Screen projection program execution method of electronic device

The present invention relates to an electronic device, and more particularly to a method of executing a screen projection program that can project a screen of an electronic device onto another electronic device.

In recent years, various electronic devices have prevailed, and with the advancement of technology, display screens (or touch screens) and network connection functions have become the basic equipment of various electronic devices.

However, different electronic devices have different hardware specifications, some have strong hardware performance, which is good for processing data and graphics, but the screen is too small to be easily viewed (such as smart phones), and some have larger display screens. It is good for users to watch, but it can't handle programs that are too complicated (such as TV). Therefore, a screen projection program has been developed on the market that allows a user to execute a specific program on a powerful electronic device and transfer the screen of the electronic device to another display screen having a larger size. Displayed on the electronic device to facilitate user viewing.

As shown in the first figure, it is a system architecture diagram of the prior art. The user can install a screen projection software on the transmitting device 1, and the screen projection software can capture the screen of the transmitting device 1 and transmit it to a receiving device 2 through the network. Thereby, the receiving device 2 can transmit the received screen screen to the large-sized display 3 connected thereto for playing. Alternatively, if the receiving device 2 itself has a display screen, it can be played directly on the built-in display screen. Furthermore, as shown in the first figure, the transmitting end device 1 and the receiving end device 2 are connected to the same network mainly through a Wi-Fi hotspot 4 (Access Point, AP), thereby being used as the screen projection software. After being executed on the transmitting device 1, the receiving device 2 can be searched for and connected to the network.

As shown in the second figure, it is a prior art screen projection flowchart. When the user wants to transmit the screen of the transmitting device 1 to the receiving device 2, it is mainly necessary to download the installation file of the screen projection software to the transmitting device 1 (step S10). Next, double-click the downloaded installation file (step S11), so that after a series of "next" actions are clicked, the installation operation of the screen projection software is completed (step S12).

After the installation operation is completed, the user can activate the screen projection software on the transmitting end device 1 (step S13). If the transmitting device 1 is not connected to the network, the screen projection software can start searching for one or more Wi-Fi hotspots 4 that are available for connection in the vicinity, and the user selects one of them to connect (step S14). ). Then, after the user inputs the correct Wi-Fi password of the selected Wi-Fi hotspot 4, the network can be connected through the Wi-Fi hotspot 4 (step S15). After the network is connected, the screen projection software can search for one or more of the connected terminal devices 2 on the network, and the user selects one of them to connect (step S16). After the user inputs the correct access code of the receiving device 2, the screen projection software can establish a connection with the receiving device 2 (step S17), and further, the transmitting device 1 can pass the screen projection software. The screen is transmitted to the receiving device 2 (step S18).

As described above, in order to complete the above-described screen projection process, it takes a lot of complicated steps. Moreover, when the number of the Wi-Fi hotspots and the receiving end devices is plural, which Wi-Fi hotspot is to be connected to the network, and which receiving device is to be projected to the receiving device, It needs to be manually selected by the user; furthermore, if the selected Wi-Fi hotspot 4 and the receiving device 2 have a setting password, the user must manually input the correct password before connecting. As a result, not only will the user's inconvenience be caused, but the connection may fail due to user input errors.

Furthermore, the connection information of the receiving device 2, such as the IP Address and the access password, often changes due to various factors (for example, connecting another network causes the IP Address to change, or the user changes the access. The password, etc.), the Wi-Fi hotspot 4 may also have the possibility that the Wi-Fi password is changed. In this way, the user needs to re-select the object to be connected when reconnecting, and re-enter the changed password, which will cause considerable trouble for the user.

The main purpose of the present invention is to provide a method for executing a screen projection program of an electronic device, which can directly process the connection information of the object to be connected by the projection software, thereby eliminating the need for the user to manually select the connection object and manually input the connection. The trouble of the line information, and can avoid the problem of connection failure due to human error.

To achieve the above object, the present invention discloses a method for use between a transmitting device and a receiving device. When the two devices are to be connected, a file download request is first filed by the transmitting device. After receiving the file download request, the receiving device collects its own connection information and uses the connection information as the file name of the connected file. The content of the connection file includes a projection software. After the transmitting device downloads the connection file and executes it, the connection file extracts the connection information of the receiving device by the file name, and starts the projection software according to the connection information.

The effect that this creation can achieve according to the prior art is that the connection file is provided by the receiving device, and the receiving device provides the connection file to the transmitting device for downloading, and then collects various connection information (such as After the IP address and access password, etc., the collected connection information is used as the file name of the connection file.
