dvbsnoop is a DVB / MPEG stream analyzer program,
which enables you to watch (live) stream information in human readable
form.
Its purpose is to debug, dump or view digital stream information
(e.g. digital television broadcasts) send via satellite, cable or terrestrial.
Streams can be SI, PES or TS. Basically you can describe dvbsnoop as a "swiss
army knife" analyzing program for DVB, MHP,
DSM-CC or MPEG - similar to TCP network sniffer programs like the old and
famous snoop on Sun Solaris or tcpdump on Linux (which is in fact
a kind of a clone of SunOS 'snoop'). You may also analyze offline mpeg streams,
e.g. stored on DVD or mpeg2 movie files.
dvbsnoop is a command line
based program. It's text output can be used to for postprocessing via scripts
or graphical analysis software like MRTG or gnu-plot.

dvbsnoop is helpful for people interrested in DVB
and/or in the technical part of digital television (e.g. if you are a developer
of DVB related software). If you are in need to sniff data streams (e.g.
tcp/ip, multicasts) send over cable (DVB-C), satellite (DVB-S,
DVB-S2) or terrestric (DVB-T, DVB-H), dvbsnoop also offers
some features and protocol decoding.
In the beginning dvbsnoop was
mainly written to learn and understand the DVB protocol structures and streams
sent via satellites. Have a look on the feature
list, what dvbsnoop is capable of and what it can do for
you...
Dvbsnoop is still under development. Ideas, bug reports,
enhancements are welcome. Dvbsnoop is currently part of the
tuxbox project and is designed to run on
unix based set top boxes.
