DVB-T Samsung Tuner release note

version 2.0.0.0 
building date:2004.1.30
filename:DVBTDLL.dll

The version 2.0.0.0 functions interface of dvb-t  is the same as the old version.
The only few and useful functions are implement.
Below fuctions are fully implement.
The "pMER" parameter of DVBT_GetSN is not implement.
So it always return the "zero".

DVBTDLL_API BOOL _cdecl DVBT_INIT_IO(void);
DVBTDLL_API void _cdecl DVBT_FREE_IO(void);
DVBTDLL_API BOOL _cdecl DVBT_SetTuningValue(UINT RFfrequency);
DVBTDLL_API BOOL _cdecl DVBT_AcquisitionTask();
DVBTDLL_API long _cdecl DVBT_GetLastLockFrequency(void);
DVBTDLL_API BOOL _cdecl DVBT_GetSN (pu16_t pSN, pu16_t pMER);  // returns Signal/Noise in [dB*10]
DVBTDLL_API BOOL _cdecl DVBT_GetBer(pu32_t pPreViterbi,   // returns error rate in [1e-6]
                    pu32_t pPostViterbi,  // returns error rate in [1e-6]
                    pu32_t pPacketError); // returns raw error count 
DVBTDLL_API BOOL _cdecl DVBT_ResetTuner ();

"DVBT_SetChannelParams" is only the Bandwidth parameter needed to be setup.
You only can get  the valid value of pSigBandwidth's parameter pSigMirror's parameter and  from "DVBT_GetChannelParams"

DVBTDLL_API BOOL _cdecl DVBT_SetChannelParams (s16_t  SysFrequencyOffset, // in [kHz] 
                               s16_t        SigFrequencyOffset, // in [kHz] 
                               Bandwidth_t  SigBandwidth,       // BANDWIDTH_8MHZ, BANDWIDTH_7MHZ, BANDWIDTH_6MHZ 
                               Mirror_t     SigMirror);         // AUTO, NORMAL, MIRROR
DVBTDLL_API BOOL _cdecl DVBT_GetChannelParams (ps16_t  pSysFrequencyOffset,
                               ps16_t       pSigFrequencyOffset,
                               pBandwidth_t pSigBandwidth,
                               pMirror_t    pSigMirror);




Below are the functions  not to be implement.
When you call the function , it always return true.
 

DVBTDLL_API BOOL _cdecl DVBT_SetOfdmParams (Mode_t   Mode,  // AUTO, MODE_2K, MODE_8K 
                            Guard_t  Guard,           // AUTO, GUARD_32, GUARD_16, GUARD_8, GUARD_4 
                            Const_t  Constellation,   // AUTO, CONST_QPSK, CONST_QAM16, CONST_QAM64 
                            Hier_t   Hierarchy,       // AUTO, HIER_NONHIER, HIER_ALPHA_1, HIER_ALPHA_2, HIER_ALPHA_4 
                            Prior_t  Priority,        // PRIOR_HIGH, PRIOR_LOW 
                            Rate_t   CodeRate);       // AUTO, RATE_1_2, RATE_2_3, RATE_3_4, RATE_5_6, RATE_7_8 
DVBTDLL_API BOOL _cdecl DVBT_GetOfdmParams (pMode_t  pMode,
                            pGuard_t pGuard,
                            pConst_t pConstellation,
                            pHier_t  pHierarchy,
                            pPrior_t pPriority,
                            pRate_t  pCodeRate);

DVB-T Samsung eeprom release note

version 2.0.0.0 
building date:2004.1.29
filename:eeprom.dll


DVBTDLL_API BYTE DVB_ReadEEPROM( int address);

DVBTDLL_API BOOL DVB_GetDeviceName(char * ch);
