摘　　要：分析了当前形势下船舶交通管理系统(VTS)数据记录重放的重要性和需求,针对其中高效存储、同步回放和话音连贯3个难点问题,提出了从记录存储、播前下载到同步回放全流程设计的综合解决方案,并重点分析了录屏方式、景象数据压缩、基于虚拟时钟的加速重放以及双线程和双缓冲机制等关键技术。鉴于该方案存在不足,提出了利用集成专用硬件设备提高景象数据录取和存储效率的设计思路。The importance and demands of the recording and replay of data in the modern vessel traffic service （VTS） are analyzed. Aimed at three problems of efficient storage, synchronous re- play and voice continuous playback, the integrated process of recording, the pre-download and synchronous replay is proposed. Some key problems and techniques are analyzed, such as record- ing method, vision data compressing, and accelerated playback based on the virtual clock and the mechanism of double-threads and double buffering. The idea for improving the efficiency of data recording and storing by using dedicated device is given.
