ABSTRACT:
In a skip-field video recorder, the audio signal of every field is continuously recorded. The audio signal of each skipped video field is stored in an audio field store memory and then unloaded during the recording of the next (unskipped) video field. The unloaded audio signal is multiplexed with the current incoming audio signal and recorded therewith. Alternatively, the audio signals of both the skipped field and the unskipped field may be compressed and recorded in an extended portion of each video tape track.
