S400, receiving and acquiring an NFC screen projection instruction, automatically scanning a television receiving end preset with an NFC label to trigger response through an NFC screen projection protocol, and detecting a matched hot spot;
in the embodiment of the invention, when the screen projection function of the mobile phone is turned on, if the NFC screen projection is selected, the NFC screen projection instruction is selected, the television receiving end which is preset with the NFC label to trigger response is automatically scanned through the NFC screen projection protocol, and the matched hot spot is detected.
Namely, in the embodiment of the invention, if the mobile phone starts the NFC module and selects the NFC screen projection function, the television receiving end preset with the NFC tag trigger response is automatically scanned through the NFC screen projection protocol, and the matched hot spot is detected.
According to the embodiment of the invention, bidirectional identification and connection can be automatically adopted through the NFC module. Operating in the 13.56MHz frequency range over a distance of 20 cm. The wireless network can be quickly and automatically established, and a virtual connection is provided for cellular equipment, Bluetooth equipment and Wi-Fi equipment, so that the electronic equipment can communicate in a short-distance range.
And S500, receiving a connection request returned by the television receiving end with the preset NFC label, automatically connecting and sending screen projection data.
In the embodiment of the invention, when the television receiving end with the preset NFC label is selected as the screen projection receiving end through NFC scanning, the mobile phone receives the connection request returned by the television receiving end with the preset NFC label when the television receiving end confirms, and the mobile phone automatically connects and sends screen projection data.
In specific implementation, the mobile phone can be in contact with a television receiving end with a preset NFC label through the NFC module and establish NFC connection; and when the automatic connection is successful, performing point-to-point network data transmission and sending screen projection data to the television receiving end. In the embodiment of the invention, the NFC modules of the mobile phone and the television receiving end are preset and work in a frequency range of 13.56MHz within a distance of 20 cm; and automatically establishing a wireless network to transmit screen projection data.
Therefore, the invention can simulate the user operation through the screen projection of the NFC module, automatically complete the function of scanning connection, simplify the operation steps, and complete the matching of two ends through the function used by automatic matching, thereby realizing the aim of automation.
The invention is further illustrated in detail by the following specific application examples:
in the method for processing screen projection of the mobile phone and the television according to the specific application embodiment, as shown in fig. 3, the NFC function is started at both the mobile phone and the television, and the NFC screen projection protocol is set to have the NFC screen projection function.
Step S11, finding a service agreement by the mobile phone, for example, detecting that the current process is a screen-casting service.
Step S12, starting scanning, and scanning through an NFC module;
step S13, judging whether a hotspot is scanned, namely whether a television terminal with an NFC screen projection function is scanned, if so, entering step S14, and if not, entering step S16;
and step S14, connecting by using the currently searched squint, namely connecting by using the currently scanned television with the NFC screen projection function.
And S15, judging whether the connection is successful, if the connection is successful, performing screen projection operation, if the screen projection operation is completed, entering the step S16, and if not, directly entering the step S16.
And step S16, end.
The invention provides a screen-casting processing method for a mobile phone and a television, which adopts an NFC protocol added on terminals of two screen-casting parties, and as long as the television opens an application, the mobile phone approaches to the side of the television, and automatically completes operations such as scanning, connection and the like along with one sound of a ticker, and is as simple as card swiping. The invention adds a more convenient and faster screen projection operation mode on the prior art, so that the user can use the screen projection device more conveniently, the screen projection operation is more convenient and faster, and convenience is provided for the user to use the screen projection device.
The technical key point is that the NFC module is added into the screen projection, so that the operation is simpler, the user feels cool when using the NFC module, and complicated operation steps are omitted, thereby being more beneficial to the popularization of the technology.
