The contents related to the interaction include contents to be shared to other interactive terminals and contents received from other interactive terminals. The content related to the interaction includes, for example, a screenshot of one or a combination of a desktop, a folder, a file, an icon, a window, a button, or a combination thereof or a combination of the screenshots. The content unrelated to the interaction includes content that is not intended to be shared with other interactive terminals in the interactive terminal, for example, a control interface that is not intended to be shared with other interactive terminals in the interactive terminal, such as the interface shown in fig. 3. In the present application, in order to clearly clarify content related to interaction and content unrelated to interaction, and avoid accidental confusion between content desired to be shared and content not desired to be shared, and enable content not desired to be shared accidentally, content related to interaction is displayed on one screen, content unrelated to interaction is displayed on the other screen of the interactive terminal, and other components and corresponding processing modes are provided to implement sharing of related content and avoiding sharing of unrelated content, as will be described in further detail below.
Fig. 1 is a diagram illustrating a multi-screen data interaction system according to an embodiment of the present invention, which includes: interactive terminal 10, interactive terminal 11, coding and controller 101, coding and controller 111, main display screen 100, secondary display screen 102, main display screen 110, and secondary display screen 112. The number of the interactive terminals can be arbitrarily set according to the needs of the user, and can be more than 2, for example, the interactive terminal 14, the secondary display screen 142, the primary display screen 140 and the coding and control device 141 are also shown in the figure.
The interactive terminal 10 is communicatively connected to the interactive terminal 11, for example via a network connection. The network may include a Wi-fi network, a bluetooth network, a Private Area Network (PAN), a Local Area Network (LAN), a Wide Area Network (WAN), IEEE 802.1x, an intranet, the internet, an extranet, and combinations thereof. The network may also include a digital cellular telephone network, which may include Global System for Mobile communications (GSM), General Packet Radio Service (GPRS), cdmaOne, CDMA2000, evolution-data optimized (EV-DO), enhanced data rates for GSM evolution (EDGE), Universal Mobile Telecommunications System (UMTS), Digital Enhanced Cordless Telecommunications (DECT), digital AMPS (IS-136/TDMA), Integrated digital enhanced network (iDEN), WiMAX, LTE advanced, Mobile Broadband Wireless Access (MBWA), IEEE 802.20. The network may be public access, private, virtual private, such as a VPN.
The figure shows the interactive terminal 10 establishing a connection with the interactive terminal 11 via the server 2. The main display screen 100 and the sub display screen 102 are respectively connected to the interactive terminal 10. The main display screen 100 is used for displaying content related to an interaction output by the interactive terminal 10, and the sub-display screen 102 is used for displaying content unrelated to the interaction output by the interactive terminal 10.
The main display screen 110 and the sub display screen 112 are respectively connected with the interactive terminal 11; the main display screen 110 is used for displaying content related to the interaction output by the interactive terminal 11, and the sub-display screen 112 is used for displaying content unrelated to the interaction output by the interactive terminal 11.
The encoding and control unit 101 is connected to the interactive terminal 10, and is configured to receive a content from the interactive terminal 10 that is the same as the content output to the main display screen 100, and when a user inputs an interactive sharing command to the interactive terminal 10, the interactive terminal 10 sends the interactive sharing command to the encoding and control unit 101, and the encoding and control unit 101 receives the interactive sharing command of the interactive terminal 10, encodes the content (that is, the content that is the same as the content output to the main display screen 100) into a first network stream signal according to the interactive sharing command, and outputs the first network stream signal, and if information carried in the interactive sharing command indicates that a sharing target is the interactive terminal 11, the first network stream signal is output to the interactive terminal 11. The interactive terminal 11 receives the first network stream signal output from the interactive terminal 10 and decodes it, and outputs the decoded content to the main display screen 110 and the encoding and controller 111. When a user inputs another interactive sharing command to the interactive terminal 11, the interactive terminal 11 sends the interactive sharing command to the coding and controller 111, and the coding and controller 111 receives the interactive sharing command of the interactive terminal 11, and codes the content (i.e., the same content as that output to the main display screen 110) into a second network stream signal according to the interactive sharing command and outputs the second network stream signal.
The interactive sharing command or the another interactive sharing command may include information such as ID information or an address of the target interactive terminal to be shared.
According to some embodiments of the present invention, when the interactive terminal 10 accepts another control command and changes the content related to the interaction in response to the control command, for example, accepts some text input or some plot information in the window, closes some windows, or drags the window to the secondary display screen (thereby becoming content not related to the interaction), or drags the window from the secondary display screen to the primary display screen (thereby becoming content related to the interaction), the interactive terminal outputs the changed content to the encoder and the controller at the same time, and then in response to a further received interaction sharing command, the encoder and the controller encodes the changed content into a network stream signal and outputs the network stream signal to the outside. According to some embodiments of the present invention, the encoding and controller 101 may also encode the received content into the first network stream signal in real time according to the update condition of the content related to the interaction output by the interactive terminal, and output the first network stream signal to the external, for example, the interactive terminal 11. The interactive terminal 11 receives the first network stream signal output from the interactive terminal 10 and decodes it, and outputs the decoded content to the main display screen 110 and the encoding and controller 111.
The interactive terminal 11 and the interactive terminal 10 are both configured with corresponding codes and controllers, and if the interactive terminal 11 is only used as a display side or a receiver side of interactive related contents, the interactive terminal 11 may not be configured with the codes and controllers 111.
According to some embodiments of the present invention, the coding and controller 101 and the main display screen 100 are connected with the interactive terminal 10 through a first split screen, so that the coding and controller 101 receives the same content from the interactive terminal 10 as that output to the main display screen 100; the coding and controller 111 and the main display screen 110 are connected with the interactive terminal 11 through the second split screen so that the coding and controller 111 receives the same contents from the interactive terminal 11 as output to the main display screen 110.
According to some embodiments of the present invention, in the interactive terminal 10, in addition to moving the content on the main display screen to the secondary display screen by dragging through the aforementioned dragging operation, the interactive terminal 10 may be caused to switch the content on the main display screen 100 to be displayed on the secondary display screen 102 (i.e., all the content is switched to be displayed on the secondary display screen 102) and/or switch the content on the secondary display screen 102 to be displayed on the main display screen (i.e., all the content is switched to be displayed on the main display screen) by setting a shortcut key or the like. Similarly, the interactive terminal 11 can receive and respond to a specific control command or input from the user, and display the content on the main display screen 110 to the sub-display screen 112; and/or, the interactive terminal 11 can receive and respond to a specific control command or input from the user to display the content on the secondary display screen 112 to the primary display screen 110 instead.
According to some embodiments of the present invention, the interactive terminal 10 may output information to other interactive terminals about the content on the main display screen thereon being shared to the interactive terminal 11, the information including: text list prompt, bubble popup prompt and icon shaking prompt; and/or the interactive terminal 10 subsequently denies the other interactive terminals' requests to retrieve content on their main display screen. An example of the text list prompt is shown in fig. 3, in which an interactive terminal 02 is being used by a user or an interactive terminal a is displayed on a display interface (a secondary display screen) of the interactive terminal 10, an editing area therein may display its private editing processing on a related signal, and such an action may be an operation that the user does not wish to share with other interactive terminals; the IDs in the text list may be subject to editing. The bubble popup prompts such as 'the content of the display screen has been captured, please pause the use', etc.
According to some embodiments of the present invention, the interactive terminal 10 may output to the first sub-display screen information about content on the first main display screen being shared to the second interactive terminal, the information including: text list prompt, bubble popup prompt and icon shaking prompt; and/or the first interactive terminal does not respond to the operation of the content on the first main display screen, wherein the operation comprises a keyboard, a mouse and a touch operation.
The present application further provides a multi-screen data interaction method, and referring to fig. 2, a flowchart of the multi-screen data interaction method according to the embodiment of the present invention is shown.
The method includes the following steps S1-S3:
s1, outputting content relevant to interaction to a first main display screen and a first coding and control device, and outputting content irrelevant to interaction to a first auxiliary display screen.
The execution subject of step S1 may be the aforementioned first interactive terminal.
