HDMI isilencer

[jimfisheye]

I'd like to see someone take one of those isilencer's apart and see exactly what sort of circuit (if any) is inside.

Or just capture before and after recordings of the digital audio stream through it.

Does the thing have an LED? If yes, my guess for the circuit is a resistor and LED tapping power off the HDMI input to light the LED. Maybe a small capacitor to ground to cure the noise the thing would introduce that would otherwise break the ability to even pass the HDMI signal.
Again, just a guess.

Yeah. Now I use a Canon inkjet that will print to (white) inkjet printable discs. Looks like factory if you get the image scan right (I use PhotoShop).
Don't print so many these days, but sometimes for a backup disc. Canon has a utility for printing to inkjet printable discs.

Ahh, the good old days of trading CD-R boots... from sharpie-labeled, to printed labels (the worst of all worlds with respect to disc stability and possible damage to the player), to printable discs.

The problem with the inkjet-printable discs are (1) spill some water and you have a horrific mess when the ink runs, and (2) even dry, the ink can flake off over time and gum up the insides of the player, especially if you play a lot of inkjet-printed discs.

That's why back in 2005 I purchased a Primera Accent II CD/DVD laminator. It heat-seals the top of a printed CD with a layer of clear film, thus making it water-tight and the ink no longer flakes off. It also makes the discs look much nicer, with a glossy surface. I still have it, although I don't use it very often.

All this stuff is child's play, my system really didn't come alive until I got my hands on a Rockwell Retro Encabulator - thanks to the revolutionary implementation of hydrocoptic marzel vanes, it has completely solved all of my problems produced by modial interaction of magneto reluctance and capacitive duractance, with almost zero side-fumbling.

Me .....
I've got an orgone accumulator
And it makes me feel greater
I'll see you sometime later
When I'm through with my accumulator

It's no social integrator
It's a one man isolator
It's a back brain stimulator
It's a cerebral vibrator
Of orgones, of orgones, orgones

Then i went to the discs with burnable label sides.

I remember doing that back when. That didn't last long but I worked OK.

If someone was interested enough they could purchase one and have it drop shipped to Amir at
ASR to measure and possibly disect? Then he would ship it back to the purchaser when done.
I bet he'd love to see that it really does.

Doesnt he have an issue with his equipment testing HDMI? Or maybe he just chooses not to when there is S/PDIF available.

Now you notice you had the thing bypassed the whole time. There was no change at all.

That's funny. I've actually done that. Most recently I get in a big huff about the hissing that I hear. When I turn off the music, it's my tinnitus...lol. So for me, I'm not sure it can get any better in reality.

Yeah me too. That's what we need. An isilencer for tinnitus. I would buy that.

If you get quality inkjet printable discs should be no problem. I confess I don't play discs enough to worry about any flaking, though I've never seen it happen.

Amen, Brother.

I’ve seen obvious degradation in an HDMI connection that wasn’t catastrophic. I have a device called a “cloner” that sits in the HDMI path and records the sognal going through it to a thumb drive. Sort of a digital VCR. When it works, it does a pretty good job.

I hooked it up one time and the picture was significantly darker than a straight through connection. I have no idea what was going on, but the picture was there but certainly not right.

Then there's likely something specific going on, such as a mismatch in the E-EDID of the display and cloner (it must merge them to combine its capabilities with those of the display in the E-EDID sent to the source) making the source send out a different signal than usual, or the cloner misinterpreting the quantization range, thinking a full range source is limited range. E-EDID problems are common when signals are split or run through an intermediary device.

In my last job, I worked at a place that made their own discs and had a color laser printer for them. I wasn’t directly involved in that end of the facility, so I don’t know what the printer was.

Your tax dollars at work.

I’ll admit, I haven’t poked into the weeds of HDMI like I did NTSC and PAL back in the day, so most of that went over my head. Maybe someday I’ll get a decent textbook. I’m reasonably conversant on MPEG, but what’s going on in an HDMI cable isn’t something I’ve had much exposure to.

FWIW, I used it last week and everything went fine.

I still burn a handful of discs now and then. Latest project is copying my laserdiscs before all the players die. I am on my second Epson printer that also prints discs. I have a file drawer full of blanks.

At one time, I had a stick-on label system. It had a device that would center the label on the disc, and it worked well until the glue dried out.

Just curious, can you tell me your process and equipment for copying your laserdiscs?
Hopefully, I will be undertaking that same task later this year.
I plan on retiring by summer's end
