Abstract
A method (1) of and a device for rendering content data of a content data stream. From content data identified in the content data stream, a level of toxicity is determined (4). The level of toxicity represents a measure of authenticity of the received content data stream. Content data of the received content data stream is rendered (6) based on an aggregated level of toxicity.
Claims15
A method of rendering content data of a content data stream, said method comprising the steps of:
- receiving, by a data receiver, a content data stream,
- identifying, by an identification unit, content data of said received content data stream,
- determining, by a determination unit, a level of toxicity of said identified content data, said level of toxicity representing a measure of authenticity of said received content data stream,
- providing, by an aggregation unit, an aggregated level of toxicity from said determined level of toxicity,
- rendering, by a rendering device, content data of said received content data stream based on said aggregated level of toxicity.
The method according to any of the previous claims, wherein determining said level of toxicity comprises setting a toxicity level at one of toxic, non-toxic, and an intermediate level.
The method according to any of the previous claims, wherein determining a level of toxicity comprises evaluating identified content data against available content data, and setting said level of toxicity based on a result of said evaluation.
The method according to any of the previous claims, wherein said content data stream comprises at least one marker, said marker comprising at least one of:
- a watermark encoded in said content data;
- pilot signals embedded in said content data;
- information relating to the content data as such;
- metadata relating to the content data;
- and
- technical data relating to encoding and transmission of the content data,
- wherein identifying content data of said received content data stream comprises identifying at least one marker in said received content data stream.
The method according to any of the previous claims, wherein said steps relating to identifying content data, determining a level of toxicity, providing at least one of an aggregated level of toxicity and toxicity level threshold, and rendering content data based on said determined level of toxicity are performed in a secure hardware and/or software environment.
A device for rendering content data of a content data stream, said device comprising:
- a data receiver, arranged for receiving a content data stream,
- an identification unit, arranged for identifying content data of said received content data stream,
- a determination unit, arranged for determining a level of toxicity of said identified content data, said level of toxicity representing a measure of authenticity of said received content data stream,
- an aggregation unit, for providing an aggregated level of toxicity from said determined level of toxicity,
- a content data rendering unit, arranged for rendering content data of said received content data stream at a content reproduction device based on said aggregated level of toxicity.
