Abstract

Special data blocks or parts of data blocks are transmitted in redundant intervals or a heading is transmitted before the corresponding data block, after a suitable time interval, and another data block is inserted. By setting suitable bit errors or a parallel mode bit, premature interruption of data reeipt of the decoder is avoided. During transmission, teletext standared control bit for separating the type of magazine transmission is transmitted with the parallel mode code word.
