VCRs and repeating methods for repeating a specific part of a tape

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a video cassette recorder (VCR) having a function of displaying the remaining amount of tape, and more particularly, a VCR capable of detecting a remaining amount of tape and repeatedly playing back only a specific portion of the tape divided by the remaining amount. It is about a method.

In general, a VCR receives a signal from a broadcast signal transmitted from a broadcasting station or a device such as a television and records it in a video cassette having a magnetic tape, or reads information recorded in a predetermined video cassette to a display device such as a television. It is a device for transmitting. Recently, a multifunctional VCR with a clock function and a remaining tape display function has been widely used. Among these, a remaining tape display function detects the amount of the video tape that is being played or recorded by the VCR, or the amount of recorded video. Indicates the function to display the function as a counter. This function allows the user to find out where on the tape the information recorded on the videotape is located. Such remaining amount display is implemented by a mechanical counter or an electronic counter. Recently, an electronic counter is frequently used.

Referring to the bar shown in Figure 1 will be described with the electronic counter remaining capacity display function as follows. 1 is a schematic diagram showing a conventional example of displaying the remaining time of a tape by using an electronic counter. A pulse signal generated each time the reel is rotated by a detector provided on the supply side reel and the reel side reel at the time of recording and reproducing the tape is provided to the system controller. The system control unit distinguishes between the release pulse signal and the tape speed information of the standard mode (SP) or the long time mode (SLP), and whether the tape is thin (for example, 3 hours) or ordinary tape (for example, 2 hours). Calculate the remaining tape time with and display it on the electronic counter. The reel rotation speed rotates slowly when the amount of tape wound on the reel is large and rotates rapidly when the amount of tape is low. Therefore, the system controller can calculate the amount of tape wound on the reel from the reel pulse signal and calculate the remaining time. It becomes possible. The remaining time calculated in this way is transmitted to and displayed on the electronic counter as shown. Therefore, the user can grasp the position of the tape where the video recording or the like currently being reproduced is located.

In the conventional VCR having the remaining tape display function, it is possible to determine which information is recorded according to the relative position of the tape. However, when the user wants to play the information repeatedly, the user manually rewinds and plays the data. The function had to be used, and it was also inconvenient to find the location.

Therefore, the present invention has been invented to solve the above problems, VCR and tape specific portion which can detect the remaining amount of tape and repeatedly play only this specific portion by designating a specific portion of the tape divided by the remaining amount. Its purpose is to provide a repetitive playback method.

In one embodiment of the VCR, a flow chart illustrating a process of repeatedly playing a specific portion of a tape is shown.

As shown in FIG. 2 for convenience of explanation, other components are simply omitted, the video cassette recorder (VCR) having the remaining tape display function according to the present invention can select various functions and input predetermined data. An operation unit 10 having a key, a display unit 30 for displaying the remaining amount of tape, a memory unit 22 for storing predetermined data related to repetitive playback, and a reproducing mechanism 50 for reproducing information recorded on the tape. And a system controller 20 which detects and displays the remaining amount of tape and controls the playback mechanism 50 in accordance with a signal input from the operation unit 10.

The operation unit 10 may be, for example, a wireless input device such as a remote controller, or may be installed on the front panel of the VCR. The operation unit 10 includes a function key for selecting various functions of the VCR, as well as a ten key for inputting numerals or letters. In addition, the memory unit 22 stores data relating to repetitive reproduction, in particular, related to the present invention. For example, data representing a repetitive reproduction start point R1, data representing a repetitive reproduction end point R2, and a repetition reproduction frequency RN ), And the like. In addition, data indicating the remaining amount of tape provided to the counter unit 32 provided in the display unit 30 to display the remaining amount of tape is also stored. As shown in the drawing, the display unit 30 displays various information such as a function for displaying the current time in addition to the counter unit 32 in which the remaining amount of tape is displayed, or an indication indicating whether the tape is currently mounted. can do.

The system controller 20 calculates the remaining amount of the tape based on the reel rotation signal and other tape related information provided from the winding side reel 42 and the supply side reel 44 of the tape, and displays the calculated remaining data. To be displayed. The remaining amount calculation method of such a tape may use a conventional method known in the art. In addition, the system controller 20 stores data related to repetitive reproduction input from the operation unit 10 in the memory unit 22. Once the repetitive reproduction function is started, the system control unit 20 stores the memory unit ( The playback mechanism of the tape is controlled based on the data stored in 22).

The control algorithm related to this repetitive reproduction is incorporated in the system control unit 20 as a logic circuit. Referring to the flow chart shown in Figure 3 will be described in detail the control algorithm related to the repeated playback embedded in the system control unit 20 as follows.

First, the point R1 at which repeat playback starts, the point R2 at which it ends, and the number of times RN to repeat are set (step T1). The setting data may be a combination of various function keys and ten keys provided in the operation unit 10, and the system control unit 20 stores the data input from the operation unit 10 in the memory unit 22. The system control unit 20 also has a function of detecting the remaining amount of tape and sending the remaining amount of data to the display unit 30 for display, which can be easily understood by those skilled in the art. That is a known technique.

This remaining amount data should be continuously compared with the R1, R2, and RN when the system control unit 20 controls the repeat playback function. Therefore, the reference when the system control unit 20 performs the operation of finding the R1 point, for example, becomes the remaining amount data. This remaining data usually means the relative position of the tape. That is, the data relating to the position is recorded in advance on the magnetic tape, and the data is not calculated by detecting the data. Instead, the system controller 20 calculates and displays the data by referring to the rotation speed of the tape and the tape thickness. The remaining data is sent to the counter section 32 of the display section 30, and the system control section 20 detects the data displayed on the counter section 32, and the remaining data of the tape serving as a reference for control during repeated playback. Will be made.

Once the data related to the repeat playback is set, the user starts the repeat playback function by using the function key of the operation unit 10 (step T2). When the signal for starting playback is received from the operation unit 10, the system control unit 20 compares the remaining amount data displayed on the counter unit 32 with the repeated playback start point R1 and starts playback if it is the same. Control the winding and rewinding mechanism (not shown) so that the data displayed on the counter 32 has an R1 value (step T3).

In this way, when R1 is displayed on the counter 32, the system controller 20 starts driving the regeneration mechanism 50 (step T4), and the data displayed on the counter 32 is continuously changed and R2. Compare the values. If the remaining amount data displayed on the counter 32 and the R2 value are the same, the system controller 20 stops playback, decreases the RN value stored in the memory 22 by 1 (step T5). Check whether the value is less than 0 (step T6). If the RN value is positive, the playback operation is performed again by repeating steps T3 to T6 again. If the RN value is 0, the playback is repeated as many times as the number of repeats is set, so the repeat playback ends.

According to the configuration of the VCR having the specific part repeat playback function of the tape and the specific part repeat playback method of the tape according to the embodiment of the present invention described above, the user can add only the specific part of the desired tape in addition to the conventional tape remaining capacity display function. Since it can be played back as many times as desired, a more convenient VCR can be provided.

Although a VCR having a specific portion repeat play function of the tape and a specific portion repeat play method of the tape according to an embodiment of the present invention have been described above in detail with reference to the accompanying drawings, the present invention is not limited thereto, Modifications or improvements are possible within the scope of ordinary knowledge.
