KR980004584A - Schedule recording control method according to the presence / absence of broadcasting signal in VCR - Google Patents

Abstract

The present invention relates to a reservation recording control method according to whether a broadcast signal is present or not in a VCR. More particularly, the present invention relates to a reservation recording control method for a reserved recording operation in a case where a broadcast signal is not received on a channel on which reservation recording is being performed, So that a silent call is often prevented from being recorded and the user can easily confirm the result of the scheduled recording. To this end, the present invention comprises a first discrimination step of judging whether reservation recording is started by checking a time; As a result of the first discrimination step, when the reserved recording time is reached, the tuning data is sent to the intermediate frequency signal processor to synchronize the broadcast signal of the reserved channel, the recording control signal is outputted to the video signal processor, the system / servo circuit is driven, A first processing step of starting the processing; A second determination step of checking a synchronization signal of the video signal processing unit to determine whether there is a broadcast signal while performing the first processing step; A third discrimination step of judging whether the reserved recording is finished by checking the reserved recording end time when there is a synchronizing signal in the second discriminating step; And a second processing step of interrupting the recording control signal with the system / servo circuit unit and controlling the OSD circuit to output a message indicating the reservation recording failure when the synchronization signal is not present in the second determination step. do.

Schedule recording control method according to the presence / absence of broadcasting signal in VCR

Since this is a trivial issue, I did not include the contents of the text.

FIG. 2 is a block diagram schematically showing a general configuration of a VCR for implementing a reserved recording control method according to the present invention; FIG.

Claims (1)

A first determination step of checking whether or not scheduled recording is started by checking the time; When the scheduled recording time reaches the designated scheduled recording time as a result of the first discrimination step, the tuning data is sent to the intermediate frequency signal processing unit to output the recording control signal to the video signal processing unit while tuning the broadcast signal of the reserved channel, A first processing step of starting recording; A second determination step of checking a synchronization detection signal of the video signal processing unit to determine whether there is a broadcast signal while performing the first processing step; A third discrimination step of judging whether or not reserved recording is finished by checking the reserved recording end time when there is a synchronous detection signal in the second discriminating step; And a second processing step of interrupting the system / servo control signal and the recording control signal when there is no synchronization detection signal in the second determination step and outputting a message indicating a reservation recording failure by outputting an OSD control signal, Wherein the VCR includes a broadcast signal and a broadcast signal. ※ Note: It is disclosed by the contents of the first application.
