<p><P>PROBLEM TO BE SOLVED: To distribute high quality images to a display in an elevator only with a simple construction work. <P>SOLUTION: An image distribution system for an elevator includes: an image output part 1 for outputting an arbitrary image with digital signals; a down-converter 2 for compressing the digital signals output from the image output part 1 and converting them into analog signals; and an up-converter 5 provided in an elevator car 6 for converting the analog signals into the digital signals, thereby restoring the compressed image signals. The down-converter 2 and up-converter 5 are connected with a coaxial cable 3. The digital signals converted and restored by the up-converter 5 are reproduced on the display 7 installed in the elevator car 6. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
