Description:Features: 1) Digital QPSK modulation for system stability, reliability and durability 2) Built in Pay-per-view functionality 3) DVD quality transmissions 4) DVB standard algorithm Conditional Access (CA) software 5) Good for rural or undeveloped areas without cable 6) 3 x 40MHz bandwidth, 36 digital streams are transmitted, with a maximum transmission of 45 streams Specifications and notes: 1) Power: 100W 2) Range: 40km 3) An AV signal is inputted to an MPEG-2 encoder, the encoder outputs the data transmitting stream (TS). The TS is inputted to the multiplexer, and then to the QPSK modulator. An RF signal is produced for transmission by a microwave emitter system. One AV signal needs one encoder 4) All streams are encrypted by the CA system: the end user must be enabled by the system operator to decrypt the stream through a set top box (STB). The STB decrypts the digital video stream 5) Digital TV RF signals are transmitted by fiber cable system to the emitter room, and then the signals are transmitted through the emitter and antenna system 6) The end user receives the digital air radiated signals through a microwave receival antenna and watches video via an STB 7) Transmission towers higher than 100m must be grounded against lightning
