Portable electronic device, entertainment system and method of operating the same

An entertainment system comprising a host machine having a program-execution function and subordinate machine having an interface for connecting to said host machine, said host machine transferring a program-execution information to said subordinate machine, said subordinate machine comprising:

• an identification-number holding means for holding a proper identification number;
• an input-operation means for executing an input operation;
• an operation-information generation means for generating operation information in response to the input operation from said input-operation means;
• an operation-information storage means to storing operation information from said operation-information generation means;
• a character-information generation means for generating proper character information in accordance with said operation information and gene information, upon receiving via said host machine said gene information which determines a character-transmission factor corresponding to said proper identification number.

A method for operating an entertainment system comprised of a host machine having a program-execution function and subordinate machines made of portable electronic devices having an interface for connecting to said host machine, the method for operating an entertainment system comprising the steps of:

• (a) providing said subordinate machines with proper identification numbers, and providing said host machine with gene information that corresponds to said identification numbers;
• (b) connecting said subordinate machines to said host machine, and sending said proper identification numbers from said subordinate machines to said host machine;
• (c) loading the subordinate machines with gene information by said host machine, on confirming the identification numbers sent from said subordinate machines;
• (d) generating by said subordinate machines character information based on said gene information and displaying proper characters in their display means.
