Stand der TechnikState of the art
Die Übertragung digitaler Bilddaten, Videosequenzen und Audioinformationen wirft eine Reihe von Problemen bezüglich der Wahrung intellektueller und künstlerischer Rechte auf. Audio-visuelle Daten können mit einfach erhältlichen Mitteln kopiert werden und beliebig vervielfältigt werden.The transmission of digital image data, video sequences and audio information poses a number of problems relating to the protection of intellectual and artistic rights. Audio-visual data can be copied using readily available means and reproduced as required.
Das Patent EP0969668 von CANON KK (Japan) beschreibt ein System für die Übertragung eines MPEG-4 Datenstroms, bei dem Informationen über die Quelle des Datenstroms und Informationen, welche Zugriffsrechte beschreiben, eingebettet sind. Der Datenstrom enthält Informationen über Zugriffsrechte jedes einzelnen Objekts. Zugriffsrechte werden von einem zentralen Server nur dann erteilt, wenn eine Anfrage, die den Empfänger eindeutig identifiziert eintrifft. Informationen über Zugriffsrechte und Informationen, die den Empfänger identifizieren sind getrennt und werden über getrennte Datenleitungen übertragen.Patent EP0969668 from CANON KK (Japan) describes a system for the transmission of an MPEG-4 data stream in which information about the source of the data stream and information describing access rights are embedded. The data stream contains information about access rights for each individual object. Access rights are only granted by a central server when a request that clearly identifies the recipient arrives. Access rights information and information identifying the recipient are separated and are transmitted over separate data lines.
Die Wahrung der Privatsphäre ist ebenfalls gefährdet durch die leichte Kopierbarkeit und die Möglichkeit, grosse Datenmengen über lange Zeiträume zu archivieren. Die Vielfältigkeit der Daten und die einfache Archivierbarkeit von audiovisuellen Daten macht es nahezu unmöglich, nachzuvollziehen, welche Kopien der Daten, die zu einem bestimmten Zeitpunkt übertragen, zwischengespeichert oder betrachtet wurden sich in einem Dateisystem oder in einer Sicherheitskopie befinden.The protection of privacy is also endangered by the ease of copying and the ability to archive large amounts of data over long periods of time. The variety of the data and the easy archivability of audiovisual data makes it almost impossible to understand which copies of the data transmitted at a particular point in time were cached or viewed in a file system or in a backup copy.
Kürze Zusammenfassung der Erfindung Die Erfindung unfasst eine Methode für die automatische oder konditioneile Veränderung von audio-visuellen Daten nach der Übertragung. Die audiovisuellen Daten umfassen digitale Bilder, digitale Bildsequenzen und/oder digitalisierte Töne die eventuell mit Textinformationen, kryptografische Schlüssel oder Programmcode kombiniert sind. Die Veränderung der audio-visuellen Daten erfolgt durch Löschen einzelner oder gesamter Teile der audio-visuellen Daten, das selektierte Anzeigen, durch die Änderung der chronologischen Reihenfolge der Daten oder das Ersetzen von Teilen der Daten durch andere Daten. Die Veränderungen der audio-visuellen Informationen erfolgt nach Kriterien, die durch den Betrachter, den Inhalt der Daten oder durch den Erzeuger der audio-visuellen Daten festgelegt sind.Summary of the Invention The invention includes a method for automatically or conditionally changing audio-visual data after transmission. The audiovisual data include digital images, digital image sequences and / or digitized sounds that may be combined with text information, cryptographic keys or program code. The change in the audio-visual data is carried out by deleting individual or entire parts of the audio-visual data, the selected display, by changing the chronological order of the data or by replacing parts of the data with other data. The changes to the audio-visual information take place according to criteria which are determined by the viewer, the content of the data or by the producer of the audio-visual data.
Eine Variante der Modifizierung der audio-visuellen Daten ist das Ersetzen von Teilen der Daten durch benutzer-definierte audio-visuelle Daten oder Werbemitteilungen.A variant of the modification of the audio-visual data is the replacement of parts of the data with user-defined audio-visual data or advertising messages.
Die Veränderung kann von einer Reihe von Kriterien gesteuert werden:The change can be controlled by a number of criteria:
• Die Tageszeit, das Datum oder der Wochentag. Damit können bestimmte Gruppen von Betrachtern daran gehindert werden, audio-visuelle Daten zu konsumieren, die als nicht geeignet für diese Gruppe betrachtet werden. • Die Anzahl der Betrachtungen oder Darstellungen der Daten. Damit kann garantiert werden, dass audio-visuelle Daten mit einem kommerziellen Wert nicht häufiger betrachtet werden als mit der vom Betrachter bezahlten Häufigkeit.• The time of day, the date or the day of the week. This can prevent certain groups of viewers from consuming audio-visual data that are considered unsuitable for this group. • The number of views or representations of the data. This guarantees that audio-visual data with a commercial value will not be viewed more often than the frequency paid by the viewer.
• Benutzer-definierte Profile. Diese Profile erlauben es die audiovisuellen Daten automatisch als Funktion der Präferenzen des Betrachters zu verändern.• User-defined profiles. These profiles allow the audiovisual data to be changed automatically as a function of the viewer's preferences.
• Die Entstehungszeit und die Aktualität der Daten.• The time of origin and the timeliness of the data.
• Kaufgewohnheiten des Betrachters. • Die geographische Position oder der Aufenthaltsort.• The viewer's buying habits. • The geographic position or location.
Die Methode gemäss der Erfindung kann mit geeigneten kryptografischen Verfahren kombiniert werden, um die Sicherheit gegenüber nicht autorisiertem Kopieren zu erhöhen.The method according to the invention can be combined with suitable cryptographic methods in order to increase the security against unauthorized copying.
Typische Anwendungsgebiete der Erfindung sind:Typical areas of application of the invention are:
• Übertragung von digitalen Bildern, die durch die automatische Veränderung oder Löschung nach einer definierten Betrachtungshäufigkeit kopiergeschützt sind.• Transfer of digital images that are copy-protected by automatic modification or deletion after a defined viewing frequency.
• Pay-TV: Anpassung der Werbesequenzen in Fernsehsendungen gemäss Benutzerprofilen mit der Möglichkeit werbefreie Sequenzen anzuzeigen, wenn bestimmte Konditionen wie die Bezahlung einer Gebühr erfüllt sind. • Übertragung von audio-visuellen Daten, die mit Hilfe von Überwachungssystemen erzeugt werden. Die einzelnen Teile dieser Daten haben unterschiedliche Prioritäten (Warnung, Alarm). Die Daten können als Funktion der Prioritäten verändert werden, um eine effizientere Verwaltung dieser Daten zu ermöglichen.• Pay-TV: Adjustment of advertising sequences in television programs according to user profiles with the option of displaying ad-free sequences if certain conditions such as the payment of a fee are met. • Transmission of audio-visual data generated with the aid of surveillance systems. The individual parts of this data have different priorities (warning, alarm). The data can be changed as a function of priorities to enable more efficient management of this data.
Die Erfindung wird mit Hilfe von Abbildungen und Beispiele erklärt werden.The invention will be explained with the aid of figures and examples.
Liste der AbbildungenList of pictures
Abbildung 1 zeigt verschiedene Szenarien der automatischen Veränderung von audio-visuellen Daten.Figure 1 shows various scenarios for the automatic modification of audio-visual data.
Die Komponenten (1-11) der audio-visuellen Informationen repräsentieren digitale Bilder, Bildsequenzen oder Textinformationen. Die übertragenen Originaldaten (Audio-visuelle Daten 1) mit den Teilen (1-11) werden durch Entfernen oder durch die Änderung der chronologischen Reihenfolge von einzelnen Teilen verändert. Die resultierenden Daten (Audio-visuelle Daten 2) enthalten nur die Informationen, die von Interesse für den Betrachter sind oder für deren Betrachtung er berechtigt ist. Eine weitere Variante ist die Ergänzung gelöschter oder nicht dargestellter Daten durch Werbemitteilungen (12-14) oder durch vom Benutzer bereitgestellten Daten (Audio-visuelle Daten 3). Die Darstellung der audio-visuellen Daten kann ebenfalls als Funktion der Tageszeit gesteuert werden. In diesem Fall können Inhalte, die für eine bestimmte Gruppe von Benutzern nicht geeignet sind, von der Darstellung ausgenommen werden (Audio-visuelle Daten 4).The components (1-11) of the audio-visual information represent digital images, image sequences or text information. The transmitted original data (audio-visual data 1) with the parts (1-11) are changed by removing or by changing the chronological order of individual parts. The resulting data (audio-visual data 2) only contain the information that is of interest to the viewer or that he is authorized to view. Another variant is the addition of deleted or data not shown through advertising messages (12-14) or through data provided by the user (audio-visual data 3). The presentation of the audio-visual data can also be controlled as a function of the time of day. In this case, content that is not suitable for a certain group of users can be excluded from the display (audio-visual data 4).
Die Daten können auch komplett gelöscht werden, wenn gewisse Kriterien erfüllt werden wie zum Beispiel die Häufigkeit der Betrachtung, benutzerdefinierte Profile oder für den Betrachter nicht geeignete Inhalte (Audio-visuelle Daten 5).The data can also be completely deleted if certain criteria are met, such as the frequency of viewing, user-defined profiles or content unsuitable for the viewer (audio-visual data 5).
Beispiel 1example 1
Die automatische Entfernung oder Zerstörung von Bildern aus einer Bildsequenz, die zum Beispiel für eine bestimmte Altersklasse als nicht geeignet betrachtet werden, stellt eine mögliche Anwendung der Erfindung dar. Für den Fall dieser Anwendung enthalten die audiovisuellen Daten Informationen, die bestimmte Bilder als ungeeignet für eine bestimmte Betrachtergruppe kennzeichnen. Auf diese Weise lässt sich verhindern, dass solche Bilder oder Szenen von Kindern betrachtet werden. Die Anzeige von solchen Szenen kann ebenfalls als Funktion der Tageszeit gesteuert werden. Die automatische Löschung oder Entfernung von Bildern oder die Anzeige ausgewählter Szenen kann nur dann umgangen werden, wenn der Betrachter über geeignete Zugangscodes verfügt.The automatic removal or destruction of images from an image sequence which, for example, are regarded as unsuitable for a certain age group, represents a possible application of the invention. In the case of this application, the audiovisual data contain information which certain images are unsuitable for an identify a certain group of viewers. In this way it is possible to prevent such pictures or scenes from being viewed by children. The display of such scenes can also be controlled as a function of the time of day. The automatic deletion or removal of images or the display of selected scenes can only be avoided if the viewer has suitable access codes.
Beispiel 2 Mit den gleichen technischen Voraussetzungen wie in Beispiel 1 lässt sich die Betrachtung von audiovisuellen Daten vor dem unberechtigten Kopieren schützen. Der unberechtigte Zugriff ermöglicht zwar ein Betrachten von bestimmten Teilen der audiovisuellen Daten, diese Teile repräsentieren jedoch einen Ausschnitt oder eine Vorschau der gesamten Daten und übernehmen die Funktion eines Werbeträgers, der den Betrachter motiviert die audiovisuellen Daten insgesamt zu erwerben. Beispiel 3Example 2 With the same technical requirements as in example 1, the viewing of audiovisual data can be protected against unauthorized copying. The unauthorized access allows viewing certain parts of the audiovisual data, but these parts represent a section or a preview of the entire data and act as an advertising medium that motivates the viewer to acquire the audiovisual data as a whole. Example 3
Die Übertragung von audiovisuellen mit Hilfe drahtloser Medien und tragbarer Kommunikationsgeräte wie Mobiltelefonen stellt eine typische Anwendung der Erfindung dar. Die automatische Veränderung von audio-visuellen Daten ermöglicht es die Anzahl der Betrachtungen audio-visueller Daten auf eine bestimmte Anzahl zu begrenzen und die Daten anschliessend zu löschen. Die Definition von Benutzerprofilen erlaubt den effizienteren Umgang mit grossen Datenmengen.The transmission of audio-visual with the aid of wireless media and portable communication devices such as mobile telephones is a typical application of the invention. The automatic change of audio-visual data makes it possible to limit the number of views of audio-visual data to a specific number and then to close the data Clear. The definition of user profiles allows large amounts of data to be handled more efficiently.
Die begrenzten Möglichkeiten der Speicherung von audiovisuellen Daten auf tragbaren Geräten machen es ebenfalls notwendig, Informationen automatisch zu löschen, um den Benutzer solcher Geräte von der wiederholten Tätigkeit des Löschens von nicht mehr benötigten Daten zu entlasten. The limited possibilities of storing audiovisual data on portable devices also make it necessary to delete information automatically in order to relieve the user of such devices from the repeated activity of deleting data that is no longer required.
