[dvblast-devel] dvblast & remote CAM decoding

Wed May 30 08:54:05 CEST 2018

Hello Daniel,

You are on the right track.
Like you said, the cam shouldn't care if the TS comes from network, tuner,
asi etc.

I envision a patch for tsdecrypt to be able to write and read to a stand
alone CAM/CI such as the Digital Devices Single CI Slot.

If anyone knows who might be able to write such a patch, please let me know.

Thanks
