Camera Control and Tally between SDI and HDMI
Using Blackmagic Pocket Cinema Camera with ATEM Constellation 8K
In this scenario, the micro converter is used to connect the camera’s HDMI output to the
ATEM’s SDI input. The bidirectional converter allows the camera control and tally data to be fed
back through the converter and into the camera via the Consumer Electronics Control CEC data
in the HDMI signal.
The Micro Converter’s HDMI output can be used for remote monitoring.

Blackmagic URSA with ATEM Mini
Here the converter is used to connect the camera’s SDI output to an ATEM Mini’s HDMI input.
The SDI signal from the camera is converted to HDMI and sent to the ATEM Mini. CEC data is
returned to the Micro Converter and converted to CCU and tally data, then sent back to the
camera over SDI.

Using 2 Micro Converters as an SDI Extender
As SDI allows connections over longer distances than HDMI you can connect 2 BiDirectional
Micro Converters together using an SDI cable and extend the range of HDMI equipment while
maintaining camera control and tally data.
For example, an ATEM Mini can be connected to a Blackmagic Pocket Cinema Camera 6K. As
shown in the example below, CEC data from the ATEM Mini is sent to the first Micro Converter
over HDMI and then sent between the converters as CCU and tally data over SDI. The second
converter then sends CEC data back to the camera over HDMI.
