Abstract:
An image signal reproduction device connectible to a plurality of displays, said image signal reproduction device comprising:an image signal expansion processor for expanding a compressed image signal from a lower resolution to a higher resolution of said image, said image signal expansion processor converting said compressed image signal to a decompressed image signal; a display connection through which an inherent resolution of a display connectible to the display connection is transmitted from the display to the image signal reproduction device, a plurality of different inherent resolutions being capable of being transmitted via said display connection; a resolution setting processor that checks the display connection and sets a predetermined resolution lower than or equal to the transmitted inherent resolution; and an image signal reproduction circuit that controls said image signal expansion processor to expand said compressed image signal until a decompression corresponding to said predetermined resolution is reached and reproduces said image at said predetermined resolution so that each display connectible to the display connection, when connected thereto, displays said image at a predetermined resolution lower than or equal to the connected display's inherent resolution.
