Patent attributes
A graphics verification system that handles content of a channel in a broadcast chain, partitions an on-screen view of the channel into a plurality of sections based on an overlay of a plurality of graphics on the on-screen view of the channel. The content may comprise media content and may include video, audio and/or ancillary data that is associated with any portion of a particular content. A placement of each of the overlaid plurality of graphics in the plurality of sections is determined with respect to associated content on the on-screen view of the channel. The placement is determined based on a concurrent look-up of the overlaid plurality of graphics in the plurality of sections and the associated content. The concurrent look-up is based on fingerprints or watermarks of the plurality of graphics and the associated content. One or more error parameters are detected based on the determined placement. The on-screen view of the channel is calibrated prior to multicasting of the channel, based on the one or more detected error parameters.
