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.
