I have LE40B679 which is CI+ with additional satellite tuner, but i guess it does not make any difference.
My CAM is Neotion Conax CAS-7 for N-tv - polish provider.
Try to play with writing values to mentioned above mem area. As sbav1 wrote, we have actual video pid @ 0x30110100 byte (or byte+half-byte?), so it will vary with every channel. Try to figure out what exactly kills the signal. You cannot change last three characters, becouse they store PID. Try to:
-Set TV to some FTA channel with CAM inserted
-Read @ 0x30110100 value
-try to modify value by eating it's left part, but do not change last four characters
For example, if you get 0x141A0A1, try 0x41A0A1.
If signal die, try reboot, then set to same channel and try 0x1A0A1.
If still no success, then probably we have totally diferent CAM's and i have luck that mine works :(

TSD/PVR PID filter register bits (a missing explanation[s]):

Code: Select all

## PID filter registers for bank 0|1 (0x30110100|0x30110180); rv=[31..0]

   1) PID: // lldTsDmxSetPidFilter, ...

Also, check out: TDM -> 11 : TD Debug -> 0x04 : spI Debug -> 50 : TSD kernel level debug -> 0 : Tsd monitor
Yields an useful (?) info; may be helpful while trying to clarify some things:

Overall, this CI/CI+ CAM business seems to be awfully complicated :). I can't help very much with that topic, my setup is very simple (non-CI+ B650, no CI/CI+ CAM, just one DVB-T mux with FTA programs only).

But could the only reason why it aint working for me be my CAM module .. or could it also be that my TV provider has some kind of different protection ??
If it is just the CAM ..then I am willing to buy a new one I guess.
Chance that it will work better with different CAM is not a big one, IMO. It may be worth a try, I guess. Perhaps you could just borrow another CAM to perform a test?
BTW, what model / firmware version do you have, exactly?

I'll try to check this firmware version for a possible glitches in PVR code, but [overall] it's not looking very optimistic :(.

- PIP window can be hidden, by turning Chelsea scaler #1 off. It's possible from TDM. Probably doable from Content Library application level with simple SdVideo_Get()/SdVideo_Set() calls (not tested yet).
I would like to implement PIP hide/unhide function in PVR+ but I have no idea how to call the functions you mentioned. I was trying to get PIP window size using function SdVideo_GetPCPosition (correct one?):

Code: Select all

// WARNING! This is probably wrong method! Do not use.
typedef struct
{
  int x, y, w, h;  // I'm not sure!
} SdPoint_t;
extern int _Z21SdVideo_GetPCPosition11SdVideoID_kP9SdPoint_t(int, SdPoint_t *);
//extern int _Z21SdVideo_SetPCPosition11SdVideoID_kP9SdPoint_t(int, SdPoint_t *);
SdPoint_t pip_pos;
// call exeDSP function:
_Z21SdVideo_GetPCPosition11SdVideoID_kP9SdPoint_t(0, &pip_pos);
but it returned zeros only. I am not sure about first parameter (tried 0 and 1) and if the second parameter is such struct as defined above. Can you provide a function to hide/unhide PIP window? Then I could make some tests.

I need PIP hide function for watching external (HDMI) video source with audio coming from internal DVB-C tuner.

I am also thinking about multi-channel (single mux) recording but I need more information. I need to know what mux (MUX ID or TSid, Network ID) we have now or know current channel number and DVB-type (-C, -S or -T). Then we could read channel table from mtd_rwarea files and select PIDs for current mux only (to fill filter table with allowed PIDs only).
