The user may input a user instruction through a key on a remote controller, voice input, control panel input, etc., to control the display apparatus 200.
In some embodiments, the smart device 300 (e.g., mobile terminal, tablet, computer, laptop, etc.) may also be used to control the display device 200. For example, the display device 200 is controlled using an application program running on the smart device.
In some embodiments, the display device 200 may also be controlled in a manner other than the control apparatus 100 and the smart device 300, for example, the voice command control of the user may be directly received by a module configured inside the display device 200 to obtain a voice command, or may be received by a voice control device provided outside the display device 200.
In some embodiments, the display device 200 is also in data communication with a server 400. The display device 200 may be allowed to be communicatively connected through a Local Area Network (LAN), a Wireless Local Area Network (WLAN), and other networks. The server 400 may provide various contents and interactions to the display apparatus 200. The server 400 may be a cluster or a plurality of clusters, and may include one or more types of servers.
In some embodiments, the display device may directly enter a display interface of a signal source selected last time after being started, or a signal source selection interface, where the signal source may be a preset video-on-demand program, or may be at least one of an HDMI interface, a live tv interface, and the like, and after a user selects different signal sources, the display may display contents obtained from different signal sources.
In some embodiments, the display device may be launched to enter a home page of the display device, where an interface of the home page may display the installed applications. The installed applications may include a conferencing application. The whiteboard function is an important function of the conference application, a whiteboard control can be arranged on an interface of the conference application, the whiteboard interface can be accessed by clicking the whiteboard control, and all conference members can perform some operations on the whiteboard, such as marking, inserting characters and the like, on the whiteboard interface.
In some embodiments, a conference application may include version 1 and version 2, where version 1 may also be referred to as a first version, a whiteboard function integrated with the conference application of the first version is a function developed by a third party, and the third party may be provided with an IM service (instant messaging server), which is hereinafter referred to as a third party communication server. After the whiteboard function is started in a conference, each terminal of the conference member can establish long connection with the third-party communication server, and vector data input by the user on the terminal is sent to the third-party communication server. The third-party communication server shares the vector data to the terminals of other conference members, so that the other conference members can see the operation of other users on the terminals of the third-party communication server.
In some embodiments, version 2 may also be referred to as a second version. The second version of the conference application integrated whiteboard function includes a whiteboard function self-developed by the display device side and a function developed by a third party, and the display device side may be provided with a whiteboard communication server. Illustratively, the whiteboard functions developed by the third party may include functions of drawing lines, drawing graphics, inserting characters and the like, and the functions of the self-developed whiteboard may include functions of drawing lines, drawing graphics, inserting characters, inserting pictures, zooming, erasing, annotating and the like, which belong to different whiteboard operation types respectively.
In some embodiments, to facilitate differentiation, the third party communication server may also be referred to as a first whiteboard server, meaning that the server provides data services for a first version of the whiteboard; the whiteboard communication server on the display device side may also be referred to as a second whiteboard server, which indicates that the server provides data service for a second version of whiteboard, where the first version of whiteboard is a whiteboard of the first version of conference application, and the second version of whiteboard is a whiteboard of the second version of conference application.
In some embodiments, in a conference in which all terminals provided with the first version of conference application participate, if the whiteboard function is started in the conference, all terminals joining the whiteboard can establish long connection with the first whiteboard server, and operation data on the respective terminals is shared to other terminals joining the whiteboard through the first whiteboard server, so that cooperation through a third-party whiteboard is realized.
In some embodiments, the long connection established between the terminal and the first whiteboard server may be a websocket connection, and after the websocket connection is established, a long connection channel of an mqtt protocol may be formed between the terminal and the first whiteboard server, where the channel may perform transmission of vector data, and the vector data may be a json character string.
Taking the operation of drawing a line on the third-party white board by the user as an example, after the user draws a line on the white board of one terminal, the terminal converts the attribute information of the line into a json character string, wherein the attribute information may include the x \ y start-stop coordinate of the line, the width of the line and the color of the line. The method comprises the steps that a json character string is sent to a first white board server through a long connecting channel based on mqtt by the terminal, the first white board server forwards the json character string to other terminals added into the white board, the other terminals added into the white board can restore the json character string into operation data after receiving the json character string, and therefore the lines are displayed on the respective white boards.
In some embodiments, in a conference in which all terminals provided with the second version of conference application participate, if the whiteboard function is started in the conference, all the participating terminals may establish long connection with the second whiteboard server, and share the operation data on the respective terminals with other participating terminals through the second whiteboard server.
In some embodiments, the long connection established by the conferencing application with the second whiteboard server may be a websocket connection, which may enable transmission of vector data, which may also be a json string.
Or, for example, when the user draws a line, the terminal operated by the user converts the attribute information of the line into a json character string of the line corresponding to the second whiteboard server. The converted json character string is sent to a second whiteboard server through a long connecting channel based on mqtt by the terminal, the json character string is forwarded to other terminals added into the whiteboard by the second whiteboard server, and the json character string can be restored into operation data after the json character string is received by the other terminals added into the whiteboard, so that the line is displayed on the respective whiteboard.
In some embodiments, if the user has selected the automatic upgrade in the settings options of the conferencing application, the conferencing application may automatically upgrade the application version of the conferencing application from the first version to the second version.
In some embodiments, if the user does not check the automatic upgrade in the setting options of the conference application, the conference application may not automatically upgrade the application version of the conference application from the first version to the second version, but may manually upgrade the application version from the first version to the second version by the user.
In some embodiments, the conference application may be configured to pop up a version upgrade prompting window if the current conference version is the first version after the user starts the conference application or after the user starts the whiteboard function, the version upgrade prompting window may be provided with an acceptance control and a rejection control, the acceptance control may be configured to, in response to a user click, jump to a link address of a second version installation file of the conference application to upgrade the conference application to the second version, and the rejection control may be configured to, in response to the user click, not perform version upgrade of the conference application.
At the same time, there may be a case where the terminals of some users are installed with the first version of the conference application, and the terminals of some users are installed with the second version of the conference application. When the conference application with the first version and the conference application with the second version are both started to have the whiteboard function in the conference under the same conference number, the whiteboard with different versions uses different servers to perform data communication, so that the compatibility problem is easily caused, and the conference application of the terminal cannot display the user operation condition on other terminals and even directly reports the error to quit the application.
It should be noted that, besides the display device such as the smart tv, the conference application may also be installed on other display devices, such as a computer, a tablet computer, a smart phone, and the like.
In order to solve the problem of compatibility when the whiteboard function is enabled for conference applications of different versions, referring to fig. 2, an embodiment of the present application provides a schematic diagram of a signaling interaction timing sequence in a whiteboard function starting process.
In fig. 2, the first terminal of the whiteboard launch terminal is a terminal used by the whiteboard launcher, and the terminal may be referred to as the first terminal. The conference application on the terminal is a second version, and the whiteboard initiator is one of the conference members of a conference. The first terminal system server is a server on the side of the display equipment and can control the use process of the whiteboard function on each terminal.
In some embodiments, the system server may periodically calculate the version capacity ratio of the active users, for example, calculate the version capacity ratio of the latest active user every other week, wherein the active users may be users who use the whiteboard function for a preset period and the frequency of the use exceeds a corresponding threshold, the version capacity may be determined by a version number, and different version numbers correspond to different version capacities.
In some embodiments, the system server may also determine the version capability duty as the duty of the second version of the total version of whiteboard users.
In some embodiments, since a user initiates a whiteboard and sends an initiation request of a whiteboard function to a system server, which is referred to as an initiation request hereinafter, the user joins in the whiteboard and sends a join request of the whiteboard function to the system server, which is referred to as a join request hereinafter, and the user exits the whiteboard and sends a message of exiting the whiteboard to the system server, the system server may obtain a time for the user initiating the whiteboard to use the whiteboard function application according to a time interval between the initiation request and the message of exiting the whiteboard, obtain a time for the user joining the whiteboard to use the whiteboard function application according to a time interval between the join request and the message of exiting the whiteboard, and obtain a frequency for using the whiteboard function according to the times of the initiation request and the join request.
In some embodiments, the initiation request and the join request sent by the user to the system server carry a version number of the conference application, and the system server may determine, according to the version number, whether the user uses the first version of the conference application or the second version of the conference application. After the system server determines the active users according to the time and frequency of using the whiteboard function, the ratio of the number of the users using the second version to all the active users in the active users can be calculated according to the version number, and the ratio is determined as the version capacity ratio.
To illustrate the whiteboard compatibility effect of different versions of the conference application, the first terminal is taken as an example below to describe the starting process of the whiteboard function.
In some embodiments, as shown in fig. 2, during the running of the conference application, a user of one of the conference members, for example, the first terminal, may click a whiteboard control on the conference interface of the first terminal, and input a control instruction for initiating the whiteboard to the first terminal. The first terminal can generate and send an initiation request to the system server after receiving a control instruction for initiating the whiteboard, wherein the initiation request can include parameters such as a terminal identifier of the first terminal, a version number of a conference application of the first terminal, a conference number of a current conference and the like, the version number can be called a first version parameter when the version number is a first version, the version number can be called a second version parameter when the version number is a second version, and the version number belongs to software version data.
In some embodiments, the whiteboard self-developed by the display device side has only one version, namely the second version, and the whiteboard developed by the third party has only one version, namely the first version, so that the system server can distinguish whether the self-developed whiteboard or the third party whiteboard is installed on the first terminal according to the version numbers. In other embodiments, the whiteboard self-developed by the display device and the whiteboard developed by the third party both have multiple versions, so as to facilitate the server to distinguish whether the whiteboard self-developed by the first terminal is the whiteboard self-developed or the third party whiteboard, the first terminal may further set a whiteboard type parameter in the initiation request, for example, when the value of the whiteboard type parameter is 0, it indicates that the whiteboard currently installed by the first terminal is the third party whiteboard, and when the value of the whiteboard type parameter is 1, it indicates that the whiteboard currently installed by the first terminal is the whiteboard self-developed.
In some embodiments, after receiving an initiation request from a first terminal, a system server may determine, according to that software version data in the initiation request includes a second version parameter, the second version parameter does not include the first version parameter, and the latest calculated version capacity ratio of an active user is greater than a preset threshold, that a whiteboard type to be delivered is a second version, and then returns whiteboard type data to the first terminal, where the whiteboard type data may also be referred to as second whiteboard data and may include whiteboard interface data of the second version, where for example, the preset threshold may be set to 50%.
In some embodiments, if the conference application of the first terminal is the first version, the initiation request of the first terminal only includes the first version parameter, but does not include the second version parameter, or the version capability ratio of the active user calculated by the system server for the last time is less than or equal to the preset threshold, after the system server receives the initiation request of the first terminal, the system server may determine that the whiteboard type to be delivered is the first version, and then return whiteboard type data to the first terminal, where the whiteboard type data may also be referred to as first whiteboard data, and may include whiteboard interface data of the first version.
In some embodiments, the system terminal is configured to control the whiteboard initiating terminal and other participating terminals to interact with each other through the whiteboard of the first version when the conference application of the whiteboard initiating terminal is the first version, at this time, there will be no whiteboard version compatibility problem, and therefore, only the case where the conference application of the whiteboard initiating terminal is the second version will be described below. In some embodiments, after receiving the whiteboard type data, the first terminal may generate a whiteboard interface according to the whiteboard type data, and establish a long connection with the second whiteboard server.
In some embodiments, the system server may further extract a conference number from the initiation request, and then obtain a terminal id of a participating terminal corresponding to the conference number. Illustratively, in addition to the first terminal, the conference terminals corresponding to the conference number may also include other terminals, such as the conference member terminal 1 and the conference member terminal 2, and may also send broadcast messages joining the whiteboard to the conference member terminal 1 and the conference member terminal 2, where the conference member terminal 1 may be referred to as a second terminal and the conference member terminal 2 may be referred to as a third terminal.
In some embodiments, after the first terminal establishes the long connection with the second whiteboard server, the first terminal may further send a message of successful connection to the system server, and the system server may send the broadcast message of joining the whiteboard to the conference member terminal 1 and the conference member terminal 2 according to the message of successful connection.
In some embodiments, after the first terminal establishes a long connection with the second whiteboard server, the whiteboard initiator may perform whiteboard operations such as drawing lines, drawing figures, inserting characters, inserting pictures, zooming, erasing, annotating, and the like on the whiteboard interface, and the first terminal may transmit operation data of the whiteboard initiator to the second whiteboard server in real time, where the operation data may be vector data in a json character string form.
In some embodiments, the process of joining the whiteboard by the second terminal according to the broadcast message of joining the whiteboard may be as shown in fig. 3, and as shown in fig. 3, after receiving the prompt message of joining the whiteboard, the second terminal may generate a join request of the whiteboard function, and send the join request to the system service. The join request may include a terminal identifier of the second terminal, a version number of the conference application of the conference member terminal 1, and a conference number of the current conference, where the terminal identifier may be a terminal ID.
In some embodiments, after receiving the join request from the conference member terminal 1, the system server may search for the whiteboard initiating terminal of the conference number according to the conference number in the join request, that is, the whiteboard type data of the first terminal, so as to determine that the current whiteboard type of the conference number is the second version, determine that the whiteboard type to be issued to the conference member terminal 1 is the second version according to the software version data in the join request including the second version parameter, excluding the first version parameter, and then return the whiteboard type data to the conference member terminal 1, where the whiteboard type data may include the whiteboard interface data of the second version.
In some embodiments, after receiving the whiteboard type data, the conference member terminal 1 may generate a whiteboard interface according to the whiteboard type data, and establish a long connection with the second whiteboard server.
In some embodiments, if the first terminal has sent the operation data to the second whiteboard server before the conference member terminal 1 joins the whiteboard, after the conference member terminal 1 establishes the long connection with the second whiteboard server, the second whiteboard server may be configured to return the existing operation data to the conference member terminal 1, so that the conference member terminal 1 displays the same whiteboard interface as the first terminal according to the received operation data.
In some embodiments, if the first terminal does not send operation data to the second whiteboard server before the conference member terminal 1 joins the whiteboard, after the conference member terminal 1 establishes long connection with the second whiteboard server, the second whiteboard server does not have operation data that can be sent to the conference member terminal 1, the conference member terminal 1 displays a preset whiteboard interface according to the fact that no operation data is received, and at this time, the whiteboard interface of the whiteboard initiating terminal is also the preset whiteboard interface.
In some embodiments, after the conference member terminal 1 joins the whiteboard, the current whiteboard member terminals include the first terminal and the conference member terminal 1. The first terminal and the conference member terminal 1 can perform whiteboard operations such as drawing lines, drawing figures, inserting characters, inserting pictures, zooming, erasing, annotating and the like, if operation data are generated on one terminal, the terminal can update a whiteboard interface according to the operation data and send the operation data to the second whiteboard server in real time, and the second whiteboard server can return the operation data to other whiteboard member terminals so that all the whiteboard member terminals can display the same whiteboard interface.
In some embodiments, after receiving the broadcast message for joining the whiteboard, the conference member terminal 2 may join the whiteboard according to the broadcast message for joining the whiteboard, and the process of joining the whiteboard by the conference member terminal 2 may be as shown in fig. 4.
As shown in fig. 4, after receiving the broadcast message for joining the whiteboard sent by the system server, the conference member terminal 2 may generate a joining request for the whiteboard function, and then send the joining request to the system server. The join request may include the terminal identifier of the conference member terminal 2, the version number of the conference application of the conference member terminal 2, and the conference number of the current conference.
In some embodiments, after receiving the join request from the conference member terminal 2, the system server may search, according to the conference number in the join request, the whiteboard type data sent to the whiteboard initiating terminal of the conference number, thereby determining that the current whiteboard type of the conference number is the second version, determine that the data to be sent to the conference member terminal 2 is the upgrade prompt data according to that the software version data in the join request includes the first version parameter and does not include the second version parameter, and then send the prompt message to the conference member terminal 2 according to the upgrade prompt data. The prompt message can be provided with a link address of a second version installation file of the conference application, and the prompt message is used for representing that the whiteboard version of the third terminal is lower.
In some embodiments, the conference member terminal 2 may display the version upgrade prompt window according to the prompt message after receiving the upgrade prompt message.
In some embodiments, if the conference member 2 wants to reject the upgrade, the rejection control may be clicked on the version upgrade prompting window, and the conference member terminal 2 sends an upgrade rejection message to the system server according to the trigger instruction of the rejection control in the window.
In some embodiments, the system server may send whiteboard type data, which may be referred to as first whiteboard data, which may include a first version of whiteboard interface data, to the conference member terminal 2 after receiving the upgrade rejection message of the conference member terminal 2.
In some embodiments, after receiving the whiteboard type data, the conference member terminal 2 may generate a whiteboard interface according to the whiteboard type data, and establish a long connection with the first whiteboard server.
In some embodiments, the system server may further generate a broadcast message of data version extension after receiving the upgrade rejection message of the conference member terminal 2, and the broadcast message may include a first instruction, and the first instruction may be a data version extension instruction, and the data version extension instruction may include the first version identifier. The first instruction is used for representing that communication connection needs to be established with the first whiteboard server, and starting a data format conversion task, wherein the data format conversion task is configured to convert the operation data on the second version whiteboard into operation data supported by the first version whiteboard.
In some embodiments, the system server may further send a prompt message to the terminals using the second version after receiving the upgrade rejection message for the conference member terminal 2, the content of the prompt message may be configured to account for the type of operation not supported by the conference member terminal 2, and the prompt message may be displayed on the respective terminals after being received using the second version of the terminals.
In some embodiments, after receiving the broadcast message, the whiteboard initiating terminal and the conference member terminal 1 may determine, according to the first version identifier in the data version extension instruction, that the terminal of the first version exists in the whiteboard member, need to establish a long connection with the first whiteboard server, and start a data format conversion task.
In some embodiments, the data format conversion task, upon initiation, may convert the operational data on the respective terminal into a first version of supported vector data, which is then sent to the first whiteboard server.
It should be noted that, because the whiteboard of the first version does not support some whiteboard functions of the second version, part of the operation data of the second version may not be converted into the data of the first version, and each terminal may convert only the operation data of the data type covered by the preset conversion rule into the data supported by the first version.
In some embodiments, the converted data may be set with the operation time of the original operation data before conversion.
In some embodiments, after receiving vector data sent by one whiteboard server, the first whiteboard server may forward the vector data to other whiteboard member terminals. After the first terminal and the conference member terminal 1 receive the vector data, the vector data can be discarded according to the fact that the operation time of the vector data is later than the time of joining the first terminal and the conference member terminal into the whiteboard.
In some embodiments, after the conference member terminal 2 joins the whiteboard, the current whiteboard member terminals include the first terminal, the conference member terminal 1, and the conference member terminal 2. The first terminal and the conference member terminal 1 can perform whiteboard operations such as drawing lines, drawing figures, inserting characters, inserting pictures, zooming, erasing, commenting and the like supported by the second version, and the conference member terminal 2 can perform whiteboard operations such as drawing lines, drawing figures and inserting characters supported by the first version.
In some embodiments, if the whiteboard initiator inputs a user operation on the first terminal, the first terminal may determine whether the user operation is a user operation supported by the first version according to a preset conversion rule, if so, convert the operation data into vector data supported by the first version, then send the vector data to the first whiteboard server, and send the operation data before conversion to the second whiteboard server, and if not, send the operation data only to the second whiteboard server.
In some embodiments, the second whiteboard server may forward the received operation data of the first terminal to the conference member terminal 1, so that the conference member terminal 1 may display the user operation of the whiteboard initiator according to the operation data.
In some embodiments, the first whiteboard server may forward the received operation data of the first terminal to the conference member terminal 1 and the conference member terminal 2, so that the conference member terminal 1 and the conference member terminal 2 may display the user operation of the whiteboard initiator according to the operation data.
In some embodiments, if the conference member 1 inputs a user operation on the conference member terminal 1, the conference member terminal 1 may determine whether the user operation is a user operation supported by the first version according to a preset conversion rule, if so, convert the operation data into vector data supported by the first version, then send the vector data to the first whiteboard server, and send the operation data before conversion to the second whiteboard server, and if not, send the operation data only to the second whiteboard server.
In some embodiments, if the conference member 2 inputs a user operation on the conference member terminal 2, the conference member terminal 2 may transmit the operation data to the first whiteboard server.
In some embodiments, the first whiteboard server may forward the received operation data of the conference member 2 to the first terminal and the conference member terminal 1, so that the first terminal and the conference member terminal 1 may display the user operation of the conference member 2 according to the operation data.
Referring to fig. 5, in some embodiments, during the course of the conference, if the conference member 2 clicks the exit whiteboard control on the whiteboard interface, the conference member terminal 2 may send a message of exiting the whiteboard to the system, where the message may include the terminal identification and the conference number of the conference member 2.
In some embodiments, after receiving the message that the conference member 2 exits the whiteboard, the system server may operate the whiteboard of the first version according to all the member terminals of the current conference, and may generate a broadcast message with a reduced version, where the broadcast message may include a second instruction, and the second instruction may be a data version reduction instruction, and is used to represent that it is necessary to disconnect the communication connection with the first whiteboard server, and end the data format conversion task.
In some embodiments, after receiving the broadcast message, the first terminal and the conference member terminal 1 may respectively disconnect the long connection with the first whiteboard server according to the second instruction, and close the data format conversion task.
In some embodiments, after the data format conversion task is closed, if the first terminal or the conference member terminal 1 generates the operation data, the first terminal or the conference member terminal 1 does not convert the operation data into the operation data of the first version any more, but directly sends the operation data to the whiteboard server, so that the whiteboard server forwards the operation data to other conference member terminals, and the other conference terminals can display the operation data on the whiteboard server.
The above embodiment shows a case where the whiteboard initiated by the first terminal is the whiteboard of the second version, where if the system server determines that the version capacity duty ratio of the active user is less than or equal to the preset threshold value after the first terminal initiates the whiteboard, or the version number of the first terminal is the first version, the whiteboard type data returned to the first terminal is the whiteboard type data corresponding to the whiteboard of the first version, so that the whiteboard initiated by the first terminal is the whiteboard of the first version.
In some embodiments, if the whiteboard initiated by the first terminal is a whiteboard of the first version, no matter which version of whiteboards is supported by the conference member terminal 1 and the conference member terminal 2, when the whiteboard is added, the system server sends the whiteboard type data of the first version to the system server, so that the whiteboard member terminals cooperate with each other through the whiteboard of the first version.
For further explanation on fig. 2 to fig. 5, fig. 6 shows a schematic structural diagram of a whiteboard interaction system according to some embodiments, as shown in fig. 6, a first terminal and a conference member terminal 1 supporting the first version and the second version functions may be provided with a whiteboard version adaptation module, a whiteboard operation data processing module, and a whiteboard message control module, and a conference member terminal 2 supporting only the first version function is provided with a whiteboard operation data processing module and a whiteboard message control module.
In some embodiments, the whiteboard message control module may be communicatively coupled to the system server and may receive data from the system server. For example, in fig. 6, for the first terminal and the conference member terminal 1, whiteboard type data, a data version extended broadcast message, a data version reduced broadcast message, and the like of the system server may be received. For the conference member terminal 2, an upgrade prompt message, whiteboard type data, and the like of the system server may be received.
In some embodiments, the whiteboard operation data processing module may be connected to the second whiteboard server, and may receive operation data input by a user, respond on the whiteboard interface according to the operation data input by the user, send the operation data to the second whiteboard server, receive operation data of another terminal sent by the second whiteboard server, and respond on the whiteboard interface according to the operation data of the another terminal.
In some embodiments, the whiteboard version adapting module may be connected to the first whiteboard server, may convert operation data input by a user on the terminal into operation data of a first version, send the operation data of the first version to the first whiteboard server, receive operation data of the first version of another terminal sent by the first whiteboard server, convert operation data of the first version of another terminal into operation data of a second version, and then respond on the whiteboard interface according to the operation data of the second version obtained by the conversion.
