Method and apparatus for automatically optimizing insert editing in a signal recorder.

摘要

A system for the automatic edit optimization of a recording medium which is operable with a recorder such as a video tape recorder or a disc recorder utilizes the difference between signal outputs from an automatic scan tracking playback head (112) and a record head (124) to provide a difference signal indicative of the rf amplitude fluctuations caused by scene or data pattern variations of the data stored on the recording medium. A correction signal corresponding to the difference signal is stored, and used as a feedback signal to normalize the gain of a variable gain amplifier (128). <IMAGE>
