/**
|
|
* dvbapi-support for Matrix Cam Air
|
|
*
|
|
* The code is based partially on module-dvbapi-azbox.
|
|
* the (closed source) oscam that comes with the MCA is
|
|
* apparently based on svn-revision 5124-5242.
|
|
* DEMUXMATRIX is essentially the old DEMUXTYPE which
|
|
* has changed since then.
|
|
*
|
|
* We may be able to implement add/remove-filter
|
|
* by adding/removing them from DEMUXMATRIX
|
|
* and reexecute mca_write_flt
|
|
* In some cases the MCA will send ECMs for multiple PIDS
|
|
* So it is apparently able to handle multiple filters
|
|
