[linux-dvb] problems with remote control of dvb-s

[Matthias Hilbig <hilbig@upb.de>]

there are two big problems with the remote control of the hauppauge dvb-s 
at the moment:

1. after an ARM Reset the remote control stops working in vdr:

I turned debugging on, and saw that after an arm crash the lirc_dvb and 
lirc_dev module continue work i.e. you see
"ircommand = xx" on the screen and irw works flawless
but somehow vdr stops reacting to ir commands and shows sometimes a mix 
between recording and actual tv program...

by the way its very easy to crash the arm:
watch a recording
press ok to display status bar
press yellow and green in random order until arm crashes :-)
(used vdr-1.0.0pre3 and driver 0.9.4)

2. the remote control doesnt recognize different systems (TV,VCR, SAT...)

A text i found in the web says:
"The RC5 code is a 14-bit word bi-phase coded signal. The two first bits 
are start bits, always having the value 1. The next bit is a control bit or 
toggle bit, which is inverted every time a button is pressed on the remote 
control transmitter. Five systems bits hold the system address so that only 
the right system responds to the code. Usually, TV sets have the system 
address 0, VCRs the address 5 and so on. The command sequence is six bits 
long, allowing up to 64 different commands per address."

driver developers: is it possible to decode these system bits in the driver 
and not in the firmware? So you could specify that lirc_dvb should only 
react to VCR commands...

gruss
Matthias
