Description

Integrated control device of image, sound and special effects and control method thererof}

The present invention relates to an integrated control apparatus for video, audio and special effects, and an integrated control method thereof. More specifically, when a control signal is sent from a central computer, a device having a code matching the control signal can be implemented. The present invention relates to a video, audio, special effects control device and a control method thereof.

Timecode is now a standardized way to sync film, video and audio. A more accurate name for this timecode is SMPTE (Society of Motion Picture and Television Engineers) timecode.

Timecode is basically a sequence of numbers and is recorded continuously like tape on audio, video or film. These numbers become the standard for the speed of the medium and the position. Simply type in to control the rotation speed of the tape, determine where you are looking for, or pinpoint the current position of your program.

However, in reality, no attempt has been made to implement various multimedia using such timecode. That is, the reality is that only time code was used as a means for controlling various multimedia, and such use could not be extended to implement various multimedia shows.

1A and 1B are configuration diagrams showing pulse signals of a time code according to the related art. As shown in Figs. 1A and 1B, the time code is a digital signal composed of "0" and "1". If the signal to be modulated is zero, as in FIG. 1A, one transition occurs for one bit. On the other hand, if the signal to be modulated is 1 as shown in Fig. 1B, it causes two transitions in one bit.

If the digital signals to be recorded are all zero as shown in FIG. 1A, only one transition occurs in one bit period, and thus the modulated signal has an even pulse shape. However, when "0" and "1" are mixed in the digital signal to be recorded as shown in FIG. 1B, pulses having different widths are generated.

The 80-bit coded as described above is divided into 4 bit units to provide information. The basic 4 bits are used to represent numbers from 0 to 9, which is called Binary Coded Decimal (BCD).

The timecode reader reads and interprets the code consisting of "0" and "1" into groups of 4 bits to reproduce single digit decimal numbers. Use these eight decimal numbers to create hours: minutes: seconds: frames. A word contains two other pieces of information in addition to these numbers: user information and motivation.

 The use of such timecode makes it easy to compose a video frame and has various advantages in producing and editing a video. However, the reality is that no efforts have been made to handle various multimedia using these timecodes and control them in time order.

The present invention has been made in order to solve the above problems, the video to implement the video, audio and special effects by storing the operating time information and the implementation of the multimedia in the form of a cue sheet in the SMPTE time code, It is a first object of the present invention to provide a voice and special effects integrated control device.

As shown in Table 1, the leftmost column contains the queue serial number. Next, the time code 5 is described. The time code 5 is composed of time: minute: second: frame. The cue sheet constituting the video, audio, and special effects control device according to the present invention is configured to generate various events over time. .

For the control of these events, the machines for each event are connected to the central computer 100. Hereinafter, the configuration of [Table 1] will be briefly described. First, the luminaire 20 must be in an OFF state, and other devices can be referred to as a standby state.

In Cue 1, the translucent screen 200 descends to the stage 400 to project various images. This down motion occurs for 3 seconds. When the translucent screen 200 comes down, the fog 43 is generated around the translucent screen 200 for 30 seconds by a special effect.

After 1 minute and 30 seconds, the stage performer 250 appears to make a prepared comment, and at this time, the luminaire 20 illuminates the central part with a yellow light. After all, the cue sheet may be referred to as a script provided for a performance on a stage 400. However, the time code 5 is recorded in the second column of the contents recorded in such a cue sheet so that the central computer 100 can control the time code 5 according to the time.

The use of the timecode 5 improves the accuracy on a frame-by-frame basis, and allows repeated editing of the image. The time code 5 distinguishes a video frame or an audio signal on the basis of 24 hours. In the case of the video, audio and special effects control apparatus according to the present invention, the control of the special effects is also possible in addition to the video and audio signals.

As shown in Table 1, the time code 5 is divided into eight digits of hours, minutes, seconds, and frames as shown in 05: 15: 18: 23. The time code (5) distinguishes the position of the frame at the time of editing and uses it as any reference. The time code 5 is digitally encoded and occupies a certain portion on a videotape or audiotape, usually using one of the acoustic tracks (LTC) and sometimes using the vertical retrace period of the video signal (VITC). .

Conceptually, the timecode 5 is similar to the edge number of the film and is an arbitrary number assigned to each video frame. Since the time code 5 is an arbitrary number, the important thing is the figure to which the code is given, not the number on the tape. The time code 5 is always read in the same way. If the time code 5 is recorded correctly, if it is synchronized at the beginning of each frame but is not synchronized to the video source but recorded by the time code generator (not shown) itself, the time code 5 is displaced and cannot be used.

This time code 5 contains further information, that is, user information and synchronization information. The time code 5 is divided into 80 bits across the video frame. Four groups of bits produce decimal numbers from 0 to 9. The 32 bits are for user information, but use only 0 through 9 in simple systems and add A through F in more complex systems. For reference, 4 binary digits represent 16 numbers (0 ~ 9, A ~ F).

This encoding method is called hexadecimal. The user bits can indicate the reels used in the program. For example, the reel number 15 taken on September 20 at the first location is 15: 09: 20: 11. Coding equipment is required to record user information in each video frame.

In contrast, the synchronization information is at the end of the frame, which a timecode reader (not shown) uses to determine the advancing direction of the tape. By this principle, the signal through which the time code 5 flows is a one-way signal and the point where the synchronization signal is located should be the last point that the time code 5 reads.

There are two kinds of time code 5. One is the drop frame timecode and the other is the non drop frame timecode. The drop frame time code is one hour of tape travel and the time travel of the time code 5 is exactly the same, and the non-drop time code is 3.6 seconds longer. The difference between these two timecodes (5) is that the National Television Systems Committee (NTSC) color TV signal is 29.97 frames instead of 30 frames per second. However, when the time code (5) was first released, it was 30 frames per second. However, the error of 0.03 frames per second is 3.6 seconds per hour. To compensate for this error, a constant number was excluded from the calculation. This is the drop. Add it all up to 108 frames (3.6 seconds), except for this one hour is exactly right. Therefore, except for the interval of 10 minutes in the configuration time of the time code 5, the interval of a predetermined time is missing. This is called drop frame timecode, which does not affect within a frame. This drop frame timecode is used for programs that require accurate time calculations. For example, it is used in TV programs. This program is edited in seconds and the drop frame timecode is time calculated correctly.

 Non-drop frame timecode is used to edit commercials or production tapes. Advertisements usually don't exceed one minute, so you don't have to worry about excluding two frames, and promotional tapes are edited according to content and mood, regardless of the time in seconds.

The video, audio and special effects control apparatus according to the present invention is configured to operate various multimedia devices over time. Therefore, since time accuracy is required, the NTSC signal using the drop frame timecode is used as the timecode (5) signal.

3 is a block diagram showing a stage 400 in which a device capable of controlling video, audio and special effects according to the present invention is installed. As shown in FIG. 3, the auditorium 300 is arranged in a stepped manner so that the audience can sit. The projector 10 is disposed at the rear of the stage 400. The projector 10 is configured to project various images recorded in the cue sheet.

The viewer can view the video image from the projector 10 through the translucent screen 200. And the laser generating means 150 is located behind the translucent screen 200, it is possible to create a variety of background images. The irradiation state of this laser is as shown in the cue sheet. That is, it is possible to irradiate the laser beams 1 and 6 in the queue 15, to form a space background, and to form various characters on the translucent screen 200 as a background screen. The screening image of the laser generating means 150 and the projector 10 proceeds at regular time intervals as the time code progresses, as shown in [Table 1].

In addition, the luminaire 20 is located behind the translucent screen 200. Such lighting means 20 can be provided with various colors. That is, it may be a yellow lamp, and in some cases, may be a red lamp for finding a specific location. The operation time of the lighting means 20 also commands the various devices according to the time code generator according to the configuration of the cue sheet.

In the case of video, audio and special effects control devices, the use of smog (44), fog (43), wind (42), scent, firecracker (41), soap bubble, sprinkler, gunpowder explosion, etc. It is possible. The device for such a special effect can also be recorded in the cue sheet in advance, and implement various functions for a predetermined time as the time code 5 progresses. Control of the operation signal of the time code 5 is possible remotely and wirelessly.

(Example 2)

In the case of the video, audio and special effects control device, not only this, but also it is possible to implement a three-dimensional stereoscopic image. The image coming out through the projector 10 is not limited to the two-dimensional image. In this case, the 3D stereoscopic image is realized by combining the image generated from the laser generating means 150 and the projector 10.

4A is a photograph showing that an apparatus capable of controlling video, audio and special effects according to a second embodiment of the present invention is realized. As described above, the laser is emitted from the laser generating means 150, and it is possible to implement various images through the laser. Of course, as the background image of the laser, the image from the projector is formed on the translucent screen 200.

As such, when combined with the image from the laser and the projector, the fish realized through the laser forms a rhizome, and the whale out of the image from the projector 10 forms a distant view. However, because it combines several special effects, it is configured to produce a three-dimensional effect. At this time, the actor appeared on stage gives the impression that it is like singing while playing guitar in the water. In addition to these effects, it is also possible to produce an effect such as water drops.

Through such a configuration, a device capable of controlling the video, audio, and special effects according to the present invention can realize an impression such as combining a movie and a theater.

Figure 4b is a picture showing that the device that can control the image, sound and special effects according to the second embodiment of the present invention is realized. As shown in FIG. 4B, the screen containing the image of the universe is reproduced on the translucent screen 200. Then, the laser is emitted from the laser generating means 150 behind the translucent screen 200 to form a certain image. Since the laser image generates a three-dimensional visual effect, it produces a three-dimensional stereoscopic effect.

In addition, when the main character arrives at the flower bed in which the rose blooms, the viewer can feel the fragrance of the rose flower by using one of the special effect generating means 40. Then the audience can empathize with the main character in the stage (400).

Also, when the main character reaches the fountain (not shown), a sprinkler (not shown) can be used to make the water splash in front of the audience.

This effect is actually watching a movie, but the effect is the same as being in a play. Image, audio and special effects control device according to the present invention can implement such a three-dimensional stereoscopic image.

Since the laser generating means 150 is coupled thereto, it is possible to further emphasize the three-dimensional effect. That is, the laser generating means 150 can control the laser in various ways. The airship (not shown) flying through space through the laser can be controlled through the projector 10 and the laser generating means 150.

5 is a flowchart illustrating a method for integrated video, audio and special effects control according to the present invention. As shown in Fig. 5, since the procedure proceeds in accordance with the time code 5, the central computer 100 should be ready to read the time code 5.

First, the central computer 100 must proceed to read and store the data of the time code (S10). Of course, a master tape (not shown) must be prepared to record the final program before the start of this storage operation. The entire time of the master tape is recorded using a basic or edit black signal without gaps or discontinuities in the signal. At this time, the recorded time code 5 serves as a criterion for distinguishing each frame of the final program.

Next, the contents of the cue sheet are input to a memory (not shown) of the central computer 100 using a keyboard (not shown). If there is no abnormality in the contents of the cue sheet, the central computer 100 controls the apparatus for displaying all video, audio and special effects based on the time code 5. All the devices used for such recording and storage are synchronized with the central computer 100 to perform a batch control before reading and storing the batch control. In this case, accurate editing is performed in units of frames.

When the preparation is completed, a check is performed to check whether the input is properly performed through the playback process. Image, audio and special effects control apparatus according to the present invention can control all devices including the projector 10, the lighting means 20, the special effect generating means (40).

 In this case, the editing operation may be performed simultaneously with the video and audio, or the video recording may be edited after the video editing is completed. In the case of voice editing using the time code 5, it is possible to accurately edit the syllable unit.

The time code generator is, as the name implies, a device that generates a digital time code 5 signal. The timecode generator has a timecode display on the front panel and a switch to preset the start point of the timecode. There is a terminal for remote control of running and stationary time code.

In order for the timecode 5 to perform work in accordance with each frame, the timecode generator must be synchronized with the cue sheet data (S20). The video, audio and special effects control apparatus according to the present invention share the synchronization signal generator, and simply supply the synchronization signal to the time code generator.

These timecode generators allow you to choose from a variety of frame rates. The video, audio and special effects control device according to the present invention selects an NTSC rate of 29.97 frames per second (fps).

And because this timecode can be controlled remotely, this can be done automatically.

When the time code generator is synchronized with the cue sheet data as described above, the operation of reading the time code 5 is performed (S30). There are several ways to read the timecode. If the time code 5 is read at a too slow speed, a problem occurs when driving. In addition, when traveling at high speed, a thin air film is formed between the timecode reader and the tape, which causes a problem in reading.

As such, when the time code generator starts reading the cue sheet data, the video, audio and special effects control device starts the operation of the video, audio and special effects control device according to the edited contents of the cue sheet (S40). After all the contents of the cuesheet have been recorded in this way, the work on the video, audio and special effects control devices is finished.

Using SMPTE timecode in this way makes it possible to remotely control various devices wirelessly.
