The present invention relates to a method of reserved recording of a V.C. egg, particularly to detect an unrecorded section of a cassette tape mounted on a deck portion of a V.C. egg and to execute a reservation recording in the largest section of the unrecorded section. It is about reservation recording method of V.C.R.

In general, V.C.E. in syntactic sugar has a reservation recording function. In this reservation recording, a program that is broadcast after the current time is set in advance so that when the program is broadcast, V.C.R. Therefore, reservation recording is mainly used when a television cannot be watched at a time when a desired specific program is broadcasted.

In recent years, users tend to use such reservation recording for various reasons such as the variety of programs and dressing.

1 is a schematic block diagram of a conventional V.C. reservation recording apparatus.

1 shows a reservation recording apparatus according to a key input unit 10 generating a corresponding input signal when a user presses a specific key (not shown) and an input signal provided from the key input unit 10. A control unit 20 having a timer 22, a microcomputer 24, a memory 26 for generating a control signal and predetermined data, and a predetermined control unit provided with the control signal in accordance with a control signal provided from the control unit 20. OSD processing unit 30 for outputting the data on-screen display (OSD), the display unit 40 for displaying the output signal provided from the OSD processing unit 30 and the power is 'on' when the scheduled recording time comes to the antenna ( A tuner unit 60, a signal processor 70, and a deck unit 80 for pre-recording the signal of the reserved channel set among the broadcast signals transmitted through 50) are included.

FIG. 2 is a partial detailed view of the key input unit 10 shown in FIG.

The key input unit 10 may be key metrics mounted on the V.C.R., and may be a remote controller for remotely controlling the V.C.R.

As shown in FIG. 2, the key input unit 10 includes a numeric key 11, a power key 12, a rewind key 14, a play key 16, and a fast forward key ( 15), a stop key 13, a recording key 17, a reservation key 18, and a setting key 19.

When the user presses the reservation key 18 of the key input section 10 for reserving a specific program, the input signal is provided to the microcomputer 24. At this time, the microcomputer 24 reads the reserved recording data stored in the memory 26 and outputs the data to the OSD processing unit 30, and the OSD processing unit 30 processes the data to the display unit 40 by OSD processing. The display 40 displays this, as shown in FIG.

That is, when the reservation key 18 signal is input, as shown in FIG. 3, V.C.R. becomes a reservation ready state.

As shown in FIG. 3, data necessary for reserved recording of a specific program is composed of a channel broadcasted to a program to be reserved, a date, a start time, and a type time. In addition, when performing weekly recording or continuous recording, the data to be reserved may be slightly changed, but the data shown in FIG. 3 may be regarded as an essential component.

As such, when the image shown in FIG. 3 is displayed on the display unit 40, the user inputs the data in sequence using the numeric keys 11 and the like from this time, and the data, that is, the channel, date, and start. When input of time and end time is completed, press setting key (19). After pressing the setting key 19, the image screen as shown in FIG. 3 displayed on the display unit 40 disappears, and the set data are stored in the memory 26. In other words, the reserved recording of the desired specific program is completed. In addition, several programs can be reserved through this process.

Thereafter, the microcomputer 24 compares the date and time of programs reserved in the memory 26 with the current time of the timer 24, and if the current date and time of the timer 24 matches the reserved date and time, V. C. is to perform recording to the reserved channel under the control of the microcomputer 24, which will be described in detail as follows.

When the preset recording time is set, the microcomputer 24 generates a control signal to a power supply unit (not shown) to supply power to the entire V.C.

Thereafter, the tuner unit 60 tunes the broadcast signal of the reserved channel among the broadcast signals received from the antenna 50 under the control of the microcomputer 24 to provide it to the signal processor 70, and the signal processor 70. After the tuned broadcast signal is subjected to signal processing such as demodulation, video / audio signal separation, and the like, a signal of a type that can be properly recorded on a cassette tape is provided to the deck unit 80.

The deck unit 80 records the signal provided from the signal processing unit 70 on the cassette tape under the control of the microcomputer 24.

On the other hand, the cassette tape must be attached to the deck unit 80 in advance before performing such a reservation recording, there are some items that require attention in mounting the cassette tape, two of which are as follows.

1) Is there a recording tab on the cassette tape to be loaded?

2) Is there a program that needs to be stored on the cassette tape to be loaded?

First of all, in the first precaution, if the recording tape is removed from the cassette tape, the scheduled recording cannot be executed.In the second precaution, if the pre-recording is performed while other programs required by the user are recorded, the previously recorded program is It may be erased and troubled by the user. In the first case, the user can easily know before mounting the cassette tape, but in the second case, the user cannot easily find out without paying attention.

For this reason, a method of detecting an unrecorded section of the loaded cassette tape and performing weak recording in the section has been devised. However, such a conventional recording method performs reservation recording in any of the unrecorded sections, so if the unrecorded section is shorter than the section to be reserved, it may not be able to completely watch the desired part and thus may not be able to watch the desired part. There was a problem.

Accordingly, the present invention has been made to solve the above problems, and an object of the present invention is to detect an unrecorded section of a cassette tape mounted on a deck for reservation recording, and to execute a reservation recording in the longest section of the cassette tape. The present invention provides a method of reserved recording of a V.C. egg which prevents erasing of a previously recorded program and also reduces a short recording period so that reservation recording is not fully executed.

According to a preferred embodiment for achieving the above object, the present invention provides a recording method of V. C. R, the method comprising the steps of checking the current time in the state of waiting for recording reservation; Determining whether the current time in the step has reached the reserved recording preliminary operation time, and if the preliminary operation time has been reached, rewinding the cassette tape to a starting point and stopping it; Performing a process of detecting a control signal unrecorded section on the cassette tape while performing fast forwarding of the cassette tape and storing the same to the end of the cassette tape; Comparing the control signal unrecorded section memorized in the above step to determine the largest section, and then driving the cassette tape to the starting point of the largest section to match the recording head of the V.C.R. Wow; After completing the above steps, the method returns to the reserved recording standby state and checks the current time to execute the scheduled recording when the current time reaches the scheduled recording start time.

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

4 is a flowchart of a reservation recording method of V.C.R according to a preferred embodiment of the present invention.

In order to execute the present invention, a program to be reserved is reserved in the V.C.al memory 26, and the V.C.al should be in the standby for recording. That is, standby power is supplied only to the timer 22, the microcomputer 24, and the memory 26, and the other part is in the power-off state. Based on this, the flowchart of FIG. 4 will be described.

First, in step S10, the microcomputer 24 checks the current time of the timer 22 in the state of waiting for reservation recording, and in step S20, it is determined whether the current time of the timer 22 is the reserved recording preliminary operation time. Determine. Here, the reserved recording preliminary operation time is a time obtained by adding a preliminary time to the time required to perform some steps (S30 to S70) of all the steps to be described later after step S20, about 5 to 10 minutes before the scheduled recording start time, Or a variable value. In addition, the reserved recording preliminary operation time is automatically set accordingly when the start time of the program to be reserved is set as a reservation. In step S20, if the current time has not reached the reserved recording preliminary operation time, the process returns to step S10. If the reserved recording preliminary operation time is reached, the process proceeds to step S30.

Then, in step S30, the V.C. egg in the standby state is 'on' and then rewinds the cassette tape mounted on the deck unit 80 for the reservation recording. ) Determines whether the cassette tape has been rewound to the starting point, and proceeds to steps S30 and S40 until the cassette tape has been rewound to the starting point. After that, when the cassette tape is rewound up to the beginning, the V.C. stops and the process proceeds to step S50.

In step S50, while fast forwarding the cassette tape, a section without a control signal, that is, a section without a recorded signal, is detected and stored. In step S60, it is determined whether the cassette tape has reached the end. Detect. In other words, in steps S50 and S60, a section without a control signal is detected and stored while traveling at high speed over the entire cassette tape section.

Next, in step S70, the sections with no control signals detected and stored in steps S50 and S60 are compared to detect the largest section, and then the cassette tape is driven to record the starting point of the largest section. Matches

After that, in step S80, the power of the V.C. egg is turned off again, the reservation recording is switched to the standby state, and then the current time is checked. In step S90, the current time checked in step S80 is compared with the scheduled recording start time. When the current time reaches the scheduled recording start time in step S90, in step S100, V.C. The egg's power is 'on' and scheduled recording is executed.

As described above, the present invention executes the reservation recording in the largest section after detecting the unrecorded section by checking the control signal over the entire section of the cassette tape currently mounted in executing the reservation recording. There is an effect that the erasure can be prevented and the unrecorded section is short, so that the reservation recording cannot be completely performed.

While the invention has been shown and described with reference to certain preferred embodiments, those skilled in the art will recognize that various modifications and changes can occur without departing from the spirit and scope of the invention as set forth in the following claims.
