Re: Old analog Gear, need manuals, etc.

Sorry, I don't remember the type of connectors. As I recall, they were Y / R-Y / B-Y component video plus the key signal, so yes -- the video quality was much better than componsite.

Re: Alien Representation of Dynamic Range

Thinking more broadly, converting HDR images to show on a real-world display is a non-trivial issue. As I recall, the human eye can generally discern about 14-15 f-stops of dynamic range; a good monitor can display about a 10 f-stop dynamic range. So if you have an image with broader dynamic range l...

Re: Alien Representation of Dynamic Range

Suppose that we have an HDR radiance map...which has a dynamic range (luminance) of 5.5 (1:343,512) and that we need to observe the radiance map through a display which has a dynamic range of 2.4 (1:256, 8-bits [36]). What system is this of prescribing dynamic range with a decimal number like that?...

Re: Old analog Gear, need manuals, etc.

...i've not been blessed with an Abekas A62/72 disc recorder (i'm looking). "Blessing" is not necessarily a concept I associate with the A62! Back when I was doing freelance maintenance for a local production house, I was tasked with getting a used A62 running -- they bought the thing as-is. Back w...

...Now i'm on the hunt for a manual. Do you happen to still have access to yours... I'm sorry Jason, our technical manuals and extender boards went with our A51s and combiners ten years ago when we converted our production control to HD. So far I've been able to answer your questions from memory an...

Re: Old analog Gear, need manuals, etc.

That doesn't sound good at all. One off-the-wall idea: if I remember right, the A51 could run in either NTSC or PAL, and you could change the standard in the SETUP OUTPUT menu. If your A51 is trying to run in PAL, you might get the result you're seeing. Aside from playing havoc with the video output...

...must one have a Black Burst and synced input going into the Abekas A51+ in order to see the color bar outputs? I believe the A51 does need reference, though it's been quite a few years. We never tried using it without a reference input, since keying a non-synchronous source in our production swi...

Re: Harmonic encoders

If you have an older IRD kicking around like an Upcom or Tandberg that has IP input, it's very likely that you can point an IP stream from the Electra 9200 to that, and take ASI from the IRD's output. If you don't want to spend a lot of money right now, that could be a practical workaround.

Re: Repack Poll for the TV guys here.

I would also be curious about how many stations are getting higher than normal viewer complaints about reception -- especially stations that didn't need to change during the repack.

Re: Any love for Thor encoders?

Welcome to the forum! My impression was that Thor is mainly found in CATV and MATV environments -- I have never seen it in a television station (but things do change). I suppose it greatly depends on what you want to do: if you're in France, you probably don't care much about ATSC encoding. :lol: Jeff

Re: No National EAS test in 2020

Good. Our station got a great deal of angry viewer reaction last year, mainly from people convinced that this was a system for transmitting political propaganda. The way things are going right now, that's something we don't need to repeat.

Our 9240s are four years old next month, and they're already end of life? :x

Sounds like you needed a vending machine full of Caf-Pow. Funny -- we used to have a master control operator who reminded me greatly of Abby. Really sweet, and really good at the job.
