Hacking a VGA-connection in a DVD-player

Posted on Thursday, October 12, 2006 10:16 PM
I own several players, some for daily use, others for special occasions or if one of the others might kick te bucket for some reason. One of those daily players is an "Encore DVD-43031", and sits in my bedroom, as I like to watch a movie or anime now and then before I go to sleep.
I connected it through a VGA-box to a computer monitor I had lying around, but I wasn't very satisfied with the picture quality. The conversion from composite to VGA made the image very bright, but toying with the brightness and the settings of the VGA-box didn't do much good.
The VGA-box also has S-video and YUV-connections, so I thought I'd try a YUV->VGA conversion.

The image improved a little, but still quite bright and saturated, so I checked the setup of the player for more options.
"Hm, let's see what we have here... Video, S-Video, RGB, PC-VGA, YUV... Hold on, PC-VGA? That would be nice; let's fire up the soldering iron!"
Okay, technically it's not really a hack, since it's already built into the firmware, but not everyone is very keen on drilling holes in their DVD-player. ;)

It's quite logical actually, as most cheap DVD-players tend to be built around a PC-type DVD-pickup, and driven by a small MPEG-decoder with everything but the kitchen sink built in.
The PCB had an unconnected connector with R, G, B, H-sync and V-sync next to it, so I removed the SCART-connector (who needs that when the player already has connections for Composite, S-video and YPbPr), drilled some extra holes and mounted a VGA-connector instead, using the wires that used to lead to the SCART-PCB.
Hooked it up to the monitor without the VGA-box, and presto; a stable image without being too bright or saturated. Here are some pictures I took during the build.

For sound, you get 5.1 analog outputs and both TosLink and S/P-DIF digital outputs on this puppy, so that was good to begin with.
Now, if you'll excuse me; I have NieA under 7 to finish.

Cheers, K.

Wait... does the box actually say "SCRAT output"?! WTF is a scrat? :D

And: that's pretty nice hackery you done there.. Marli'd kill me if I took my soldering iron to my DVD player :)

Yes, it says SCRAT. Hey, it's a Made-in-Taiwan piece of kit, what do you expect? ;)

Just to keep people from wondering (I was confused when I got a new DVD player at first as well), SCART is not a signal-format. Basically, SCART is a connection format, which can send all signals your player supports over its cable.

Many DVD players and TVs support SVHS over SCART, so don't bother with plugging in a lot of seperate cables (usually to the front of a TV = ugly) when your TV and DVD player are reasonably modern.
Just make sure that if your TV has multiple connections that you connect it to the SCART that supports SVHS. (I knew there was a use for those TV manuals, besides keeping the coffeetable level ;)

And, to correct you: SVHS is a certain type of videotape; not a connection.
I believe you're referring to what's usually on the 4-pin miniDIN-connection, better known as S-video. ;)

But indeed, SCART holds multiple signals, and depending on the settings of the player, puts the correct signals on the correct pins.
However; I love to muck around with separate cables (somewhat more reliable, and the majority of my equipment is fitted that way), so doing away with the SCART-connector wasn't too hard. ;)

@Cailin.. in "Wait... does the box actually say "SCRAT output"?! WTF is a scrat? :D "

Well.. haven't you seen Ice Age yet? "Scrat" is that little prehistorical squirrel or something.. so.. i think "SCRAT Output" means that it is a safe place for him to put his nuts on.. lool
