Design of Ship Audio Transmission System Based on Opus Algorithm
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.
