Abstract

This paper presents a contents delivering system for mobiles with Infrared devices that support IrOBEX. To realize digital contents broadcasting service by infrared communication, we developed a new Inrared data delivering protocol IrFAST and implemented the protocol in a Palm PAD platform already. It is not easy to implement the protocol IrFAST in most of mobile, because the mobile makers do not open the platform sources in their mobile products and also most mobiles do not support lower layer development. But recently more and more mobiles such as FOMA by NTT Dodomo have IrOBEX on board and also allow users to access IrOBEX in Java application. Therefore, we developed a portable infrared receiver, which support both IrFAST and IrOBEX. With our infrared receiver, we can get and save the broadcasting data with IrFAST protocol, then transfer the received data to a mobile with IrOBEX. The mobile users can browser the data transferred from the infrared receiver, and even access the URLs Those are included in the data. Here, we will introduce the system and devices, and give an outline about the every parts in the system. In order to confirm the performance of the infrared digital contents delivering system and its devices, we have been carrying out an experiment with more than 100 monitors in a university campus. This experimental broadcasting system provides teaching and living information and other commercial information. We hope that we not only confirm the performance of the infrared protocol and system, but also find some new application model for the new infrared broadcasting service.
