Abstract
A set top box for use with a video signal captioning system is provided. The set top box includes a first port for receiving caption text. The set top box also includes a second port for receiving a video signal. The set top box converts the caption text from the computer into a video image. The set top box then combines the video signal from the video source with the video image. The combined signal from the set top box is transmitted as an output video signal.
