Abstract
The present invention provides a digital data transmitting/receiving method, a base station unit, and a mobile object terminal unit, which enable collection of information desired by the mobile object terminal among service information distributed by the base station by using a broadcasting channel. The base station transmits data after identification information is added in the header information of the service information provided to the mobile object terminal, and the mobile object terminal has an address showing the identification information. The mobile object terminal analyzes the identification information by indicating the address to identify whether the service information is provided to the terminal.
