摘要

我们实现了一种基于高阶双声(HOA)的高清3D视听再现系统，使用环绕157扬声器阵列结合3D投影显示器来再现具有高临场感的信息。在本报告中，我们介绍了系统的概况，并对如何实现良好的系统同步进行了研究，这是我们一直致力于的。调查结果表明，所有157个扬声器声道在单采样电平(48 kHz)内完全同步，使用单个PC机与三个多声道音频数字接口(MADI)系统控制。157个音频信号和视频信号的延时仅为1.1 ms左右。

Implementation of a high-definition 3D audio-visual display based on higher-order ambisonics using a 157-loudspeaker array combined with a 3D projection display

We have implemented a high-definition 3D audiovisual reproduction system based on higher-order ambisonics (HOA) using a surrounding-157-loudspeaker array combined with a 3D projection display to reproduce information with high sense-of-presence. In this report, we introduce the system overview as well as an investigation to realize good system synchronization, which we are keenly devoted to. Results of the investigation show that all 157 channels of loudspeakers were completely synchronized within the one-sample level (48 kHz) controlled using a single PC with three Multichannel Audio Digital Interface (MADI) systems. Moreover, the latency among 157 audio signals and the video signal was only about 1.1 ms.
