The process of correcting errors in data that may have been corrupted during transmission or in storage. Data transmissions are always subject to corruption due to errors, but in video transmissions, error correction needs to deal with the errors but not retransmit the corrupted data. Video errors are corrected using a process of forward error correction in the encoder or through error concealment techniques in the decoder.
