Description

Reservation recording method of TV with one tuner

The present invention relates to a reservation recording method for a TVCR having a one-tuner. In particular, when a viewer is watching a program in a preset recording program setting, the viewer displays the OSD screen for recording and reserves it again. It relates to a method for time recording of TVCR having a tuner with one tuner to determine whether to perform recording.

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.

When you want to make a reservation recording with the TVCR as above, first, if the user operates the remote control and presses the reservation recording function key, a timer that receives the corresponding control signal displays the reservation recording setting menu screen through the CRT unit of the TVCR. By operating the remote control, the recording channel, recording date, recording start time / end time, recording speed, etc. can be set through the menu screen. When the scheduled recording start time arrives after this setting is completed, the recording mode is executed until the set recording end time.

However, in the conventional reserved recording method, regardless of whether the viewer is watching the broadcast program set by the reserved recording, when the recording start time arrives, the reserved recording setter can watch the broadcast program. Even if it is not necessary, there is a problem that power is consumed by recording.

In addition, in the case of the recording mode, it is difficult to smoothly watch the broadcast because the picture quality and output sound quality of the broadcast screen deteriorate due to the driving of the deck unit.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and when the viewer is watching the program while setting a specific broadcast program, the viewer displays the OSD screen asking whether the user wants to execute the reservation recording once again. It is an object of the present invention to provide a reservation recording method of a TVCR having a one-tuner which can prevent unnecessary video recording while consuming power.

As a technical idea for achieving the object of the present invention, the process of displaying the reservation recording setup menu OSD screen by the display means when the reservation recording key is input by the remote control, and the reservation recording setting through the reservation recording setup menu OSD screen After the completion of the predetermined time elapses, a process of checking whether the current execution mode is a TV watching mode, and if it is determined that the current TV watching mode is identical, checking whether the channel set in the reserved recording and the currently watching channel match, If the channels match, an invention is provided for performing a process of displaying a message confirming whether or not a reservation recording is executed on an OSD screen, and executing a reservation recording if a reservation recording execution is selected and canceling a reservation recording if not selected.

1 is a block diagram showing the configuration of a TVCR for implementing the reservation recording 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 the broadcast program to be recorded on the scheduled recording setting menu screen, the timer 17 confirms this. After entering the standby state (S102).

At this time, if the user selects the TV viewing mode by operating the remote controller 18 to watch TV, the timer 17 checks this and continuously determines whether the channel set in the reserved recording and the channel currently being watched match ( S103, S104).

As a result of the above determination, if it is determined that the channel set in the reserved recording and the currently viewed channel do not match, the timer 17 sends a control signal to the sheath 19 and accordingly the sheath 19 controls the deck 16. Then, recording is executed at the scheduled time (S105).

On the other hand, when it is determined that the channel set by the timer 17 and the channel currently being watched match, the timer 17 controls the OSD processing unit 20 to confirm whether to execute the scheduled recording. The broadcast program matches the broadcast program being watched. Do you want to record? Yes / No "is displayed on the CRT unit 12 (S106).

At this time, when the user selects "Yes" by operating the remote controller 18, the timer 17 confirms this (S107), and sends a control signal to the sheath (19) accordingly, the sheath (19) deck portion (16) is controlled, and reservation recording proceeds normally, and if " NO " is selected, reservation recording is canceled (S108).

As can be seen from the above description, in the present invention, when the user inputs the reservation recording key by the remote controller, the reservation recording setting menu OSD screen is displayed on the display means under the control of the timer 17, wherein the user sets the reservation recording setting. When the timer 17 completes a predetermined time, the current execution mode is checked whether the TV watching mode, and if the current TV viewing mode is checked, it is checked whether the channel set in the reserved recording and the current watching channel match again. At this time, if it is confirmed that the channels match, the OSD processing unit 20 controls to display a message confirming whether or not to execute the reservation recording on the OSD screen. If the reservation recording execution is selected by the user, the reservation recording is executed. Canceling prevents unnecessary recording while consuming power Can have the effect of preventing the deterioration of the sound quality and picture quality is generated according to the progress Sikkim the recording mode when watching TV.
