[linux-dvb] DVB-S Stream multiple Channels

[Nikos Parastatidis]

Hi there

i would like to ask you if it is posible to stream multiple channels
with any DVB-S card in linux.

do DVB-S have the capability to decode/tune to multiple channels?

i know this is not posible at DVB-T because of the tuner, it cannot
tune to multiple channels at once, you need dual or more pci cards to
do this.

what about at DVB-S ?


Thanks in advace

Nikos, if they are on the same transponder/multiplex you can stream
multiple channels. If not you need a different tuner per channel.

i see !
this creared everything now
so DVB-S has a tuner also

i thoght it was one frequency for every LNB and every satelite
and with this frequency was a carrier for all channels.

anyway ok in theory
but are there frequencies that cary more than one channel?
can someone give me an excample like Patrick gave me on DVB-T
if you can speak Greek :-) and give me a nova excample it would be great :-)

how can i check it my self within dreambox ?
how can i check if one freq has many channels?

Thanks in advance
your help so far was very precius.

You can check you channels.conf file: you have the channel name first 
then the frequency (and I think the channels are oredered by 
frequencies, though I can be wrong here).

To see what channels are available, I have always found sites like 
www.satcodx.com and www.lygsat.com useful to see what is available on 
individual satellites/transponders.

As the other respondents have stated, it *is* possible with DVB-T and
DVB-S (and I guess probably possible with any other multiplexed format
that is not PID-filtered).

You should be able to tune to and record from other channels on the
same multiplex if your software allows. This is a key new feature of
the soon-to-be-released 0.21 version on MythTV.
