Apparatus and method for handling special windows in a display

A method for generating an image on a display, wherein said image includes one or more special windows, comprising the steps of:

• embedding special window information in a video signal comprised of a first color signal, a second color signal, and a third color signal with said first color signal including said special window information, wherein said video signal characterizes said image to be generated on said display and said first and second color signals are used to display said special window information on said display;
• extracting said special window information from said video signal;
• and
• generating a display control signal in response to said window information to enable different processing of portions of said video signal associated with said one or more special windows, wherein said different processing results in said one or more special windows being produced on said display with one or more display attributes differing from non-processed portions of said video signal.

A system for generating an image on a display, wherein said image includes one or more special windows, comprising:

• means for embedding special window information in a video signal comprised of a first color signal, a second color signal, and a third color signal with said first color signal including said special window information, wherein said video signal characterizes said image to be generated on said display and said first and second color signals are used to display said special window information on said display;
• means for extracting said special window information from said video signal;
• and
• means for generating a display control signal in response to said window information to enable different processing of portions of said video signal associated with said one or more special windows, wherein said different processing results in said one or more special windows being produced on said display with one or more display attributes differing from non-processed portions of said video signal.

A computer-readable medium comprising program instructions for generating an image comprised of one or more special windows on a display by performing the steps of:

• embedding a special window information in a video signal comprised of a first color signal, a second color signal, and a third color signal with said first color signal including said special window information, wherein said video signal characterizes said image to be generated on said display and said first and second color signals are used to display said special window information on said display;
• extracting said special window information from said video signal;
• and
• generating a display control signal in response to said window information to enable special processing of portions of said video signal associated with said one or more special windows, wherein said special processing results in said one or more special windows being produced on said display with one or more display attributes that differ from non-processed portions of said video signal.

A method for displaying an image on a display, wherein said image includes one or more special windows, comprising the steps of:

• receiving a video signal that represents said image to be generated on said display, wherein said video signal is comprised of a first color signal, a second color signal, and a third color signal with said first color signal including at least one key signal embedded therein;
• extracting said at least one key signal from said video signal;
• selectively generating a display control signal in response to said at least one key signal, wherein said display control signal indicates a target area within said one or more special windows is to be specially processed in order to display said target area with one or more display attributes that differ from non-target areas;
• and
• generating an output signal based on said video signal and the presence or absence of said display control signal, wherein said output signal produces said image including said one or more special windows on said display and said first and second color signals are used to display said at least one key signal to be displayed on said display.
