Calling all video experts.... Some of you might remember me mentioning this HD laserdisc player in a previous thread: http://www.assemblergames.com/forums/showthread.php?t=27207&page=2 It was sold and shipped but the Buyer is having some problems and I wanted to come here for advice. It appears the the picture quality is blurry overall and we can't seem to find the source of the problem. Here is some info about the LD player (http://www.laserdiscarchive.co.uk/laserdisc_archive/pioneer/pioneer_hld-1000/pioneer_hld-1000.htm): "For NTSC LD there is a Y/C output. NTSC video specs are 425-line resolution and a 51db signal to noise figure with Hi-Vision LD rated at 650 lines." Standard definition LDs seem to work fine, but there is a drop in quality for HD laserdiscs. He's using a Sony VPL-VW200, LG plasma 60PK550 and Panasonic plasma 50G20. The decoder is a Sony MSC-4000 that was tested with the LD player. Here are some sample outputs: As you can see there is ghosting around the numbers and extra lines and a loss of resolution overall. The same ghosting appears on Japanese kanji subtitles. It's not the MSC-4000 because the picture is sharp in the menu. The loss of quality is only with the actual LD output. He's running the HD over a YUV output, like I said the non-HD laserdiscs over composite work fine. Has anyone experienced problems like this? Any ideas what the source of the problem could be? Something internal issue with the LD player itself? Something that's not compatible with the setup? Any advice or troubleshooting would be greatly appreciated. Thanks!
What kind of tv is he using? lcd ? plasma? The ghosting looks like interference either from using the 100v device on a 120v line, or a cable without enough shielding.
yuv upscaled to a huge plasma? You can only do so much. I'd tell him to try it on a another tv, and if it looks fine it's his set.
it being a plasma or LCD won't make a difference. http://www.assemblergames.com/forums/showpost.php?p=417827&postcount=29 you need a Muse decoder for it to work on an HD-TV. That's why normal LD works and Hi-Vision doesn't. also, he's got a G20? <3<3 Can I come over?
Yeah, that's the Sony MSC-4000, as mentioned. I would guess there's either some interference between the LD player and the decoder, or the LD players on the fritz, or the decoder's on the fritz. Have you tried running a non-HD laserdisc over component?
That's what's hard to understand.... I've seen situations where a HD laserdisc player will play regular LDs fine but not work at all with HD laserdiscs. The player simply won't start the disc or the player just shuts down, even tho it plays standard definition LDs just fine. It's usually all or nothing. I've never seen a situation where it works but gives you a worse picture than SD.
He's tested it on all 3 of his TVs.....but then again 2 are plasma and one is a projector. Here's what he's saying: [FONT="]- blurry pic - blurry OSD - columns on left side (sometimes on right side) - can be effect of "safe border" which is invisible normally, but I switched off overscan, and its still there - affects only HD disc over MUSE output - is inside the player (because digital STILL freezes it as well, I mean, floating distortion will be freezed as well, via digital pause circuits) - is inside the player at place where OSD is already put into the picture, so both OSD and picture is affected - is nothing to do with MSC , because OSD from MSC is sharp and nice[/FONT]
Pics do appear to show ghosting. You mentioned regular laser discs show a crisp image? I think it has something to do with "HD Squeezed" laser discs. The anamorphic image trying to be resized not working out. How do the images look on a CRT?
Sounds like the Muse decoder to me. The ghosting could be of the interlacing going wrong. Hi-Vision/Muse depends heavily on interlacing. Does this player have different pickups/lasers for the types of discs it supports? And is it able to display the contents of a Hi-Vision disc through another connection then YUV?
Hi-vision is not standard HD right? It's 1125 so it's not going to look right. Japanese TV might support muse but I doubt foreign market will.
It's been pointed out a couple of times that he's got a Sony MSC-4000 MUSE decoder. Apparently the menu for this unit looks sharp over YUV, but the LD content itself doesn't.
