Re: Can I do sharing on my LED TV

Hi,
technically it would be possible.
The Common Scrambling Algorithm (CSA) is known
and all a CI Cam does is execute the CSA on the encrypted
transport stream. Software only implementations of the CSA
are available and the TV does have a 600Mhz CPU which
should suffice.
The problem is that everything (including CI stuff) is in
exeDSP which is closed source (with debug symbols).
Hooking the required functions should be no problem,
but you need to identify which functions to hook,
and need a good understanding of how a CI Cam gets
the stream and sends the decrypted result back (I think
it's a callback mechanism of some sort).
