Universal digital station Appear TV SC2000/2100

3

Appear TV StreamCore SC2000 (4RU, 16 sockets) and SC2100 (1RU, 9 sockets) stations are built on the basis of flexible modular platform, which offers the ample opportunities of adapting the station to specific customer’s requirements. The platform enables reception, descrambling, and scrambling of signal, as well as reception and transmission of streams via TCP/IP protocol. SC2000/2100 can be equipped with various input interfaces, such as ASI, QPSK, DVB-S2, and IP. Incoming streams can be descrambled with use of DVB CAM modules or virtual smart cards AES. Also, the station enables analysis and change of content in PSI/SI tables – according to operator’s requirements. Scrambling of streams under AES standard and with use of coding systems (for DVB, prior to issue on ASI or IP output interfaces) is supported.
