The LNB remote power supply is able to supply a maximum current of 400 mA, total for all the inputs. If this limit is exceeded, a current limiter
triggers, which temporarily deactivates the remote power feed on all the inputs, reactivating them one at a time, until the input (or inputs)
causing the problem is identified. The remote power feed and reception from these inputs is finally deactivated, while the loop function remains
active. The red led then lights up corresponding to the overloaded input. Reception from the error inputs can be reset after solving the system
malfunction, deactivating and reactivating the input, or by restarting the D-Matrix 4S EVO. The signal received from the sat inputs can be
decrypted using a maximum of two CAM modules, inserted in the slots on the right. Each slot can be programmed in two ways:
1. It can be associated to one (and only one) of the inputs: the CAM will decrypt the wanted programs from the selected input and the signal
received by the same input but with different codes could also be decrypted, associating two CAMs to the same input.
2. It can be associated to a personalized transport stream (FLEX): the CAM wll decrypt the programs coming from different inputs.
The product enables reproducing a program saved on files with standard transport stream format (.TS files). This file can be generated beginning
with any audio/video file, by using a specific conversion tool. The file must be in a USB storage unit connected to the device, formatted with
FAT32 file system.
Programs from satellites or file can be intelligently multiplexed, which means the user is able to generate ad hoc output MUX, depending on the
available bitrate and the end user’s preference. The system automatically regenerates the transport stream, also using certain position/priority
parameters, so that certain programs are preferred over others that are considered less important in bitrate terms.
For example, consider a MUX generated from the P2, P2 and P3 programs received from a satellite, configured with the respective positions 1,
2 and 3 (the lower position means the higher priority). If the overall bitrate of the three programs is lower than the available amount from the
output modulation, all three programs are produced in output without any bitrate loss. However, supposing the total bitrate exceeds the available
amount in certain moments, the system guarantees viewing of the higher priority programs, cutting the bitrates of the lower priority ones.
Therefore in this case, program P3 will be degraded (squaring), while the P1 and P2 programs are not changed at all.
In certain situations, the installation requires that a transport stream received from a satellite is not multiplexed but directly transmitted without
any processing. For this the ALL-PID mode can be activated, and in this mode all processing on the transport stream is deactivated.
The output transport-streams are modulated according to the DVB-C or DVB-T standards. The modulation parameters are available through the
configuration interface, and are also independent for the four MUX, except for the standard used (DVB-T or DVB-C) which must be the same for
all MUX and the output channel which can be set as described before.
The unit can be managed by the web interface. Equipped with an Ethernet network interface 10/100 which allows the direct connection to a PC
(by a crossed cable) or a LAN network.
