A character generator, often abbreviated as CG, is a device or software that produces static or animated text (such as
crawls and
rolls) for
keying into a
video stream. Modern character generators are computer-based, and can generate graphics as well as text.In the television business in
North America, the graphics generated by character generators are also often called "Chyrons", after the
Chyron Corporation, whether or not Chyron made the character generator. Similarly, in the
United Kingdom, such graphics are often called "Astons", after
Aston Broadcast Systems. These are examples of somewhat
genericized trademarks. Even though genericized trademarks are present, it is generally known throughout the world that other character generator companies exist.
