Figure 17. Streaming settings table
This table is used to see detailed service information and select individual streams for descrambling.
The following service information is shown in the table: service title, service provider, service id, PMT PID, types and
PID-s of service streams, PCR PID. After checking the "Descramble" checkbox of service line, all streams of this service
are included in a descrambling list of the CA module. Unnecessary streams can be deselected from the descrambling list by
unchecking corresponding "Descramble" checkboxes of streams. Close the table by clicking on the
icon.
Modules with ASI output (sda410C, sta410C, saa410C) support BISS descrambling function. Descrambled services
available on IP and ASI outputs. BISS code for service scrambled with this scrambling system can be entered in the detailed
service information table (Figure 16).

Enter the BISS code in hex format to "BISS code" box and press the "Update" button.
7.4. Output settings
This screen consists of three tables: "Streaming settings", "SAP/SDP settings" and "Output streams". The "Streaming
settings" table is used specify common streaming parameters to all output streams. The "SAP/SDP settings" table is used to
configure the announcement and service description SAP/SDP channel. The "Output streams" table is used to individually
configure the output streams.
7.4.1. Streaming settings table
This table is used specify common streaming parameters to all output streams.
This table consists of following lines:
"Protocol" - the drop down menu offers two options: UDP and RTP/UDP.
UDP is a transport protocol which is not connection oriented and is particularly
useful for streaming. RTP/UDP adds extra data fields so that the data flow is
served at the correct speed for its projection in real time.
"TS packet count" - count of the MPEG2 TS packets in the UDP packet.
Can be selected from one to seven. It is recommended to select the value
of seven packets.
"Time To Live" - a parameter used to restrict the stream multicasting range. A
number between 1 and 255 is entered in this box. Each time that an IP
stream passes through a router, the TTL is reduced by one unit. The stream
will be rejected by any router when the TTL value is reduced to zero.
"QoS" - quality of Service. The drop down list offers five differentiated service options or Diffserv. These options relate to the
priority that you wish to assign to the streaming packets on their routes through switches or routers that are QoS management
capable.
QoS values
:
1 -
Top priority
2 -
High priority video
3 -
Low priority video
4 -
Video and voice
5 -
Best effort
(best effort made to correctly deliver the video data and the associated audio data)
"Count of output streams" - count of output streams, displayed in the "Output streams" table bellow. Can be selected
from one to twenty five. After updating ot the FR input parameters this count is automatically set to input stream count value.
"Send IGMP query messages" - enable of the IGMP query messages transmitting. Enable this function when the streaming
output of module is connected to the menageable Ethernet swith with IGMP snooping support. In order for IGMP snooping
to function, a multicast router must exist on the network and generate IGMP queries. The tables created for snooping are
associated with the querier. Without a querier the tables are not created and snooping will not work. When the IGMP query
messages send enabled, the module acts as the multicast router. It is sufficient to enable the IGMP query in one module per
one Ethernet switch.
Once the different data values have been entered, click on "Update" to conclude the streaming settings.
