ABSTRACT OF THE DISCLOSURE A digital data packet transmission system especially -but not exclusively- useful in videotex transmission uses a continuous transmission carrier. Data packets are individually included in transmission blocks which are periodically transmitted, with dummy packets being used to fill the blocks, if necessary. The period of the transmission blocks are exactly equal or a little longer than the maximum length of the transmission blocks. The beginning of each transmission block has a synchronization pattern which is constituted by a "bit sync" byte followed by a "byte sync" byte. The signals (except for the synchronizing pattern) are scrambled before transmission and descrambled upon receipt and recognization of the synchronizing pattern.
