Re: 2017 Eclipse

I'd take a nap too, but my employer might not appreciate it! The view from our centralcasting control room is remarkable: the networks are doing extensive special report coverage of "THE GREAT AMERICAN ECLIPSE", as David Muir insists on calling it. I haven't heard such a combination of breathless in...

2017 Eclipse

And this morning I finally got the question I've been expecting for a week: "Do we have satellite backup for this afternoon when the sun goes out?"

Sigh.

Re: How is it done?

Welcome to the forum, Florian! One of the key points about live digital television is that is it not generally file-based; instead, you are feeding some video source (a camera, the output of a switcher, for example) into an encoder that converts the audio and video into a real-time transport stream ...

Re: PRINTED CIRCUIT BOARD MANU.

Thanks, as I know PCB stands for Printed Circuit Board is a thin board made of fiberglass, composite epoxy, or other laminate material. It’s connected with different components such as transistors, resistors, and integrated circuits. If your posts are an example of your company's services, you're t...

Re: Compression Ratios

It's your first answer: the data compression ratio is the proportion of uncompressed size or rate to the compressed size or rate. Wikipedia's article goes into more detail. Where many people get confused is on the difference between data compression versus audio level compression -- the two are enti...

Re: Old analog Gear, need manuals, etc.

Ok, so with the combined powers of a Horita BSG-50 blackburst generator, and For-A FA210 time base corrector, I can really do some wacky stuff to video! These warps are ridiculous and amazing, it's like the controls go from "oh, this is pretty subtle" to "huh, this has very little resemblance to th...

Re: Sony BVH-2180-PS: Servo Error

Hallo, I got both Manuals now and started a lot of measuring... On TP 15 there seems to be nothing... But one thing seems strange ( maybe ) I have an NTSC version of CF-17 an when I put this board in, I get the same error ( after 15 seconds switch of and system error... Is this ok or does it mean t...

Re: Old analog Gear, need manuals, etc.

Yup. We used to have an early animation system that ran on a 386 with optional math co-processor chip. It would take about five minutes to render a frame; when it had finished, it readied up the BVH-2000, performed a one-frame insert edit, then took the VTR back out of standby... and the whole proce...

Hi Jeff, many thanks, now I tried this test. When press the button below the switches on CD-17 and then Standby, the drum starts to rotate but makes a clickering sound... clac clac clac.... about 3 to 4 times per second. this sound is not there in normal operation mode ( 000 instead of D00 ) In D00...

Re: Old analog Gear, need manuals, etc.

Hmm, right now I've just been planning on plugging stuff like VCRs and old video game consoles into it. I'd love an HDMI -> NTSC SD converter that would take blackburst, but something tells me that's not the sort of thing I'd be able to find on ebay for a $30 price tag :P. You will absolutely need ...

Re: Old analog Gear, need manuals, etc.

After doing some research, I picked up a Horita BSG-50 Blackburst Generator for $30 off ebay, and a For.A FA-210 Time Base Corrector for a similar price. If I understand everything correctly, the blackburst generator would go into both the TBC and the A51, and my input video would go into the TBC a...

Re: Sony BVH-2180-PS: Servo Error

Good morning Martin, I double-checked the test procedure on the machine in the control room, and discovered that I forgot a step: after you set the test mode ("D 0 0") and press the test button on the CD-17 board, you need to press the STANDBY button on the front panel. Then you can take a look at t...

Re: Old analog Gear, need manuals, etc.

Thanks for all this info btw, I'm sure I'll have more questions once this thing gets up and running. You mentioned you have the user's manual, yeah? Is there like an introductory tutorial? The operator's manual doesn't exactly have a tutorial so much as it is the tutorial. Once you get past the ste...

Re: Old analog Gear, need manuals, etc.

Could you provide a photo of the one on your machine? It sounds like the sort of thing I could make with some sheet acrylic and a laser cutter. Sorry... we haven't had these machines since we converted our plant from analog to digital nearly ten years ago. But yes, you should be able to make it pre...
