A RAW decoded digital TV stream would be 601 video (16-bit 4:4:4 Y'CbCr) at PAL SD resolution/refresh would be 720x288x16x50 = 158MBit which would be about manageable with USB2.0 HS


Hate to disagree, but DVB and DVD are all 4:2:0, so it's rather:
Y: 720x576x25x8 = 82,944,000 bps
'Cb: 360x288x25x8 = 20,736,000 bps
Cr: dito = 20,736,000 bps
sum = 124,416,000 bps
as long as you keep it Y'CbCr, RGB 4:4:4 is ~250 Mbps.

Count me in for another 10€. I live in Germany and could very well handle the transaction and sending to Chris. I don't think I'll ever buy a Deneb (don't do that much with Amy really), but like to donate to something productive. I think the best would be to let Chris select the specific adapter first - it might get pretty hard to get low level developer specs for most parts...

You could give us Angelina Jolie's cellphone number and the IP address to connect to her wireless shower-cam.


For a start.  :roflmao:

Just got a DeLock 61644 USB-DVI adapter for evaluation with our notebooks (all are docking and TFT equipped, but DVI-capable machines are out of the budget). We'll be testing it in the next couple of days, afterwards I can offer it for extended testing, maybe it's of use.

This adapter was specifically recommended by our hardware provider - let's see what it can accomplish.

The DeLock really uses the same chip, but it's a DL-160 - so the high resolutions should work as advertised/mentioned in the 'manual'. But I bet it's the very same board design (=reference design from chip manufacturer).

Nice to see progress here, even if everything is open still.

I started with x86 assembler many years ago, but detested it so much I couldn't stay on - it's like riding an open oxcart after knowing the 'Rolls Royce' 68k version...
