The present invention relates to a reservation recording method and a reservation recording apparatus, and in particular, a reservation recording method and reservation that can input reservation information using a single screen and at the same time automatically reserve some of the necessary reservation information and reserve a program. It relates to a recording device.

In general, a video cassette recorder (hereinafter referred to as a VCR) uses a microprocessor (microcom) built into the VCR to record a broadcast program to be recorded in the absence of a user, such as a scheduled time, an end time, Set the channel, date and recording mode to cut off the power of the VCR at the scheduled start time and stop the set operation, and then record the program at the scheduled start time. In addition, recording of the program is performed when the corresponding time is reached while watching a program other than the absence.

However, such a conventional method of setting a reservation recording is to go through several processes as follows. 1) Mode setting (NORMAL, DAILY, WEEKLY), 2) Setting start time of program to reserve, 3) Setting start minute, 4) Setting end time, 5) Setting end time, 6) Speed mode Setting of the program (SL, LP, SLP), 7) setting the current year, month, date and time, and 8) setting of the channel to be watched is completed.

That is, the conventional reservation process of the program has been inconvenient to go through many steps as shown in FIG. That is, there was an inconvenience, such as each step is performed using a separate screen. And since there is no backup power inside, if the power is not supplied, the clock is reset and if the user wants to make a scheduled recording, the current time must be set every time. There was a problem with reservations that were completely different from the intended program.

In addition, since the recording amount of the program to be reserved and the amount of tape that can be recorded cannot be accurately determined, there is a problem in that the user cannot specify the recording mode and record the necessary part unavoidably even when the recording mode is specified.

Accordingly, it is an object of the present invention to provide a method for setting a reservation recording through a single screen operation without going through a complicated screen operation.

Another object of the present invention is to set up a scheduled recording through a single screen operation and at the same time to automatically set the data input in some steps to reduce the setting step by the actual user to facilitate the reservation recording settings To provide.

It is still another object of the present invention to provide a reservation recording apparatus that allows a user to make a reservation recording without setting a clock every time by installing a backup power source having a long time backup function.

It is still another object of the present invention to provide a reservation recording apparatus and a reservation recording method having a function of automatically setting a recording mode in order to prevent only a part of a reservation program from being recorded due to lack of a tape during reservation recording.

In order to achieve the above object, the reservation recording method of the present application is a reservation recording method for recording in a standard mode (SP) or a low speed mode (SLP) that is predetermined times slower than the standard mode,

An initialization checking step of checking an initialization state of the reservation recording apparatus;

A reservation mode setting determination step of determining whether to set a reservation mode after the initialization checking step;

If the reservation mode is set in the reservation mode setting determination step, inputting all reservation recording data on one screen and storing the corresponding data;

Comparing the reserved recording time of the input reserved recording data with the recordable time of the recording tape;

In the comparing step, if the recordable time of the recording tape is equal to or longer than the reserved recording time, the standard recording mode is set for performing the reserved recording in the standard mode. If the recordable time is shorter than the reserved recording time, the recording function time is the reserved time. Set a combination recording mode for performing scheduled recording by combining the standard mode and the low speed mode so that the recording time is the same or longer than the recording time. An automatic recording mode setting step of setting a slow recording mode for the recording; And

And a reservation standby mode determination step of determining whether to move to the reservation standby mode after the automatic recording mode setting step.

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

1 is a schematic diagram of a reservation recording apparatus according to the present invention. In FIG. 1, a remote transmitter (remote control) for inputting data from the outside of the reserved recording device and a key matrix provided outside of the reservation recording device are input means for inputting data, and 20 is an input means for storing reservation setting data. Memory for the control, 30 is a microcomputer to control the overall operation of the system according to the reservation recording data, 40 is a tuner for tuning the signal of the specified channel among the signals flowing through the air, 50 is a RF signal received through the tuner 40 Signal processing unit for signal processing such as demodulation, 60 is a recording unit for recording the processed signal to the recording device, 70 is an On Screen Display (On Screen Display) for generating the characters necessary for reservation recording on the screen (hereinafter referred to as OSD unit) 80 is a display (e.g., a television) for displaying a video signal and a text signal generated by an OSD, and 90 is a clock means and a clock means 90. 93 are shown on the outside of the main clock, 95 is a microprocessor 30. In the invention of the present application as being a microcomputer and to perform an operation which includes therein a microcomputer and the clock frequency divider as a clock to the sub convenience of description. In addition, 100 may use a rechargeable battery or a capacitor as a backup power source.

The reservation apparatus according to the present invention having such a configuration operates as follows.

When the user inputs a specific key through a remote transmitter (remote control) or a key matrix attached to the main body, the key input unit 10 converts the code corresponding to the input key and transmits it to the microcomputer 30. When the data is input, the microcomputer 30 determines whether the corresponding input relates to the reserved setting mode. If not, the microcomputer 30 performs a function according to the input data. The control generates the character data for inputting the reserved recording data and supplies it to the display 80 (e.g., television).

The data supplied to the display 80 is displayed on the screen with the data shown in FIG. The data displayed on the screen is for the current time and date, reservation date, channel, start time and end time, and the data composed of the screen is displayed so that each data can be input in one screen.

When the screen thus configured is displayed on the display, the cursor gumbles to receive data input at the date input position. The user inputs specific data for each location by using a remote transmitter or key matrix, and if the data indicating the date or channel is incorrectly input in the microcomputer 30, the user indicates that the data is incorrectly input or displays a warning sound. You can also raise your back.

When the user presses the reservation button after the input is completed, the data is stored in the microcom (reserved program data storage memory 20 installed in the outside of the microcomputer 30 (usable memory installed in the microcomputer)). The data stored in this way is kept constant by using the backup power even when the power is not supplied to the reserved recording device.

The microcomputer 30 checks the data indicating the scheduled recording start time from the data stored in the reserved program data storage memory 20 at regular intervals, and starts recording when the time coincides with the current time of the clock in the clock means. In order to transmit the data related to the channel among the data stored in the memory 20 to the tuner 40.

The tuner 40 receives data from the microcomputer and tunes only the frequency of the corresponding channel among various frequencies introduced through the aerial. The data tuned by the tuner 40 is input to the signal processing unit 50 and recorded in the recording unit 60 through normal signal processing such as RF demodulation. At this time, before recording, the microcomputer 60 calculates the remaining time of the tape remaining on the deck in the recording unit 60 and the recording time according to the difference between the start time and the end time among the reserved recording data stored in the memory 20. The recording mode 60 transmits the recording mode setting data at the time of the scheduled recording in which the recording mode determines any one of SP, LP, and SLP using the recording time and the recording time.

That is, in the microcomputer 30, when the recording time is 70 minutes, and the amount of recordable tape is 40 minutes, the initial 25 minutes of the tape is recorded by SP and the last 15 minutes of the tape by SLP (15 × 3 = 45 minutes). )do. Also, if you have 40 minutes to record and 10 minutes of tape remaining, start recording (30 minutes) with SLP from the beginning. At this time, the remaining amount of the tape is detected by the recording unit 60 using a known detection method using a counter or LED.

The microcomputer 30 stops the scheduled recording by sending a stop command to the recording unit 60 when the end time stored in the memory 20 is reached.

3 shows another embodiment of the reservation recording apparatus according to the present invention. In FIG. 3, the same parts as in FIG.

The difference from FIG. 3 in FIG. 3 is that a separate clock block 11 is installed instead of the clock means 90 built in or connected to the microcomputer 30, and the clock is counted in the clock block 110. The microcomputer 30 reads this and performs a clock operation. In addition, a clock count can also be normally performed using the clock of the microcomputer itself. 120 is a separate backup power supply for operating the clock block.

The reservation recording method according to the present invention applied to the apparatus having the above configuration will be described with reference to the flowcharts of FIGS. 4 and 5 as follows.

4 is a flowchart illustrating a clock preset function according to the features of the reservation recording apparatus of the present invention, which is distinguished from other existing recording reservation apparatuses, and FIG. 5 is a flowchart showing the entire process of reservation recording.

As shown in FIG. 4, the reserved recording apparatus of the present invention is characterized by a built-in clock that operates itself. Such a clock is capable of setting a time in advance before it is shipped from the factory and also by a user. It is designed to correct the problem, and it also includes a backup power supply so that it can be operated even when the external power of the reserved recording device is cut off.

Therefore, when an operator inputs a specific key using a key matrix attached to a remote transmitter or a main body in a factory or the like, the microcomputer 30 receives data through the input unit 10 to determine whether the corresponding key is a key input for a clock set. (Step 210). If the input key is not related to the clock set, it is determined whether the input key is a key input for executing another mode (step 220). If the key input designates a specific mode, the designated mode is performed (step 230). If the key input is not related to mode execution, the process returns to step 210 again.

If the key input is related to the clock set in operation 210, the clock set process is performed in operation 240. At this time, the clock set processing means a process of setting the time of the clock installed in the reserved recording device as the current time. When the clock set is processed in step 240, since the reserved recording device is shipped from the factory, the power cord is unplugged. Therefore, in order to purchase the reserved recording device while the clock is set, a constant power must be continuously supplied to the clock. In step 250, the microcomputer detects whether the current power supply is in the blackout state. If it is not the power failure state, since power is still supplied from the outside, the process returns to step 250 and continuously monitors the detection of the power failure.

However, if a power failure is detected in operation 250, the power cord is unplugged by an operator, and thus, the apparatus enters the backup mode (operation 260) and the apparatus is shipped from the factory. By shifting to the backup mode as described above, the microcomputer 30 operates in a low current consumption state so that the microcomputer 30 can continue the clock operation using the backup power supplies 100 and 120.

Although the clock preset process shown in FIG. 4 was initially described as an example where the product is shipped from the factory, it can be set as the same process at any time by the user using the recording reservation apparatus. 5 is a flowchart illustrating an actual reservation recording process, in steps 310 to 320, an initialization check step for checking whether the device is initialized, steps 330 to 490, a reservation data input and storage step, and 500 The step is an automatic recording setup step and the steps 510 to 530 represent the reservation standby mode step. Each of these steps is described in more detail as follows.

In step 310, since the reserved recording device is in a factory mode or is in a state where the power is cut off, the backup recording device is in a backup mode. In step 320, it is detected whether the reserved recording apparatus is turned on. Since the reserved recording apparatus operates in a power-on state (Power On state), the process proceeds to step 330 only when the power is turned on.

In step 330, the user determines whether the key data input through the input unit 10 is set for the reservation mode by a remote transmitter (eg, a remote controller) or a key matrix attached to the main body of the reservation recording apparatus. If the input of the data is not the reserved mode setting data (for example, data indicating the speed control or the volume control of the tape), the function corresponding to the specific key is performed (step 335). Proceed to

When the data input in step 330 is data indicating the reservation mode setting, the text data for displaying the reservation screen is displayed on the display 80 by controlling the OSD unit. The type of data displayed at this time is as shown in FIG. At the top of the display 80, a character (# TIMER reservation #) indicating a reservation mode is displayed and the current time and date are displayed.

When the reservation input screen is displayed in this manner, the cursor is gummed at a position for inputting a date in order to receive data input, and when data is input, it is determined whether the data is data for a reservation date. If the input data is an input of a key not related to a date or the time is delayed without input for a predetermined time, the process proceeds to step 360 to start counting and determines whether the count reaches a predetermined number (predetermined time) (S370). Step (ie, repeating steps 360, 370, and 350). If the count does not reach a certain number, the process returns to step 350. If the count reaches a certain number, the count is reset and the reservation screen data is turned off (step 380). . Steps 360 to 380 of the above steps are routines that perform the same process in the data input section, which will be described later.

If the reservation date is input in operation 350, the input date data is displayed on the screen (operation 390). When the date data is displayed on the screen, the cursor is positioned at the position for inputting the next data, that is, the channel input position, to determine whether the channel data is input (step 400). If there is no input of the reserved channel or input of wrong data, block A (step 410) is performed.

If there is an input of reserved channel data in operation 400, the corresponding data is displayed on the display 80. When the channel data is displayed on the screen, the cursor is located at a position for inputting the next data, that is, at a start time data input position of the reservation program (step 430). If there is no input of the start time data or input of incorrect data, block A (step 440) is performed.

If the start time data is input in step 430, the input start time data is displayed on the screen (step 450). When the start time data is displayed on the screen, the cursor is located at a position for inputting the next data, that is, at the end time data of the reservation program (step 460). If there is no input of the end time data or input of incorrect data, block A (step 470) is performed.

If the end time data is input in step 460, the input end time data is displayed on the screen (step 480). As described above, the reservation data input by the user made in steps 400 to 480 is stored (step 490).

After the input data by the user is stored, the difference between the start time and the end time of the input reservation program is calculated to calculate the time to be recorded, and the microcomputer 30 sends a control signal to the recording unit 60 in the recording unit 60. The recording speed of the tape is automatically set by calculating the recordable time by measuring the amount of tape installed (step 500).

This automatic recording speed setting function is commonly called JUST REC function. If the recording time is longer than the remaining capacity of the recordable tape, the automatic recording speed setting function automatically changes the recording speed of the tape from SP to LP or SLP to perform scheduled recording. It refers to a function that changes the recording speed after detecting the remaining amount of recordable tape and comparing the time to record.

After the automatic recording setup step is performed, the guide data is output on the display 80 (step 510). When an example of the guide data is shown in FIG. 6, a guide text such as pressing the [reservation] button and the like is output on the display 80 using the OSD unit 70.

After performing step 510, it is determined whether there is an input of data indicating a reservation standby mode (step 520). If the data input is not the data indicating the reservation standby mode (for example, pressing the reservation button again to reserve another program or pressing the play key to play a program, etc.), the process returns to step 330. do. However, if data indicating the reservation standby mode is input, the operation proceeds to the reservation standby mode (standby state). At this time, depending on the configuration of the reservation recording device, the input data type can be switched to standby mode by pressing the power button to turn off the power or pressing the timer button when the power cord is plugged in.

As described above, the present invention can easily perform scheduled recording only by inputting basic data on one screen and automatically set the recording speed so that the recording speed of the tape can be maintained even if the amount of tape is insufficient. It is effective to reserve the entire program by adjusting.

As described above, the present invention is divided into several steps of the prior art, so that each of the input data is inputted by one screen, and the data input by the user can be set automatically, thereby simplifying the setting of the reservation data. .
