Detailed Description
The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the present application without making any inventive effort, shall fall within the scope of the present application.
In the related art, in order to realize the cross-screen display of information, an input terminal and a display terminal are required to be connected by a data line, or a client for receiving information is required to be downloaded in the display terminal in advance, and then the input terminal transmits a section of edited text information to the display terminal through the data line or the client of the display terminal by receiving a transmission instruction of a user, so that the display terminal can display the section of text information. However, when the text information is displayed across the screen in the mode, timeliness is low, and the text information display efficiency is low.
In view of this, the present inventors have established communication between a browser of a display terminal and a server in a long connection and also established communication between an input terminal and a server in a long connection in order to improve timeliness of information presentation, thereby maintaining a stable data transmission path among the input terminal, the server, and the browser of the display terminal, so that the input terminal and the display terminal are bound by the server. And then the input terminal transmits the information input by the user to the browser of the display terminal in real time through the server, so that the display terminal displays the information input by the user to the input terminal in real time through the browser. Therefore, timeliness of information display is improved, and convenience of information display is also improved.
Referring to fig. 1, fig. 1 is an information interaction schematic diagram of a cross-screen display system according to an embodiment of the present application. As shown in fig. 1, the system includes an input terminal, a server, and a display terminal. The input terminal can be a terminal device such as a mobile phone, a tablet computer, a notebook computer and the like, the display terminal can be a terminal device such as a projector, a television, an LED screen and the like which are connected with the computer, and the display terminal can also be an intelligent device such as a notebook computer, a desktop computer and the like which is provided with a display module and a calculation module. The input terminal and the display terminal may be located in the same spatial environment, for example in the same conference room. The input terminal and the display terminal may also be located in different spatial environments, for example, the input terminal is located in an interview environment of city a and the display terminal is located in an office environment of city B.
The input terminal and the display terminal can be multiple, and one input terminal can be bound with one or more display terminals in a period of time and can keep a stable data transmission channel; a display terminal may also bind with multiple input terminals over a period of time and maintain a stable data transmission path. For simplicity of the schematic diagram, only one input terminal and one display terminal are shown in fig. 1.
In order to establish a stable data transmission channel between the input terminal and the display terminal so as to realize stable and real-time cross-screen display, the server needs to be relied on to establish long-connection communication with the input terminal and the display terminal browser at the same time, so that the input terminal can communicate with the display terminal through the server to form the stable data transmission channel.
By way of example, as shown in fig. 1, a data channel may be established between an input terminal and a display terminal in particular by:
and the display terminal displays the webpage of the server-side website after opening the browser and accessing the server-side website through the browser. The display terminal registers the display terminal's own PC with the server and requests the server to issue a Token. The server side responds to the request of the display terminal, randomly generates a token for the display terminal, and transmits the token to the display terminal. After receiving the token, the display terminal caches the token. And the display terminal converts the token into text form or two-dimensional code information and displays the text form or the two-dimensional code information through a webpage in a browser. If the token is displayed in a text form, a user can manually input the text to the input terminal, and if the token is displayed in a two-dimensional code form, the user can scan the two-dimensional code by using the input terminal, so that the input terminal can acquire the token information. After the input terminal acquires the token information, the token information is sent to the server, and after the server receives the token information, the input terminal and the display terminal can be bound by comparing the token information, and the binding relation is stored. Thus, the input terminal can communicate with the display terminal through the server, and a stable data transmission channel is formed.
Therefore, the input terminal can transmit the acquired information to the display terminal through the server in real time based on the data transmission channel, and the cross-screen display is realized.
By way of example, as shown in fig. 1, the data transmission from the input terminal to the display terminal can be realized in particular by:
the input terminal collects information input by a user in real time and transmits the collected information to be displayed to the server in real time. When the input terminal sends information to be displayed to the server, the input terminal also sends identification information (such as an input terminal ID, token information, etc.) of the input terminal to the server. After receiving the information to be displayed and the identification information of the input terminal, the server matches the identification information of the corresponding display terminal from the stored binding relations according to the identification information, so as to determine the target display terminal, and the server forwards the information to be displayed to the target display terminal. After receiving the information to be displayed, the target display terminal displays the information to be displayed through a webpage by a browser of the target display terminal, so that real-time cross-screen display is realized, and timeliness of information display is improved.
In addition, the input terminal and the display terminal may also mutually transmit control instructions to realize the function of mutual control.
By way of example, as shown in fig. 1, the mutual control between the input terminal and the display terminal may be achieved in particular by:
the input terminal may send a control instruction to the server, where the control instruction may be generated by the input terminal after receiving an operation of the user, or may be automatically generated by the input terminal according to a preset system or software. When the input terminal sends a control instruction to the server, the input terminal also sends identification information (such as an input terminal ID, token information, etc.) of the input terminal to the server. After receiving the control instruction and the identification information of the input terminal, the server matches the identification information of the corresponding display terminal from the stored binding relations according to the identification information, so as to determine the target display terminal, and the server forwards the control instruction to the target display terminal. And after receiving the control instruction, the target display terminal enables the browser to execute the control instruction.
The display terminal may send a control instruction to the server, where the control instruction may be generated by the display terminal after receiving an operation of a user, or may be automatically generated by the display terminal according to a preset system or browser. When the display terminal sends a control instruction to the server, the display terminal also sends identification information (such as an input terminal ID, token information, etc.) of the display terminal to the server. After receiving the control instruction and the identification information of the display terminal, the server matches the identification information of the corresponding input terminal from the stored binding relations according to the identification information, so as to determine the target input terminal, and the server forwards the control instruction to the target input terminal. And after receiving the control instruction, the target input terminal executes the control instruction.
In the cross-screen display system provided in this embodiment, the input terminal may communicate with the server through a pre-installed client based on the C/S architecture; and the server can also communicate with the server through a browser based on the B/S architecture. The communication connection mode among the input terminal, the service terminal and the display terminal is suitable for long connection mode, so as to keep the durability and stability of the data transmission channel. The network form on which the whole cross-screen display system is based can be the Internet, a wide area network, a metropolitan area network, a local area network or a personal area network, or can be a wireless network such as WiFi, bluetooth and the like. In addition, the whole cross-screen display system can be based on various network forms at the same time, for example, connection between the input device and the server can be realized based on WiFi and Internet, and connection between the server and the display terminal can be realized based on local area network.
In the above, the embodiment of the application describes the proposed cross-screen display system from the whole perspective. In the following, the method of cross-screen display will be described from each angle of the cross-screen display system.
Referring to fig. 2, fig. 2 is a flowchart of a method for cross-screen display according to an embodiment of the present application, where the method is applied to a server in a cross-screen display system. As shown in fig. 2, the method comprises the steps of:
Step S22: establishing long connection communication with a browser of the display terminal, and establishing long connection communication with the input terminal, so that the input terminal communicates with the display terminal through the server;
step S24: receiving information to be displayed, which is transmitted by the input terminal in real time, wherein the information to be displayed is information input to the input terminal by a user;
step S26: and sending the information to be displayed to a browser of the display terminal, so that the information to be displayed is displayed on the display terminal in real time through the browser.
In this embodiment, long connection communication generally means that a plurality of data packets can be continuously transmitted over one connection, and both sides can transmit a link detection packet if no data packet is transmitted during connection maintenance.
In this embodiment, the input terminal may communicate with one or more display terminals through the server, in other words, one input terminal may maintain a binding relationship with one or more display terminals. When the input terminal only maintains a binding relation with one display terminal, the server only forwards the information to be displayed to the uniquely-bound display terminal after receiving the information to be displayed sent by the input terminal. When the input terminal and the display terminals maintain binding relation, the server forwards the information to be displayed to the binding display terminals after receiving the information to be displayed sent by the input terminal, so that the binding display terminals can display the information to be displayed in real time by utilizing respective browsers.
In this embodiment, the display terminal may also communicate with a plurality of input terminals through the server, in other words, one display terminal may maintain a binding relationship with a plurality of input terminals. In this case, one implementation is: the page displayed by the browser of the display terminal can be divided into a plurality of sub-screens, and each sub-screen is used for displaying information to be displayed sent by one input terminal in real time.
Another embodiment is: the browser of the display terminal displays a group chat interface for displaying information to be displayed, which is sent by each of the plurality of input terminals, in real time. Each input terminal carries the head portrait and/or name corresponding to the input terminal at the front end or the rear end of each piece of display information in the group chat interface. The group chat interface sequentially displays the information to be displayed sent by each of the plurality of input terminals according to the sequence of the information sent by each of the input terminals, and the group chat interface displays the information to be displayed, which is received by the display terminal most recently, at the forefront end. The embodiment can be applied to conference scenes, each conference participant is provided with an input terminal, the conference participant inputs voice through the input terminal provided by the conference participant, the input terminal sends the voice to the server, and the server sends the text information to a browser of the display terminal as information to be displayed after recognizing the voice into the text information, so that the group chat interface can display the text information. In this embodiment, for step S22, the following steps may be specifically performed: receiving a connection request sent by the display terminal through a browser; responding to the connection request, and sending first token information to a browser of the display terminal so as to display the first token information on the display terminal through the browser; receiving second token information sent by the input terminal, wherein the second token information is information which is input to the input terminal by a user according to the first token information when the display terminal displays the first token information; and in response to the second token information, binding the input terminal for transmitting the second token information with the display terminal for receiving the first token information, so that the input terminal can communicate with the display terminal through the server.
Specifically, for step S22, the interaction process of the input terminal, the server side, and the display terminal in the above-mentioned cross-screen display system during the communication establishment period will not be repeated here.
In this embodiment, the information to be displayed sent by the input terminal in real time may be text information collected by the input terminal. For example, the input terminal may encapsulate and send the character newly input by the user to the server at intervals of a short time, for example, at intervals of several hundred milliseconds or several seconds, according to the speed of inputting the text by the user, so as to realize real-time transmission of the information to be displayed. Or, for example, after receiving a typing instruction (such as a carriage return character or a space character) input by the user, the input terminal encapsulates and sends one or more characters just typed by the user to the server so as to realize real-time sending of information to be displayed.
In this embodiment, the information to be displayed sent by the input terminal in real time may also be audio acquired by the audio acquisition module of the input terminal. Thus, referring to fig. 3, fig. 3 is a flowchart of a method for cross-screen display according to another embodiment of the present application. The method further comprises the steps of:
step S25: performing voice recognition on the audio to obtain text information;
Step S26-1: and sending the text information serving as the information to be displayed to a browser of the display terminal, so that the text information is displayed on the display terminal in real time through the browser.
Taking an interview scene as an example, during interview, a user takes a mobile phone as an input terminal to collect audio of an interviewee. The mobile phone takes the audio of the interviewee as information to be displayed and transmits the information to the server in real time. After receiving the audio, the server performs voice recognition on the audio, so as to obtain text information corresponding to the audio. And then sending the text information to a browser of the display terminal as the information to be displayed, so that the text information is displayed on the display terminal in real time through the browser.
In the step S25 and the step S26-1, through the recognition and conversion of the audio by the server, on one hand, the application range of the cross-screen display system can be enlarged, so that the cross-screen display system can be applied to interviews, conferences, daily communications and other scenes, and the audio collected by the input terminal can be converted into a text form, so that the audio is displayed by the browser page of the display terminal. On the other hand, the computing capacity of the server is generally far higher than that of the input terminal, so that voice recognition is carried out on the audio at the server, the voice recognition rate and accuracy are high, and the display efficiency and accuracy of the information are further guaranteed.
In this embodiment, after receiving the information to be displayed sent by the input terminal, the server may first determine the information type of the information to be displayed, and if the server determines that the information type of the information to be displayed is audio information, then perform speech recognition on the audio information by executing step S25 to obtain corresponding text information, and then send the text information as the information to be displayed to the browser of the display terminal by step S26-1. If the server determines that the information to be displayed is text information, the text information can be directly sent to the browser of the display terminal as the information to be displayed without going through step S25. Therefore, the cross-screen display system provided by the application has a larger application range, and real-time cross-screen display can be realized no matter whether the text information or the audio information is acquired by the input terminal.
Furthermore, as shown in fig. 4, the method may further include the steps of:
step S27: and returning the text information to the input terminal so as to display the text information in real time through the input terminal.
According to the above example, after the server receives the audio sent by the mobile phone and performs voice recognition on the audio, text information corresponding to the audio is obtained, the text information is returned to the mobile phone, so that the mobile phone and the display terminal can display the text information at both ends at the same time. The method realizes one-end input and two-end display, so that respective users of the input terminal and the display terminal can read, adjust, store and the like text information recognized by voice.
In addition, in order to improve interactivity between the input terminal and the display terminal, the input terminal may control the display terminal, or the display terminal may control the input terminal, referring to fig. 5, fig. 5 is a flowchart of a method for cross-screen display according to another embodiment of the present application. The method further comprises the steps of:
step S28-1: receiving a first control instruction sent by the input terminal;
step S28-2: and forwarding the first control instruction to the browser of the display terminal so as to enable the browser of the display terminal to execute the first control instruction.
Step S28-3: receiving a second control instruction sent by the display terminal through a browser;
step S28-4: and forwarding the second control instruction to the input terminal so that the input terminal executes the second control instruction.
In this embodiment, the first control instruction sent by the input terminal or the second control instruction sent by the display terminal may be a control instruction such as pause, stop, or close. For example, when the first control instruction sent by the input terminal is a pause instruction, the server side forwards the pause instruction to the browser of the display terminal, and the browser executes the pause instruction, so that the cross-screen display function is paused.
In this embodiment, how the server forwards the first control instruction or the second control instruction may refer to an interaction process of the input terminal, the server, and the display terminal in the above-mentioned cross-screen display system after the communication connection is established, which is not described herein again.
Referring to fig. 6, fig. 6 is a flowchart of a method for cross-screen display according to another embodiment of the present application, where the method is applied to a display terminal in a cross-screen display system. As shown in fig. 6, the method comprises the steps of:
step S62: establishing long connection communication with the server by using a browser, so that the server communicates with the input terminal through the server after establishing long connection communication with the input terminal;
step S64: the browser is utilized to receive information to be displayed, which is sent by the server side, in real time, wherein the information to be displayed is information which is input to the input terminal by a user and is sent to the server side in real time by the input terminal;
step S66: and displaying the information to be displayed in real time through the browser.
In this embodiment, long connection communication generally means that a plurality of data packets can be continuously transmitted over one connection, and both sides can transmit a link detection packet if no data packet is transmitted during connection maintenance.
In this embodiment, the input terminal may communicate with one or more display terminals through the server, in other words, one input terminal may maintain a binding relationship with one or more display terminals. When the input terminal only maintains a binding relation with one display terminal, the server only forwards the information to be displayed to the uniquely-bound display terminal after receiving the information to be displayed sent by the input terminal.
