Editing of programmes and other signals in digitally coded form.

摘要

A method of editing signals such as audio frequency signals representing musical or like programmes includes representing the signal which is to be edited and another signal which is to supersede part of the first signal in similar digitally coded forms comprising discrete blocks of data separated by interblock spaces. A synchronous cross-fade of the signals is cued at an interblock space preceding the transition between the signals. A series of blocks of data representing the second signal subsequent to the point of cueing and encompassing the transition may be recorded in a store for the purpose and read out for the cross-fade.
