SIGN LANGUAGE WINDOW USING PICTURE-IN-PICTURE

摘要

Content substitution and/or picture-in-picture technology is used to provide a sign language window that provides a sign language interpretation of audio content in main program audio/video content. The sign language window can be selectively disabled by a user that does not wish to view the sign language video. Also, in some implementations, the user can move the sign language window to a desired location on the display. The desired location may be one of a plurality of pre-defined display locations. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.

主权项

1. An apparatus for selectively supplementing main program video content with a sign language translation, comprising:
a video receiver device configured to receive data representing audio/video (A/V) content as a part of main program content having a first packet identifier (PID); the video receiver device being further configured to receive sign language video content data representing a sign language interpretation of the audio content having a second PID; a user interface forming a part of the video receiver device, configured to produce a signal indicative of a user enabling or disabling the display of the sign language video content; a picture-in-picture (PIP) circuit configured to selectively generate a display of a picture-in-picture window overlaying the main program content with the sign language video content; a video scaler configured to selectively down-scale an input signal to a size of the PIP window; a processor configured to control the PIP circuit and the video scaler; where responsive to the signal indicative of the user enabling display of the sign language video in the PIP window, disable the video scaler and enable the PIP circuit; and where responsive to the signal indicative of the user disabling display of the sign language video in the PIP window, disable the PIP circuit.
