Embodiment 1

[0073] like image 3 As shown, a screen projection method according to the first embodiment of the present invention is proposed, and the method includes the following steps:

[0074] S11. The sender starts the SoftAP mode.

[0075] In this embodiment of the present invention, the SoftAP mode may be automatically activated by the sender when a preset condition is met, or the SoftAP mode may be manually activated by the user, such as manually turning on the SoftAP mode switch.

[0076] Optionally, when the sending end receives the projection instruction for sending data, it automatically starts the SoftAP mode. For example, the terminal starts the screen projection application and displays the button or pattern for sending and receiving data. When the user clicks the button or pattern for sending data, the terminal receives the projection instruction for sending data, and immediately starts automatically as the sender. SoftAP mode.

[0077] In some embodiments, the projectio...

Embodiment 2

[0095] like Figure 4 As shown, a screen projection method according to the second embodiment of the present invention is proposed. The method is applied to the transmitting end and includes the following steps:

[0096] S21. The sender starts the SoftAP mode.

[0097] In this embodiment of the present invention, the SoftAP mode may be automatically activated by the sender when a preset condition is met, or the SoftAP mode may be manually activated by the user, such as manually turning on the SoftAP mode switch.

[0098] Optionally, when the sending end receives the projection instruction for sending data, it automatically starts the SoftAP mode. For example, the terminal starts the screen projection application and displays the button or pattern for sending and receiving data. When the user clicks the button or pattern for sending data, the terminal receives the projection instruction for sending data, and immediately starts automatically as the sender. SoftAP mode.

Embodiment 3

[0110] like Figure 5 As shown, a screen projection method according to a third embodiment of the present invention is proposed, and the method includes the following steps:

[0111] S31. The sender starts the SoftAP mode.

[0112] This step S31 is the same as the step S11 in the first embodiment, and will not be repeated here.

[0113] S32. The transmitting end selects a channel with less interference at the current location.

[0114] In this step S31, after starting the SoftAP mode, the transmitting end first selects a channel with less interference at the current location, so as to reduce channel interference during subsequent screen projection, make data transmission faster and smoother, and improve user experience.

[0115] Specifically, the sender can perform channel optimization in the following two ways:

[0116] Method 1: Obtain the current location of the sender, and select a channel that is not used locally according to the current location.

[0117] During spec...

Abstract

The invention discloses a screen projection apparatus and method. The apparatus comprises: a starting module used for starting a SoftAP mode of a sending terminal; a connection module used for broadcasting a Beacon frame containing specific information to the outside, so that a receiving terminal identifies the sending terminal according to the specific information and establishes a SoftAP connection with the sending terminal; and a projection module used for performing screen projection with the receiving terminal based on the SoftAP connection. According to the screen projection apparatus provided by the embodiment of the invention, the receiving terminal monitors the Beacon frame and quickly identifies the sending terminal according to the specific information in the Beacon frame, so that the receiving terminal quickly establishes the SoftAP connection with the sending terminal and performs the screen projection based on the SoftAP connection. The entire connection process is simple and fast, the screen start time is greatly shortened, the waiting time of a user is shortened, no excessive tedious user operation is imported, and the user experience is improved.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular, to a screen projection device and method. Background technique [0002] Wireless Fidelity Display (Wi-Fi Display, WFD) technology is a technology that enables a transmitter such as a smartphone and a notebook to wirelessly connect to a receiver such as a TV and a monitor. In the process of screen projection through WFD, the sender continuously sends the screen image of the local machine to the receiver as projection data, and the receiver also continuously receives the projection data and reproduces the screen image of the sender on the screen of the local machine. . [0003] The existing screen projection method is based on the wifi-direct protocol and RTSP (Real Time Streaming Protocol, real-time streaming protocol) for real-time streaming media broadcast. Therefore, before performing screen projection, it is first necessary to ensure that the wifi chip and...
