Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In addition, technical solutions between various embodiments may be combined with each other, but must be realized by a person skilled in the art, and when the technical solutions are contradictory or cannot be realized, such a combination should not be considered to exist, and is not within the protection scope of the present invention.
As shown in fig. 1, the present application provides a video conference packet interaction method, which guarantees stability of video conference packet interaction and meets user requirements.
For packet-interactive video conferencing, the goals of low latency, high quality, and low network load need to be achieved. For a one-to-many videoconference, the delay is not significant since there is no reference. However, in the case of many-to-many packets, it is easy for one party to speak and the other party to receive the other party and respond again after a long time, and the delay is more noticeable when there are a plurality of speaking objects. The high quality refers to the high video quality of the video conference, and the video quality of the video conference of the interactive video is generally actively reduced in order to pursue low delay, so that the phenomena of blurred pictures and frame skipping are caused, and the video conference is not facilitated to be developed. The low network load means that the network load is low, and the network load is reduced under the condition of meeting the requirements of two or more paths of videos and the quality and quantity of the videos.
Therefore, the video conference system with the layered architecture is adopted in the video conference, and the video conference system is automatically adjusted to meet the requirements of the video conference when a grouping interactive mode is needed. The conference system is provided with a plurality of servers, and corresponding services are provided by the corresponding servers when conference interaction is carried out. Specifically, as shown in fig. 2, the video conference system includes a server layer, a user terminal layer, and a host layer, where the server layer includes a plurality of interactive servers and a streaming server, the user terminal layer includes a plurality of video terminals, the host layer is a video conference host, and each video terminal is connected to the video conference host through the interactive server and the streaming server. The video conference host can control the interactive server, the distribution server and the video terminal, and is generally arranged in schools or office places.
Specifically, the method comprises the following steps:
s1, after a grouping interaction instruction of the current video conference is obtained, the grouping interaction instruction is analyzed, and grouping interaction information of the current grouping is obtained, wherein the grouping interaction information comprises the number of video terminals participating in the current grouping interaction, the resolution ratio of the video conference, the frame rate and the network state of the video terminals.
And S2, calculating the packet interactive network requirement of the current packet according to the packet interactive information. The packet interactive network requirement is determined by the number of video terminals, video conference resolution and frame rate of current packet interactive participation, and is related to the number of video terminals, video terminal IP, video conference resolution, frame rate and network state of the video terminals. Specifically, the packet interactive network demand is calculated according to the number, resolution and frame rate of video terminals participating in packet interaction, and then the number of required streaming servers and interactive servers is calculated according to the bandwidths of the streaming servers and the interactive servers connected to the video terminals, so as to obtain the demand of the packet interactive network of the current packet. The requirements for different packets are different and need to be recalculated after each re-grouping.
And S3, constructing a service group of the current video conference according to the requirement of the packet interactive network, and providing services for the video terminal by the service group. The service group comprises a plurality of shunting servers and an interaction server.
Specifically, the step S3 includes the following steps:
step S31, acquiring the packet interactive network requirement, and judging whether a streaming server and an interactive server connected with the video terminal can meet the packet interactive network requirement or not; and when the requirements are met, the shunting server and the interactive server which are connected with the video terminal are directly combined into a service group of the current video conference, so that the service is provided for the video terminal. And when the streaming server and the interaction server cannot meet the packet interaction network requirement, executing step S32.
And step S32, acquiring the number of video terminals connected with all the current distribution servers and the interactive servers, selecting the distribution server and the interactive server with the least number of connected video terminals to construct a service group of the current video conference, and providing service for the video terminals.
And S4, when the preset conditions are met, automatically acquiring the packet interactive information of the current packet, calculating whether the service group can meet the packet interactive network requirements of the current packet, and dynamically adjusting the service group.
In principle, the switching of service groups is reduced as much as possible during the video conference, and the problem of pause or network delay is easy to occur during the switching process. Therefore, the service group is adjusted only when the preset condition is satisfied.
The preset condition comprises updating of the packet interaction information in the video conference or the fact that the packet interaction time reaches a preset period. In the video conference packet interaction process, a video conference host can automatically calculate whether a service group can meet the requirements of the current packet switching network within a certain period, and under the condition of meeting the requirements, the video conference host does not adjust the service group temporarily. And if not, re-executing step S32 to adjust the service group to meet the requirement of the video conference interaction grouping. Generally, the preset period is set to 10 minutes, so that abnormal conditions of the video conference caused by too high frequency and too low frequency due to too large calculation amount are avoided.
When the network video conference switches the speakers in the group in the grouping or switches the video conference host, a large amount of interactive protocols or network fluctuation can be generated, and the situation that the video conference is delayed and blocked even interrupted is easily generated. In this case, the de Zu Jiaohu information of the current packet needs to be obtained again, whether the service group can meet the packet interaction network requirement of the current packet is calculated, and the service group is dynamically adjusted.
The application provides a video conference packet interaction method, which comprises the steps of calculating the packet interaction network requirement of the current packet after acquiring the packet interaction instruction of the current video conference; and constructing a service group of the current video conference according to the requirements of the packet interactive network, providing services for the video terminal by the service group, providing a low-delay, high-quality and low-load video conference environment, ensuring the packet interactive stability of the video conference, and meeting the use requirements of users.
The present invention also provides a storage medium storing a computer program which, when executed by a processor, implements the steps of the aforementioned method for packet interaction for video conferencing.
The invention is operational with numerous general purpose or special purpose computing system environments or configurations. For example: personal computers, server computers, hand-held or portable devices, tablet-type devices, multiprocessor systems, microprocessor-based systems, set top boxes, programmable consumer electronics, network PCs, minicomputers, mainframe computers, distributed computing environments that include any of the above systems or devices, and the like.
