AI Technical Summary
Technical Problem
Existing technologies suffer from high latency issues in live video streaming, especially under the HTTP-FLV protocol, making it difficult to achieve low-latency live streaming without modifying the server.
Method used
By dynamically monitoring network jitter on the client side, adjusting the playback buffer of audio and video, calculating the jitter duration of audio and video using time windows, speeding up the processing of audio signals, and modifying the playback timestamp of video signals, low-latency live streaming can be achieved.
Benefits of technology
By minimizing changes to the HTTP-FLV distribution system, a low-latency live streaming experience was achieved, improving the smoothness of playback for users.

Abstract
本发明实施例提供了一种降低直播延时的方法及相关设备，可以最大限度的减小目前直播分发链路的改造，同时减低直播的延时。该方法包括：获取直播数据；对直播数据进行解析，以得到音频信息和视频信息；根据音频信息和视频信息分别计算目标时间窗口内的目标音频信号所对应的音频抖动时长以及目标时间窗口内的视频信号所对应的视频抖动时长；根据音频抖动时长以及视频抖动时长确定目标延时；根据目标延时以及当前缓存时长对目标音频信号进行调速处理；根据目标延时以及当前缓存时长修改目标视频信号的播放时间戳；将调速处理后的音频信号以及时间戳修改后的视频信号进行封装；基于封装后的音频信号和视频信号进行播放。
