Abstract

1,261,452. Digital transmission systems. ELKIS ELEKTROTECHNIKA KTSZ. 28 Feb., 1969 [28 Feb., 1968], No. 10933/69. Heading H4P. In a digital data transmission system each group of bits representing a character has a Start bit added to it, the resulting signal being passed to an encoder which delivers a signal in error-correcting form for transmission. The embodiment described employs a 5-bit group to which is added a Start bit. The 6-bit signal is encoded, resulting in a 9-bit signal which includes three check bits, one after each pair of bits. If the input of 5-bit groups fails, special 6- bit signals are generated, characterized by having the "Start" bit in the second bit position. The receiver is synchronized by use of the Start bits. A decoder corrects errors, if possible, or delivers an error-indicating signal if the error is not corrected. The decoder output is the 6-bit signal similar to that at the transmitter. After the addition of a Stop bit the character group passes to the receiver output. The start of a message is indicated by a sequence of eight of the special characters. The start is indicated if at least seven of the eight are detected and are error free.
