I've been trying to minimize energy consumption and noise on my vdr system.
One of the most important factors apart from a hardware pid filter seems to
be the usb buffer size. I've collected some data about that on my wiki user
page: http://www.linuxtv.org/wiki/index.php/User:Hlangos
Greping through the sources I've seen that the dib0700 driver uses a HUGE
usb buffer of 39480 bytes. This looks very promising. But before running
out in the street and buying the first dib0700 device I'd like to know if
there are any devices that are
- especially good (sensitive reception, fast switch time, sensible tuner
data (usable for comparing different antennas) and so on)
or
- especially bad (invers of the above plus hardware bugs, annoyances and so
on..)
any feedback is appreciated.
cheers

PS: A "full" remote (not one of those pesky credit card sized things that get
eaten by the hoover) would be a plus.

Hi Henrik,
one of the cards in my system is the dib0700 based "'Hauppauge Nova-T 500".
Compared with the "TerraTec Cinergy 1400" I would say that the receiver
sensitivity is worse but the main problem I have is that the card
consumes a loot of energy (8-13W), which is much more than the
Terratec(5-6W).
I calculated this using measure values of the whole system captured with
a Conrad/Voltcraft Energy Monitor 3000.
Personally I am little bit shocked about that and wondering if this can
be true because the dib is a USB-device, but the Voltcraft is one of the
better measurement device.
Maybe the VIA usb-hub controller on the board is the problem?!
Would be interesting of someone has the same or other experiences with
this card or other PCI based cards. Hauppauge ignores all my questions,
so I can't recomment products of this manufacturer anyway.
Greetings,
Marco

That's a little bit weird USB itself should provide max 5V 500mA which would be
2.5 Watt; if it requires more then the device has to be self powered.
Maybe you can try to use a different USB device (eg. storage) just for
testing the
consumption. USB is supposed to require alot power (the controller).
You might try to unload the ehci/ohci driver too.

Hi Markus,
it seams that you don't know what the Hauppauge Nova-T 500 is:
Its not a USB device itself, its a PCI card with a VIA PCI/USB-Bridge
Chip connected to multiple DIBcom USB chips:
http://www.bttv-gallery.de/high/bttv-gallery.html
I bought the card with the idea in mind that it uses low power USB
technology, but that was a mistake.
Next time I will buy a real usb device and know it isn't allowed to eat
more than 2.5W.
Greetings,
Marco

I agree, it is wierd, there is a lot of hardware out there that strains the
usb power supply way beyond the secified 500mA but that alone can't explain
the 8-13 Watt.
My guess is, that the rest of your system uses more energy because it has to
deal with a USB device instead of a PCI device. There is different hardware
involved that otherwise might not be powered at all and there's the whole USB
protocol stack that is involved and possibly a usb hid device (the remote) that
has to be polled x times per second. Don't let a name like "interrupt transfer
mode" fool you. USB transfers are always initiated by the host, so it has to
poll input devices a lot.
How exactly did you measure the power usage?
Did you run the same software to test it? ("zap" uses way less energy than "vdr")
The same channel? (Different bitrates even within the same channel can have
some effects)
I tried to minimize the effects of the software by making sure that an idle
system with the hardware installed has the same cpu load and
wakups-per-second as the system without that hardware. But it admit i didn't
measure power usage directly. Since I am only dealing with usb devices, I could
run the usb pin 1 through an amp meter...

Yeap, thats the way to go.
And try running powertop to see if your cpu does any extra work even when
it should be idle.

Does it deal well with switched-mode power supplies? Those things tend to
confuse power measuring devices unless they have a good active PCF.

I try to avoid, when ever possible, to participate in such statements.
I don't even posses currently and never did previously any Hauppauge
device.
That you may end up in some m$ support only ring in somewhere on the
planet is also very likely too, but we also had very different results
in the past even for that.
In fact, Hauppauge's GNU/Linux support, let's say during the last five
years, is such outstanding well, that it is not even worth to try to
start counting, who other OEM can even come close to it.
On the higher level, chip manufacturers, we also had very good support
from Philips/NXP.
What you likely don't see is, that people who did this, did it still in
their unpaid and limited free time, but m$ driver only colleagues at
work might have helped as well sometimes.
And there is still a huge market for v4l-dvb related devices going over
the whole globe, it still increases like mad. It is a, count up
yourself, N $ market each year.
Since a lot of fish is springing out of the water, because of that, we
have this NDA problem.
So, if you would like to have an argument on this issue, you should be
able to count who has contributed _despite_ of that and you don't know.
Cheers,
Hermann

Good to hear that the support on the backend is much better than on the
early years of DVB+Linux.
Anyway as a customer I can't recommended products of a manufacturer if
the customer "support" complete ignores any questions, and I don't asked
something about linux.
But of course I am currently unable to appoint any company with good
customer support, so maybe it doesn't make sense to use such a criteria
if you want to buy something...

Did you take a look at the Terratec remotes? They look quite good to me,too
with color buttons and so on.. It looks a little cheaper than the
HAuppauge's remote but hopefully that's just due to the choice of colors..
Even the XXS seems to come with the full 48 buttons remote.

I do live close to the radio tower but some receivers have problem with some
channels when using a stick antenna. Thats why I switched to a cheapo do it
yourself double quad. Here's the link to the instructions in German:

Thats wierd. So the usb controler on the Nova-TD and the host controler on
the SB700 are incompatible?

Is there a way to truely compare different receiver's quality? The
information that femon and tzap report (SNR, BER, UNC) are only what the
receiver itself says.

I really like that kind of input.
Especially for the follow up version, with dedicated antennas for each
transponder frequency.
I do confirm, that it has the potential to replace two amplifiers, one
external and one on the card under bad reception conditions, not to talk
about the antenna itself and about what all that might cost else
installed by an expert on light-speed coming into your home ...

Not yet and hard to come by, also lots of different antennas and
amplification.

I tried a few different USB tuners with a SB700 based motherboard
until I found out the drivers where not up to scratch for the USB on
the SB700 and caused a lot of "dvb-usb: bulk message failed"

does somebody know if the problem is still there even with this print
ehci_hcd 0000:00:12.2: applying AMD SB600/SB700 USB freeze workaround
ehci_hcd 0000:00:13.2: applying AMD SB600/SB700 USB freeze workaround
visible in dmesg caused by this patch?
