Abstract
In order to reduce the multitude of data for transmitting and converting use authorizations, which are received either encoded or non-encoded together with sound and/or picture contents in signals from optional networks, it is proposed to reduce the hierarchically structured use authorization information in the form of a tree structure before transmitting it further, such that non-occupied tree branches are detected and marked as not relevant, wherein the tree branches marked as not relevant are not included during the further transmitting of the use authorization information.
Claims2
A method for transmitting use authorization information, which is received either encoded or non-encoded together with sound and/or picture contents in signals coming from optional networks, characterized in that before transmitting the information, the hierarchically structured use authorization information in the form of a tree structure is reduced in such a way that non-occupied tree branches are detected and marked as non-relevant and that during the further transmitting of the use authorization information, the tree branches marked as non-relevant are not transmitted further.
A device for transmitting use authorization information, which is received either encoded or non-encoded together with sound and/or picture contents in signals coming from optional networks, characterized in that the device is embodied in such a way that before transmitting the information, the hierarchically structured use authorization information in the form of a tree structure is reduced by detecting non-occupied tree branches and marking these as non-relevant and that during the further transmitting of the use authorization information, the tree branches marked as non-relevant are not transmitted.
