Product Description

Product Outline

STHM-3400 is a high-performance HDMI 4K modulator with advanced encoding technology. It is processing uncompressed 4K video signals at eight times the bit rate of current HD sources, and it offers incredible compression efficiency.

The HDMI modulators not only integrate encoding (H.265/HEVC and H.264/AVC) but also has multiplexing and modulating functions in one standard 1U rackmount chassis with better heat dissipation. It supports two HDMI (2.0) channel UHD signal inputs (hot redundancy) for encoding, and 2 ASI & 32 IP inputs for remux. 

To enhance the transport capacity, the encoder modulator combines 1 QAM DVB-C or 1 DVB-T RF carrier output with one RF output port. It is also equipped with 4 ASI ports to mirror our RF carrier and an IP port to output TS in 1* MPTS. The HDMI to RF modulator is making live UHD delivery available for satellite, cable, terrestrial, and fiber networks.
