Abstract

An optical disc system provides for playback of sound and video information using two sensor systems. The signals are stored in spiral tracks, one section of the disc(s) being assigned to video information that is read by one sensing head unit (1). A separate head (2) is used to read the audio signals. ADVANTAGE - Allows commentary or voices of photographed people to be heard as pictures are shown.

Description

Nach dem Stand der Technik gibt es Laser Bildplatten Systeme, in der alle für die Bild- und Ton-Wiedergabe erforderlichen Informationen gleichzeitig in codierter Form in einer spiralförmigen Spur aufgezeichnet werden. Es ist also möglich, mit einem Abtast-System Bild und Ton gleichzeitig wiederzugeben.According to the prior art, there are laser image plates Systems in which all for image and sound reproduction required information simultaneously in coded Shape can be recorded in a spiral track. So it is possible with a scanning system and image Play sound at the same time.

Beim Photo-CD System (Kodak) wird grundsätzlich nur die Bild-Information aufgenommen und gelesen. Da für viele Anwendungen zum Bild aber auch der Ton gehört, stellt sich die Erfindung die Aufgabe, auf einen Teil der Bild- Speicherkapazität zu verzichten und anstatt dessen die Ton-Information auf der freien Fläche nachträglich aufzuzeichnen.With the Photo-CD system (Kodak) basically only that Image information recorded and read. As for many Applications to the picture but also the sound belongs the invention the task of part of the image To give up storage capacity and instead the Subsequent sound information on the free area to record.

Für die synchrone Wiedergabe von Bild und Ton werden dazu zwei Abtast-Systeme verwendet. Für das Bild=System (1) für den Ton=System (2). Anstatt den vollen Programm- Bereich der Photo-CD (3) zu nutzen, wird zum Beispiel nur die Hälfte der Photo-CD (4) für die Bild-Informations- Speicherung zur Verfügung gestellt.Two scanning systems are used for the synchronous reproduction of image and sound. For the picture = system ( 1 ) for the sound = system ( 2 ). Instead of using the full program area of the Photo CD ( 3 ), for example only half of the Photo CD ( 4 ) is made available for the image information storage.

Die freie Hälfte der Photo-CD (4) wird nachträglich mit dem Ton moduliert, so daß damit die Ton-Photo-CD (5) für eine Bild- und Ton-Wiedergabe synchron vom Player gelesen werden kann.The free half of the photo CD ( 4 ) is subsequently modulated with the sound, so that the sound photo CD ( 5 ) can be read synchronously by the player for image and sound reproduction.

Die Anordnung der Abtast-Systeme (1) und (2) ist so vor­ gesehen, daß auch vom Abtast-System (2) die Möglichkeit besteht, den ganzen Ton-Programmbereich einer normalen Musik CD (6) wiederzugeben, wie umgekehrt das Abtast- System (1) den vollen Bild-Programmbereich der Photo-CD (3).The arrangement of the sampling systems ( 1 ) and ( 2 ) is seen before that the sampling system ( 2 ) also has the possibility of reproducing the entire sound program area of a normal music CD ( 6 ), as vice versa the sampling System ( 1 ) the full image program area of the Photo CD ( 3 ).

Claims (4)

1. Ton-Photo-CD-Player zur Wiedergabe von Bild- und Ton- Informationen dadurch gekennzeichnet, daß durch Einbau eines zweiten Abtast-Systems, synchron zum Bild auch eine Ton-Information auf der Photo-CD gelesen werden kann.1. Sound Photo CD player for playing picture and sound information, characterized in that by installing a second scanning system, synchronous to the picture, sound information can also be read on the Photo CD. 2. Einrichtung nach Anspruch 1, dadurch gekennzeichnet, daß die Anordnung der beiden Abtast-Systeme es ermöglicht, getrennt Bild- oder Ton-Informationen im vollen Programm- Bereich wiederzugeben.2. Device according to claim 1, characterized in that the arrangement of the two scanning systems enables separate picture or sound information in the full program Area. 3. Einrichtung nach Anspruch 1, dadurch gekennzeichnet, daß bei Ausfall eines Abtast-Systems, die Bild-Information nach der Speicherung und im Anschluß auch die Ton- Informationswiedergabe möglich ist.3. Device according to claim 1, characterized in that if a scanning system fails, the image information after saving and then also the audio Reproduction of information is possible. 4. Einrichtung nach Anspruch 1, dadurch gekennzeichnet, daß eine Photo-CD nachträglich mit einer Ton-Information moduliert werden kann.4. Device according to claim 1, characterized in that a photo CD with sound information can be modulated.
