Japan-based mobile communications company NTT DoCoMo has chosen Apple's QuickTime 6 as its multi-media platform for all its future mobile phones.

Apple is paving the way for the move by introducing a version of QuickTime 6 that supports the 3rd Generation Partnership Project (3GPP) standard – a technology based on MPEG-4, which underpins Apple's QuickTime technology – later this year according to reports from Online Reporter.

MPEG-4 is an open-standard for encoding, decoding and transmitting digital video and audio to PCs, cell phones, set-top boxes and other wired and wireless Internet-connected devices.

NTT DoCoMo has 44 million subscribers in Japan, making it one of the world's largest cell phone service providers.

Last week DoCoMo announced the release of three mobile phones compatible with Apple's QuickTime 6.0 that allow users to view video clips.

The phones have camera lenses so users can record videos up to 15 seconds long and then email the video files to a PC or another mobile-phone user.

Apple is the first to support 3GPP, and DoCoMo will become the first service provider to implement it.

Brian Croll, Apple's senior director of Mac OS product marketing, said: "Apple has stood behind the MPEG-4 standard, and we're expanding out to a whole new platform, going from the PC to the phone system. This is exciting for us because the number of people using this standard is going to explode from people using this phone."
