Atomic components that provide the basic building blocks for processing data. Under the WDM Stream architecture, also known as a functional device or multimedia processing driver. Each filter's capability is described in part by a number of connection points called pins. Each pin can consume, produce, or both consume and produce a data stream such as digital audio. Specialized tasks can be solved by connecting filters by way of their pins into a topology—for example, to play filtered and mixed audio. Under WDM, a filter is implemented as a kernel-mode entity that is a device object usually implemented by a kernel driver. Under ActiveMovie, a filter is a User-mode entity that is an instance of a COM object, usually implemented by a DLL.
Frames per second.
A single screen-sized image that can be displayed in sequence with other slightly different images to create animated drawings. A video frame consists of two interlaced fields of either 525 lines (NTSC) or 625 lines (PAL/SECAM), running at 30 frames per second (NTSC) or 25 frames per second (PAL/SECAM). Film runs at 24 frames per second.
