ABSTRACT:
In a method for storing and playback of a repertoire of fixed videotexts, in which the videotext is stored by characters in digital form in an electrical memory, the quantity of the data to be stored can be effectively reduced in that in addition to the characters, position characters are stored and that for recurring, identical character sequences of greater length, instead of the character sequence, a reference to the location of the already stored character sequence is stored. The playback of the thus compressed texts can take place without problems in real time, i.e., without noticeable delay.
