[linux-dvb] IR-Receiver (was Re: A LOT of newbie questions)

["Eilers, Jörg" <Joerg.Eilers@sbs.sema.de>]

Hi,

I can tell another way to do it the cheap way ;-)

Using the idea of J=F6rg Riechardt (J.Riechardt@gmx.de) for
an IR-reciver with the DVB-S card as mentioned on
Hennings page http://www.linuxdvb.tv/documentation/index.html.
This is a very easy circuit to use the internal IR-Receiver of
the card.

It really works fine for me (e.g. with vdr)!

I had difficulties in getting the BSS98, but found=20
the BS170 as an equal one.

BTW: I tried to do a "nicer" drawing of the circuit with the
"eagle" SW, but I didn't find a library with the TSOP IR-receiver...


Greetings

J=F6rg Eilers

There are several options:

1. Use the IR receiver of the DVB card. Hauppauge now ships the cards =
(at
the the satellite version) with an IR receiver and a small remote =
control
which has just enough buttons for VDR. A driver for LIRC is part of the =
DVB
driver CVS tree. The driver will only work with RC-5 compatible remote
controls. RC-5 is a common IR coding scheme used by many manufacturers. =
I
don't think there are any learing remote controls that do *not* support =
RC-5
codes.

2. Use an LIRC-compatible serial receiver. More information is =
available on
the LIRC homepage (http://www.lirc.org). Pro: you can make the receiver =
fit
exactly to your needs (i.e. build it into the PC case, use a long cable =
to
place the receiver far away from the PC). Con: you will have to do some
soldering work unless you find a company that ships a prebuilt receiver =
to
Finland.

3. Use Klaus Schmidinger's circuit
(http://www.cadsoft.de/people/kls/vdr/remote.htm) which includes a
four-digit channel display. It only works with VDR.

4. Use the IrDA port of your PC. This is probably the easiest way in =
terms
of hardware availability but the range of the IR receiver is usually =
limited
to 1-2 meters.

The CA (Conditional Access) system used in DVB systems is pretty well
designed and it's not possible to use brute force attacks to recover =
the
unscrambled stream on a PC. The CIMs cannot easily be "modified" but =
the
smartcards are the weak point of the system and content providers are =
not
consequently using the methods available to prevent abuse.

Anyway, there are problems with the current driver which prevent most =
CI
modules from working with the DVB card. So, no matter if you've got a =
hacked
card or a regular subscription, you might not be able to watch a =
crypted
program anyway ;-)
