The methods of making and using various embodiments of the present invention are discussed in detail below. However, it is to be noted that many of the possible inventive concepts provided by the present invention can be implemented in various specific ranges. These specific examples are merely illustrative of the methods of making and using the invention, but are not intended to limit the scope of the invention.

1 is a video playback system 100 according to the present invention including a server 101 and at least one 3D glasses 110 having a billing function. For example, the server 101 is a server of a movie theater, but is not limited thereto. The 3D glasses 110 includes a controller 112, a switch 122, a left shutter 114, a right shutter 116, a detector 118, a transmitter 120, and a storage device 124. The controller 112 is configured to receive a control signal S1 transmitted by the server 101 from the theater. The control signal S1 includes a left shutter driving signal and a right shutter driving signal. The left shutter 114 and the right shutter 116 of the 3D glasses 110 perform left and right eye switching operations of the 3D glasses 110 according to the left shutter driving signal and the right shutter driving signal. The switch 122 is configured to generate a mode selection signal. For example, when the switch 122 is in a first state, the mode selection signal is used to indicate a 3D mode; when the switch 122 is in a second state, the mode selection signal is used to indicate A 2D mode. When the mode selection signal is switched to the 3D mode, the left shutter 114 and the right shutter 116 of the 3D glasses 110 are directly actuated according to the control signal S1 of the server 101 (ie, the left shutter 114 and the right shutter 116 are alternately turned on). For example, when the left and right shutter drive signals of the control signal S1 are respectively turned on (for example, high level) and turned off (for example, low level), the left shutter 114 and the right shutter 116 are respectively turned on and off; when the control signal is When the left and right shutter drive signals of S1 are respectively turned off and on, the left shutter 114 and the right shutter 116 are respectively closed and opened. Conversely, when the mode selection signal is switched to the 2D mode, if the left shutter drive signal of the control signal S1 is turned on, the left shutter 114 and the right shutter 116 of the 3D glasses 110 are simultaneously turned on, if the right shutter drive signal of the control signal S1 is turned on. The left shutter 114 and the right shutter 116 of the 3D glasses 110 are simultaneously closed. In addition, the left shutter 114 and the right shutter 116 can also be simultaneously turned on when the right shutter drive signal of the control signal S1 is on, and simultaneously turned off when the left shutter drive signal is on.

The detector 118 is configured to determine whether the left and right eye switching actions of the 3D glasses 110 are activated according to the control signal S1, and generate a mode determination signal S2 for indicating that the 3D glasses 110 operate in the 2D mode or the 3D mode. The mode determination signal S2 can be transmitted back to the server 101 via the transmitter 120 or stored to the storage device 124 first. The server 101 determines a charging mode based on the mode determination signal S2. For example, in an embodiment, the server 101 may determine the charging mode according to the mode determination signal S2 returned by the transmitter 120 during the movie playing. In another embodiment, the server 101 can obtain the mode determination signal S2 stored in the storage device 124 by a reading device after the movie is played, and then determine the charging mode. When the mode determination signal S2 is in the 3D mode, the server 101 performs charging at a first rate, whereas when the mode determination signal S2 is in the 2D mode, the server 101 performs charging at a second rate. In addition, the 3D glasses 110 may also include a timer 126 for accumulating the time during which the 3D glasses 110 operate in the 3D mode and the 2D mode.

Figure 2 shows a 3D charging method using the 3D glasses 110 disclosed in Figure 1. As shown in step S20, when the user enters the movie theater to view the movie with the 3D content, the movie played by the movie theater can be selected by the switch 122 on the 3D glasses 110 of the present invention, and the movie is played by the step 2D mode or the 3D mode. The judging mechanism shown in S22, that is, the judging mechanism disclosed in the 3D charging method of the present invention discriminates that the user operates the 3D glasses 110 disclosed in the present invention in the 2D or 3D mode. After the 3D glasses 110 are operated in the 2D or 3D mode, a mode determination signal S2 is generated and transmitted back to the server 101 (the mode determination signal S2 is used to indicate that the 3D glasses 110 operate in a 2D or 3D mode), as in step S24. Finally, as shown in step S26, the server 101 determines a charging mode based on the operation mode indicated by the mode determination signal S2.

When the mode determination signal S2 indicates that the 3D glasses 110 are operating in the 3D mode, the server 101 performs charging at a first rate; when the mode determination signal S2 indicates that the 3D glasses 110 are operating in the 2D mode, the server 101 is in a second state. The rate is billed, where the first rate is different from the second rate. In the present embodiment, the first rate is greater than the second rate, but is not limited thereto. It should be noted that the charging mode may also be directly determined by the 3D glasses 110 without returning to the server 101. The above rate charging may also be directly performed in the 3D glasses 110.

Fig. 3 is a judgment mechanism shown in step S22 of Fig. 1. As shown in step S30, after the 3D glasses 110 start to judge, the 3D glasses 110 are judged to operate in the 2D mode or the 3D mode via the detector 118 in the 3D glasses 110 (step S32). If it is determined in step S32 that the 3D glasses 110 are operating in the 2D mode, the server 101 proceeds to step S36 to perform charging at the second rate. If it is determined in step S32 that the 3D glasses 110 are operating in the 3D mode, as shown in step S34, the timer 126 accumulates whether the time during which the 3D glasses 110 operate in the 3D mode exceeds a predetermined time. If the predetermined time is exceeded, the detector 118 generates the mode determination signal S2 in which the 3D glasses 110 operate in the 3D mode, and the server 101 performs the charging at the first rate, as shown in step S38. If the time accumulation of the 3D glasses 110 operating in the 3D mode does not exceed the predetermined time, the detector 118 generates the mode determination signal S2 in which the 3D glasses 110 operate in the 2D mode, and the server 101 performs the charging at the second rate, as in step S36. Shown. The first rate is different from the second rate, the first rate is applicable to the 3D mode, and the second rate is applicable to the 2D mode. It should be noted that the above-mentioned cumulative time action can also be performed by the server 101.

Fig. 4 is another judgment mechanism shown in step S22 of Fig. 2. Fig. 4 is similar to Fig. 3, and the difference is that the judgment mechanism of Fig. 4 is omitted after judging that the 3D glasses 110 operate in the 3D mode. In step S34 in Fig. 3, the server 101 directly charges at the first rate. For other steps, please refer to the description in Figure 3, and details are not described here.

Fig. 5 is a judgment mechanism of the step S32 shown in Fig. 3 and Fig. 4. As shown in step S50, the theater 101 transmits a control signal S1 by the server 101 through some wireless technology (Digital Light Processing (DLP), infrared (IR) or Bluetooth) when playing a 3D movie. The control signal S1 includes a left shutter drive signal and a right shutter drive signal, and the left shutter drive signal and the right shutter drive signal are switched according to a predetermined frequency (transition state). For example, the left shutter drive signal and the right shutter drive signal are respectively used to synchronize with the left shutter 114 and the right shutter 116 on the 3D glasses 110, and the switches of the left shutter 114 and the right shutter 116 cause the left and right eyes of the 3D glasses 110 to switch. . As shown in step S52, after the server 101 transmits the control signal S1, the detector 118 of the 3D glasses 110 detects the control signal S1, and starts to determine the left and right eye switching actions of the 3D glasses 110, and generates a touch determination signal. The mode determination signal S2 is used to indicate that the 3D glasses 110 are operating in the 2D mode or the 3D mode. After the detector 118 determines the left and right eye switching actions of the 3D glasses 110, the server 101 determines the charging mode according to the mode determining signal S2 (ie, the foregoing charging at the first or second rate).

As shown in step S54, when the left shutter 114 and the right shutter 116 of the 3D glasses 110 are respectively based on the left shutter driving signal of the control signal S1 and the right shutter driving signal, the left eye of the user only sees the left side of the 3D movie. The picture, while the right eye only sees the right picture (ie, operates according to the control signal S1, left and right), causing the image to have a 3D effect. At this time, the mode determination signal S2 indicates that the 3D glasses 110 operate in the 3D mode, and the detector 118 transmits the mode determination signal S2 to the server 101, so that the server 101 charges at the first rate in the 3D mode, such as steps. S55 is shown. As shown in step S56, when the left and right shutters 114, 116 of the 3D glasses 110 are simultaneously switched according to the frequency of the control signal S1 (for example, when the left shutter drive signal is on, the left and right shutters 114, 116 are simultaneously turned on and on the right). When the shutter drive signal is turned on, the left and right shutters 114, 116 are closed at the same time, and vice versa. The left and right eyes of the user can only see the left view screen or the right view picture of the 3D movie, so that the image presents the original 2D effect. At this time, the mode determination signal S2 indicates that the 3D glasses 110 operate in the 2D mode, and the detector 118 transmits the determination mode section signal to the server 101, and the server 101 charges the second rate in the 2D mode, as in step S47. Shown. It should be noted that the mode mode signal may be first stored in the storage device 124 of the 3D glasses 110, and then transmitted back to the server 101 by the transmitter 120 of the 3D glasses 110 or directly by the detector 118. Embodiments of the present invention enable a person who wants to watch 2D to watch the 2D version and charge the 2D version for the fee, while a person who wants to watch 3D watches the 3D and charges the 3D version for the fee, so that they can go to the movie together but People who want to see different versions separately do not have to watch separately. In addition, the film industry can also play the same movie that needs to occupy the two halls in different halls due to different modes, which can reduce the operating cost. Similarly, it can also be applied to playback devices outside the cinema.
