[0027] Embodiment 1

[0028] Figure 1A flowchart of a real-time playback method for a network conference is provided for the first embodiment of the present application. The embodiment of the present application is applicable to the case of real-time playback of a network conference. The method can be executed by a real-time playback device for a network conference. The real-time playback device for a network conference can be implemented in the form of hardware and / or software. The real-time playback device for a network conference can be configured in an electronic device with data processing capabilities. Figure 1 As shown, the method includes:

[0029] S110: If a playback request for the current network conference is received, the playback source of the current network conference is switched from the real-time audio and video code stream of the current network conference to the stored audio and video data.

[0030] The current network conference may be a conference attended by multiple participants, and the current network conference may be a video conference, an audio conference, etc. The stored audio and video data is the audio and video data stored during the current network conference.

[0031] In an embodiment of the present application, a feasible solution is: during an online conference, if it is detected that a user clicks a real-time playback button, it is determined that a playback request for the current online conference is received. In this case, the current terminal is displaying the real-time audio and video content of the current online conference, that is, the playback source is the real-time audio and video stream of the current online conference, and the playback source is switched to the stored audio and video data, for example, to the audio and video files in the storage space.

[0032] Specifically, the technical solution of the embodiment of the present application can be executed during the current online conference. During the current online conference, after receiving the real-time audio and video stream, on the one hand, the real-time audio and video stream is decoded and displayed, and on the other hand, the audio and video stream is stored. In this case, if the user is affected (for example, the user drinks water, is interrupted by a colleague, or receives a phone call, etc.), the user can initiate a playback request. Since the audio and video data of the current online conference has been stored, the playback source can be switched to the stored audio and video data for real-time playback of the current online conference.

[0033] S120, playing the stored audio and video data at the set playback speed.

[0034] The playback speed may be set based on actual conditions, and the present application embodiment does not limit this. For example, the playback speed may be set to be greater than 1.

[0035] Specifically, the stored audio and video data is playback content, so its playback speed can be set by the user. If the playback speed is greater than 1, as time goes by, the playback progress of the stored audio and video data will catch up with the real-time progress of the current network conference.

[0036] In one feasible solution, the set playback speed input by the user is obtained, and the stored audio and video data is played based on the set playback speed. If a progress adjustment operation triggered by the user is detected (for example, forward 10 seconds, backward 10 seconds, etc.), it is determined whether the progress adjustment of the stored audio and video data based on the adjustment progress in the progress adjustment operation exceeds the progress range of the stored audio and video data. If not, the audio and video data with the adjusted progress is played.

[0037] S130: If it is determined that the playback progress of the stored audio and video data is synchronized with the real-time progress of the current network conference, the playback source of the current network conference is switched to the real-time audio and video code stream of the current network conference.

[0038] Specifically, if the playback speed is greater than 1, then as time goes by, the playback progress of the stored audio and video data will gradually approach the real-time progress of the current online conference. If it is determined that the playback progress of the stored audio and video data is synchronized with the real-time progress of the current online conference, the playback source of the current online conference will be switched to the real-time audio and video stream of the current online conference. At this time, since the playback source is switched after the playback progress of the stored audio and video data is synchronized with the real-time progress of the current online conference, it will not affect the current participants' experience.

[0039] The technical solution of the embodiment of the present application can be used to display the previous meeting content (stored audio and video data) again and smoothly switch back to the real-time content of the current online conference if the current participants are affected and miss part of the conference content during the current online conference.

[0040] The technical solution of the embodiment of the present application includes: if a playback request for the current network conference is received, the playback source of the current network conference is switched from the real-time audio and video code stream of the current network conference to the stored audio and video data; the stored audio and video data is the audio and video data stored during the current network conference; the stored audio and video data is played at a set playback speed; if it is determined that the playback progress of the stored audio and video data is synchronized with the real-time progress of the current network conference, the playback source of the current network conference is switched to the real-time audio and video code stream of the current network conference. This technical solution enables users to watch the previous meeting content again by switching the playback source to the stored audio and video data, and when the playback progress of the stored audio and video data is synchronized with the real-time progress of the current network conference, the playback source is switched back to the real-time audio and video code stream, thereby achieving the effect of coherently displaying the previous meeting content and the subsequent real-time meeting, and improving the meeting experience of the meeting participants.

[0041] Embodiment 2

[0042] Figure 2This is a flow chart of a real-time playback method for a network conference provided in Example 2 of the present application. The embodiment of the present application is optimized based on the above embodiment.

[0043] like Figure 2 As shown, the method of the embodiment of the present application specifically includes the following steps:

[0044] S210: If a playback request for the current network conference is received, determine a playback time according to the playback request.

[0045] Specifically, the playback request may be initiated by the current participant after missing part of the conference content. The current participant may select a playback time and then initiate the playback request. In this case, the playback time may be directly extracted from the playback request.

[0046] In an embodiment of the present application, optionally, before receiving a playback request for the current network conference, the method further includes: if it is determined that the conference leave control has been triggered; recording the triggering time of the conference leave control; accordingly, determining the playback time according to the playback request includes: determining the triggering time of the conference leave control in the playback request as the playback time.

[0047] Specifically, during the current online conference, a conference leave control is set. If the current participant needs to leave or is interrupted by the outside world, he or she can click on the conference leave control. If it is detected that the conference leave control has been triggered, the trigger time of the conference leave control is recorded, and the current online conference continues to be displayed in real time until the user clicks on the playback control, at which time a playback request including the trigger time of the conference leave control is generated.

[0048] This solution is configured in this way so that when the audio and video are subsequently played back, the playback can be accurately started from the content that the current participant has not paid attention to, thereby improving the user experience of the current participant.

[0049] In an embodiment of the present application, optionally, during the current network conference, the method also includes: cyclically storing the continuously received real-time audio and video streams of the current network conference into a storage space; performing cyclic aging processing on the audio and video data in the storage space whose storage time is within a target storage time period; the time in the target storage time period is earlier than the time in the remaining time periods; accordingly, switching the playback source of the current network conference from the real-time audio and video stream of the current network conference to the stored audio and video data, including: switching the playback source of the current network conference from the real-time audio and video stream of the current network conference to the audio and video data in the storage space.

[0050] Specifically, during the current online conference, on the one hand, the real-time audio and video code stream needs to be decoded and played, and on the other hand, the real-time audio and video code stream needs to be stored in a loop so that relevant content can be retained when playback is required. When the real-time audio and video code stream is stored in a loop, a storage space can be pre-allocated, and the latest audio and video content of the first preset duration can be stored in the storage space in a loop. The first preset duration can be determined according to actual conditions. For example, the first preset duration can be 30 seconds. In order to ensure that the latest audio and video are always stored in the storage space, the audio and video data in the storage space whose storage time is in the target storage time period can be subjected to a loop aging process. The target storage time period is the oldest time period. For example, if 35 seconds of audio and video data are stored in the storage space, and the corresponding storage time is from 8:01 to 8:01:35, then 8:01 to 8:01:05 can be the target storage time period (this time can be the standard time of a certain time zone).

[0051] Exemplarily, a portion of storage space is reserved on the current network conference terminal (e.g., a video conference terminal). When the terminal joins the conference, the terminal receives the audio and video code stream from the remote end, one direction is normal audio and video output, and the other direction is sent to the storage module. The storage module will always cyclically store the audio and video data of the first preset duration (configurable), and these stored audio and video data will cyclically age the data of the second preset duration (configurable) at the front according to the standard time of a certain time zone, so as to ensure that the audio and video data of the first preset duration is always stored on the terminal. Among them, the first preset duration can be 30 seconds, and the second preset duration can be 5 seconds.

[0052] This solution is configured in such a way that the storage space can always store the latest audio and video data of the first preset duration, so that the current participants can initiate conference playback at any time.

[0053] S220, switching the playback source of the current network conference from the real-time audio and video code stream of the current network conference to the stored audio and video data.

[0054] The stored audio and video data are audio and video data stored during the current network conference.

[0055] S230, playing the stored audio and video data at a set playback speed starting from the playback time.

[0056] Specifically, in a feasible solution, the duration of the stored audio and video data is the first duration. If the playback time is earlier than the earliest time of the stored audio and video data, the stored audio and video data is played from the beginning; otherwise, the stored audio and video data is played from the playback time.

[0057] This solution is set up in this way, taking into account both the effect of conference playback and taking up less storage space, greatly improving the user experience.

[0058] S240: If it is determined that the playback progress of the stored audio and video data is synchronized with the real-time progress of the current network conference, the playback source of the current network conference is switched to the real-time audio and video code stream of the current network conference.

[0059] In an embodiment of the present application, optionally, the process of determining whether the playback progress of the stored audio and video data is synchronized with the real-time progress of the current network conference includes: if the difference between the playback progress of the stored audio and video data and the real-time progress of the current network conference is less than a preset time threshold, then determining that the playback progress of the stored audio and video data is synchronized with the real-time progress of the current network conference.

[0060] Among them, the preset time threshold can be determined according to actual conditions, and the embodiment of the present application does not limit this. For example, it can be 0.1 seconds.

[0061] Specifically, if the difference between the playback progress of the stored audio and video data and the real-time progress of the current online conference is less than the preset time threshold, it means that the playback progress of the stored audio and video data is close to the real-time progress of the current online conference, and the switch can be made without affecting the current participants' experience.

[0062] In an embodiment of the present application, optionally, the set playback speed is greater than 1; accordingly, the process of determining whether the playback progress of the stored audio and video data is synchronized with the real-time progress of the current network conference includes: determining the progress synchronization time according to the playback time, the current time and the set playback speed; wherein the progress synchronization time is the time when the playback progress of the stored audio and video data is synchronized with the real-time progress of the current network conference.

[0063] In the embodiment of the present application, optionally, the progress synchronization time is determined according to the following formula:

[0064]

[0065] Among them, T2 is the progress synchronization time, T0 is the playback time, T1 is the current time, and X0 is the set playback speed.

[0066] Specifically, when playing the stored audio and video data, the progress synchronization time of the stored audio and video data and the current network conference can be calculated, and the playback source can be accurately switched at the progress synchronization time.

[0067] It should be noted that the embodiment of the present application plays the current network conference on the one hand, and stores the real-time audio and video code stream on the other hand to obtain the stored audio and video data. During the playback of the stored audio and video data, the real-time audio and video code stream can still be stored in the background, so that as time goes by, the progress of the stored audio and video data can also increase, thereby providing support for the switching of the playback source. For example: the playback speed is 2x, and the duration of the looped stored audio and video data is 30 seconds. If 30 seconds of the stored audio and video data are played, the real-time progress of the current network conference is already after 15 seconds, and the latest 15 seconds of audio and video content are also stored in the storage space, so the stored audio and video data can still be played until the two progresses are synchronized and the playback source of the current network conference is switched to the real-time audio and video code stream of the current network conference.

[0068] The technical solution of the embodiment of the present application can replay the current online conference at any time by cyclically storing the audio and video code streams of the current online conference, and because of the cyclic storage method, it does not take up too much storage space. After the playback progress of the stored audio and video data is synchronized with the real-time progress of the current online conference, the technical solution switches the playback source, so that there will be no sudden changes in the picture during the entire switching process, achieving a seamless switching effect, so that the current participants can learn about the missed meeting content and communicate with other participants in real time, greatly improving the user experience of the participants.
