伴随着流媒体技术的出现,Internet在视频和音频方面又具有新的活力。以往计算机网络由于视频、音频在传送过程中受到网络带宽方面的一些限制会出现流通不畅的现象。SMIL语言是一种在较高的语义层次上对多媒体对象进行组织和协调的文本格式,着重于媒体对象的同步和控制,而并不关心对象本身的内容,对多种同步方式的支持使其具有较大的灵活性。从功能的角度列举SMIL语言在多媒体课件点播中常见的应用,并就基于SMIL的网络流媒体课件方案构建模式及技术实现方法与流程进行探讨,以期对此类课件开发和传输能够提供一些启示。
With the advent of streaming technology, the Internet has renewed its vitality in video and audio. In the past, due to video and audio in the computer network during the transmission of the network bandwidth by some restrictions will appear the phenomenon of poor circulation. The SMIL language is a text format that organizes and coordinates multimedia objects at a relatively high level of semantic level. It focuses on the synchronization and control of media objects without concern for the content of the objects themselves. Support for multiple synchronization methods With greater flexibility. From the function point of view, the common applications of SMIL language in multimedia courseware on-demand are listed. And the construction mode and technical realization methods and process of network-based multimedia courseware based on SMIL are discussed in order to provide some inspiration for the development and transmission of such courseware.
