Because of its software based architecture,<br /> many typical DAB services can be generated and multiplexed on a single<br /> PC platform with live or pre-recorded sources.<br /> <br /> A DAB multiplex configuration is composed of one ensemble. An ensemble<br /> is the entity that receivers tune to and process. An ensemble contains<br /> several services. A service is the listener-selectable output. Each<br /> service contains one mandatory service component which is called pri-<br /> mary component. An audio primary component define a program service<br /> while a data primary component define a data service. Service can con-<br /> tain additional components which are called secondary components. Maxi-<br /> mum total number of components is 12 for program services and 11 for<br /> data services. A service component is a link to one subchannel (of Fast<br /> Information Data Channel). A subchannel is the physical space used<br /> within the common interleaved frame.<br /> <br /> __________________________________________________<br /> | CRC-Ensemble | ENSEMBLE<br /> |__________________________________________________|<br /> | | |<br /> | | |<br /> _______V______ _______V______ _______V______<br /> | CRC-Service1 | | CRC-Service2 | | CRC-Service3 | SERVICES<br /> |______________| |______________| |______________|<br /> | | | | |______ |<br /> | | | | | |<br /> __V__ __V__ __V__ __V__ __V__ __V__<br /> | SC1 | | SC2 | | SC3 | | SC4 | | SC5 | | SC6 | SERVICE<br /> |_____| |_____| |_____| |_____| |_____| |_____| COMPONENTS<br /> | | _____| | | ____|<br /> | | | | | |<br /> __V________V__V______________V________V___V_______ COMMON<br /> | SubCh1 | SubCh9 | ... | SubCh3 | SubCh60 | ... | INTERLEAVED<br /> |________|________|_______|________|_________|_____| FRAME<br /> Figure 1: An example of a DAB multiplex configuration<br /> <br /> GENERAL OPTIONS<br /> -h : get this help<br /> -m : DAB mode (default: 2)<br /> -n nbFrames : number of frames to produce<br /> -o : turn on TCP log on port 12222<br /> -V : print version information and exit<br /> -z : write SCCA field for Factum ETI analyzer<br /> <br /> INPUT OPTIONS<br /> -A : set audio service<br /> -A : set CRC-Bridge data service<br /> -D : set data service<br /> -E : set enhanced packet service<br /> -F : set DAB+ service<br /> -M : set DMB service<br /> -P : set packet service<br /> -T : set test service<br /> inputName&lt;n&gt; : name of file for audio and packet service and Udp input address for data service ([address]:port)<br /> -a : packet address (default: 0x200 (512))<br /> -b bitrate&lt;n&gt; : bitrate (in kbits/s) of the subchannel (default: audio 1st frame, data 384, packet 32)<br /> -d : turn on datagroups in packet mode<br /> -f figType : user application type in FIG 0/13 for packet mode<br /> -g language : Primary service component language: english=9, french=15<br /> -i id&lt;n&gt; : service|subchannel|serviceComponent id &lt;n&gt; (default: &lt;n&gt;)<br /> -k : set non-blocking file input (audio and packet only)<br /> -L label&lt;n&gt; : label of service &lt;n&gt; (default: CRC-Audio&lt;n&gt;)<br /> -l sLabel&lt;n&gt; : short label flag of service &lt;n&gt; (default: 0xf040)<br /> -p protection&lt;n&gt; : protection level (default: 3)<br /> -t type : audio/data service component type (default: 0)<br /> audio: foreground=0, background=1, multi-channel=2<br /> data: unspecified=0, TMC=1, EWS=2, ITTS=3, paging=4, TDC=5, IP=59, MOT=60, proprietary=61<br /> -y PTy : Primary service component program type international code<br /> <br /> OUTPUT OPTIONS<br /> -O output : name of the output in format scheme://[address][:port][/name]<br /> where scheme is (raw|udp|tcp|file|fifo|simul)</div>
