Hauppauge 4400 and double DVB-T tuner mode

[sl91]

Hi everybody

 

I have installed a Hauppauge HVR PCIe 4400 card in my computer. I would like to use it only in the DBV-T mode. How to make DVBViewer understands that this card is capable of two independant channels (i.e. two tuners) ? For instance, DVBViewer see one 885BDA (DVB-T ?) and another 885 alt BDA (DVB-S2 ? useless in my case). I would like to be able to record two channels on two different transponders at the same time.

 

Thanks

AFAIK it is not possible to use the HVR 4400 DVB-S tuner for DVB-T. If the DVB-S tuner could be configured for DVB-T (and the other way round) there would be two pairs of tuner entries in DVBViewer, each pair representing a DVB-S/T hybrid tuner.

Longer answer:

DVB-S is 950MHz to 2100MHz IF with 13V/18V and 22kHz on/off on cable. Modulation is QPSK, or on DVB-S2 it's APSK also

DVB-T is 50MHz to 870MHz or 470MHz to 870MHz and COFDM modulation. Each 7MHz or 8MHz has 1,600+ or 6,700 separate QAM16 or QAM64 carriers (DVB-T2 has even more).

Any "hybrid" is usually two physical tuners on one connector. Better having both separate like HVR PCIe 4400 card. Maybe someday you will add a Dish and LNB for the DVB-S part.

About 10 Euro buys a USB DTT stick. Or less than 30 Euro a dual DTT stick. Add a cheap USB stick and TV cable splitter(optionally distribution amp if signal too low) and then you have two tuners for DTT.
