Bright light display synchronization system and method

The present invention relates to a display system; in particular, it relates to a system and method for display synchronization of bright lights.

The existing bright light system is installed on the bright lamp post or the bright light wall, and multiple electronic nameplates are installed at different positions on the blessing lamppost or light wall, and the playback screen displayed by the marquee is played on different electronic nameplates to display the length For blessing information with the same number of pages, when the playback progress of each electronic signage is the same, the displayed status will be the same.

However, because the above-mentioned bright light system does not have a design to display the progress simultaneously, when some bright lights receive the light-seeking command to pause the playback screen at a specific information and then re-display it, the display progress of some electronic nameplates will be different from that of other electronic nameplates. The problem of different display progress makes the playback screens on the entire bright lamp post or lamp wall different, which seems very chaotic.

In view of this, the purpose of the present invention is to provide a system and method for synchronizing the display screens of the marquee, so that the display screens displayed by different electronic nameplates can be played at the same pace in accordance with the same standard, so that the display screens of the electronic nameplates are neat and tidy. Draw an orderly.

To achieve the above object, the present invention provides a light display synchronization system, which includes a main control module and more than one light light modules electrically connected to the main control module. The main control module is used for broadcasting a synchronous signal, and the synchronous signal provides a standard display progress. The bright light module has a control unit, which is electrically connected to and controls an electronic nameplate to repeatedly play a playback picture of a marquee; when the bright light module receives the synchronous signal, the control unit will receive the synchronous signal. The display progress of the display screen played by the electronic nameplate is compared with the standard display progress of the synchronization signal. If it is synchronized, it will not be processed. If it is ahead of time, the time for each subsequent playback of the playback screen will be extended. If it is behind, the time for each subsequent playback will be shortened. The time of the play picture is until the display progress of the play picture is synchronized with the standard display progress of the synchronization signal.

In order to achieve the above object, the present invention provides a method for synchronizing the display of bright lights, the steps of which include: setting up more than one bright light module, and using their electronic nameplates to repeatedly play a playback picture of a marquee. The light module receives a synchronous signal with standard display progress. Compare the display progress of the display screen played by the electronic nameplate at the time of receiving the synchronization signal with the standard display progress of the synchronization signal. If it is synchronized, it will not be dealt with. Then shorten the time for playing the playback picture each time until the display progress of the playback picture is synchronized with the standard display progress of the synchronization signal.

The effect of the present invention is that the display progress can be aligned with the synchronous signal broadcast by the main control module, so that the electronic nameplate of the bright light module can replay the original playback screen again after being inserted into other light-seeking tasks or paused and interrupted. By means of the synchronization signal standard, it can be synchronized with the display progress of other bright light modules, so that the display screens of the electronic nameplates installed on the bright light poles or bright light walls can be neatly drawn and orderly.

In order to illustrate the present invention more clearly, preferred embodiments are given and detailed descriptions are given below in conjunction with drawings. Please refer to Fig. 1 to Fig. 2, which is a bright light display synchronization system 100 according to the first preferred embodiment of the present invention, which includes a main control module 10 and more than one main control module 10 connected in series or in parallel. The bright lamp modules 20 electrically connected, in this preferred embodiment, are provided with a plurality of bright lamp modules 20, the main control module 10 is used to broadcast a synchronous signal A, and each bright lamp module 20 is connected in series When the main control module 10 broadcasts the synchronous signal A, each light module 20 connected in series receives the synchronous signal A almost at the same time, and each synchronous signal A provides a standard display progress A1 information.

The bright light module 20 has a control unit 22, the control unit 22 is electrically connected to and controls an electronic nameplate 24, so that the electronic nameplate 24 repeatedly plays a playback screen 241 of a marquee, and the playback screen 241 includes more than one page of information Content, such as the play screen 241 in this preferred embodiment includes four pages of information content, the information content of the four pages is the display content of name, address, prayer word 1, and prayer word 2 in sequence, displayed on different electronic nameplates The length of the information content of the play screen 241 of 24 is the same as the number of pages, but the specific details of the information content are customized according to the different believers and different prayer needs.

When the bright light module 20 receives the synchronous signal A broadcasted, the control unit 22 will receive the synchronous signal A and the electronic nameplate 24 will play the display of the playing screen 241 The progress is compared with the standard display progress A1 of the synchronous signal A. If it is synchronous, it will not be processed; if the playing picture 241 is ahead, the time for playing the playing picture 241 will be extended each time; if the playing picture 241 is lagging behind, it will be shortened. Each time the playback picture 241 is played, until the display progress of the playback picture 241 is aligned backwards or catches up with the standard display progress A1 forward, so that the display progress of the playback picture 241 is consistent with the standard display progress A1 of the synchronization signal A until sync.

The content of the above-mentioned first preferred embodiment is further described. Please refer to Figures 1 to 2, according to the total number of frames played or the total number of seconds played, the length of the play screen 241 is divided into multiple counting units B, and the standard display broadcast by the main control module 10 The unit used by the progress A1 is the same as the count unit B of the play screen 241 . In the first preferred embodiment, the total number of frames of the playback picture 241 is divided into 100 counting units B starting from frame 0 (frame 0) and ending at frame 99 (frame 99). The standard display progress A1 of the synchronization signal A broadcast by the module 10 is frame 0.

The difference between the display progress of the electronic nameplate 24 when receiving the synchronization signal A and the standard display progress A1 of the synchronization signal A is defined as a synchronization difference. In this preferred embodiment, the display progress is 30 frames (frame 30), so the synchronization difference is 30 counting units B, that is, 30 frames. The judging method for comparing and judging whether the playing picture 241 is ahead or behind is, if the synchronization difference is less than 1/2 of the length of the playing picture, it is judged to be ahead; if the synchronization difference is greater than or equal to half of the length of the playing picture One of them is judged as backward.

Because the synchronization difference is 30 frames, which is less than 50 frames of 1/2 of the playing picture 241, it is judged to be ahead of time, and prolongs the moving time of playing the playing picture 241 each time in the future until the playing picture 241 is made until the display progress of the synchronization signal A is synchronized with the standard display progress A1. For example, when the moving time is set to be 5 frames, after 6 times of extended play screen 241, the display progress of the play screen 241 will be consistent with the standard of the synchronization signal A. The display progress A1 is synchronized, and the playing time of playing the playing picture 241 will return to the original unextended or shortened time after synchronization.

In other preferred embodiments, if the synchronous difference after the comparison is 70 frames, which is greater than 50 frames of 1/2 of the playback picture 241, it will be judged as lagging behind and reduce the amount of time played each time in the future. The playing picture 241 moves time until the display progress of the playing picture 241 is synchronized with the standard display progress A1 of the synchronous signal A. The moving time is set to 5 frames, and then 6 times of shortened playing pictures are passed. After 241, the display progress of the play picture 241 will be synchronized with the standard display progress A1 of the synchronization signal A, and the time for playing the play picture 241 will return to the original time that was not extended or shortened after synchronization.

The moving time of above-mentioned extension or reduction is except the time of 5 frames, also can be set as the moving time of 10 frames or 30 frames, can after receiving the synchronous signal A that this main control module 10 broadcasts like this and then 3 The display progress of the play screen 241 is synchronized with the standard display progress A1 of the synchronization signal A in one or only one play cycle. However, it should be noted that the longer the extension time is set, the more abrupt and uneven the process of looping the playing picture 241 will be.

When the extended or reduced moving time is a fixed value, for example, in another preferred embodiment, three bright lamp modules 20 are electrically connected to the main control module 10, and the electronic components of these bright lamp modules 20 The nameplate 24 displays the display progress of the playing screen 241 , which is 5 frames ahead, 5 frames behind and 20 frames ahead of the synchronization signal A broadcast by the main control module 10 . If the moving time is set to the time of 5 frames of a fixed value, the first play cycle after judging whether it is ahead or behind, the display progress of the first and the electronic nameplate 24 of the second bright light module 20 will be Synchronized with the standard display progress A1 of the synchronous signal A, and the electronic nameplate 24 of the third bright lamp module 20 is expected to play the cycle of the next playback picture 241, that is, when the second cycle is played after judging whether it is ahead or behind, The synchronization with the standard display progress A1 of the synchronization signal A is achieved.

The synchronous difference of different bright lamp modules 20 can be set according to the degree of deviation of the synchronous difference. The synchronous difference corresponding to the greater degree of deviation can be set to a larger moving time, and the synchronous difference corresponding to the smaller degree of deviation can be set to be shorter. Decimal value for movement time. And the moving time of each extension or reduction is outside the setting of equal length, and the moving time can also be set as closer to or catch up with the standard display progress A1, then extend or shorten the less moving time, so that the playing screen 241 Looping to sync is smoother.

In addition, the extended or shortened moving time can selectively extend or shorten the playing time of the playing screen 241 on each page of information content. For example, in the above-mentioned first preferred embodiment, the moving time is extended or shortened in the electronic The time for the nameplate 24 to play the information content of the first page is to extend or shorten the time for the electronic nameplate 24 to play the information content of the name. In other preferred embodiments, the moving time can also be extended or shortened when the electronic nameplate 24 plays the last page of information content, that is, the time for the electronic nameplate 24 to play the information content of the second prayer.

In the above-mentioned first preferred embodiment, the length of the playing picture 241 is divided into counting units B of a plurality of frame numbers, and in other preferred embodiments, the length of the playing picture 241 can also be expressed as the total number of seconds Distinguishes counting unit B divided into seconds. For example, the total number of seconds of the playing screen 241 is divided into counting units B of 100 seconds from 0 seconds to 100 seconds, and the standard display progress A1 of the synchronization signal A broadcast by the main control module 10 is 0 seconds; When the display progress of the two different bright light modules 20 is 30 seconds or 70 seconds, the synchronization difference is the counting unit B of 30 seconds or 70 seconds, respectively.

If 1/2 of the play screen 241 is used as the criterion for judging ahead or behind, the situation of 30 seconds and 70 seconds of synchronization difference can be judged as being ahead and behind respectively. Playing the playing picture 241 one movement time for the first time reduces the same moving time of playing the playing picture 241 every time the second light lamp module 20 plays the future. If will move The time is all set to 5 seconds, and after 6 times of extended playing screens 241, the display progress of the play screens 241 of the two bright light modules 20 will be synchronized with the standard display progress A1 of the synchronization signal A respectively. The time for each light module 20 to play the playing picture 241 will return to the original unextended or shortened time.

The above-mentioned counting unit B is the number of seconds, and the moving time in the embodiment is a fixed value, but in this embodiment, different bright lamp modules 20 can have different moving time settings, or different bright lamp modules 20 can be synchronized The degree of deviation of the difference may correspond to a larger or smaller change in the moving time, which is the same as the way in which the moving time can be changed in the above-mentioned first preferred embodiment.

The present invention judges whether the play screen 241 of each bright light module 20 is ahead or behind. In addition to using half of the total length of the play screen 241 as the standard for judging ahead or behind, please refer to Figures 3 to 4. In the second preferred embodiment shown, the total length of the playback screen 241 can also be divided into four parts, which are respectively less than a quarter of the playback screen 241, greater than or equal to a quarter of the playback screen 241 and smaller than the playback screen One-half of the playing picture 241, greater than or equal to one-half of the playing picture 241 less than three-quarters of the playing picture 241, and greater than or equal to three-quarters of the playing picture 241.

The standard display progress A1 of the synchronous signal A broadcast by the main control module 10 is 0 seconds. When the light module 20 receives the synchronous signal A broadcasted, the control unit 22 will receive the synchronous signal A. The display progress of the nameplate 24 playing the playing screen 241 is compared with the standard display progress A1 of the synchronization signal A to obtain a synchronization difference.

The way of judging whether it is ahead or behind is that if the synchronization difference is less than 1/4 of the play picture 241, it is judged as ahead; if the synchronization difference is greater than or equal to 1/4 of the play picture 241 and less than 2 One-third of the time is judged to be particularly advanced, if the synchronization difference is greater than or equal to one-half of the play picture 241 and less than three-quarters of the play picture 241, it is judged to be particularly behind, if the synchronization difference is greater than or equal to the play Three-quarters of the screen 241 is judged to be behind.

When it is judged to be ahead of time, then prolong the playing of the playing picture 241-the first moving time at a time; when it is judged to be particularly ahead of time, it will prolong the playing of the playing picture 241-the second moving time; The play picture 241-the third moving time, when judged as lagging behind, then shorten each play of the playing picture 241-the fourth moving time, and the second moving time is greater than the first moving time, the third moving time is greater than the fourth moving time, The time points for the final synchronization of the playing screens 241 of each different bright light module 20 can tend to be consistent.

For example, for the two bright light modules 20 in this preferred embodiment, please refer to FIG. 3A , the first bright light module 20 receives the synchronization signal A and the display progress of the electronic nameplate 24 playing the playing screen 241 at the moment It is 60 seconds, and the synchronous difference with 0 seconds is 60 counting units B, that is, 60 seconds, and this number of seconds falls to be greater than or equal to 1/2 (50 seconds) of the playing picture 241 and less than a quarter of the playing picture 241 The numerical value of the third (75 seconds), so it is judged to be particularly backward, the third moving time of shortening the playing picture 241 to be played back is set to 10 seconds, and after the playing picture 241 of shortening the time 4 times, the first light The display progress of the play screen 241 of the light module 20 is synchronized with the standard display progress A1 of the synchronization signal A.

Please refer to FIG. 3B , when the second bright light module 20 receives the synchronization signal A, the display progress of the electronic nameplate 24 playing the playback screen 241 is 80 seconds, and the synchronization difference from 0 seconds is 80 counting units B , which is 80 seconds, this number of seconds is greater than or equal to the playback picture Three-quarters (75 seconds) of the value of surface 241, therefore judged to be lagging behind, the 4th movement time that will shorten this playing picture 241 and play back is set as less than 5 seconds of above-mentioned 3rd movement time, then through 4 times of shortening After the playing picture 241 of the time, the display progress of the playing picture 241 of the second bright light module 20 will be synchronized with the standard display progress A1 of the synchronization signal A, and the first and second bright light modules 20 and The standard shows that the synchronization time of the progress A1 is the same, and after the synchronization, the time for each bright light module 20 to play the playing picture 241 will return to the original unextended or shortened time.
