方法/步骤:
一、itunes是什么意思
iTunes是Mac和PC使用的免费数字媒体播放应用程序,可以管理和播放数字音乐和视频。 苹果电脑于2001年1月10日在旧金山的Macworld Expo上发售。iTunes程序管理苹果电脑iPod数字媒体播放器上的内容。 iTunes还可以连接到iTunes Store (如果有网络连接),下载购买的数字音乐、音乐视频、电视节目、iPod游戏、各种Podcast和标准长片。
iTunes可以从苹果电脑的网站免费下载获得。 此外,还附带所有Macintosh计算机和一些iPod,提供给Macintosh。 它也是苹果电脑iLife多媒体应用工具包的一部分。
二、iTunes功能
1 .媒体管理
iTunes将有关音频文件的元数据存储在两个文件中。 第一个是名为iTunes Library的二进制文件(在以前的版本中称为iTunes x Music Library ),使用自己的歌曲库格式。 不仅缓冲艺术家和流派等音频文件的标签空间(ID3标签等)中保存的信息,还缓冲“播放计数”和“采样率”等iTunes特殊信息。 第二个文件名是iTunes Music Library.xml,在iTunes信息更改时更新。
2 .数据库视图
iTunes用户可以用多种方法阅览iTunes视频数据库,包括目录、目录附带适当的封面图像、网格阅览模式或Coverflow。
3 .数据库共享
iTunes音乐数据库中的歌曲可以使用Bonjour (以前称为Rendezvous )在局域网上共享。 这是苹果的Zeroconf (无需设定,Zero Configuration Required )开放网络标准。 通过该技术,可以自动共享和检测同一子网段内的歌曲。 如果一首歌被共享,iTunes会将这首歌播放到另一台计算机上,但不能保存它以免被复制。 也可以访问使用版权保护AAC的歌曲,但需要iTunes Music Store获得许可。 每24小时最多允许5个用户连接。
4 .文件格式支持
iTunes 9现在可以在MP3、AIFF、WAV、MPEG-4、AAC和苹果lossless之间读取、写入和转换。
iTunes可以播放任何QuickTime (也是某些视频格式),包括受iTunes Store和Audible.com有声文件保护的AAC文件。 要播放其他格式(如Vorbis和Speex代码,包括Ogg ),iTunes必须安装Xiph QuickTime组件。
总结:以上就是itunes是什么意思的介绍,希望对大家有所帮助。
