Description

Wireless screen projection method, device and system

Technical Field

The present application relates to the field of wireless screen projection technologies, and in particular, to a wireless screen projection method, device and system.

Background

The projection technology is developed from the slide age along with the progress of intelligent technology and optical technology, but in the process of using the projector, most of the devices such as computers are connected to the projector through wired connection, and the projector projects the content displayed on the computers to a large screen for display. Furthermore, a wireless screen projection technology is developed, high-definition display from a small screen to a large screen can be directly realized in a wireless mode through the technology, sharing of screen projection terminals by various signal sending end devices (mobile terminal devices such as a PC (personal computer), a notebook computer and a smart phone, and the like) can be realized, and the wireless screen projection technology is widely applied to scenes such as common households, business conferences, guests, multimedia classrooms in schools and the like.

In the process of implementing wireless screen projection, it is usually necessary to connect the signal sending end device and the screen projection terminal device to the same local area network. In addition, in a scene such as a business meeting, in consideration of information security and the like, it may be further required that, during the screen projection process, the identity of the signal sending end device is verified, and only devices belonging to a company or devices of employees of the company or persons granted authority by the company can use the screen projection terminal inside the company to implement wireless screen projection. Therefore, in such a scenario, it is generally necessary to install a screen projection application on the signal sending end device, and to log in the screen projection application through a pre-assigned account, password, and the like, and then, only a screen projection code of the screen projection terminal is input in the screen projection application, the screen can be projected wirelessly.

However, in a business meeting scenario, there is also often a need for a visitor to screen. For example, a supplier person of a certain company needs to go to the company to announce the product functions and the like supplied by the company, and in this case, it is necessary to perform wireless screen projection using a screen projection terminal of the company. However, the provider user may not have the screen projection authority, and the screen projection application may not be installed in advance in the device such as the computer of the provider user, and may not even be connected to the local area network inside the company. Therefore, wireless screen projection cannot be performed by directly inputting a screen projection code in a screen projection application.

Aiming at the requirement of screen projection of the visitor, a mode of realizing wireless screen projection by means of a hardware screen transmission device appears in the prior art, and the screen transmission device can be generally provided with interfaces such as a USB (universal serial bus) and can be connected to equipment such as a notebook computer; and the screen transmission equipment belongs to equipment matched with the screen projection terminal, so that the screen transmission equipment also belongs to equipment in a company. In the using process, the screen transmission device can be firstly inserted into the screen projection terminal to bind the information of the screen projection terminal device (including the IP address information of the screen projection terminal and the like), and the screen projection terminal can generate a wireless local area network (WiFi) hotspot to which the screen transmission device can be connected. After the binding operation is completed, the screen transmission equipment can be pulled out from the screen projection terminal and then inserted into signal sending end equipment such as a computer, and at the moment, the signal sending end equipment can realize wireless screen projection with the screen projection terminal through the screen transmission equipment.

By the mode, the signal sending end equipment of the visitor does not need to be connected to an intranet of a company, screen projection application does not need to be installed in advance, identity authentication does not need to be obtained in advance, and wireless screen projection of the screen projection terminal inside the company can be achieved by means of the hardware equipment.

However, in the above prior art scheme, before screen projection, screen transmission devices and screen projection terminals are required to be matched one by one, and even when multiple signal sending devices are required to project screens to the same screen projection terminal at the same time, more screen transmission devices are required to be matched with the screen projection terminals in advance. In some organizations such as large companies, the number of screen projection terminals may be very large, which means that a larger number of screen transmission devices need to be purchased to support the screen projection function of the visitor, and the hardware cost is high.

Therefore, how to reduce hardware cost on the basis of supporting screen projection of the visitor becomes a technical problem to be solved by the technical personnel in the field.

In addition, for the screen projection terminal device, because the screen transmission device does not need to be inserted for pairing with the screen transmission device, the screen projection terminal device does not need to reserve interfaces such as a USB (universal serial bus) for the screen transmission device, the hardware complexity and the cost of the screen projection terminal device can be reduced, and the ultrathin design of the screen projection terminal device can be realized.

The following describes in detail a specific technical solution provided in an embodiment of the present application.

Example one

First, the first embodiment provides a wireless screen projection system, and referring to fig. 1, the system may specifically include:

the screen projection system comprises screen projection terminal equipment 11, screen transmission equipment 12 and a server 13;

the screen projection terminal device 11 is configured to generate screen projection code information according to the network address information of the screen projection terminal device, and submit the screen projection code information and the network address information to the server 13;

the screen transmission device 12 is configured to release a screen projection application pre-installed in the screen transmission device 12 to the signal transmission device 14 for operation after being connected to the signal transmission device 14, and the screen projection application is configured to submit the input screen projection code information to the server 13 through the screen transmission device after receiving the screen projection code information;

the server 13 is configured to determine, according to the screen projection code information submitted by the screen transmission device 12, network address information of the corresponding screen projection terminal device 11 and return the network address information to the screen transmission device 12, so that wireless screen projection from the signal sending device 14 to the screen projection terminal device 11 is achieved through the screen transmission device 12.

The screen projection terminal device 11 may generally include a host and a display screen, and may also be in the form of a unitary device in practical applications. The host part is mainly used for realizing interaction of some information, including realization of networking functions and reception of specific data streams, and in the embodiment of the application, the host part also relates to functions of generation, submission and the like of screen projection codes. The display screen part is mainly used for displaying, including displaying screen projection codes, displaying subsequent specific screen projection contents and the like. The screen projection terminal device may be connected to a network in advance, for example, an internal local area network of an organization such as a company or an enterprise. After the screen-projecting terminal device 11 is started, a screen-projecting code may be generated according to the network address information. The screen-casting code can be generated according to an Internet Protocol (IP) address and/or Media Access Control (MAC) address information of the screen-casting terminal device, so that the uniqueness of the screen-casting code is ensured, and the screen-casting code can be used as an identity of the screen-casting terminal device. After the screen projection code is produced, the screen projection terminal equipment is provided with the display screen, so that the screen projection code can be displayed on the display screen, and a user who specifically needs to project the screen can view the screen projection code information of the screen projection terminal equipment through the display screen.

In addition, the screen projection terminal device may also submit the generated screen projection code information and the corresponding network address information to the server 13. Therefore, the corresponding relation information can be stored in the server 13, the server 13 can use the screen projection code information as the identity of the screen projection terminal device, and the screen projection code information submitted by the specific screen transmission device can be used for determining to which screen projection terminal device the specific signal transmission device needs to wirelessly project the screen.

The screen transmission device 12 may have an interface such as USB, and may be based on an embedded system such as linux, which may be used to support network connection and subsequent implementation of data transmission function. Specifically, in order to support a specific wireless screen projection function, the screen transmission device 12 may be connected to the same local area network as the screen projection terminal device 11. For example, both of them may be connected to an internal local area network of an organization such as a company and an enterprise in which the screen projection terminal device 11 is currently located, or a wireless local area network hotspot may be generated by the screen projection terminal device 11, and the screen transmission device 12 is connected to the hotspot of the screen projection terminal device 11, that is, the screen transmission device 12 and the screen projection terminal device 11 may be located in the same local area network.

In addition, a mobile storage product such as a usb disk may be further built in the screen transmission device 12, wherein the screen projection application may be pre-installed. The screen-casting application may be an application developed specifically for a visitor screen-casting scene, and may have different functions from a screen-casting application for employees within an organization. Specifically, after the screen projection device 12 is specifically connected to the signal transmission device 14 (e.g., plugged into a USB interface of the signal transmission device, etc.), the screen projection application may be released to be run in the signal transmission device 14. For example, after the screen transfer device 12 is inserted into the signal transmission device 14 through an interface such as USB, an icon of the screen transfer device 12 can be found in an interface such as "computer" of the signal transmission device 14, and by double-clicking the icon, the screen-casting application can be run in the signal transmission device 14 without local installation. After the screen projection application is operated, a user interface can be displayed, and through the application interface provided by the screen projection application, a user can input screen projection code information displayed in the display screen of the screen projection terminal device 11 into the screen projection application. Then, the screen projection application can send the screen projection code information to the screen transmission device 12 through a USB channel or the like, and the screen transmission device 12 can submit the screen projection code information to the server 13. Thus, the server 13 can determine that the current signal sending device needs to perform wireless screen projection with the screen projection terminal device corresponding to the screen projection code. Meanwhile, since the server 13 pre-stores the corresponding relationship between the screen-projecting code information and the network address information of the screen-projecting terminal device, and the network address information is needed in the process of realizing wireless screen projection by using the screen-transmitting device 12, the server 13 can return the network address information of the screen-projecting terminal device corresponding to the screen-projecting code information to the screen-transmitting device 12.

After receiving the network address information of the specific screen projection terminal device 11, the screen transmission device 12 can implement wireless screen projection from the signal transmission device 14 to the screen projection terminal device 11. Particularly, in the process of implementing the wireless screen projection, a signaling negotiation between the signal transmitting device 14 and the screen projection terminal device 11 may be involved. For this reason, the screen transmission device 12 may transmit the network address information of the screen projection terminal device 11 to the screen projection application running in the signal transmission device 14 through a channel such as a USB channel. Then, the signaling device 14 can implement signaling negotiation with the screen projection terminal 11 by means of the screen transmission device 12. After the signaling negotiation is completed, the screen-casting application can generate information flow of the information to be screen-cast in the signal sending device 14, and can also generate control commands according to the network address information and the like of the screen-casting terminal device 11, and transmit the control commands to the screen-transmitting device 12 through channels such as a USB and the like, and then transmit the control commands to the screen-casting terminal device 11 through protocols such as a websocket and a udp, and the screen-casting terminal device 11 displays specific data, so that the screen-casting process can be completed.

In a specific implementation, after completing a screen projection process (for example, a user presses a button on the screen projection device to end screen projection, etc.), the screen projection device 12 may clear information about the screen projection terminal device 11, that is, the information about the screen projection terminal device 11 is not bound to the screen projection device 12. In this way, in the new screen projection requirement, the screen transmission device 12 may further obtain information of other screen projection terminal devices 11 from the server, and implement wireless screen projection between the signal sending device 14 and the other screen projection terminal devices 11.

It should be noted that, in the embodiment of the present application, the specific signal transmission device 14 may have various specific forms, for example, may be a PC (personal computer) device, or may be a notebook computer device, and the like. In the process of implementing the specific wireless screen projection, the specific signal sending device 14 can implement the wireless screen projection to the screen projection terminal device 11 through the screen transmission device 12 without networking and installing the related screen projection application in advance, so that the wireless screen projection in the visitor scene can be supported.

In addition, in specific implementation, the screen transmission device may be connected to the signal sending device in a data line port manner. In order to meet the requirement that multiple signal sending devices share the same screen projection terminal device in some scenes, the screen transmission device may further include multiple data line ports for connecting to multiple different signal sending devices, so as to share the screen projection terminal device among the multiple different signal sending devices. In terms of software, the screen transmission device can store the identification information of each port, so that after being connected to a plurality of different signal sending devices, the identification information of different data line ports connected with the plurality of different signal sending devices can be obtained, interaction with the plurality of different signal sending devices can be performed according to the identification information, and wireless screen projection sharing is realized between the plurality of signal sending devices and the screen projection terminal device.

Furthermore, in practical applications, there may be a need to perform screen projection to multiple screen projection terminals from the same signal transmission device, for example, in some relatively large conference rooms, multiple screen projection terminals may need to be arranged, so that participants in different directions can view specific screen projection contents from different screen projection terminals. The scheme provided by the embodiment of the application can also meet the requirement. Specifically, after the screen projection terminals respectively generate respective screen projection codes and display the screen projection codes on the specific screen projection terminals, the screen projection terminals can respectively submit the respective screen projection codes, IP addresses and other information to the server; and an input frame for inputting a plurality of screen projection codes can be provided in the interface of the screen projection application provided by the screen projection equipment, so that the screen projection equipment can input the screen projection codes of a plurality of screen projection terminals in the signal sending equipment after being inserted into the signal sending equipment, and the screen projection codes are submitted to the server side through the screen projection equipment respectively. The server side can return network address information such as IP of a plurality of screen projection terminals corresponding to each screen projection code, the signal sending equipment can perform network negotiation with the plurality of screen projection terminals respectively, and then the signal sending equipment can project screens to the plurality of screen projection terminals through the screen transmission equipment.

In a word, according to the embodiment of the application, the screen projection terminal equipment and the screen transmission equipment can be managed through the server, and after the screen codes are projected on products, the screen projection codes and the network address information of the screen projection terminal equipment can be submitted to the server for storage. Therefore, the server can use the screen projection code information as the identity of the screen projection terminal equipment. After the screen transmission equipment is connected to the signal sending equipment, screen projection codes of specific screen projection terminal equipment can be input into the signal sending equipment, the screen projection codes are submitted to the server by the screen transmission equipment, the server can know which screen projection terminal equipment needs to be subjected to screen projection specifically, and network address information of the screen projection terminal equipment is returned to the screen transmission equipment. Therefore, after the screen transmission device acquires the network address information of the specific screen projection terminal device, the wireless screen transmission from the accessed signal sending device to the screen projection terminal device can be realized. Through the mode, the specific screen transmission equipment can acquire the network address information of the screen projection terminal equipment which needs to project the screen from the server, and therefore before the screen is projected specifically, the screen transmission equipment does not need to be matched with the screen projection terminal equipment one by one, and the same screen transmission equipment can be matched with a plurality of different screen projection terminal equipment for use, so that the wireless screen projection under scenes such as visitors can be realized, and the hardware cost can be saved.
