For sure, this new kind of card add a lot of flexibility as the CI is completely independent. I wondering if a parameter can be added to the driver in order to make the card working like a classic one: - Having the tuner#1 working with the CAM the classic way: * Keep the frontend0 device as it is for controlling the tuning parameters * Create the ca0 and sec0 devices attached to the CI like it is done now * Send the full TS stream from the demodulator unfiltered to the CI interface (CAM usually need full TS stream for working correctly - The Multi Transponder Decrypt advertised has a risky future with all the new protections planed for smartcard and CAM). Is this can be done directly in the APB7202 chip or all data has first to be retrieved by the kernel before being send back to the CI trough sec0? * Create the dvr0 and demux0 devices for the sec0 output - Having the tuner#2 working without the CAM, with its demux1, dvr1, frontend1 devices It may help to keep compatibility with existent DVB applications. What do you think?
