Video Compression Manager Drivers
Video compression drivers provide low-level compression, decompression, and rendering services. The algorithms used by these drivers can be hardware- or software-based. These drivers are used for the following services:
·Compressing and decompressing data
·Rendering compressed data to the display
·Handling text and custom data.
The following topics describe the interface for these drivers:
·Writing video compression, decompression, and rendering drivers
·How a driver handles the system messages for the installable-driver interface
·How a driver handles messages specific to compressing, decompressing, and rendering data
·Alphabetic reference to the messages and data structures used to write compression, decompression, and rendering drivers.
