1、 I 基于 AS3.0 的音乐点播系统的设计与实现 摘 要 在多媒体技术高速发展的今天，多媒体播放器出现了多种缺点和毛 病，主要表现在内存大量占用和操作复杂繁琐方面。本文针对当今流行 音乐播放器的优缺点进行了研究，然后在此基础上进行综合和总结，开 发出了一个功能丰富和操作简易的音乐点播系统，该播放器具有低内存 占用和绿色无广告的特点，因此具有广阔的市场前景。本音乐点播系统 是基于脚本语言 ActionScript3.0，利用 FlashBuilder4.6 设计开发的 AIR 应用程序。主要利用 Actionscript3.0 作为后台逻辑处理和功能实现，文 中对音乐播放器做了详细的需求分析，
2、并详细介绍了音乐播放器的总体 设计，包括音乐播放器的架构设计、功能模块的划分、音乐播放列表文 件的设计、常用工具的设计、本地数据存储设计等，然后具体介绍了以 上各个部分和功能的具体实现原理和过程，最后再对该音乐点播系统进 行了黑盒测试和白盒测试，没有重大的异常和错误，证明其设计方案的 可行性和正确性。 关键词：多媒体；播放器；人性化 II Design and Implementation of Music-on-demand System Based on AS3.0 Abstract With the rapid improving of the times and the rapid d
