Abstract
In one embodiment, a command is received from a video provider at a media rendering device, the command being a command to embed a subscriber ID in at least one video frame in a video stream. A random key, k is also received from the video provider at the media rendering device. An injective transformation is invoked for k and the subscriber ID, the injective transformation generating a sequence of pairs of: near-transparent patterns and corresponding time periods. Logical blocks of the at least one video frame in the video stream are overlaid with one of the near-transparent patterns for its one of the corresponding time periods. Related apparatus, systems, and methods are also described.
