The FLOW 4K from Science Image is a highly versatile signal converter and optical video receiver and transmitter, all in one compact device.
The FLOW 4K converts 1 channel of 12G-SDI or HDMI 2.0 4K60 and below video sources into any format specified by the user in the range of HD to 4K60, and output through the 12G-SDI or HDMI 2.0 ports.
The Up/Down/Cross conversion function currently supports at least 35 types SMPTE and PAL/NTSC standard formats, with more formats available in the future by way of firmware updates.
To quickly view the device’s settings, a convenient 1.3-inch OLED screen displays the unit’s working status and parameters, input/output format and other content in real time.
The FLOW 4K has built-in HDMI 2.0 and 12G-SDI optical transceivers for sending and receiving video signals over long distances. Users can choose different optical modules to transmit different distances, with the maximum support of 20 kilometers.
