Fig. 1 is a flowchart of a presentation control method according to an embodiment of the present invention, which includes the following steps.

S101, control information from the terminal equipment is received.

Wherein the terminal device may be a portable device. For example, the terminal device may be a cell phone, tablet, smart watch, wearable device, or the like. The portable characteristic of the terminal equipment provides convenience for the user to control the demonstration manuscript and facilitates the user to control the demonstration manuscript.

The control information is information for controlling the presentation, and the control information may be a control instruction or a key value. The control information is not limited to the above two types, and may be other types of information, which is not limited herein.

The control of the presentation can be a plurality of controls of next page, previous page, ending and the like, each control can be used as an operation item, each operation item corresponds to one type of control information, that is, the operation items and the control information are in one-to-one correspondence, and the correspondence between the operation items and the control information is preset.

Illustratively, the control information is a key value, and the operation items are in one-to-one correspondence with the key value. When the operation item is the previous page, the corresponding key value is as follows: keyevent _ DPAD _ UP or keyevent _ DPAD _ LEFT. When the operation item is the next page, the corresponding key value is: keyevent key _ DPAD _ DOWN or keyevent key _ DPAD _ RIGHT, when the operation item is finished, the corresponding key value is: keyevent. When the user performs an ending operation on the terminal device, the key value sent by the terminal device is keyevent.

Wherein the control information is sent by the terminal device through the access control webpage. The control web page is used for controlling the next page, the previous page, the end and the like of the presentation displayed by the display device, and the operation items included in the control web page can be set in a self-defined mode. For example, there are three operation items in the control web page, which are: next page, previous page and end, it is possible for the user to perform the operation of next page, previous page or end on the control web page when accessing the control web page using the terminal device.

The control web page may be generated by pre-written code, and the code for generating the control web page is stored in a device providing a web service for the control web page.

Wherein the device providing the web service for the control web page may be a display device. Before the display device provides the Web service, the display device is provided with an application program for providing the Web service, a background Web service can be started by using the application program, and the display device can be used as a service end for providing the Web service based on the background Web service.

The device providing the web service for controlling the web page may also be a web server, which is a third party device other than the display device and the terminal device. The web server provides web services for the control web page, and the web server is in communication connection with the display device.

The display device receives control information from the terminal device, and in one implementation mode, after the terminal device obtains the control information corresponding to an operation item based on the selected operation item in the control webpage, the terminal device sends the control information to the web server. The web server then forwards the control information from the terminal device to the display device.

In one embodiment, after the display device is started, before the step of receiving the control information from the terminal device is executed, the display device may perform self-test to detect whether the display device is connected to the network. If the display equipment is not connected with the network, prompting a network error; if the display device is connected to a network, other operations may be performed.

And S102, controlling the displayed presentation according to the control information.

And controlling the operation item corresponding to the control information on the presentation based on the corresponding relation between the control information and the operation item. For example, if the control item corresponding to the control information is the previous page, the page turning control of the previous page is performed on the presentation.

The device for opening the presentation in the embodiment of the present invention may be a display device, or may be another device. The control modes of the presentation may be different depending on the device that opens the presentation. Opening the presentation refers to opening the presentation by using an application program in the device. For example, an application program of Microsoft Office PowerPoint is installed in the device, and the PPT file is stored locally in the device, and the device opening the PPT file means that the application program Microsoft Office PowerPoint opens the PPT file. The following description will be made separately for the case where the presentation is opened by different devices.

In one embodiment, the display device is connected to a remote desktop of a remote device, which may be a desktop computer, a notebook, a tablet, or the like. Through the remote desktop connection, the remote device can project the content displayed by the remote device to the display device. The presentation is stored in the remote device and opened by the remote device such that the presentation is displayed on the remote device, the presentation also being displayed on the display device based on the remote desktop connection.

After receiving the control information from the terminal equipment, the display equipment sends the control information to the remote equipment through remote desktop connection. And after receiving the control information, the remote equipment controls the presentation correspondingly to the control information.

For example, the control information received by the display device from the terminal device is a key value of keyevent key _ DPAD _ UP, and the display device transmits the key value to the remote device through the remote desktop connection. After receiving the key value of keyevent key _ DPAD _ UP, the remote device performs control of the previous page on the presentation.

Through this embodiment, under the great inconvenient copy of the file of presentation, perhaps under the inconvenient circumstances of carrying of desktop computer, can directly regard as the remote equipment with the equipment that stores the presentation, be connected with the long-range desktop of display device, directly throw the screen with the presentation that the remote equipment was opened on the display device. Thus, convenience is provided for displaying the presentation on the display device.

In another embodiment, the presentation is opened and displayed by the display device. In one implementation, the presentation is stored locally on the display device, and the display device has an application that can open the presentation. The corresponding application program in the display device opens the presentation and displays the opened presentation.

For example, an application program of Microsoft Office PowerPoint is installed in the display device, and the PPT file is stored locally in the display device. The display device opens and displays the PPT file stored locally by using Microsoft Office PowerPoint.

In this case, the control of page turning, ending, playing, and the like of the presentation is performed by the display device. In one implementation manner, a control server APK (android package) is pre-stored locally in a display device, and functions implemented by the control server APK may be set by a programmer in a self-defined manner. The control web page is built in the control server APK. For the display device, the demonstration file is controlled by the installed control server APK.

Through the embodiment, when the file of the presentation is small, the file can be copied to the display device to be stored locally, and the file can be opened and displayed by the display device, so that the operation is simplified, and the efficiency of opening and displaying the presentation is improved. Especially, under the condition that a plurality of demonstration manuscripts need to be opened in sequence, the demonstration manuscripts can be stored in the display equipment locally, and opening operation is directly carried out on the display equipment, so that other complicated operations are avoided, and the efficiency of opening and displaying the demonstration manuscripts is improved.

In one embodiment, in order to facilitate the terminal device to obtain a URL (Uniform resource locator) address of the control webpage, the control webpage can be accessed more conveniently. The display device may generate the graphic identification code from the URL address of the control web page and display the graphic identification code.

The pattern recognition code may be any one of a one-dimensional code, a two-dimensional code, and the like. The terminal device can acquire information such as a URL address contained in the image identification code through the image identification code. In one implementation, the terminal device scans the image identification code to obtain information contained in the image identification code. For example, the terminal device scans the two-dimensional code by scanning in the WeChat to acquire information in the two-dimensional code.

The display device displays the pattern recognition code at least in two ways. In the first display mode, the pattern recognition code is directly displayed at a preset position in a display area of the display device, and the preset position can be set by a user. For example, the preset position may be a lower right corner of the area displayed by the display device, and the graphical identification code is directly set at the lower right corner for display. In the first display mode, the display equipment directly displays the graphical identification code, and the graphical identification code can be displayed to a user more intuitively in the display mode, so that the user can conveniently scan the graphical identification code by using the terminal equipment.

In the second display mode, the display equipment is provided with a suspension key, and the suspension key and the pattern identification code form a corresponding relation. And when the suspension key is triggered, displaying the graphic identification code corresponding to the suspension key. For example, the floating key is displayed on the display device, the floating key corresponds to a two-dimensional code, and when the display device detects that the floating key is triggered, the display device displays the two-dimensional code.

In the second display mode, the area occupied by the suspension key is smaller than that of the pattern identification code, so that the suspension key has small shielding influence on other displayed contents on the display device, and even can not shield other displayed contents. When the suspension key is set to be in a semitransparent state, other displayed contents cannot be shielded. When the presentation is displayed on the display device, the reading experience of the user on the presentation is improved.

The display device displays the pattern recognition code in two ways, which are not limited to the above two ways, and may also include other display ways.

The display device displays the graphical identification code, which can be scanned by the terminal device for the user. And the terminal equipment acquires the URL address included in the graphic identification code and accesses the control webpage corresponding to the URL address. Through the implementation mode provided by the embodiment of the invention, the terminal equipment can acquire the URL address of the control webpage only by scanning the graphic identification code, and directly skips to access the control webpage represented by the URL address after acquiring the URL address, so that the convenience of accessing the control webpage by the terminal equipment is improved.

In one embodiment, the step of generating the graphic identification code from the URL address of the control webpage may include the following steps.

And synthesizing the address of the equipment for providing the web service for the control webpage and the suffix identification of the control webpage to obtain the URL address of the control webpage.

The suffix identification of the control webpage can be set by a user. For example, the address of the search web page is: www.aaa.com/cn/search, wherein search is identified by a suffix of the search page.

The device for providing the web service for the control web page may be a display device or a web server. And when the equipment providing the web service is display equipment, synthesizing the address of the display equipment and the suffix identification of the control webpage to obtain the URL address of the control webpage. And when the equipment providing the web service is a web server, synthesizing the address of the web server and the suffix identification of the control webpage to obtain the URL address of the control webpage. The web server can be an Ali cloud server, a Tencent cloud server and the like.

For example, the address of the display device is www.aaa.com, the address of the web server is www.bbb.com, the web server provides a web service for the control web page, the suffix of the control web page is identified as control, and the URL address obtained by combining the address of the web server and the suffix of the control web page is: www.bbb.com/control. The control webpage can be accessed through the URL address.

After the URL address of the control webpage is obtained, a pattern identification code is generated from the obtained URL address, namely the generated pattern identification code comprises the URL address of the control webpage.

The types of IP addresses to which the URL addresses belong are different, and the networks used by the terminal device to access the control web page indicated by the URL addresses may be different. The types of the IP addresses comprise public network IP addresses and local network IP addresses. In order to facilitate the terminal device to access the control webpage represented by the URL address by using a proper network after acquiring the URL address. In one embodiment, the step of generating the graphic identification code from the URL address of the control webpage may include the following steps.

And judging whether the URL address of the control webpage is a public network IP address or not. For example, it is generally considered that an IP address with a 10-start header is a local area network IP address, i.e., IP addresses from 10.0.0.0 to 10.255.255.255 are local area network IP addresses. When the URL address of the control web page is 10.168.0.125, it may be determined that the URL address is a local area network IP address.

When the URL address of the control web page is determined to be a public network IP address, the URL address may be marked as a URL address having a first identifier, and a graphical identification code may be generated from the URL address having the first identifier.

The URL address having the first identifier indicates that the URL address is a public network IP address. When the URL address acquired by the terminal device from the graphical identification code has the first identifier, the terminal device can access the control webpage represented by the URL address by using the network which can access the external network.

When the URL address of the control web page is determined not to be the public network IP address, that is, the URL address is determined to be the local area network IP address, and for the terminal device, the wireless local area network is required to be used when accessing the URL address, and the wireless local area network used is the wireless local area network connected to the display device.

On the basis that the URL address of the control webpage is the local area network IP address, whether the display equipment is connected with the wireless local area network currently is judged, if the display equipment is connected with the wireless local area network currently, the URL address can be marked as the URL address with the second identification, the URL address with the second identification is used for generating a graphic identification code, and the identification of the wireless local area network is prompted.

The URL address with the second identifier indicates that the URL address is a local area network IP address, and accessing the URL address requires utilizing a wireless local area network to which the display device is currently connected. When the URL address acquired by the terminal equipment from the graphic identification code has the second identifier, the identifier of the wireless local area network can be acquired according to the prompt of the display equipment, and the terminal equipment is connected with the wireless local area network represented by the identifier and accesses the control webpage represented by the URL address with the second identifier by using the wireless local area network.

On the basis that the URL address of the control webpage is the IP address of the local area network, if the display device is judged not to be connected with the wireless local area network currently, the display device starts the WiFi hotspot, marks the URL address as the URL address with the third identification, generates a graphic identification code for the URL address with the third identification, and prompts the identification of the WiFi hotspot.

The URL address with the third identification represents that the URL address is a local area network IP address, and accessing the URL address requires a WiFi hotspot started by using a display device. When the URL address acquired by the terminal device from the graphic identification code has the third identifier, the identifier of the WiFi hotspot can be acquired according to the prompt of the display device, and the terminal device is connected with the WiFi hotspot represented by the identifier and accesses the control webpage represented by the URL address having the third identifier by using the WiFi hotspot.

Through the implementation mode provided by the embodiment of the invention, the display equipment marks the URL address of the control webpage to distinguish the public network IP address from the local network IP address, for the terminal equipment, the IP address type of the URL address can be conveniently distinguished after the URL address is obtained, and further, the control webpage represented by the URL address can be accessed by selecting a proper network according to the IP address type of the URL address.

Corresponding to the above embodiment of the presentation control method applied to the display device, an embodiment of the present invention further provides a presentation control method applied to the terminal device, and as shown in fig. 2, the presentation control method includes the following steps.

S201, accessing a control webpage.

The control webpage is used for controlling the demonstration manuscript displayed by the display equipment, and the terminal equipment controls the demonstration manuscript by accessing the control webpage.

In one embodiment of the terminal device accessing the control webpage, a user can directly input a URL address of the control webpage in a browser of the terminal device, and the browser directly skips to the control webpage, thereby realizing the access of the terminal device to the control webpage.

In another embodiment, the display device displays a graphical identifier that contains the URL address of the control web page. And the terminal equipment acquires the URL address of the control webpage through the graphic identification code.

In one implementation, the terminal device scans the image identifier to obtain the URL address of the control web page included in the image identifier. For example, the graphic identification code displayed by the display device is a two-dimensional code, and the two-dimensional code contains the URL address of the control web page: www.bbb.com/control, when the terminal device scans the two-dimensional code, the terminal device can obtain the URL address www.bbb.com/control of the control web page.

After acquiring the URL address of the control webpage, the terminal device accesses the control webpage represented by the URL address. In one implementation, a terminal device starts a browser, and the started browser obtains a URL address and directly jumps to a control web page indicated by the URL address.

S202, based on the selected operation item in the control webpage, determining the control information corresponding to the operation item.

The control web page may include a plurality of operation items, each of which is a control of the presentation. Illustratively, the operation item "next page" indicates that the presentation is turned backward, for example, the current page of the presentation is page 10, and when the control of next page is performed on the presentation, the presentation is controlled to be turned backward, and at this time, the current page of the presentation is page 11. The operation item "previous page" indicates that the presentation is turned forward by one page, for example, the current page of the presentation is page 5, and when the control of previous page is performed on the presentation, the presentation is controlled to be turned forward by one page, and at this time, the current page of the presentation is page 4. The operation item "end" indicates that the play of the currently displayed presentation is ended. The operation item "play" indicates to play the currently displayed presentation, as shown in fig. 3-1, which is a display interface on the terminal device for controlling the web page, and the played operation item is displayed on the display interface.

The number and types of operation items included in the control web page may be custom set. For example, the control web page includes three operation items, which are respectively: and if the next page, the previous page and the end are finished, when the terminal equipment accesses the control webpage, the previous page, the next page and the end of the presentation are controlled. As shown in fig. 3-2, the display interface for controlling the web page on the terminal device includes three operation items, namely, a next page, a previous page and an end.

After the terminal device accesses the control webpage, each operation item in the control webpage is to be selected for the user. When the terminal device detects that a certain operation item is triggered, namely the operation item is selected, the control information corresponding to the operation item is generated. Wherein, the corresponding relation between the operation item and the control information is preset.

S203, sending the control information to the display device.

The manner in which the control information is transmitted to the display device may vary depending on the device that provides the web service for the control web page. The device providing the web service for controlling the web page may be a display device or may be a web server. The following is a description of the two cases.

In the first case, the device providing web services for controlling web pages is a display device. And the terminal equipment accesses the control webpage of the web service provided by the display equipment, and then the terminal equipment is in communication connection with the display equipment. And the terminal equipment directly sends the control information to the display equipment.

In the second case, the device providing web services for controlling web pages is a web server. And when the terminal equipment accesses the control webpage, the terminal equipment is in communication connection with the web server. And after the control information is generated by the terminal equipment, the control information is sent to the web server, and after the control information is received by the web server, the control information is forwarded to the display equipment.

And after receiving the control information, the display device can control the displayed presentation according to the control information. In one implementation, the presentation is opened by the display device, and the display device directly controls the displayed presentation according to the control information.
