浪涌式的信息化建设,促进了宽带应用的迅速普及,而2003年发生的“非典”更是引爆了人们对更高层次互动式沟通方式的需求,这一切都为视频业务新的发展提供了契机,驱使视频业务迈出“黄金屋”,走向大众,让视频通信运营者摆脱先前“独上高楼望尽天涯路”的感觉。目前,中国的视频通信市场处于群雄争霸的时期,众多厂商纷纷挤入这个新兴的领域,产品种类琳琅满目且遵循的标准繁杂。由于人们对可视通信的具体实现还没有统一的认识,一些用户尤其是专网用户,对标准接触很少,因此在选择视频产品时比较盲目,不知道如何判断。为此,本期专题从标准化的角度出发,组织了一批视频方面的文章,主要包括视频网络的组织、视频应用的实现、视频设备的构成如何适应新型的网络、基于不同体系结构的视频网络如何实现互通,并对目前市场上的视频终端产品进行了深入分析,希望对大家能有所裨益。
The surge of informatization has promoted the rapid popularization of broadband applications. However, the SARS that took place in 2003 detonated the demand for higher-level interactive communication, all of which provided new development for video services The opportunity to drive the video business took the “Golden House”, to the general public, so that video communications operators to get rid of the previous “alone on the road to the horizon,” the feeling. At present, China’s video communications market is in a heyday period, many manufacturers have squeezed into this emerging field, an assortment of products and follow the standard complex. As people do not have a unified understanding of the concrete realization of visual communication, some users, especially private network users, have little contact with the standard, so they are blind when choosing video products and do not know how to judge. To this end, this issue from the standardization point of view, organized a number of video articles, including video network organization, the realization of video applications, the composition of video equipment how to adapt to the new network, based on different architectures of the video network How to achieve interoperability, and on the market in the video terminal products conducted in-depth analysis, I hope everyone can benefit.
