摘要:
To reduce communication time and charge and construct an information service system with higher user convenience, a server containing no map data transmits additional information to be presented on a map as data in specific format to navigation equipment or a PC each containing map data. The navigation equipment and the PC presents a map by adapting the data in specific format to the map data and then adding the information related to the data in specific format to the map.
摘要:
An audio apparatus (audio system) made up of the car-mounted audio apparatus 100 and portable audio apparatuses 200a and 200b transmits/receives contents data such as music via radio communication. As the communication system in this in-car radio communication, a short-distance data communication system is used, which allows respective apparatuses to recognize and authenticate with one another and perform data communication between those apparatuses.
