// Input Parameters:

//
// Return Value:
//  Dcf8710_GetSignalData is always considered valid, whether the demodulator 
//  is locked or not, and irrespective of whether the demodulator is being 
//  used for scanning (through the requests above) or is connected using the 
//  normal demodulator functions. A FAILURE response is expected only if the 
//  demodulator control driver does not provide the capability. A set request 
//  is always invalid and should result in an immediate FAILURE response.
//
// Description: 
//  Gets information on the quality of the signal being received by the 
//  tuner and demodulation hardware.

// Function Name: 
//   Cu1216_ScanRequest

// Input Parameters:
//   pRequest - Pointer to o_demodulator_scan_request defined in OpenTV
//
// Return Value:
//  If the scanning operation is still in progress or an error was encountered, the
//  demodulator control driver should return FAILURE for a get request. Similarly,
//  the demodulator control driver should return FAILURE for a set operation if a
//  scanning operation is in progress or a located signal source has not been
//  unlocked.
//
// Description: 
//  Initiates a scanning operation for the demodulator identified by the 
//  last successful Dcf8710_SetScanMode (per demodulator).
//  When the demodulator locates a signal or encounters an error, a callback 
//  called with NOTIFY_Dcf8710_LOCKED.

// Input Parameters:
//   o_demodulator_type - Define in OpenTV specification includes two fields:
//      index - Specifies a value between zero and (number_of_demodulators-1),
//              where the number_of_demodulators value is obtained from the
//              Dcf8710_Query.
//      demodulator - Is a returned value that identifies the type of demodulator
//                    device using the following OpenTV-defined types:
//                    SATELLITE_DEMOD  0x0100 to 0x01ff
//                    CABLE_DEMOD      0x0200 to 0x02ff
//                    TERESTRIAL_DEMOD 0x0300 to 0x03ff
//
// Return Value:
//  The demodulator control driver should return FAILURE if the provided index is
//  invalid.

// Description: 
//   This function retrieves the type of specific demodulator
