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 NetManager NCC PID, there are four types of PIDs, as organized by 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. This can be done
either directly here, under PIDs and Ports, or in the Cyphercast configuration page.
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 NetManager
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 using MPE as
well. 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 encapsulated using 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.
When the PIDs and Ports submenu item is selected, a PID List is displayed on a page
similar to Figures 4-10 to 4-13. Generally, the Net PID List (Figure 4-10) 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, and Other PIDs).
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.
