Hi Manu,
The point here is that the frontend (demodulator + tuner) doesn't know about
the LNB drift.
Also the most important point to be noted is that LNB drift cannot be
calculated, but is measured on test criteria.
I think the misunderstanding is that lnb_drift doesn't correlate to any
Hi,
Ideally when zigzag is employed, in the end result the offset should be zero
or neglible.
In the case of the STB0899, IIRC it is rounded off. So in most cases, you
don't have an

Satellite transponders also tend to drift. Good operators will measure
the exact drift and fix their
Hi,
- Inversion might happen on up- and downconversion, depending on what
frequency situation you have.
- The SatelliteDeliverySystemDescriptor does not specify Inversion.
AFAICS, Inversion isn't a part of the transport.
Why not? It's part of it like the frequency, isn't it?

please use tasklets to do the real work for your interrupt handlers.
Take a look in the PCI drivers for an example, the pretty simple to

That looks like the same bug i have in the ttusb-nova driver, that the

Is there any better way of doing this? I've been thinking about getting
some comparators to turn the LVDS into a TTL-level eight-channel stream,
and trying to capture it with a PCI IEEE 1284 parallel port. But I'm not

port.

Exactly. Its just for optimizing performance, as well as on driver-layer

bigger chunks of data).

I'm looking for a card to receive IP over DVB to use with Linux 2.4
(probably Mandrake 9.0).
I will not need to receive any picture (MPEG or other multimedia), just
plain standards-based IP over DBV.
I'd buy a WinTV-nova (the cheap one), as it supports the delivery of the

Do you really think, this is a problem? Normally, SAT-providers state
their bandwidth in kBit/s and not MByte/s. So I believe you won't hardly
be able to exploit the bandwidth within your card with IP-Networking.
The bottelneck of SAT-IP-Networking is the shared bandwidth on the
transponder
(at least H/V) with GPIO).
it would be great if one, say, stv0299-driver would fit for all frontends
based on stv0299.
so maybe small wrapper functions, or stuff.
