Apple, Ericsson and Sun Microsystems have joined forces to create a technology platform for delivering multimedia content, such as movie clips and news programmes, to wireless devices, the companies announced yesterday.

The companies plan to each focus on a certain area of the project, called the Ericsson Content Delivery Solution, with Apple using its QuickTime software for content creation and encoding, Ericsson focusing on wireless infrastructure, and Sun providing hardware and software for content delivery, the companies said.

"We would be the bridge between the content generated by Apple and the edge of the wireless infrastructure that Ericsson builds," said Videhi Mallela, a product marketing manager with Sun.

The three companies plan to offer the hardware and software package to mobile-phone network operators by the second half of this year, said Anette Jorgensen, a product marketing manager with Ericsson. The companies have not announced which network operators will use the equipment to offer services, she said.

The companies demonstrated the technology yesterday at the QuickTime Live! conference, said Brian Croll product marketing manager with Apple. The companies encoded an MPEG-4 video, streamed it through a Sun server and showed it on a television with a set-top box, a computer, and a wireless gadget from Ericsson. "This is create once, stream anywhere," Croll said.
