Problems solved by technology

[0004] Most of the existing traditional LTE base stations do not optimize SIP signaling. In order to improve the user experience of Volte video in the poor air interface environment, it can only be realized by increasing the bandwidth supply. Moreover, the existing base stations do not have a dynamic adjustment strategy. SIP There is still a large gap in the signaling optimization inside the base station, and most of them are transparent transmission

Abstract

The invention provides a method and device for adjusting a video coding mode, a computer storage medium and equipment. The method includes the following steps: judging whether the air interface quality of a session terminal corresponding to the SIP signaling meets a preset coding mode adjustment condition; if the air interface quality of the session terminal meets the coding mode adjustment condition, judging whether the SIP signaling carries at least one coding mode description identification field, wherein the value set of each coding mode description identification field comprises a video coding mode description value corresponding to the coding mode that is currently supported by the session terminal; and if the SIP signaling carries at least one coding mode description identificationfield, setting a parameter value of the at least one coding mode description identification field as the video coding mode description value with the minimum bandwidth occupation in the correspondingvalue set. According to the scheme of the invention, the video coding mode of the current session is adjusted to the most bandwidth-saving coding mode that is currently supported according to the airinterface quality condition of the terminal, and the continuous video experience of users can be guaranteed.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, and in particular to a video encoding mode adjustment method, device, computer storage medium and equipment. Background technique [0002] In the field of wireless communication, the transmission of wireless links is often involved, and the quality of wireless transmission links is relatively unstable compared with wired transmission. In the process of poor and fluctuating air interface quality, traditional video coding cannot be dynamically adjusted. After the completion, there are problems of not being timely and not in place. Video customers tend to pay more attention to the fluency of calls. Compared with high-definition, freezing and low-definition, smooth, customers must prefer the latter. [0003] It can be seen that the existing video coding adjustment method has at least the following disadvantages: [0004] Most of the existing traditional LTE base stations do n...
