This conformant component accepts text streams from the read_media component, and outputs the data with timed delivery using an attached clock component. This is used for subtitle information in movie playback, or timed lyrics in audio files. The expectation is that the client will receive text buffers from the output port, and perform host-side rendering of the text information.
