METHOD AND APPARATUS FOR PREPROGRAMMING A VIDEO CASSETTE RECORDER

摘要

Disclosed herein is a timer preprogramming system of a video cassette recorder, which sets up a set of preprogramming information designating an initial recording tape speed, an initial recording channel, an initial recording start time and an initial recording end time and then updates the preprogramming information wherein the initial recording end time is determined by adding a predetermined period of time to the initial recording start time. The initial recording start time is updated to adjust it to an actual start time of a desired broadcast program. Simultaneously, the initial recording end time is updated to a time determined by adding the predetermined period of time to the updated start time. Further, the video cassette recorder has a rechargeable battery which serves to save the time information and the preprogramming information stored in a memory in case of a power failure.
