Abstract

PURPOSE: A method for controlling reservation record of TVCR is provided to see and hear a broadcasting program according to a sequency set by a user by performing a video tape as a forward fast(FF) mode by an interval of a prior program time when the prior program is recorded in the video tape. CONSTITUTION: A timer identifies as to whether a reservation record key is inputted and controls an OSD processing unit to display a set menu picture of a reservation record on a CRT unit(S100,S101). The timer identifies as to whether a record channel, a record date, a start/end time, and a record velocity of a plurality of broadcasting programs are set by a user. The timer controls a deck unit to record the set broadcasting program as a result of the identification(S103). The timer identifies as to whether a broadcasting program is prior to a next recording broadcasting program when the start time of a reservation record of the next broadcasting program is reached(S104,S105). The timer checks set information of the reservation record when the broadcasting program is prior to the next recording broadcasting program and detects the start/end time of the prior set broadcasting program(S106). A system controller controls the deck unit to perform a forward fast(FF) mode by a time of the prior set broadcasting program(S107).

Description

How to control reservation recording of TV

The present invention relates to a method of controlling a reservation recording of a TVCR. Particularly, in case of performing a reservation recording using a TVCR, when the next recording time comes after one recording is finished, the priority of the reservation recording is judged to be higher than the program to be recorded now. If there is a program in the program, the tape is fast-forwarded by the time interval of the prior broadcast program. When the tape is played when all the scheduled recordings have been completed, multiple TV shows can be watched in the order set by the user. Method for controlling a time recording of TVCR.

In general, a TVCR is an integrated TV and VCR, which are powered by a single power supply and are controlled by a SYSTEM CONTROL (SYSCON) that controls the VCR and a timer that controls the entire TVCR system. Each component is operated, and is a device used for recording and reproducing television broadcast signals, recording and reproducing other recording tapes, broadcasting recording of other channels not being watched, reserved recording, and absent recording.

That is, in the case of recording on a recording tape, an AC bias method with low noise is adopted since there is no residual magnetic field due to a bias magnetic field even in the absence of a signal, and the recording of an audio signal has a frequency range of about 20-20000 Hz. The AC bias method is performed because it is narrow and the phase relationship does not have to be so much a problem. However, the frequency modulation (FM) recording method has been adopted for recording video signals because its frequency range is wide, about 0-4 MHz, and strict phase characteristics are required to faithfully reproduce waveforms.

On the contrary, during reproduction, the recorded magnetic tape is driven while being connected to the gap of the magnetic head, and the signal read by the magnetic head is amplified and processed and reproduced through the water pipe and the speaker.

However, when a plurality of broadcast programs are reserved and recorded by the TVCR as described above, the user sets a recording order for each broadcast program. If a broadcast program set to a lower priority than the broadcast program set as a priority due to a broadcasting station is broadcasted first, the user sets the order. Regardless, there was a problem that the recording is not recorded in the order intended by the user because the subordinate broadcast program is recorded first.

The present invention is to solve the above problems, when performing the scheduled recording by using the TVCR when the next recording time after one recording is finished, the priority of the reservation recording to determine the priority of the priority recording program If there is a program, the tape is fast-forwarded by the time interval of the priority broadcast program, so that the scheduled recording control method of the TVCR is provided so that the user can watch the broadcast program in the order set by the user when the tape is played with all the reserved recordings completed. Its purpose is to.

As a technical idea for achieving the object of the present invention, the process of displaying the reservation recording setup menu OSD screen when the reservation recording key is input by the remote control, and a plurality of broadcast programs are scheduled recording through the reservation recording setup menu OSD screen If a plurality of broadcast programs are set for scheduled recording, and if one broadcasting program recording is completed, the next broadcasting scheduled recording start time arrives and then there is a broadcasting program set to be higher than the next broadcasting program to be recorded. The present invention provides a process for detecting a reservation start time / end time of a broadcast program set as a priority, and a process of performing a recording operation after fastly recording the recording tape by the broadcast program broadcast time set as a priority.

Hereinafter, with reference to the accompanying drawings, the configuration and operation of the embodiment for achieving the above object will be described.

1 is a block diagram showing the configuration of a TVCR for implementing the reservation recording control method according to the present invention.

Referring to FIG. 1, the TVCR according to the present invention includes a high frequency amplifier for amplifying a high frequency signal, which is a composite video signal received from an antenna 10, a local oscillator for supplying a signal for frequency conversion, and amplification from the high frequency amplifier. And a tuner unit 11 configured to receive a local oscillation frequency from the local input unit and a local oscillation unit and convert the intermediate oscillation frequency into an intermediate frequency so as to select a high frequency signal of a desired channel and convert it into an intermediate frequency, and the tuner unit 11. While amplifying, processing and outputting an intermediate frequency signal, which is a composite video signal, is output from the VCR Y / C IC 14 to be described later, the playback is performed from the VCR Y / C IC 14. A TV image processing IC 13 for receiving a composite video signal and outputting the composite video signal to the CRT unit 12, and a CRT unit 12 for outputting a composite video signal output from the TV image processing IC 13; .

In addition, the TVCR according to the present invention receives the composite video signal from the TV image processing IC 13, modulates the luminance signal into the FM low carrier, and converts the color signal into the low pass, while connecting to the VCR Y / C IC 14. A VCR Y / C IC 14 for applying a playback composite video signal generated by demodulating the modulated luminance signal and the color signal output from the head amplifier IC 15 to the original signal to the TV image processing IC 13; After amplifying the luminance signal and the color signal modulated from the VCR Y / C IC 14 and recording them on the video head of the deck unit 16, the signals recorded on the video head are read. A head amplifier IC 15 for amplifying and demodulating is provided.

In addition, it is connected to the remote control unit 18 and the tuner unit 11 and the TV image processing IC 13 to wirelessly apply various user's control commands to the timer 17. A timer 17 for applying a control signal to the TV image processing IC 13 and controlling the sheath 19 according to the signal and the VCR Y / C IC 14 connected to the TV image processing IC 13 according to the signal. ), A synchronization detector 21 for detecting a signal, a scissor 19 for controlling the VCR Y / C IC 14 by receiving a synchronization signal from the synchronization detector 21, and under the control of the timer 17. And a memory section 22 composed of EEPROM for storing and outputting predetermined data.

The process of the present invention implemented by the system configured as described above will be described with reference to the flowchart of FIG. 2.

First, when the user presses the reserved recording key of the remote controller 18 to reserve the desired number of broadcast programs, the corresponding control code is converted into an optical signal and applied to the remote control receiver (not shown) of the TVCR. The timer 17 receiving this signal from the light receiving unit checks whether or not the reserved recording key is input, and when it is confirmed that the timer is input, the timer 17 controls the OSD processing unit 20 to display the reserved recording setting menu screen on the CRT unit 12 ( S100, S101).

At this time, when the user operates the remote controller 18 to set the recording channel, recording date, start time / end time, recording speed, etc. of a plurality of broadcast programs on the reserved recording setting menu screen, the timer 17 checks this and then decks. The control signal is sent to the unit 16 to record the first broadcast program set in the reserved recording (S103).

When the recording is completed, the timer 17 checks this and periodically checks the start time of the scheduled recording by the next broadcast. If the check result indicates that the start time of the scheduled recording of the next broadcast has arrived, the timer 17 has a higher priority than the next broadcast program to be recorded. It is checked whether there is a broadcast program (S104, S105).

As a result of the check, if it is determined that there is a broadcast program of a higher priority than the next broadcast program to be recorded, the reservation recording setting information is checked to detect the start / end time of the broadcast program reserved for the priority (S106).

When the detection process is completed, the timer 17 sends a control signal to the sheath cone 19, and the sheath 19 controls the deck unit 16 so as to fast forward the broadcast program broadcast time set as a priority (FF). The mode is performed (S107).

When the fast forward (FF) is completed, the sheath cone 19 controls the deck unit 16 again to set the next priority, and then normally executes the recording program (S108).

As can be seen from the above description, in the present invention, when the user operates the remote controller 18 and the reservation recording key is input, the timer 17 displays the reservation recording setting menu OSD screen and at this time, displays the reservation recording setting menu OSD screen. When a plurality of broadcast programs are set for scheduled recording through the timer 17, the timer 17 confirms this, and when a plurality of broadcast programs are set for scheduled recording, the next recording is completed when one broadcast program is completed and the next broadcast scheduled recording start time arrives. If it is checked whether there is a broadcast program that is set as a higher priority than the broadcast program to be detected, after detecting the reservation start time / end time of the broadcast program that is set as the priority, the control signal is sent to the system 19 to record the tape as soon as the set broadcast time. When the tape is played while all the scheduled recordings have been completed by multiple broadcasts, It can easily watch the broadcast program in the order you set.
