Many TV studios, colleges, churches, and live production venues use Grass Valley (www
. grassva11 ey. com/products) switchers and hardware that have a built-in chroma keyer. Grass Valley licenses the use of the Ultimatte technology but has developed its own system to produce good results. The keyer is integrated into several configurations and packages, which makes for easy installation, implementation, and training.
These systems are usually installed in a modular configuration with several panels and
lined up to create an impressive console. The company also provides several other hardware and software products, as well as digital studio camcorders and robotic cameras, as shown in Figure 2.9.
