Step 102, determining attribute information of each shared content in the one or more shared contents.
The attribute information may include at least one of a content type of the shared content, content uploader information, content upload time, and a content size. For example, the pdf file corresponds to a content type of "document", and the jpg file corresponds to a content type of "picture". The content uploader information may include, but is not limited to, the name, job title, etc. of the content uploader. The content upload time may refer to a time when the shared content starts to be uploaded to the server, or may refer to a time when the shared content is completely uploaded to the server, which is not limited herein. For real-time shared content (shared content that is not predetermined and changes with actual time, such as shared content like local live-cast data stream), the content upload time may be determined according to the time when the shared content starts to upload to the server. The content size may refer to the size of the memory of the cloud space occupied by the shared content.
Step 103, determining the partition number of the display partition in the shared content display area of the conference desktop to be pushed of the cloud conference and determining the arrangement order of the one or more shared contents in the display partition in the shared content display area according to the attribute information of the one or more shared contents.
The conference desktop is used for displaying the shared content uploaded to the cloud space of the cloud conference.
The shared content display area comprises at least one display partition, and a single display partition is used for displaying at least one shared content. The preset size may be determined according to the size of the conference desktop, and the preset position may be determined according to the display mode of the conference desktop, which is not limited herein. The display modes of the conference desktop include a horizontal screen mode, a vertical screen mode, a grid mode, a full screen mode, a control mode and the like, which are not limited herein, and the display modes supported by different devices are different. For example, when the device is a smartphone, the display modes supported by the device include a horizontal screen mode, a vertical screen mode, a grid mode, a full screen mode, a control mode, and the like. When the device is a large-screen device or a projection device, the display modes supported by the device include a grid mode, a full-screen mode and the like. When the equipment is an intelligent computer, the display modes supported by the equipment comprise a horizontal screen mode, a vertical screen mode, a grid mode, a full screen mode, a control mode and the like.
For example, referring to fig. 1C and fig. 1D, when the conference desktop is displayed in the large-screen device, the conference exit component is disposed at the top end of the shared content display area, where the display mode of the large-screen device in fig. 1C is a grid mode, and the display mode of the large-screen device in fig. 1D is a full-screen mode. In a large screen device, the location of the shared content display area in full screen mode and grid mode may be the same. The size of the shared content display area may include a display height and a display width, the display height of the shared content display area may be equal to or slightly lower than the display height of the conference desktop, and the display width of the shared content display area may be equal to or smaller than the display width of the conference desktop. In the grid mode shown in fig. 1C, any one display sub-area may be selected by clicking, double-clicking, or the like, and the display sub-area is displayed in full screen. As shown in fig. 1D, in the full-screen mode, the shared content display area of the conference desktop only displays one display partition (which may be any display partition, and fig. 1D takes the full-screen display partition a as an example), and at this time, the size of the shared content display area is consistent with the size of the display partition a.
For another example, referring to fig. 1E to fig. 1H, when the conference table is displayed in the smart phone, functional device display areas are disposed at the top end and the bottom end of the shared content display area, and the functional device display areas may include the following functional devices: the conference management system comprises a control authority operation component, a conference exit component, a shared content uploading component, a display mode switching component, a start/stop sharing component, a conference member invitation component, a conference member viewing component, a screen projection component, a microphone component, a loudspeaker component, a conference duration component and the like, which are not limited herein. For the shared content uploading component, a plurality of different types of shared content may be uploaded by using the same component, or different types of shared content may be uploaded by different sub-components, for example, the shared content uploading component may include a plurality of sub-components such as "file", "picture", "website", "video", and the like, which is not limited herein. In addition, the individual function component may also be disposed in the shared content display area, such as a grid mode switching component and a full-screen mode switching component, and the like, may be disposed in the upper right corner of the display partition of the shared content display area, or in other positions.
In fig. 1E to 1H, the display mode indicated in fig. 1E is a full-screen mode when the screen is vertical, the display mode indicated in fig. 1F is a checkered mode when the screen is vertical, the display mode indicated in fig. 1G is a full-screen mode when the screen is horizontal, and the display mode indicated in fig. 1H is a checkered mode when the screen is horizontal. In the smart phone, the positions of the shared content display area in the full screen mode and the grid mode during vertical screen display can be the same, and the shared content display area is positioned on the upper side of a conference desktop; the positions of the shared content display area in the full screen mode and the grid mode during the horizontal screen mode can be the same, and the shared content display area is located in the middle of the conference desktop. The size of the shared content display area may include a display height and a display width, in the vertical screen mode, the display height of the shared content display area is smaller than the display height of the conference desktop, and the display width of the shared content display area may be equal to or smaller than the display width of the conference desktop; in the landscape mode, the display height of the shared content display area may be equal to or less than the display height of the conference desktop, and the display width of the shared content display area may be equal to or less than the display width of the conference desktop.
For another example, when the conference table is displayed in the smart computer, the display mode is similar to the mode in which the smart phone is installed in a horizontal screen, and details are not repeated here.
It should be noted that the functional setting of the functional components and the display positions of the functional components in the functional component display area may be set by the developer or the meeting staff, fig. 1C to 1H only show some possible examples, and the scope of protection of the present application is not limited to the examples shown in fig. 1C to 1H.
And step 104, updating the page content of the conference desktop to be pushed according to the number of the partitions and the arrangement sequence.
Step 105, pushing the conference desktop to at least one of the plurality of local devices and the conference device.
In specific implementation, when a participant uploads new shared content or when the control right attribution of the conference desktop changes, the page content of the conference desktop may change accordingly, which is not limited herein. When the content of the page of the conference desktop changes, the server may push the updated conference desktop to at least one of the plurality of local devices and the conference device.
It can be seen that, in the embodiment of the present application, a server may receive one or more shared contents uploaded by at least one local device, determine attribute information of each shared content in the one or more shared contents, determine, according to the attribute information of the one or more shared contents, the number of partitions of a display partition in a shared content display area of a conference desktop to be pushed for a cloud conference, determine an arrangement order of the one or more shared contents in the display partition in the shared content display area, update page contents of the conference desktop to be pushed according to the number of partitions and the arrangement order, and push the conference desktop to at least one local device and a conference device in a plurality of local devices; therefore, the number of the display partitions and the arrangement sequence of the shared contents are determined according to the attribute information of the one or more shared contents, and the one or more shared contents are displayed in order on the conference desktop, so that the efficiency of searching files in the cloud conference process is improved, the file sharing efficiency is further improved, the user experience is optimized, and compared with the scheme that the conference desktop is created and updated on the server and pushed to the local equipment and the conference equipment when the local equipment runs, the configuration requirement on the local equipment is lower (the local equipment only needs to receive the conference desktop pushed by the server, and the data processing amount is smaller), so that the application range is wider.
In one possible example, the determining of the partition number of the display partition in the shared content display area of the conference desktop to be pushed in the cloud conference may include the following steps:
and step 1031, determining the type number of the content types.
Step 1032, if the number of the types is single, determining the number of the partitions to be single.
Step 1033, if the number of types is less than or equal to a preset number threshold, determining that the number of partitions is the same as the number of types.
Step 1034, if the number of types is greater than the preset number threshold, determining that the number of partitions is the same as the preset number threshold.
Wherein the content type comprises at least one of document, audio, picture, video and local real-time screen projection data stream. The content type may also include cad files, vsdx files, and the like, without limitation. Shared content of the same content type is presented in the same display partition.
The documents may include txt, doc, docx, ppt, pptx, pdf, and other types of documents, and the above multiple types of documents may be regarded as shared content of the same content type (because they belong to the same content type of "document"), or may be regarded as shared content of different content types, which is not limited herein.
The local real-time screen projection data stream may be a real-time screen projection data stream of any local device, for example, a screen projection of a smart phone, a screen projection of a smart computer, a screen projection of a smart watch, and the like, which is not limited herein. The data stream may be a full-screen data stream of the local device, or a split-screen data stream, which is not limited herein; the screen projection may be performed on an original screen or a mirror image, and is not limited herein.
For example, referring to fig. 1C, the shared content in the display partition a may be a real-time screen-shot data stream shared by multiple smartphones, or a pdf document shared by multiple local devices, or other shared content of the same content type, which is not limited herein.
The preset number threshold may be set by a developer or a conference participant, and is not limited herein, and may be, for example, 2, 3, 4, 5, 6, and the like. It is understood that the number of partitions of the display partition in the conference desktop must not exceed a preset number threshold. The display size of each display section may be the same or different.
In specific implementation, when the shared content uploaded by the local device is of the same type, the number of display partitions in the shared content display area of the conference desktop is 1, and the size of the display partitions may be the same as the size of the shared content area.
And under the condition that the number of the types of the shared content is less than or equal to a preset number threshold, the number of the partitions of the display partition is the same as the number of the types, and the display partition is completely displayed in the shared content display area. The display size of each display partition may be automatically adjusted according to the number of the shared content in the display partition, the size of the shared content display area, and other factors, or may be manually adjusted by the user, which is not limited herein.
Under the condition that the number M of the types of the shared content is larger than the preset number threshold N, only the display partitions with the arrangement order of N are displayed in the conference desktop because the number of the partitions of the display partitions in the conference desktop does not exceed the preset number threshold N. The display size of each display partition may be automatically adjusted according to the number of the shared content in the display partition, the size of the shared content display area, and other factors, or may be manually adjusted by the user, which is not limited herein.
It can be seen that, in the embodiment of the present application, a server may determine a number of types of the content type, determine the number of partitions as a single number if the number of types is a single number, determine that the number of partitions is the same as the number of types if the number of types is less than or equal to a preset number threshold, and determine that the number of partitions is the same as the preset number threshold if the number of types is greater than the preset number threshold; therefore, the number of the display partitions displayed in the shared content display area is limited, so that the display of more display partitions in the conference desktop is ensured, each display partition is displayed in a more appropriate display size, and the user experience is optimized.
In one possible example, if the number of types is greater than the preset number threshold, the method may further include the following steps:
step 10341, generate an augmented desktop.
Wherein the above-mentioned supplementary desktop is used for presenting a display partition not shown at the conference desktop.
In a specific implementation, as described above, in a case that the number M of the types of the shared content is greater than the preset number threshold N, since the number of the partitions of the display partition in the conference desktop does not exceed the preset number threshold N, only the display partition with the first N arrangement order is displayed in the conference desktop, and at this time, the server may generate an augmented desktop, where the augmented desktop is used to display the (N + 1) -mth display partition. Therefore, the display partitions, not shown, of the conference desktop are displayed through the supplementary desktop, and the supplementary desktop is combined with the conference desktop, so that all the display partitions can be displayed in order, and the user experience is optimized.
It should be noted that, the display partitions of the add-on desktop can also preset corresponding thresholds to limit the number of partitions in one desktop, and at this time, if one add-on desktop cannot display all of the (N + 1) -th display partitions, a plurality of add-on desktops can be generated until all of the M display partitions are displayed.
In one possible example, the method may further comprise the steps of:
step 10342, determining the control right attribution of the conference desktop.
The control right attribution is used for representing the conference participants who acquire the control right of the conference desktop in the cloud conference process, and the conference participants who acquire the control right of the conference desktop are target conference participants.
Step 10343, pushing the augmented desktop to at least one of the plurality of local devices and the conference device in response to a desktop operation instruction of a target local device.
The target local device refers to a local device corresponding to the target participant, and the desktop operation instruction is used for representing the control of the target participant on the conference desktop.
In specific implementation, a target participant can control a conference desktop through a target local device, for example, the target local device performs operations such as sliding up, sliding down, sliding left and sliding right on the conference desktop, the target local device sends a corresponding desktop operation instruction to a server, and the server responds to the desktop operation instruction, pushes an additional desktop to at least one local device and the conference device, and the additional desktop is displayed in a display area corresponding to the conference desktop.
It can be seen that, in the embodiment of the present application, the server may determine the control right attribution of the conference desktop, and push the augmented desktop to at least one local device of the plurality of local devices and the conference device in response to the desktop operation instruction of the target local device, thereby facilitating the control of the target conference participant on the shared content of the display partition in the augmented desktop.
In one possible example, the method may further comprise the steps of:
step 10344, determine the control right attribution of the conference desktop.
The control right affiliation is used for representing the conference participants who acquire the control right of the conference desktop in the cloud conference process, and the conference participants who acquire the control right of the conference desktop are target conference participants.
Step 10345, determining if target shared content is present in the conference desktop and/or the supplemental desktop.
The target shared content refers to shared content uploaded to a cloud space by target participants.
Step 10346, determining a target display partition if target shared content is present in the conference desktop and/or the supplemental desktop.
The target display partition refers to a display partition where the target shared content is located.
And step 10347, amplifying the target display partition according to a preset proportion.
The preset ratio may be set by a developer or a participant, or may be set by a default of the server, which is not limited herein.
In the specific implementation, the fact that the sharing content uploaded by the user is usually demonstrated by the user is considered, so that when the conference participants acquire the control right of the conference desktop and become target conference participants, the sharing content uploaded by the target conference participants in the conference desktop and/or the supplementary desktop is determined, and the display subareas where the uploaded sharing content is located are amplified, so that the target conference participants can demonstrate the uploaded sharing content, other conference participants can watch the demonstration of the target conference participants, and the user experience is optimized.
Further, when the target participant corresponding to the control right attribution changes, for example, if the first target participant changes from zhang san to lie xi, the display partition corresponding to the shared content uploaded by zhang san is restored to the initial size, and the display partition corresponding to the shared content uploaded by lie xi is amplified according to the preset proportion.
In addition, if the conference desktop and the supplementary desktop do not have target shared content, that is, no target display partition exists, no amplification operation is required.
It can be seen that, in the embodiment of the application, the server may determine the control right attribution of the conference desktop, determine whether the target shared content exists in the conference desktop and/or the supplementary desktop, determine the target display partition if the target shared content exists in the conference desktop and/or the supplementary desktop, and amplify the target display partition according to a preset proportion; therefore, the target meeting staff can demonstrate the uploaded shared content, other meeting staff can watch the demonstration of the target meeting staff, and user experience is optimized.
In one possible example, the determining of the arrangement order of the one or more shared contents in the display section of the shared content display area may include:
step 1035, determining a first weight corresponding to the content uploader information, a second weight corresponding to the content uploading time, and a third weight corresponding to the content size.
Step 1036, performing weighted calculation on the content upload person information, the content upload time, and the content size according to the first weight, the second weight, and the third weight, respectively, to obtain the arrangement value of each shared content.
Step 1037, determining the arrangement order according to the arrangement value.
The content uploader information may include a name, a job rank, and the like of the content uploader, which is not limited herein.
The first, second, and third weights may be set as default values by research and development personnel, or may be set by conference participants according to conference requirements, and are not limited herein. The first, second and third weights may be set to the same weight or may be set to different weights, but are not limited thereto, for example, the first weight a1Set to 0.3, a second weight a2Set to 0.1, third weight a3Set to 0.05.
For example, when a cloud conference is held at a certain department of a company, the participant determines that the role level of Zhang III is 1, the role level of Li IV is 2, and the higher the number corresponding to the role level is, the higher the role level is. When the meeting participants do not input the content uploader information, the job ranks corresponding to all the content uploaders may be defaulted to 1.
The unit of the content uploading time may be minutes, seconds, hours, and the like, which is not limited herein.
The calculation unit of the content size may be KB, MB, GB, or the like, and is not limited herein. For a shared file with a difficult-to-determine content size, such as a local live-cast data stream, the corresponding content size may be set to 1 MB. It can be understood that, since the same type of shared content is displayed in the same display partition, when the size of the content of all the local real-time screen casting data streams in the display partition of the local real-time screen casting data streams is 1MB, the arrangement order of the local real-time screen casting data streams can still be determined through the content upload information and the content upload time.
The arrangement value of the shared content may be determined by the following formula: x = P a1+T*a2+R*a3. Wherein, x is the arrangement value corresponding to the shared content, a1Is a first weight, a2Is a second weight, a3P is content uploader information, T is content upload time, and R is content size.
For example, if zhang san (job level 1) uploads a doc file with the size of 2M when the meeting time is 00:30 (0.5 minute), and li ye san (job level 2) uploads a doc file with the size of 7k when the meeting time is 01:30 (1.5 minute), the arrangement value of shared content uploaded by zhang san is x1=1 × 0.3+0.5 × 0.1+2 × 0.05=0.45, and the arrangement value of the shared content uploaded by lee four is x2=2*0.3+1.5*0.1+(7/1024)*0.05=0.75。x1<x2Then the file uploaded by lie four is arranged before the file uploaded by zhang three.
It is to be understood that, in the above example, in the case where the other attribute information is the same, the later the content upload time is, the larger the arrangement value of the shared content is, the further the arrangement order thereof is. The conference participants may also change the mechanism of the arrangement order by changing the second weight, which is not limited herein.
In addition, the arrangement order of the display partitions may be adjusted by the target participants, or may be determined according to the number of the shared content in each display partition, which is not limited herein. For the display partitions with the same number of shared contents, the arrangement order may be determined according to file uploading time (the file may be arranged before the uploader, or arranged before the uploader), file size, and other factors.
For example, 8 shared contents are uploaded in a certain cloud conference, wherein 3 pdf files, 2 doc files, 1 local real-time screen projection data stream and 2 audio files exist. If the pdf file and the doc file are divided into the same content type, the display partition of the document class includes 5 shared contents, the display partition of the local real-time screen projection data stream includes 1 shared content, the display partition of the audio class includes 2 shared contents, the display partition of the document class is arranged on the left side or the upper side of the display partition of the audio class, and the display partition of the audio class is arranged on the left side or the upper side of the display partition of the local real-time screen projection data stream. If the pdf file and the doc file are divided into different content types, the display partition of the pdf file comprises 3 shared contents, the display partition of the doc file comprises 2 shared contents, the display partition of the local real-time screen casting data stream comprises 1 shared content, the display partition of the audio file comprises 2 shared contents, the display partition of the pdf file is located on the leftmost side or the uppermost side of the shared content display partition, and after the display partition of the doc file and the display partition of the audio file determine that the display partition of the local real-time screen casting data stream is determined according to the file uploading time, the display partition of the local real-time screen casting data stream is located on the rightmost side or the lowermost side of the shared content display partition.
It can be seen that, in the embodiment of the present application, the server may determine a first weight corresponding to the content uploader information, a second weight corresponding to the content upload time, and a third weight corresponding to the content size, perform weighted calculation on the content uploader information, the content upload time, and the content size according to the first weight, the second weight, and the third weight, respectively, to obtain a configuration value of each shared content, and determine the configuration order according to the configuration value; therefore, shared contents uploaded by the participants are orderly arranged, the participants can conveniently and efficiently find files quickly, the conference efficiency is improved, and the user experience is optimized.
In one possible example, the updating the page content of the conference desktop to be pushed may include the following steps:
step 1041, determining whether the currently processed shared content is a real-time shared content.
The real-time shared content refers to content which is not predetermined and changes along with the change of actual time.
Step 1042, if the currently processed shared content is a non-real-time shared content, sending preview request information to the at least one local device.
The preview request information is used for requesting the conference participants to input a preview picture of the non-real-time shared content.
Step 1043, receiving the preview confirmation information sent by the at least one local device.
The preview confirmation information is used for representing the preview picture determined by the conference participants.
And step 1044 of determining a preview screen of the non-real-time shared content according to the preview confirmation information.
And 1045, updating the page content of the conference desktop to be pushed according to the preview picture.
In a specific implementation, for shared content displayed in a conference desktop, a server may determine whether each shared content is real-time shared content, and if the shared content is non-real-time shared content, the server may send preview request information to at least one local device to request participants to determine a preview picture of the non-real-time shared content, determine the preview picture according to preview confirmation information sent by the local device, and display the preview picture at a position corresponding to the shared content in a display partition.
Therefore, the efficiency of searching shared content by participants is improved, the conference efficiency is improved, and the user experience is optimized.
Further, after the third member of the conference participants determines the preview picture of a certain shared content, if the fourth member of the conference participants wants to change the preview picture of the shared content, the server can update the corresponding page content of the conference desktop according to the preview picture determined by the fourth member of the conference participants, and send corresponding prompt information to the third member of the conference participants to inform the third member of that the preview picture of the shared content has been changed by the fourth member of the conference participants.
In addition, the page content in the supplementary desktop can also be updated as described above, and will not be described herein again.
It can be seen that, in the embodiment of the present application, the server may determine whether the currently processed shared content is a real-time shared content, and if the currently processed shared content is a non-real-time shared content, send preview request information to at least one local device, receive preview confirmation information sent by the at least one local device, determine a preview picture of the non-real-time shared content according to the preview confirmation information, and update the page content of the conference desktop to be pushed according to the preview picture; therefore, the conference participants can confirm the preview picture of the shared content displayed in the display partition of the conference desktop through requesting, the efficiency of searching the shared content by the conference participants is improved, the conference efficiency is improved, and the user experience is optimized.
Corresponding to the embodiment shown in fig. 1B, please refer to fig. 2, fig. 2 is a schematic flowchart of a screen projection display method provided in the embodiment of the present application, and the method is applied to a local device, where the local device is connected to a server, and the screen projection display method includes:
step 201, uploading one or more shared contents to the server.
The shared content refers to information uploaded to a cloud space of the cloud conference by conference participants of the cloud conference through first local equipment, the cloud conference refers to a conference group created in the cloud space by a conference creator through second local equipment, and the cloud space refers to a resource space used by a cloud end for operating and storing data of the cloud conference.
Step 202, receiving the conference desktop pushed by the server.
