2. DVB-IP
IP LAN TV Manager is an application that allows the search, monitoring and configuration of the IP LAN TV devices
grouped under the category of DVB-IP. Inside this category the following types of devices are found:
- IPS 310 (DVB-S / DVB-S2)
- IPT 310 (DVB-T)
- IPQ 310 (DVB-C)
The only difference among these types is the input stage of the device: for the three first types, satellite, terrestrial and
cable, there is a module tuning/demodulator, different for each type, that treats the input RF signal coming from an
antenna or modulator.
There is an additional hardware version for each of these devices, named “Common Interface” (CI) that allows to
descramble encrypted services using up to two conditional access modules (CAM) via PCMCIA interface.
Using IP LAN TV Manager on these devices, we will be able to carry out some management tasks, as well as the
configuration of the streaming services.
The management tasks are:
- Device settings configuration. These settings are the name, network settings, querying status and TTL.
- LNB settings configuration (only in case of DVB-S).
- Update of the firmware embedded on the device.
- Reset of the device, keeping its previous configuration.
- Suspend and resume the streaming coming out from the device.
The configuration of a device will consist basically in the election of the operation mode as well as of the services or
programs that the device will serve to the network in format of "transport stream" encapsulated in IP, utilizing addressing
multicast or unicast. These services must be in the same transponder or channel, because a device, in a given moment,
only can tune in a single transponder.
On SPTS mode (see following paragraph), using this tool, we will be able to modify the services configured, changing the
direction/port of streaming or adding or removing PIDs. Normally a service will consist of an set of PIDs: a video PID, one
or various audio PIDs and perhaps some data PIDs..
2.1. Operation Modes
The device operation mode refers to the filter type that device applies on the input transport stream, and therefore to the
content sent via Ethernet. The device can operate basically in two operation modes, SPTS mode (Single Program
Transport Stream) and MPTS mode (Multiple Program Transport Stream). By default, the device will work on SPTS mode,
and the change of mode is carried out by means of the menu options "Configuration/Set MPTS Mode" and
"Configuration/Set SPTS Mode".
2.1.1. SPTS Mode
In the SPTS mode (Single Program Transport Stream), the device filters part of the information of the input transport
stream. The filtered information is configured in SPTS services (up to eight as maximum) and encapsulated in IP
according to each service streaming configuration. Normally, the SPTS services present a variable bitrate, and in order to
create them, we will start from a list of available services .
2.1.2. MPTS Mode
In the MPTS mode (Multiple Program Transport Stream), the device filters all the information of the input transport stream.
All this information is configured in a single service MPTS and encapsulated in IP according to its streaming configuration.
Normally, the MPTS service present a constant bitrate, the same as the input transport stream. In this mode the device
acts in a transparent way.
In this case, in order to configure the unique service, we will start from a list of available transponders.
