Abstract
Provided are devices, computer-program products, and methods related to removing redundant data associated with frames. For example, a method can include storing a plurality of reference data sets in a reference database, where a reference data set is associated with a media segment. The method can further include receiving, by a server, cue data for a frame. The cue data includes a plurality of pixel data samples from the frame, and the frame is associated with an unidentified media segment. The method can further include identifying an absence of a pixel data sample from the cue data for the frame, and matching the cue data for the frame to a reference data set. The matching can include using a previous pixel data sample from a previous frame. The previous pixel data sample corresponds to the pixel data sample absent from the frame, and the reference data set is associated with a media segment. The method can further include determining the unidentified media segment is the media segment.
