A filter graph is composed of a collection of filters of different types. Most filters can be categorized into one of the following three types.
A source filter, which takes the data from some source, such as a file on disk, a satellite feed, an Internet server, or a VCR, and introduces it into the filter graph.
A transform filter, which takes the data, processes it, and then passes it along.
A rendering filter, which renders the data; typically this is rendered to a hardware device, but could be rendered to any location that accepts media input (such as memory or a disk file).
