Method and device for retransferring and/or for processing and/or reproducing and/or storing sound and/or image content, and device for processing and/or reproducing and/or storing sound and/or image

Abstract

The aim of the invention is to satisfy the demand of public radio and free-to-air programs in relation to non-coded processing and / or reproduction and / or storage of freely accessible contents for the final user in a uniform system in order to transfer and capture coded or non-coded sound and / or image contents. As a result, a special instruction (3) adapts user authorisation information (2) which contains the reception signal. The instruction (3) signalises at reception that the end user should dispose the sound and / or image content in a non-coded manner. User authorisation information (2) is still added even with optionally, cascaded, coded transfer of sound and image content or is logically linked by suitable measurements when they are simultaneously transferred in a physically separatedmanner from the image and / or sound content. The special instruction (3) triggers a decoding of the image and / or sound content at least at the end of the retransferring cascade during the processing and / or reproduction and / or storage of the image and / or sound content which is further transferred in the coded form.

Description

technical field [0001] The invention relates to methods and devices for rebroadcasting and processing and / or reproducing and / or storing sound and / or image content, and devices for processing and / or reproducing and / or storing sound and / or image content. Background technique [0002] Illegal copying of recorded record carriers with protected sound and / or image content using personal computer programs has given rise to a series of technical safeguards (Abwehrmassnahmen) which make illegal copying more difficult or prevent illegal copying. Unlike such copy protection systems, "Content Protection and Copy Management" (CPCM) enables the use of a record carrier of content only under certain license conditions. The basic idea of ​​a CPCM system is that, for each permitted use of its content, special signaling is predetermined, added to the image and / or sound signal and analyzed by a suitable receiver. The preconditioning (Vorstellung) of American products of image and / or sound cont...

Problems solved by technology

[0004] On the other hand, a CPCM system based solely on encryption is in principle unacceptable for public legal radio broadcasting and "Free-to-Air" radio program providers
