The CGplay controller interface (UI) is divided into the Main Control Panel at the top and the operational tabs (MEDALISTS, LOWER 3rd, and DEBUG) at the bottom. To reveal or hide the lower panels, click the button labeled
SHOW MANUAL TRIGGER / DEBUG 
located on the bottom right side of the screen.
The upper section of the UI manages both standard live graphics and advanced cloud statistics:
-
Status Indicators: The top left features the
ONLINE/OFFLINE 
indicator (verifying the CasparCG rendering connection) and the
UDP ONLINE 
indicator (verifying the active JudoNet data flow), alongside the current
DisplayMode 
on the Scoreboard.
-
CLEAR ALL 
A switch that instantly removes all active graphics from the stream. Use this cautiously.
-
Mat nr. 
The numeric selector assigns the current CG window to a designated mat. This ensures the graphics engine only reacts to data arriving from that specific tatami.
-
Contest info
The marked area shows the contest code, contest clock (including golden score), competitors, current score, and the referee.
-
Competition Name
A text field allows the operator to manually verify or override the title of the event. This text is automatically pulled into specific templates.
-
Standard Graphics Engine: Manual triggers and their accompanying auto checkboxes are provided for core visual elements:
-
TEAMS 
Displays graphics of team competitions of countries or clubs.
-
INTRO BIG 
Triggers expanded, specialized introduction graphics.
-
REF 
Displays the assigned mat referees.
-
INTRO 
Presents the competitor names, countries, and flags.
-
MAIN SCORE 
Triggers the main live scoreboard during the active contest.
-
WIN 
Triggers the animated winner announcement banner.
- Advanced statistics: This middle section controls data fetched from the external cloud:
-
MAIN: PREDICTION 
Fan Voting: This module triggers the live fan prediction graphics on the stream. The UI includes an auto template prediction checkbox, a Getdata button, and two numeric input boxes for the White and Blue competitors. These boxes display the live prediction percentages from fans voting in the Prediction League on JudoTV. You can utilize a manual override by typing percentages directly into these fields.
MAIN: VERSUS H2H / VERSUS CONTEST / VERSUS GS 
Historical Analytics: This module manages the statistical graphics that compare the two competitors.
VERSUS H2H displays the lifetime Head-to-Head win/loss record between the two competitors.
VERSUS CONTEST shows individual historical career win percentages.
VERSUS GS highlights their statistical performance in the Golden Score.
- Clicking the Getdata versus button queries the JudoBase to
fetch these official historical records. By enabling the auto versus H2H
and auto versus GS checkboxes, operators allow the system to
automatically sequence these graphics onto the stream.
Manual Contest Code Override 
A Manual Contest Code Long checkbox allows the operator to override the automated feed and force a specific contest ID into the system.
- Hidden Context Menu (Quad Preview): Right-clicking the ONLINE/OFFLINE status indicator reveals a hidden menu:
- Set quad preview channel: Opens a dialog box where the operator can enter a destination channel number (e.g., 5). This routes a miniaturized version of the active mat to that specific CasparCG/NDI channel. By sending multiple mats to the same destination channel, operators can build a multi-viewer for central monitoring.
- Clear quad channel: Removes the active mat from the quad preview routing.
Automated Sequences & Timers
Live action requires multiple graphics playing one after another (e.g., an INTRO BIG followed immediately by REF, INTRO, and MAIN SCORE). The UI offers auto checkboxes to automate sequential templates without requiring the operator to click multiple buttons. For WIN, MAIN PREDICTION, and MAIN VERSUS the UI utilizes numeric timer boxes:
- On after sec: Delays the appearance of a graphic. For example, setting the VERSUS stats to 35 ensures that once the initial INTRO sequence is triggered, the system will run a background timer and automatically push the VERSUS graphic to the live stream exactly 35 seconds later.
- Off after sec: Automatically removes a graphic after a set time. For example, the WIN graphic uses an Off after sec: 7 parameter to automatically fade out the winner template after 7 seconds.
Operational Tabs & Manual Graphics
Operator Pre-Event Checklist
Before the competition block the CG operator must complete a final validation:

Confirm the JudoManager (JM) server is running and the competition is fully set up (categories, entries, and draw completed).

Verify JudoNet and CasparCG are running properly and network connectivity is established (run a ping test).

Windows time is synced to the local time zone across JudoManager PC, JudoNet PC, and Graphics PC.

Windows updates are disabled on all computers.
The Dry Pass:
Run a full test contest before going live. Switch the test scoreboard
through all states to validate that the graphics render flawlessly.
