Description
===========
ODR-DabMux is a software multiplexer that generates an ETI stream from audio
and data streams. Because of its software based architecture, many typical DAB
services can be generated and multiplexed on a single PC platform with live or
pre-recorded sources.

A DAB multiplex configuration is composed of one ensemble. An ensemble is the
entity that receivers tune to and process. An ensemble contains several
services. A service is the listener-selectable output. Each service contains
one mandatory service component which is called primary component. An audio
primary component define a program service while a data primary component
define a data service. Service can contain additional components which are
called secondary components. Maximum total number of components is 12 for
program services and 11 for data services. A service component is a link to one
subchannel (or Fast Information Data Channel). A subchannel is the physical
space used within the common interleaved frame.

Files in this folder
====================
The configuration is given in a file, this folder contains examples.

A basic example is in the file *example.mux*, a more complete view of the
settings is available in *advanced.mux* and configuration settings related to
service linking are shown in *servicelinking.mux*

An explanation on how to use the remote control is in *remote_control.txt*, and
*zmq_remote.py* illustrates how to control ODR-DabMux using the ZMQ remote
control interface.

Two scripts are used for monitoring systems: *stats_dabmux_munin.py* for Munin,
and *retodrs.pl* for Xymon. You can use *show_dabmux_stats.py* to print the
statistics to console.

*DabMux.1* is an old manpage that describes the command line options that
existed in past versions. It is kept for archive.
