Описание:

     MPEG-2 кодер Crypton ENC810ASI представляет собой функционально законченное устройство преобразования аналоговых сигналов в цифровой поток DVB. Имеет ASI выход, предназначенный для работы совместно с DVB модулятором. Основное применение ENC810ASI находит в головных станциях кабельного телевидения, сетях МИТРИС, MMDS и LMDS, в системах видеонаблюдения.

Возможности:

• Один аналоговый вход. Видео и стерео звук преобразуются в DVB совместимый поток (MPEG2 видео, MPEG1 Layer 2 звук).
• ТВ канал. Канал может быть настроен как ТВ канал (видео и стерео звук).
• Цифровой ASI выход. С выхода устройства сигнал может быть подан на канальный модулятор, поддерживающий интерфейс ASI, на мультиплексор или другое устройство для дальнейшей цифровой обработки.

Description:     Crypton DTV server COD881 ASI – is a multifunctional server for pay-TV services. COD881 ASI is a perfect solution for converting analog signals into DVB digital stream. ASI output is designed for joint operation together with DVB modulator.     In arbitrary order COD881ASI can scramble 8 digital TV-programs by aid of dynamic keys, which are unique for every program. Subscribers message system (SMS) allows having up to 16 million subscribers in aggregate for all of the eight channels. According to ETS-300468 specification COD881ASI inserts PSI and SI information into the stream.     Control and status monitoring of COD881ASI are performed by the operator's personal computer running “Crypton DTV Master” software. Communication media between server and computer is a regular TCP/IP network (100 BaseTX, UTP5 cable, RJ45 plug, can run directly and via active network equipment). There is no restriction in the quantity of network equipment.     Typical applications of COD881ASI are head-end stations of digital cable, MITRIS, MMDS- and LMDS networks.

Description:

    DTV server Crypton COD881MS – is a multifunctional server for pay-TV services. COD881MS is a perfect solution for converting analog signals into DVB digital stream. L-band (950-1750 MHz) signal at the output of built-in QPSK modulator by aid of frequency converter can be carried to a desired SHF frequency (for instance, into Ku-band for satellite broadcast systems or MITRIS).
    In arbitrary order COD881MS can scramble 8 digital TV-programs by aid of dynamic keys, which are unique for every program. Subscribers message system (SMS) allows having up to 16 million subscribers in aggregate for all of the eight channels. According to ETS-300468 specification COD881MS inserts PSI and SI information into the stream.
    Control and status monitoring of COD881MS are performed by the operator's personal computer running "Crypton DTV Master" software. Communication media between server and computer is a regular TCP/IP network (100 BaseTX, UTP5 cable, RJ45 plug, can run directly and via active network equipment). There is no restriction in the quantity of network equipment.
    Typical applications of COD881MS are head-end stations of digital cable, MITRIS, MMDS- and LMDS networks.

Description:

    RMD 940 is a high performance remodulator, designed to recover the key features of digital QPSK-modulated radio signal, distributed for long distances by aid of multiple retransmissions.     There are 4 independent remodulator-channels composed of L-band (950-2150 MHz) module tuner at the input and L-band QPSK modulator module at the output.

Crypton DTV Server Remultiplexer COD980RMS with QPSK modulator

Description:

    DTV Server Remultiplexer COD980RMS is a remultiplexer equipped with the functions of DVB scrambler and subscriber service server of conditional access system "Crypton". Input transport stream ASI interface and built-in L-band QPSK modulator, which is by aid of frequency converter could be transferred to a desired UHF-band (for instance to Ku-band for satellite broadcasting systems and MITRIS) or by aid of QPSK/QAM transmodulator to RF-band for MMDS networks and head-ends, enable to arrange broadcasting of digital TV-programs with maximum quality and minimum capital investment.
    8 ASI inputs are available in COD980RMS. Transport streams of digital TV-programs selected for being multiplexed are fed on each of 8 ASI inputs. Transport streams can be scrambled in arbitrary order by the dynamically changing keys, which are unique for each program. Subscribers Message System allows having up to 16 million subscribers.
    The control computer performs all the tasks of device management and its condition monitoring by aid of "Crypton DTV Master" software through TCP/IP communication.
    COD980RMS is mainly applied in head-end stations of digital cable, MITRIS, MMDS- and LMDS-networks.
