Abstract: 1. A system for transmitting individual images which are either stationary or which move during recording, comprising a television camera (1) ; a first analogue-digital converter (2) ; a digital transmitter image repetition store (3) for the transmission of images which are not at least virtually stationary ; a transmitter buffer store (4) ; either a digital transmission channel or an analogue transmission channel (5) which is limited by a first digital-analogue converter and a second analogue-digital converter ; a digital receiver image repetition store (7) ; a receiver buffer store (6) ; a second digital-analogue converter (8) ; and a television receiver (9), characterized in that the transmitter image repetition store (7) and the receiver image repetition store consist of
