Abstract (en)
[origin: WO2007082860A1] The inventive method for the transmission of media data from a multicast service by a first apparatus to a plurality of second apparatuses is suitable for preventing reception of the media data by an unauthorized second apparatus using a security process, and has the following steps: provision of a first apparatus which can be used to provide the media data protected by a security process, provision of a third apparatus which can be used to perform the security process with the first apparatus, performance of the security process between the first apparatus and the third apparatus and, on the basis of this, interchange of at least security data between the first apparatus and the third apparatus in order to provide the media data, selection of a second apparatus which can be used to perform at least one reception process for receiving the media data, selection of a first data transmission link which can be used to couple the first apparatus and the second apparatus at least for the purpose of transmitting the media data, and performance of the reception process for receiving the provided media data using the second apparatus via the first data transmission link.
