Abstract

The invention applies to the technical field of communication and provides a correction method and device for a frame loss rate and a terminal. Through utilization of the correction device for the frame loss rate, after a computing mode of the frame loss rate is determined according to an acceleration mode variable, when it is determined that a current congestion code frame is not a frame I or a first frame P following the frame I, the frame loss rate is computed according to the determined computing mode. A current congestion code is coded according to the frame loss rates obtained through computing based on different computing modes, so the coding efficiency is improved, moreover, the fluency degree of a video is ensured, the playing quality of the video is ensured, the balance between the fluency degree and the playing quality is balanced, and the user experience is relatively good.

Description

technical field [0001] The invention belongs to the technical field of communications, and in particular relates to a frame loss rate correction method, device and terminal. Background technique [0002] In the case of concentrated concurrent users and unstable mobile channels, there will be problems such as network congestion, video freezing, and frequent buffering. At this time, user experience will drop sharply. In order to improve the user experience, the commonly used solutions are to drop frames and distribute low-bit-rate video streams. Because the sensitivity of the human eye to the frame rate is much lower than the playback quality of the video image, the method of dropping frames has a good advantage in the case of occasional network congestion. [0003] However, in the above two solutions, the diversity of video sources is ignored, and a unified frame loss strategy is adopted, which makes the smoothness of the video and the playback quality of the video unbalance...
