摘要
针对传统航行数据记录仪音频数据采用本地存储,在发生重大水上事故时,存储介质寻找过程漫长且内部的音频数据回放困难等问题,设计音频系统中的Opus自适应编解码算法和网页实时通讯传输方案,实现音频数据的无线传输和岸基管理平台回放.经验证,设计的编解码算法与网络传输系统性能满足检验指南音频质量STI≥0.6 的要求.
Abstract
In view of the traditional navigation data recorder audio data is stored locally.In the event of a major maritime ac-cident,the process of searching storage media is long and the internal audio data playback is difficult.The Opus adaptive enco-ding and decoding algorithm in the audio system and the real-time communication transmission scheme of web page were designed to realize the wireless transmission of audio data and the playback of shore-based management platform.It had been verified that the designed codec algorithm and the performance of the network transmission system meet the requirements of audio quality STI≥0.6 in the inspection guide.
