FILTERING functions

Packet Identification (PID) filtering can be used in an MFN network to reduce the
bit rate of an incoming TS in order to accommodate it to the useful bit rate that the
modulator can handle in a particular DVB-T set-up.
Every Program Elementary Stream (PES) carrying video, audio or data contained
in a TS multiplex is identified by a unique PID. The MO-16X allows the user to eliminate
up to 16 PES's from the TS. Note that the MPEG-2 TS is not really re-multiplexed
because the system information tables are not updated, only the PES's are dropped to
help reduce the bit rate. This feature finds its application in, for example,
trans-modulating a high-bit-rate DVB-S or DVB-C signal to DVB-T.
Mode
Select ON to enable PID filtering and OFF to disable it.
PID 01 — 16
Up to 16 PIDs can be discarded from the input transport streams. Note that the
PID search applies to both the HP and LP inputs. The valid range of decimal values is
1 to 8191. PID 0 is reserved for the Program Association Table (PAT) and cannot be
eliminated.
