Text Channel Components

Text channel components are a type of sequence grabber channel component. A text channel component captures text for use in QuickTime movies. It is controlled by a sequence grabber component. Applications programmers will normally interact with the higher-level sequence grabber component, and do not need to read this chapter.

Text channel components make use of text digitizer components, which digitze text from particular sources, such as the closed-caption text from a video input. Text channel components abstract this level of detail, allowing the sequence grabber component to work with a stream of text without regard to its source.

You should read this chapter if you are developing a text channel component, a text digitizer, or a sequence grabber component.
