The TV device 5 has a general configuration for outputting a predetermined image or sound based on, for example, AV information output from the client terminal device 4, and detailed description thereof is omitted. It shall be.

Next, the pairing process will be described.
First, the IR blaster 32 of the server device 3 is attached to the IR blaster attachment portion 417 of the client terminal device 4. Specifically, the IR blaster 32 is attached to the client terminal device 4 such that the rectangular parallelepiped portion 210 of the IR blaster 32 is engaged with the engagement portion 71 of the IR blaster attachment portion 417.
As a result, the signal transmission unit 321 of the IR blaster 32 and the signal reception unit 411 of the client terminal device 4 are arranged to face each other (see FIG. 6).

Next, when the power of the server device 3 is turned on based on a predetermined operation of the power switch 314a of the operation unit 314 of the server device 3 by the user, the CPU 315a of the server device 3 is based on the execution of the pairing information transmission control program b1. Then, pairing information transmission processing for transmitting the pairing information stored in the ROM 315b from the signal transmission unit 321 of the IR blaster 32 is performed.

That is, it is not necessary to accurately grasp the position, orientation, and the like of the signal transmission unit 321 of the IR blaster 32 and the signal reception unit 411 of the client terminal device 3. In particular, the design is excellent in recent years, and the signal transmission unit 321 and the signal reception are excellent. Even if it is difficult to grasp the position and orientation of the part 411, the signal transmission part 321 and the signal reception part 411 of the IR blaster 32 are properly opposed by simply attaching the IR blaster 32 to the IR blaster attachment part 417. It will be possible to.
Further, in the client terminal device 4, the pairing process can be automatically performed based on the reception of the pairing information transmitted from the IR blaster 32.
Therefore, the pairing process can be easily performed.

The present invention is not limited to the above-described embodiment, and various improvements and design changes may be made without departing from the spirit of the present invention.
Hereinafter, modified examples of the client / server system will be described with reference to the drawings as appropriate.

<Modification 1>
In the client terminal device 104 constituting the client / server system according to the first modification, for example, an IR blaster mounting portion 417 is provided on the upper surface 401c of the terminal body 41 as shown in FIG. That is, in the first embodiment, the IR blaster mounting portion 417 is provided on the side surface portion 401a of the terminal body 41. However, the position of the IR blaster mounting portion 417 is not limited to this, and signal transmission of the IR blaster 32 is performed. Any position may be used as long as the unit 321 is disposed to face the signal receiving unit 411.

<Modification 2>
For example, as shown in FIGS. 9 and 10, the server device 203 configuring the client / server system according to the second modification includes an IR blaster 232 equipped with an attachment detection sensor 322 for detecting the attachment state with respect to the IR blaster attachment portion 417. The pairing information is transmitted from the signal transmission unit 321 based on the detection result by the attachment detection sensor 322.

That is, at a predetermined position of the mounting surface 713 continuous with the inner side surface portion 711 of the IR blaster mounting portion 417 of the client terminal device 204, for example, as shown in FIG. 11, a convex portion 713a protruding from the mounting surface 713 is provided. Is provided.
Further, for example, as shown in FIG. 10, the contact surface 211 of the IR blaster 232 is pressed by the convex portion 713 a of the mounting surface 713 based on the engagement of the rectangular parallelepiped portion 210 with the engaging portion 71. A contact-type attachment detection sensor 322 that detects attachment to the IR blaster attachment portion 417 is provided.
For example, when the attachment detection sensor 322 is pressed by the convex portion 713a, a predetermined detection signal is output to the server device 3 main body.
In the server device 3, based on the input of the detection signal, the CPU 315a transmits the pairing information from the signal transmission unit 321 based on the execution of the pairing information transmission control program b1. .

  Therefore, according to the client / server system of the second modification, the pairing process can be executed only by attaching the IR blaster 332 to the IR blaster attaching portion 417. As a result, it is not necessary to share the execution instruction of the pairing process with the predetermined operation of the power switch 314a as in the above embodiment, and an attractive client / server system with better operability can be provided.

<Modification 3>
The client / server system of Modification 3 can execute, for example, a process of canceling the pairing between the server device 303 and the client terminal device 304.

  For example, as shown in FIG. 13, the contact surface 211 of the IR blaster 332 is pressed by a predetermined convex portion 713 a formed on the mounting surface 713 based on the engagement of the rectangular parallelepiped portion 210 with the engaging portion 71. Thus, two contact-type attachment detection sensors 322A and 322B that detect attachment to the IR blaster attachment portion 417 are provided. That is, at a predetermined position of the mounting surface 713 of the IR blaster mounting portion 417, for example, as shown in FIG. 14, two convex portions 713a and 713a projecting from the mounting surface 713 are provided. Then, attachment detection sensors 322A and 322B are provided on the contact surface 211 of the IR blaster 332 so as to correspond to each of the convex portions 713a and have a spacing substantially equal to the spacing of the convex portions 713a.

The ROM 315b causes the CPU 315a to realize a function related to the pairing cancellation processing for transmitting the pairing cancellation information for canceling the pairing with the client terminal device 304 from the signal transmission unit 321 of the IR blaster 32 of the server device 303. The pairing release information transmission control program b2 is stored.
Here, the CPU 315a constitutes a pairing cancellation information transmission unit in cooperation with the signal transmission unit 321.

Further, the ROM 315b receives pairing information from the signal transmission unit 321 according to the number of the attachment detection sensors 322A and 322B that output the detection signal based on the input of the detection signals output from the attachment detection sensors 322A and 322B. A switching control program b3 for causing the CPU 315a to realize a function related to a transmission process switching control process for switching between a pairing information transmission process for transmitting a pairing cancellation information transmission process for transmitting pairing cancellation information is stored.
That is, the server device 303 differs in the number of attachment detection sensors 322A and 322B that output detection signals according to the attachment position of the IR blaster 32 with respect to the IR blaster attachment portion 417. For example, both of the two attachment detection sensors 322A and 322B When the IR blaster 332 is attached at the position where the detection signal is output (see FIG. 15A), the CPU 315a performs a process of switching to execute the pairing information transmission process based on the execution of the switching control program b3. Do. On the other hand, when the IR blaster 332 is attached at a position where either one of the two attachment detection sensors 322A and 322B (for example, the attachment detection sensor 322A) outputs a detection signal (see FIG. 15B), the CPU 315a switches between the two. Based on the execution of the control program b3, a process of switching to execute the pairing release information transmission process is performed.

  Therefore, according to the client / server system of the third modification, the pairing information transmission process and the pairing release information transmission process can be easily switched only by changing the mounting position of the IR blaster 332, so that the operability is further improved. It is possible to provide a good and attractive client / server system.

  Moreover, in the said modification 3, although LED which transmits pairing information and LED which transmits pairing cancellation | release information were shared as the signal transmission part 321 of IR blaster 332, it is restricted to this. For example, you may make it mount LED which transmits each information separately.
