Description

Wireless data sharing system

The present invention describes a wireless data sharing system, and more particularly to a wireless data sharing system for use in conference reporting.

With the rapid development of Internet technology, a variety of single-point or multi-point network systems have become popular in everyday life applications. For example, the data on the host side of the user can be transmitted to another host through a point-to-point transmission channel. The user host can also receive the data uploaded by the server and transfer the data to another host through a relay node or a network node. Also, the user must pre-set all wireless network parameters before the network connection is established. For example, the user must set the parameters of the Dynamic Host Configuration Protocol, the parameters of the destination Internet Protocol Address, the Gateway address, and the user data packet protocol. (User Datagram Protocol) parameters, in order to make a single point or multi-point network to establish a connection. Because wireless networks can be used to transmit data and share data, they are often used in conference reports to enable reporters who participate in conference reports to present report data.

In general, when a wireless network is used in a conference report, each reporter can control the corresponding computer for data reporting. The chairman of the meeting controls the length of each speaker's statement. For example, when the reporter has finished speaking, the chairman will use the bell to remind the reporter. The chairperson can also use the microphone to inform the next reporter to start preparing the report.

However, in traditional conference reports, since there is no systematic way to control or inform the reporter (or the reporter's computer) to prepare the report or interrupt the report, the chairman can only use the microphone or ringing method. The reporting time is controlled by the mode of traditional sound notification, so this method of notification or control is inefficient. Moreover, since all wireless network parameters are input to the computer one by one to establish a network connection, in the traditional conference report, the pre-work of wireless transmission of data will waste a lot of time and reduce convenience.

An embodiment of the present invention provides a wireless data sharing system, including a display device, a wireless video sharing device, a plurality of computer terminals, a slave control device, and a primary control device. The display device is configured to display video and audio data, and the wireless video and audio sharing device is connected to the display device for transmitting the audio and video data to the display device. A plurality of computer terminals are connected to the wireless video sharing device for transmitting audio and video data to the wireless video sharing device. Each slave control device is connected to a corresponding first computer terminal of the computer terminals for controlling the corresponding first computer terminal. The main control device is connected to the second computer terminal of the computer terminals for controlling the second computer terminal and the slave control devices. The slave control device may be plural. When the primary control device controls one of the slave control devices, the primary control device controls the first computer terminal connected to the slave control device to transmit the audio and video data to the wireless video/video sharer. .

Another embodiment of the present invention provides a wireless data sharing system including a display device, a wireless video sharing device, a slave control device, and a primary control device. The display device is configured to display audio and video data, and the wireless video sharing device is connected to the display device for transmitting the video and audio data to the display device. The slave control device is connected to the wireless video sharing device, and when the slave control devices are plural, each slave control device is connected to the corresponding first computer terminal for controlling the corresponding first computer terminal. The main control device is connected to the wireless video sharing device and the second computer terminal for controlling the second computer terminal and the slave control devices. When the primary control device controls the slave control devices, the primary control device controls the first computer terminal connected to the slave control device to cause the first computer terminal to transmit the video and audio data to the wireless video/video sharer through the slave control device.

FIG. 1 is a block diagram of a wireless data sharing system 100. The wireless data sharing system 100 includes a display device 10, a wireless video sharing device 11, a plurality of computer terminals 121 to 12N, a plurality of slave control devices 132 to 13N, and a master control device 131. N is a positive integer greater than or equal to 2. The display device 10 is for displaying video and audio materials, and the display device 10 can be a projector device, a display device or any form of video player. The wireless video sharing device 11 can be any form of wireless multimedia sharing device. For example, the wireless video sharing device 11 can be a sharer that establishes a wireless connection by using a dual channel mode to share data. The wireless video sharing device 11 can also be a wireless briefing sharer with a network gateway function ( Wireless Presentation Gateway) with the ability to access and transfer data. In the wireless data sharing system 100, the wireless video sharing device 11 is connected to the display device 10 for transmitting video and audio data to the display device 10. The computer terminals 121 to 12N are connected to the wireless video/video sharing unit 11 for transmitting the video and audio data to the wireless video/video sharer 11. In the wireless data sharing system 100, the computer terminals 121 to 12N may be a plurality of notebook computers, personal computers, tablet computers, handheld smart devices or workstations. The slave control devices 132 to 13N can be controlled by the user (reporter control of the conference report). The slave control devices (132 to 13N) are connected to the corresponding first computer terminals (122 to 12N) for controlling the corresponding first computer terminal. For example, the slave control device 132 is coupled to the computer terminal 122 such that the user can operate the slave control device 132 to control the computer terminal 122. The main control device 131 is connected to the second computer terminal (121) for controlling the second computer terminal and the slave control devices 132 to 13N. For example, the main control device 131 is connected to the computer terminal 121 so that the user can operate the main control device 131 to control the computer terminal 121. Further, the main control device 131 can also control the slave control devices 132 to 13N via the wireless video sharing device 11. In the wireless data sharing system 100, the slave control devices 132 to 13N and the primary control device 131 may be plug-and-play portable devices. The main control device 131 and the slave control devices 132 to 13N can be connected to the corresponding computer terminals (121 to 12N) through any type of connection, for example, through a universal serial bus (Universal Serial Bus), a micro universal serial bus ( A Micro-universal Serial Bus or a Mini-Universal Serial Bus is connected to the computer terminal 121. In the wireless data sharing system 100, when the primary control device 131 controls one of the slave control devices 132 to 13N, the primary control device 131 will obtain control authority to cause the computer terminal connected to the controlled slave control device The audio and video data on the video is transmitted to the wireless video sharing device 11. Subsequently, the wireless video sharing device 11 receives the audio and video material and transmits the video and audio material to the display device 10. The architecture of the primary control device 131 and the slave control devices 132 to 13N will be described in detail below, and the transmission mode of the video material will be explained.

2 is a front view of the main control device 131 of the wireless data sharing system 100. Figure 3 is a front elevational view of one of the slave control devices 132 through 13N of the wireless data sharing system 100. For the sake of description simplification, the slave control devices 132 to 13N have similar structures, while the third diagram describes a representative structure thereof, and the wireless data sharing system 100 of FIGS. 2 and 3 considers the main control device 131. And four slave control devices 132 to 135 (N is 5 here). However, as described above, the wireless data sharing system 100 may have more than four slave control devices, and the number of slave control devices is not limited by the second and third figures. In Fig. 2, the main control device 131 includes a moderator key MK and four control keys CKA to CKD. Since the main control device 131 is connected to the computer terminal 121 via the connection port 15, the main control device 131 can control the computer terminal device 121 to transmit the video and audio data (the audio and video data of the user 1) by using the chairman button MK, so that the video and audio data can be presented. On the display device 10. The main control device 131 can also control the computer terminal 121 to suspend the transmission of the video and audio data by using the chairman button MK, so that the video and audio material is in the pause state on the display device 10. The four control keys CKA, CKB, CKC, and CKD are used to control the respective slave control devices 132 to 135, respectively. Here, the function of the control keys CKA to CKD is to enable the transmission of video and audio data to present the report data, or to disable the transmission of the video data to pause or even terminate the presentation of the report data. For example, in the conference report, the chairman (user 1) can control the slave control device 132 using the control button CKA. When the chairman presses the control button CKA, the main control device 131 generates a control signal and transmits the control signal to the slave control device 132 through the wireless video/video sharer 11. Subsequently, the slave control device 132 will be controlled to cause the video material (the data of the user 2) to start transmission (final transmission to the display device 10). However, the chairman can switch control buttons at any time. For example, after the user 2 completes the report of the video material, the chairman can press the control button CKB to control the slave control device 133 to start the transmission of the video material (the data of the user 3) (final transmission to the display device 10). ). In other words, after the chairman presses the control button CKB, the user 3 can start the reporting process of the video material.

In Fig. 3, the slave control device includes a port 16 for connection to a corresponding computer terminal. The slave control device further includes a quick key HK for controlling the corresponding computer terminal to transmit video and audio data. In the present invention, the wireless data sharing system 100 introduces two control modes. In the first control mode, the primary control device 131 controls the slave control device (e.g., the slave control device 132). When the slave control device is in the controlled state, the shortcut key HK is used to provide a computer terminal (e.g., the computer terminal 122) connected to the slave control device to perform a transmission stop function of the video material. In the second control mode, primary control device 131 releases control of the slave control device (e.g., slave control device 132). Here, the shortcut key HK of the slave control device is used to provide a computer terminal (such as the computer terminal 122) connected to the slave control device to perform a transmission and playback function or a transmission termination function of the audio and video material. In short, when the slave control device is being controlled by the master control device 131, the user of the slave control device can only perform the transmission stop function of the video material using the quick key HK. When the main control device 131 releases the control right, the user of the slave control device can perform the transmission play function or the transmission termination function of the video material using the quick key HK. Moreover, when the main control device 131 is disconnected, the wireless data sharing system 100 also enters the second control mode. With the above operation mode, since the chairman can control the designated slave control device by the main control device 131 to transfer the corresponding video and audio data from the computer terminal to the display device 10, the efficiency of the conference report can be improved. In particular, in FIG. 2, the chairman key MK of the main control device 131 can be regarded as a button for controlling the computer terminal 121 itself, and the control button CKA of the main control device 131 can be a button for controlling the slave control device 132. In other words, when the slave control device 132 is controlled by the master control device 131, the control key CKA of the master control device 131 has the control right corresponding to the quick key HK of the slave control device 132. And so on, when the other slave control devices are also controlled by the main control device 131, the control keys CKB to CKD of the main control device 131 are also the control rights of the quick keys HK corresponding to the different slave control devices. Therefore, the main control device 131 can easily operate the function of the shortcut key HK corresponding to the slave control device through the control keys CKA to CKD, thereby improving the efficiency of the conference report.

In the wireless data sharing system 100, all wireless network setting parameters may be user-defined parameters or predetermined parameters built into the system. When these wireless network setting parameters are changed, the updated wireless network setting parameters will be automatically stored in the primary control device 131 and the secondary control devices 132 to 13N. Therefore, when the main control device 131 and the slave control devices 132 to 13N are connected to the corresponding computer terminal, the connection between the display device 10, the wireless video sharing device 11, and the computer terminals 121 to 12N will be automatically The ground is built and therefore has high operational efficiency. In the wireless data sharing system 100, the main control device 131 and the slave control devices 132 to 13N can establish a connection with the wireless video/player 11 by using the corresponding computer terminal through the architecture as shown in FIG. However, the wiring architecture of the present invention is not limited to FIG. For example, the main control device 131 and the slave control devices 132 to 13N themselves can have wireless communication capabilities, so that the wireless video sharing device 11 can be directly connected to the wireless video sharing device. Other embodiments of the invention will be described in detail later.

In the wireless data sharing system 100, when the primary control device 131 is to control the slave control device 132, the primary control device 131 can generate a control signal, and the control signal is transmitted to the wireless video/player 11 through the computer terminal 121. Subsequently, the wireless video sharing device 11 transmits the control signal to the computer terminal 122 corresponding to the slave control device 132. Since the slave control device 132 and the computer terminal 122 are connected to each other, the master control device 131 can acquire the control right of the slave controller 132.

Figure 4 is a block diagram of a wireless data sharing system 200. The wireless data sharing system 200 architecture is similar to the architecture of the wireless data sharing system 100, with the difference that each of the primary control device 131 and the slave control devices 132 to 13N can directly establish a wireless connection to the wireless video sharing device 11. . In the wireless data sharing system 200, the main control device 131 and the slave control devices (132~13N) do not use wireless communication modules (such as wireless fidelity communication modules) built in the corresponding computer terminals to access the wireless video and audio. The sharer 11 establishes a wireless connection. Instead, the primary control device 131 and the slave control devices (132~13N) use the built-in wireless communication module to directly establish a wireless connection to the wireless video/video sharer 11. For example, as shown in Figure 5. Figure 5 is a front elevational view of the primary control device 131 of the wireless data sharing system 200. The main control device 131 of the wireless data sharing system 200 is similar to the main control device of the wireless data sharing system 100 in FIG. 2, except that the main control device 13 of the wireless data sharing system 200 internally includes a wireless transceiver TS. . Similarly, as shown in Figure 6. Figure 6 is a front elevational view of the slave control device of the wireless data sharing system 200. The slave control device of the wireless data sharing system 200 is similar to the slave control device of the wireless data sharing system 100 of FIG. 3, except that the housing of the slave control device of the wireless data sharing system 200 includes a wireless transceiver TS. It is to be noted that the wireless transceiver TS can be a device for transmitting and receiving wireless signals, such as a wireless fidelity (Wi-Fi) transceiver or a Bluetooth transceiver. The wireless transceiver TS can be a wireless transceiver built into the primary control device 131 and the slave control devices 132 to 13N, or can be a non-embedded system chip type wireless transceiver. In other words, the computer terminal 121 establishes a connection to the wireless video/player 11 through the wireless transceiver TS in the corresponding primary control device 131. The computer terminal 122 establishes a connection to the wireless video/player 11 via the wireless transceiver TS in the corresponding slave control unit 132. By analogy, the computer terminal 12N establishes a connection to the wireless video/player 11 through the wireless transceiver TS in the corresponding slave control device 13N. In other words, in FIG. 4, since the main control device 131 and the slave control devices 132 to 13N can establish a connection to the wireless video sharing device 11 by using the built-in wireless transceiver TS, the main control device 131 and the slave control In the corresponding computer terminal to which the devices 132 to 13N are connected, a wireless network program must be installed to drive the wireless transceiver TS. The installation and characteristics of the wireless network program of the primary control device 131 and the slave control devices 132 to 13N will be described later.

In order to simplify the description, the installation characteristics of the wireless network program of the main control device 131 will be described below, and the installation characteristics of the wireless network program in the slave control devices 132 to 13N are similar to those of the main control device 131, so it will be described here. Omitted. In the initial state, the computer terminal 121 does not register or install a wireless network program. After the main control device 131 is connected to the computer terminal 121, the user can manually install the installation file of the wireless network program stored in the main control device 131. Subsequently, the wireless network program is installed to the computer terminal 121. After the program installation is completed, the computer terminal 121 will drive the wireless transceiver TS in the main control unit 131 to establish a wireless connection. After the wireless connection between the main control device 131 and the wireless video sharing device 11 is completed, the audio and video data in the computer terminal 121 can be transmitted to the wireless video sharing device 11 through the main control device 131. Moreover, after the main control device 131 and the slave control devices 132 to 13N both establish a connection to the wireless video sharing device 11, the main control device 131 can control the designated slave control device to connect the computer terminal to the designated slave control device. The audio and video data on the machine is transmitted to the wireless video sharing device 11. Since the wireless network program needs to be installed before the wireless connection is established, the wireless data sharing system 200 can be regarded as a non-zero Footprint. More precisely, after the wireless network program is installed on the computer terminal 121, the wireless network program can enable the wireless network chip or the wireless transceiver TS in the main control device 131 and program it. The command and network setting parameters are imported and drive the wireless network chip or the wireless transceiver TS to enable data transmission. For example, the wireless network program drives the main control device 131 according to the data packet format, the User Datagram Protocol data length, the Transmission Control Protocol data length, the Maximum Transmission Unit, and the like. The wireless network chip or the wireless transceiver TS. However, the present invention is also not limited to the use of wireless network program installation to enable the primary control device 131 and the slave control devices 132 to 13N to have data transmission capabilities. For example, in other embodiments, the present invention may utilize appropriate application programs, login set commands, or any networked drive software to enable primary control device 131 and slave control devices 132 through 13N to have data transfer capabilities. .

Figure 7 is a schematic diagram of the desktop DT of the computer terminal of the wireless data sharing system 200. More precisely, Figure 7 is a schematic diagram of the screen displayed on the desktop DT after the wireless terminal program is installed on the computer terminal. In Figure 7, the desktop DT displayed on the computer terminal contains two wireless network connection status (bottom right corner of Figure 7). The wireless network connection state WSD indicates the connection state of the main control device (or the slave control device). The wireless network connection status WSC indicates the state of the wireless network of the computer terminal itself connected to the main control device (or the slave control device). As shown in FIG. 7, since the wireless network connection state WSD and the wireless network connection state WSC operate independently, the wireless network operation of the main control device (or the slave control device) and the computer terminal itself are performed. Wireless network operation can be done independently. For example, after the main control device (or the slave control device) is connected to the wireless video/audio sharer 11, the user can use the computer's own wireless network module to retrieve data from the network. There will be no bandwidth interference between them. Therefore, since the wireless data sharing system 200 has the capability of two-channel wireless transmission, the convenience and flexibility of operation can be improved.

Moreover, in the wireless data sharing system 200, since the main control device 131 and the slave control devices 132 to 13N control the transmission stop function, the transmission play function, or the transmission termination function of the video data using the chairman key MK or the quick key HK, the method is similar to wireless. Data sharing system 100. Therefore, the description will be omitted here.

In the wireless data sharing system 200, when the primary control device 131 wants to control the slave control device 132, the primary control device 131 can generate a control signal and transmit the control signal to the wireless video/video sharer 11 through the wireless transceiver TS. Subsequently, the wireless video sharing device 11 transmits the control signal to the slave control device 132. Therefore, after the wireless transceiver TS of the slave control device 132 receives the control signal, the primary control device 131 can take control of the slave control device 132.

The difference between the control modes of the wireless data sharing system 100 and the wireless data sharing system 200 of the present invention is that, in the wireless data sharing system 100, the control signals generated by the primary control device 131 are sent to the wireless video and audio via the computer terminal 121. The sharer 11, the wireless video sharing device 11 transmits the control signal to the computer terminal (122) corresponding to the slave control device (e.g., 132). In other words, in the case of the control signal, the transmission and reception of the control signal are performed by the computer terminal. In the wireless data sharing system 200, the control signal generated by the main control device 131 can be directly transmitted to the wireless video sharing device 11 via the built-in wireless transceiver TS, and the wireless video sharing device 11 transmits the control signal to the slave control. The device (e.g., 132), and the wireless transceiver TS built into the slave control device will receive the control signal. In other words, in the case of the control signal, the transmission and reception of the control signal can be performed by the main control device 131 and the wireless transceiver TS built in the slave control device.

Although the wireless data sharing system 100 and the wireless data sharing system 200 provide different connection paths for displaying video and audio materials, the wireless data sharing system of the present invention is not limited to the aforementioned connection path. For example, a wireless data sharing system can use a router. When the wireless data sharing system uses the router, the computer terminals 121 to 12N in FIG. 1 will be connected to the wireless video sharing device 11 through the router, and the main control device 131 and the slave control devices 132 to 13N in FIG. 4 will It will be connected to the wireless video sharing device 11 through the router.

In summary, the present invention discloses a wireless data sharing system. The wireless data sharing system can be applied to conference reports to improve the efficiency of the reporting process. The wireless data sharing system can perform the operation of the report using the primary control device and the plurality of slave control devices. Also, the primary control device can control the designated slave control device or release control of the designated slave control device. Since the main control device of the wireless data sharing system and the plurality of slave control devices control the data transmission by means of button operation, the efficiency of the conference report can be improved. The above are only the preferred embodiments of the present invention, and all changes and modifications made to the scope of the present invention should be within the scope of the present invention.
