Special Effects Synchronizer and 4D Screening System {APPARATUS FOR SYNCHRONIZING OF SPECIAL EFFECT AND 4D PROJECTING STSTEM}

The present invention relates to a special effect synchronizer and a 4D screening system, and more particularly, to a special effect synchronizer and a 4D screening system capable of reliably synchronizing a special effect given in relation to image data being screened.

A 4D movie (4D movie) refers to a movie that gives a physical effect when an effect occurs on a certain image in the movie. The 4D screening system is a device that provides realistic images by moving chairs in accordance with the images or by using wind, fog, and lights to provide realistic images. It is introduced to simulation equipment and theater screening systems to provide realistic images. .

The 4D screening system controls the motion and special effects of the chair and the like according to the video, and the video and the special effects equipment are synchronized. Looking at the synchronization control at this time, the control signal is received by the GPO terminal or the RS-232 terminal when the video starts. That is, the synchronization control unit receives a signal indicating the start of the image from the screening server that reproduces and displays the image data, and operates its own timer to synchronize the special effect to the image.

In this way, synchronization at the start is reliable, but it is difficult to reliably synchronize over time. In particular, when the video is reproduced many times, such a phenomenon is prominent, and thus, synchronization correction is required for maintenance.

On the other hand, in general, the projection server outputs the video data using the HD-SDI port. Video data transmitted through the HD-SDI port includes a time code (TC), which is commonly used to synchronize video and other special effects and sound data.

However, in some cases, HD-SDI signals are converted and used for special purposes. For example, an HD-SDI signal may be converted into a high definition multimedia interface (HDMI) or an SDI or composite signal.

Hereinafter, the special effect synchronizer and the 4D image system of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram showing a special effect synchronizer of the present invention.

The special effect synchronizer shown in FIG. 1 includes a table storage unit 110 for storing an effect table including a time code of image data and special effect information applied to the time code, and a current time code of the image data being displayed. And an information extraction unit 120 for extracting special effect information provided to the time code of the matching effect table.

The table storage unit 110 stores the effect table. The effect table is composed of time code of the video data and special effect information provided corresponding to the time code.

2 is a schematic diagram showing an effect table.

The time code is written for each frame, and about 30 frames are used for 1 second screening. However, the time code is briefly illustrated in FIG. The time code in the upper row represents time, with 1 representing 1 second, 2 representing 2 seconds, and n representing n seconds. Information for controlling the special effects is disposed in the special effect information in the lower row.

A time code is a time code that is recorded on the edge of a film in a movie, such as with a crystal sink system. In movies using digital data, the time code is embedded in the digital data.

The special effect information includes signals for controlling special effect devices such as a driving device for moving a seat, a water jet device for spraying water, a wind jet device for jetting wind, and a fog device for generating fog. That is, it controls whether or not each special effect device is driven, and controls the degree of driving at the time of driving, for example, the injection amount of water, the amount of fog generated, the direction of movement of the seat and the like.

The special effect information is written / embedded in a form corresponding to the time code by the user, and may be generated by a means for writing the special effect information, for example, in the table generator 130.

The table generator 130 generates an effect table and transmits the effect table to the table storage unit 110. In this case, the effect table may take the form of user-editable software.

3 is a schematic diagram showing an execution state of the table generation unit 130 implemented in the form of software.

As shown, the special effect devices to be controlled are listed on the left, a time code at the bottom, and a driving time at the center. The time code of the effect table can be obtained by analyzing the entire time code of the image data before screening. Alternatively, the first time code and the last time code of the video data may be used. In the latter case, the time codes between the first time code and the last time code can be obtained by equally dividing the first time code and the last time code.

In the table generator of FIG. 3, the special effect apparatus and the driving time are separately shown for the user's convenience. The special effect information includes a driving time and a special effect device to be driven during the driving time, and in some cases, may include a driving method.

The time code stored in the effect table may be a time code to which special effect information is assigned. There are usually sections in which a special effect device is not driven when showing a movie. This section corresponds to a time code to which no special effect information is assigned in the effect table, and may not be stored. By using this, the storage capacity of the table storage unit 110 may be saved.

The information extractor 120 extracts, from the table storage 110, an effect table generated for synchronizing special effects with the image data when predetermined image data is displayed. Then, the time code matching the current time code included in the frame of the image data output at the present time is searched in the extracted effect table, and the special effect information applied to the searched time code is extracted.

The extracted special effect information exactly matches the time code of the currently output frame, thus enabling reliable synchronization. For example, even if the output of the image data is partially delayed due to an error of the image system, special effect information corresponding to the current time code is extracted as a result. In the case of implementing a special effect using a conventional start signal as its own timer, according to this example, the special effect information is extracted by a delay time before the current time code. Therefore, the image data to be displayed and the special effect device is not synchronized, but according to the configuration of the present invention there is no such problem.

Meanwhile, the special effect synchronizer of the present invention may further include an information transmitter 140 for transmitting the special effect information extracted by the information extractor to the special effect device. The information transmitting unit 140 transmits the special effect information to the special effect device through the wired or wireless network. At this time, the special effect device should be provided with a communication means capable of communicating with the information transmitting unit 140.

In order for the information extraction unit 120 to operate normally, not only an effect table that can be provided from the table storage unit 110 but also a current time code of image data being displayed is required. Synchronization of a special effect means synchronization with video data currently being played. Therefore, in order to synchronize with the current image data, the current time code, which is a time code included in a frame of the image data currently output, must be transmitted from the screening server that is displaying the image data.

To this end, the special effect synchronizer may further include a code receiver 150 which receives the current time code from the screening server 200 displaying the image data and provides the current time code to the information extracting unit.

If the screening server provides a HD-SDI (HD-Serial Digital Interface) signal containing the time code instead of transmitting the time code, the time code should be extracted from the special effect synchronizer. In this case, the code receiver 150 may transmit a request signal to the signal receiver 160 or the code converter 180 as necessary.

To this end, the special effect synchronizer includes a signal receiving unit 160 for receiving an HD-SDI signal (HD-Serial Digital Interface) from the screening server 200 displaying the image data,

The apparatus further includes a code converter 180 for converting an HD-SDI signal into an HDMI or SDI and composite signal, and a code extractor 170 for extracting a current time code included in the received HD-SDI signal and providing the extracted information to an information extractor. can do.

In this way, HD-SDI signals can be converted to HDMI or SDI and composite signals, and processed to achieve more accurate synchronization.

The HD-SDI signal may be output from a beam projector that receives image data from the screening server and projects the image data. Accordingly, the signal receiver may receive the HD-SDI signal from at least one of the screening server and the beam projector.

In FIG. 1, the screening server outputs an HD-SDI signal, and receives the signal from the signal receiver 160 and transmits the signal to the code converter 180.

In addition, the code conversion unit 180 converts the HD-SDI signal into an HDMI or SDI and composite signal, and then transfers the HD-SDI signal to the code extraction unit 170. The HD-SDI signal includes a timecode with the video, and the converted HDMI or SDI and composite signals also include the timecode.

Next, the code extractor 170 extracts the time code information and transmits the extracted time code information to the information extracting unit 120. The collected time code and the special effect information stored in the table storage unit 110 are collected and screened. At the same time, the 4D system is synchronized.

According to the above configuration, the current time code transmitted from the screening server is received and provided to the information extraction unit, or the HD-SDI signal transmitted from at least one of the screening server or the beam projector is converted into HDMI, SDI, Composite to convert the current time code. It can be extracted and provided to the information extraction unit.

After receiving the current time code, the information extracting unit loads the effect table corresponding to the image data currently being displayed in the table storage unit 110 and searches for a time code corresponding to the current time code among time codes included in the effect table. Then, the special effect information attached to the searched time code is extracted. Of course, if no special effect information is provided in the searched time code, no special effect information is extracted.

The extracted special effect information is transmitted to the special effect device through the information transmitter, and the special effect device that receives the special effect information drives the special effect that is in charge of the user according to the special effect information.

The table storage unit 110 may store an effect table corresponding to a plurality of image data. In this case, in order to load an effect table corresponding to the image data currently being displayed, an identifier of the image data being displayed may be received from the screening server. Of course, the effect table should also contain the identifier at this time. At this time, the identifier may be a name of the video data, an arbitrarily assigned unique number, or the like. In this case, the code receiving unit 150 or the signal receiving unit 160 may receive an identifier from the screening server 200 and transmit the identifier to the information extracting unit 120. The information extracting unit 120 extracts an effect table including a matching identifier among a plurality of effect tables using the received identifier.

Such a configuration may be variously modified. If the screening server provides an HD-SDI (HD-Serial Digital Interface) signal including a time code instead of transmitting a time code, the code receiver 150 may receive a signal receiver ( 160 or the code conversion unit 180 may be operated to extract the time code.

In some cases, the screening server 200 may provide an HDMI, SDI, or Composite signal including the time code instead of transmitting the time code. In this case, the code conversion unit 180 does not need to convert the code. Transfer immediately, the code extractor 170 may extract the code.

In addition, various modifications are possible.
