11. A method of selectively supplementing main program video content with a sign language video content, comprising: at a video receiver device, receiving data representing audio and at least one 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 having a plurality of locations to accept the sign language video content; at the video receiver device, receiving a signal indicative of a selection of a first location of the plurality of locations for display of the sign language video content; and responsive to receiving the signal indicative of the selection of the first location, at a content circuit within the video receiver device, presenting in 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; responsive to a signal to view the sign language video content, disabling a video scaler; and responsive to a signal not to view the sign language video content, enabling the video scaler.

The method according to claim 11 , where the received data is ordered so that the sign language video content is received in advance of the data that encodes main program video content at the plurality of locations that are processed to accept substitution of the sign language video content.
