In Reply to: RE: upconverting laser disc? posted by Victorymoto on May 19, 2009 at 08:08:50
Yes, you can send the output from a laserdisc player to a video processor to be upconverted. The player's output will be 480i and, depending on your video processor and display, will be interpolated to a higher resolution such as 720p, 1080i or 1080p.
While many laserdisc players had composite and S-video outputs, the video recorded on laserdiscs was composite: a comb filter was used to provide the S-video output. There were probably about 6 laserdisc players that actually realized S-video outputs which provided better picture quality, in their time, than if one just allowed the display to convert the composite output (the Pioneer CLD-79, CLD-97 and CLD-99, the Japanese market Pioneer X0 and X1 and a Runco THX certified player -- which was a modified Pioneer).
Follow Ups:
The question was whether the comb filter in the player was any better than the one in your TV. They're both processing the same composite video signal. I would expect that modern TVs have much better comb filters than were practical in the '90s, so don't worry about finding a player with S-video out.
I watched Natural Born Killers (the boxed set) recently, upconverted on a 720p Sony 16x9 CRT, and I was impressed by how good it looked and sounded.
Now, S/PDIF output is a rare and useful feature which I have not found on any thrift store laserdisc player. My Hitachi (really a Pioneer) had provision on the circuit board for an "export" version with S/PDIF out, so I just had to add a buffer circuit and drill a hole in the back panel. It means I can enjoy DTS laserdiscs at higher bitrates than (probably) any DVD. And it avoids an extra digital to analog to digital conversion stage for Dolby Surround or Prologic sources, which can't be a bad thing.
It also means I can potentially capture the PCM or DTS audio stream, which is valuable if the DVD or Bluray versions of a movie have been mutilated because of music licensing.
I made a poopsie!
Laserdisc is 425i, not 480i. Sorry 'bout dat.
