Sequence Grabber Components

Overview

This chapter discusses sequence grabber components. Sequence grabber components allow applications to obtain digitized data from external sources. Applications can then request that the sequence grabber display that data or store it in QuickTime movie files. If you are writing an application that needs to acquire data from sources external to the Macintosh computer, or if you are developing a sequence grabber channel component, you should read this chapter. If you are developing a channel component, you should also read the chapter "Sequence Grabber Channel Components."

Note that the information in this chapter is presented from the perspective of a developer of an application that uses sequence grabber components. If you are developing a sequence grabber component, your component must support the interfaces described in this chapter.
