KR970050151A - Reserved recording warning device based on video tape recording time detection - Google Patents

Abstract

According to the present invention, if the recording time is set to exceed the recordable time according to the reservation recording function by recognizing the recordable time by detecting a marking code indicating the recordable time formed on the video tape in the video tape recorder, the corresponding video tape is set. Provided is a reservation recording and warning device according to the detection of a recordable time of a video tape that can warn the user of a non-recordable state.

Accordingly, the present invention provides a video tape recorder in which a reservation recording function is executed by setting a function item of a reservation channel and a reservation time according to the reservation recording mode; The tape loading mechanism 4 for loading and seating the video tape 10 to be reserved recording and the code value for the recordable time are marked by loading the video tape 10 formed as the marking code 10A. Marking code detection means (6) for detecting the code, the time detection signal for the recordable time of the loaded video tape 10 through the marking code (10A) detected by the mark code detection means (6) The tape time at the time of loading of the video tape 10 by the tape loading detecting means 8, the function setting means 12 for key setting the function items according to the weak recording mode, and the tape loading mechanism 4; Receive the time detection signal from the detecting means 8, recognize the recordable time, and make the reserved time exceed the recordable time among the function items of the reserved recording mode set by the function setting means 12. Control means 18 for controlling the non-recordable state via the video tape 10 to be displayed on the screen, and display signal processing for generating display information for displaying the non-recordable state under the control of the control means 18; It is characterized by comprising a means (19).
