| Post subject: | Outputing PAL Discs to an NTSC Monitor |
I would love to start collecting PAL LaserDiscs, but as I live in the U.S. of A. my players will play NTSC discs only. I am aware that there were multi-standard players (compatible with both PAL and NTSC discs) sold in Europe, but I have a question. Can they be set to output an NTSC signal? I have a multi-standard DVD player, and it will not only play PAL and NTSC discs, it will output both. Please, are there LD players that can do this as well? STAY AWESOME! |

A player which can reproduce both PAL & NTSC discs will output either PAL or NTSC video, depending on which kind of disc is in it. There is no player with circuitry to convert one to the other, to output NTSC video from a PAL disc, or PAL from an NTSC disc, which is what you seem to be asking. The closest thing would be a player which outputs NTSC 4.43 when an NTSC disc is played, which is not what you want at all. In other words, you will need a TV or monitor which can accept a PAL input, or some kind of standards conversion hardware. |

A friend in the US wanted to watch a PAL laserdisc I owned. I captured the video from the PAL laserdisc to a computer and then converted it using software to NTSC format - one frame at a time - took forever. Then burned it back to a DVD in NTSC format. Not ideal but he was able to watch it. |

I kinda expected that it would be the case, but I still wish it were otherwise. Atari's last game console was the Jaguar. The game cartridges, regardless of region, will detect the standard the console uses. So a PAL release will play perfectly in an NTSC console. If Atari could figure out how how to do it, Pioneer should have been able too. STAY AWESOME! |

If Atari could figure out how how to do it, Pioneer should have been able too. This is the difference between video or images stored as digital data, being output through an analog connexion, as in the case of a video-game console, on the one hand, & video stored as an analog video signal being output through an analog connexion on the other hand. The whole analog video waveform, subcarrier, sync, & all, is recorded directly onto the LaserDisc. No part of it is synthesized or otherwise created by the player, aside from the occasional on-screen display. In principle, all a player need consist of is a crystal oscillator, a motor, a laser, a microscope objective, two solenoid-driven mirrors, a third solenoid to move the lens, comparator circuits to control the three solenoids & a fourth to control the motor, four bandpass filters to separate the video, two analog audio channels, & digital audio, & three FM demodulators, one for video & one for each analog audio channel. (It's much simpler than a VCR.) Nowhere in there is a way to turn one kind of video signal into another. DVD players & video-game consoles, on the other hand, take digital data & use it to synthesize an analog video waveform. Naturally, it's not hard to modify the circuitry which does this to synthesize different kinds of analog waveforms from the same data. The two processes are not comparable in any way. |

All you need is a converter (as Publius suggests) between the monitor/tv to the player. You can input/output any signals you desire. I've seen them do Seacam/PAL/NTSC no problem. |

Thanks for the informative response, although I'm still hoping that someone will have a workable solution. And then there is the whole power supply and refresh issue. NTSC machines released in Japan and the USA use 110 volts/60 hz. PAL machines use 220 volts/50 hz. STAY AWESOME! |

NTSC machines released in Japan and the USA use 110 volts/60 hz. PAL machines use 220 volts/50 hz. Many if not most multistandard LD players have power supplies which will run fine on American current. Sometimes this is a documented feature, & sometimes there's a back-panel switch, but the fact is that modern switching power supplies are often surprisingly indifferent to the specifics of the input current. The "simple solution" to viewing would occur if you have a TV which will correctly display a PAL video signal, in addition to NTSC. This may be an undocumented feature on US models, due to the use of ICs which work for both systems. My HDTV, for reasons unknown, refuses to display a 50 Hz video signal from the component input, but accepts it via composite. (As my only 50 Hz video source is a component test pattern generator, I have no idea whether it correctly decodes PAL colour.) |

I don't have a high-def monitor yet, just my old CRTs. STAY AWESOME! |

Well, if check the middle of the page in the description section it has a little table that says "Converts From" and "Converts To" The "Converts from" section has "NTSC" and "PAL." So it will convert PAL to component or RGB video. Only thing is you need something with a component or RGB input. A computer monitor wouldn't help either since almost none of those will display an interlaced signal from RGB/VGA. A lot of later model Sony, Panasonic and JVC Non-HD CRT TVs have component inputs. But yeah, if you don't have a TV with component inputs, that probably won't help. You can get a Sony WEGA off of craigslist for cheap tho if that helps! |

Here's one that converts PAL A/V to NTSC A/V, composite signal, not component: http://www.ebay.com/itm/PAL-NTSC-TV-vid ... 20b60c63b9 If you have an NTSC monitor that will accept component 480p, which it seems you probably don't, the DVDO HD and HD+ upconverters will accept PAL signals and convert to 480p. They also convert to 720, 1080, and a bunch of PC image formats, for future upgrading of your set. http://www.ebay.com/itm/DVDO-DVD0-iscan ... 19c99906be They are the least expensive of the DVDOs that do this. The earlier models do not, such as Pro or Ultra. This is what I use to watch PAL LDs played on my CLD-D515 upconverted to 1080. If you have a standard TV set, another way is to run the signal through a PAL-NTSC VCR set on PAL input and NTSC output, and it will work. This is what I had to do before getting the DVDO unit. It helps if you need the VCR for PAL tapes like I did. Of course, first you need to grab yourself a PAL/NTSC player like the CLD-D515, or other Pioneer model. Sony made several as well. |
