Data transmitting and receiving system, data receiving apparatus, and data transmitting apparatus

摘要

A video game apparatus (1) has a package medium demodulator (6) for a package medium (100) having an ID such as a disk number and a CPU (5). The CPU (5) reads a certain program and/or data from the package medium (100) via the package medium demodulator (6) and executes the program and/or processes the data if a disk number designated by data received via an antenna (2) and a communication data demodulator (3) agrees with the disk number of the package medium (100) which is read by the package medium demodulator (6).
