# DVB Data Services

With the
(Pic 1) you can use IP-based DVB data services. Data broadcasts received by the
will be treated in the same manner as if received by a network card. This is why the reception of arbitrary IP-based DVB data is possible, as is integration with the Windows network architecture, and thus, compatibility to other Internet applications. Since the
doesn't receive data from a "normal" network but by means of DVB data broadcasting, some specific additional parameters need to be set. The
allows the setting of any necessary related parameters.

Like our other applications, to make the
easier to understand, most user adjustable settings incorporate tooltips, which appear after the mouse pointer stays over them for approximately one second. For these to work, the application must be the top level window. Clicking on the title bar or control groups will ensure that this is the case. In order to use the
as a network card, the front-end settings and filters must be configured.

## Tabs

The front-end is the input section of the
, consisting of tuner, and demodulator
. All settings that are necessary for reception of a DVB signal will be configured in the Status / Tuner
(Pic 2).
Filters are set to extract the informations from the DVB signal which are relevant for a DVB data service. For that purpose the Filters tab displays the configuration of the filters. The Statistics tab shows the throughput (bit rate) of the filters set. The Setup tab allows the user to enable and disable various features.

## Control

By pressing the Flag button (Pic 4) the
can be displayed in a different language.

Press the Help button (Pic 4) to get additional information about the tab which has the focus.

Changes made in the tabs will become effective and be saved when the Apply button is pressed (Pic 4).

The application window becomes hidden with the Hide button (Pic 4). You can show the window again by double clicking the smiley symbol in the systray. Since this symbol (Pic 3) is synchronized with the state smiley in the application window (Pic 5) it may appear red, dark green, or light green.
If you want the window to be hidden automatically on start up, enable this feature in the Setup tab.

You can close the application with the Exit button (Pic 4). The Setup tab has a setting which allows the user to get a user confirmation request before actually quitting.

## Reception state

Pic 5 shows symbols allowing a permanent observation of the tuner's reception state.
The upper box displays the signal quality, while the lower box indicates the signal level. The current color of these boxes gradually corresponds (colorless, red, orange, yellow, light green) to colored crossbars in the Status / Tuner tab (Pic 1) displaying exact values.
The smiley serves as an additional quick display of the reception state. The three following states are signalled:

red: | No DVB signal, front-end not synchronized, no data reception.
dark green: | DVB signal detected, front-end synchronized, no data reception on the selected filters.
light green: | DVB signal detected, front-end synchronized, data reception on the selected filters in progress.

## Services

In conjunction with the
, a service is a set of all parameters necessary to receive a DVB data service. With the selection of a service, all adjustments are made in such a way that the appropriate DVB data service can be used. Changes of any parameter have no effect until the Apply button is pressed. The parameters needed to use a DVB data service (frequency, symbol rate,
, PID, IP or MAC address) should be provided by the service provider.

### Selecting a service

A service is selected by opening the Service selection list field (Pic 6) and clicking on an entry. The last service selected will be restored when this program is run again. The New, Change and Remove buttons are used for the service management.

### Adding a service

A new data service can be added using the New button (Pic 6) to open the Add data service dialog. In the Name of data service box (Pic 7) you can type in the name for the new service. The parameters of this new data service can be copied from any existing data service to avoid having to enter all parameters again. Once the new data service has been added, the parameters can then be modified and set with the Apply button (Pic 4). Press OK for installation of the service, Cancel will discard the data.

### Changing a service name

Clicking the Change button (Pic 6) opens the Change data service dialog box (Pic 8) you can change the name of an existing service. Clicking OK to set the new name and overwrite the old name. Cancel discards the change.

### Removing a service

Clicking the Remove button (Pic 6) deletes the current service from the Service selection list with all its associated parameters.

### Search for services

Clicking the Scan button (Pic 6) opens the Search for EON services dialog window (Pic 9). Select the scan options channels, modulation, and symbol rate(s) before you start the the search by clicking the Start scan button. Abort scan allows you to stop the search manually. After closing the dialog window (Quit) newly found services will be added to the list box (Pic 6) automatically.

### Service AutoTuning

### Service: AutoTuning

Is an automatic configuration mechanism for accessing the IP/MAC multicast streams with the
. AutoTuning is based on the EN 301 192 DVB specification for data broadcasting and follows the SES Astra "Multi-transponder - Implementation Guideline for IP Multicast Services". It enables a completely self tuning when accessing IP/MAC streams on one or more transport streams, and even on other networks. AutoTuning is possible in networks that make use of the IP/MAC Notification Table (INT) only.
By selection the service AutoTuning a scan will be started. If there are more networks with data services (platforms), a dialogue for selection of the requested platforms is shown. Afterwards the information of IP/MAC Notification Table (INT) are evaluated.
A selection list (picture 9) with which you can also set a certain platform is located in the register card Settings. Because of that the dialogue for platform selection is not shown and the selected platform is used. With selection "automatic" the selection dialogue is shown again.
