Title (DE) VIDEORECORDER MIT VERBESSERTER TONAUFZEICHNUNG
(EN) VIDEO RECORDER WITH IMPROVED SOUND RECORDING
(FR) MAGNETOSCOPE A ENREGISTREMENT SONORE AMELIORE
Abstract:
(DE) Es wird zusätzlich ein NICAM-Tonträger übertragen, der mit digitalen Tonsignalen moduliert ist. Aufgabe ist es, einen VHS-Videorecorder so auszubilden, daß dieser Tonträger zusätzlich zu den übrigen Signalen ohne Qualitätseinbuße aufgezeichnet werden kann. Der NICAM-Tonträger wird daher in einer tieferen Schicht (S2) mit zweiten Magnetköpfen (K2) im Frequenzmultiplex mit EM-Tonträgern (T1, T2) mit herabgesetzter Frequenz aufgezeichnet. Anwendbar insbesondere für einen S-VHS-Videorecorder mit Mehrnormen-Ton-Aufzeichnung.
(EN) A NICAM sound carrier is transmitted which is modulated with digital sound signals. The purpose is so to construct a VHS video recorder that this sound carrier can be recorded in addition to the other signals without adversely affecting the quality. The NICAM sound carrier is therefore recorded in a deeper layer (S2) with second magnetic heads (K2) in frequency multiplex with EM sound carriers (T1, T2) at lower frequency. Usable especially for an S-VHS video recorder with multi-standard sound recording.
(FR) On transfère en outre une porteuse son NICAM modulée avec des signaux sonores numériques. La tâche consiste à concevoir le magnétoscope VHS de telle façon que cette porteuse son puisse être enregistrée en plus des autres signaux sans perte de qualité. C'est pourquoi la porteuse son NICAM est enregistrée dans une couche plus profonde (S2) avec de secondes têtes magnétiques (K2) en multiplexage de fréquence avec des porteuses son à bande latérale unique à fréquence réduite. Applicable notamment à un magnétoscope S-VHS à enregistrement sonore multinormes.
