Detailed Description
The following describes the detailed implementation of the embodiments of the present invention with reference to the drawings. It should be understood that the detailed description and specific examples, while indicating and illustrating the invention, are not intended to limit the invention.
Fig. 1 is a schematic flow chart of a visual remote control method provided by an embodiment of the present invention, please refer to fig. 1, which is applied to a first terminal, wherein the first terminal may be, but is not limited to, a smart phone, a tablet computer, a portable wearable device, and the like, and is configured with a small-screen terminal with a smaller electronic screen. The visual remote control method may include the steps of:
step S110: and adding a local area network generated by the second terminal, and realizing real-time data intercommunication with the second terminal based on Socket.
The second terminal is a large screen terminal such as a smart television and projection. Referring to the example of fig. 2, the second terminal generates a local area network with an identity through its preconfigured SDK. The information (for example, two-dimension code) corresponding to the local area network can be displayed on a large screen of the second terminal, the first terminal can scan the information through the APP or the applet thereof, join the local area network, and realize real-time data intercommunication with the second terminal based on Socket technology. The second terminal starts the mDNS service through the preconfigured SDK, and generates a host name with a specific identifier as the identifier of the local area network. mDNS is a service that uses multicast technology, and mDNS services are understood to be services that enable devices to discover each other by sending multicast packets, based on the UDP protocol.
Preferably, the second terminal verifies the first terminal after detecting that the first terminal joins the signal of the local area network, and after verifying that the first terminal is a secure terminal, implements real-time data intercommunication with the first terminal based on Socket technology and sends a successful signal of connecting the local area network to the first terminal.
By way of illustration, a second terminal initializes Socket, establishes a streaming Socket service, binds with a local address and a port, and starts listening to a connection; after the first terminal acquires the IP and the port of the second terminal through the mDNS service, creating a Socket and connecting the IP and the port of the second terminal; and after the second terminal receives the connection notification, starting verification, and after the verification is passed, establishing a bidirectional communication channel between the first terminal and the second terminal so as to realize real-time data intercommunication.
For another example, after detecting that there is a signal that the first terminal joins the local area network, the second terminal opens the mDNS service by the SDK on the second terminal, and registers the following information with the mDNS service: "connectable second terminal", "IP (e.g., 192.168.1.11)", "port (e.g., 21)", while Socket service is opened on the 21 port. The first terminal also opens an mDNS service and sends a request to its mDNS service: "find connectable second terminal", the mDNS service of the first terminal will query other mDNS within the local area network. When the two terminals enter the same local area network, a second terminal with the IP of 192.168.1.11 and the port of 21 is found; after the first terminal finds out the IP and the port of the second terminal, socket bidirectional communication is established.
Step S120: and acquiring display information pushed by the second terminal, and rendering an interface according to the display information.

In this way, the APP or applet at the first terminal (small screen) can synchronize the pictures of the second terminal (large screen) in real time.
Step S130: and sending the acquired control instruction of the user on the interface to the second terminal so as to carry out visual remote control on the second terminal.
Referring to fig. 2, the first terminal can directly and accurately obtain a manipulation instruction (for example, touch-control selecting a certain function key, setting a play screen at a certain time point, game operation, etc.) of the interface, send the manipulation instruction to the second terminal, and the second terminal matches a corresponding visual remote control instruction in a preset operation instruction library, executes the visual remote control instruction, and displays an execution result in the second terminal (large screen). Preferably, in the process of executing the operation instruction by the second terminal, the process of executing the operation instruction and the corresponding execution result may be synchronized to the first terminal (small screen).
Accordingly, the embodiment of the invention connects the first terminal to the local area network generated by the second terminal, synchronously displays the picture of the second terminal in the application of the first terminal, and can directly and accurately visualize the picture of the remote control second terminal on the picture of the first terminal. Through the operation picture, the operation target is directly reached, and the troublesome operation of moving the remote controller (or the simulated remote controller, the virtual handle remote sensing and the like) step by step is abandoned. The embodiment of the invention provides the touch control of the small-screen terminal for the game on the large-screen terminal, so that a user can play more games on the large-screen terminal.
Fig. 3 is a schematic flow chart of a visual remote control method provided by the embodiment of the present invention, please refer to fig. 3, which is applied to a second terminal, wherein the second terminal may be, but is not limited to, a smart television, a projection, etc., and is configured with a large-screen terminal with a larger electronic screen. The visual remote control method may include the steps of:
step S210: and generating a local area network, and realizing real-time data intercommunication with the first terminal based on Socket when the first terminal joins the local area network.
The first terminal may be, but is not limited to, a smart phone, a tablet computer, a portable wearable device, and the like, and is configured with a small-screen terminal with a smaller electronic screen.
Preferably, the generating the local area network includes: and generating the local area network with the identification through the preconfigured SDK.
Referring to fig. 2, for illustration, information (e.g., two-dimensional code) corresponding to the local area network may be displayed on a large screen of the second terminal, and the first terminal may scan the information through its APP or applet, join the local area network, and implement real-time data interworking with the second terminal based on Socket technology. Preferably, the second terminal verifies the first terminal after detecting that the first terminal joins the signal of the local area network, and after verifying that the first terminal is a secure terminal, implements real-time data intercommunication with the first terminal based on Socket technology and sends a successful signal of connecting the local area network to the first terminal.
Step S220: pushing display information to the first terminal, and rendering an interface of the first terminal according to the display information by the first terminal.
The preferred display information in the embodiment of the invention can comprise page parameters, page layout, display content, content parameters and the like.
