Abstract
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 including extracting a plurality of video fingerprints from an ongoing content displayed on the screen. The ongoing content has video frames corresponding to the video fingerprints; determining one or more representative video fingerprints of the video frames from the plurality of video fingerprints; generating one or more encoded representative video fingerprints through encoding the one or more representative video fingerprints into a pixel translucency change; and delivering the one or more encoded representative video fingerprints via a screen-camera communication. The method also includes optimizing the encoding of the one or more representative video fingerprints and the delivering of the one or more encoded representative video fingerprints to find a balance between an error resilience and transmission time.
