DVBlast is a simple and powerful MPEG-2 transport stream demux and streaming application with several input methods, such as Linux DVB supported cards (DVB-S, DVB-S2, DVB-C, DVB-T, etc.), ASI cards, and UDP/RTP streams carrying a transport stream. It outputs one or several UDP/RTP streams carrying transport streams with hardware or software PID filtering, PID-based or service-based demultiplexing, and optional descrambling via a CAM device.
tsdecrypt reads an incoming MPEG transport stream over UDP/RTP and then decrypts it using keys obtained from OSCAM or a similar CAM server. Currently supported crypto systems are Conax, Cryptoworks, Irdeto, Viaccess, Mediaguard (Seca), Videoguard (NDS), Nagra, DRE-Crypt, and Bulcrypt. BISS and constant code words are also supported. tsdecrypt communicates with a CAM server using the cs378x (camd35 over TCP) protocol or the newcamd protocol.
