10. The apparatus according to claim 1 , where the main video program content and the sign language video content comprises one of streamed data, a data file and a packaged medium containing a data file.
1. An apparatus for selectively supplementing main program video content with a sign language video content, comprising: a video receiver device configured to receive data representing audio and a frame of video content, the data having a plurality of packet identifiers (PIDs) where a first PID is associated with main program video content, and where a second PID is associated with sign language video content; where the main program video content comprises frames of video content in which a plurality of locations are processed to accept substitution of the sign language video content; a user interface forming a part of the video receiver device, configured to produce a signal indicative of selection of a first location of the plurality of locations for display of the sign language video content; and a content circuit forming a part of the video receiver device; where responsive to the signal indicative of the selection, the content circuit is configured to present at the first location the sign language video content to produce a video frame having a sub-frame containing the sign language video content at the first location; at least one scaler to re-scale video information, wherein the video receiver device is configured to, responsive to a signal to view the sign language video content, enable a picture-in-picture (PIP) circuit, the video receiver device also being configured to disable the video scaler when the PIP circuit is enabled, and wherein the video receiver device is configured to, responsive to a signal not to view the sign language video content, disable the picture-in-picture (PIP) circuit and enable the video scaler.
