NVIDIA's new MCE device places two TV tuners on a single card

NVIDIA has launched the ultimate tool for Media Center Edition (MCE) PC owners. The NVIDIA DualTV, as its name implies, offers two tuners on a single card.

By having two separate tuners onboard, the DualTV tuner is able to record two shows at once or allow you to record one show while you watch another. And since the DualTV tuner is a full-fledged MCE device, you can transfer recorded material to a personal media players or portable game players. Live or recorded shows can also be streamed throughout the home to game consoles or Media Center Extenders courtesy of software from Orb Networks.

Other features of the NVIDIA DualTV tuner include:

  • MediaSqueeze compression technology
  • PureVideo technology
  • 3D comb filter
  • 3D noise reduction hardware
  • In-line TV amplifier.
  • Multi-stream hardware encoder

Scott Vouri, general manager of multimedia at NVIDIA adds:

"There are other TV tuners in the market today, but the NVIDIA DualTV tuner offers some key differentiators that make it stand out. Based on our internal testing it’s measurably the best picture quality of any dual tuner card and saves disk space. It’s easy to use and install, and is designed for people who want to watch what they want, where they want, whenever they want."

The NVIDIA DualTV tuner is available now for a suggested retail price of $169. You can also purchase the DualTV tuner with a remote and receiver kit for $219.

1920pixels x 1080pixels x 30fps = 62208000 times 24bit colordepth = 1,492,992,000 bps divided by 8 = 186,624,000 Bytes P/S.
But that's NOT variable since this is raw pixels uncompressed.
So 250MB is enough.

And yes, as you say, if you hardware compress it even 133MB should do it too, but of course the PCI system is shared resources so that assumes you have no soundcard or networkcard (nor onboard on the pci subsystem) nor RAID (onboard on pci) running.
Still mpeg compresses enogh to be way below 133MB, so theoretically even PCI could support it, although pci-e is much more suited and logical of course.

I wonder if it would be possible for them to take advantage of the installed video cards to do the compressions. Suppose you had a pair of 7900 GTX video cards in SLI. That's a lot of processing power right there. It seems like you could take the raw HD stream in from a separate card, since I don't think many graphics cards have a coax connector. Then let the video cards handle the compression to MPEG4 or whatever format. What format does HD content come in as by default anyway? Is it MPEG2?

But the problem is to do that, you have to transmit that uncompressed data to the video card...and if your tuner card is on the PCI bus, you don't have the bandwidth to send it anywhere in that state.
