Description
Technical Field
The present invention relates to a display system, and more particularly to a wireless conferencing system including a self-powered data transmitter adapted to be connected to a computer device for at least wirelessly transmitting data to a display device without consuming power from the computer device.
Background
As the demand for communication has developed, the effectiveness of data transfer between different computer devices has increased to improve user ease of use, particularly during seminars, conferences or presentation meetings. Traditionally, the computer device is connected for data transmission via a cable communication link. For example, during a meeting or a presentation, a host computer such as a notebook computer, smart phone or tablet computer is connected to a display device such as a monitor, television or projector through an HDMI cable so that information data, video data, audio data, etc. can be efficiently transmitted from the host computer to the display screen of the display device. However, such wire connections are configured with several disadvantages. For example, the connection distance between the host and the display device is limited by the length of the HDMI cable. A host is connected to the display device by only one cable. When a plurality of hosts are connected, a plurality of cables must be used, and the wiring arrangement becomes complicated. Furthermore, it requires additional software and/or hardware to share files or data between the computers.
An improved data transmission system is a wireless connection between the computers, or between the computers and the display device, over a wireless network. For example, the host may be wirelessly connected to a "WiFi" network to transmit the data to different computers and/or display devices via the "WiFi" network. However, all computers are susceptible to wireless security risks. Especially when the computer is allowed to share files over the "WiFi" network, even a personal network, any software infected by a computer virus can easily be implanted into the computer, and the computer is also vulnerable to hacking.
Another wireless connection is established by connecting a wireless transmitter to the computer and a wireless receiver at the display device, for example US patent numbers US7949609, US8493992, US9160975, US9578336, US10585814, US10693924, and US20100066806, wherein the data can be wirelessly transmitted from the computer to the display device when the wireless transmitter is wirelessly connected to the wireless receiver. In one example, the wireless transmitter interfaces with a USB interface and the wireless receiver interfaces with an HDMI interface. As is well known, the USB interface is an interface for computer connection, and is not a data transmission interface. In other words, corresponding software must be installed on the computer to enable data transmission via the USB interface. Specifically, the software is encoding software for encoding video data, audio data, and the like after being transmitted to the display device. Therefore, the host must install the encoded software prior to the meeting. It is not safe to install any unknown software into the computer. In addition, the wireless transmitter is not a self-powered device, and therefore the wireless transmitter needs to draw power from the computer, resulting in reduced battery life of the computer. One annoying situation is that the notebook computer has lost power in the middle of the presentation. Furthermore, there is no information telling the presenter how much power the wireless transmitter plugged into the host will consume.
In addition, the wireless receiver is only a receiving end, and only receives data from the wireless transmitter. In other words, the control operation is a one-way operation, wherein the display device does not provide any control capability. Another disadvantage of the wireless transmitter and the wireless receiver is compatibility issues. Such connections may not be compatible with different operating systems, such as the "Window," "Android," or "IOS" operating systems.

According to a preferred embodiment, wherein the communication connection between the data sender 10 and the data receiver 20 is not unidirectional. In other words, the data transmitter 10 not only transmits data to the data receiver 20, but also receives data from the data receiver 20, as shown in fig. 8. In particular, when the computer device 100 or the display device 200 is a touch screen control device, the data receiver 20 is configured to transmit a control signal to the data transmitter 10. The control signal is generated and transmitted from the data receiver 20 to the data transmitter 10 by touching the screen of the computer device 100 or the display device 200 to control the computer device 100. For example, by dragging a finger across the screen of the display device 200 to generate the control signal "turn to next page", the data transmitter 10 receives the control signal to control the computer device 100 to generate data of "next page" to be displayed on the display device 200.
In order to efficiently transmit the control signal from the data receiver 20 to the data transmitter 10, the data transmitter 10 further includes a wireless controller 16 wirelessly connected to the data receiver 20 to receive the control signal therefrom. It should be noted that the wireless controller 16 is not a wireless connection device. The wireless controller 16 is only used to receive the control signal from the data receiver 20.

In other words, the computer device 100 requires two separate ports, for example an HDMI port and a USB port, to connect the computer interface 13 and the wireless controller 16, respectively. Alternatively, the wireless controller 16A may be built into the housing of the data transmitter 10 to form a single unit, such that the computer device 100 requires only one port, such as a USB port, for connecting to the computer interface 13.
According to the preferred embodiment, when two or more of the data transmitters 10 are used, the data transmitters 10 can be used as a laser pointer 10A and a remote controller 10B.
In one configuration of a laser pointer 10A, as shown in FIG. 9, two data transmitters 10 are coupled to each other to the data receiver 20. One of the data transmitters 10 is connected to the computer device 100 to transmit the data to the data receiver 20. Another one of the data transmitters 10A, as the laser pointer 10A, is wirelessly connected to the wireless controller 16(16A) through the data receiver 20. When the laser pointer 10A is set to transmit an indication signal as the control signal to the data receiver 20, the data receiver 20 transmits the indication signal to the data transmitter 10 via the wireless controller 16(16A) to control the computer device 100 and for establishing an indication on the display device. It is noted that the wireless controller 16(16A) may be a standalone device or a built-in device. As shown in fig. 9, the wireless controller 16 is the stand-alone device.
In one configuration of a remote controller 10B, as shown in fig. 10, two data transmitters 10 are coupled to the data receiver 20 with each other. One of the data transmitters 10 is connected to the computer device 100 to transmit the data to the data receiver 20. Another one of the data transmitters 10B is connected wirelessly as the remote controller 10B to the data transmitter 10 through the wireless controller 16 (16A). When the remote controller 10B is set to transmit a remote control signal to the data transmitter 10, the remote controller 10B is set to remotely control the computer apparatus 100. As shown in fig. 10, the wireless controller 16 is the stand-alone device.
According to a preferred embodiment, a plurality of said data receivers 20 can be coupled to each other to a plurality of data transmitters 10 with a wireless connection. In one configuration, the data receiver 20 is wirelessly connected to the data transmitter 10 via the closed private network to form a display group, wherein when at least one of the data receivers 20 is connected to at least one of the display devices 200, respectively, the data transmitter 10 simultaneously transmits the data to the data receiver 20 so that the data will be simultaneously displayed on the display devices 200.
In another arrangement, as shown in figure 7, one of the data receivers 20 is wirelessly linked to the data sender 10 via the closed private network and is arranged to be connected to one of the data receivers 20 via a wireless network different from the closed private network. In other words, the data receivers 20 are connected to each other through the wireless network. Only one of the data receivers 20 is wirelessly connected to the data transmitter 10 through the closed private network. Thus, for example, the data receiver 20 acts as a primary data receiver when connected to the data transmitter 10 via the closed private network, and the other data receivers 20 act as secondary data receivers when connected to the other data receivers 20 via the wireless network.
During the meeting, data will be shared by the different computer devices 100. Thus, the data receiver 20 is adapted to be connected to a computer device 100 for sharing and/or displaying the data transmitted from the data transmitter 10. As shown in fig. 12, wherein the data receiver 20 preferably further comprises a receiver encoding unit 25 and a USB interface 26, wherein the receiver encoding unit 25 encodes the data from the built-in decoding unit 24, wherein the USB interface 26 of the data receiver 20 is configured to connect to an output computer device 100A for transmitting data from the receiver encoding unit 25 to the output computer device 100A. Preferably, the USB interface 26 of the data receiver 20 is a UVC/UAC USB for connecting to the output computer device. This configuration is particularly suitable for live and conference platforms.
Thus, the wireless conferencing system of the present invention can be integrated with different computer devices 100 having different operating systems, such as personal computers, notebook computers, tablet computers, mobile phones, and the like. For the personal computer, notebook computer, and tablet computer, the data transmitter 10 may be directly connected to these computer devices 100. For the mobile phone or tablet computer, the data receiver 20 may be wirelessly connected to the mobile phone to transfer data therefrom.
Therefore, there are two main streams for the operating system of the existing mobile phone, namely "IOS" and "Android". According to the preferred embodiment, wherein the data receiver 20 is configured to have an AP (wireless access point) mode of operation and a P2P (point-to-point) mode of operation, for ensuring a real-time data transmission between the data transmitter 10 and the data receiver 20.
