Description

  The present invention relates to a system capable of remote control by sending a remote control code to a desired electronic device via a network between devices connected to the network, for example, and the remote control code is directly input to the desired electronic device. Also relates to a network system that does not impair the usability of electronic equipment used as a monitor during remote operation.

  Conventionally, a remote control is provided for each device to be controlled. For example, a television receiver (hereinafter abbreviated as TV) controls channel, volume, power ON / OFF, etc. with a TV remote control. Video tape recorders (hereinafter referred to as VTRs) used the VTR remote control for recording / playback, fast forward / rewind control, and so on. Therefore, if there were many controlled devices, there were as many remote controls as there were.

  In order to improve this, proposals have been made to control multiple controlled devices with a single remote control.

  For example, in Patent Document 1, information for controlling each home appliance connected to the network is registered in the supervisor unit of the central management device, and the remote controller communicates with the supervisor unit to obtain control information of a desired home appliance. The menu is displayed on the remote controller, and a desired operation instruction is sent to the supervisor. The supervisor receives the instruction and controls the operation of each home appliance via the network.

  Similarly, in Patent Document 2, when a controlled device is connected to a network, the control device registers information for controlling the controlled device in the control device, and the remote control specifies the device to be controlled displayed on the controlled device. Select and display what instruction key is assigned to the controlled device selected by each key switch of the remote controller, and perform a desired remote controller operation. Alternatively, communication is performed to obtain control information of a desired controlled device, key information corresponding to a display provided in the remote control is displayed, a desired operation instruction is sent to the control device, and the controlled device is received via the network. The operation is controlled.

  However, in the conventional example (Patent Document 1), an instruction is given to the supervisor. Therefore, in order to control each desired device without changing the place of remote control operation, it is necessary to change to a remote controller dedicated to the desired device. On the other hand, if there is work that you can not do just by operating the remote control near the desired device, for example, to find the desired video tape, replace some video tapes with VTR and the contents on the TV Recording device, such as a DVD recorder or a video recorder mounted on a hard disk, that can be used to start recording from a desired position on a desired video tape while playing back and confirming, or to record image data or video camcorder video shot with a digital camera. For cable connection work such as dubbing to However, in Patent Document 1, the supervisor and the remote control are described as being connected by wire, so actions within the range of the remote control cable length are held by the remote control at the controlled device. Although it can be installed, etc., it is dangerous to hook a foot if a cable of that length is usually on the floor, and it is dangerous to fix the cable so that it does not get caught or cover it with a cover. The wireless method is preferable, as disclosed in the document that “it is possible to use not only wired but also radio and infrared” because there is an inconvenience that operation cannot be performed without going to the place.

  However, the radio wave system is a small device that can send and receive digital data, such as Bluetooth, but it increases costs, so the infrared system can be cheap and small, and it is optimal for these controls. Remote control operation with directing infrared light becomes a troublesome work because the direction is changed one by one depending on the installation position relationship between the controlled device and the supervisor.

  Similarly, in Patent Document 2, an operation screen is displayed on a display of an electronic device serving as a main control device or a display provided in a remote control that gives an instruction to the main control device, and a desired electronic device is remotely operated. To control each desired device without changing the place of operation, there is no need to change to a remote controller dedicated to the desired device. On the other hand, one key switch with the remote control is as many as the controlled device. It takes a lot of effort to remember it, and even if you remember it, you will forget the function of the controlled device that you will not use for a while, and the function display of each controlled device will be displayed on the remote control key. It is not a translation, but rather annoying.

  For this reason, it has been proposed to display each key function display of the remote control corresponding to the controlled device on the TV screen each time and operate the key with reference to it, but the key position of the desired function on the TV screen It is necessary to find and press the key at the corresponding position.

  In addition, the remote control has a large display device and receives key function information corresponding to each controlled device and proposes to display the key as an icon, but a large display is required and the remote control needs a transmission / reception function. It becomes a costly remote control. In addition, if there is work that cannot be performed by remote control only by going near the desired device, for example, to search for the desired video tape, while switching some video tapes to VTR and playing back the contents on the TV To start the recording from the desired position on the desired video tape, or to dubb the image data taken by the digital camera or the video camcorder video to a recording device such as a DVD recorder or a hard disk recording device. For cable connection work, go to these controlled devices and work, then return to the place where you can see the TV screen and move to the next remote control operation while watching the menu display on the TV screen, or as described above. Although there is a controlled device before the remote control, point the remote control to the main controlling device in the wrong direction and Remote control to display the operation screen to take, not must issue a control instruction, troublesome work was not solved.

  Therefore, an object of the present invention is to provide a system that is easy on the operator by, for example, operating the display screen of the controlled device as appropriate because the screen operation when viewing only a large CRT screen from near is not good for the eyes. There is to do.

It is an eject button for taking out.

  FIG. 7 is a diagram showing a procedure for setting the ID of the data recording apparatus 10 and the remote control ID for limiting the remote control capable of controlling the device 10 and will be described together with the flowchart of FIG.

  First, the main body setting key 502 of the remote controller 50 is pressed so that an instruction from the remote controller can be received by a device having the same custom code. That is, when the host ID number 532 and the remote control ID number 533 of the remote control transmission data code (see FIG. 3) are 99, the device with the custom code 531 matches the program on the controlled device side during manufacture so that the remote control signal is accepted. This can be realized by incorporating (not shown).

As described above, the remote controller 50 sets “08” as the control target device ID and “01” as its remote controller ID number in advance. The number 532 and the remote control ID number are changed to “99” and transmitted, and the data recording apparatus 10 receives the infrared signal at the remote control I / F unit 17 (step S1 in FIG. 8). The remote control I / F unit 17 converts the received signal into an electric signal and sends it to the main controller 13 to determine the host ID number 532. If (Step S2) 99, the remote control I / F unit 17 determines whether the custom code matches (Step S3). If they do not coincide with each other in step S3, it is determined that it is not a remote control instruction to itself, and the processing is terminated without doing anything (step S10). If they match at step S3, an operation is performed in accordance with the command instruction of the data portion 535 at step S4.
Next, it is determined in step S8 whether the remote control code has come via the network (FIG. 190) or whether it is an infrared signal input directly to the remote control I / F unit 17. Since the signal comes from the remote control I / F unit 17, as a response process to the command, the display data for the liquid crystal display unit is output from the main controller 13, and the output switching means is controlled by the control signal line 19, as shown in FIG. A menu display is displayed on the display unit 14 (step S8), and the process ends.

  In the case of via the network, the video output from the main controller 13 is output by controlling the output switching means 15 by the control signal line 19 (step S9), and the process is terminated.

  When both the infrared input and the input via the network are input, the television output is performed in step S11, and the output process to the liquid crystal display unit is performed in step S12.

  When the menu key 510 is pressed to display the screen of FIG. 7a and then the “4” key of the remote controller 50 is pressed, the screen proceeds to the screen of FIG. 7b in the same processing flow of FIG. . When the “1” key on the remote controller 50 is pressed, the screen advances to the main body ID input screen (FIG. 7 c). Here, the “0” key and “8” key are pressed on the remote controller 50 and then the “OK” key 505 is pressed. As a result, the processing flow of the main body proceeds to step S1, step S2, step S3, and step S4, data "08" is stored in the host ID storage register (not shown) of the main controller 13, and the ID setting of the main body is set. end.

  7b, if the "2" key is pressed, the screen proceeds to the screen of FIG. 7e and an ID input screen for specifying a remote control capable of controlling the data recording apparatus 10 is displayed. When the key, “1” key, and enter key 505 are pressed, the remote controller ID is stored in a remote controller ID storage register (not shown) of the main controller 13 as described above.

  When the host ID number is not 99 in step S2, it is determined in step S5 whether it matches the host number stored in the host ID storage register (not shown) of the main controller 13, and in step S6, the same as the remote control ID number. It is determined whether or not they match, and if they match, the command of the data portion 535 is processed in step S4. If they do not match in step S5, it is determined in step S13 that the command came from an infrared signal. If yes, a remote control signal is sent to another electronic device connected to the network via the data recording device 10. Therefore, in step S14, a header is added to the host ID number, remote control ID number, and command data, and the data is transmitted from the network I / F 11. If it is command data that came through the network, it will skip to No and will end without processing anything without being transferred.

  Even if they match (Yes) in step S5, if they do not match in step S6, nothing is processed and the process ends (step S10).

  With such a mechanism, only the remote controller 50 and the data recording apparatus 10 having the same host ID and remote controller ID set to each other can be controlled by remote control operation.

  FIGS. 9-1 and 9-2 illustrate the operation of setting the ID of the television 60 while watching the television screen, and the remote control operation of the data recording apparatus 10 via the remote control light receiving unit 69 of the television 60 via the network. The operation will be described with reference to the flowchart of the television 60 in FIG.

  FIG. 10 is a diagram for explaining the operation processing flow of the television 60. For example, when the menu button 510 of the remote controller 50 is pressed toward the television 60, the remote controller light receiving unit 69 receives the light (step S30). It is determined whether the number 532 is 99. If Yes, it is determined in step S32 whether the custom codes match. If Yse, the TV operation command of data 535 is processed, and a menu display corresponding to the TV operation command is displayed on the display unit 65 ( Step S33), the process is terminated. If No in step S32, the process ends without doing anything (step S35).

On the other hand, if the host ID number is not 99, it is determined in step S34 whether the host ID number matches the number stored in the host ID register (not shown) of the main controller of the television 60. The TV operation command is processed in step S33. If they do not match, it is determined in step S36 whether the signal data is an infrared signal, and if yes, step S37 is used to send a remote control signal via TV 60 to another electronic device connected to the network. Then, a header is added to the host ID number, remote control ID number, and command data, and the data is transmitted from the network I / F 61. If No, exit without processing anything.
After step S34, the remote control ID number match confirmation is not performed so that the TV can be operated by a plurality of remote controls. If the remote control is limited, a remote control ID number match confirmation step may be inserted. .

  The registration procedure for the ID number of the television 60 may be the same as that of the data recording device 10, and the operation instruction command from the remote controller 50 is set in the main body of the remote controller in the flow of steps S30, S31, S33, and S35. After the key operation of the key 502, when the menu key 510 is pressed, the screen shown in FIG. 9-1a is displayed. Then, when the “4” key of the remote controller 50 is pressed, the main unit setting screen is displayed (FIG. 9-2b). Press the “1” key to move to the main unit ID setting screen.

  Here, in order to register “06” (may be any numerical value) as the ID number of the television 60, the host ID register of the main controller 68 is pressed by pressing the “0” key, the “6” key, and the decision key 505. “06” is stored in (not shown).

  In the TV 60 operating in this way, when the menu button 510 of the remote controller 50 is pressed toward the TV 60, the TV 60 receives an infrared signal by the remote controller light receiving unit 69 (step S30), and the host ID number of the remote controller in step S31. Check out. As described above, since the host number “08” and the remote controller ID number “01” are sent from the remote controller, the answer is No, and in step S34, it is compared with the TV ID number. Since the ID number of the TV 60 is “06”, it is inconsistent and it is determined that the signal is an infrared light signal (step S36). Sent from network I / F 61.

  A signal from this network is received by the data recording device 10, and in the flow process of FIG. 8, the host number “08” and the remote control ID number “01” are used, so that the process proceeds to step S1, step S2, and step S5. Since the number and the remote control ID number match, processing corresponding to the menu command is performed in step S4, the signal from the network (LAN) is determined in step S7, and a video signal is output for television display in step S9, via the video cable 71. The video signal is input to a video input terminal (not shown) of the television 60, and the video signal is displayed on the display unit 65 as the menu screen of FIG. 9-2e.

  Similarly, the key operation of the remote controller 50 is transmitted to the data recording device 10 via the remote control light receiving unit of the television and displayed on the television screen. For example, in order to instruct the storage of data in the memory card 40, the “1” key operation of the remote controller 50 is used to advance to the screen of FIG. 9-2f, and the memory card is selected by pressing the “1” key and the “OK” key 505. In order to designate the removable hard disk (iVDR) as the storage destination, the “6” key and the “OK” key 505 are pressed to complete the operation of saving the data in the memory card 40 to the removable hard disk (iVDR) (FIG. 9-). 2g).

  In the data reproduction, the data reproduction screen is displayed by pressing the “2” key from the state shown in FIG. 9-2e (FIG. 9-2h), and the recording data of the removable hard disk (iVDR) is classified, for example, by pressing the “4” key. The playback screen is displayed (FIG. 9-2i). Subsequently, by pressing the “1” key, each data of the travel genre is displayed as, for example, a thumbnail (FIG. 9-2j), and a numerical key (eg, “5” key) of a desired thumbnail number is pressed to go to Oze for a trip. It can be operated so that individual photo data can be viewed.

<Second Embodiment>
FIG. 12 is a diagram showing a network configuration according to the second embodiment of the present invention. The output of the data recording apparatus 10 to the television is not connected to the television by a video signal, but sent via the network. The same thing as 1 embodiment attaches | subjects the same number, and demonstrates.
