PROBLEM TO BE SOLVED: To easily transmit an information signal such as a multimedia information signal. SOLUTION: This data transmission system is formed at least of a transmission part (50) in a device (2) having a transmitting circuit for processing profitable data for forming an information signal train, and a reception part (51) in another device (3) having a receiving circuit for processing the transmitted information signal train. In the system, the receiving circuit is provided with a completeness authenticating means for generating the error display of transmitted information signals at least, and even when the error display appears, this means authenticates the transmitted information signal train. Thus, image data can be transmitted in a system having narrow bandwidth. The system can be applied to a GSM network. |
