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.
