Provision of marked data content to user devices of a communications network

摘要

The invention refers to a method to be used in a telecommunication network for providing individually marked digital signals (S1, S2) to be transmitted to a plurality of recipient user devices (UE1, UE2), wherein a content digital signal (SO) is received together with one or a plurality of mark signals (M1, M2), and wherein an individually marked signal (S1, S2) to be provided to one of the user devices (UE1, UE2) is generated by combining the content signal (SO) with one or a plurality of mark signals (M1, M2). The invention further refers to a program and to devices for performing the method.

1. A method implemented by a device in a network, the network providing individually marked digital signals to be transmitted to a plurality of recipient user devices, the method comprising:
receiving a content digital signal and one or a plurality of mark signals, and generating an individually marked signal to be provided to one of the user devices by combining the content digital signal with the one or a plurality of mark signals, wherein combining the content signal with the one or a plurality of mark signals is performed according to a layered coding scheme, wherein the content signal is encoded into one or more layers included in a set of layers and the one or a plurality of mark signals are each encoded into one or more other layers in the set of layers, and wherein the content signal and the one or a plurality of mark signals are obtained by separately decoding each of the layers in the set of layers.
