ABSTRACT:
The secrecy of data transmitted by an image transmission apparatus can be maintained by performing encoding or decoding in conformity with identification information specifying the apparatus. The image transmission apparatus, which is for dynamically converting the image data accumulated in a memory into an arithmetic code and then transmitting the code, is so adapted that, on the sending side, an initializing table for the purpose of encoding is read out of an initializing ROM based upon an ID specifying the apparatus, and a CODEC 107 performs encoding based upon the table. The encoded data is transmitted via a CCU and is decoded on the receiving side in the same manner as encoding was performed on the sending side. As a result, the secrecy of the contents of the communication can be maintained.
