The memory 320 may mainly include a program storage area and a data storage area, wherein the program storage area may store an operating system, an application program (such as a sound playing function, an image playing function, etc.) required by at least one function, a boot loader (boot loader), and the like; the storage data area may store data (such as audio data, a phonebook, etc.) created according to the use of the terminal device, and the like. Further, the memory 320 may include high speed random access memory, and may also include non-volatile memory, such as at least one magnetic disk storage device, flash memory device, or other volatile solid state storage device. It is understood that, in the embodiment of the present application, the memory 320 stores a program for the bluetooth device to connect back.

The input unit 330 may be used to receive input numeric or character information and generate key signal inputs related to user settings and function control of the terminal device. Specifically, the input unit 330 may include a touch panel 331 and other input devices 332. The touch panel 331, also referred to as a touch screen, can collect touch operations of a user (e.g., operations of the user on the touch panel 331 or near the touch panel 331 using any suitable object or accessory such as a finger, a stylus, etc.) on or near the touch panel 331, and drive the corresponding connection device according to a preset program.

Alternatively, the touch panel 331 may include two parts, a touch detection device and a touch controller. The touch detection device detects the touch direction of a user, detects a signal brought by touch operation and transmits the signal to the touch controller; the touch controller receives touch information from the touch sensing device, converts the touch information into touch point coordinates, sends the touch point coordinates to the processor 380, and can receive and execute commands sent by the processor 380.

WiFi belongs to short-distance wireless transmission technology, and the terminal equipment can help users to send and receive e-mails, browse webpages, access streaming media and the like through the WiFi module 370, and provides wireless broadband internet access for the users. Although fig. 3 shows the WiFi module 370, it is understood that it does not belong to the essential constitution of the terminal device, and may be omitted entirely as needed within the scope not changing the essence of the invention.

The processor 380 is a control center of the terminal device, connects various parts of the whole terminal device by using various interfaces and lines, and performs various functions of the terminal device and processes data by running or executing software programs or modules stored in the memory 320 and calling data stored in the memory 320, thereby performing overall monitoring of the terminal device. Optionally, processor 380 may include one or more processing units; preferably, the processor 380 may integrate an application processor, which primarily handles operating systems, user interfaces, applications, etc., and a modem processor, which primarily handles wireless communications.

The bluetooth module 3100 may be Bluetooth Low Energy (BLE), or a module according to actual needs. It can be understood that, in the case that the terminal device in the embodiment of the present application is a user terminal and a service tool, the terminal device includes a bluetooth module. It is to be understood that the bluetooth module does not belong to the essential constitution of the terminal device and may be omitted entirely as needed within the scope not changing the essence of the invention, for example, the bluetooth module may not be included in the server.

Although not shown, the terminal device may further include a camera. Optionally, the position of the camera on the terminal device may be front-located, rear-located, or built-in (the camera body may be extended when in use), which is not limited in this embodiment of the present application.

Video conferencing is a multimedia communication technology that enables people in different places to achieve real-time, visual and interactive functions through a certain transmission medium. The video conference can distribute various information such as static or dynamic images, voice, characters or pictures of people to terminal equipment of each user through various communication transmission media, so that geographically dispersed users can exchange information in various modes such as graphics and sound, the understanding capability of multiple parties on contents is improved, and the conference is just like a conference in the same meeting place.

Illustratively, when the device for implementing the video conference is a large screen, the large screen is rich in functions, and not only audio and video transmission but also auxiliary video transmission can be implemented through a dual video streaming technology (i.e., an h.239 protocol). In general, a main video transmits a character image video, an auxiliary video transmits content to be shared, and a plurality of large screens can realize a plurality of auxiliary video functions, namely, a plurality of parties are allowed to simultaneously transmit the auxiliary videos in the same video conference. In addition, the terminal types of large-screen calling are rich, and besides other large screens, the terminal types can also call network communication tools such as mobile phones, pads and instant messaging (Skype).

In a video conference, a large screen or the like terminal device may not be able to present the content of the video conference to the user for some reason. For example, reasons include: the user leaves the terminal equipment, the connection between the terminal equipment and the server is disconnected, and the like. This may result in the user missing the videoconference content.

In view of this, an embodiment of the present application provides a control method in a video conference, where when a user returns to a terminal device or a connection between the terminal device and a server is restored, the server may push conference content of the video conference to the terminal device during a period in which the user leaves or during a period in which the connection is disconnected, so as to facilitate the user to obtain the conference content, and improve quality of the video conference.

Fig. 4 is a schematic flowchart of a control method in a video conference according to an embodiment of the present application, and as shown in fig. 4, the method includes: the video conference begins.

S401, the system monitors the multi-access condition.

In the embodiment of the application, the system may be software for implementing a video conference, and the system may be run in a terminal device and a server. The terminal equipment can access the video conference through the system and acquire the relevant information of the corresponding video conference in the server through the system. The related information may include: audio and video information of the video conference, information of conference participants and the like.

In this embodiment, a terminal device running the system may be referred to as a client, and a server running the system may be referred to as a server.

It can be understood that the system monitoring the multiple access condition refers to the server monitoring the access condition of the client, and may also be understood as the server monitoring the access condition of the terminal device. The access situation may include: whether the connection between the terminal equipment and the server is disconnected or not, whether a user is detected in front of a screen of the terminal equipment or not and the like.

In a possible implementation manner, when the system monitors an important event, the system determines that a conference starts, starts a complete recording function, and monitors a multi-access situation in real time. The important event may be the arrival of a scheduled time for the conference, or the detection of sound in a video conference, or the presence of video content in a video conference, etc.

In a possible implementation, the system monitors the multiple access condition from the beginning of the videoconference until the end of the videoconference.

S402, the system monitors whether a certain path enters an abnormal state or not.

In the embodiment of the present application, the abnormal state includes: poor network quality, late user leave and access to the conference, etc. The poor network quality refers to the situation that in the video conference communication process, normal video communication cannot be guaranteed due to network signal delay, jitter, network packet loss, communication abnormity and the like, or the conference effect is poor due to other situations.

User away refers to when the user is not in front of the screen or the user is unable to participate in the video conference. In a possible implementation manner, when the system monitors a preset behavior through a camera in the terminal device or an external camera, it is determined that the user leaves. The preset behavior includes, but is not limited to, the user leaving the screen and the user taking off the headset.

The access meeting time is later than the meeting starting time. In a possible implementation manner, the video conference includes a conference list, and when the video conference starts, a user in the conference list does not access the conference, and the system determines that the path enters an abnormal state. In a possible implementation manner two, the video conference does not include a conference list, the system compares the access time of a certain road with the start time, and if the access time is later than the start time, the system records that the access time of the road is in a normal state, and the access time is not in an abnormal state before. If the access time is earlier than or equal to the start time, the path is in a normal state.

And S403, the system acquires the abnormal state code and the Tnot, and marks the abnormal state code and the Tnot (X path, state Snot and occurrence time Tnot).

The abnormal state code in the embodiment of the application is used for indicating the state of the client, such as normal, poor network, user leaving and the like.

In a possible implementation, different abnormal state codes correspond to different abnormal state scenes. Illustratively, the status identifier of the client in the system is denoted by S. The state of the client may be represented by a different state code. Specifically, S plus =1 represents a normal state of the client, S minus =2 represents an abnormal state of the client, S difference =4 represents a network difference of the client, S away =8 represents a user departure of the client, and the like. S good or S return may also indicate the client normal state.

Therefore, the system can accurately process different abnormal scenes according to different abnormal codes.

Illustratively, the time stamp of the client in the system is denoted by T. Specifically, tfirt represents the time when the client changes to the abnormal state, ttefor represents the time when the client changes to the normal state, and tfirt or ttefor may also represent the time when the client changes to the normal state. T-ion represents the time the client left the state.

In the embodiment of the application, [ X way, state S non, occurrence time T non ] indicates identification information of a system to a client in a non-normal state, X way, state S non, time of changing into the non-normal state is T non.

In a possible implementation manner, when the duration of the abnormal state exceeds a first threshold, the system acquires the abnormal state code and the tney. The first threshold may be in units of seconds, milliseconds, minutes, etc., and, for example, the first threshold may be 3S. The first threshold is not specifically limited in the embodiment of the present application. Therefore, the misjudgment that the client enters the abnormal state can be avoided.

S404, according to the abnormal state code, correspondingly limiting the client side in the path, and broadcasting the state of the client side to other paths for displaying and reminding.

In this embodiment, S404 is an optional step, and the terminal device may not execute S404.

It can be understood that the system can control the client in the abnormal state according to the state code, for example, limit the sound pickup device to continue sound pickup, avoid the non-conference sound from entering the device, and further improve the experience effect of the user of the client in the normal state. In a possible implementation manner, when the system monitors that a user in a certain path leaves, the system limits screen display and/or sound playing of the client in the path. Therefore, the leakage of the conference content of the video conference during the leaving of the user can be avoided, and the security of the conference is improved.

It will be appreciated that the abnormal status code is broadcast to other way display alerts, such as: a pop-up message "XXX left", a list of participants showing the corresponding status identification, etc. Therefore, other ways can know that the way is in the abnormal state and can not communicate and interact with the user at the abnormal state client.

S405, the system monitors that the X path is recovered to a normal state, and records time T positive.

In a possible implementation manner, when the duration of the normal state exceeds the second threshold, the system determines that the X path is restored to the normal state. The second threshold may be in units of seconds, milliseconds, minutes, etc., and, for example, the second threshold may be 3S. The first threshold is not specifically limited in the embodiment of the present application.

In a possible implementation manner, when the abnormal state of a certain path is that the user leaves, the system may monitor that the user and/or the user wears an earphone and the like through a camera of the terminal device to determine that the user returns, and then confirm that the path is restored to the normal state.

In a possible implementation manner, when the abnormal state of a certain path is a network difference, and the system monitors that the network of the path meets the requirements of the video conference, the system confirms that the path is recovered to the normal state.

S406, the system pushes [ TNOT, TNOT ] recording content to the X path, the limitation of the X path is removed, and the state of the content is broadcasted to the reminding removal of other paths.

Correspondingly, when the terminal device does not execute S404, S406 pushes [ TNOT, T is positive ] recording content to X path for the system.

It will be appreciated that the system pushes the recorded content for the period of the abnormal state to the client and removes the reminder that its state is broadcast to other ways. In this way, the user can obtain the missing conference content by viewing the recorded content. And the users of other paths can also acquire the state of the X path according to the state broadcast. The status broadcast may be a display of a reminder at an interface of the client.

It should be noted that the start time of recording the content may be a time when the client enters the abnormal state, or may be a time when the client enters the abnormal state within a certain range. The time within a certain range may be in seconds or milliseconds. The stop time of recording the content may be the time when the client enters the normal state, or the time when the client enters the normal state within a certain range.

In the embodiment of the application, the system can acquire the recorded content through the recording screen, and also can acquire the recorded content in the memory of the server in a copying manner.

In the embodiment of the application, two methods for extracting the recorded content are provided, and one method is to intercept a complete video according to time points in different paths. Illustratively, in the complete video from the beginning of the conference to the end of the conference, the extraction is based on [ Tnot, Tpositive ] time nodes. Another method is that when a certain path enters an abnormal state, the system starts recording at T, and stops recording at T regular time. Illustratively, when the client a and the client B enter the abnormal state, the system records the video conference during the abnormal state of the client a and the abnormal state of the client B, and pushes the recorded content.

In the embodiment of the application, the display modes of the recorded content in the client interface are various. In a possible implementation manner, the recorded content may be displayed on the interface in a picture-in-picture manner, or displayed in a split screen manner occupying a certain area in a floating window manner. Illustratively, the client defaults to a picture-in-picture widget playing the recorded content. The client can also switch the picture-in-picture to a large window to play and record the content, and the small window broadcasts the video conference in a live mode.

It is understood that the client may enter the abnormal state many times, and the system may push the recorded content in the following two ways.

In a possible implementation manner, when a certain path of client enters an abnormal state and returns to a normal state for many times, the system pushes a plurality of recorded contents to the client, and a client interface may display a list of the plurality of recorded contents, so that a user can conveniently select and obtain corresponding contents.

In a second possible implementation manner, when a certain path of client enters an abnormal state for multiple times, and the time of the abnormal state is long, or the time interval between several adjacent abnormal states is short, the system may push the complete recorded content of the client during several adjacent abnormal states to push the complete recorded content. For example, if the client is in an abnormal state at 13:00-13:05 and 13:06-13:08, the system may push 13:00-13:08 of the recorded content to the client.

And S407, controlling the recorded content of [ T NOT, T NOT ] by the X path.

In the embodiment of the present application, [ tno, tnt ] is used to indicate a time interval from tno to tnt, for example: 13:00-13:10.

In the embodiment of the present application, the functions for controlling the recording of the content may include pause, play, fast forward, double speed, and the like. Therefore, the user can conveniently select the proper time to play the conference content in different modes.

In a possible implementation manner, when a conference is finished, a certain path is in an abnormal state, and at a finishing interface of a client of the path, the system pushes recorded content from the path entering the abnormal state to the end of the conference.

In a possible implementation manner, when the conference is finished, the system pushes the complete conference recording content to a plurality of clients and prompts whether to store the content. Therefore, the user can conveniently acquire the conference content through the conference recording after the conference is finished.

The video conference is ended.

In summary, the control method in the video conference provided by the embodiment of the present application is applied to a system, the system monitors the state of the client, records the time when the client enters the abnormal state and marks the state code of the client when the client enters the abnormal state, and the system displays and/or restricts the sound of the client according to the state code of the client, thereby avoiding the leakage of the conference content and increasing the security of the conference. The system informs other clients in the conference of the abnormal client state. When the system monitors that the client side recovers the normal state, the system pushes the conference recording content of the client side in the abnormal state, so that a user can acquire the missing conference content of the client side in the abnormal state in the conference process, the integrity of the video conference process is ensured, the quality of the video conference is improved, and the user experience is improved.

The following describes a control method in the video conference shown in fig. 4 with reference to fig. 5 to 13.

Illustratively, fig. 5 is a timing diagram of a video conference provided in an embodiment of the present application. As shown in fig. 5, the video conference includes 3 clients, which are client a, client B, and client C. Client a, client B, and client C correspond to user 1, user 2, and user 3, respectively.

At time T0, the video conference begins. At time T1, the system monitors the network difference of the client a, marks the state of the client a as S difference, and records T off-time as T1. And the system synchronizes the state information to the normal state client. The state information sent by the system to client B and client C is "client a is diff".

At time T2, the system monitors that user 2 of client B leaves the screen, marks the status of client B as S-away, and records T-away as T2. And controlling the client B in an abnormal state by the system because the state of the client B is S-away. The control means includes, but is not limited to, limiting the display of client B and/or setting the microphone of client B to mute. The system synchronization status information is sent to the client C in the normal state, "client a is S bad, and client B is S away".

At time T3, the system monitors that the network quality of client a is getting better, and the requirements of the video conference are met. The system marks the status of client a as S good and records the time T good as T3. The system sends the recorded content of T1-T3 to client a. And the system synchronizes the state information to the normal state client. The normal clients are client C and client A. The state information sent by the system to the client C is "client a is S good, client B is S away", and the state information sent by the system to the client a is "client B is S away".

In a possible implementation manner, the client does not receive the trigger operation of the user 1, and the client plays the recorded content of T1-T3 in a picture-in-picture mode after 3 s.

At time T4, the system detects user 2 of client B coming back, marks the status of client B as Checko, and records Tworkback as T4. The system sends the recorded content of T2-T4 to client B. And the system synchronizes the state information to the normal state client. The normal clients are client C and client A. The state information sent by the system to client C and client a is "client B is S times".

In a possible implementation manner, the client receives a trigger operation that the user 2 suspends the watching of the recorded content, and suspends the recorded content of T2-T4.

At time T5, the system monitors the network difference of the client a, marks the state of the client a as S difference, and records T off-time as T5. The system synchronizes state information to the client B and the client C, and the state information is that the client A is S poor.

At time T6, the system monitors that the network quality of client a is getting better, and the requirements of the video conference are met. The system marks the status of client a as S good and records the time T good as T6. The system sends the recorded content of T5-T6 to client a. And the system synchronizes the state information to the normal state client. The normal clients are client A, client B and client C. The state information sent by the system to client B and client C is "client a is S good".

At time T7, the conference ends and the system pushes the recorded content of T0-T7 to client a, client B and client C.

The display interface of the terminal device is explained below with reference to fig. 6 to 13. For the same or similar interfaces, the embodiments of the present application are not described in detail. Illustratively, terminal a corresponds to client a, terminal B corresponds to client B, and terminal C corresponds to client C.

Fig. 6 is a schematic view of a video conference interface provided in an embodiment of the present application. Illustratively, fig. 6 shows the interface display of the terminal at time T0. Fig. 6 includes: a user avatar 601, a participant list 602, and settings 603. The user avatar 601 may display an avatar of the user device, or may display the user and the user environment photographed by each terminal device. Participant list 602 is used to display participant information, such as names of participants. The participant list can be hidden after the terminal device receives the user operation, and the display content of the participant list are not limited in the embodiment of the application. Settings 603 may include one or more of: mute, speaker, video, share, chat, more, away, or other types of settings.

The display interface of the terminal a in the video conference will be described with reference to fig. 7 to 10.

It is understood that the recorded content may be displayed in a variety of ways. The display interfaces of fig. 7 and 8 correspond to two display modes of the recorded content respectively.

When the recorded content is displayed in the interface in the form of a floating window, the display interface of terminal a at time T3 may be as shown in fig. 7. Fig. 7 includes: current video conference content 701, participant list 702, recorded content 703, and settings 704. The current video conference content 701, the participant list 702 and the setting item 704 may refer to the above interface description, and are not described herein again. The recorded content 703 may be displayed in the form of a floating window in any area of the interface, and the display position of the recorded content 703 is not limited in this embodiment.

The recorded content 703 includes a tab bar 705, a recorded content display window 706, a progress bar 707, and a recorded content setting item 708. The label column 705 includes a recording content name, which may be a system recording time or any other name, and this is not limited in this embodiment of the present application. The recorded content display window 706 is used for displaying the conference content recorded by the system when the client a is in an abnormal state. The progress bar 707 is used to adjust the conference content displayed in the recorded content display window 706. The recording content settings 708 may include one or more of: pause, play, speed, volume, selection, previous, next, or other type of recorded content setting.

Illustratively, when the terminal device receives a trigger operation of clicking pause by a user, the terminal device stops playing the recorded content. And when the terminal equipment receives the trigger operation of clicking playing by the user, the terminal equipment plays the recorded content. When the terminal equipment receives the trigger operation of clicking the double speed by the user, the speed of the terminal equipment when the recorded content is played is changed. And when the terminal equipment receives the triggering operation of clicking the volume by the user, the volume is increased when the terminal equipment plays the recorded content. The terminal equipment provides various playing modes, and can meet diversified playing requirements of users.

When the recorded content is displayed in the interface in a picture-in-picture manner, the display interface of terminal a at time T3 may be as shown in fig. 8. Fig. 8 includes: current video conference content 801 and recorded content 802. The current video conference content 801 is displayed full screen and the recorded content 802 is displayed in a picture-in-picture over the area of the current video conference content 801. The current video conference content 801 and the recorded content 802 may be played simultaneously. The terminal equipment pushes the recorded content in the video conference interface, so that a user can conveniently acquire missed video conference content during the video conference.

It will be appreciated that the client may be in the abnormal state many times. The display interface of the terminal equipment also comprises a recording content list. Exemplarily, taking a display interface of a terminal a at time T6 as an example, fig. 9 is a schematic display interface of the terminal a according to an embodiment of the present application. As shown in fig. 9, the interface further includes a recording content list 901 on the basis of fig. 7. The user can select the recorded content in the abnormal state period through the recorded content list. The terminal equipment displays the recording content list, so that a user can select missed video conference content conveniently according to the recording content list.

In a possible implementation manner, the recorded content list includes identifiers of recorded content, and when the terminal device receives a trigger operation on any identifier in the recorded content list, the terminal device displays the recorded content corresponding to any identifier. The identifier of the recorded content may be a start-stop time corresponding to the recorded content, or may be other types of identifiers. The embodiment of the present application does not limit the identifier of the recorded content.

In a possible implementation manner, when the client enters the abnormal state for many times, the system may push the complete recorded content or continuously record content segments during the abnormal state. Therefore, the number of recorded contents pushed by the terminal equipment is reduced, and users can be prevented from missing video conference contents. Moreover, the recorded content is continuous, so that the user can conveniently obtain the conference information, and the conference quality is improved.

In a possible implementation manner, when the system determines that the number of times that the client enters the abnormal state is greater than the number threshold, the server sends the complete recorded content of the video conference to the terminal device.

In a possible implementation manner two, when the system determines that the ratio of the abnormal state duration to the normal state total duration is greater than the ratio threshold, the system sends the complete recording content of the video conference to the terminal device.

In a possible implementation manner, when the system determines that the time interval duration of the multiple adjacent abnormal states of the terminal device is less than the interval threshold, the server sends the continuously recorded content segments to the terminal device. The continuous recording content segment is the corresponding complete recording content when the terminal equipment is in the abnormal state for a plurality of times. Illustratively, taking the above-mentioned event in fig. 5 as an example, when the time of T3-T5 is short, the system pushes the recorded content of T1-T6 to the client a at time T6. As shown in fig. 10, the recording content name 1002 of the recording content 1001 in fig. 10 is T1-T6.

The display interface of terminal B will be described with reference to fig. 11.

When the system detects that the user 2 of the terminal B leaves the screen, the system controls the terminal B. For example, taking the time T2 as an example, the system monitors that the user 2 of the terminal B leaves the screen, and fig. 11 is a schematic view of a display interface of the terminal B according to an embodiment of the present application. As shown in fig. 11, the microphone identification 1101 is in a mute state in the interface, and the video conference content is not displayed in the interface. The mute of the microphone of the terminal equipment can avoid the noise of the abnormal terminal equipment from being transmitted into the video conference, and reduce the interference of the video conference.

In a possible implementation, when the system detects that the user 2 of the terminal B leaves the screen, the system controls the terminal B to turn off the screen or sleep. Therefore, the leakage of the video conference content during the leaving of the user can be avoided, and the safety of the video conference is improved.

The display interface of the terminal C will be described with reference to fig. 12.

The system synchronously sends the abnormal state information to the normal state client, and a reminding notice and/or a state identification may be generated in the interface of the normal state client. Therefore, communication between the user of the normal client and the user of the abnormal client can be reduced.

For example, when the system monitors that the network of the client a is poor, the display interface of the terminal C may be as shown in fig. 12. The interface includes a reminder notification 1201 and a status identification 1202. The reminder 1201 displays "client a network is bad", and so on. The embodiment of the present application does not limit the specific content of the reminding notification.

In a possible implementation, the reminder notification disappears after a preset time, or is continuously displayed. The preset time may be in units of seconds or minutes, which is not limited in the embodiment of the present application.

At the end of a video conference, the system may push the recorded content during the conference to multiple clients. Illustratively, as shown in fig. 13, a bullet box 1301 is included in fig. 13. And displaying that the conference is finished and whether the recorded content is saved or not in a bullet frame. When the system receives a trigger operation of selecting 'yes' by the user, the system saves the recorded content during the meeting to a default address or prompts the user to select a saving path. When the system receives a trigger operation of selecting 'no' by the user, the system discards the recorded content during the conference and exits the video conference. Therefore, after the video conference, the user can obtain the video conference content through the recording content pushed by the terminal equipment.
