    QAM Modulator QTX-2X

    Categories: Digital broadcasting, QAM modulators QTX-2* series Tags: CTV, DVB-C, QAM modulator, QTX-2
    • Description

    Development is in progress.

    The QTX-2X device is designed to form 16 transport streams in DVB-C format, transmit selected channels to the frequencies and transmit them to the cable television network. Up to 16 STV-Crypt conditional access system scramblers can be included in the device, which allows organizing a paid access system for watching television programs in cable television networks with the SCR-1 (Scrambler Controller) device. The presence of the built-in multiplexer allows you to transfer programs from any of the inputs of the transport stream (4xASI, 2xGbE) to any output (16xQAM (16-256), 2xGbE). Control and configuration via 100 Mbps Ethernet (web browser). Support for Simple Network Management Protocol (SNMP) allows you to monitor the current state of the device.
