Hi folks,I'm using dvbstreamer for DVB-T in the Netherlands where pretty much allchannels are scrambled using Conax encryption (digitenne). I've got atechnotrend T-1500 budget card with optional CI reader with a Conax CAMinstalled and a valid smartcard.Using Kaffeine, everything works properly. Scrambled channels areproperly decrypted and displayed. However, when I use dvbstreamer, onlythe free-to-air channels work correctly. Tuning to a scrambled channel(which kaffeine plays correctly), does start the streaming, only theresulting stream cannot be played by mplayer or xine, so I'm assumingdvbstreamer doesn't use the CAM.Does dvbstreamer support Conditional Access and if so, how can I tell itto decrypt a scrambled channel?regards,Erik van ZijstThread view.
Multichannel Professional DVB-S-S2 satellite receiver IRD with IRDETO BISS CONAX Nagarvision decryption and HDMI and SDI and IP out with TLV400S Virenza with decryption. A satellite TV system must face the following challenge: it is one-way. The receivers cannot do anything but receive; they cannot emit anything.

Hi there.As far as I'm aware DVBStreamer doesn't support any type of CAM.Although I could be wrong. I'm sure the main developer will be able totell you more.Sorry I couldn't be of any more help.Erik van Zijst wrote: Hi folks, I'm using dvbstreamer for DVB-T in the Netherlands where pretty much all channels are scrambled using Conax encryption (digitenne).

Having said all that it may be possible to add support via aplugin, this would be fairly easy using the linuxdvb CAM library, as asfar as I know the only thing that needs to be passed to the CAM is the PMT(stripped of anything by CA descriptors).CheersAdam.
Viaccess is a conditional access system edit by Orange S.A.. There are six versions in use today, Viaccess PC2.3, Viaccess PC2.4, Viaccess PC2.5, Viaccess PC2.6, Viaccess PC3.0, Viaccess PC4.0, Viaccess PC5.0, and Viaccess PC6.0.
Viaccess was developed as the digital version of the EuroCrypt system used with the hybrid MAC system,
The first version is sometimes referred to as Viaccess 1, and the latter three, although different, as Viaccess 2. PC2.3 and PC2.4 are known to be ineffective, and many set-top boxes can be 'patched' to decrypt Viaccess signals without payment, however PC2.5 and PC2.6 are secure, with PC2.5 remaining secure two years after its first commercial deployment. PC2.6 was introduced at the end of 2005. PC3.0 was introduced during mid-2007.
There are two modifications of Viaccess PC2.3 in use. The first, known as TPS Crypt, is used by TPS. Despite being compromised also, the TPS Crypt system has been further modified to use Advanced Encryption System (AES) keys. These AES keys were originally updated once weekly, however after this inconvenienced unauthorised viewers little, a second TPS crypt system was introduced, by which keys are changed every 12 minutes, with keys being sent over TPS's internal Open TV system. This therefore meant that only TPS receivers could receive the new AES key, and not the insecure TPS subscription cards. Monitoring and analysing of the keys by hacking groups, however, has brought about key lists, where the AES keys have been successfully predicted. Implementation of this procedure of automatically updating keys has proved difficult, if not impossible, to implement on many satellite receivers, rendering the TPS Crypt AES system a general success.
The second Viaccess modification, called ThalesCrypt, is used by Canal Satellite France to protect its contents on the transport network to the head-ends of the cable networks; it is an over-encryption mechanism of the original protocol encryption keys.
Viaccess is currently used by a large number of providers. These include:
Team:Media Bosnia Some programs
Viaccess is the 3rd largest conditional access system provider in the world (in 2004).
Viaccess is also a subsidiary of Orange S.A. which offers pay TV and DRM enabled software.
Orca Interactive is a subsidiary of Viaccess which offers IPTV Middleware since 2008.
