More about this category
The complete BLANKOM range: everything needed to acquire, encode, process and distribute professional video over IP and DVB networks.
The catalogue is organised the way a headend is built. Signal acquisition starts with the DVB and IPTV receivers and the DVB-to-IP gateways; encoding covers HDMI, SDI, DisplayPort, VGA and analogue sources up to 4Kp60; processing includes transcoders, multiplexers and protocol converters; and distribution covers QAM, COFDM and DVB-S2 modulators, IP decoders and set-top boxes. Satellite infrastructure — multiswitches, L-band matrices, redundancy switches and RF over fibre — sits alongside, together with the installation cable used to wire it all.
Every unit is managed over a web interface, designed for continuous operation in a 19″ rack, and supported by engineers in Germany. If you are not sure which unit fits your signal chain, describe the sources and the destination and we will propose a configuration.
