1. A computing system comprising:
a processor; and
at least one memory storing instructions that, when executed by the processor, cause the computing system to perform operations comprising:
accessing a media signature associated with media presented by a media device;
comparing the media signature to a reference signature associated with a watermark decoded from the media presented by the media device; and
determining that the media was live or time-shifted when presented by the media device based on the comparison of the media signature with the reference signature.
