TBS: CI/CAM support and other improvements (6 Viewers)

That is a bit crap. Shouldn't the driver "know" based on what we're asking it to tune to? Or am I missing something?

 

[onelegend]

Indeed, I did ask the question originally but had no mention of it in reply

We know the card can tune both dvbs and dvbs2 fast atleast - need tbs to sort their code out so both can tune fast at same time

 

[DJBlu]

typedef struct _BDA_NBC_PARAMS
{
int rolloff;
int pilot;
int dvbtype;// 1 for dvbs 2 for dvbs2 0 for auto
int fecrate;
int modtype;
} BDA_NBC_PARAMS, *PBDA_NBC_PARAMS;
dvbtype default value is 0 ,if you lock DVBS2 TP,driver will lock DVBS first then lock DVBS2 ,so it will longer
const GUID KSPROPSETID_BdaTunerExtensionProperties =
{0xfaa8f3e5, 0x31d4, 0x4e41, {0x88, 0xef, 0xd9, 0xeb, 0x71, 0x6f, 0x6e, 0xc9}};
typedef enum {
KSPROPERTY_BDA_RESERVED = 0,
KSPROPERTY_BDA_NBC_PARAMS = 10,
KSPROPERTY_BDA_BLIND_SCAN = 11,
KSPROPERTY_BDA_TBSACCESS = 21
} KSPROPERTY_BDA_TUNER_EXTENSION;
BDA_NBC_PARAMS DVBType;
DVBType.dvbtype = type; 1 for dvbs 2 for dvbs2 0 for auto
//Only need to set dvbtype other parameter do not need to set.
if (m_pKsCtrl->Set(KSPROPSETID_BdaTunerExtensionProperties,
KSPROPERTY_BDA_NBC_PARAMS,
&DVBType,sizeof(DVBType),
&DVBType, sizeof(DVBType)) == S_OK)
{
bRet = TRUE;
}
else
{
OutputDebugString("SetDVBType setInterface Failed");
}

Good News.

We can set the DVB-S/S2 setting.

I'll add it later and give it a whirl.

look forward to testing.

I have only tested this out on a 6984 and 6981 card.

Works with 6981 not with 6984

View attachment TVLibrary_fasterDVB-S2.zip

You need the following driver too.

6981 Drivers

It gets the tune time to around 1 second from 3-3.5 seconds

not lightning quick but faster than before.

Just emailed to ask if they are updating their drivers to allow the rest of the TBS cards to have this feature. Will keep you posted.

The following goes in Turbosight.cs

/// Turbosight.cs

    private enum BdaExtensionProperty
    {
      Reserved = 0,
      NBC_PARAMS = 10,     // Property for setting the DVB-S2 parameter
      BlindScan = 11,     // Property for accessing and controlling the hardware blind scan capabilities.
      TbsAccess = 21      // TBS property for enabling control of the common properties in the BdaExtensionCommand enum.
    }

    private struct BDA_NBC_PARAMS
    {
        public int rolloff;
        public int pilot;
        public int dvbtype;// 1 for dvbs 2 for dvbs2 0 for auto
        public int fecrate;
        public int modtype;
    }

    private const int TbsNBCParamsSize = 20;

        if(channel.ModulationType != ModulationType.ModNbc8Psk && channel.ModulationType != ModulationType.ModNbcQpsk)
            return;
        int hr;
        KSPropertySupport supported;
        _propertySet.QuerySupported(BdaExtensionPropertySet, (int)BdaExtensionProperty.NBC_PARAMS,
                                    out supported);
        if ((supported & KSPropertySupport.Set) == KSPropertySupport.Set)
        {
            BDA_NBC_PARAMS DVBNBCParams = new BDA_NBC_PARAMS();
            DVBNBCParams.fecrate = (int)channel.InnerFecRate;
            DVBNBCParams.modtype = (int)channel.ModulationType;
            DVBNBCParams.pilot = (int)channel.Pilot;
            DVBNBCParams.rolloff = (int)channel.Rolloff;
            DVBNBCParams.dvbtype = 2; //DVB-S2
            Log.Log.Info("Turbosight: Set DVB-S2: {0}", DVBNBCParams.dvbtype);
            Marshal.StructureToPtr(DVBNBCParams, _generalBuffer, true);
            DVB_MMI.DumpBinary(_generalBuffer, 0, TbsNBCParamsSize);

            hr = _propertySet.Set(_propertySetGuid,(int)BdaExtensionProperty.NBC_PARAMS,
              _generalBuffer, TbsNBCParamsSize,
              _generalBuffer, TbsNBCParamsSize
            );

            if (hr != 0)
            {
                Log.Log.Info("Turbosight: Set DVB-S2 returned {0}", hr, DsError.GetErrorText(hr));
            }
        }
       else
       {
            Log.Log.Info("Turbosight: Set DVB-S2 not supported");
       }
    }

And call it in SendDiseqcCommand

      SetDVBS2(channel); // Don't need to know the result of this.
      
      return (successDiseqc && successTone);
    }

Thanks DjBlu!

Will I get away with just running these files in your custom data grabber install or does it need the TBSV2 svn?

Thanks again, been trying to get to bottom of the slow changes for ages!

You'll have to modify it yourself.

The patch file is in the Custom Data Grabber thread.

Then you will just have to add this code in the Turbosight.cs

No prob DJBlu

Thanks for the code - I attempted last night but to compile I need the Win SDK installed, I downloaded over night and in typical MS style - failed to install

I only have 3g web access atm (yes it's painful) and it used up most of my months download allowance

I'll download the full sdk iso when I'm next at my parents house.

Thanks for your help

Talk about laying it on thick! lol

I'll have a look into it in the week if you can wait.

Thanks - Yeh np waiting, Just sticking with your build for time being and put up with the slow changes .

Moved house and broadband supplier can only provide a 1mb connection (2 doors down gets 50! - Currently getting 3 mb on my 3g dongle), if I wait a couple of months I'll be connected on a nice 1gb fibre line though
