There are several drawbacks using PCMCIA conditional access modules (CAMs) with the Siemens DVB card : - you have to buy one PCMCIA for each conditional access system (Viaccess, MediaGuard, Irdeto, Alphacrypt, Conax, ...) - CAMs are not available for all systems (VideoGuard) you have to buy a CAM interface - if you have several DVB cards, you must buy several CAM interfaces and CAMs and subscriptions - the current DVB driver doesn't support the CAMs very well But there is another solution. The AV7110/7110 contain a DVB hardware descrambler. There would be several advantages to develop CAM software : - Much less expensive - You can share a smartcard between several DVB cards, so record several programs with only one subscription - The CAM software can be changed each time you switch to another channel using a different CA system. You no longer need to dedicate a DVB card for each CA system. - you need only a smart card reader (for example a Phoenix interface) thats costs only from 10 to 20 euros. So I have decided to write a quick and dirty CAM software to validate the idea. I have choosen the SECA/Mediaguard system, because there are problems with Aston CAMs (even with commercial receivers). In the first version, only ECMs (Entitlement Control Messages) are processed, but I plan to add support for EMMs (Entitlement Management Messages) as soon as the first version is functional. I have tested it, but at this time, it only displays the OCW and ECW (Odd Control Word and Even Control Word), since the DVB driver lacks the functions to send the control words to the AV7110. I hope that the driver developers will quickly add these functions, since the AV7110 software is not open-sourced.
