In general we may think that in order want iTunes to handle different media file, just as it adds more encoder on it. In fact, it is not really doing it so simple. .iTunes now supports Apple Lossless format, AAC, AIFF, and MP3 audio , and you need to cost no DRM WMA files format and WAV format. Video support is limited support for H.264 and MPEG-4 video files. However, it does not support such as Ogg Vobis, WMA and real WMV, DivX, MKV , FLV, etc.. .We suspect Herve Leger that Apple will not go to support these formats, and probably never will, because it did not want to come support them.For example, if Apple supports protected WMA files, which not only only have to pay royalties to Microsoft, this can put iTunes store customers to switch to rival camp. .8, complete multi-room support .when Apple introduced it in 2004 when the AirPort Express, it's selling point of the One is that, through iTunes, AirTunes, you can high-quality sound system to play music. .disadvantage is that Apple can not let you sit in front of the computer can be done without all the control. It has been over the past few years , we still need third-party solution to achieve this operation.
