Abstract

The invention relates to a method for the generation, transmission and management of self-modifying audio-visual data. The method consists of automatically modifying the data after transmission. The transmission comprises data transmission via cable, wireless data transmission and transmission using physical storage media.

Description

METHOD FOR SELF-MODIFICATION OF AUDIO-VISUAL DATA

Subjects The presented invention comprises a method for the generation, transmission and management of self-modifying audio-visual data. The method described consists of the automatic change of the data after transmission. The transmission includes the data transmission via cable, wireless data transmission and the transmission by means of physical storage media.

State of the art

The transmission of digital image data, video and audio information raises a number of issues relating to the safeguarding of intellectual and artistic rights. Audio-visual data can be copied with readily available resources and be reproduced as desired.

The patent EP0969668 of Canon KK (Japan) describes a system for transmitting an MPEG-4 data stream, are in the information about the source of the data stream and information describing access rights, embedded. The data stream contains information about access rights of each individual object. Access rights are only granted from a central server when a request arrives, the recipient clearly identified. Information about access rights and information identifying the recipient separately and are transmitted via separate data lines.

Respect for privacy is also compromised by the light copyability and the possibility of large amounts of data over long periods to archive. The diversity of data and ease of archived audiovisual data makes it nearly impossible to track which copies of the data transmitted, cached or viewed at any given time were are in a file system or in a backup copy.

Brief summary of the invention The invention unfasst a method for automatic or conditional hasten change of audio-visual data after transmission. The audiovisual data includes digital images, digital image sequences and / or digitized sounds that may be combined with text information, cryptographic keys or program code. The change of audio-visual data by deleting individual or entire parts of the audio-visual data, the selected advertisements, by the change in the chronological order of the data or the replacement of parts of the data by other data. takes place the changes in the audio-visual information according to criteria that are determined by the viewer, the content of the data or by the producer of the audio-visual data.

A variant of the modification of the audio-visual data is the replacement of parts of the data by user-defined audio-visual data or advertisements.

The change can be controlled by a number of criteria:

• The time of day, date or day of the week. For some groups of viewers can be prevented to consume audio-visual data, which are considered not suitable for this group. • The number of views or representations of the data. Thus it can be guaranteed that audio-visual data are considered no more common with a commercial value than the price paid by the observer frequency.

• User-defined profiles. automatically change as a function of the preferences of the viewer, these profiles allow the audiovisual data.

• The origin and the timeliness of the data.

• buying habits of the viewer. • The current position or location.

The method according to the invention can be combined with appropriate cryptographic methods to increase the security against unauthorized copying.

Typical applications of the invention are:

• transmission of digital images that are copy-protected by the automatic modification or deletion after a defined viewing frequency.

• Pay TV: display adjustment of advertising spots in television programs according to user profiles with the possibility of commercial-free sequences, if certain conditions as the payment of a fee are met. • transmission of audio-visual data generated with the help of monitoring systems. Each piece of data have different priorities (warning, alarm). The data can be changed as a function of priorities in order to allow more efficient management of these data.

The invention will be explained with the help of illustrations and examples.

List of Figures

Figure 1 shows various scenarios of the automatic change of audio-visual data.

The components (1-11) of the audio-visual information represents digital images, image sequences or text information. The transmitted original data (audio visual data 1) with the parts (1-11) can be changed by removing or by the change in the chronological order of individual parts. The resulting data (audio-visual data 2) contain only the information or of interest to the viewer he is entitled for their consideration. Another variation is the addition of deleted or not represented data by advertising messages (12-14) or by user-supplied data (audio-visual data 3). The representation of the audio-visual data can also be controlled as a function of time of day. In this case, content that is not appropriate for a particular group of users may be exempted from the presentation (audio-visual data 4).

The data can also be deleted completely if certain criteria are met, such as the frequency of viewing, user-defined profiles or not suitable for the viewer content (audio visual data 5).

example 1

The automatic removal or destruction of images from an image sequence that are considered, for example for a certain age group to be unsuitable, represents a possible application of the invention In the event this application, the audiovisual data contain information that certain images as unsuitable for. identify certain viewer group. In this way can we prevent that such images or scenes of children are considered. The display of such scenes can also be controlled as a function of time of day. The automatic deletion or removal of images or displaying selected scenes can only be avoided if the viewer through appropriate access code has.

Example 2 With the same technical requirements as in Example 1, the viewing of audiovisual data against unauthorized copying can be protected. Although the unauthorized access allows viewing of certain parts of the audiovisual data, but these parts represent a section or a preview of all the data and perform the function of an advertising medium that motivates the viewer to purchase the audio-visual data as a whole. example 3

The transmission of audiovisual using wireless media and portable communication devices such as mobile phones represents a typical application of the invention. The automatic change of audiovisual data enables to limit the number of views audio-visual data to a specific number and the data then to Clear. The definition of user profiles allows the efficient handling of large amounts of data.

The limited possibilities of storing audiovisual data on portable devices also makes it necessary to remove any information automatically to relieve the user of such equipment by the repeated action of erasing unneeded data.

Claims

claims
1. Method for the automatic or conditional rush change of audio-visual data after the transmission; the change of the audio-visual
Data is:
- Delete individual parts of the audio-visual data or
- the selected advertisements, by the change in the chronological order of the data or - realizes the replacement of parts of the data by other data, said alteration is carried out according to criteria that by the viewer, the content of the data or by the producer of the audio-visual data are fixed.
2. Method as in claim 1, wherein the set of audio-visual data is deleted or destroyed if one or all of the criteria are met in claim first
3. Method as in claim 1, wherein the changes in the data take place as a function of time of day, the date or day of the week.
4. Method as in claim 1, wherein the changes in the audio-visual data carried out as a function of geographic location or place of residence.
5. Method as in claim 1, wherein the alteration of the data by the frequency of viewing or the number OCE viewing operations of the data is determined.
6. Method as in claim 1, wherein the non-displayed visual information are replaced by advertising messages or provided by the observer data.
