Abstract
Methods and systems for closed caption processing are described. In an embodiment, a source signal may be accessed. The source signal may include a video signal and closed caption information embedded within the video signal. The closed caption information may be extracted from the source signal. A content request may be received over a network from an access device. A caption setting associated with the access device may be accessed. The video signal may be provided in a video stream over the network to the access device. The closed caption information may be provided over the network in a caption stream in accordance with accessing of the caption setting. Additional systems and methods are disclosed.
