Multiple display system
First Claim
1. A multiple display system for displaying data derived internally or externally on a display formed of a plurality of display devices as a single picture screen, said multiple display system comprising:
- encoder means responsive to said data for generating a coded data signal;
a plurality of decoding means connected to said encoder means and arranged in a series from a first decoding means to a last decoding means; and
a plurality of display devices respectively corresponding to said decoding means and arranged in an array forming a single picture screen, said display devices being connected respectively to corresponding ones of said plurality of decoding means for displaying respective video signals fed thereto;
wherein;
said encoder means comprises means for inserting an identification number in a predetermined portion of said coded data signal and for transmitting said coded data signal to the first decoding means in said series;
each decoding means except the last in said series comprises means for transmitting said coded a data signal to the next decoding means in said series;
each of said decoding means comprises means for adopting the identification number transmitted to it in said coded data signal as its own;
each decoding means except the last in said series comprises means for deriving a new identification number from the identification number transmitted to it and for substituting said new identification number into said coded data signal for transmission to the next decoding means in said series; and
said plurality of decoding means respectively comprise means for extracting data with corresponding identification numbers from said data sequence supplied thereto, for converting the extracted data into decoded video signals, and for supplying said display devices with said decoded video signals.

Abstract
A multiple display system is adapted to display data in the VIDEOTEX standard on a display formed of a plurality of display devices. The system comprises an encoder for generating a code on the basis of internal or external data supplied thereto, a plurality of decoders, each of which includes a central processing unit, successively arranged in series with respect to the encoder, and a plurality of display devices provided respectively corresponding to the plurality of decoders to thereby display a large image by the plurality of display devices. The encoder inserts an identification number in a predetermined portion of a data sequence. The plurality of decoders respectively select data with corresponding identification number, convert the selected data into a video signal, and supply respective display devices with the video signal.
