随着信息多样化的发展 ,信息的表现形式向组合化发展 ,而单一媒体不具备将信息的内容与其表现特征在时间与空间上同步统一的能力 ,为此多媒体和超媒体技术应运而生。MHEG标准定义了多媒体 /超媒体信息对象编码表示的最终形式 ,以及以该信息对象为单元在系统内部或系统间进行的交互 ,它在多媒体 /超媒体应用中 ,特别是交互式分布多媒体环境中将扮演非常重要的角色。文中介绍了多媒体和超媒体编码标准MHEG的发展历史、范围、特征及基本内容 ,解释了MHEG标准的基本思想 ,同时还对MHEG与MPEG、HTML等标准的区别与联系作了说明 ,分析了MHEG标准的应用现状和前景。
With the development of information diversification, the manifestation of information has developed into a combination. However, the single media does not have the ability to synchronize the content and performance characteristics of information synchronously in time and space. Therefore, multimedia and hypermedia technologies have emerged. The MHEG standard defines the final form of the multimedia / hypermedia information object coding representation and the interactions within or between systems based on this information object. It is used in multimedia / hypermedia applications, especially in interactively distributed multimedia environments Will play a very important role. This paper introduces the development history, scope, characteristics and basic content of MHEG coding standard of multimedia and hypermedia, explains the basic idea of MHEG standard, at the same time, it also explains the difference and connection between MHEG and MPEG, HTML and other standards, analyzes MHEG Standard application status and prospects.
