基于ADO的Web多媒体技术

A ADO-based Technique of Web Multimedia

Active X控件在 ASP中的内嵌及调用是 ASP的核心问题 ,而 ADO(Active X Data Objects)是Active X控件存储多类型、异构数据源并提供一致、高效数据接口的关键 ,ADO的灵活性和通用性使其在 Web多媒体技术应用中占有重要地位。针对 Web环境中图像、图形的数据库访问与管理 ,网络视频、音频文件的共享和访问 ,流媒体数据的回放控制等几个问题 ,结合 ADO技术的灵活性和独立于编程语言的特性 ,给出实用的解决方法 ,并提出数据优化的方法和性能分析。

It is the key problem to the ASP that Active Control is embedded and called in ASP, while ADO (Active Data Object) acts a key part in Active Control accessing multi type data and also gives a universal and highly efficient data interface. ADO has good flexibility and good compatibility. The main points focus on several problems, such as the access and the management of image file or graphic file in a Web Database circumstance, the share of video file and audio file in the net, the playback control of media streaming, etc. With the flexibility and the independence of language in ADO application, solutions are given and an optimized method and the performance are put forth.
