PURPOSE:To attain high performance data transmission by discriminating the parity at reception, handling a data in a frame as another information transmission data with less frequency of occurrence and sending another information transmission data without using a transmission bit in the substantial data transmission when a transmission error code is discriminated. CONSTITUTION:A parity bit is added in a frame so as to be set as an even number (or odd number) parity at the transmission of a sampling transmission data and set to be an odd (even) parity in the case of transmission of another information transmission data. In this case of reception and of the discrimination of even (or odd) parity, the frame is processed as a frame handling a usual sampling transmission data, and in the case of discrimination of odd (or even) parity at the reception, the frame is processed as a frame handling another information transmission data with less frequency of occurrence. Thus, the data transmission is made highly sophisticated in the performance. |
