An additional information is spectrally spread and superimposed on a video signal over a plurality of fields, and the superimposed additional information is detected easily. A time code information is spectrally spread using the first spectrally spreading code string synchronous to the video signal, and the spectral spread signal of the time code information is superimposed on the video signal. An additional information is spectrally spread using the second spectrally spreading code string generated synchronously to the sync signal of the video signal and having a different period or different content corresponding to the time code information, and the spectral spread signal of the additional information is superimposed on the video signal.

Dans le système de l'invention, une information additionnelle est soumise à un étalement spectral et est superposée à un signal vidéo sur une pluralité de trames; cette information additionnelle superposée peut être détectée facilement. Un code temporel est soumis à un étalement spectral effectué au moyen de la première chaîne d'étalement spectral qui est en synchronisme avec le signal vidéo et le signal à spectre étalé du code temporel est superposé au signal vidéo. Une seconde information additionnelle est soumise à un étalement spectral effectué avec la seconde chaîne d'étalement spectral qui est engendrée en synchronisme avec le signal de synchronisation du signal vidéo et a une période différente ou un contenu différent selon le code temporel, et le signal à spectre étalé contenant cette information additionnelle est superposé au signal vidéo.
