Graphic players represent sources of stored video data whose data can be routed through output ports to other video components. The actual temporal graphical data is represented by a sequence of graphics owned by the player. Players can also be used to represent and control external playing and recording devices such as videodisc machines, videotape recorders, and digital frame stores.
Graphic sequences are the graphic data streams played by graphic players.
Processors represent digitizers and software and hardware video effects processors that alter the incoming video data. Digitizers convert analog video input to digital video data.
Typically, data is written to a view that can display the data on a monitor.
QuickTime is the persistent storage format for video and is also supported as an interchange format. QuickTime movies need to be self-contained--the movie and its data must be in a single file.
| QuickTime movie files | ||
| A QuickTime movie file created on the Macintosh typically stores a movie in the resource fork of the file. The data for the movie can reside in the data fork of the same file, or in other files--all of the data for a movie can reside in other files, allowing several movies to share the same data. | A movie file that contains all of its movie data is called a self-contained movie file. Self-contained movie files are used to move a movie from one Macintosh to another. These self-contained movie files are the files used by the CommonPoint application system. | The Macintosh Movie Toolbox provides functions for creating movie files that contain the movie and all of its data in the data fork of a Macintosh file. This allows Macintosh applications to create self-contained movie files that can be used by other systems, such as the CommonPoint application system. |
