Abstract

The invention relates to a method for generating a television transmission signal containing additional information, comprising the following steps: a) digitization of the visual recording signal received; b) compression of the visual recording signal by a non-reversible compression method; c) decompression of the previously compressed visual recording signal; d) comparison of the visual signal thus obtained with the visual recording signal; at the same time, the microstructure of the visual recording signal eliminated during compression is detected; e) storage of digital user information and digital or digitized management information in the positions of the eliminated fine structure; at the same time, a transmission signal containing the user information is obtained; f) conversion of the digital transmission signal into an analog transmission signal. The invention also relates to a device for implementing this method, and for separating the additional information from the transmission signal.
