Abstract: We have developed the world|s first live video distribution platform capable of simultaneously delivering live video to multiple mobile phones, e.g. mobile videophone terminals and PDAs (Personal Digital Assistants), as a 3rd-generation (3G) mobile communications service. Although we are already providing a one-to-one moving picture delivery (videophone) service as a 3G mobile phone service, we did not yet have a one-to-many system of delivering live video to multiple terminals. The new platform delivers video to terminals using the bearer of a 3G-324M line provided with 3G mobile communications servics. The same content can be delivered simultaneously in a maximum of 500 streams to mobile phones with a video delay of approximately 7 seconds, a picture size of 176 x 144 pixels, and a frame rate of 10 fps. This paper also summarises the possibilities of using this platform to create business models that use a mobile videophone to provide a child care centre monitoring system, a home remote monitoring system, or other systems that were not possible with existing mobile phones.

Keywords: 3G-cellular phone; TV phone; MPEG4; video streaming; live contents.
