BOARD PLUG-IN ek-dma/4

“ASI transparent

demultiplexer”

The EK-DMA/4 board is an ASI to 4 ASI transparent
demultiplexer (see EK-DMA/4 block scheme) and it is
composed by two physical inputs, represented by the Features
two input BNC connectors located in the board panel,
plus one internal input that is directly connected with  4+2 different ASI output
the EK-MFR/2 between the internal connection matrix
 Complete web
line (located in the EK-MFR/2). management
The three inputs are connected to a selector controlled
by the SEL IN parameter. By the menu it is possible to Applications
change the value of the SEL IN parameter to decide
which input signal must be processed by the board. If  Digital Microwave Links

the “AUTO” value is load on the SEL IN sub-menu the  DTV, DVB-T, DVB-S
system automatically switch on the first valid transport  Management of several ASI
stream input in according to the priority: IN1, IN2, INT signals
IN.
The selected input transport stream is sent to the packet
selector module that filters out all the packets except
those with the selected DATA PID. The transport

stream is then sent to the VC demapper in order to send
any different virtual channels (VC1-VC8) to a different
selected outputs.
The outputs of the EK-DMA/4 are six, four physical,
represented by the four BNC located in the board panel
(see EK-DMA/4 board panel) plus two internal directly

connected to the EK-MFR/2 by the internal connection
matrix line (located in the EK-MFR/2). For a correct
functioning the EK-DMA/4 board must be utilized in
relation with EK-MPA/4 board.
