Abstract
A video processing device includes a content analyzer that receives a video signal and generates content recognition data based on the video signal, wherein the content recognition data is associated with at least one timestamp included in the video signal. A metadata search device generates time-coded metadata in response to content recognition data and in accordance with the at least one time stamp. A metadata association device generates a processed video signal from the video signal, wherein the processed video signal includes the time-coded metadata.
