DVBT 2 (114 Viewers)

[Mew]

I agree it is a bit ambiguous but I would read,

"The world’s smallest (dual DVB-T/T2) half height card design enables this product to grace even the smallest and sleekest entertainment PC’s."

to mean two DVB-T/T2 tuners.

I believe my Hauppauge HVR-4000s and HVR-4400 have been advertised as having a DVB-S/S2 tuner but it is just one satellite tuner on the card capable of both DVB-S and DVB-S2. I guess you have to say both otherwise people would query if you could receive DVB-T with a DVB-T2 card (and it also sounds like you are offering more!)

just why did they bother with the DVB-C tuner

Why not? There aren't that many DVB-C tuners around - and I need one (preferably a dual one) to replace floppy & twinhan combo (both are not optimal).

Just not many (if any) DVB-C users in the UK (only seen that Sweden has started this month). Just as it is going to be the first T2 card to market it would make sense to just be DVB-T2 and cheaper and release a separate cheaper DVB-C card

Just not sure how many people would want both T2 and C?

I could use both It might not be that costy to have a tuner that is capable for both DVB-C / DVB-T(2). So it might be much cheaper for them to produce only one kind of card than two separate (almost identical cards).

Adding DVB-C is not a problem if all DVB-T bands are covered. Sometimes manufacturers only covers band IV and V with there DVB-T cards (470 to 854MHz), but if Band I (47 to 68MHz) and/or Band III (174 to 230MHz) is covered then the DVB-C band is in between. And yes there are lower frequencys but I don´t think they are so common(?).

I think that Band III will be more common in Europe for DVB-T, this is because mobile networks (4G/LTE) will use some of the highest channels in Band IV and more space is needed.

There is also different modulation etc. used in the signal itself, so it wont be only the bandwidth difference that needs to be supported.

 

[tompa]

Yeah some small differences, but thats only SW

I would assume the demodulation etc. are done on the HW itself, not in the driver.

 

[tompa]

Yeah, the demodulation its separate (and its HW) but its still controlled by SW in an so called IQ-demodulator. Then you have to interpretation the data off course, and there could be some differences...?

A while ago, I sent BlackGold an email asking them to clarifying the spec of the BGT3620, pointing out the ambiguity of their web-site.

And also asking them to indicate when the BGT3620 would ship. (December the 32nd is no use to me!)

Unfortunatley they've chosen not to reply to my politely worded enquiry.

You really have to wonder why...

I'm thinking it can't be good news.

Brian, there's alway this instead: PCTV systems nanoStick T2 290e DVB-T2 (23076) - dabs.com

Quite tempted myself, just would prefer a pci-e card ideally...
