摘要
针对远程支援对装备保障现场音视频数据的实际需求,基于LabWindows/CVI软件开发平台,设计并实现了一种音视频采集与压缩系统。该系统运用虚拟仪器多线程技术有效保证了音视频数据采集的实时性,并采用MPEG-4标准进行音视频数据的压缩,有效提高了数据共享的效率。测试结果表明,使用本系统方案有效减小了音视频数据延迟,提高编码器压缩效率和系统的稳定性,可直接应用于远程支援系统。
The remote supporting system has high requirements for audio and video data of the equipment support scene. A real-time audio and video data acquisition and compression system is designed and realized under the LabWindows/CVI software development platform. With the multi-thread tech- nology of virtual instrument, this system can acquire data in real time. The remote sides can share data effectively with the application of MPEG -4 com-pression algorithm. Test results show that the delay in data acquisition is very low, the data compression efficiency is high, and this system works relia- bly. This system can be used directly in remote supporting system.
