H.264 AVC/H.265 HEVC HD ASI IP To RF DVB-C/DVB-T 4K Encoder Modulator COL5011U-K1

COL5011U-K1 is a high performance 4K Encoder modulator integrating 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.
