This means that the video card must be capable of outputting the signal as a component signal. Any ATI Radeon 8500 or above has the hardware to do this, and I think the 6-series nVidia cards can as well. In Windows with a Radeon it only takes a registry entry to enable it if you're using late-ish drivers. I'd assume one could do something similar with the nVidias under Windows. However I doubt if the Linux drivers for ATI or nVidia have this implemented. Could I hurt anything by using it? Well, you can't just plug it in and expect it to work. It won't, and you could damage your TV. But if the drivers will output component signals AND you create the proper modelines, then no, it won't hurt a thing, it'll just work.

Re: [mythtv-users] VGA to Component adaptors
There is a thread on nvnews about the component out in Linux, but no real conclusions yay or nay. Someone here (Cory?) built his own, but I never did get all the details. Seemed pretty simple from what I remember. Ooops... I just re-read what I was accused of accomplishing. The circuit I built converterted RGBHV (i.e. VGA) at 480i frequencies to *composite* (and s-vid). It wasn't component. The RGBHV-component is a much easier circuit, though. There are lots of instructions on the 'net for how to build a transcoder for that. The toughest part is figuring out which gain matrix is correct for RGB-YPbPr... there seem to be a few different ones floating about. Also, one minor caveat that I think most people happily ignore is that component video is supposed to have bipolar sync signals. Unlike the TTL-like signals of RGBHV, component sync is supposed to be nominally zero, go negative for a bit, then posititive for a bit, then back to zero. It keeps the DC level of the sync signal zero so DC restoring circuits aren't necessary. I don't recall any of the DIY transcoders doing that, but they seem to work all the same. -Cory * * Cory Papenfuss* * Electrical Engineering candidate Ph.D. graduate student * * Virginia Polytechnic Institute and State University * * ___ mythtv-users mailing list mythtv-users@mythtv.org http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users

I've read a bit about building your own, and it seems pretty straight forward, but then I see this: http://www.national-tech.com/catalog/vgatorcacomponentvideocable.htm which looks pretty cheap, but they all say 'not intended for use with a computer' which seems odd since it is a VGA connector. My question is: what are people using for vga-component, and how do they like the quality? Thanks for any and all info. Tom I actually picked up a RCA VHDC300 off of eBay recently for a pretty cheap price. I got it setup last night and the picture quality is much better on my HDTV than before with just svideo. I still have to do some tweaking to compensate for a slight horizontal overscan, but I've been pretty happy with it so far. Before purchasing, I tried to find information online about its use in this application (using it for computer applications), and wasn't able to find too much about it. I did see a couple posts on a forum about how it may only work well with 540p/1080i modelines, but I have not yet tested this statement.

Simple is fairly true as far as the hardware goes (a surface-mount chip, a few resistors, crystal, and connectors). The harder part was finding a video card that did interlacing at 480i frequencies.

Re: [mythtv-users] VGA to Component adaptors
I have the same card, GF4-MX440. Care to share your circuit/parts list? :) Actually, it doesn't have much to do with the vid card (as long as it'll output 15kHz/60Hz/interlaced). The parts list is basically the same as some of the homebrew converters on the 'net that use the AD724 chip. Take a search of the archives for my previous posts and google on the chip. I ended up cutting a PCB because I've got access to a board mill. You could probably do it dead-bug style and get pretty good quality. Just put it in an opaque box so nobody can see it... :) -Cory * * Cory Papenfuss* * Electrical Engineering candidate Ph.D. graduate student * * Virginia Polytechnic Institute and State University * * ___ mythtv-users mailing list mythtv-users@mythtv.org http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users
Re: [mythtv-users] VGA to Component adaptors
I have heard people rave about their Audio Authority VGA-to-Component adapters http://www.digitalconnection.com/products/video/9a60.asp I echo the rave. I use one for 1080i output from my NVidia card. I switched from the NVidia component dongle to the AA9A60 because of the troubles with setup of Xorg and Nvidia with this dongle. I've been happy ever since. Picture output is nearly identical between the two. -Ack ___ mythtv-users mailing list mythtv-users@mythtv.org http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users
