Sound, Light and Video – the importance of thinking it through…

We’ve all been there.  It mostly works but it just isn’t good enough.  We’re watching TV or playing a computer game.

So imagine you’re sitting on an aeroplane, you’re watching an in-flight movie.  The quality is really bad.  It gets worse, it becomes so annoying that you have to turn it off.

Now think about that.  What was so annoying about it?

Imagine the video is all wavy and you struggle to make out the picture but the audio is fine.  Now imagine the audio is so bad you can’t hear anything but the picture is fine.  Which one are you more likely to be able to take.

When we watch a video, it’s the audio we need as much as, maybe even more than the video.  We can live with a pixelated image although we might rather it was perfect.  But bad audio will give headaches and cause us to be constantly struggling to hear.

So make sure you use a supplier who understands not just the IT aspects but also the video and audio aspects of the project.  Make sure you use Present Communications ltd.

Corporate clients require only the best equipment…

When it comes to the ultimate in connectivity and flexibility for video conferencing, there really is no substitute for Cisco’s flagship codec, the Cisco C90.

Having spent the last year trying, testing and comparing the C90 to similar products from the same and competitor brands, it has become apparent the Cisco’s product, part of the C-series, released since they bought Tandberg a few years ago has the relaxability in terms of connectivity particularly that the competitors just don’t offer and it’s these features that make is so useful in the live events industry where no two jobs are ever the same.

I can honestly say that we’ve used so many features on the unit that literally aren’t available on other devices, such as DVI input on the main video channel or even just HD-SDI inputs.  Actually clean output busses are handy as well as balanced line level in and out.

So what are we going to do about this.  Well, we just bought two more!

Video Conference service provider or AV company…?

What is the difference between an AV company who do video conferencing and a specialist video conferencing service provider??

Most AV/event production/rental houses will claim to be able to do video conferencing and indeed many of them actually own their own equipment and know mostly how to make them work.  So if I buy a Ferrari, does that make me a Lewis Hamilton?

Setting up a big sound system not only requires a knowledge of power amplifiers, system controller and mixing desks but also requires a good ear if you want it to work well.  Similarly with video conferencing, a good working knowledge of the equipment is necessary but so is a knowledge of IT and networking, phone lines, ISDN, IP, H.323, H.239, H.264, CIF, QCIF, HD, 720P, dual stream, people & content, bandwidth, firewalls, NAT, port forwarding etc etc.  The list unfortunately goes on and on.  Once you’ve got that covered, you then of course have the local connectivity side of things; VGA, HDMI, DVI, SDI, HD-SDI, Composite, Component, S-video. And then there is the audio…

You get the picture.

Present Communications is a specialist video conference provider.  We offer the finest technical support along side our equipment and in many cases offer a ‘brand-free’ service to other production companies and act seamlessly as your video conferencing team.

Firewall problems are a thing of the past – introducing PUNCH!

Firewalls, NAT, port forwarding, words that strike fear into the heart of even the most veteran video conferencing engineer.

There are many ways to set up a codec on a network.  You can allow the codec access to a public IP, NAT to the codec or use simple port forwarding if you think you’re brave enough.

Punch through the firewall

Any of these options require assistance from the in-house IT expert.  Of course that IT person should also be handy with video conferencing and understand the specific port requirements and also how H.323 work.  When you find that person, send him to me, I have a job going.

There are lots of ways that a firewall can be bypassed.  Some are much more complicated than others but mostly they require a lot of configuration.  What is really required by the industry is a way to just PUNCH! through any firewall and present the Video Codec to the outside world on a public IP address outside (and not related) to the network it’s on.
Well, we have this product and if you haven’t guessed already, it’s called PUNCH!  Each device is plugged into any network via the PUNCH! and that device is automatically configured with a public IP address on our network which will work with your Video Codec or any other device.

Don’t believe us, give us a try!
