Drop-out compensator sample-and-hold technique for in-house use. Dedicated drop-out compensators were eventually superseded by the incorporation of drop-out compensation functionality into timebase correctors based on analog-to-digital conversion and digital line stores. The advent of compressed digital video systems finally eliminated the need for line-based drop-out compensators. Most low-level media errors, such as those caused by tape damage or imperfections, are now dealt with by forward error correction techniques, and those which overwhelm the FEC layer are typically too severe to remedy using simple line-based error concealment techniques, because damage to the compressed bitstream will often damage large parts of the video image.
