The new version of QuickTime software can be used to develop, create, deliver high quality video or audio information on IP wireless networks and broadband networks. Excellent MPEG-4 video codecs and a proven H.263 video codec can provide a high quality image with a lower data rate. The new AAC audio codec can provide high quality music in multiple data rates, while AMR provides voice-specific narrowband video encoding. The 3G text supported by QuickTime 6.3 is based on time, so that the subtitles and sounds reach precise synchronization.
According to Apple QuickTime Product Marketing Supervisor Frank Introduction: QuickTime 6 Series since the release of 1,75 million users have been downloaded in just 18 months, in addition to this, it has also obtained many mobile operators And the favor of mobile phone manufacturers.

The 3G service allows users to enjoy the 'I-Motion' video clip allocation and 'i-motion mail' video editing email," NTT Docomo I-MODE Planning Takeshi Natsuno, General Manager, said, "It's exciting, QuickTime 6.3 helps NTT DoCoMo users achieve standard content creation and desktop play, so they can share mobile phones with friends and family on the MAC or PC. "
Janne Juhola, senior technical manager, Nokia Multimedia, said, "Nokia is very welcome to support 3GPP format and codec's QuickTime 6.3, we have always been committed to establishing a public standard to make large numbers, networks, services and applications. Synergistic ecosystem. Nokia believes QuickTime 6.3 support for 3GPP will bring a series of new attractive opportunities for desktop computers and mobile phone users. "
