摘要
在数字化语言实验系统中,由于采用了ATM技术,语音数据以"帧"且以固定速度传输,语音数据传输实时性好,无延时、无断裂,稳定性好,线路简单安全,同时视频点播通过特制的视频HUB,响应速度快、图像质量佳,保证了声像同步,避免了以太网中经常出现的视频点播的缓冲、停顿、马赛克及声像不同步等现象,且负载能力强,系统可靠,比单纯采用以太网络技术语言实验系统,语音、图象传输的质量更优,尤其是对今后ATM技术的发展能够桥接局域网和广域网世界,拓展了语言实验系统的使用.
In the digital language testing system, thanks to the ATM, voice data to "frame" and at a regular speed transmission, real - time voice data transfer, without delay, without breaking, stability, simple and safe, while line VOD through special video HUB, response speed, image quality, ensuring sound like synchronization, avoids Ethernet frequent buffering of VOD, pause, mosaic and sound like out - of - sync etc, and a load capacity of a strong, reliable, than just using a Ethernet network technology language experimental system, voice, image transmission quality better, as well as the future development of ATM technology is its ability to bridge local and wide area networks in the world, extending the use of language experimental system.
