HDTV cards

[nrj0122]

I'm looking at the HDTV cards of Access DTV and Hipix DTV 200 (or MYHD MDP-120, which replaced the HiPix DTV 200 I guess). And what I want to know is if they also can record the analog signal coming in onto the PC hard drive.

The HiPix card info summary says that it converts all analog signals coming in to the HDTV format/signal which then can be displayed onto your PC monitor or TV-so if this is true, then no matter what type of station you "tune" in (HDTV or Analog) one should be able to record this to the hard drive? Because it does record HDTV signals onto the hard drive.

Anyone know any more info on the capablities of the ATI Wonder HD? besides the general specs it gives on their website?

I say go Myhd, hipix is no longer supported, and the new ati is software only where the myhd is hardware based.

errrrr sort of... As I said in your other post asking about saving Analog with the HDtv cards, you have to encode it.. saving HDtv signals is not he same as analog, not even close.. the HDtv sort of flows in as a stream and you just save that, no encode, no nothing, ya just catch it and save

Think if it like some one handing you cans of soda over and over, you just put them on the table side by side... They stay as cans of soda, you could even give them to someone else, they don't really change..

Analog is more like someone runs a hose to the room and spays soda out of it.. Ya you can save it but you need a jar, a can or whatever and no mater what you do it's not going to be 100% the same nor is there any way, on the fly to all of a sudden make it "canned" soda...

I'm guessing the claims of the other card being able to convert analog to HDTV format is more about an upsample on the fly to a 16x9 sort of scale so that if one was pushing to a Plasma screen etc it would look normal.. Errr of course that is just a guess but I don't see why they would try take a analog signal and make it into some sort of 19megs a second HDtv signal.. What would that gain a person? Sep for a huge upsample or a so so signal in the first place.. Not like they can "make" more information..

HD from a tuner is already compressed. The stream is passed to the hard disk. System load is small unless you need to preview while capturing. Preview requires a display card that can handle the HD MPeg2 decode in hardware or a mighty CPU that can do it real time in software.

Some cards also include NTSC tuners. Analog capture can be uncompressed or the card may encode in hardware. Uncompressed capture requires a fast disk system or a realtime CPU encode. Hardware encode has low system load. Same goes for analog composite or S-Video input.

HD analog capture (YPbPr) is a special case and requires extreme disk speed+capacity. We are talking 20MB to 175MB per second! It is also possible to software encode HD on the fly with a very fast CPU and MJPEG or Cineform Codec.
