PIDs and Ports
This submenu provides all the functions that allow you to setup the PID filtering for all relevant data streams in the DVB
Transport Stream.
(PID Filtering and PID Types)
Up to 250 PID streams can be filtered by the receiver, regardless of type; however there are restrictions on how many
PIDs of a type can be assigned to a port. Aside from special types such as the NetManager2 NCC PID, there are four
types of PIDs, organized in four distinct PID Lists:
1. Net PIDs – these are the IP network data streams that are processed by the IP Stack in the receiver and
forwarded either to internal applications that use IP data, or for output on a network device such as an
Ethernet port. All data in Net PIDs are encapsulated using Multi-Protocol Encapsulation (MPE). Up to 250
PIDs can be assigned to the Net PID List, and enabled for output on the network device port(s), depending
on routing, filtering, firewall rules, etc.
If the Cyphercast option is installed in your receiver, then the ECM/EMM PID required by Cyphercast must be
assigned in the Net PID List.
The Network Control Channel PID is an MPE encapsulated Net type PID as well. However, it is a special
PID, used internally by the receiver to decode NetManager2 control commands. It is setup in the DVB
Carrier Definitions, and will not appear in the Net PID List. However, it will use one of the 250 available PID
filters, if enabled.
2. Async PIDs – these are the data streams that are available for output on the ASYNC (RS-232) port. All data
in an Async PID is encapsulated according to the DVB Asynchronous Data Streaming Format. Up to 250
PIDs can be assigned to the Async PID List, but only one PID can be enabled for output to the ASYNC port
at a time.
3. Sync PIDs – these are the data streams that are available for output on the SYNC (RS-422) port. All data in
a sync PID is RAW, a proprietary method specific to IDC MX series encapsulators. Up to 250 PIDs can be
assigned to the Sync PID List, but only one PID can be enabled for output to the SYNC port at a time.
4. Other PIDs – these are PIDs that are filtered and may be used for other applications, such as the ASI Output
option. These PIDs do not conform to any one of the types and rules above and are not routed to one of the
standard output ports.
5. MPEG over IP PIDS – these are a special category of Other PIDS which are applicable to DVB PIDS only.
This variant allows the entire content of the DVB Transport stream, or a selected number of DVB TS PIDS, to
be output through the network port(s) subject to routing, filtering and firewall rules.
When the PIDs and Ports submenu item is selected, a PID List is displayed on a page similar to Figure 2- 13 to Figure
2- 16. Generally, the Net PID List (Figure 2- 13) will be displayed by default. You can select any other PID list by
pressing one of the PID type buttons on the left of the page (i.e. one of NET PIDs, ASYNC PIDs, SYNC PIDs, Other
PIDs or MPEG over IP PIDS.).
The display fields and columns in the Net PID List (Figure 2- 13) have the following meaning:
Column/Field Description
NET port(s) enabled This is a check box, which is used to enable or disable all NET PIDs from being demultiplexed
by the receiver.
Radio Buttons Clicking on the radio button will select a PID in the list. Once selected, you can use the Edit
Selected button to edit the PID definition, or Delete Selected to delete the PID from the list.
Only one PID can be selected at a time.
NOTE:
Up to 250 PID
streams can be
filtered by the
receiver,
regardless of
type; however,
there are
restrictions on
how many PIDs
of a type can be
assigned to a
port.
Whenever a
PID is inserted
into a PID list, it
will use one PID
filter in the
receiver,
whether that
PID is enabled
for output or
not.
