Description

Die Erfindung betrifft ein Übertragungssystem für Stereo-Tonprogramm-Übertragung, bei dem im Primärgruppenkanal eines Trägerfrequenzfernsprechsystems jeweils zwei Einseitenband-Tonfrequenzbänder ohne Träger derart übertragen sind, daß das eine Tonfrequenzband in Kehr- und das andere Tonfrequenzband in Regellage übertragen ist, und bei dem die beiden Tonfrequenzbänder symmetrisch zur Mitte des Primärgruppenkanals liegen.The invention relates to a transmission system for stereo sound program transmission in which in the primary group channel of a carrier frequency telephone system, two single sideband audio frequency bands each are transmitted without a carrier in such a way that one audio frequency band is in reverse and the other audio frequency band is transmitted in the normal position, and in which the two audio frequency bands are symmetrical to Lie in the middle of the primary group channel.

Aufgabe der vorliegenden Erfindung ist es, ein derartiges Stereo-Tonprogramm-Übertragungssystem dahingehend noch weiter zu verbessern, daß das durch ίο die beiden Tonfrequenzbänder belegte Bard eines Primärgruppenkanals besser genutzt wird.The object of the present invention is to provide such a stereo sound program transmission system to this effect To improve even further, that the Bard occupied by ίο the two audio frequency bands one Primary group channel is better used.

Gemäß der Erfindung wird das Übertragungssystem derart ausgebildet, daß in dem verbleibenden Frequenzband der Primärgruppe weitere Kanäle zur Übertragung von Gesprächs-, Ton-, Daten-, Pilotoder sonstigen Hilfssignalen eingerichtet sind.According to the invention, the transmission system is designed such that in the remaining Frequency band of the primary group further channels for the transmission of conversation, sound, data, pilot or other auxiliary signals are set up.

Diese Signale können dabei in der NF-Lage, in einer der Zwischenfrequenzlagen oder in der Übertragungslage zugesetzt werden.These signals can be in the LF position, in one of the intermediate frequency positions or in the transmission position can be added.

ao Pilot- bzw. Hilfssignale lassen sich zur Überwachung und/oder Regelung der Streckenrestdämpfung verwenden. Sie können auch für die bei der Stereo-Übertragung notwendige Synchronisation bei der Demodulation unter optimaler Ausnützung des zur Veras fügung stehenden Frequenzbandes eingesetzt werden. Auch die durch Frequenzfehler der Trägergeneratoren verursachten Frequenzverwerfungen lassen sich unter Verwendung derartiger Signale korrigieren. Eine weitere Anwendungsmöglichkeit besteht darin, daß bei Verwendung eines Kompanders Presser und Dehner in eine richtige Zusammenarbeit zueinander gebracht werden.ao pilot or auxiliary signals can be used for monitoring and / or use control of the residual path attenuation. You can also use it for stereo broadcasting necessary synchronization for demodulation with optimal use of the Veras related frequency band can be used. Also due to frequency errors in the carrier generators Frequency distortions caused can be corrected using such signals. Another possible application is that when using a compander presser and Dehner can be brought into a proper cooperation with one another.
