I’m about to have some prototype PCBs made for a DVI-D input module for the Sony 12xx and G series projectors. Is there any interest in a $150 - $200 card that has 24 bit color and supports all of the ATSC resolutions? HDCP will not be supported, but all of the circuitry needed to make the board HDCP compliant will be present (in the unlikely event the design would be licensed in the future).


Depending on the success and interest in the Sony version, different cards could be made for other brands of projectors.

Not ready for it just yet. But good to see that the circuitry for HDCP will be ready to go if it is "licensed" in the future.


Wonder if there will be any HDCP hacking of "similar" projects. No way:D

I am still interested in 1 for my Marquee's,

At this stage we don't know if Jaehong Lee's unit will ever get any further than Korea.


So If you can build a unit then count me in.


Just so you know, the last count on my thread about interest in Jaehong's unit was up to -


Marquee - 34

1292 - 9

G90 - 8

G70 - 8

D50 - 1

XG - 10

PG - 4

1208 / 09 - 5

808 - 7


So that makes - 86


This list needs to be updated, but gives you an idea of the interest.


Cheers

Steve

It will have a place to store the HDCP keys, however no keys will be provided resulting in HDCP encrypted content being unwatchable. The cost of adding the hardware is low, so I put it in the design to support upgrading if a license is obtained later.

Will this be a fully functional card or just the circuit board that we would have to add the appropriate DVI chips to? Also, you said it will have a space for HDCP keys. What exactly does that mean? Could I take the HDCP chip out of a CRT based RPTV and solder it on the card for HDCP support?

Er, right, you need to get a projector first. I'm still waiting for you.:D

The board will be populated with components and ready to use with non-HDCP sources. The "keys" consist of an eeprom image that is avaialble only from the IC vendor to licensed designs. I can't say anything about the posibilities of modifying or "patching" in keys from another device...

XG1352 owner... certainly sounds interesting.


I assume the perceived benefit of this is in avoiding analog attenuation losses / noise pickup in the generally long RGB coax run to the projector. ie: The signal remains in the digital realm until right up close to the projector?


If so, why does this need to be projector specific? Why can't we just have a generic external DVI to RGBHV converter box?
