We can configure a device which is not listed (the application couldn’t detect it), if we know that it is available (check by a
ping to the IP address using a command console) and we know its IP address. We have to click in the menu option
“Manager/Manual connection”. If the application achieves to connect the device, this will be added to the list with an
unknown state (?).
Whatever operation that implies a deletion of the configured services in the device, as is a change in the operation mode
or in the tuning/demodulating parameters, the application warns and invites us to save the previous configuration in a file
for its subsequent recovery.
Before analyzing the search and configuration of services, we are going to see a summary of the different options in the
streaming mode. We analyze further the cautions to follow in order to configure DVB-S / DVB-S2 devices in case they
are sharing LNB. Finally, we will see the features in the configuration of devices that include the hardware option
"Common Interface".
2.4.1. Streaming Mode
The streaming mode of a service refers to the content and encapsulation protocol over what is sent via ethernet related to
the service, and it is depending on the device operation mode:
In SPTS mode, there are two possibilities:
- Transport Stream: The transport stream related to the configured PIDs for the service is encapsulated in IP
using UDP or RTP protocols and unicast or multicast addressing. In this case, the device generates and
sends the service information tables (PAT, PMT y SDT).
- MultiProtocol IP (MPE): The device sends via ethernet the IP packets included in special sections MPEG
(encapsulated in TS) that are transmitted in DVB. Using this streaming mode, the device can filter the IP
packets corresponding to the configured multicast IP address, inside the MPEG section related to the
configured PID (only a PID per service). If “Uses IP to MAC mapping” tick is marked, the device will filter all IP
packets corresponding to the first ‘x’ bytes (less meaning) of the MAC address (using multicast to MAC
mapping), associated to the configured PID. If this tick is not marked, the device will extract all IP packets
corresponding to the configured PID.
In MPTS mode, the filtered information can be encapsulated in IP using UDP or RTP protocols and unicast or multicast
addressing. In this case, the device doesn’t generate any service information table.
2.4.2. Search for the available services/frequencies
This step is not necessary if the services or transponders to configure are already in the “Database” in the SPTS or MPTS
mode respectively, or they are previously saved into a configuration file. If they are not, we have to make a previous search.
Independently the operation mode, we always refer to a services search, although depending on the operation mode, the
“Database" tab will show the list of available services (SPTS mode), or a list of available transponders (MPTS mode).
