Re: Video feed problem

I'm replying to your PM back in the forum thread, because then other people who visit with similar questions can see the answer too. From what I understand, your question really boils down to understanding what the different components actually do, and how they fit into a complete production / broad...

Re: Video feed problem

Can you give a bit more detail about what you're trying to do? It sounds like you are wanting to feed video into a projector... so it would be a matter of getting appropriate interconnection from the switcher into the projector. Knowing specifically about the switcher and projector would be helpful ...

Re: Need help with Sony BVH2500P

It's my pleasure! I think most of us around here get a real kick out of helping people keep vintage equipment going, and it's nice when practical experience comes in handy.

Re: Need help with Sony BVH2500P

My first guess is that the problem is not really with the motor driver or motor, but rather with the servo system -- in particular, the supply tension sensor. Here's a quick way to eliminate the motor and driver: 1) Mount a full reel of tape on the supply hub, and make sure the end of the tape is se...

Re: KVM Suggestions

Darn -- Raritan was going to be my first suggestion; we have four Dominion series units of various ages and sizes, up to a fairly new 64x4 unit. You might take a look at Avocent -- I haven't used it, but have heard good feedback about their stuff. Their Matrix series is supposedly scalable, so you s...

Re: Animated Graphics with Transparency and ATEM Switchers

What you're doing is actually a luminance key, and the key clip level adjustment is the center of the threshold for enabling the fill video. The key gain adjustment lets you set the threshold range to go from all-on / all-off to a linear key (which is necessary for translucent graphics). I am assumi...

Re: Peaking a dish alone

The only service where this was an issue was Bounce, which has separate PIDs for legal ID, local ad avail, and program preroll. Escape, Grit, and Laff only generate a single PID for the IDs... so if you are taking one of the other feeds, you can let the receiver automatically set the PIDs based on t...

Re: Peaking a dish alone

We normally use an Arris -- I want to say DSR-4460 but I'm out sick today & don't remember for sure. Initially on Escape, it wasn't picking up the audio PIDs. It was looking for audio on 0x1FFE and obviously not finding it. That problem solved itself while I was hacking on the dish. I'm assuming so...

Re: Animated Graphics with Transparency and ATEM Switchers

There are several ways to accomplish this, but since you're familiar with ProPresenter, I would suggest using that with their alpha keyer module. My previous church ran exactly that, using a BlackMagic UltraStudio connected to the Mac's thunderbolt output; the key and fill outputs go to your switche...

Re: Peaking a dish alone

That's a clever solution -- I'll have to remember it. I switched our Bounce, Laff, and Escape feeds over to HD yesterday (the stations we run here don't carry Grit)... generally fairly painless, and the RF level is much higher now than it was on Friday, so our receivers are staying locked, except fo...

Re: Arris DSR-4460 won't authorize on unencrypted feed

We just deployed a Cobalt 9223 HD encoder and 9990 decoder for a link between our hub and a station in Alabama, where the last-mile circuit is rather flaky -- lots of dropped packets. The +RTP/ARQ option for the encoder lets the decoder request retransmission of lost packets, so unless the circuit r...

Re: Arris DSR-4460 won't authorize on unencrypted feed

So... while I was at it and since it's a nice day outside, it seemed like a good time to peak the satellite dish.

The current resident disagrees.

Re: Arris DSR-4460 won't authorize on unencrypted feed

Over the years I've found that different decoders are better for certain applications than others. We've used Tandberg / Ericsson for satellite downlinks and ASI decoders for years without too much fuss, but the 8200 is troublesome if you're trying to decode an IP stream. Upcoms (yeah, right!) have ...

Re: Arris DSR-4460 won't authorize on unencrypted feed

Well, just updated the firmware on the Sencores (they tended to disappear from Dashboard and become invisible to web browsers... nothing like having to pull and reseat cards to be able to see them). And just loaded the HD license keys... so now I have something to look forward to on Monday.

Re: Arris DSR-4460 won't authorize on unencrypted feed

Yup, we have a bunch of Sencore OpenGear IRDs that need to get HD licenses. I'm not exactly loving the prospect of paying out money to receive feeds in HD that only make air in SD. At least we're a centralcasting hub, so we use the same receivers for a bunch of stations.

Sigh.
