When information is exchanged via the short-range wireless communication interface, processing is executed based on the profile information.
[0031]
FIG. 7 is a block diagram illustrating a detailed configuration example of the VCR 30.
[0032]
The CPU 37, the display unit 31, the encoder 33, the decoder 34, the HDD 35, the RAM 36, the light receiving unit 38, the short-range wireless interface 39, the non-contact IC device 40, the recording / reproducing unit 41, and the drive 90 are mutually connected via the internal bus 42. It is connected.
[0033]
The CPU 37 outputs data reproduced by the recording / reproducing unit 41 from the magnetic tape of the attached video cassette to the encoder 33 via the internal bus 42. The encoder 33 encodes the reproduction data and outputs it to the short-range wireless communication interface 39. Further, the CPU 37 causes the data recorded in the HDD 35 or RAM 36 to be read based on a user instruction and displayed on the display unit 31. A signal corresponding to a user instruction is output from the light emitting unit 81 of the remote controller 80, the light emitting unit 68 of the PDA 60 (FIG. 9), or the short-range wireless communication interface 66, and is captured from the light receiving unit 38 or the short-range wireless interface 39. It is.
[0034]
The HDD 35 records profile information such as an ID unique to the VCR 30 and a URL to be accessed. The CPU 37 reads the profile information unique to the VCR 30 from the HDD 35 and then approaches it via the non-contact IC device 40. Sent to the electronic device and recorded. In addition, the profile information of the electronic device that is brought close is received via the non-contact IC device 40 and stored in the RAM 36.
[0035]
  The internal bus 42 is connected to the drive 90 as necessary, reads the control program stored in the magnetic disk 101, the optical disk 102, the magneto-optical disk 103, or the semiconductor memory 104, and loads the read control program to the HDD 35. Supply and record.
  FigureFIG. 8 is a block diagram illustrating a detailed configuration example of the PDA 60.
[0036]
The display unit 61, the decoder 62, the semiconductor memory 63, the RAM 64, the CPU 65, the short-range wireless communication interface 66, the non-contact IC device 67, the light emitting unit 68, and the drive 110 are connected to each other via an internal bus 69.
[0037]
When the user operates the operation icon displayed on the display unit 61, the CPU 65 controls the light emitting unit 68 or the short-range wireless communication interface 66 and outputs a signal based on the user's operation to a target electronic device.
[0038]
The CPU 65 outputs information recorded in the RAM 64 or the semiconductor memory (for example, Memory Stick (trademark)) 63 to the short-range wireless communication interface 66 or the non-contact IC device 67 based on a user instruction.
[0039]
The CPU 65 also reads out data recorded in the semiconductor memory 63 or the RAM 64 based on a user instruction, and outputs the data to the display unit 61 for display.
[0040]
The short-range wireless communication interface 66 captures data via the short-range wireless communication interface of another electronic device. The fetched data is supplied to the decoder 62 by the CPU 65 via the internal bus 69. The decoder 62 decodes the supplied data and outputs it to the display unit 61 via the internal bus 69 for display.
[0041]
The non-contact IC device 67 outputs ID information unique to the PDA 60 recorded in advance in the semiconductor memory 63 and profile information such as a URL to be accessed to the electronic device to be authenticated, and records profile information unique to the electronic device to be authenticated. By doing so, mutual authentication processing is performed.
[0042]
In addition, when the mutual authentication process is performed between the PDA 60 and the television receiver 20 after the mutual authentication process is performed between the PDA 60 and the television receiver 20, profile information unique to the PDA 60 and the television receiver 20 is recorded in the VCR 30. The Furthermore, when the mutual authentication process between the PDA 60 and the television receiver 20 is performed again, profile information unique to the VCR 30 is recorded in the television receiver 20.
[0043]
The internal bus 69 is connected to the drive 110 as necessary, reads the control program stored in the magnetic disk 121, the optical disk 122, the magneto-optical disk 123, or the semiconductor memory 124, and reads the read control program into the semiconductor memory. 63 to be recorded.
[0044]
Next, a password registration process in the television receiver 20 will be described with reference to FIG. By registering a password when purchasing the television receiver 20 (at the start of use), it is possible to confirm that the user performing authentication is the owner of the television receiver 20 in the mutual authentication process. . When the main power of the television receiver is turned off, the stored password is deleted. Thus, in the case of disposal or recycling, since the password of the television receiver is not known, it is prevented from becoming unusable. This process is started when the user turns on the main power by operating the remote controller 80 attached to the television receiver 20.
[0045]
In step S <b> 11, when the previous authentication information is recorded in the RAM 22, the CPU 6 initializes the authentication information (deletes the authentication information). When the main power is turned off, deleting the authentication information recorded so far makes it impossible to use it by re-registering even if the user forgets the password. Is prevented.
[0046]
In step S <b> 12, the CPU 6 displays a password input screen on the display unit 5 via the internal bus 9. A display example of the display unit 5 in this processing is shown in FIG. In this example, the message “Please enter your password” is displayed. The user operates the remote controller 80 according to this message and inputs a password. At this time, the operation detection unit 83 detects the operation and outputs a signal corresponding to the operation to the control unit 82. The control unit 82 causes the light emitting unit 81 to emit an infrared signal corresponding to the input. The emitted infrared signal is received by the light receiving unit 7 of the television receiver 20. The CPU 6 acquires password information (for example, a 4-digit number) from the output of the light receiving unit 7.
[0047]
In step S13, the CPU 6 determines whether or not the input password information is correctly input (whether it is within the range of the number of digits and the determined character). If it is determined that the password has not been input correctly, in step S14, the CPU 6 displays an error message (for example, a message such as “password is a 4-digit number”) on the display unit 5. Thereafter, the process returns to step S12, and the subsequent processing is repeated.
[0048]
If it is determined in step S13 that the password has been correctly input, the process proceeds to step 15 where the CPU 6 causes the RAM 22 to record the input password.
[0049]
The above processing is executed in the same manner also in all electronic devices such as the VCR 30 and the PDA 60 that constitute the wireless network (home network). The password of each device may be the same or different. As described above, in all electronic devices, by setting the password when the main power is turned on, it is possible to avoid a trouble that the device is illegally used by another user (a user who does not know the password).
[0050]
Next, an authentication information registration process in the VCR 30 and the PDA 60 will be described with reference to FIG. 11 and FIG. This process is performed after the password is set and registered in the VCR 30 and the PDA 60, and is started when the user brings the PDA 60 close to the VCR 30.
[0051]
First, an authentication information registration process in the VCR 30 will be described with reference to FIG. When the PDA 60 is brought close to the VCR 30 by the user's operation, the non-contact IC device 40 detects that the non-contact IC device 67 is arranged in the vicinity (for example, a distance of several centimeters) and outputs the detection signal to the CPU 37. To do. At this time, the CPU 37 sets an authentication mode in step S31.
[0052]
In step S <b> 32, the CPU 37 causes the non-contact IC device 40 to output a signal requesting transmission of profile information unique to the PDA 60 via the internal bus 42.
[0053]
Based on this request, the non-contact IC device 67 of the PDA 60 transmits the profile information (step S63 in FIG. 12 described later). Therefore, in step S <b> 33, the non-contact IC device 40 receives profile information transmitted from the PDA 60 and supplies it to the CPU 37. The profile information includes information such as an ID unique to the PDA 60 and a URL to be accessed. The profile information is described in XML (eXtensible Markup Language) to ensure interoperability.
[0054]
In step S34, the CPU 37 determines whether or not the received profile information is appropriate (whether the profile information is not damaged or has been correctly received). If it is determined that the profile information is not appropriate, the CPU 37 notifies the PDA 60 of an error via the non-contact IC device 40 in step S35. In step S36, the CPU 37 ends the process.
[0055]
If it is determined in step S34 that the profile information is appropriate, the process proceeds to step S37, and the CPU 37 stores the profile information of the PDA 60 in the RAM 36. At this time, the profile information of the PDA 60 is erased when the power is turned off to be recorded in the RAM 36. This is in consideration of the case of discard, as with the password information described above.
[0056]
In step S <b> 38, the CPU 37 transmits an OK notification indicating that the profile information has been properly stored to the PDA 60 via the non-contact IC device 40.
[0057]
In step S <b> 39, the CPU 37 reads the profile information of the VCR 30 recorded in the HDD 35 and transmits it to the PDA 60 via the non-contact IC device 40. In this case, when there is another device that has already undergone the mutual authentication process in the VCR 30 (when profile information of the other device that has undergone the mutual authentication process is recorded in the RAM 36), the CPU 37 determines the profile of the other device. Also send information. The profile information of the VCR 30 is recorded in advance in the HDD 35, and is not erased even when the power is turned off.
[0058]
When profile information is transmitted to the PDA 60, an error (step S69 in FIG. 12 described later) or an OK notification (step S72 in FIG. 12 described later) is transmitted from the PDA 60. Therefore, in step S <b> 40, the CPU 37 determines whether an error notification is received from the PDA 60 via the non-contact IC device 40. If an error notification is received, the CPU 37 ends the process in step S41.
[0059]
In step S40, if the CPU 37 determines that no error notification has been received, the process proceeds to step S42, and the OK notification from the PDA 60 is received via the non-contact IC device 40.
[0060]
In step S43, the CPU 37 causes the display unit 31 to display a password input screen. The user operates a dedicated remote controller (or PDA 60) (not shown) according to this display and inputs a password (required for using the VCR 30) set in the VCR 30. The CPU 37 acquires the password input at this time.
[0061]
In step S44, the CPU 37 determines whether or not the input password is appropriate (whether or not it is the same as the password registered and registered in the RAM 36 when the main power is turned on). If it is determined that the password is not appropriate, the CPU 37 notifies the PDA 60 of an error via the non-contact IC device 40 in step S45. In step S46, the CPU 37 ends the process.
[0062]
If it is determined in step S <b> 44 that the password is appropriate, the CPU 37 transmits an OK notification to the PDA 60 via the non-contact IC device 40. This OK notification notifies the PDA 60 that the password is appropriate.
[0063]
  The user similarly inputs a password to the PDA 60. At this time, an error (step S78 in FIG. 12 to be described later) or OK notification (step S in FIG. 12 to be described later) from the PDA 60.80) Is sent. Therefore, in step S <b> 48, the CPU 37 determines whether an error notification has been received from the PDA 60 via the non-contact IC device 40. If it is determined that an error notification has been received, in step S49, the CPU 37 ends the process.
[0064]
If it is determined in step S48 that no error notification has been received, the process proceeds to step S50, and the CPU 37 receives an OK notification from the PDA 60 via the non-contact IC device 40. This OK notification is for the VCR 30 to confirm that the password input to the PDA 60 is appropriate.
[0065]
Next, an authentication information registration process in the PDA 60 executed in correspondence with the authentication information registration process of the VCR 30 in FIG. 11 will be described with reference to FIG. When the PDA 60 is brought close to the VCR 30 by a user operation, the non-contact IC device 67 detects that the non-contact IC device 40 is arranged in the vicinity. When this detection signal is input, in step S61, the CPU 37 sets an authentication mode.
[0066]
In step S62, the CPU 65 receives a profile information transmission request (step S32) from the VCR 30 from the non-contact IC device 67 via the internal bus 69.
[0067]
In step S 63, the CPU 65 reads the profile information such as the ID unique to the PDA 60 and the URL to be accessed, which is recorded in advance in the semiconductor memory 63, and transmits it to the VCR 30 via the non-contact IC device 67. As described above, this profile information is acquired by the VCR 30 in step S33. When there is another device that has already undergone mutual authentication processing in the PDA 60 (when profile information of another device that has undergone mutual authentication processing is recorded in the RAM 64), the CPU 65 also displays profile information of this other device. Send. The profile information unique to the PDA 60 is recorded in advance in the semiconductor memory 63, and is not erased even when the power is turned off.
[0068]
In step S <b> 64, the CPU 65 determines whether an error notification (notification transmitted in the process of step S <b> 35) has been received from the VCR 30 via the non-contact IC device 67. If an error notification is received, the CPU 65 ends the process in step S65.
[0069]
If it is determined in step S64 that the error notification has not been received, the CPU 65 proceeds to step S66 and sends an OK notification from the VCR 30 (the notification transmitted in the process of step SS38) via the non-contact IC device 67. receive. This OK notification notifies the VCR 30 that the profile information of the PDA 60 has been properly stored in the RAM 36 of the VCR 30.
[0070]
In step S67, the non-contact IC device 67 receives the profile information from the VCR 30 (profile information transmitted in the process of step S39). At this time, the received profile information includes information such as an ID unique to the VCR 30 and a URL to be accessed. In addition, profile information of other devices mutually authenticated by the VCR 30 is also included.
[0071]
In step S68, the CPU 65 determines whether the received profile information is appropriate (whether the profile information is not damaged or has been correctly received). If it is determined that it is not appropriate, the CPU 65 notifies the VCR 30 of an error via the non-contact IC device 67 in step S69. In step S70, the CPU 65 ends the process.
[0072]
If it is determined in step S68 that the profile information is appropriate, the process proceeds to step S71, and the CPU 65 stores the profile information in the VCR 30 in the RAM 64.
[0073]
In step S <b> 72, the CPU 65 causes the VCR 30 to transmit an OK notification via the non-contact IC device 67. This OK notification notifies the PDA 60 that the VCR 30 profile information has been saved.
[0074]
In step S <b> 73, the CPU 65 determines whether or not an error notification (notification transmitted in the process of step S <b> 45) has been received from the VCR 30 via the non-contact IC device 67. If it is determined that an error notification has been received, the CPU 65 ends the process in step S74.

If it is determined in step S73 that an error notification has not been received, the process advances to step S75, and the CPU 65 sends an OK notification from the VCR 30 via the non-contact IC device 67 (the notification transmitted in the process of step S47). receive. This OK notification is for the PDA 60 to confirm that the password is proper in the VCR 30.
[0076]
  In step S76, the CPU 65 displays a password input screen on the display unit 61, and prompts the user to set the password registered in the PDA 60 (PDA 60).TheEnter the password required for use. Based on this input screen, the user operates the display unit 61 (touch panel) to input the password of the PDA 60. The CPU 65 acquires this input password.
[0077]
  In step S77, the CPU 65 determines whether or not the input password is appropriate (the setting is registered in the RAM 64 when the main power is turned on).HaveWhether it is the same as the password). If it is determined that the input password is not appropriate, the CPU 65 notifies the VCR 30 of an error via the non-contact IC device 67 in step S78. In step S79, the CPU 65 ends the process.
[0078]
If it is determined in step S77 that the password is appropriate, the process proceeds to step S80, and the CPU 65 transmits an OK notification to the VCR 30 via the non-contact IC device 67. This OK notification is for notifying the VCR 30 that the password is proper in the PDA 60, and is received by the VCR 30 in step S50.
[0079]
11 and 12, authentication information registration processing is performed between the VCR 30 and the PDA 60. The VCR 30 includes profile information unique to the PDA 60 and profile information of other devices that the PDA 60 mutually authenticates. Also, the PDA 60 records profile information unique to the VCR 30 and profile information of other devices mutually authenticated by the VCR 30. By performing the mutual authentication information registration, the PDA 60 can serve as a remote controller for the VCR 30. Specifically, based on the user's command, the CPU 65 of the PDA 60 transmits a signal based on the user's command to the short-range wireless communication interface 39 of the VCR 30 via the short-range wireless communication interface 66. The CPU 37 of the VCR 30 controls each unit based on the signal received via the short-range wireless communication interface 39 and executes processing based on the command.
[0080]
The authentication information registration process as shown in FIGS. 11 and 12 is similarly performed between the PDA 60 and the television receiver 20. Furthermore, when authentication information registration processing is performed between the PDA 60 and the television receiver 20 after the authentication information registration processing is performed between the PDA 60 and the VCR 30, the PDA 60 contains authentication information unique to the VCR 30. In the television receiver 20, two pieces of authentication information of the PDA 60 and the VCR 30 are registered. Further, also in the PDA 60, authentication information of the VCR 30 and the television receiver 20 is registered. Further, after this processing, the PDA 60 and the VCR 30 are brought closer again, whereby new authentication information unique to the television receiver 20 included in the authentication information of the PDA 60 is recorded in the VCR 30.
[0081]
  By performing such processing, mutual authentication processing between them can be performed via the small and lightweight PDA 60 without moving relatively large and heavy electronic devices such as the television receiver 20 and the VCR 30. Can be done. Mutual authentication process completedeachThe devices constitute a wireless network, communicate with each other using their respective short-range wireless communication interfaces, and one can control the other.
[0082]
  Next, processing for operating the television receiver 20 with the PDA 60 will be described with reference to FIGS. 13 and 14. In this process, the user operates the PDA 60 and the PDA 60InTriggered when a list of registered authenticated devices is requested.
[0083]
First, the processing of the PDA 60 will be described with reference to FIG.
[0084]
In step S91, based on a command from the user, the CPU 65 reads information on the authenticated device (device registered as a device constituting the wireless network) from the RAM 64 and causes the display unit 61 to display the information. An example of the display screen at this time is shown in FIG. In the example of FIG. 15, a list of authenticated devices is displayed on the display unit 61. In this example, since the video deck (VCR 30) and the television (television receiver 20) are registered, the user can select one of them.
[0085]
In step S92, the CPU 65 accepts a selection based on a user command.
[0086]
In step S93, the CPU 65 searches the RAM 64 for profile information of the device (for example, the television receiver 20) selected by the user.
[0087]
In step S94, the CPU 65 reads the URL of the device from the profile information of the selected device recorded in the RAM 64, accesses the URL of the device via the short-range wireless communication interface 66, and also accesses the PDA 60 from the semiconductor memory 63. The unique ID information is read and transmitted.
[0088]
When ID information unique to the PDA 60 is transmitted to the television receiver 20, an error (step S113 in FIG. 14 described later) or a URL file (step S115 in FIG. 14 described later) is transmitted from the television receiver 20. It will be. Therefore, in step S95, the CPU 65 determines whether or not an error notification has been received via the short-range wireless communication interface 66. For example, if the television receiver 20 accessed by the PDA 60 is not authenticated, an error notification is received. If it is determined that an error notification has been received, the CPU 65 ends the process in step S96.
[0089]
If it is determined in step S95 that no error notification has been received, the process advances to step S97, and the CPU 65 receives the accessed URL file via the short-range wireless communication interface 66 and causes the display unit 61 to display it. An example of the display screen at this time is shown in FIG. In the example of FIG. 16, a list of operation selection screens for the television receiver 20 is displayed on the display unit 61. In this example, since channel operation, screen operation, reservation, and input switching are displayed, the user can select any one of them.
[0090]
In step S98, the CPU 65 accepts a selection based on a user command.
[0091]
In step S99, the CPU 65 outputs a signal corresponding to the command (for example, a signal corresponding to the channel operation) to the television receiver 20 via the short-range wireless communication interface 66.
[0092]
Next, with reference to FIG. 14, the process of the television receiver 20 executed corresponding to the process of the PDA 60 of FIG. 13 will be described.
[0093]
In step S111, when the CPU 6 of the television receiver 20 receives the ID information specific to the PDA 60 (ID information transmitted in the process of step S94) via the short-range wireless communication interface 23, the RAM 22 in step S112. The authentication information recorded in is read out and it is determined whether or not the accessed PDA 60 has been authenticated. If it is determined that authentication has not been completed, the CPU 6 notifies the PDA 60 of an error via the short-range wireless communication interface 23 in step S113. In step S114, the CPU 6 ends the process.
[0094]
If it is determined in step 112 that the accessed PDA 60 has been authenticated, the process proceeds to step S115, and the CPU 6 uses XML (or HTML (Hyper Text Markup Language) file) using CGI (Common Gateway Interface). And is transmitted as a URL file accessed by the PDA 60.
[0095]
In step S <b> 116, the CPU 6 receives a signal corresponding to the command input by the user (the signal output in the process of step S <b> 99) from the PDA 60 via the short-range wireless communication interface 23. The CPU 6 activates the CGI based on the input signal and executes a process corresponding to the input signal.
[0096]
  By repeating such processing, a display corresponding to the processing is performed on the display unit 61 of the PDA 60. For example, when the user selects “channel operation” on the display unit 61 in FIG. 16, the short-range wireless communication interface 66 transmits a signal corresponding to the operation to the television receiver 20. Then a television receiver20When the program of the corresponding channel transmitted from is received, the CPU 65 causes the display unit 61 to display the program.
[0097]
Next, with reference to FIG. 17 and FIG. 18, a process of playing back a recorded TV program of the VCR 30 on the PDA 60 will be described. This process is started when the user operates the PDA 60 to request the display of the authenticated device list in the PDA 60.
[0098]
First, the processing of the PDA 60 will be described with reference to FIG.
[0099]
In step S <b> 121, based on the operation from the user, the CPU 65 reads out information on the authenticated device from the RAM 64 and displays it on the display unit 61. At this time, a list of authenticated devices is displayed on the display unit 61 as shown in FIG.
[0100]
In step S122, the CPU 65 accepts a selection based on a user instruction.
[0101]
In step S123, the CPU 65 searches the RAM 64 for profile information of the selected device (for example, the VCR 30).
[0102]
In step S124, the CPU 65 reads the URL of the device from the profile information of the selected device recorded in the RAM 64, accesses the URL of the device via the short-range wireless communication interface 66, and transfers the URL of the device from the semiconductor memory 63 to the PDA 60. The unique ID information is read and transmitted.
[0103]
When ID information unique to the PDA 60 is transmitted to the VCR 30, an error (step S153 in FIG. 18 described later) or a URL file (step S155 in FIG. 18 described later) is transmitted from the VCR 30. Therefore, in step S125, the CPU 65 determines whether or not an error notification has been received via the short-range wireless communication interface 66. For example, if the VCR 30 accessed by the PDA 60 is not authenticated, an error notification is received. If it is determined that an error notification has been received, the CPU 65 ends the process in step S126.
[0104]
If it is determined in step S125 that no error notification has been received, the process advances to step S127, and the CPU 65 receives the accessed URL file via the short-range wireless communication interface 66 and causes the display unit 61 to display the file. An example of the display screen at this time is shown in FIG. In the example of FIG. 19, a list of operation selection screens for the VCR 30 is displayed on the display unit 61. In this example, a recording reservation, a recorded program list, and other settings are displayed, and the user can select any of them.
[0105]
  In step S128, the CPU 65 accepts a selection based on a user operation. In this case, select “List of recorded programs”ButAccepted.
[0106]
In step S129, the CPU 65 transmits a signal corresponding to the operation to the VCR 30 via the short-range wireless communication interface 66.
[0107]
When a signal corresponding to the operation is transmitted to the VCR 30, an error (step S158 in FIG. 18) or a URL file (step S160 in FIG. 18) is transmitted from the VCR 30. Therefore, in step S130, the CPU 65 determines whether or not an error notification has been received from the VCR 30 via the short-range wireless communication interface 66. If it is determined that an error notification has been received, the process proceeds to step S131, and the CPU 65 ends the process.
[0108]
If it is determined in step S130 that an error notification has not been received, the process proceeds to step S132, and the CPU 65 receives the URL file transmitted from the VCR 30 via the short-range wireless communication interface 66, and displays the display unit. 61 is displayed. An example of the display screen at this time is shown in FIG. In the example of FIG. 20, the titles of programs such as sports news, afternoon news, and morning drama are displayed on the display unit 61 as a list of recorded programs. The user can select a program from these.
[0109]
In step S <b> 133, the CPU 65 accepts selection of “afternoon news” in accordance with a user instruction.
[0110]
In step S134, the CPU 65 causes the short-range wireless communication interface 66 to transmit a signal corresponding to the user's instruction (in this case, selection of “afternoon news”).
[0111]
  When a signal corresponding to the operation is transmitted to the VCR 30, image data and audio data of “afternoon news” are transmitted from the VCR 30. Therefore, in step S135, the CPU 65 sends the image data and audio data of “afternoon news” from the VCR 30 to the short-range wireless communication interface.66And display an image on the display unit 61, and output a corresponding sound from a speaker (not shown). An example of the display screen at this time is shown in FIG. In the display unit 61 of FIG. 21, an image of “afternoon news” is displayed.
[0112]
Next, the processing of the VCR 30 executed in correspondence with the processing of the PDA 60 of FIG. 17 will be described with reference to FIG.
[0113]
In step S151, the CPU 37 of the VCR 30 receives ID information unique to the PDA 60 (ID information transmitted in the process of step S124) via the short-range wireless communication interface 39.
[0114]
In step S152, the CPU 37 reads the authentication information recorded in the RAM 36, and determines whether or not the accessed PDA 60 has been authenticated. If it is determined that the authentication has not been completed, the CPU 37 notifies the PDA 60 of an error via the short-range wireless communication interface 39 in step S153. In step S154, the CPU 37 ends the process.
[0115]
  If it is determined in step 152 that the accessed PDA 60 has been authenticated, the process proceeds to step S155, and the CPU37Uses CGI to create an XML (or HTML) file and transmits it as a URL file accessed by the PDA 60.
[0116]
In step S156, the CPU 37 receives a signal corresponding to the operation input by the user (the signal output in the process of step S129) from the PDA 60 via the short-range wireless communication interface 39. The CPU 37 activates the CGI based on the input signal and executes processing corresponding to the input signal. In this example, the CPU 37 receives a signal corresponding to the selection of “recorded program list” from the PDA 60 and activates the CGI.
[0117]
In step S157, the CPU 37 reads information about the program recorded in the recording / playback unit 41, and determines whether there is a recorded program. If it is determined that there is no recorded program, the CPU 37 notifies the PDA 60 of an error via the short-range wireless communication interface 39 in step S158. In step S154, the CPU 37 ends the process.
[0118]
If it is determined in step S157 that there is a recorded program, the process proceeds to step S160, where the CPU 37 activates the CGI, creates an HTML (XML) file for the recorded program information, and uses the short-range wireless as the accessed URL file. The data is transmitted to the PDA 60 via the communication interface 39.
[0119]
In step S161, the CPU 37 sends a signal (signal output in the process of step S134) corresponding to an operation (selection of “afternoon news”) input by the user via the short-range wireless communication interface 39 from the PDA 60. Receive. The CPU 37 activates the CGI from the HDD 35 based on the input signal.
[0120]
In step S162, the CPU 37 determines the signal corresponding to the operation input by the user (selection of “afternoon news”) and the ID information of the accessed device (the ID unique to the accessed device received in step S151). ), The encoding method that can be decoded by the device and the display capability of the display unit 61 are confirmed, the data of “afternoon news” is read from the recording / reproducing unit 41, and is encoded by the encoder 33. When the encoder 33 finishes encoding the “afternoon news” data, the CPU 37 transmits the data to the PDA 60 via the short-range wireless communication interface 39.
[0121]
By repeating such processing, a display corresponding to the processing is made on the display unit 61 of the PDA 60. In addition, information such as a recorded program recorded in the VCR 30 can be reproduced by the television receiver 20 using the PDA 60 as a remote controller. In this case, the CPU 6 of the television receiver 20 can operate the VCR 30 by accessing the URL of the VCR 30 via the short-range wireless communication interface 23. The operation at this time can also be performed by the remote controller 80.
[0122]
As described above, by providing the short-range wireless communication interface and the non-contact IC device in the television receiver 20, VCR 30, and PDA 60, a home network can be easily constructed.
[0123]
In addition, for example, if a mobile phone is registered so as to constitute a wireless network, the user can access the URL of the video at home from the outside by using the mobile phone, and can easily watch the recorded program. It becomes possible.
[0124]
Furthermore, a pay program can be recorded on the VCR 30 and reproduced on the go. In this case, the program providing side, for example, restricts the number and the number of devices that can view the program, and distributes a paid program of satellite broadcasting. By restricting access to the specified URL, unauthorized copying or the like can be prevented.
[0125]
Further, since the technology of the non-contact IC card is based, it is possible to perform a mutual authentication process with high security and easy.
[0126]
Note that electronic devices constituting the wireless network include television receivers, VCRs, PDAs, mobile phones, audio devices, tuners, printers, portable audio playback devices represented by Walkman (trademark), refrigerators, coolers. Various household electronic devices can be employed.
[0127]
The series of processes described above can be executed by hardware, but can also be executed by software. When a series of processing is executed by software, a program constituting the software executes various functions by installing a computer incorporated in dedicated hardware or various programs. For example, it is installed from a recording medium in a general-purpose personal computer or the like.
