IDVBSLocator2 Interface
[This documentation is preliminary and is subject to change.]
Provides information to enable a tuner to acquire a Digital Video Broadcasting-Satellite (DVB-S) transmission. This interface extends the capabilities in the IDVBSLocator interface to support the DVB-S, Second Generation (DVB-S2) specification, the Digital Satellite Equipment Control (DiSEqC) protocol, and low-noise block converters (LNBs).
Methods
The IDVBSLocator2 interface inherits from IDVBSLocator.
In addition, IDVBSLocator2 defines the following methods.
| Method | Description |
|---|---|
Gets the selected DiSEqC LNB source. |
|
Sets the selected DiSEqC LNB source. |
|
Gets the low oscillator frequency of the DVB system. |
|
Sets the low oscillator frequency of the DVB System. |
|
Gets the high oscillator frequency of the DVB system. |
|
Sets the high oscillator frequency of the DVB System. |
|
Gets the LNB switch frequency of the DVB system. |
|
Sets the LNB switch frequency of the DVB system. |
|
Gets the state of spectral inversion on the DVB-S2 signal. |
|
Gets the state of spectral inversion on the DVB-S2 signal. |
|
Gets the roll-off factor for the DVB-S2 signal. |
|
Sets the roll-off property for the DVB-S2 signal. |
|
Gets the pilot mode of the DVB-S2 signal. |
|
Sets the pilot mode of the DVB-S2 signal. |
Properties
The IDVBSLocator2 interface defines the following properties. The preceding table includes access methods for these properties.
