Technisat Skystar 2 = HDTV?

Postby GrahamGo » Wed May 27, 2009 10:01 pm

I have read in a few places that the Skystar 2 with the right drivers can receive HDTV. Is this right or have the authors meant to refer to the HD version of the card?

DVB-s cards don't even know what's inside digital stream (SD or HD; mpeg2, mpeg4, or mpeg6).
They simply pass entire transport stream to the host PC.

thus, any card can receive HDTV (including skystar 2).

So you mean I can receive HD channels via DVDream also with my "regular" Creatix/CTX DVB-S/T card (when I have a correct H.264 decoder like the Cyberlink or Elecard)?

Ok, so you don't need an DVB-S2 card then? Are there many HD channels in DVB-S1?

It all depends on what is transmitted by satellites which you can see.
Since I'm on other side of the globe, I can not tell much about what you can get with DVB-s card.

Surely, with DVB-S2 card you can get more channels (DVB-S2 can tune to everything DVB-s does, plus some more).
Keep in mind, neither DVB-s nor DVB-S2 cards do audio/video decoding.
They don't care about SD or HD. They care about signal modulation only (and they pass transport stream to PC).
The rest is done by your CPU/GPU and codecs.

Ok, thx!

So the difference between S and S2 is only channels/frequencies. I will test with some HD channels I can receive here.

Thanks for this too! I am on your side of the world. I am interested in 119W DN have you any experience of this bird?

DN does not use DVB-S2 at all.
Thus, using DVB-S2 card you'll get exactly the same amount of channels/transponders as with 10 year old plain DVB-s card.
Cause your DVB-S2 card would work in DVB-s mode only.

With very small exception (one or two TPs on sat 72.7W), DN placed all HD channels on transponders which use Turbo-coded FEC (either QPSK or 8PSK).
Turbo-coded FEC is not the part of DVB-S2 standard, thus DVB-S2 card can not be used to tune to these transponders.
And for sure, your SkyStar 2 can not tune to Turbo-coded transponders either.

Btw, besides couple of spot-beams (which you may not even see) there are no HD channels on 119.00 sat. Thus, you are not missing much (if any).
