Exemplary method
The embodiment provides a screen projection display method which can be applied to a small-screen intelligent terminal for communication. As shown in fig. 1, the method includes the following steps:
s100, identifying a wireless screen projection protocol supported by a small-screen intelligent terminal, and executing initialization operation according to the wireless screen projection protocol to obtain an initialization result;
specifically, wireless screen-throwing protocols supported by each small-screen intelligent terminal are different, the small-screen intelligent terminals supporting different wireless screen-throwing protocols cannot be unified or compatible due to different wireless screen-throwing protocols, when a user needs to send data in the small-screen intelligent terminals supporting different wireless screen-throwing protocols to a large-screen intelligent terminal, due to the existing non-uniformity or incompatibility, the user cannot throw the data in a plurality of small-screen intelligent terminals supporting different wireless screen-throwing protocols into one large-screen intelligent terminal, and the display target of throwing one screen to one device by a plurality of devices can be achieved only by adding the large-screen intelligent terminal. In this embodiment, a plurality of small-screen intelligent terminals supporting different wireless screen projecting protocols can coexist to achieve the purpose that a plurality of devices can project a screen to one device to display data, specifically, the application system first identifies the wireless screen projecting protocols supported by the small-screen intelligent terminals, for example, the Android mobile phone and the Windows notebook computer are Miracast protocols, the IOS mobile phone is AirPlay protocols, and the like, and then performs initialization operation on the wireless screen projecting protocols according to the wireless screen projecting protocols to obtain corresponding initialization results of the different wireless screen projecting protocols.
In order to obtain an initialization result, the method comprises the following steps of identifying a wireless screen projection protocol supported by the small-screen intelligent terminal, and initializing the wireless screen projection protocol:
step S101, identifying a Miracast protocol, and initializing a P2P network according to the Miracast protocol;
and step S102, identifying an AirPlay protocol, and initializing the AP network according to the AirPlay protocol.
In practice, when the Miracast protocol is acquired, the P2P network needs to be initialized according to the Miracast protocol, and the P2P network refers to that participants of the network share a part of hardware resources (processing capacity, storage capacity, network connection capacity, printer, etc.) owned by the participants, and these shared resources provide services and contents through the network and can be directly accessed by other Peer nodes (peers) without going through intermediate entities. The participants in this network are both providers (servers) and acquirers (clients) of resources, services and content. When the AirPlay protocol is identified, the AP network needs to be initialized according to the AirPlay protocol. An AP network, i.e. a wireless access point, which is used for a wireless switch of a wireless network, is also the core of the wireless network. The wireless AP is an access point for a mobile computer user to enter a wired network, is mainly used in broadband families, buildings and parks, and can cover dozens of meters to hundreds of meters. A wireless AP (also called a session point or an access bridge) is a broad name, and includes not only a simple wireless access point (wireless AP), but also a generic name of devices such as a wireless router (including a wireless gateway and a wireless bridge).
The embodiment provides a screen projection display method which can be applied to a small-screen intelligent terminal for communication. As shown in fig. 1, the method includes the following steps:
s200, monitoring network connection request information sent by the small-screen intelligent terminal according to the initialization result to obtain a network connection state result.
Specifically, after the application system obtains the initialization result, that is, after the wireless screen-casting protocols of different small-screen intelligent terminals are identified, the wireless screen-casting protocol is initialized, a monitoring state is started, whether the small-screen intelligent terminal sends connection request information is monitored, and a WfdService service is started at the same time, wherein the WfdService is a service program which can be understood as running in the background of the Android system, can be used whenever needed, and can wait in the background when not needed, so that the overall running of the application is not affected. When the WfdService service receives a message that the device is successfully connected, a corresponding thread is created to process the interaction with the connection device (no thread is available at first), finally, the data stream transmitted by the connection device is encapsulated into a certain URL (such as a pipe), and the created thread is submitted to a thread pool (created during initialization) for management.
In order to obtain the network connection state, monitoring network connection request information sent by the small-screen intelligent terminal according to the initialization result, and obtaining the network connection state result comprises:
s201, when a P2P network is initialized according to the Miracast protocol, monitoring network connection request information sent by a small-screen intelligent terminal supporting the Miracast protocol to obtain a first network connection state result;
s202, when the AP network is initialized according to the AirPlay protocol, monitoring network connection request information sent by a small-screen intelligent terminal supporting the AirPlay protocol to obtain a second network connection state result.
Specifically, the Android mobile phone and the Windows notebook computer support a Miracast protocol, the IOS mobile phone supports an AirPlay protocol, and when the application system obtains network connection states of different small-screen intelligent terminals and large-screen intelligent terminals, it needs to monitor network connection request information sent by the small-screen intelligent terminal corresponding to the wireless screen-casting protocol supported by the application system. That is, when the P2P network is generated according to the Miracast protocol, monitoring network connection request information sent by the small-screen intelligent terminal supporting the Miracast protocol, and obtaining a first network connection state result of the small-screen intelligent terminal and the large-screen intelligent terminal supporting the Miracast protocol according to the network connection request information sent by the small-screen intelligent terminal; and when the AP network is generated according to the AirPlay protocol, acquiring the network connection state of the small-screen intelligent terminal and the large-screen intelligent terminal which support the AirPlay protocol, and obtaining a second network connection state result of the small-screen intelligent terminal and the large-screen intelligent terminal which support the AirPlay protocol.
In order to obtain a first network connection state result, the monitoring network connection request information sent by the small-screen intelligent terminal supporting the Miracast protocol, and obtaining the first network connection state result includes the following operations: acquiring node information of a small-screen intelligent terminal supporting a Miracast protocol; acquiring node information of a large-screen intelligent terminal; when the node information of the small-screen intelligent terminal supporting the Miracast protocol is the same as the node information of the large-screen intelligent terminal, the small-screen intelligent terminal supporting the Miracast protocol and a first network connection state result between the large-screen intelligent terminals are connected.
Specifically, when a Windows notebook computer supporting the Miracast protocol needs to project data to a small-screen intelligent terminal, network connection request information is sent to the large-screen intelligent terminal first, then node information of the small-screen intelligent terminal supporting the Miracast protocol, such as a Windows notebook computer, is obtained, then node information of the large-screen intelligent terminal, such as an intelligent large screen, is obtained, when the network connection request information sent by the small-screen intelligent terminal supporting the Miracast protocol is monitored, and when the node information of the small-screen intelligent terminal supporting the Miracast protocol is the same as the node information of the large-screen intelligent terminal, a first network connection state result between the small-screen intelligent terminal supporting the Miracast protocol and the large-screen intelligent terminal is obtained as connected, when the network connection request information sent by the small-screen intelligent terminal supporting the Miracast protocol is not monitored or when the node information of the small-screen intelligent terminal supporting the Miracast protocol is not the same as the node information of the large-screen intelligent terminal, and showing that the network connection state result of the small-screen intelligent terminal and the large-screen intelligent terminal is unconnected.
In order to obtain a second network connection state result, the monitoring network connection request information sent by the small-screen intelligent terminal supporting the AirPlay protocol, and obtaining the second network connection state result includes the following operations: acquiring local area network information of a small-screen intelligent terminal supporting an AirPlay protocol; when network connection request information sent by a small-screen intelligent terminal supporting an AirPlay protocol is monitored, and when the local area network information of the small-screen intelligent terminal supporting the AirPlay protocol is the same as the local area network information of the large-screen intelligent terminal, a second network connection state result between the small-screen intelligent terminal supporting the AirPlay protocol and the large-screen intelligent terminal is obtained and is connected.
Specifically, when the IOS mobile phone supporting the AirPlay protocol needs to project data to a small-screen intelligent terminal, network connection request information is sent to the large-screen intelligent terminal, then local area network information of the small-screen intelligent terminal supporting the AirPlay protocol, such as the IOS mobile phone, is obtained, and then local area network information of the large-screen intelligent terminal, such as an intelligent large-screen, is obtained, such as the IP of the IOS mobile phone: "192.168.1.100", and IP of the smart large screen: "192.168.1.101", when the local area network information of the small-screen smart terminal supporting the AirPlay protocol is the same as the local area network information of the large-screen smart terminal, the result of the second network connection state between the small-screen smart terminal supporting the AirPlay protocol and the large-screen smart terminal is obtained as connected, that is, when the IP: "192.168.1.100", and IP of the smart large screen: "192.168.1.101", which indicates that the network connection status result of the small-screen intelligent terminal and the large-screen intelligent terminal is connected, and when the IP of the IOS mobile phone: "192.168.1.100", and IP of the smart large screen: "192.168.2.17", it indicates that the network connection status of the small-screen intelligent terminal and the large-screen intelligent terminal results in no connection.
The embodiment provides a screen projection display method which can be applied to a small-screen intelligent terminal for communication. As shown in fig. 1, the method includes the following steps:
s300, projecting the data of the plurality of small-screen intelligent terminals to the large-screen intelligent terminal according to the network connection state result so as to display the data in the large-screen intelligent terminal.
Specifically, after the application system obtains the connection state of the small-screen intelligent terminal and the large-screen intelligent terminal supporting different wireless screen projection protocols, the data of the small-screen intelligent terminals supporting the different wireless screen projection protocols can be projected to the large-screen intelligent terminal, and finally the data is displayed in the large-screen intelligent terminal. For example, when the application system obtains that the Android mobile phone and the Windows notebook computer supporting the Miracast protocol are connected with the large-screen intelligent terminal and monitors that the IOS mobile phone supporting the AirPlay protocol is also connected with the large-screen intelligent terminal, the data of the Android mobile phone and the Windows notebook computer supporting the Miracast protocol and the IOS mobile phone supporting the AirPlay protocol can be simultaneously projected to the large-screen intelligent terminal, so that the data of a plurality of devices can be displayed on the large-screen intelligent terminal.
In order to realize the data projection from the small-screen intelligent terminal to the large-screen intelligent terminal supporting a plurality of different wireless screen projection protocols, the data projection from the plurality of small-screen intelligent terminals to the large-screen intelligent terminal according to the network connection state result so as to realize the display of the data in the large-screen intelligent terminal comprises the following steps:
s301, when a first network connection state result between the Miracast protocol-supporting small-screen intelligent terminal and the large-screen intelligent terminal is connected, sending first data of the Miracast protocol-supporting small-screen intelligent terminal to the large-screen intelligent terminal in a wireless network mode, and triggering a player of the large-screen intelligent terminal to display the data in the large-screen intelligent terminal;
