Merge Multiple RCP IP Control Signals Onto a Single SDI Wire

Receives “UDP Camera Control” information over Ethernet and forwards it on the SDI out connector. Used to merge network data from multiple RCPs onto a single SDI wire.

Multiple Controllers, Single Return, Any Switcher. Firmware: ETH2SDI

In this setup multiple SKAARHOJ panels connect with a SKAARHOJ ETH-SDI Link over ethernet which in turn multiplexes this into the 3G-SDI output. If you have the ATEM Talkback Converter 4K or the ATEM Studio Converter this is a great add-on for your RCP/RCP Mini setup.

On the 3G-SDI input of the ETH-SDI Link any 3G-SDI input can be supplied and may even contain ancillary data for color and tally on its own which will be passed through unless incoming ethernet data takes momentary priority. For example, if a Newtek Tricaster supplies a PGM out with tally data to the 3G SDI-in, the tally data will be passed through, but may be overridden if tally data is passed to the ETH-GPI Link over Ethernet from an RCP


Camera Support

The Blackmagic 3G-SDI Arduino Shield supports the following formats: 720p50, 720p59.94, 720p60, 1080i50, 1080i59.94, 1080i60, 1080p23.98, 1080p24, 1080p25, 1080p29.97, 1080p30, 1080p50, 1080p59.94 and 1080p60, but the camera doesn´t have to be running the same video format as the program input, so you can use cameras in Ultra HD while the camera protocol is sent over HD signal to the camera

Single Controller, Multiple Returns, Any Switcher. Firmware: ETH2SDI

In this setup a single SKAARHOJ panel connects with multiple SKAARHOJ ETH-SDI Links over ethernet which in turn multiplexes this into the individual 3G-SDI outputs on each ETH-SDI Link unit. Tally needs to originate from the single SKAARHOJ panel. Either by having a SKAARHOJ panel with GPI input, by using our Device Cores if the video switcher is supported or by having a ETH-GPI Link to interface with GPI and relay information to the shading panel.

The SKAARHOJ ETH-SDI Link mainly functions as a device that receives Blackmagic Camera Control data over UDP and embeds it on SDI (“ETH2SDI” Firmware). However, a number of other firmwares are possible.

  • “ATEM2SDI” firmware: Embeds color data on SDI in a situation where a network connection to an ATEM switcher is feasible while an SDI connection is not, for instance if there are thousands of kilometers between the ATEM and the camera and a VPN can be used to channel the network through. In such a scenario, the ETH-SDI Link would establish a network connection to the ATEM and use it to extract the data otherwise embedded on SDI out of the switcher and embed it “locally”. Requires low latency network.

Note for SKAARHOJ controllers with Blackmagic 3G-SDI Arduino Shields and Studio Fiber Converter/Camera Fiber Converter:

We have tested Blackmagics fiber converter products in general to work with SDI output. This includes the Mini Converter, ATEM Camera Converter, ATEM Studio Converter and ATEM Talkback Converter 4K. The only product we know does not work is the Studio Fiber Converter/Camera Fiber Converter. This product is not compatible with their own 3G-SDI shield which is the component we use inside the RCPs and other products. While the Studio Fiber Converter/Camera Fiber Converter will forward shading data from an ATEM switcher it will not do so for the 3G-SDI shield.

Bottom line is this: We cannot change this situation, only Blackmagic Design can decide to upgrade either the Studio Fiber Converter/Camera Fiber Converter or the 3G-SDI Arduino Shield to make it work. At this point we can suggest that you rather connects a controller to an ATEM switcher which will work as the master for sending out the shading data. You might employ a cheap ATEM switcher for only this purpose.
