Abstract
Apparatus, systems, methods, and articles of manufacture related to end-point media watermarking are disclosed. An example device includes a media receiver to receive a media signal, a watermark generator to generate a watermark, a trigger to activate the watermark generator to generate the watermark based on an external input, an encoder to encode the media signal with the watermark to synthesize an encoded media signal, a media output to render the encoded media signal.
Claims14
A device comprising:
- at least one memory;
- instructions in the device;
- and
- processor circuitry to execute the instructions to at least:
- activate generation of watermarks based on detection of a presence of a meter external to the device, the watermarks to be encoded in a media signal, the media signal including a plurality of channels;
- change, based on an assigned quality indicator from the meter, at least one of a channel or a combination of channels of the media signal in which the watermarks are encoded to synthesize an encoded media signal, the assigned quality indicator based on strength values of previous watermarks detected by the meter, the strength values based on amplitudes of the previous watermarks detected by the meter;
- and
- output the encoded media signal.
A non-transitory computer readable medium comprising computer readable instructions that, when executed, cause one or more processors of a media rendering device to at least:
- activate watermark generation based on detection of a presence of an external meter, the watermarks to be encoded in a media signal, the media signal including a plurality of channels;
- change, based on an assigned quality indicator from the external meter, at least one of a channel or a combination of channels of the media signal in which watermarks are encoded to synthesize an encoded media signal, the assigned quality indicator based on strength values of previous watermarks detected by the external meter, the strength values based on amplitudes of the previous watermarks detected by the external meter;
- and
- present the encoded media signal.
A method for watermarking media at a media rendering device, the method comprising:
- activating, by executing an instruction with at least one processor, generation of watermarks based on detection of a presence of a meter external to the media rendering device, the watermarks to be encoded in a media signal, the media signal including a plurality of channels;
- changing, by executing an instruction with the at least one processor, and based on an assigned quality indicator from the meter, at least one of a channel or a combination of channels of the media signal in which the watermarks are encoded to synthesize an encoded media signal, the assigned quality indicator based on strength values of previous watermarks detected by the meter, the strength values based on amplitudes of the previous watermarks detected by the meter;
- and
- outputting, by executing an instruction with the at least one processor, the encoded media signal.
