Challenges in the Migration of Analog Closed Captioning

For video archivists, closed captions may be a hidden asset in your collection. If you have videotape that was recorded after 1976, you may have captions. This is because of the simplicity, robustness, and interoperability of closed captions. In analog recording, captions were hard to lose. With digital recording, the opposite is true, and captions can be lost in every step of the digitization process.
