HP8653U 4K Encoder Modulator

Input:1×HDMI,2 ASI,128 IP Output:1*ASI,4 MPTS over UDP Video Encoding:H.265/HEVC, H.264/AVC Audio Encoding:MPEG-1 Layer 2, LC-AAC; DD AC3 passthrough Min Order:1pcs Size:482mm×455mm×44.5mm (W × D × H)

HP8653U 4K Encoder Modulator

Product Overview

HP8653U is a high performance 4K Encoder modulator designed by Catcast. It integrates encoding (H.265/HEVC and H.264/AVC), multiplexing and modulating functions in one standard 1U case. It support one HDMI (2.0) channel UHD signal input for encoding, and also 2 ASI & 128 IP input for remux. To enhance the transport capacity, it combines 4 DVB-C/T carriers output with one RF port. It is also equipped with 4 ASI ports to mirror out one carrier and IP port to output TS in 4* MPTS.
