The present invention relates to a repeating device for repeating a specific section of a VCR. In particular, when a user wants to see only a section that has been set with several sections, only the set section is played while skipping an unnecessary section so that the necessary scene can be viewed in a short time. The present invention relates to a method and an apparatus for repeating playback of a specific section of a VCR.

In the conventional VCR reproducing apparatus, as shown in FIG. 1, the output of the keyboard B is applied to the ciscon micom A, and the ciscon micom A controls the up / down counter D in which a reel pulse is input. The output of the up / down counter D is simultaneously applied to the ciscon micom A and the register E, and the register E is controlled by the load signal LOAD of the ciscon micom A. The output is applied to the ciscon micom (A), and the output of the ciscon micom (A) is connected to the VCR traveling system (C).

The operation state of the configuration apparatus will be described in detail with reference to the flowchart of FIG. 2 as follows.

In the VCR playback mode, the scissor micom (A) outputs a reset signal to reset the up / down counter (D), and then the scissor micom (A) is connected to the up (UP) terminal. ', And' LOW 'to the DOWN terminal to allow the up / down counter (D) to count up. Then, when the siscon micom (A) receives the start point of the repeated play of a specific section through the keyboard (B), the siscon micom (A) outputs an enable signal to enable the up / down counter (D). To count the reel pulses. Next, the siscon micom (A) waits to input the stop point for repeating a specific section from the keyboard (B), and when it receives the stop point, it outputs a load signal and outputs an up / down counter (D). The data value counted through is stored in the register (E), and then the Syscon micom (A) outputs a 'low' signal to the up terminal and a 'high' signal to the down terminal so that the up / down counter (D) It operates as a down counter and allows the VCR traveling system C to perform the rewind mode.

During rewind mode, the Syscon Micom (A) checks whether the data counted through the up / down counter (D) becomes zero and returns to zero (when it comes to the start point of a specific section repeat play). Perform

If the data value counted through the up / down counter (D) and the data value stored in the register (E) are the same during the play mode, it is checked whether the repeat process has been executed n times. Returning to the process of repeating the process after that, if the repeating process is completed n times, the repeat mode (REPEAT MODE) is released and the normal play mode is continued.

However, in the conventional VCR playback apparatus as described above, only one section of the VCR tape section can be set, and when the repeat section is to be set again after executing the set section, there is a need to set the section again. .

In view of the above-described problems, the present invention designates a plurality of repetition sections of all sections of a VCR tape and reproduces only the designated multiple repetition sections, which will be described in detail with reference to the accompanying drawings. .

First, referring to the configuration of the VCR playback apparatus according to the present invention in FIG. 3, the system signal for controlling the overall system of the VCR is an output signal of the keyboard B (repeat play, repeat play set, start, stop signal). Up / down signal is applied to the VCR traveling system (C), and up / down signal and reset signal (Reset) of the sheath microcomputer (A) is applied to the up / down signal. It is applied to the counter D, the output OUT of the up / down counter D is applied to the input terminal X of the comparator K, and at the same time, the write signal WRITE from the ciscon micom A is applied. Being applied to the AND gate 1, the output of the AND gate 1 is stored in the memory G, and the read signal from the ciscon micom A is applied to the output of the memory G. Being applied to the AND gate 2 being applied, the output of the AND gate 2 is applied to the input terminal Y of the comparator K, and the output of the comparator K is It is applied to the cone micom (A), the ciscon micom (A) is connected to the non-setting display (J), the reset signal of the ciscon micom (A) is the maximum area number register (H), the test register (I) And a maximum area number register (H) and a test register (I) are connected to the ciscon micom (A), and the ciscon micom (A) is connected to the area address register (F). The output of the area address register F is connected to the memory G.

That is, the present invention is connected to the keyboard (B) and the VCR traveling system (C) for controlling the overall system of the VCR, the up / down counting the reel pulse generated on the side to be wound during VCR tape driving The down counter (D) is controlled by the ciscon micom (A) and the counted output is applied to the comparator (K) and connected to the memory (G) for storing binary data through the AND gate (1). Stores the counting counting data of the start and stop points of the sections to be used in the repeat play mode. When the output address of the area address register F designating the address of the memory G is applied to the memory G and the address is designated, data is output in accordance with the read / write signal applied from the scissor microcomputer A. It can be written or lead. In addition, a maximum area number register (H) indicating how many setting sections are currently present, a test register (F), a maximum area number register (H), and a test register (H) for storing temporary data in a multi-specific period repeat playback mode ( I) is controlled by the ciscon micom A, and the comparator K receives the output of the up / down counter D and the signal from the memory G, compares the output, and compares the output with the ciscon micom (A). A non-setting display J, which is applied when A) is applied and is operated when the section setting is not made, is connected to the scissor micom A.

The operation of the configuration apparatus will be described in detail with reference to the flowcharts of FIGS. 4 and 5 as follows. In the VCR playback mode, when a command to perform the multi-part repeat playback mode is input from the keyboard B to the scissor micom A that controls the general VCR system, the scissor micom A indicates an up signal. Outputs high and outputs the down signal 'low' to set up / down counter (D) in up count mode. Then, check the data in the maximum area number register (H) and if the data is zero, then the interval setting is If it is determined that nothing has been done, you inform the user to make section settings by turning on the setting display (J).

If the data of the maximum area number register (H) is not zero, the scissor microcomputer (A) initializes the test register (I) to zero and the area address register (F) to "1", and then in the test register (I). The data is increased by " 1 " and the read control signal is output so that the data at the beginning of the region 1 of the memory G is output through the AND gate 2 and applied to the input terminal Y of the comparator K. The comparator (K) compares the current reel pulse counting value (X input data) applied from the up / down counter (D) with the input data applied to the input terminal (Y) and compares the result with the ciscon micom (A). Then, the scissor microcomputer A increments the data in the area address register F by one.

Then, the region 1 stop data of the memory G is output through the AND gate 2 and applied to the input terminal Y of the comparator K, where the comparator K is applied to the input terminal Y. The data of "stop" and the magnitude of the current reel pulse counting value applied to the input terminal X are compared and the comparison result is applied to the ciscon micom A.

Then, the Syscon Micom (A) determines whether the inequality of "area 1 start <current counting value <area 1 stop" holds, and if the inequality is established, the user sets the test register after performing the regeneration mode. Return to the process of initializing to zero and repeat the subsequent steps, and if the inequality of "area1 start <current counting value <area1 stop" is not satisfied, the test register (I) and the maximum area number register (H) It is judged whether or not the various sections that have been set by comparing the data of the data are not checked (test register (I) data ≠ maximum area number register (H) data). The contents of the area address register (F) are increased by 1 (area 2 start). Point designation), the contents of the test register I are increased by one, and it is determined whether the present counting value is within the start point and the stop point of the area 2. This operation is carried out as much as the data amount of the maximum area number register (H). If the current counting value is within several setting ranges, the playback mode is executed. The section not set by performing is skipped.

If the playback and the FF mode are executed to the end of the tape and the end of the tape is reached, the Syscon micom (A) sets the up / down counter to the down mode and then controls the VCR driving system (C) to rewind. Try running the mode.

As described above, after the lawind mode is continuously performed to the initial part of the tape, in the initial part of the tape, the ciscon micom (A) controls the VCR driving system (C) to perform a regeneration mode. One operation loop is repeated from the keyboard B until an input for canceling the multi-part repeat play mode is applied. If the multiple specific section play mode key has not been input to the Sicon Micom (A), check whether the multiple play mode setting mode key has been input from the keyboard (B), and the multiple play mode setting mode key is input. If not, the VCR normal mode is executed, and if the section repeat play setting mode key is input, the section setting mode routine is executed. At this time, the section setting mode routine is shown in FIG.

That is, first, the up / down counter (D) is set to the up mode, and if there is no area start key input, it is determined whether it is a multi-specific section repeat play setting mode, and if there is an area start key input, the contents of the area address register (F) are changed. After increasing, the write signal is output and the area start point is stored in the memory G.

Then, if there is no area stop key input, it is determined whether it is a multi-section repeat play setting mode. If there is an area stop key input, the contents of the area address register F are increased by one, and a write signal is output to store the area stop point in memory ( Save to G). Then, after increasing the contents of the maximum area number register (H) by one, it is checked whether it is a multi-part repeat play setting mode, and in the multi-part repeat play setting mode, it returns to the process of checking whether there is an area start key input. Subsequently, the process is repeated, and the process returns to the process of determining whether or not the multiple specific section repeat playback mode is selected (FIG. 4).

As described above, the present invention can designate a plurality of repeat playback sections of the entire tape section of the VCR, and if the repeat playback mode is performed, the section that is not set is skipped, so that the desired scene can be viewed in a short time. Since the previously set section is maintained as long as the section setting is not reset, there is an effect that can provide convenience to the user.
