1. A method for a mobile search-ready smart display system containing a smart display having a screen and at least one mobile device having a camera, the method comprising:

  • extracting, by a hardware processor, a plurality of video fingerprints from an ongoing content displayed on the screen, the ongoing content having video frames corresponding to the video fingerprints;

    determining, by the hardware processor, one or more representative video fingerprints of the video frames from the plurality of video fingerprints;

    generating, by the hardware processor, one or more encoded representative video fingerprints through encoding the one or more representative video fingerprints into a pixel translucency change;

    delivering, by the hardware processor, the one or more encoded representative video fingerprints via a screen-camera communication; and

    performing, by the hardware processor, the encoding of the one or more representative video fingerprints and the delivering of the one or more encoded representative video fingerprints by solving a polynomial time dynamic problem to find a value indicating a video retrieval accuracy between an error resilience and a transmission time.
