Re: NBC Namedropper Trigger Configuration Help

One of these days, I'm hoping NBC will start IP-streaming the backup feeds. The new RIST (ARQ) protocol makes for a surprisingly robust link, even over public internet circuits, and you don't need the overhead of forward error correction. Having a feed that doesn't suffer from sun outages, rain fade...

Re: Adding Genlock

If you remember also, the original Teranex upconverters wouldn't encode captioning. You'd have to use an external captioning encoder. On our first generation Harmonic encoders, we had a serial feed from the Evertz captioning encoder into the Harmonic to send CC. (Long before the 708 standard became...

Re: Adding Genlock

Yikes that's a hefty price tag.. I don't know their history but am interested now. They were pricey indeed. It reminds me of when scientific pocket calculators first came out: the original HP35 sold for $395, and the programmable HP65 was $795 (equivalent to about $6,500 today). The HP35s on my des...

Re: NBC Namedropper Trigger Configuration Help

Glad you were able to figure it out. How do you not have a Skypath rack? You must be a new affiliate. Most of us are lucky enough to have 30-year-old dishes with a rack of 1290 receivers protected by a UPS that takes a month or more for NBC's contractor to ship a replacement when they die. :D Our c...

Re: NBC Namedropper Trigger Configuration Help

As a starting point, I would patch the Namedropper out of the air path and connect it straight to the RX8200 output, and see if it triggers. If it does, then hook Namedropper to various points in your chain to see where it stops triggering. Our plant happens to be a centralcasting hub that includes ...

Re: Adding Genlock

I have to chuckle when I see newer Teranex units selling for around $1500: our original six cost something like $60,000 apiece, and were not nearly as versatile. They also consumed a great deal of power for their size -- at least 500 watts apiece, with the result that we had to install the same sort...

Re: Cheap Chyron

I should backtrack... are they analog, or standard def digital, or what? If they're that old, maybe a better solution is to seek out a piece of used equipment.

Re: Cheap Chyron

You're looking for graphics generation, not captioning, right? If they are using a newer Ross production switcher (e.g., a Carbonite), a relatively inexpensive solution is the least expensive version of XPression. It runs on a standard PC, and pushes rendered graphics into switcher frame buffers so ...

Re: Smpte timecode to ESE timecode

I rounded up a really long bnc cable from my garage to run down the hall and test the leitch timecode. Does anyone know off hand will the timecode connectors be 50 ohm or 75ohm (hopefully)? We use 75 ohm connectors simply because that's what we have; unlike N connectors which have smaller center pi...

Re: Smpte timecode to ESE timecode

Or am I dumb and the evertz can generate ESE timecode? it's a big manual I suppose I could have missed it... Nope. Valid Question. ESE TC is proprietary to them, and for the most part they only sell SMPTE equipment now. Anyways, you're going to want an ESE ES-462U, which takes ESE TC and converts i...

Re: Smpte timecode to ESE timecode

Funny you should post this: we just replaced an ESE 185 master clock with an Evertz 5601-MSC system, and had this exact issue. The Evertz produces several different flavors of timecode that mostly seem to affect how the date is presented: "Legacy Date", which is compatible with older Leitch master c...

Re: Adding Genlock

We have something like four dozen OpenGear frames in our shop, ranging from the oldest black frames to the newest frames with front LEDs that let you change the color. They have been a workhorse, and typically have little mechanical trouble (unlike our Evertz 7800s, which seem to have issues with re...

Re: Sync, time code, and insanity

As an aside, thinking about that Tektronix R146 is a powerful reminder of how profoundly broadcast equipment has changed: most of the signals it produces have not been relevant in at least 25 years, but our Ampex VTRs and GE cameras depended on them: Subcarrier (continuous 3.57MHz sine wave) Composi...

Re: Sync, time code, and insanity

We are a regional hub, so our automation controls twelve feeds in addition to another twelve feeds that are passthrough with minimal local insertion (e.g., Bounce, Laff). So yes, all twelve main program feeds came to a grinding halt. What we have since discovered is that the automation can free-run....

Re: Adding Genlock

It comes down to where you're comfortable in terms of the risk/cost balance. I'd never dream of using loopthroughs to feed our network signal to our master control switcher. On the other hand, if I were at a high school building a control room to record baseball games for broadcast on Facebook Live...
