Hello There, I am based in the U.K How can one purchase the EVAL-ADV7842-7511P board. I have heard good things about this piece of kit for laserdisc playback. Unfortunately there seems to be none available for non HDMi Adopters. Thanks in advance. Gus

They have been out of stock for a while, but it seems like they will hopefully be restocked soon. |

We already have a thread mentioning this board: Squeezing every bit of detail out of a laserdisc Julien |

I have the same problem as you. I purchased one board but then they asked me a written proof of the fact that I was an HDMI adopter and cancelled my order afterwards.  Laurent |

You have to order EVAL-ADV7842-7511P not EVAL-ADV7842-7511 |

Sadly it seems they are now aware that the Laserdisc community are getting hold of the Eval board. They're now implementing a stricter policy as to who can purchase it. It's a shame because of other commitments. I did not act sooner having heard about it's performance way back then. Gus |

So wait, why won't they sell to the LD people???? What was this product for that we are trying to use for LDs???? |

It's an evaluation board, designed to show off the capabilities of their chip to people who are looking at building hardware with that chip. As such it probably has small production runs and might well be made at a loss (on the expectation that the orders they receive for the thousands of chips will make up for it). It certainly won't have been intended to be an end-user product. |

I see they have now updated the official page for, stating purchasers must also be an HDMI adopter. I wouldn't be too concerned, there will (hopefully) be a better option in the future. You had to have a computer connected to the board. There was someone selling a mod though that just allowed you to press a button, but I think that put the total around $350. For that price, I think you would be better off putting that towards a CLD-R7G if the combfilter in your display is that bad. |

This was a cheaper option if you didn't have a Lumagen 2144 which has the same chip. |

I'll do a more in-depth search after working out. But how do you become an HDMI adopter??? Is it a hard thing to do?? I take it you need more than a business license? |

HDMi Adopter Licence starts from $10.000 a year. |

Yep that's correct no scaling this would only handle the composite 480i from your Laserdisc and then output hdmi 480i or 480p into what ever 1080p or 4k video scaler you have to your display. |

DigiKey will cancel your order, for either version, if you're not an HDMI adopter which is prohibitively expensive for this purpose. They canceled mine 2x even after phone calls and emails! I have yet to call ADV directly since they're not far from me. Maybe one day. If you want to stay on the bleeding edge, Peter has already moved onto the next toy. EVAL is sooooo last month. The same ADV chip (7842 or 78xx) is in a cheaper box called the Extron DSC-301 HD that is easily attainable. It isn't the bees knees but its good. The same chip is probably better implemented in the Lumagen but at a higher cost of course. On my set up I preferred the C2. Maybe it was because I already had it. My 2015 Sony 4K also is no slouch and between that and the C2 the Extron didn't do anything better than what I already had going IMO. I also have a Denon AVR with a 2D ADV comb filter that does a really great job on LD and sends it out 1080p/24 over HDMI. The interest in the EVAL is that you can output 480i over HDMI and use an external deinterlacer/scaler while having total control over the Comb Filter settings in the ADV chip. Downside it that it needs to be connected to a PC running a terminal software that connects to the board via USB/RS232. All settings are changed via software. Yes there are some work arounds but just more tech to deal with. Not my cup of tea. The C2, however, gives you some control over the comb filter and had 2 deinterlacing chips to choose from. Both outdated, sure but not total crap either. The C2 is really hard to beat but very hard to find one. For real-time decoding of LD on newer (2010+) displays your TV's composite input, C2, Lumagen, DVDO, Faroudja etc are your best options as far as actually finding something beyond a DVD recorder. All of these options have their pros/cons. Lately I'm just watching my movies using the TV's composite input and I'm pretty happy
