The present invention relates to a method for distributing input work time to be inputted to a plurality of operators when creating a broadcast subtitle or a speed recording, and more particularly, to play back and record recorded video and audio in real time. The present invention relates to a method of distributing input work of a shorthand input system that can be conveniently inputted to suit an individual's ability by distributing a certain amount to workers by breaking a predetermined time or a silent section.

Subtitle display broadcasting refers to displaying Korean or English subtitles on a video screen such as a movie, TV, or internet broadcasting for the hearing impaired or language education, which inserts character information corresponding to an audio signal at a specific position of the video signal. The receiver receives the received information, separates and decodes the corresponding character information through a TV or a computer with a built-in character broadcast decoder, or through a subtitle decoder device separately installed, synthesizes the image with a video signal, and then sends the text to the video signal. By superimposing and displaying the signals.

For such caption broadcasting, a shorthand character input system for caption broadcasting is required, and such a device is disclosed in Korean Patent Registration No. 10-0325501.

In the shorthand character input system for caption broadcasting, since a program broadcasted in real time proceeds for a long time at a high speed, it is common for a plurality of character inputters to alternately input them by character input means.

In addition, the shorthand input system which distributes input work by a predetermined amount to a plurality of shorthand journalists is used not only for caption broadcasting as described above, but also for recording real-time input, meeting minutes, or recording by recorded video. .

Korean Patent Publication No. 10-0187689 discloses a voice signal distribution device for shorthand. When the voice signal is input, the device can perform a computer shorthand while listening to a plurality of shorthandists by alternately rotating a predetermined amount. It is a voice signal distribution device for shorthand for informing each registrar sequentially so that the shift signal.

However, such a conventional dispensing device must perform the input operation only by the voice signal given to the inputter without visual information about the surrounding situation, and even a skilled inputter can divide and distribute the continuously inputted voice signal. There was a problem that it is very likely to miss a character to enter or typos.

In addition, a plurality of inputs should work together while listening to a voice signal, and by observing a signal such as a sound or a graph, the inputs can recognize their input order so that each input user can clearly see the start and end of his work. There was a problem that was difficult to grasp.

On the other hand, to solve the problem of the former, Korean Patent Publication No. 2001-0037166 discloses a voice transmission control device and a control method for computer shorthand, which continuously records the external voice generated in the field memory The present invention relates to a control device and a method for controlling the stored voice and controlling the stored voice at a desired speed and interval to be delivered to the reporter.

However, even in the above case, the input operation should be performed only by the voice signal given to the inputter without visual information about the surrounding situation, and the input operation should be performed while the multiple inputters listen to the voice signal together, and the signal such as the sound or the graph may be used. There was still a problem that it was difficult for each inputter to clearly understand the start and end of his work by allowing the inputters to recognize their input order by watching.

The present applicant provides not only the voice but also the visual image information to the inputter, and allows the inputter to check the input while playing the voice and the image on the computer screen by adjusting the playback speed by recording and recording the image and the voice. It has been registered with the Korean Patent Registration No. 10-0578551 for a shorthand composite device and a remote shorthand method using the same.

In addition, the present applicant, the distribution system for input time distribution and caption data sharing, input system for inputting subtitles while watching recorded media files, real-time correction of the input subtitles and correction system for transmitting the completed subtitles The Korean Patent Application No. 2005-0063842 has been filed for a real-time broadcasting subtitle input and transmission system including a transmission system for transmitting a inspected subtitle to a broadcasting station through wired or wireless communication.

The above-mentioned registration or application by the present applicant is a system capable of inputting subtitles while recording the video and audio of TV, etc. in real time and changing the playing time according to each inputter's ability through the recorded screen. The system can improve the accuracy.

However, even in the above system, when the input time is distributed to a plurality of inputters in a predetermined order, the inputter watches the screen on the input computer monitor and notifies each inputter of the start and end by sound. In this regard, each inputter is the same as the conventional method in that it recognizes the start and end points while watching the same image and sound in succession although they are separate screens assigned to each user.

Therefore, there may still be a problem in which inputters miss starting or ending timings or typos are generated due to problems such as deterioration in concentration due to viewing successive screens.

Therefore, the technical problem of the present invention for solving the above problems is, in the input work distribution method of the shorthand input system, the real-time video recording at the same time or at the same area or remote while playing the recorded video recording By dividing and distributing the video content by a set amount to the input users who are located, it is possible to improve the accuracy of subtitle input by increasing the concentration of the inputter.In addition, by adding a repeating section at the time of distribution, the uncertainty of the disconnection part due to the segmentation or media data can be improved. It is to provide a method for distributing input work of a shorthand input system that can prevent the difficulty of semantic grasp due to the partitioning of the.

The present invention to solve the above technical problem,

In the shorthand input system in which a video is stored and displayed in real time, or a recorded video is displayed and inputted by a user while watching a media file, the subtitles are input and modified using wired / wireless communication, a plurality of inputs are divided by the input amount. In the input work distribution method of the shorthand input system for inputting characters alternately,

A first step of setting an inputter and setting an input order and an input time of each inputter for the set plurality of inputters;

A second step of sequentially distributing video and audio corresponding to each set input time according to the input order to only the corresponding inputter among a plurality of inputters; And

Determining whether playback is to end or not, repeating the second step if continuing and terminating distribution if terminated; It provides a method for distributing input work of the shorthand input system comprising a.

The division of the video and audio data in the first step may be set by dividing at a predetermined time or by searching for a silent section and setting the silent section as a unit.

In the second step, when distributing to the first inputter and then distributing to the next inputter, the divided sections may be distributed so that the divided sections do not overlap, or the divided sections include a repeating section overlapping by a predetermined amount.

In addition, the distribution in the second step may transmit the video and audio data not only to the case of transmitting to a plurality of inputters gathered in the same area, but also to a plurality of inputters located at remote locations.

Hereinafter, the input work distribution method of the shorthand input system according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

4 is a view for explaining the concept of the input job distribution method of the shorthand input system according to an embodiment of the present invention.

Referring to FIG. 1, the shorthand input system includes a distribution unit 10 for distributing an input order and an input time to a plurality of inputters and sharing caption data, while the inputter watches a recorded media file. A plurality of input units 20 for inputting subtitles into the input device, a correction unit 30 for correcting the input subtitles in real time and transmitting the corrected subtitles, and a transmitter for transmitting the inspected subtitles through wired or wireless communication. And 40.

The distribution unit 10 receives and stores the media data and simultaneously reproduces the input media data in real time, distributes the video and audio for each set input time by the set input time, and inputs and corrects them. Subtitles are relayed to the connected input unit 20 and correction unit 30 so that the subtitle data is shared.

The input unit 20 inputs and stores captions to an input device such as a keyboard based on the video and audio data divided from the distribution unit, and transmits the input captions to the distribution unit 10 and the correction unit 30. Display in the input window.

The correction unit 30 displays the caption data transmitted from the input unit 20 in the correction window so that the modifier can edit and store the data.

The transmitting unit 40 converts the subtitle data transmitted from the correction unit 30 according to the transmission format and transmits it to the outside using an internet network or a wireless communication network.

In the shorthand input system configured as described above, the input job distribution method according to the embodiment of the present invention made by the distribution unit 10, as the caption broadcasting is started, a plurality of input characters are divided by the input amount of the subtitle characters. As a method to alternately input, it is configured as shown in Figure 2, which will be described in detail as follows.

First, as a first step S1, input order is given to all input users connected to the shorthand input system, and the video and audio data are divided by the input time set for each input user. The input time is a value that can be arbitrarily set by the distributor or each inputter, and can be assigned an appropriate time for each inputter's ability.

On the other hand, the division of the video and audio data in the first step (S1) can be set by dividing by a predetermined time or by searching for a silent section, and can be divided by setting the silent section as a unit.

In other words, in consideration of the capability of each inputter and the desired input time, a method of dividing A input by 3 seconds, B input by 5 seconds, and C input by 10 seconds can be used. It is possible to use a method of searching for silent sections from the received media data by making each silent section into one unit, and then dividing by a predetermined amount by the unit.

Next, as the second step S2, the divided video and audio data are sequentially transmitted in accordance with the above input sequence assigned to each inputter. Therefore, when one inputter receives the divided video and audio data to be input by the distributor 10, it is not transmitted to the other inputter, and when the other inputter receives the data to be input by the other inputter, It is not sent to other inputters.

In this way, each inputter can not watch the video and audio data from the input unit during the time that he or she does not input, but can only watch when the user inputs, thereby greatly increasing the concentration of the inputter.

On the other hand, as can be seen in Figure 3, when the second step (S2) is distributed to the first inputter after distributing to the next inputter, the divided sections are distributed so as not to overlap, or the divided section is a certain amount It can be distributed to include overlapping intervals. This will be described in detail as follows.

First, a case in which the divided sections are distributed so as not to overlap with reference to FIG. 3 (a) will be described.

It is assumed that the input time of each inputter is set to 3 seconds for input A, 5 seconds for input B, and 10 seconds for input C.

In this case, the video and audio data for 18 seconds are divided into three sections of 3, 5, and 10 seconds, and the divided three video and audio data are sequentially distributed to the A, B, and C inputters.

That is, after providing the first 3 seconds of data for 3 seconds to the inputter A, the inputter A stops until the next turn, and then provides the second 5 seconds of data for 5 seconds to the inputter B. The inputter stops until the next turn, and next, after providing the third input 10 seconds of data to the inputter C for 10 seconds, the inputter C repeats the cycle until it stops until the next turn.

Therefore, after inputting A for 3 seconds, input A stops until the next turn, input B input for 5 seconds and stops until the next turn, input C input after 10 seconds, and until the next turn comes. In order to stop.

In addition, referring to FIG. 3 (b), a case in which the divided sections are overlapped by a predetermined amount and distributed to include a repeated section is as follows.

As in the above, it is assumed that the input time of each inputter is set to 3 seconds for A input, 5 seconds for B input, and 10 seconds for C input, and the repetition section is set to 2 seconds. However, this is only one example, and the stop time and repetition time may be arbitrarily set by each inputter.

In this case as well, the video and audio data for 18 seconds are divided into three sections of 3 seconds, 5 seconds, and 10 seconds, and the three divided video and audio data are sequentially sent to the A, B, and C inputters. Although distributed, the repetition period is included in each of the above data.

That is, after providing the first 3 seconds of data for 3 seconds to input A, the input A stops until the next turn, and then repeats the second 2 seconds of the first 3 seconds of data, which is input to input B. After the 7 second data is provided as the 7 second data in addition to the front of the second data 5 seconds as the interval, the input B is stopped until the next turn, and the second data is input to the input C for 5 seconds. After the second 2 seconds of the data is added as the repetition section, the second input is added to the front of the 10 second data and provided as 12 second data for 12 seconds, and the C inputter repeats stopping until the next turn comes.

Therefore, after inputting A for 3 seconds, A input stops until the next turn, input B input for 7 seconds including 2 seconds of repetition section, and stops until the next turn. After entering 12 seconds including, it will proceed in the order of stopping until the next turn comes.

FIG. 4 is a diagram illustrating the above-described concept so that the concept can be easily understood. As illustrated in FIG. 4, the A inputter sets the repetition section 0.5 seconds and the input time 3 seconds, and B is different from the above example. The example illustrates a case where an inputter sets a repeating section 1 second and an input time 5 seconds, and a C inputter sets a repeating section 1 second and an input time 10 seconds.

In case of setting as above, input A inputs 3 seconds of input while watching 3.5 seconds of 0.5 seconds of repetition section and 3 seconds of input time, and B inputs 1 second of repetition section and 5 seconds of input time. The user inputs 5 seconds of input work while watching for 6 seconds in total, and C inputter performs 11 seconds of input work while watching for 11 seconds, which includes 1 second of repetition section and 10 seconds of input time.

In other words, if the input point of the input data input by the input user A is the reference point, the input user A inputs 3 seconds while listening for 3.5 seconds from the point of 0.5 second retreat from the reference point, and the input user B inputs the work end point of the input user A. Input 5 seconds while listening for 6 seconds from 2 seconds to 8 seconds from the reference point corresponding to 1 second retreat from 3 seconds The 10-second volume is input while listening for 11 seconds from the 7-second point to the 18-second point at the reference point corresponding to the retreat point.

In this configuration, the next inputter can watch the rear part of the previous inputter again, thereby preventing the difficulty of understanding the meaning of the disconnection part due to the division or the division.

In addition, the distribution in the second step (S2) is not only a case where a plurality of inputs are gathered in the same area, it is also possible to distribute and transmit the video and audio data using a network in a state located in a remote place with each other.

Next, as a third step (S3), it is determined whether the reproduction is finished by the distribution unit 10. At this time, if the reproduction is continued, the second step (S2) is repeated, and when the reproduction is terminated. Terminate distribution of input work.

According to the input work distribution method of the shorthand input system of the present invention as described above, the set amount is set to a plurality of inputs located in the same area or remote while playing the real time video at the same time or playing the recorded video. By dividing and distributing the images as much as possible, it is possible to improve the accuracy of input of subtitles by increasing the concentration of inputters.In addition, it is difficult to grasp meanings due to the uncertainty of the disconnection part due to division or the division of media data by adding a repeating section during distribution. There is an effect that can prevent.
