Abstract

The present invention relates to an information processing terminal that makes it possible to readily upgrade software of information processing terminals connected by a network. When a control program stored in a display apparatus 5B is upgraded by a control program stored on a memory card 10, an upgrade program for a base station 1 and the control program for display apparatus 5A and 5B read by the display apparatus 5B are transmitted to the base station 1. The base station 1 upgrades a control program stored therein by the upgrade program received by the base station 1, and also transmits the control program for the display apparatus 5A and 5C to the display apparatus 5A and 5C. The display apparatus 5A and 5C each upgrade a control program stored therein by the upgrade program received by the display apparatus 5A and 5C, respectively.

Claims

said communicating means transmits a second control program stored on said recording medium to said information processing apparatus to upgrade an old said second control program.

2. An information processing terminal as set forth in claim 1, characterized in that:

said communicating means transmits to said information processing apparatus said second control program for said information processing apparatus corresponding to said first control program obtained by the rewriting of said control program rewriting means.

3. An information processing terminal as set forth in claim 1, characterized in that:

said storing means can store a plurality of said first control programs; and

said control program rewriting means rewrites only one of the plurality of said first control programs.

4. An information processing method characterized by comprising:

a communicating step for communicating with an information processing apparatus by radio;

a storing step for storing a first control program; and

a control program rewriting step for rewriting said first control program stored by processing of said storing step;

wherein processing of said control program rewriting step rewrites the old said first control program stored by the processing of said storing step on the basis of a new said first control program stored on a removable recording medium; and

processing of said communicating step transmits a second control program stored on said recording medium to said information processing apparatus to upgrade an old said second control program.

5. A recording medium having a computer readable program recorded thereon, said program characterized by comprising:

a communicating step for communicating with an information processing apparatus by radio;

a storing step for storing a first control program; and

a control program rewriting step for rewriting said first control program stored by processing of said storing step;

wherein processing of said control program rewriting step rewrites the old said first control program stored by the processing of said storing step on the basis of a new said first control program stored on a removable recording medium; and

processing of said communicating step transmits a second control program stored on said recording medium to said information processing apparatus to upgrade an old said second control program.

6. An information processing terminal characterized by comprising:

communicating means for communicating with an information processing apparatus by radio;

storing means for storing a control program; and

control program rewriting means for rewriting said control program stored by said storing means;

wherein said control program rewriting means rewrites the old said control program stored by said storing means on the basis of a new said control program obtained by said communicating means from said information processing apparatus.

7. An information processing terminal as set forth in claim 6, characterized in that:

said storing means can store a plurality of said control programs; and

said control program rewriting means rewrites only one of the plurality of said control programs.

8. An information processing terminal as set forth in claim 6, characterized in that:

said communicating means obtains a new said control program transmitted from another information processing terminal to said information processing apparatus.

9. An information processing terminal as set forth in claim 6, characterized by further comprising rewriting prohibiting means for prohibiting the rewriting of said control program by said control program rewriting means.

10. An information processing method characterized by comprising:

a communicating step for communicating with an information processing apparatus by radio;

a storing step for storing a control program; and

a control program rewriting step for rewriting said control program stored by processing of said storing step;

wherein processing of said control program rewriting step rewrites the old said control program stored by the processing of said storing step on the basis of a new said control program obtained by processing of said communicating step from said information processing apparatus.

11. A recording medium having a computer readable program recorded thereon, said program characterized by comprising:

a communicating step for communicating with an information processing apparatus by radio;

a storing step for storing a control program; and

a control program rewriting step for rewriting said control program stored by processing of said storing step;

wherein processing of said control program rewriting step rewrites the old said control program stored by the processing of said storing step on the basis of a new said control program obtained by processing of said communicating step from said information processing apparatus.

13. An information processing apparatus as set forth in claim 12, characterized in that:

when a plurality of said information processing terminals are provided, said communicating means transmits a said control program obtained from a first said information processing terminal to a second said information processing terminal to upgrade a said control program of the second said information processing terminal.

12. An information processing apparatus characterized by comprising:

communicating means for communicating with an information processing terminal by radio;
