Is it Possible to Take advantage of TV's decoder?

[David.A.Martin]

Is it possible to use my computer with GBPVR and an HDTV Tuner card, to record over the air digital signals (ATSC) then simply pump those signals (not a decoded picture) back to my HDTV to take advantage of the TV's decoder?

I have an older computer and I'm thinking if it only takes a small bit of the CPU to record a signal, couldn't I use an equally small amount of the CPU to pump that signal back out through some sort of TV out card, that isn't decoding the picture but just pumping the signal out to the TV for it to decode?

Then my computer would simply be the recorder and signal playback mechanism. I'm not sure what kind of "RF Signal Video Out" video card that would be or if that is possible. I've got a great new HDTV and an old computer. Hoping I can take advantage of both.

Thanks

Sorry, no thats not possible.

If you have a strong signal, you can just use a splitter and send one to the TV and the other to the computer

That doesnt give him what he's looking for though. He's hoping to have GB-PVR generate ATSC signals and have the TV decode it, rather than using a decoder on the PC and sending video to the TV.

i should read more carefully

You need a system that handles transport stream. Far as I know GBPVR doesn't.

There is much more to it than that. (BTW, GB-PVR can record/play transport streams)

There expensive multi-PCI card solutions or rackmount solutions that can encode/modulate ATSC signals, but they're not practical for any consumer application like this, and are only usable from the specialist software that comes with these devices. (think thousands of $$$ for these devices)

Acually I meant a tuner card that can output TS to a TV that can accept TS.
I don't know of a TV that accepts TS, but I have heard manufacturers claiming that was coming. My comment about GBPVR was that I didn't think you enabled any tuner cards to output TS. Reencoding ATSC from TS and broadcasting it, would cost $$$'s like you said, but that may be the only way to the MPEG decoder in a set.

in the mux list you'll see a .TS output mux type...
i think it requires hdtvpump or something similar to work, but may not..
so GBPVR is ready..
now 'sending' that to a tv would require some software bits tho..
[what kind of connection? tcp?]

Remember there is quite a difference between recording a transport stream and producing a modulated ATSC compliant bitstream (COFDM or QAM256). You need specialist hardware to do that.
