Description
Technical Field
The application relates to the technical field of local area network interaction, such as a technology for controlling an intelligent media playing system in an HTTP mode, in particular to an intelligent media playing system and a control method of the intelligent media playing system in the local area network.
Background
The intelligent media player is Android equipment, has basically the same functions as an Android mobile phone, and is mainly used for playing multimedia such as video, audio and the like. As a player, it will typically input pictures to the display through an HDMI interface. Therefore, although the Android system is the same as a mobile phone, the most common operation mode is using a remote controller. However, the remote controller is far less convenient to operate than the hand touch operation, and when the application is used for editing, a large number of characters are input, the remote controller cannot move the cursor when the characters are input, the cursor falls on the letters to be input, and then the user presses the decision key for input. A chinese character or word is usually input with several letters, and the letters are generally distributed at various positions of the keyboard, so that the cursor is frequently moved to input a word, and the speed is conceivable.
The problem of cumbersome operation of the remote control is solved if the content of the media player can be displayed on the handset and the operation on the handset can make the same response on the media player. Therefore, the IP central control system has a prospect and is characterized by remote control. The remote control is an Android-based application program, and the main function is to provide an HTTP server and interact with other applications of the intelligent media player, so that other terminals can access data and remotely control other applications in the same network.
There are also remote Control systems on the market, such as the well-known Control4, whose function is to display multimedia data in a specific way. However, it is very limited, a Control4 device is expensive, it is very cumbersome to dock with Control4, it can be displayed normally according to a specific rule, and its content display mode is fixed, that is, you cannot display on the client in their own mode. In addition, control4 only supports specific applications to display specific contents, and cannot realize very fine manipulation functions.
There are other screen projection technologies, such as Micacast, which display the content of an android device in other devices, and this technology cannot realize a remote control function, but only projects the content, so that the problem that the media player is difficult to operate cannot be solved.
In addition, the patent application 201380000318.3 mentions a touch technology, which can enable the display screen to realize a touch function, so that the intelligent media player can also realize touch. This is very practical in some application scenarios, such as intelligent teaching, but for ordinary life scenarios, touching in front of the display screen undoubtedly hurts the eyes and is cumbersome to walk around.

If the browser is a web browser, the client is not required to be installed, and the browser can be operated directly.
Please refer to fig. 11. Fig. 11 illustrates a flow of web access. The specific description is as follows:
and the control center receives the startup broadcast of the android system, and the startup is self-started.
After the control center is started, related services such as control center service (service), device discovery server (joining device discovery multicast), WEB and the like are started.
The control center sends android BroadCast (BroadCast) to other applications, and the other applications register in the control center through data sharing after receiving the BroadCast.
The browser initiates access to the control center through the web server address.
And after receiving the web access request of the browser, the control center returns a static webpage to the browser.
After receiving the static webpage information, the browser sends a request to the control center.
After receiving the request, the control center analyzes the request, acquires the corresponding plug-in name registered by the application, inquires and acquires the related information of the application from the database, and binds the control service provided by the plug-in application according to the registration information of the plug-in application. After binding, the request is forwarded to the plug-in application.
And the plug-in application processes after receiving the request and sends the processing result to the control center.
The control center encapsulates the processing results and returns the processing results to the browser in the form of web.
And the browser receives the returned result and displays the result on the interface.
It should be noted that: other plug-ins are understood to be plug-in systems which may comprise at least one plug-in.
In summary, after the control center is started, the relevant service is started. And then, the control center sends the android broadcast to the plug-in system, and the plug-in system registers in the control center after receiving the broadcast. The user opens the web browser, inputs the address of the server, and returns the web page information after the control center receives the access request of the browser. The user can operate the returned webpage information, and the browser requests the operation to the control center; after receiving the request, the control center forwards the request to the plug-in system, the plug-in system processes the request and returns the processed result to the control center, and the control center returns the result to the browser end.
It should also be noted that: when the user accesses the control center using the browser, the user may manually input the server address, for example, input the IP address, or input the domain name of the server. And, if the browser has address information of the server already stored, the user can also dispense with the process of manual input.
Please refer to fig. 12. Fig. 12 illustrates the flow of an http access. The specific description is as follows:
and the control center receives the startup broadcast of the android system, and the startup is self-started.
After the control center is started, starting a control center service (service), starting an http server, starting a device discovery server (joining device discovery multicast), and starting a WEB service.
And then sending a BroadCast (BroadCast) to other applications, and registering the other applications in the control center through data sharing after receiving the BroadCast.
The terminal joins the device to find the multicast, sends UDP broadcast, and notifies the server in the multicast. And the server returns information to the terminal after receiving the information.
After receiving the information, the terminal sends a control application to the control center, and after receiving the request, the box user saves the authorization record and returns the result.
After the terminal acquires the permission, an http request is sent to the control center.
After receiving the request, the control center analyzes the request, acquires the corresponding plug-in name registered by the application, inquires and acquires the related information of the application from the database, and binds the control service provided by the plug-in application according to the registration information of the plug-in application. After binding, the request is forwarded to the plug-in application.
And the plug-in application processes after receiving the request and sends the processing result to the control center.
And the control center encapsulates the processing result and returns the processing result to the client in the form of http.
And the terminal receives the returned result and displays the result on the interface.
