[linux-dvb] Supported ATSC cards with HW mpeg encoders

[linux-dvb] Supported ATSC cards with HW mpeg encoders

[Timothy D. Lenz]

I plan to get a dual ATSC tunner at some point, but as the 2250 does not
seem to even be out yet and the HDHomeRun does not support NTSC, I am
looking at getting a cheaper card that does suport NTSC for now. I am runing
VDR and using the Nexus RGB out to a 23 year old Sony. So any HD must be
down scaled anyway. AS a couple of our Digital locals are HD, this is what I
want a card with NTSC for, to get the SDTV format of those channels. Cards
like the pcHDTV HD-5500 while claiming to suport NTSC, do not have a HW mpeg
encoder to convert the video to a format that can be sent out the Nexus
video out. You would still need to set up software encoder/decoders. Problem
is, the specs for ATSC tuner cards fall far short of providing this info. So
what I want to know is, do any of the following cards have HW mpeg2 encoders
that is suported by linux/vdr:

DVICO FusionHDTV 5 RT Lite

KWorld ATSC 115
http://www.newegg.com/Product/Product.aspx?Item=N82E16815260005 (they also
have a 120, but I'm not finding much about linix suport for it ether)

Pinnacle PCTV HD

None of the above have hardware mpeg encoders.  A good card that I'd recommend for your needs right now is the Hauppauge HVR-1800.

This is a dual tuner combo atsc/qam / hardware mpeg encoder card.  Already the ATSC/QAM support is in the 2.6.24 kernel.  Stoth has the hardware mpeg encoder working in his cx23885-video tree.  After some more testing and cleanups, it will eventually be merged into the master repository, hopefully in time for the 2.6.26 kernel release.

HTH,

Mike
