Abstract
Abstract The invention relates to a method of providing a video tape with an identification code and of reading this code. An encoder is used to record the identification code in information-free parts of blanking intervals and a decoder is used to separate the code from the signal during playback. Coding is performed digitally. After separation from the signal, the identification code is indicated on a display or on the screen. <IMAGE>
