The present invention relates to a method of displaying reservation information in a video cassette recorder. In particular, the video broadcasting program name is displayed together with a TV broadcasting program name when the contents of the general reservation information reserved in the video cassette recorder having a KBPS (Korea Broadcasting Program System) module are included. The present invention relates to a reservation information bisplay method in a cassette recorder.

Currently, a commonly used video cassette tape recorder (hereinafter referred to as a VCR) reads image information recorded on an image information recording surface of an information recording medium such as a video tape and outputs an image on a CRT of a television as a video signal. In addition to performing an image reproducing operation for outputting, receiving a television broadcasting signal according to a television broadcasting program of a predetermined channel, processing an image signal and an audio signal, and then recording information of a recording head such as a video tape. The video recording operation for recording the video signal and the audio signal on the image is also performed.

A VCR equipped with such a video playback function and a video recording function can be viewed through a key input operation of a key matrix provided in a remote control or a control panel of the VCR when a user wants to watch a television broadcast program of a predetermined channel broadcast in the absence of a user. When the channel number, reservation date, and reservation time of the desired television broadcasting program are set, the television broadcasting signal corresponding to the desired television broadcasting program of the predetermined channel is transmitted to the tuner built into the VCR as the set reservation date and reservation time elapse. And a reservation recording function for recording on the information recording surface of the information recording medium through the recording operation of the recording head. In the case where a television broadcasting program is scheduled to be recorded in a VCR equipped with the reservation recording function, The timer in itself reveals the correct current time In view of the problem that when the time indicated by this timer does not coincide with the current time, accurate reservation recording of the television program is impossible. When there is a key input operation for transmission, it also has a scheduled recording time check function to automatically correct the timer time of the video device to the correct current time.

And, as is well known, the video tape applied to the recording of a specific video / audio program and the reproduction of the recorded video / audio program by using magnetic properties is a hard-named 'video cassette'. The program recorded on the reel of the case and recorded on the videotape is recorded sequentially with time difference, while the reproduction of the videotape is normally performed unless a specific positioning is performed. This is done based on the recording order of a program having temporal continuity.

The VCR is extended from a conventional program for viewing a simple video / audio and is applied to, for example, a recording operation of a program to which a caption function has been added. A VCR having such a caption function is generally a program video / audio. When recording a voice, a character corresponding to the voice signal is incorporated at a specific position of the screen, and when the caption function is selected, the character is output as the caption data.

The VCR with the caption function for displaying such caption data is gradually expanding its application range. For example, program video / audio and text are provided to selectively display caption data of a language study paper using video tape. When data is recorded, the caption function can be used to improve the learning efficiency of the language.

Audio head 51 for reading audio data recorded on the video tape in the playback mode and recording the audio signal from the audio processor 54 on the video tape in the recording mode. An error column device for stabilizing driving and closeness of the bias magnetic field head and video tape, and driving for loading / unloading or playing the video tape, stopping, rewinding, rewinding, recording, pausing and discharging, etc. Tape drive mechanism 52 in charge of the video, the video head 50 or a video destination for processing image data sent from the outside Audio section 51, audio processing section 54 for processing the audio data transmitted from the outside, control means 57 for controlling the operations of each part of the VCR, and the control means 57 The video switching unit 55 and the audio switching unit 56, which are switched to the recording terminal R or the playback terminal P according to the control signal of the controller, and a key input unit used as a means for selecting various functions intended by the user. It comprises 58.

Since the general VCR configured as shown in FIG. 1 has a broadcast reservation recording function, general reservation recording (SINGLE), daily reservation recording (DAILY) and weekly reservation recording (WEEKLY) are the kinds of reservation recording functions. have.

Here, the general reservation recording method will be described as an example.

First, in order to perform the general reservation recording, the television is switched on, and then the channel of the television is switched to 3 or 4, which is a dedicated channel of the VCR, or a key input employed in the television when the video / audio terminal is connected to the television. If the current time is not set after switching the TV / video button of the means to the video state, the reservation function is not executed correctly, so make sure that the current time is correct.

Then turn on the VCR, press the TV / Video button on the front display panel of the VCR so that the VCR indicator lights up, and then insert the video tape.

Then, when the function selection button of the remote controller as the key input unit 58 shown in FIG. 2 is pressed, the multi-function / channel lamp installed on the remote controller is turned on and the screen shown in FIG. 3A is displayed on the screen of the television. Is displayed.

Next, the user turns the jog dial of the remote control shown in FIG. 2 to set the ▶ mark on the screen displayed on the screen of the television as shown in FIG. By turning and pressing the function selection button, a screen as shown in Fig. 3B is displayed.

Then, the user turns the jog dial on the remote control to move the cursor to the channel field in the screen displayed on the screen of the television to designate the channel. When the channel designation operation is completed, the user rotates the jog dial again to move the cursor to the recording speed field to record. Specify the speed, and then specify the year, month, day, start time, and end time of the scheduled recording date, and then press the function selection button on the remote control again.The first function selection screen will appear as shown in Figure 3 (A) above. Appears in the first screen of the screen 2.The character of the general reservation recording column changes to 2.The reservation is completed, then rotate the jog dial to set the number, and press the function selection button again. The screen disappears, and when the user turns off the video power, a predetermined drug indication is displayed on the function display panel of the VCR. If a scheduled recording is performed.

Here, when the state of the cursor is blinking, it means that the selection is waiting.

On the other hand, when the user executes the daily reservation recording (DAILY) or weekly reservation recording (WEEKLY) function in addition to the above-described general reservation recording (SINGLE), it is enough to perform in the same manner as the general reservation recording method (Fig. 3 (C)). And (D)].

The operation of confirming and canceling the contents reserved by the user is as follows.

For example, to check the contents reserved for the reservation recording number 1, press the function selection button on the remote control while the VCR is turned on. The screen as shown in FIG. 3E is then displayed. Accordingly, when the user rotates the jog dial to select 5.Reservation confirmation and cancellation and then turns the shuttle ring, the screen as shown in Fig. 3F is displayed. Subsequently, the user finds the reservation number using the jog dial and checks the reservation contents. In addition, the reservation contents cancellation operation is to cancel the currently displayed reservation contents when the channel clear button is pressed.

In this manner, the reservation contents confirmation and cancellation operation is performed. The reservation contents confirmation and cancellation operation is completed by pressing the function selection button.

However, in a VCR in which reservation recording dates and reservation times corresponding to a plurality of broadcast programs are reserved by the above-described general reservation recording (SINGLE), daily reservation recording (DAILY), or weekly reservation recording (WEEKLY), If the scheduled recording data is erased due to a program change or a power failure due to a power failure, or if the current time is not set, the inconvenience that the program recording operation based on the reserved data is not performed correctly occurs. .

Therefore, in order to solve such a problem, the KBPS (Korea Broadcasting Program System) method is newly adopted in recent years, and the KBPS method refers to digital recording of program reservation recording data (data containing a broadcast program name) on a television signal. It is converted into signal and inserted into any one line of VBI (Vertical Blanking Interval) and transmitted. This signal is demodulated by KBPS decoder on the receiving side to perform broadcasting program reservation recording and automatic time setting function. It means TV reservation recording method.

The function of the above KBPS method is 1. Even if the program is changed due to broadcasting station circumstances, each program is given a unique code. Therefore, if the user enters the code data without changing the time, the corresponding program is entered. Accurate scheduled recording function to record only the recording; 2. The reserved recording data preservation function which can execute the accurate reserved recording after the power failure, because the reserved recording data is stored in the memory device even in the event of power failure; 3. Automatic time setting function that automatically sets the time in the VCR set by selecting the current time information from the decoder IC in the VCR control micom when the broadcasting station standard time information is received; 4. Continuous program recording function that can easily reserve the soap opera; 5. There is a broadcasting program classification function that classifies broadcasting programs into news, drama, culture, comedy, documentary, sports, movies, and shows.

As shown in FIG. 4, the conventional KBPS module 26 for enabling such a KBPS scheme includes a video signal from a tuner (not shown) and a Y / C video signal from a video module (not shown). The first switching unit 10 for switching the output of the tuner video signal when the power off (OFF) and the switching output of the Y / C video signal when the power on (ON), and the first switching unit ( A synchronization separator 12 for separating the horizontal, vertical, and color synchronization signals from the video signal from the video signal 10, and a data slicer 14 sliced to synchronize synchronization with each of the synchronization signals separated from the synchronization separator 12. A KBPS decoder 16 for an OSD processor that decodes and synchronizes the OSD with respect to digital data from the data slicer 14, and a program ROM 18 for storing an operation program for executing the KBPS decoder 16. ), The KBPS decoder Font ROM 20 in which character data required by (16) is stored, after digital / analog conversion (DAC) 22 for converting the digital signal output from the KBPS decoder 16 into an analog signal (DAC) 22, and the DAC And a second switching unit 24 for finally outputting the video signal from 22.

In the operation of the conventional KBPS module 26 configured as described above, since the data must always be input to the KBPS decoder 16, the video signal from the tuner (not shown) in the case of power-off is switched to the first switching unit. A Y / C video signal input through 10 and passed through a video module (not shown) in the case of power-on is input. The input video signal is applied to the synchronization separator 12. The horizontal, vertical, and color synchronization signals are separated from the synchronization separator 12, and the separated synchronization signal is divided into the data slicer 14 and the KBPS decoder. It is sent to (16) to synchronize the data slicer and OSD synchronization respectively.

The digital data sliced by the data slicer 14 is decoded by the KBPS decoder 16, and the KBPS decoder 16 uses the program ROM 20 based on the sliced digital data to perform a KBPS decoding operation. The address of the image is designated, and the program ROM 20 gives the execution data corresponding to the address to the KBPS decoder 16, so that the KBPS decoder 16 operates. At this time, the KBPS decoder 16 obtains the necessary character data from the font ROM 20.

In this way, the KBPS decoder 16 completes the KBPS decoding operation under the control of the control means 59 of the VCR and sends a digital KBPS video signal to the DAC 22, and the digital signal is analogized in the DAC 22. After the conversion, it is output through the second switching unit 24.

A broadcast program general reservation recording operation in a VCR employing the KBPS module 26 as described above is as follows.

Once the function selection button (or function setting button) on the remote control is pressed, the name of each broadcasting station (e.g., A, B, C, D, ...) is displayed on the television screen. When a broadcast station name is selected, as shown in FIG. 5A, broadcast programs for each time zone of the currently selected broadcast station (for example, A broadcast station) are sequentially displayed.

Next, when the user places the cursor on the name of the program to be reserved on the displayed screen and presses a function setting button (not shown), the reserved recording information for the selected program is shown in FIG. 5 (B). As shown in the figure, each item is written according to the program characteristics.

At this time, for example, if the information displayed on the screen is played twice a week, press the number 2 key on the remote control and the number of scheduled recording will be changed continuously. If you want to cancel, press the number 0 key. If you press this button, K recording reservation is canceled. When the information displayed on the screen is to be reserved as it is, when the "K" button (not shown) installed on the remote controller is pressed, the reservation operation is terminated and the screen is switched to the broadcast screen. Here, the above K recording reservation means a recording reservation operation performed in the KBPS system.

The reservation contents confirmation and cancellation operation in the KBPS method is performed similarly to the reservation contents confirmation and cancellation operation of the above-described VCR.

As described above, in the case of the reservation recording method in the general VCR, in order to check the scheduled alarm, the user must not only check the reservation number by up / down, but also confirm the content of the reservation channel and the year, month, and date of the reservation recording. If the elapsed time since the reservation is not long since it is the day, start time, and end time, it is easy to recognize what program is the reserved content. If the elapsed time after the reservation is long, what broadcast is reserved? You do not know exactly whether it is a program.

In the case of the reservation recording method in the VCR employing the above-described KBPS module, the program name for the reservation number is displayed during the reservation number up / down operation after pressing the confirmation button (not shown) to confirm the reserved information. In this case, too, as in the above-described reservation recording method of the general VCR, there is a need to confirm while up / down the reservation number.

Accordingly, the present invention has been made in view of the above circumstances, and an object thereof is to check the reservation contents set by the general reservation mode in a video cassette recorder with a built-in KBPS module. The present invention provides a method of displaying reservation information in a video cassette recorder which makes it easier to confirm reservation contents by being displayed together with the broadcast program name.

In order to achieve the above object, a method of displaying reservation information in a video cassette recorder according to the present invention is a video cassette recorder having a built-in KBPS module and allowing a reservation recording operation by a KBPS method. A first step of, when the mode is set, the KBPS module searches for broadcast program name data for the broadcast program from the television signal based on the general reservation recording data for the broadcast program; A second step of storing broadcast program name data and general reservation recording data according to the search result; A third step of judging whether the general reservation recording mode has ended and determining whether to set a reservation contents confirmation mode when the general reservation recording mode has ended; When the reservation contents confirmation mode is set, a fourth process of displaying stored program name data and general reservation recording data on a CRT screen is performed.

According to the present invention configured as described above, if a user sets the reservation contents confirmation mode after performing a general reservation recording operation using a video cassette recorder capable of a reservation recording operation using the KBPS method, all reservation information stored up to now (each Broadcast program name by channel and time zone) is displayed.

Hereinafter, with reference to the accompanying drawings will be described the present invention in more detail.

FIG. 6 is a block diagram of a reservation information display apparatus in a video cassette recorder employed in the present invention. The same components as those described in FIGS. 1 and 4 are denoted by the same reference numerals, and description thereof will be omitted. Omit.

The memory unit 42 stores the general reservation recording data currently input under the control of the control means 57 and the data in the corresponding KBPS module 26 (that is, the data meaning the program name) under the normal reservation recording mode. Non-volatile memory, such as EEPROM.

The control means 59 controls the operation of each part of the video cassette recorder in accordance with each operation command signal input from the key input unit 58, while being stored in the memory unit 42 in the reservation contents confirmation mode assumed by the present invention. Controls the display operation of all reservation information.

An example of a device configured as described above will be described below with reference to the flowchart of FIG. 8 for a method of displaying reservation information in a biocassette recorder according to the present invention.

In the description of the embodiment of the present invention, the case where the user sets the general reservation recording mode will be described as an example.

First, as a user presses a function selection button (or function setting button) on the key input unit 58, among predetermined broadcasting station names (e.g., A, B, C, D, ...) displayed on the screen of the television. If the desired broadcast station name is selected, a screen as shown in FIG. 5A is displayed, and if a broadcast program name to be reserved is selected, a screen as shown in FIG. 5B is displayed.

In this state, the user presses a desired key among the " 0 " key, " 1 " key, and " 2 " key for the currently displayed contents, sets the number of recordings, and inputs it as general reserved recording data.

In this way, when any general reserved recording data is input, the control means 59 controls the KBPS module 26, and the KBPS module 26 broadcasts corresponding to the general reserved recording data by the operation of an internal circuit. The program name data is searched (step 80).

As a result of the search, broadcast program name data corresponding to the general reserved recording data is detected and applied to the control means 59 (step 82), and the control means 59 includes the currently reserved general reserved recording data and The corresponding program name data is stored in the memory section 42 (step 84).

Then, the control means 59 judges whether the normal reserved recording mode is released (step 86), and if the general reserved recording mode is not released, the above-described operation of inputting the general reserved recording data and the inputted general reserved recording. While the program name data detection operation corresponding to the data is controlled to continue, while the general reserved recording mode is canceled (for example, when the "K" key is pressed), the screen is switched to the preset broadcast channel screen. After the control, the flow proceeds to step 88 to determine whether the reservation contents confirmation mode is set.

As a result of the determination, when another mode (e.g., videotape playback mode, etc.) is set, the control means 59 controls the operation of the entire VCR device so that the corresponding operation is performed (step 90). When the reservation contents confirmation mode is set as the confirmation button (not shown) on the input unit 58 is pressed, the control means 59 reserves all reservation information stored in the memory unit 42 (that is, reserved). Channel, the start time of the channel, the end time of the channel, and the name of the broadcast program) are applied to the KBPS module 26 to perform OSD processing, and the OSD processed reservation information is shown in FIG. And sequentially displayed on the screen of the television (step 92). Here, during the reservation information display operation, the output of the broadcast screen may be stopped once, and the reservation information display operation may be performed while the broadcast screen is output.

If there is reservation information to be canceled while checking reservation information displayed sequentially on the screen of the television, the key input unit 58 is located after placing a cursor (i.e., a mark) on the reservation information to be canceled. You can cancel by pressing the "Clear channel" button on the screen.

In this way, after finally confirming the reservation information, the user presses a confirmation button (not shown) on the key input unit 58, and accordingly, only the broadcast screen is output under the control of the control means 59.
