Update Firmware - Fracarro D-Matrix 4S Instructions D'emploi

5.6 UPDATE FIRMWARE

From the menu OPERATIONS -> UPDATE FIRMWARE -> UPDATE FIRMWARE you can check
which firmware release is installed and then update the system if required.
To update the system, check there is correct update package available in a PC folder, then
select it and press on BROWSE and then UPDATE MODULES. Wait for the operation to finish.
5.7 RESTART MODULES
From the menu OPERATIONS -> RESTART the system restart can be requested.
6. PROGRAMMING INDICATIONS
INTRODUCTION: before programming the D-Matrix, the following general indications should
be followed.
Decide whether you want to use the ALL PID OUT function or to program the programs singularly
(PID) that must be available in output.
With the ALL PID function, the transport stream received from the specified input is rebroadcast
at the output with no further processing.
Therefore the output channels need no management, and all the contents, including non-
standard or erroneous, in the original transport will be rebroadcast without change, ensuring
compatibility with other more "rigid" decoders in managing the input data. However, at the same
time the programs or priorities cannot be managed in the case of band limit problems.
If the output band is insufficient, due to the lack of priority management, EACH program in the
transport could lose packages, meaning only artefacts are view on the TV. The ALL PID mode
therefore should only be used when the output band is definitely the same or higher than the
input band. If the programs are programmed singularly (PID) for them to be available on output
the indications given below must be scrupulously followed.
Given the overall bitrate of an output mux, determined according to the standard and modulation
parameters set, the overall band for the associated programs must be much lower, otherwise
the low priority programs will be lost or malfunction.
After configuring the output mux parameters, the available band can be viewed in the web
configuration homepage or from the panel menu in the section OUTPUT → MUX1 / MUX2 →
BITRATE. Programs can then be added to the output mux until the overall peak band for the
added channels exceeds the mux band, as the excess band data that cannot be broadcast are
rejected by the system.
Therefore, the installer must check that the peak band for the input programs does not exceed
the available band.
If the band limit is exceeded, and for as long as this occurs, the system automatically chooses
which programs to broadcast according to the priority order, guaranteeing correct broadcasting
for the low number (high priority) programs.
The first programs that are penalised are the high number (low priority) ones, which lose
packages and are viewed with errors.
If the output band falls lower than the available band, all the programs can be broadcast without
any data being lost.
To aid this, the system offers a band graphic indicator, in the web management, which is updated
automatically every second.
