Hello!
I took a gamble on yahoo auctions and pulled the trigger on a LD-V2020 player listed as junk/untested for 15$, as I saw almost no information about it and I was a bit curious...also it looks to me pretty rad ;P
So, the player is actually working (yay!) and while I eventually realized it's probably just a variant of a CLD-95/CLD-919 (Japanese model) it was definitively interesting taking a look!

So, the player has no buttons/commands, except for the ones visible on the front panel; A/B side selector, repeat mode, audi off, disk insert/remove, remote input on/off and of course the main switch.
The lower cover is just a cover, no buttons hidden...the unit philosophy is clearly focused on "if it's not there, it won't break"
Everything is metal, and there is convenient lid on the top of th elaser pickup, so it can be cleaned without removing anything.
on the back, not much, two video output, one genlock overlay input, LDP remote input and L/R analog audio RCA.

Using a wired remote provide access the all the functions:

now, the internals:

what do you guys think? Does it share parts with the CLD-95/97 players? My guess this is a 1991 player, but could't find a year stamp yet....too bad it has no digital audio PCB :( |

Hello,
disclaimer: I'm not involved with the below mentioned company, the goal of this post is to share what I recently discovered and see if the community may have interest and possibly combine effort, so we may end with a solution to expand options for upscalers with bad comb filters, using a separate unit... really hope this will be useful somehow!
So, while looking for a dedicated comb filter and digital converter, I stumbled upon this article by Daniel Ogilvie, from SingMai https://www.singmai.com :
https://www.eetimes.com/how-fpgas-are-breathing-new-life-into-the-analog-video-format/#
I contacted him, and turns out he has a FPGA-based product he's updating these days, the SM03 video decoder, as he's focusing on analog sources like VHS, so after mentioning the LD community and upscaler/filter problem, he confirmed interest in working on the product update including testing LDs players as well.
So, my understanding is he's available having people here testing it, in case providing feedback so he can improve the product specifically for the LD case... my guts tells me given it's FPGA, the process may indeed allow few reiterations and maybe feature requests?
I provided my availability of course, as I do have a pretty decent setup with multiple players, scalers(DVO/Lumagen/Micomsoft) and projector/IPS monitors, but I believe there are people here who may have precise ideas about what a comb filter/converter for LD should do... so, what do you guys think?
Here I uploaded the data sheet http://www.netpacket.it/LDs/SM03_brochure.pdf ,.., maybe that will already show if there are important features missing? It includes contacts for those interested in reaching out to him etc
Thanks for anyone chiming in and helping, I really hope we may end with a new solution :)

Hi, sorry for the late reply, got pretty caught at work, good news though, an evaluation pre-production unit will be sent to me on Monday.
What happened in the meanwhile, Daniel added an analog audio processing capability (RCA L/R input), so the final hardware design got updated. Other manufacturing-related issues contributed to the delay.
Anyway, I should be able to post first impressions/screenshots in aprox two weeks...fingers crossed! |
