Embodiment Construction

[0035] Hereinafter, exemplary embodiments according to the present application will be described in detail with reference to the accompanying drawings. Apparently, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments of the present application. It should be understood that the present application is not limited by the exemplary embodiments described here.

[0036] Application overview

[0037] At present, when live broadcasting, two playback modes, constant bit rate (CBR) and variable bit rate (VBR), are mainly used.

[0038] Figure 1A A graph illustrating bitrate and image quality when playing at a constant bitrate. Such as Figure 1A As shown, the solid line in the figure represents the instantaneous code rate, and it can be seen that the instantaneous code rate basically remains unchanged. However, in this case, the image quality (such as Figure 1A (shown by the dotted line) changes greatly. Moreover, wh...

Abstract

The invention relates to an access control method and a device for large-scale live broadcast, and electronic equipment. The method comprises the steps of acquiring the screen resolution of each user;calculating the average occupied bandwidth of each user according to the screen resolution of each user and the peak code rate of the variable code rate; calculating an increasable user number according to the average occupied bandwidth of each user, the current total user number and the current total bandwidth; and executing an access control operation based on the increasable user number. In this way, proper access control can be performed, thereby giving consideration to both cost and user experience.

Description

technical field [0001] The present application generally relates to the technical field of access control, and more specifically, relates to an access control method, device and electronic equipment for large-scale live broadcasting. Background technique [0002] With the rapid development of Internet technology, online video live broadcast is becoming more and more popular. All kinds of activities can be presented to users through live broadcast, such as press conferences, sports competitions, trade exhibitions, teleconferences, etc. [0003] Due to its interactivity and real-time characteristics, online video live broadcasting has been welcomed by more and more users. Therefore, the number of users participating in online video live broadcasting has also gradually increased. [0004] Correspondingly, for the continuously increasing number of users, it often occurs that the available network bandwidth cannot meet the needs of the users. However, if the service provider si...
