S3536S (V2) Encoder Modulator – ISDB-T (8/16/20/24-Channel) is a high-performance, fully integrated head-end solution that consolidates encoding (with demodulation), multiplexing, and modulation functions into a single compact 1RU chassis. It offers versatile input configurations, supporting 8, 16, 20, or 24 HDMI channels (or a hybrid combination of HDMI and tuner inputs), alongside 1 ASI input, 1 USB media player input, and up to 128 IP inputs via the Gigabit Ethernet port. On the output side, the unit delivers multiple DVB-C carrier channels (with DVB-T, ATSC, or ISDB-T options available), and provides MPTS output as a carrier mirror through the GE port, plus 1 ASI output mirroring a selected carrier channel. With its all-in-one architecture, the S3536S (V2) is an ideal solution for small-to-medium CATV head-end systems, offering a cost-effective and space-efficient choice for hotel television distribution, sports bar entertainment setups, hospital patient TV networks, apartment complexes, and other multi-dwelling or commercial video distribution environments.
