CG System Overview

What are Judo Graphics (CG)?

Judo Graphics (often called CG, short for Character Generator) is the software that renders the live graphics you see on screen during judo streams.
  1. It is made up of two main parts: a controller interface (CGplay) and a rendering engine (CasparCG).
  2. It renders these visual graphics in real time.
  3. It works by receiving real-time data packets from JudoNet.
  4. It generates professional live graphics that can be utilized for further video production.
  5. The software works for both individual and team competitions.

The Two Versions of the Software

Depending on the type of tournament, the CGplay software runs in one of two modes:
  1. National Events: This version allows the operator to customize the stream with local design styles, sponsor logos, and specific judo club names.

  1. IJF Events: This version follows the official presentation standards of the International Judo Federation. It also displays advanced information like live statistics, world rankings, and real-time fan predictions.

The Added Value of the CG System

CG provides clear, practical benefits for tournament organizers and streaming teams:
  1. Consistency and Rule Compliance: It automatically handles the tournament's branding. Whether it is displaying custom event watermarks for a local competition or enforcing strict IJF presentation rules, it ensures visual details remain accurate across all mats.
  2. Built for Live Events: It processes tournament data instantly without lagging. It remains highly reliable even in high-stress environments during rapid contest switching.
  3. Scalability: The software can handle various tournament sizes, from local events to the IJF World Tour.

FAQ

  1. What exactly is Judo Graphics (CG)? CG consists of two main software components. CGplay is the controller interface that receives live contest data from JudoNet and sends commands via TCP. The CasparCG Server is the rendering engine that receives those commands, renders the professional templates, and pushes them out to a video consumer (like an NDI stream or SDI cable).
  2. Is there a difference between CG software used for National events versus IJF Events? Yes. While the CasparCG rendering engine remains the same, the CGplay controller interface is a different version for IJF events. The IJF version removes Settings with local visual customization menus (to enforce strict IJF presentation standards) and adds specialized modules (live statistics, fan predictions).
