Abstract

According to one embodiment, a first interface unit executes a process of transmitting a remote-control code belonging to a first remote-control code set which is supported by a first operating system (OS#1) to an operating system which is currently executed. A second interface unit executes a process of transmitting a remote-control code belonging to a second remote-control code set which is supported by a second operating system (OS#2) to the currently executed operating system. If the currently executed operating system is OS#1, a control unit prohibits transmission of the remote-control code from a receiving unit to the second interface unit, and permits the first interface unit to execute the process. If the currently executed operating system is OS#2, the control unit permits transmission of the remote-control code from the receiving unit to the second interface unit, and prohibits execution of the process by the first interface unit.

Claims

1. An information processing apparatus comprising:

a receiving unit configured to receive a remote-control code corresponding to at least one of a first remote-control code set and a second remote-control code set, the first code set supported by a first operating system and the second code set supported by a second operating system;

a first interface unit connected to the receiving unit and configured to induce the execution of the remote-control code by an operating system that is currently executed by the information processing apparatus when the remote-control code corresponds to the first code set;

a second interface unit connected to the receiving unit and configured to induce the execution of the remote-control code by the operating system that is currently executed by the information processing apparatus when the remote-control code corresponds to the second code set;

a determination unit configured to determine whether the operating system that is currently executed by the information processing apparatus corresponds to either the first operating system or the second operating system; and

a control unit configured to prohibit transmission of the remote-control code from the receiving unit to the second interface unit and to permit processing of the remote-control code by the first interface unit when it is determined that the operating system that is currently executed by the information processing apparatus is the first operating system, the control unit further configured to permit transmission of the remote-control code from the receiving unit to the second interface unit and to prohibit processing of the remote-control code by the first interface unit when it is determined that the operating system that is currently executed by the information processing apparatus is the second operating system.

2. The information processing apparatus according to claim 1, wherein each of the first code set and the second code set comprise at least one common code that can be executed by either the first operating system or the second operating system.

3. The information processing apparatus according to claim 1, wherein each of the first code set and the second code set comprise a power-on code, and wherein the first interface unit is configured to power-on the information processing apparatus when the first interface unit receives the power-on code corresponding to either the first code set or the second code set.

4. The information processing apparatus according to claim 1, wherein the receiving unit comprises:

a light-receiving unit configured to receive an infrared signal corresponding to at least one of a first received remote-control code belonging to the first code set and a second received remote-control code belonging to the second code set; and

a remote-control receiver configured to extract the first received code from the infrared signal and to transmit the first received code to the first interface unit, the remote-control receiver further configured to extract the second received code from the infrared signal and to transmit the second received code to the second interface unit, wherein the remote-control receiver is connected to the second interface unit via a switch circuit; and

wherein the control unit is configured to prohibit transmission of the second received code to the second interface unit by turning off the switch circuit when the operating system that is currently executed by the information processing apparatus corresponds to the first operating system, and wherein the control unit is configured to permit transmission of the second received code to the second interface unit by turning on the switch circuit when the operating system that is currently executed by the information processing apparatus corresponds to the second operating system.

5. The information processing apparatus according to claim 1, wherein the receiving unit comprises:

a light-receiving unit configured to receive an infrared signal corresponding to at least one of a first received remote-control code belonging to the first code set and a second received remote-control code belonging to the second code set;

a first remote-control receiver configured to extract the first received code from the infrared signal and to transmit the extracted first code to the first interface unit; and

a second remote-control receiver configured to extract the second received code from the infrared signal and to transmit the extracted second code to the second interface unit, and

wherein the control unit is configured to prohibit the second remote-control receiver from transmitting the extracted second code to the second interface unit when the operating system that is currently executed by the information processing apparatus corresponds to the first operating system, and wherein the control unit is configured to permit the second remote-control receiver to transmit the extracted second code to the second interface unit when the operating system that is currently executed by the information processing apparatus corresponds to the second operating system.

6. A remote-control code transmission control method for controlling transmission of a remote-control code to a processor currently executing an operating system in an information processing apparatus having a receiving unit configured to receive remote-control codes each corresponding to at least one of a first remote-control code set supported by a first operating system and a second remote-control code set supported by a second operating system, a first interface unit for processing the first code set, and a second interface unit for processing the second code set, the method comprising:

determining whether the currently executing operating system comprises the first operating system or the second operating system;

prohibiting transmission of remote-control codes from a receiving unit to the second interface unit and permitting the first interface unit to process the remote control code when the operating system that is currently executed by the information processing apparatus is determined to be the first operating system; and

permitting transmission of remote-control codes from the receiving unit to the second interface unit and prohibiting processing of remote-control codes by the first interface unit when the operating system that is currently executed by the information processing apparatus is determined to be the second operating system.

7. The remote-control code transmission control method according to claim 6, wherein each of the first remote-control code set and the second remote-control code set comprise at least one common code that can be executed by either the first operating system or the second operating system.

8. The remote-control code transmission control method according to claim 6, further comprising powering-on the information processing apparatus when the first interface unit receives via the receiving unit a power-on code corresponding to either the first code set or the second code set.

9. The remote-control code transmission control method according to claim 6, wherein the receiving unit comprises a light-receiving unit configured to receive an infrared signal corresponding to at least one of a first received remote-control code belonging to the first code set and a second received remote-control code belonging to the second code set, and a remote-control receiver configured to extract the first received code from the infrared signal and transmit the extracted first code to the first interface unit, and the remote control receiver configured to extract the second received code from the infrared signal and transmit the extracted second code to the second interface unit, wherein the remote-control receiver is connected to the second interface unit via a switch circuit;
