Abstract:
An example method comprises receiving, at a first digital device, video data, scanning video content of the video data for visual transitions within the video content between consecutive frames of the video data, each transition indicating significant visual transitions relative to other frames of the video data, timestamping each visual transition and create a first set of temporal video fingerprints, identifying items of metadata to be associated with the video data, identifying a location within the video data using the temporal video fingerprints for the identified items of metadata, generating a metadata index identifying each item of metadata and a location for each item of metadata relative to the video data using at least one of the temporal video fingerprints, and transmitting, at the first digital device, the video data, the first set of temporal video fingerprints, and the metadata index to a different digital device.
