TV Cards

chio · Post by **chio** » Thu Apr 14, 2005 11:44 pm

Hi all, has anyone written any apps to access TV cards? Such as ATI All-in-wonder (AIW).

I want to make or modify an app that can change my TV channels and work like a TV tuner. Also if it can decode the video signal from the cable company. I don't mean steal it, I pay for cable, but when I veiw it through my PC I only get the standard channels.

I know that AVICAP did something with TV but can't find it anywhere.

Thanks,
Chio

I believe that windows has a API for this stuff, which should work as long as the proper drivers are installed.

There may be a few opensource ones out there!

I think that what you "see" is the analog signals.
In my living room I got a Digital cable box,
in my work room I don't, and can only get a handfull analog channels.
You'll need a Digital Broadcast/DTV/HDTV/whatever card most likely.

i'm wondering how to...
i find in msdn that it could be done thanks DirectShow.

there's are two Interfaces you have to use :

tuner.IAMTUNER
tuner\QueryInterface(a,b)

tvtuner.IAMTVTUNER
tvtuner\QueryInterface(a,b)

here is some docs http://msdn.microsoft.com/library/defau ... hannel.asp

can someone can try to use this interface in purebasic ?
i don't know how to make it works by myself.

Is it possible to have digital tv working with Purebasic ?
All the apps compatible with my card (hauppauge nova-t) are big bloated stuffs, maybe a little Purebasic app could help

?
