ABSTRACT:
A system, module and method is provided for metadata extraction and re-insertion. A module has a first input for receiving a compressed digital media stream having metadata such as DPI cues or content related information contained therein and an output for providing a first control signal including metadata information to an encoder. The metadata is extracted from the digital media stream by the module and generates a control signal including the metadata. The encoder module re-encodes the digital media contained in the digital media stream and re-inserts the metadata.
