2. The operation mode adjustment device according to claim 1 , wherein the detecting means is adapted to receive an ultrasonic signal or an electromagnetic radiation signal as an identification signal.

3. The operation mode adjustment device according to claim 2 , wherein the detecting means is adapted to receive a high-frequency signal or an infrared signal as an electromagnetic radiation signal.

4. The operation mode adjustment device according to claim 1 , wherein the adjusting means is adapted to adjust an operation mode based on a number of identification signals emitted per time unit by other operation mode adjustment devices and detected by the detecting means.

5. The operation mode adjustment device of claim 1 wherein the operation mode adjustment device is selected from one of a group consisting of a television, a monitor, a video recorder, a CD player, a DVD player, a projector, an audio player, a computer game device, a cellular phone, a box, and a hi-fi system.

6. The operation mode adjustment device of claim 1 wherein the operation mode adjustment device is a display device wherein the adjusting means is adapted to adjust an operation mode based on whether the detected environment is the shop environment or a home environment; and

the display device is operated with a better picture quality when the detected environment is the shop environment as compared to the case when the detected environment is the home environment.

7. The operation mode adjustment device of claim 1 wherein the operation mode adjustment device is a replay device having a reception unit for receiving a medium containing content to be replayed wherein the replay device is operated such that a medium received by the reception unit is prevented from being removed by a client when the detected environment is the shop environment.

8. An operation mode adjustment device for adjusting an operation mode of an electronic product connectable to the operation mode adjustment device, wherein the operation mode adjustment device comprises:

detecting means for automatically detecting whether an environment in which the electronic product connectable to the operation mode adjustment device is currently located is a shop environment;

adjusting means for automatically adjusting an operation mode of the electronic product based on whether the detected environment in which the electronic product connectable to the operation mode adjustment device is currently located is a shop environment; and,

wherein the detecting means is adapted to receive an identification signal emitted by the operation mode adjustment device and reflected by an environment in which an electronic product connectable to the operation mode adjustment device is currently located.

9. The operation mode adjustment device according to claim 8 , comprising an emitter unit adapted to emit the identification signal.

10. The operation mode adjustment device according to claim 9 , wherein the emitter unit is adapted to periodically emit the identification signal.

11. The operation mode adjustment device according to claim 9 , wherein the emitter unit is adapted to emit the identification signal including information that the electronic product is related to a particular company.

12. The operation mode adjustment device according to claim 9 , wherein the emitter unit is adapted to emit an ultrasonic signal or an electromagnetic radiation signal as the identification signal.

13. The operation mode adjustment device according to claim 12 , wherein the emitter unit is adapted to emit a high-frequency signal or an infrared signal as an electromagnetic radiation signal.

14. The operation mode adjustment device according to claim 8 , wherein the adjusting means is adapted to adjust an operation mode based on reflection characteristics of the identification signal detected by the detecting means and reflected by an environment in which an electronic product connectable to the operation mode adjustment device is currently located.

15. The operation mode adjustment device according to claim 14 , comprising a reflection profile storage means adapted to store a plurality of reflection profiles each being characteristic of a particular environment, wherein the detection means is adapted to compare reflection characteristics of the identification signal detected by the detecting means with any one of the plurality of reflection profiles.

16. A method of adjusting an operation mode of a first electronic product, the method comprising the steps of:

receiving, by the first electronic product, an identification signal emitted by an operation mode adjustment device that adjusts an operation mode of a second electronic product;

automatically detecting whether an environment in which the first electronic product is currently located is a shop environment by analyzing a frequency of occurrence of the received identification signal; and

automatically adjusting an operation mode of the first electronic product based on whether the detected environment in which the first electronic product is currently located is a shop environment.

17. A non-transitory computer-readable medium, in which a computer program is stored which, when being executed by a processor, is adapted to carry out a method of adjusting an operation mode of a first electronic product, the method comprising the steps of:

receiving, by the first electronic product, an identification signal emitted by an operation mode adjustment device that adjusts an operation mode of a second electronic product;

automatically detecting whether an environment in which the first electronic product is currently located is a shop environment by analyzing a frequency of occurrence of the received identification signal; and

automatically adjusting the operation mode of the first electronic product based on whether the detected environment in which the first electronic product is currently located is a shop environment.
