Abstract
A method for financing multimedia content through advertising includes playing back advertising blocks between uses of the content so to finance use of the content by the advertising. Code elements of a key are embedded in predefined locations in the advertising blocks, the key being configured for decryption of the content that follows. The embedded code elements are scanned and collected during the playback of the advertising blocks. The code elements are linked schematically to form the key. The content is encrypted using the key so that a use of the content depends on at least one of a subset of the code elements determined by the advertiser and the key.
Claims20
A method for financing multimedia content through advertising, comprising:
- playing back advertising blocks between uses of the content so to finance use of the content by the advertising;
- variably selecting predefined locations for embedding code elements of a key in the advertising blocks, the key being configured for decryption of the content that follows;
- embedding the code elements in the variably selected predefined locations;
- scanning and collecting the embedded code elements during the playing back of the advertising blocks;
- linking the code elements schematically to form the key;
- encrypting the content using the key so that a use of the content depends on at least one of a subset of the code elements determined by the advertiser and the key.
A device for financing multimedia content through advertising, comprising:
- a terminal configured to play back advertising blocks between uses of the content, the advertising blocks being stored or transmitted;
- a decryption device configured to control collection of code elements of a key, the key being configured for decryption of the content that follows, the code elements being embedded in variably selected predefined locations in the advertising blocks;
- and
- a blocking circuit connected to the decryption device and configured to release the content only if the advertising blocks are fully played back.
