GeForce 6100 GPU, no support for TV encoder

I'm reading that the GeForce 6100 GPU does not support a TV encoder. I'm hazy, been awhile since I read up on it, but if I use a ATI Theater Pro 550 based card, I'm OK, right? I think the ATI card does all of the TV functions and just passes the processed picture and sound on to the onboard video. I guess I want to know exactly what does a onboard video do if it does support TV encoding?.
 
Yes, if you have a separate tuner card like a Hauppage or ATI your video card does not need to have any encoding features of its own.

If you don't have a separate TV capture card.


Door #1: graphics card has VIVO/encoder and you have a TV capture card

You attach cable, VCR, whatever to the TV capture card, it records, it feeds frames to the video card either as bitmap data or using a fancy overlay capability.

The video in / encoder part of your graphics card sits idle, twiddling its thumbs and whistling off-key.


Door #2: graphics card has no input/encoder and you have a TV capture card

You attach cable, VCR, whatever to the TV capture card, it records, it feeds frames to the video card either as bitmap data or using a fancy overlay capability.

The non-existent video in / encoder part of your graphics card sits non-existent, not twiddling its thumbs and unable to whistle off-key.


Door #3: graphics card has VIVO/encoder and you do not have a TV capture card

You attach cable, VCR, whatever to the Video In connector of your graphics card. It tossess away its half-read copy of Entertainment Weekly and starts recording.


Door #4: graphics card has no input/encoder and you have no TV capture card

You go to attach cable, VCR, whatever to the PC and try without success to jam the connector into a USB port. No TV for you!
 
OK, thanks man. I appreciate your post. Believe it or not, I have installed a ATI 550 and a ATI HDTV tuner card before. I just have these holes in my knowledge about some terms and how some things work together. Just enough knowledge to make me dangerous I guess
 
Gad to help, the above was of course an excessive answer but whimsy overcomes tact now and then 🙂

It wasn't too long ago that you needed a VGA card with a VESA connector and hardware video overlay or you couldn't see what you recorded. Now everything is fast enough that it just works.
 
I guess some of my confusion was as a result of reading a review about the Biostar Tforce6100 AM2 board where it says no tv encoding and no HD playback, but then it talks about playing a HD movie on it to test the Purevideo function. I missed the part where it says the board will drop it back down to standard 4:3 definition. I hate it when I miss something.
 
What they were getting at, I think, was that the 6100 doesn't have hardware assistance for decoding HD video, so the CPU has to do all the work.

Any system you put together with a CPU over 1 GHz will have no problem playing back standard resolution TV, divx and DVDs but decoding some high def modes puts a lot more strain on the CPU if the video card doesn't do some of the work.
