but VR can do much more than that. The first recorded commercial usage of the Rift was a small startup company in Prague offering people the opportunity to take a virtual helicopter tour of the city by sitting on a hydraulic platform and viewing a 3D Prague through the headset.

VR training has been around for as long as the flight simulator, but these next generation headsets are already being adopted as training devices around the world, in both military and civilian applications.

With the use of omnidirectional treadmills, users can walk or run freely though entire virtual landscapes, opening up a market for VR ‘gyms’.  One Swiss team has even combined a headset with a hydraulic rig, allowing a user to fly like a bird.



Other, more esoteric applications include mental therapy and physical rehabilitation. Some amputation patients have been found to reduce or even remove phantom pain by wearing a VR headset and controlling a virtual arm.

After something of a false start in the early 90’s, VR seems poised to make a massive comeback in the commercial and home use markets. How it will be used seems to be limited only by the developers imaginations.

4K – how many pixels is too many?

Monday, June 23, 2014
Our viewing standards have changed massively in a very short time. In little over a decade, we have moved from boxy 4:3 SD (Standard Definition) images on our TV screens, video cameras and computers to 16:9 widescreen becoming the norm. Full 1080 HD is now commonplace, where it was seen as revolutionary just a few years ago.

SD DVD’s have been replaced by HD bluerays, which in turn are threatened by Video on Demand (VOD), streamable media and 3D TV. It seems that new standards are emerging at an exponential rate, and it may seem difficult to keep up. However, progress waits for no man, and already there’s a new video standard looming on the commercial horizon that aims to make the still recent HD obsolete, and that standard is 4K.

On the face of it, 4K isn’t new, and has actually been around for a while, but really only in the broadcast and commercial entertainment industry. The first 4K camera, the Dalsa Origin was available way back in 2003, and Youtube has been offering 4K resolution videos for viewing since 2010. Cinemas have been projecting their films in 4k for a while now, and Sony released the first 4k home theater projector in 2012.

How much difference is there between 1080 HD and 4K? A massive amount, as the image below shows.

1080 HD comes in at a resolution of 1920 x 1080 pixels, as opposed to 4K which has two resolutions that will target the consumer market – UHD, at 3840 x 2160 or UHD-2, which comes in at a massive 7680 x 4320 pixels.

 


Obviously, the main challenge posed by broadcasting, encoding and storing such enormous resolutions is the sheer amount of bandwidth and storage space required to deal with it. Even a compressed one hour video file would be over 160GB in 4K. However, these challenges are being met by the manufacturers of the first wave of 4K televisions, which include Sony and Samsung.

At this point there are no plans by any major broadcasters to air in 4K, the bandwidth requirements are simply too large. However, early adopters of the new Televisions will be able to choose from a large range of big budget feature films, many of which were shot in 4K and also older films which were shot on 35mm film and can be up-scaled.

The question asked by many is how much is this massive upscale in resolution actually needed? There is some skepticism that the benefits of this standard will ever outweigh the challenges and increased cost, especially when the following points are considered.


Click for a larger image to compare the quality

  • Viewing Distances – In the bad old days of 12 inch screens and SD images, people sat at an average distance of 3 meters away to view. Despite massive changes in screen sizes and resolution, people in general still sit the same distance away when they watch TV. At this distance, the resolution benefits of 4K become negligible.
  • Screen sizes – Unless of course you have a screen sized between 80-100 inches or above. According to studies though, screen sizes in the average household still sit somewhere between the 35-40 inch range. Unless prices drop dramatically, it’s hard to see this changing.

Taking this into account, will 4K ever become a mainstream standard like 1080 HD has? Streaming broadcaster Netflix believes so, and has made one of their flagship shows ‘Game of Cards’ available for streaming in 4K for the lucky (And wealthy) early adopters. However, they believe that the industry is still five years away from the ‘critical mass’ needed, where prices have dropped sufficiently and there’s enough content available for the general population to enter the market. At this point, 4K televisions will become the norm on store shelves, and 1080 will theoretically go the way of SD.

As always, it’s impossible to predict exactly which way any new technology will develop, and it’s entirely possible that some new standard will emerge in the next few years that will render any debate about 4K obsolete. At this early stage though, it’s definitely a technology to keep a close eye on, even if it means moving your couch a little closer to the TV to get the full benefit.

3D Technology - Here to stay?

Wednesday, June 23, 2010
The technology that seems to be on everyone's lips these days is 3D. Retailers are pushing it, moviemakers are designing movies especially for it and, at the moment anyway, the public seems to be lapping it up. But is 3D here to stay, or is it just experiencing a resurgence in popularity, similar to previous 3D movie crazes in the 50's and 80's, and may eventually sink back into obscurity? Could that 3D TV you just purchased become an expensive white elephant in a few years? What does the technology mean for other industries, including video conferencing?

As an art form, 3D seems to have an equal share of supporters and detractors. One of the most famous early embracers of 3D movie making of course is James Cameron, with his blockbuster film 'Avatar'. He argues that 3D cinema is providing a resurgence in movie going, the viewing audience actually visiting the cinema for the experience of seeing a 3D film that is, for the moment anyway, largely unavailable at home.



He also speaks of other applications, beyond movie making, saying  that “Once you can use this installed base of 3D theaters to allow people to participate in world events that are happening thousands of miles away in 3D just like you were actually there, think of the immediacy. Think of the power of that"

Possibly the most high profile detractor of 3D cinema so far is film critic Roger Ebert, who see's it as nothing more than a gimmick, adding little and possibly even detracting from the immersive experience of movie going. In his article 'D minus for 3D' he ask's the question “Have you ever watched a 2-D movie and wished it were in 3-D? Remember that boulder rolling behind Indiana Jones in "Raiders of the Lost Ark?" Better in 3-D? No, it would have been worse. Would have been a tragedy. The 3-D process is like a zombie, a vampire, or a 17-year cicada: seemingly dead, but crawling out alive after a lapse of years. We need a wooden stake"

It's important to note at this point that there are two main methods for creating a 3D production. The first is by shooting the film with 3D cameras, designing the shots and constructing the film specifically with 3D in mind, as James Cameron did with 'Avatar'. The second is to take a film that has been shot in 2D and digitally 'Dimensionalise' it. The first way is superior, but far more expensive, but the second way, although cheaper, can lead to substandard 3D, as with the largely panned 'Clash of the Titans'. It is presumed that this movie was never designed to be in 3D, and a rush job was done on the back of the success of 'Avatar', so it's maybe a little unfair to judge. A better test of how good 'dimensionalising' a movie can be will be with the 3D re-release of the upcoming 'Star Wars' trilogy.

Many will say that the current 3D fad is little more than that: a fad. In the words of film historian Daniel Symmes 3D is 'The Circus coming to town. Does the circus stay around? No. If it does, attendance drops off, the novelty is gone and the circus goes away." However, there is one very large difference between the 3D of today and cardboard Green and Red lenses of yesteryear, and that is the digital revolution, which makes for faster, cheaper and more precise 3D and more importantly brings it into the home, converting movies and TV shows that weren't even shot in 3D. It's still too early to say, but early indicators are that the technology may be here for the long haul, especially with some industry people suggesting that 3D screens that eliminate the need for glasses may be as little as three years away.



What does this mean for other applications such as video conferencing? Well, replace the current generation of video conferencing cameras with a 3D camera and combine it with a large enough 3D screen, and the concept of the global boardroom becomes even more immersive and seamless. There is also a technology in development called HeadSPIN, that scans and projects a subjects face onto a 3D model in real time.

Combined with a special projection screen made from a concave spinning mirror, this allows the appearance of the face to change depending on the viewing angle of the audience. This, and similar technologies allow the participants in the conference to attain true eye contact during speech, something impossible with 2D video conferencing. The implications of this shouldn't be underestimated. For example, using traditional video conferencing media one speaker talking to a boardroom of people may be talking to one particular person in the room,  but to the members of the room he would appear to be looking directly at each and every one of them. This is because he is actually just looking into a camera and his image is being projected onto a 2D screen.  With HeadSPIN and other new methods of communication in development, this limitation is being removed, making for very natural interactions. The ultimate goal is to make the interface as transparent as possible, so much so that people communicating between boardrooms in New Zealand and London may even forget that there is an interface there at all.



Widespread adoption of this kind of video conferencing may be a few years away yet, but early prototypes of this kind of setup are already in advanced development by companies such as http://www.musion.co.uk , who's 3D projection technology has been used by Bill Gates and Prince Charles to 'Virtually' attend conferences and presentations.

In this sense it seems that even if 3D doesn't survive in the cinema (Until its next incarnation anyway) the new digital technologies that are being used to produce it may have it finding a new and long term home in video conferencing.
