Description

Es ist grundsätzlich bekannt, bei· der Übertragung von Fernsehbildern das Gesamtbild in mehrere Teilbilder aufzulösen, diese einzeln auf getrennten Kanälen zum Empfänger zu übertragen und sie dort wieder in der richtigen Weise zu vereinigen. Die vorliegende Erfindung betrifft ein solches Verfahren, welches sich auf die Übermittlung von Kinofilmbildern beschränkt.It is known in principle when transmitting of television pictures to break up the overall picture into several partial pictures, these individually to transmit them on separate channels to the receiver and to reunite them there in the correct way. The present The invention relates to such a method, which is limited to the transmission of movie images.

Erfindungsgemäß soll der auf dem Fernsehwege zu übertragende Film zunächst durch eine besondere, hier nicht näher zu beschreibende rein optisch-mechanische Einrichtung (Kopiermaschine) in der Weise umkopiert werden, wie es aus den Abb. 1 und 2 hervorgeht. According to the invention, the film to be broadcast on television should first go through a special, purely optical-mechanical device not to be described in more detail here (Copier) can be copied in the manner as shown in Figs. 1 and 2.

Abb. ι zeigt den zu übertragenden Originalfilm, dessen einzelne Bilder angenommenenfalls in jeweils drei Teilbilder aufgelöst werden sollen. Diese Zahl der Teilbilder ist hier nur als Beispiel gewählt; sie kann in der Praxis den Bedürfnissen entsprechend natürlich beliebig kleiner oder größer gewählt werden. Diese drei Teilbilder sind mit I, II, III, ferner I', II', III' usw. bezeichnet. Die Umkopierung erfolgt solcherart, daß die im Originalfilm untereinander befindlichen Teilbilder jedes Einzelbildes jeweils nebeneinander, quer zur Transporteinrichtung des Films angeordnet werden, wie dies aus Abb. 2 hervorgeht. Durch diesen Prozeß des Umkopierens entsteht so ein Film dreifacher Breite, aber von einem Drittel der Länge des Originalfilms. Der durch den Umkopierprozeß erhaltene Film wird nunmehr mit den an sich bekannten Mitteln der Fernsehtechnik so zum Empfänger übertragen, daß jeder der drei entstehenden Streifen auf einem besonderen TeIegraphierkanal übermittelt wird.Fig. Ι shows the original film to be transmitted, its individual images, if applicable should be resolved into three partial images. This number of sub-images is chosen here only as an example; in practice it can be used according to needs can of course be chosen arbitrarily smaller or larger. These three partial images are denoted by I, II, III, also I ', II', III 'etc. The copying takes place in such a way, that the partial images of each individual image located one below the other in the original film are arranged side by side, transversely to the transport device of the film, as can be seen from Fig. 2. This process of copying creates a film of three times the width, but of one Third of the length of the original film. The film obtained through the copying process now becomes the receiver with the means of television technology known per se transferred that each of the three resulting strips on a special Telegraphierkanal is transmitted.

Abb. 3 zeigt ein Ausführungsbeispiel für einen hierzu geeigneten Sender. Bei diesem wurde die Verwendung von drei Polygonspiegelrädern i, 2 und 3 zugrunde gelegt, die von einem gemeinsamen Motor 4 angetrieben werden. Die von drei Lichtquellen 5, 6 und 7 herrührenden, mit Hilfe der Spiegelräder geradlinig über die drei Bildstreifen hinweg bewegten Abtastlichtstrahlen durchsetzen das abzutastende, durch einen nicht gezeichneten Antrieb gleichförmig weiterbewegte Filmband 8 und fallen auf je eine der drei ihnen zugeordneten Photozellen 9, 10 und 11. Die Photozellenströme werden durch nicht gezeichnete Verstärker verstärkt und zum Empfänger übermittelt.Fig. 3 shows an embodiment of a suitable transmitter. With this one was based on the use of three polygon mirror wheels i, 2 and 3, the are driven by a common motor 4. That of three light sources 5, 6 and 7 originating, with the help of the mirror wheels in a straight line across the three image strips moving scanning light penetrate the to be scanned, by a not shown Drive uniformly advanced film tape 8 and fall on each of the three of them associated photocells 9, 10 and 11. The Photocell currents are amplified by amplifiers (not shown) and sent to the receiver transmitted.

Abb. 4 zeigt eine zum Empfang der Sendung geeignete Einrichtung. Es bedeutet 12 den synchron mit dem Senderantrieb umlaufenden Antriebsmotor, der ein Spiegelrad 13 trägt. Die empfangenen Bildströme werden drei Glimmlampen 14, 15 und 16 zugeleitet, deren Leuchtflächen durch ein gemeinsames Objektiv 17 über das Spiegelrad auf die Empfangsbildfläche 18 abgebildet werden. Die Anordnung der Glimmlampen ist so gewählt, daß die von den drei Lichtstrahlen beschriebenen Teilbereiche in der richtigen Reihenfolge lückenlos aneinanderschließen.Fig. 4 shows a device suitable for receiving the broadcast. It means 12 the drive motor rotating synchronously with the transmitter drive, which is a mirror wheel 13 carries. The received image streams are fed to three glow lamps 14, 15 and 16, their luminous surfaces through a common lens 17 on the mirror wheel the receiving image area 18 can be imaged. The arrangement of the glow lamps is like this chosen that the sub-areas described by the three light beams in the correct Connect the sequence without any gaps.

Es ist ohne weiteres ersichtlich, daß die 7" Abtastung des umkopierten Films und die Zusammensetzung der Teilbereiche zum Gesamtbilde auf der Empfangsseite auch in anderer Weise als in der hier geschilderten erfolgen kann, beispielsweise durch Verwendung von Nipkow-Scheiben.It is readily apparent that the 7 "scan of the copied film and the Composition of the sub-areas to the overall picture on the reception side also in other Way than can be done here, for example by using of Nipkow disks.
