In this case, each module or combinations of modules may be implemented as the mobile terminal 200 . However, the present embodiment is not limited thereto.

3 is a block diagram for explaining in detail the structure of the light rod of FIG. 1 .

Referring to FIG. 3 , the light stick 300 may include a communication unit 310 , a light emitting unit 320 , a control unit 330 , a power supply unit 340 , and a button unit 350 .

The communication unit 310 may communicate with the mobile terminal 200 . The communication unit 310 may establish communication with the mobile terminal 200 using a short-range communication technology. The communication unit 310 may receive the control data Dc from the mobile terminal 200 . The communication unit 310 may transmit the control data Dc to the control unit 330 .

However, the present embodiment is not limited thereto.

The controller 330 may control the color and flickering of the light of the light emitting unit 320 . The controller 330 may operate in at least two modes, a first mode and a second mode. The first mode may be a mode in which the light emitting unit 320 is controlled through the control data Dc, and the second mode may be a mode in which the light emitting unit 320 is controlled by the control button 352 .

In the first mode, the control unit 330 may receive the control data Dc from the communication unit 310 . The controller 330 may control the color and blinking of the light of the light emitting unit 320 by using the control data Dc.

In the second mode, the control unit 330 may control the light emitting unit 320 according to the color change and blinking pattern of the light preset by the control button 352 of the button unit 350 .

The button unit 350 may include a mode change button 351 and a control button 352 . The mode change button 351 may be operated in any one of an off state, a first mode state, and a second mode state. When the mode change button 351 is in an off state, power supply from the power supply unit 340 may be cut off. Accordingly, the power of the light rod 300 may be turned off.

When the mode change button 351 is in the first mode state, the communication unit 310 may attempt to connect to the mobile terminal 200 using a short-range wireless technology. For example, the communication unit 310 may attempt Bluetooth pairing with the mobile terminal. When the communication unit 310 is connected to the mobile terminal 200 and receives the control data Dc, the control unit 330 may receive the control data Dc to control the light emitting unit 320 .

However, the present embodiment is not limited thereto.

Although only two buttons of the mode change button 351 and the control button 352 are included in the button unit 350 in FIG. 3 , the present embodiment is not limited thereto.

4 is a flowchart illustrating a method for controlling a light stick color according to some embodiments of the present invention.

Referring to FIG. 4 , the video content is accessed ( S110 ).

Specifically, referring to FIG. 1 , video content may be provided to the mobile terminal 200 by the streaming server 100 . The mobile terminal 200 may access the video content provided by the streaming server 100 through an application or program.

Again, referring to FIG. 4 , the reception of the lighting control time series data starts ( S120 ).

Specifically, referring to FIG. 1 , the lighting control time series data Dn may be automatically received within the video content or upon a user's request. Alternatively, the lighting control time-series data (Dn) may have already been received from the previously accessed video content. In this case, the step of receiving the lighting control time series data (Dn) may be omitted.

Again, referring to FIG. 4 , it is determined whether it is connected to the light stick (S130).

Specifically, referring to FIG. 1 , when the light stick 300 and the mobile terminal 200 are not connected to each other, they may wait until they are connected. When the light stick 300 and the mobile terminal 200 are connected to each other, the following procedure may be performed.

Again, referring to FIG. 4 , it is determined whether the reception of the lighting control time series data is complete ( S140 ).

Specifically, referring to FIG. 1 , the lighting control time series data Dn may be received from the streaming server 100 . If the reception of the lighting control time series data Dn is not completed, it may wait until it is completed. When the reception of the lighting control time series data Dn is completed, the following procedure is performed.

Again, referring to FIG. 4 , video streaming is started ( S150 ).

Specifically, referring to FIG. 1 , the mobile terminal 200 may receive streaming data Dv from the streaming server 100 to play, that is, stream a video. In the video streaming, the reception of the streaming data Dv and the reproduction of the video are performed in parallel, and the streaming data Dv corresponding to the reproduced video part must be received in the mobile terminal 200 in advance prior to the video reproduction.

Again, referring to FIG. 4 , video streaming is started ( S150 ).

Specifically, referring to FIG. 1 , the mobile terminal 200 may receive streaming data Dv from the streaming server 100 to play, that is, stream a video. In the video streaming, the reception of the streaming data Dv and the reproduction of the video are performed in parallel, and the streaming data Dv corresponding to the reproduced video part must be received in the mobile terminal 200 in advance prior to the video reproduction.

Again, referring to FIG. 4 , control data according to a video playback time is generated ( S160 ).

Specifically, referring to FIG. 1 , the mobile terminal 200 may check the playback time of a video currently being played in the mobile terminal 200 , and generate control data Dc according thereto. The lighting control time series data Dn is data synchronized with the streaming data Dv, and color data according to a video playback time may be arranged. Accordingly, the mobile terminal 200 may convert the color data corresponding to the video playback time into the control data Dc.

In this case, the mobile terminal 200 may convert the color data of the lighting control time series data (Dn) into the control data (Dc) in real time at the video playback time. In this case, since the conversion itself is performed immediately, an additional operation is not required, and thus the speed of the entire operation may be increased.

Alternatively, the mobile terminal 200 may convert the color data of the lighting control time series data (Dn) into the control data (Dc) by using a delay call by securing the buffer time from the video playback time. In this case, since the synchronization between the video reproduction and the conversion of the control data Dc is calculated in advance, the possibility of synchronization failure can be minimized. How to use the buffer time will be described in more detail later.

Again, referring to FIG. 4 , control data is transmitted to the light stick (S170).

Specifically, referring to FIG. 1 , the mobile terminal 200 may transmit the control data Dc to the light stick 300 through short-range communication technology.

Hereinafter, a lightstick color control method using a buffer time will be described with reference to FIGS. 4 to 10 .

FIG. 5 is a flowchart for explaining in detail the control data generation step of FIG. 4 , and FIGS. 6 to 10 are intermediate steps for explaining the control data generation step of FIG. 4 in detail. Hereinafter, step S160 of FIG. 4 will be described in detail with reference to FIGS. 5 to 10 .

Referring to FIG. 5 , a video playback time is received ( S161 ).

Specifically, referring to FIG. 6 , the current playback time may be checked. The current playback time can be continued as time passes.

Again, referring to FIG. 5, the lighting control time series data of the first future time closest to the video playback time is searched (S162).

Specifically, referring to FIG. 6 , the lighting control time series data Dn may have a unit time. 6 exemplarily shows the unit time as 1 second (1s). However, the present embodiment is not limited thereto. The lighting control time series data Dn may include color data for each unit time.

The first future time T1 may be any one of the times corresponding to the unit time of the lighting control time series data Dn. The first future time T1 may be located in the future from the current playback time of the video. The first future time T1 may be a unit time of the nearest future from the current playback time of the video.

Again, referring to FIG. 5, the lighting control time series data for the buffer time of the first time from the first future time is stored in advance (S163).

Specifically, referring to FIG. 7 , the buffer time Tb may be set by the first time P1 from the first future time T1 . Lighting control time series data (Dn) for the buffer time (Tb) may be stored in advance in the mobile terminal (200). At this time, “store” means to be stored in the memory for conversion of the control data Dc, and may have a different meaning from that received from the streaming server 100 to the mobile terminal 200 .

The reason for storing the buffer time (Tb) in advance is that it is necessary to set a delay call in advance in order to accurately synchronize the video and the lighting control time series data. The buffer time Tb may be reduced as the current playback time is changed. Accordingly, when the buffer time Tb is reduced by the predetermined minimum buffer time, the buffer time Tb may be increased back to the first time P1.

In this case, the first time P1 may mean an initial time before the buffer time Tb is reduced. As the first time P1 is set to be larger, the number of operations to increase the buffer time Tb may decrease, and thus the amount of calculation may be reduced. Conversely, as the first time P1 is set smaller, the amount of calculation may increase. However, when the first time P1 is set too large, the probability of out of synchronization between the delayed call and the playback time of the moving picture, that is, the streaming data Dv, may increase.

Accordingly, the first time P1 should be set to an appropriate size that is neither too large nor too small. For example, the first time P1 may be 2 seconds to 3 seconds, but the present embodiment is not limited thereto.

Again, referring to FIG. 5, a delayed call is reserved for color data located within the buffer time (S164).

Specifically, referring to FIG. 7 , the first delay time TL1 with respect to the unit time in which the color data is located is calculated based on the current reproduction time. A delayed call may be reserved using the calculated first delay time TL1. That is, color data between 3 seconds and 4 seconds after the first delay time TL1 based on the current playback time may be called with a delay. Here, “call” means that it is loaded to be converted into the control data Dc. Through this delayed call method, streaming data (Dv) for video playback and lighting control time series data (Dn) can be synchronized.

Again, referring to FIG. 5, it is determined whether the buffer time is greater than the minimum buffer time (S165).

If the buffer time is greater than or equal to the minimum buffer time, the delayed-called color data is converted into control data (S167).

Specifically, referring to FIGS. 7 and 8 , as the current playback time progresses, the buffer time Tb may decrease in size from the first time P1 to the second time P2 . However, the second time P2 may be greater than or equal to the preset minimum buffer time. Accordingly, the color data located therein may be continuously converted into the control data Dc without changing the size of the buffer time Tb.

Referring again to FIG. 5 , if the buffer time is less than the minimum buffer time, the buffer time of the delayed-called color data is extended to the first time ( S166 ). Next, a delayed call is reserved for the color data located within the buffer time again (S164).

Specifically, referring to FIGS. 9 and 10 , the third time P3 may be smaller than a preset minimum buffer time. Accordingly, the buffer time Tb may be extended to the size of the first time P1 again. As the current playback time progresses, the first delay time TL1 may also decrease. Also, as the buffer time Tb is extended, a second delay time TL2 for color data between 5 seconds and 6 seconds may be calculated. A delayed call may be reserved using the calculated second delay time TL2. That is, color data of 5 to 6 seconds after the second delay time TL2 based on the current playback time may be called with a delay.

In this way, delayed calling of color data located at 3 seconds to 4 seconds, 5 seconds to 6 seconds, and 7 seconds to 8 seconds can be performed in synchronization with video playback.
