Abstract:
1. A system for communicating visual communication quality information, comprising: a feature extractor that receives visual content, a feature data embedder in communication with the feature extractor, a transmitter in communication with the feature data embedder, wherein the transmitter transmits the visual content with the embedded RR feature data, wherein the feature data embedder embeds the feature data in a second set of frames, which corresponds to the second sequence of frames, subsequent to a first set of frames from which the feature extractor extracts the feature data, the first set of frames corresponding to the first sequence of frames, wherein the feature data embedder embeds a synchronization header which specifies a relationship between the feature data embedded in the second set of frames and the first set of frame from which the feature data is extracted, and wherein the synchronization header includes a start code, a length of sequence value corresponding to a number of sequential frames in which visual quality assessment is performed, and a number of frames before a current frame that the visual quality assessment was performed.
