Thanks for that, I too am aware of VHS-Decode (something I want to visit eagerly)! However I was referring to the PCBs and KiCad files (if i am correct) to manufacture them physically and make them fully functional. But because of the vast amount on the github, I don't know what files to use if I ever were to approach a manufacturer online or abroad |

If you look under the "capture hardware" section (specifically "Domesday Duplicator"), you should find what you need. There is even a link to order it from PCBway. You can order it populated or not populated. https://www.pcbway.com/project/shareproject/DoomsDayDuplicator_Rev_3.html You can also find some people selling premade and tested kits. |

I have a doubt... reading this page (https://bitcrush.io/laserwiki/index.php ... ng_Process) it seems that the raw capture is limited only to video... as my memory lacks (a lot) I can't remember IF the laserdisc audio is included in the raw capture, and in case, WHICH one(s) - analog, PCM, AC-3, DTS... |

All of the audio is captured and stored in the RF. Analog and PCM are for sure decodable, i think AC-3 is, and unsure about DTS. |

Thanks! Curious to know now if AC-3 and DTS are effectively decoded now, or if there are plans to decode them in the future. |

DTS also mentioned on the wiki https://github.com/happycube/ld-decode/ ... rocess-efm The ld-decode wiki hasn't been updated, but --AC3 is shown in the help: Code: Select all $ld-decode --help |

Someone had fund adding a RF out to a HLD-X9 for the Domesday Duplicator! https://page.auctions.yahoo.co.jp/jp/au ... 1132987673 Attachment: Attachment: Julien |

That's the future of LaserDisc. It seems realistic that in the forthcoming years we will probably have real-time capable ld-decode in an embedded/dedicated system. "DD RF out mod" will be something like the AC3RF out mod now. And we won't be arguing about comb filters anymore, but about spindle motors, tracking servos, "cleanest RF signal" etc. So, this X9 is future-proof! admin wrote: Someone had fund adding a RF out to a HLD-X9 for the Domesday Duplicator!

So someone is going to "Domesday duplicate" all 65,000+ LD titles? Doubt it. |
