Abstract:
An image data display apparatus comprising:a terminal display unit; an NTSC display unit; a frame memory having a first port and a second port, for storing an image data; a display timing control unit for generating a terminal display timing signal and an NTSC display timing signal; a frame memory control unit for determining from which port of said frame memory said image data will be read before said image data is read out of said frame memory, such that: when a first read control signal is generated in response to the terminal display timing signal said image data is read out from said first port of said frame memory, and when a second read control signal is generated in response to the NTSC display timing signal at least a part of said image data is read out from said second port of said frame memory; a first converting unit for converting said image data read out from said first port of said frame memory into a terminal display signal such that the image data read out of said first port is displayed on said terminal display unit; and a second converting unit for converting said at least a part of said image data read out from said second port of said frame memory into an NTSC display signal such that said at least a part of said image data read out of said second port is displayed on said NTSC display unit.
