Abstract  Abstract

The invention claims a method for the transmission of media data from a multicast service by a first device to several second devices; the method is suitable for preventing reception of the media data by an unauthorized second device using a security process; the method comprises the following steps: providing a first device which can be used to provide the media data protected by a security process; providing a third device which can be used to perform the security process with the first device; performing the security process between the first device and the third device and on the basis of this; at least exchanging security data between the first device and the third device in order to provide the media data; selecting a second device which can be used to perform at least one reception process for receiving the media data; selecting a first data transmission link which can be used to couple the first device and the second device at least for the purpose of transmitting the media data and performing the reception process for receiving the provided media data using the second device via the first data transmission link.

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.
