Description

 EMI1.1 
 



   Wie in Fachkreisen allgemein bekannt, wird beim Fernsehen das zu übertragende Bild mittels einer Abtastblende, wie etwa Nipkowscheibe, Jenkinstrommel, Spiegelschraube usw., in eine Anzahl von Punkten, in der Folge Bildelemente genannt, zerlegt. Die Zerlegung geschieht mittels der an der Blende angeordneten Abtastpunkte bzw. Löcher oder Spiegel. Jeder dieser Spiegel oder Punkte oder Löcher bedeutet eine   Bildz9ile.   Normalerweise wird eine Zeile nach der andern in fortlaufender Reihenfolge abgetastet. Gegenstand vorliegender Erfindung ist eine Anordnung, bei der das Abtasten ebenfalls mit eingangs besprochenen Organen vorgenommen wird, jedoch ist die   Lochanordnung   bzw.

   Punkt-oder Spiegelanordnung abweichend von denen bisher verwendeten, u. zw. so, dass die Blende nicht etwa die Zeilen von 1-30 in fortlaufender Reihenfolge abtastet, sondern etwa die Zeile 1, 5,7, 3,9, 2,   8,   10, 4 usw. bis 30 oder im Bedarfsfalle auch mehr, von rechts nach links und umgekehrt. Dieses System ergibt eine Anzahl von Chiffreschüsseln und es ist selbstverständlich, dass Sendungen dieser Art nur von demjenigen Empfänger richtig empfangen werden können, der die Sendechiffre bzw. den Schüssel zu derselben kennt und die entsprechende Abtastblende, die leicht auswechselbar sein mnss, eingesetzt hat. Der Zweck des Chiffrierens kann mannigfach sein, so wie z. B. Berichterstattung der Presse, Beobachtung, Nachrichten, Sportveranstaltungen usw. 



   PATENT-ANSPRÜCHE :
1.   Abtastvorrichtung und Chiffrieranordnung   für Fernsehzwecke, dadurch gekennzeichnet, dass einzelne Löcher bzw. Spiegel oder sonst geeignete Faktoren und Gruppen solcher die zu Abtastzwecken verwendet werden, abweichend von der sonst auf der Blende oder   Abtastorgan   vorhandenen gesetzmässigen Anordnung liegen.

 EMI1.1
 



   As is well known in specialist circles, the picture to be transmitted in television is broken down into a number of points, hereinafter referred to as picture elements, by means of a scanning diaphragm, such as a Nipkow disk, Jenkin drum, mirror screw, etc. The decomposition takes place by means of the scanning points or holes or mirrors arranged on the diaphragm. Each of these mirrors or points or holes means an image line. Normally, one line at a time is scanned in sequential order. The subject of the present invention is an arrangement in which the scanning is also carried out with the organs discussed at the beginning, but the arrangement of holes or

   Point or mirror arrangement different from those previously used, u. in such a way that the diaphragm does not scan the lines from 1-30 in consecutive order, but rather the lines 1, 5.7, 3.9, 2, 8, 10, 4, etc. to 30 or more if necessary , from right to left and vice versa. This system results in a number of cipher keys and it goes without saying that transmissions of this type can only be correctly received by the recipient who knows the transmission cipher or the key to the same and has used the corresponding scanning aperture, which must be easily exchangeable. The purpose of encryption can be many, such as B. Press coverage, observation, news, sporting events, etc.



   PATENT CLAIMS:
1. Scanning device and cipher arrangement for television purposes, characterized in that individual holes or mirrors or other suitable factors and groups of those used for scanning purposes are different from the legal arrangement otherwise present on the diaphragm or scanning element.

Claims (1)

2. Abtastblende und Chiffrieranordnung für Fernsehzwecke nach Anspruch 1, gekennzeichnet durch eine von der gesetzmässigen abweichende Anordnung der Löeher, Spiegel oder sonst geeigneten Faktoren am Bildanfange, die als Startzeichen verwendet werden kann. 2. scanning diaphragm and cipher arrangement for television purposes according to claim 1, characterized by an arrangement deviating from the lawful arrangement of the Löeher, mirror or other suitable factors at the beginning of the picture, which can be used as a start signal. 3. Abtastblende und Chiffrieranordnung nach Anspruch 1, gekennzeichnet durch eine versetzte Anordnung der Lochreihen, Spiegel oder sonst geeigneter Faktoren in Sender-und Empfangseinrichtung zum Zwecke, einen Empfang mit regelmässig angeordneten Lochreihen, Spiegel oder sonst geeigneten Faktoren unmöglich zu machen. 3. scanning diaphragm and cipher arrangement according to claim 1, characterized by an offset arrangement of the rows of holes, mirrors or other suitable factors in the transmitter and receiver device for the purpose of making reception with regularly arranged rows of holes, mirrors or other suitable factors impossible. 4. Verfahren zur Herstellung der Blenden und Abtastanordnungen nach den Ansprüchen 1 bis 3, gekennzeichnet dadurch, dass zwecks Erzielung gleicher Loehanordnungen oder sonstiger den Abtastzwecken dienenden oder für diese Zwecke geeigneten Faktoren die Blenden auf photographischem Wege hergestellt werden. **WARNUNG** Ende CLMS Feld Kannt Anfang DESC uberlappen**. 4. A method for producing the diaphragms and scanning arrangements according to claims 1 to 3, characterized in that the diaphragms are produced by photographic means in order to achieve the same hole arrangements or other factors serving the scanning purposes or suitable for these purposes. ** WARNING ** End of CLMS field may overlap beginning of DESC **.
