Sports Video Refereeing
Can 11-channel videoReferee® system be reconfigured for 6 cameras?
Depending on your system, its interface can be configured to work with the number of cameras you require.
Changing the number of cameras is done in the Slomo.tv Launcher program.
To change the number of cameras in an existing project:
-
Open Slomo.tv Launcher. Shortcut:
-
Select the project where you need to change the number of cameras and click the Edit button (
) in the project row;
-
In the opened "General" tab, change the Number of Channels according to the required number of cameras
-
Go to the "I/O Boards" tab and ensure that the device-camera connectors (cameras are marked with the
icon) correspond to the server's
physical connectors to which the cameras are connected. To facilitate this task, refer to the Connectors
Scheme in the upper right corner of the tab.
If cameras are controlled via Ethernet (VR cameras) or transmit signals via the NDI interface, also ensure they are assigned the correct IP addresses
-
Save the project: in the "Summary" tab, click the Save or Save As button
The above described a quick way to change the number of cameras, however, for significant changes, the best solution is to create a new project and configure the required settings in it.

How to rename the event buttons in videoReferee® interface?
To rename a button, enter a new name [1] in the input field and double-click the right mouse button on the button you want to rename. The length of text is limited by the size of the button.
[1] Characters entered as the name of the button should be encoded in ASCII. Symbols encoding different from the ASCII, may be displayed incorrectly on the screen.
How to rename an event in the list of events?
Created events, by default, are named Ev:. This name can be easily changed to more appropriate one. To rename the event, enter the name of the event in the name input field or select the button with the corresponding event name. Select the event, which will be renamed and double-click the right mouse button on the event status bar.
We use the videoReferee® server and need to label events and key moments and then search for marked values.
The Control-VR controller is used for quick key assignment to events.
To do this, you can switch to the event key assignment mode – press the Mode key (blue color).
In this mode, the channel keys are used to assign keys to created events.
To assign a key:
- Select the desired event from the event list.
- Press the key with the name that fits the selected event.
For example, for football, the keys can have the following values:
- Home
- Guest
- Red
- Yellow
- Goal
- Offside
- Hand
- Fight
To assign a key to an event (without switching to the key assignment mode), you can use the Alt+Ch.№ button combination.
Previously used keys will have a brighter backlight.
Subsequently, the keys can be used when searching for events – using the Search button.

What type of cable and connectors do you recommend for coaxial line installation when using Slomo.tv mini-vR-Cam and mini-GoalNetCam cameras?
For coaxial line installation, we used DRAKA HD PRO 1.0/4.8 AF cable and Neutrik NBNC75BUU11X connectors. This combination has proven reliable for transmitting 3G-SDI signal over distances up to 80 meters.
For distances exceeding 80 meters, we recommend using Blackmagic Design optical Fiber 12G optical converters.
What PoE standard do mini-vR-Cam cameras comply with? What PoE switch do you recommend?
Our mini-vR-CAM cameras fully comply with the PoE standard IEEE 802.3af. Input voltage range from 36V to 57V, isolation up to 1500V.
As a PoE switch, for example, you can use the Orient SWP-7516 POE / 2P / 2SFP PS 1GB 18 x RJ45.
Any Ethernet cable of category 5e or higher can be used.
