IBDA_DiseqCommand::put_DiseqUseToneBurst Method
[This documentation is preliminary and is subject to change.]
Enables or disables Tone-Burst commands.
Syntax
HRESULT put_DiseqUseToneBurst(
[in] BOOLEAN bUseToneBurst
);
Parameters
- bUseToneBurst [in]
If TRUE, Tone-Burst commands are enabled. Otherwise, Tone-Burst commands are disabled.
Return Value
If the method succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code.
Remarks
The Tone-Burst command uses a 22-kHz carrier signal to select either source position A or source position B.
Typically the driver enables or disables Tone-Burst as needed when the application calls IBDA_DiseqCommand::put_DiseqLNBSource. However, you can use the put_DiseqUseToneBurst method to switch this mode on or off, either to improve channel switching or to maintain compatibility with particular equipment. Note that using Tone-Burst can increase the amount of time required for tuning by about 40 milliseconds.
