1. A system for processing a video signal into a processed video signal, the video signal including an image sequence, the system comprising:

  • a pattern recognition module for detecting a region of text in the image sequence based on coding feedback data including edge detection data generated as an intermediate byproduct of;

    a decoding of the video signal, an encoding of the video signal, or a transcoding of the video signal, and generating pattern recognition data in response thereto, wherein the coding feedback data further includes shot transition data that identifies temporal segments in the image sequence corresponding to a plurality of video shots and wherein the pattern recognition module generates a text string by recognizing the text in the region of text and further generates index data that includes the text string correlated to at least one of the plurality of video shots; and

    a video codec, coupled to the pattern recognition module, that generates the processed video signal by processing the image sequence and by generating the coding feedback data including the edge detection data as the intermediate byproduct of;

    the decoding of the video signal, the encoding of the video signal, or the transcoding of the video signal.
