Information processing system connected by radio communication
First Claim
1. A data processing apparatus comprising:
- receiving means for receiving a carrier wave which is modulated by data;
identifying means for identifying a frequency of the received carrier wave;
extracting means for extracting the data by demodulating the received carrier wave;
a plurality of data interpreting means; and
table means for storing a correspondence of each data interpreting means to a frequency of the carrier wave,wherein said apparatus selects one of said plurality of data interpreting means in accordance with the frequency of the received carrier wave identified by said identifying means and a content of said table means, and causing the selected one of said plurality of data interpreting means to interpret the extracted data.

Abstract
To control an information processing system in which a host unit is connected by radio communication to a slave unit, the host unit transmits data and carrier waves both containing ID information selecting a specific information process, and the slave unit recognizes the ID information, thus performing its operation accordingly. A difference in frequencies of the carrier waves is regarded as a type of ID information. The slave unit identifies a frequency, receives data corresponding to the frequency, and performs the specific information process on the basis of the data received at this frequency. The information processing system, especially that composed of a slave unit and host units, thus constructed and controlled is capable of operating efficiently, without wasting electricity.

9. A data processing method comprising the steps of:
-
identifying a frequency of a carrier wave upon receipt of the carrier wave modulated by data; selecting one of a plurality of data interpreting means in accordance with the frequency of the received carrier wave identified in said identifying step, a selection being made by using a table which previously stored a correspondence of each data interpreting means to a frequency of a carrier wave; and interpreting data obtained by demodulating the received carrier wave utilizing a selected data interpreting means. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17)
