[linux-dvb] DVB support for alevt

[Thomas Sailer <t.sailer@alumni.ethz.ch>]

The following patch adds DVB support to alevt:
http://www.baycom.org/~tom/alevt-dvb.patch

Patched RPMs from RedHat's 7.1 powertools CD are on:
http://www.baycom.org/~tom/alevt-1.6.0-3jnx.i386.rpm
http://www.baycom.org/~tom/alevt-1.6.0-3jnx.src.rpm

Usage:
alevt -vbi /dev/ost/dvr0
starts decoding the first program in the PAT having
a teletext stream.
alevt -vbi /dev/ost/dvr0 -pid 0x67
starts decoding transport stream PID 0x67
alevt -vbi /dev/ost/dvr0 -progname SAT.1
starts decoding the named program's teletext stream

Note that the first and third option require a fairly
long startup time. In that case, alevt first has to
parse several tables, namely PAT, SDT and for each
program listed in the PAT the corresponding PMT. It
does this sequentially. Esp.  the SDT seems to
have fairly long repetition periods (~5s) so startup
may take 10s.

As with bttv, an external application must be used
to do the tuning, eg. tuxzap or vdr.
