Abstract

An apparatus for recording a signal having a signal content, where the apparatus comprises a receiver for receiving the signal, a processor configured to determine rights to the signal content received with the received signal, and a recorder for recording the received signal and a signal representing the determined rights to the signal content, wherein the processor is configured to give, to right holders, individual rights to the content respecting the determined rights to the content. A user who receives the signal can give individual rights to right holders respecting the rights to the content. The given rights comprise full rights and restricted rights such as owner rights corresponding to the rights to the content received with the received signal, and user rights that allow the right holder to use, such as view, the signal content. Use of the individual rights requires a corresponding individual key.

Description

technical field [0001] The invention relates to the recording by a receiver of broadcast content, in particular digital content, such as video programs, wherein the broadcast content is protected by copyright or other rights or restrictions imposed by the broadcaster. Background technique [0002] Today, there are several ways to protect recorded digital content. There are several types of protected broadcast signals. The types to be considered here are conditional access signals such as Canal+ and signals protected by broadcast marks in the United States. When the broadcast flag is set, the signal can still be recorded by the user, but cannot be copied or broadcast. For conditional access signals, it is assumed that the signal can be recorded after decryption, but that the signal is not allowed to be further copied or distributed. This can also be more dynamic by interpreting Macrovision tags more broadly. In this case, use the Macrovision flag in the same way as the Br...
