PURPOSE:To realize the synchronization of a monitor signal without making the data redundant, by securing the difference with a certain relation for the contents between the 1st and 2nd continuous transmissions of the firce continuous transmission data of a frame. CONSTITUTION:For a data group whose transmitting system of a monitor signal is identical with the constant cyclic double collation, the 8-bit 10 of the 2nd continuous transmission of the first double continuous transmission data of a frame is formed by giving an operation to the 1st continuous transmission 8-bit 9. Each data 8-bit forms a character during the P-S conversion with addition of a start bit 2, a parity bit 3 and a stop bit 2-bit 4. The characters including data 9 and 10 are eliminated, and the same character has a double continuous transmission system that continues twice. The data 9 and 10 are handled as the synchronous codes, and the difference of data is checked at the receiver side between the 1st and 2nd continuous transmissions. Thus a synchronous code is detected. |
