NDS3542U is a high performance 4K Encoder modulator designed by Dexin. It integrates encoding (H.265/HEVC and H.264/AVC), multiplexing and modulating functions in one standard 1U case.

It support two HDMI (2.0) channel UHD signal input (hot redundancy) for encoding, and also 2 ASI & 32 IP input for remux. To enhance the transport capacity, it combines 1 DVB-C/T carriers output with one RF port. It is also equipped with 4 ASI ports to mirror out RF carrier and IP port to output TS in 1* MPTS.

FEATURES

  • Support 2 HDMI 2.0 (Mux) input and 1 HDMI 2.0 (Loop out) output

  • Support HDCP 2.2 and HDCP 1.4

  • Support 2 ASI & 32 IP input (MPTS/SPTS) over UDP and RTP protocol

  • Support up to 2160P 60Hz RGB/YCbCr 4:4:4 input
