Video Servers

May 12th, 2012

air_smallOur Matco servers have been acting up lately. Our original one is several years old and acts up now and then. A client of ours got a Matco more recently but has stopped using it so we switched over to that one but that too has been going or driving us nuts. When to clips are back to  back the second one does not play for some reason. the server just stops and we switch to the default input on the switcher.

We are planning to have one or the other serviced by Matco but the decision was made for us by PG&E, when we lost power (see next post or two) it killed the power supply on our Matco. So it’s down.

single-channel_smallBut a friend of mine has been looking at a newer server company called Cinegy, a newer automation / video server software package. I saw them at NAB 2012 and they seems very friendly and helpful. They offer a free demo, it comes with no limitations, just a key over the output channel. This way you can really get to know the product before laying down your bucks.

My friend has been looking at the product and likes it, which makes me think it could work for us. It can do several output channels at once and you can get a CG program for it but thats a bit pricey for us.

Maybe even use the old Matco box to run this in, but I think I  would prefer a new box with lots of storage.

We could sell all our old equipment and just have a couple of these with a network to ship files around the studio. I think this could work out really well.

New Radios

April 24th, 2012

Working on a project that uses IP radios to transmit HD-SDI over IP. These radios are from Exalt and can work at upto 1Gb/s. The great thing is that we can monitor and control both ends via a Web GUI. I was sitting up in the office looking at the data rate and received signal levels of both the local and remote transceivers.  We have some alignment to do on the dishes as the received levels are too low, I think we may be on a lobe and not the main beam. Plan to fix that tomorrow.

The Fifth Day at NAB 2012

April 19th, 2012

First it was a Broadcasters Breakfast with ERI, they laid out a really nice setting and then got down to business. They had the story of  KJAV and the new Chief who found the tower about ready to fall. ERI worked with the station to take down the old one and put up a new one in just a few weeks. They showed video of how different tower are taken down with controlled falls and how they  make sure the TX building is not damaged. Very interesting.

Then I went by their booth and asked if they would help with a video I am thinking of on guyed towers. They were very cooperative and I hope to use ERI to make sure I don’t make any mistakes in the tutorial.

Later in the day a seminar about Cel Phone ENG. I know they have been doing this for at least a year or two now but it has really grown now. They talked of a news piece covered by ABC with both a Truck and a Cell Pack and when it started sooner than expected the Truck was not ready and it was covered with just a Cel Pack. Other events have been covered on moving trains even.

The 3G networks can be hard to get thru as more and more smart phones are used and latency is a problem, thats why multiple cel phone network adapters are used (lots of Rabbit Ears as I call them). But even with 4G it will fill up too. Even with great compression it’s still a lot of data to move over something designed to get you your Google map or update your phone Apps. They see a combination of Cel Networks and WiFi as an answer when the system can use both at the same time to off load some of the data. Panasonic is even working on a ENG camera with LTE networking built right in.

One company, TVU, is working on a backpack with both Cel Network connectivity and ASI out to feed a remote truck so both can be used as needed.

Stopped by the FEMA booth and they had a little model of a Primary Entry Point facility. Very interesting and something I will go into more detail later on.

I met Steve Mareen of RF Specialties Group over at the Hitachi / Linear booth where I met the guy who is going to setup one of their exciters at my transmitter next week. They want to show it off working on a real high powered transmitter and I agreed to let them do in. They tell me it should take all of 1/2 hour to get it going. I will report on this next week.

Before that I was over at the Thomson booth and talked with Michael Roosa our salesman and Richarad Fiore Director of Transmission & Mobility about their new exciter the ATSC 8000 which I was told the story of a station that wanted to increase it’s power level from 40KW to 50KW as I recall but pushing the tube that much made correction so difficult that after several exciters were tried only the ATSC 8000 had the correction range to get the job done.

I walked over to TeraDek and saw how small they make the SDI to Cel Network adapters now little bigger than a paperback book. They also make one that uses WiFi to stream to a local laptop or to iPads for remote monitoring. Pretty cool.

 

Time to get out to the show for an early start on the last day and then it’s back home.

Day Two at NAB 2012

April 15th, 2012

Today started off with Final Cut Pro X, I have been thinking about it since it was announced last year at NAB but have not done anything with it. I have not heard the best things about X but with todays session I have a very good feeling for it.

It’s redesign seems to be about metadata, FCP X is all about metadata. It works with ProRez 422 and will auto transcode to it from almost any other codex. I liked it.

Next it was Harris trying to convince Radio engineers that they should use liquid cooling instead of air. Water is able to cool much more than air and it seems Steam can cool 20 times the amount of water. My old RCA TTU UHF transmitter used steam cooling. In air cooled transmitter you can’t hear yourself think with all the A/C.

Then I listened to Charles Kiefer who talked about “Just Start: Take Action”. It was all about taking your idea, your passion and moving forward with it, don’t plan it to death but take small steps, using what you have on hand and asking for help. And Just Start.

Sound Design, using sounds to make better Bumpers and Zingers in videos. The big points where to not depend on just canned sounds from libraries. Either make your own sounds through recording live sounds and then alter them or just add to library sounds by altering them in multiple ways.  We watched several bumpers and anlyzed the sounds used.

The last session of the day for me was about making better training videos. This was a great session tougt my Douglas Spotted Eagle, he knows his stuff. I took a lot of notes and really hope to improve my future videos form attending.

So after two days of session I have learned a great deal and starting tomorrow there’ll be more sessions and products to see on the floor.

First Day at NAB 2012

April 14th, 2012

Worlds Smallest HD Production Vehicle at NAB 2012

It was tough getting into the hotel at around midnight, and then getting up to go to the 8AM Ennes Workshop. I almost fell asleep a couple of times but that was not the presenters fault.

First we had a little lesson on IP, including the difference between v4 and v6. They covered why IP is important to Broadcasters and how their jobs and IT’s jobs overlap.

Then it was onto the Cloud – and how broadcasters can achieve a level of savings from moving as many operations as possible to the Cloud. The Avid guy was a real beleiver in the Cloud and how you can use it for Software as a Service (SaS), to use as an infrastructure  and another one I can’t remember right now, must take more pix.

Here’s information  on Cloud computing

They also talked about Scaleability, the power to adjust the size of your IT along with your needs. Since you don’t own it you pay for just what your use, like your gas and electric bill.

Food for thought.

We also hear from Jerry Whitaker about, of all things, tube audio amps. He really likes the sound of them over our new fangled solid state ones and seems to be building his own these days. I noticed that all the pictures were of Tube Amps with his name on them. But he did make good points.

Someone noted that this was the first time in thirty years that Tube Amps and vinyl records had been discussed at NAB. And someone else noted it was the first time they had seen a Tube schematic on a Power Point presentation.

Mac Attack

April 12th, 2012

Did you hear about the latest attack on the Mac OS?  It’s called Flashback Trojan. When I hear about it I checked to be sure I was clean (I was). But if what you do on your Mac is import an then you need to be serious about protecting it.

Here is a slide show with 10 recommendations on how to keep your Mac safe, from eWeek.

Wrong Fiber

April 11th, 2012

Multi Mode 62.5/125

We order some Fiber Optic patch cables the other day and when they arrived and I opened the box I was greeted by a sea of Orange.

What we ordered was Dual SC on one end and Dual LC on the other, on Single Mode fiber. Single Mode fiber is usually, alway Yellow, and Multi Mode fiber is usually, always Orange. Then on top of that the Orange patch cords have printed on them 62.5/125. This is referring to the 62.5 nm (nano meter) fiber strand inside and the 125 nm outer jacket, which makes it too big to be Single Mode.

Right on the packing slip is states these are non returnable (custom made) and I think, “did I order the wrong cables?” But then I look a little further down and it states, ‘single mode’.

Single Mode 8.3/125

I e-mailed to the manufacture and they told me their assembler did not read the order correctly and they will be sending us new, single mode cables.

IP Radio

April 11th, 2012

We’re putting in some IP radio links that will transport HD video back to the stations. Today we were getting one of the radio links up and running. It works at 11 GHz. The radio is attached to the back of a 6 ft dish and uses only CAT5 cable to connect to it. The one cable carries power and data.

First a Surge Suppressor is placed in-line followed by the POE (Power Over Ethernet) adapter and then it’s connected to the Network switch. We have a fiber optic network setup so the switch has a F/O SFP that takes the data downstairs and on to where it’s going.

We’ve come a long way to be able to hook up a microwave with a Cat 5.

Wired Network for iPad

March 26th, 2012

We are looking at using an iPad to display data while on the tower, to do this we would need a wired network connection since a wireless network won’t  (may not ) work. But I cannot find any adapters to allow a wired network connection for the iPad. It seems that the common solution is to use a pocket wireless router that plugs into the RJ45 and provides a wireless network for you. The iPad to USB adapter will not work with a USB to Ethernet adapter as I have read, so thats out.

The reason for this is FileMaker Go, it’s an App that lets us access a FileMaker Pro file on your iPad or iPhone. I created a data base in File Maker to keep track of all the antenna and cables on the tower, it uses seven data bases to contain all the data. If the iPad is on the same network as a computer with the data base on it can be accessed on the iPad. If not, you can load the the files on to the iPad or iPhone and then you can load the changes back to the computer based data base.

The reason for all this is so I can go put the tower and compare the data base with whats really up there.
