Claims

Means for generating a plurality of command signals including a lock mode command signal; A deck capable of driving in a mode corresponding to the plurality of command signals; The deck is driven in a mode corresponding to the supplied command signal, selectively outputs the first and second display signals when the lock mode command signal is applied, sets a lock mode that bushes the supplied command signal, and sets a preset mode. Means for releasing the locked mode; OSD generating means for outputting a text signal indicating the setting of the lock mode upon application of the first display signal; And a display means for visually discriminating the setting of the lock mode upon application of the second display signal.

A method of preventing malfunction of a video cassette recorder, the method comprising: a first step of determining an input of a command signal; Determining whether the input command signal is the lock mode command signal; A third step of determining whether the lock mode command signal is in the lock mode state; A fourth step of setting a lock mode and indicating that the lock mode is not in the lock mode as a result of the third step; A fifth step of releasing the set lock mode when in the lock mode as a result of performing the third step; A sixth step of determining whether the current command is in the lock mode when the input command signal is not the lock mode command signal; And a seventh step of ignoring the input command signal in the lock mode and driving in a mode corresponding to the command signal when the lock mode is not in the lock mode.

3. The method of claim 2, wherein after performing the third step, it is determined whether the current state is a specific mode and proceeds to the fourth step only when the specific mode is in effect.
