BDA Implementation Options

[Ravichandran k]

Hi all,

I am new to BDA. I am now in porgress of developing the BDA driver for DVB-S application.

I own a USB device ( Newmi DVB-S USB TV BOX ).

They have provided ProgDVB exe for testing this driver, its working fine able to watch video.

I need help to implement the BDA driver?

I have the ScanChannelsBDA sample code with me and it is for DVB-T, what are the chages need to be done for DVB-S?

Also I have attached the ScanChannelsBDA sample code.

Attached File(s)

 ScanChannelsBDA_2.0.0.7_src.zip ( 71.83K ) Number of downloads: 87

This is a lot of effort unless you had access to the CAM interfaces for each card manufacturer. You may wish to rethink if your after implementing CA transponders.

Thanks bear

Is there any possibilty to get the transport stream directly from the BDA tuner card. If yes, what are the interfaces to be used?

IDVBSLocator
IDVBTuneRequest
IDVBTuningSpace2
ITuneRequest
ITuner

Thanks bear

I need to recieve the entire tranport stream from Ituner to a buffer. Is it possible?

IID_ITuner is an interface derived from the Network provider to setup the Tuner filter's tuningspace, if you need to sample the transport stream then you could to insert a sample grabber filter on the output of the tuner/capture or capture filters. You can always use the BDA graph interfaces and enumerate the service info from the TIF interfaces or use your own sections parser code to get the info you need similar to scanchannels or epgscan.
