FIG. 1 is a block diagram showing a home network system to which the present invention is applied. To the IEEE 1394 serial bus 1, an IRD 2 as a control device and a CD player 3 as a controlled device controlled by the IRD 2 are connected.

 Here, an example is shown in which a CD player 3 is connected as a controlled device to the serial bus 1, but other controlled devices are also connected.

 When the CD player 3 is connected to the IEEE 1394 serial bus 1, the CD player 3 transmits a DCM (Device Control Module) and an FCM (Function Control Module) described later to the IRD 2 via the IEEE 1394 serial bus 1. . The IRD 2 detects the connection status of devices connected to the IEEE 1394 serial bus 1 from the received information, DCM and FCM, and controls the GU I (Graphical User Interface) for controlling those devices. ) Is displayed on an LCD (Liquid Crystal Display) 29 (see Fig. 2), which is a display device with a built-in).

 The user operates the touch panel 28 (see FIG. 2) attached to the IRD 2 based on the display on the LCD 29, and instructs the processing to be executed by the CD player 3 connected to the IEEE 1394 serial bus 1. . The IRD 2 generates a control signal based on a command from the user, and supplies the control signal to the CD player 3 via the IEEE 1394 serial bus 1. The CD player 3 performs, for example, processing such as reproduction of music data based on the input control signal.

IRD 2 is configured, for example, as shown in FIG. The signal transmitted from the CD player 3 is transmitted to the CP via the IEEE 1394 serial bus 1, the IEEE 1394 interface 21 and the internal bus 22. Input to U (Central Processing Unit) 23. Further, the evening touch panel 28 is operated by the user, and a command corresponding to the operation is input to the CPU 23 via the input / output interface 27 and the internal bus 22. Here, the evening touch panel 28 can be operated according to the message displayed on the LCD 29.

 In this case, the evening touch panel 28 is used for inputting an operation command. However, the present invention is not limited to the evening touch panel 28, and a keyboard or the like in which operation keys and many operation keys are arranged is used.

 CPU 23 functions as a control unit that controls the entire IRD 2. The CPU 23 reads out and executes the program stored in the ROM 24 in accordance with the input signal, and outputs the processing result to the LCD via the input / output interface 27 as necessary. 2 Output to 9 for display. The CPU 23 further generates character image data representing a message to assist the user's operation, and outputs the character image data to the LCD 29 via the internal bus 22 and the input / output interface 27 for display. Or a control signal for controlling the CD player 3 and transmitting it to the CD player 3 via the internal bus 22, the IEEE 1394 interface 21 and the IEEE 1394 serial bus 1. . The RAM 25 temporarily stores data generated by executing the program of the CPU 23 and other data necessary for the CD player 3 to execute processing.

The antenna 11 receives, for example, a signal of a satellite broadcast wave and supplies the received signal to the tuner 26 of the IRD 2. The tuner 26 receives a broadcast channel signal instructed by the CPU 23 from the received signal of the satellite broadcast wave received by the antenna 11. hard disk The (HD) 30 stores various applications executed by the CPU 23, middleware, and the like. The drive 31 includes a magnetic disk 41, an optical disk 42, a magneto-optical disk 43, or a semiconductor memory.

4 4 etc. can be attached.

 The CD player 3 which is connected to the serial bus 1 and controlled by the IRD 2 has the configuration as shown in FIG.

 The signal transmitted from IRD2 is IEEEE1394 serial bus

1, IEEE 13 94 Input to CPU 53 via interface 51 and internal bus 52. When the user operates the CD player 3 using the evening touch panel 58, a signal corresponding to the user's operation is input to the CPU 53 via the input / output interface 57 and the internal bus 52.

 Note that the operation means used to operate the CD player 3 is not limited to the touch panel 58, and operation keys and the like can be used.

 The CPU 53 provided in the CD player 3 reads out and executes the program stored in the ROM 54 based on the input signal, and, for example, sends the program to the playback processing unit 56 via the internal bus 52. Outputs control signals and: Uses its own DCM and FCM stored in OM 54 to internal bus 52, IEEE 1394 interface 51, and IEEE 1394 serial bus 1. To I RD 2 via The RAM 55 temporarily stores data generated by the execution of the CPU 53 program and data required for the CD player 3 to execute processing.

The playback processing unit 56 of the CD player 3 is input from the CPU 53 Based on the control signal, the attached media (not shown), for example, the data recorded on a CD, for example, music data, is read, and the internal bus 52, the IEEE 1394 interface 51 are read. And I EEE 1 394 Transmit to I RD 2 via serial bus 1 or output read data to built-in speaker for playback. The playback processing unit 56 also detects T〇C (Table Of Contents) data from the playback data and outputs it to the LCD 59 via the internal bus 52 and the input / output interface 57. The contents are displayed as visible information. Here, the T0C data displayed on the LCD 59 as the display device includes the total number of recording tracks formed on the CD, the total data amount of the recording tracks, and the like. The total data volume is displayed in time.

 Here, middleware for network control and management is required for the devices on the network to operate in cooperation as shown in Fig. 1. Here, middleware is located between lower-level software such as an OS, network control program, or data base system, and higher-level applications, and provides various services to applications. It is software that performs Furthermore, even if devices from different manufacturers are connected to the network, a common specification that the middle drivers must conform to is essential for the network to operate properly and for the devices to interoperate. is there. Here, a network system in which HAVi (Home Audio / Video Interoperability Architecture) (trademark) is applied as middleware for network control and management will be described.

FIG. 4 shows an example of a software stack stored on the hard disk 30 provided in the IRD 2 shown in FIG. In Figure 4, Modules shown above are at the higher level than modules shown below. 1 3 94 The part excluding Dryno, '(driver), Application and Attributes List is a software module corresponding to HAV i.

 The 1394 driver is a module that describes the part that depends on the IEEE1394 serial bus 1, and is software that provides higher-level software with a shared procedure for device access. The CMM (Communication Media Manager) 1394 serves as an interface between the IEEE 1394 serial bus 1 and each of the AV i software modules and applications. The CMM 1394 provides a transmission mechanism for transmitting and receiving signals between devices connected to the IEEE 1394 serial bus 1. To other software modules.

 A messaging system acts as an API (Application Programming Interface) for communication between software modules of each device on a network, and transmits messages between software modules. Play a role. For this reason, in a network employing HAVi, a message sending side and a message receiving side can transmit a message without knowing each other's location on the network.

The DCM manager installs a DCM and an AVD IS CFCM described later for each device on the network. In a network employing HAVi, the DCM manager When a new device is connected to the network, the DCM and AVDISCFCM corresponding to the newly connected device are installed.When the device is disconnected from the network, the DCM and AVDISCFCM corresponding to the disconnected device are installed. Uninstall it.

 The event manager generates events when the state of the network changes, for example, when a new device is connected to or disconnected from the network, and other software is generated. It plays a role in transmitting to the to-air module. As a result, it is possible to realize the brag and play in a network employing HAVi.

 The registry holds or updates information about devices, such as what devices are connected to the network and what functions the devices have. Yes, allowing interaction between different devices. The application program gets the necessary information from this registry. In addition, each device on the network can confirm the location of the basic software module of another device on the network by referring to the registry.

The Stream Manager monitors and manages the stream data such as video and audio, that is, the continuous data flow on the network, and enables the real-time transmission of stream data. In addition, the stream manager manages connections inside and between devices, secures and releases network resources, and provides connection information for the entire network. In addition, the stream manager supports reconnection after a network bus reset. 00/07159

11 You can also drop.

 Resource Manager manages scheduled events, such as handling device usage rights conflict issues, processing reserved for connected devices, and does not remove devices after registration Monitor the network, such as

 The Application detects the identification data of the data stored on a recording medium such as a CD mounted on a device such as a CD player connected to the network, and identifies the same identification data in the attribute list. This is for executing a process of determining whether or not there is data. The details of the attribute list will be described later.

 The DCM controls the device and is installed from the CD player 3. The application program does not directly control each device connected to the network, but controls each device via the corresponding DCM. AVD IS CFCM is installed from the CD player 3 and indicates the control contents and functions executed by the application program for each device. Send C command. Since DCM and AVDISCFCM function as APIs, the application program itself does not need to consider differences between individual devices. Therefore, in a network employing HAVi, a device on the network can recognize the function of another device, and can operate another device from a remote place.

The Attributes List is configured, for example, as shown below. Attributes List {

 UniquelD []:

 Attributes Data []

 }

 Attributes Data {

 Title ：

 Title Description:

 Artist:

 Image:

 Track []

 TrackDescription []

 } In this attribute list, UniquelD []: stores the ID for media recognition, and AttributesData [] stores the attribute data (related information) related to the media. In the AttributesData, Title: is the title, Title Description is the title description, Artist is the author, Image is the image file, and Track [] is the track title. For example, a song name and time are stored, and a track description is stored in Track Description [].

 The software module as described above is owned by each device connected to the network according to the class of the device specified in HAVi. In HAVi, the following four types of equipment classes are specified.

FAV (Full AV Device) has a function to manage the network. It is assumed that the device will be compatible with all of the above-mentioned HAV i software modules. Note that the FAV may not have the DCM and the AVD ISCF CM in some cases. For example, the FAV can be installed from the BAV described later. The FAV can execute an application using JAVA (trademark) adopted as HAVi byte code. Thus, the FAV can own the DCM and FCM of another device, and by controlling the DCM and FCM of the other device, can bring the other device under control.

 The IAV (Intermediate AV Device) is assumed to be a device that has the function of managing the network in the same way as the FAV, but unlike the FAV, it uses JAVA, which is adopted as the HAVi byte code. In this environment, the application cannot be executed, so the DCM and FCM of other devices are installed in advance.

 The BAV (Base AV Device) is a controlled device that can be directly connected to the HAVi network, and has its own DCM and FCM. The LAV (Legacy AV Device) has only the function as a device that can be connected to the IEEE 1394 serial bus 1.However, in order to support AV / C commands, in addition to operating alone, controlled devices It is possible to operate as.

In the present invention, the IRD 2 will be described as a device corresponding to FAV (IEEE 1394 interface 21 as CMM 1394), and the CD player 3 as a device corresponding to BAV. As shown in Fig. 5, the FAV IRD 2 can control the CD player 3 by installing the DCM and AVD I SCFCM of the CD player 3 BAV. Wear.

 Next, the related information input processing executed by the IRD 2 will be described. First, a case where the control device IRD 2 selects the CD player 3 as the controlled device and CD as the read-only recording medium will be described with reference to FIG. Here, IRD 2 is activated, and for example, a device selection screen Iftl is displayed on the LCD 29 which is a display section, and a CD is selected.

 Then, although detailed description is omitted, each software module of the software software described with reference to FIG. 4 is read from the hard disk 30 to the CPU 23 and executed.

 First, in the related information input processing, as shown in FIG. 6, in step S1, the application requests the AVDI CFCM to notify the user of a CD inserted when the CD is inserted. In step S2, the AVDI SCFCM requests the event manager to notify an event indicating that a CD has been inserted when the CD is inserted. Then, the AVDISCFCM acquires the status of the CD player 3 through a messaging system (CMM1394).

 Here, since the CD is selected as the device, a display screen for operating the CD player 3 is displayed on the LCD 29 as a user interface (UI) in step S3. As this display mode, the one shown in FIG. 7 is used.

In step S4, it is determined whether a CD has been inserted into the CD player 3. If the CD is not inserted into the CD player 3, the process ends here. That the CD has been inserted into the CD player 3 If detected, in step S5, the application sends an AVDISC: get—TOC HAVi message to the AV DISCF CM to request acquisition of the T0C data recorded on the CD. In step S6, the AVD IS CF CM requests the CD player 3 to send the T • C data recorded on the CD. Upon receiving the request from the AVD ISCF CM, the CPU 53 provided in the CD player 3 controls the reproduction processing unit 56 to reproduce the TOC data recorded on the CD in step S7. The CPU 53 reads the detected T0C data and transmits it to the AVD ISCF CM. In the present invention, the request for the T0C data is requested, but the request for obtaining the CD-text data including the title of the album may be made.

 In step S8, the AVDISCFCM transmits the received TOC data to the application. In step S9, the application compares the T〇C data received from the AVDISCFCM with the T0C data in the attribute data already stored in the attributes list and finds a match. It is determined whether or not there is data, that is, whether or not there is TOC data having the same total number of tracks and the data amount of each track, for example, the same reproduction time. Here, TOC data is used to identify the CD, and if there is other identification information, it may be used.

If it is determined in step S9 that there is a match with the T0C data in the attribute data stored in the attribute list, the process proceeds to step S10, and the application proceeds to step S10. The attribute data corresponding to the matched T 0 C data is read from among them, the contents thereof are displayed on the LCD 29, and the series of processing ends. Where L CD 2 9 displays a GUI as shown in FIG.

 At this time, the application sends, for example, an HAV i message defined as follows to the AVD ISCF CM, and the application stores the HAV i message in the attribute list corresponding to the T0C data in the attribute list. Request title, title description, author, track title, track description, and image file. Therefore, by transmitting these messages, the GUI shown in FIG. 7 is displayed on LCD 29.

 The display field 61 in FIG. 7 displays the currently selected track number and the data length of the track, for example, the playing time. Here, immediately after the attribute data is read, the first track number is selected, and in the example shown in Fig. 7, the time of the first track is now 12 minutes and 5 seconds. Is displayed. During playback, the time displayed in the display column 61 is the halfway time during playback. Further, the title is displayed in the display column 68, the author is displayed in the display column 69, and the track evening title is displayed in the display column 70.

Then, when the pull-down key 71 in the GUI shown in FIG. 7 is pressed by the user, a list box 81 is displayed as shown in FIG. The user can move the cursor 82 up and down to Select a tool.

 When the icons 62 to 66 are set by the user, the application will play the AVD ISCF CM in Play, Pause, Stop, Stop, Reverse, Fast Forward. (Forward) Set to one of the operation modes in the state. When the icon 67 is set by the user, the application can eject the CD. That is, when the icons 62 to 66 are set by the user, the application outputs, for example, an HAVI message defined as follows to the AVDISCFCM, respectively.

 A VD I S C: Play

 A VD I S C: Pause

 A VD I S C: Stop

 A VD I S C: Reverse

 A VD I S C: Forward

 Upon receiving such a message from the application, the AVD IS CFCM sends the message to the CD player 3 via the internal bus 22, the IEEE 1394 interface 21 and the IEEE 1394 serial bus 1, respectively. Output AV / C commands of Play, Pause, Stop, Reverse, Forward, and Eject). Upon receiving these AV / C commands, the CD player 3 performs predetermined processing, for example, play, pause, stop, rewind, fast forward, or eject.

Further, when the icon 72 is settled by the user, the application switches the GUI to an edit screen described later, and ends when the icon 73 is settled. Returning to FIG. 6, when it is determined in step S9 that none of the T0C data in the attribute data stored in the attribute list matches the received T0C data. That is, if it is determined that the attribute list does not yet store the relevant information of the CD, the process proceeds to step S11, and the application displays the GUI display fields 68 to 7 shown in FIG. Leave 0 blank to display the attribute data table. Next, an operation procedure in which the user inputs related information such as a title after the processing of step S10 or step S11 shown in FIG. 6 will be described with reference to FIG.

 In the state where the operation procedure for inputting the related information by the user is selected, the GUI shown in FIG. 7 is displayed on the LCD 29 in the step 21 shown in FIG. 9 through the procedure shown in FIG. 6 described above. State. Next, in step S22, the user determines whether or not to input relevant information such as a title, and if it is determined to input relevant information such as a title, the user displays an editing screen. For this purpose, the icon 72 shown in FIG. 7, that is, the edit icon 72 is set.

 When the edit icon 72 is operated, the process proceeds to step 23. In step 23, the application displays a GUI, for example, as shown in FIG. GUI shown in FIG. 10 is an edit screen on which relevant information such as a title is input.

 When the edit icon 72 is not operated, the display state of the GUI shown in FIG. 7 is continued.

When displayed on the GUI shown in FIG. 10 in step 23, in step 24, the user inputs relevant information such as a title. In this step 24, the user Using the keyboard displayed in 8, enter a title in the input box 91, enter a title description in the input box 92, enter the author in the input box 93, and enter a track title in the input box 94. The track description can be entered in the input field 95. In the input field 96, an image file, which is image data, is attached. As a method of acquiring image data overnight, for example, there is a method of downloading image data distributed by a record company or the like from the Web. Here, the input column 91 is linked to the display column 68 (see FIGS. 7 and 8), the input column 93 is linked to the display column 69, and the input column 94 is linked to the display column 70. , 94, the input data is displayed in display fields 68 to 70, for example.

 In step S24 shown in FIG. 9, the user inputs a title or the like based on the GUI shown in FIG. 10, and in step 25, presses the confirmation icon 97 shown in FIG. When the input is confirmed, the application sends an HAV i message, defined as follows, to the AVD IS CF CM, and the title, title description, author, and track title are included in the attribute list. Requests the setting of the title, track description and attribute data of the image file.

 A VD I S C: set—Title

 A VD I S C: set—Title—Description

 A VD I S C: set one Artist

 A VD I S C: set—Track—Description

 A VD I S C: set—Image

In step S26, the application enters the attribute list The contents of the attribute data (related information) input in step S24 are stored, and the process ends.

 In step 25, if the input is not confirmed and the cancel icon 98 shown in FIG. 10 is operated, the GUI shown in FIG. 10 is displayed on the editing screen which enables the input of related information such as evening titles. And In this case, the state in which the GUI of step 21 is displayed may be returned.

 If it is determined in step S22 that no title or the like is input, the process returns to step 21 to continue the GUI display state shown in FIG. 7 as described above.

 In the related information input processing shown in FIG. 6, the processing is started from a state where the controlled device is not selected in the IRD 2, but the CD player 3 may be selected in advance as the controlled device. In this case, the input processing of the related information is performed through a procedure as shown in FIG.

 That is, if the CD player 3 is previously selected as the controlled device, as shown in FIG. 11, when the CD is loaded into the CD player 3 in step 31, the CD is inserted in step 32. Notify the event manager of the event. Upon receiving the response from the CD player 3, the event manager notifies the application that the CD has been inserted in step S33. After that, the same procedure as the procedure from step 5 onward shown in FIG. 6 is performed, so that detailed description is omitted.

 Next, with reference to the flowchart of FIG. 12, a procedure of a reproduction process of music data recorded on a predetermined recording track of the CD will be described.

To play back the song data recorded on the CD, Has been inserted, the processing in steps S1 to S10 shown in FIG. 6 has already been executed, and the GUI shown in FIG.

 In step S41, when the user operates the pull-down key 71, the application causes the LCD 29 to display the list box 81 shown in FIG. The user moves the cursor 82 up and down to select a recording track on which music data to be reproduced is recorded. Further, the user operates the icon 62 for selecting the reproduction operation mode, and instructs the CD player 3 to reproduce the recording track.

 Based on the user's instruction, in step S42, the application sends an AVDISC: Play HAVi message to AVDISCCFCM to notify the playback of the selected track. In step S43, the AVD IS CFCM receives the message from the application and sends the message to the CD player 3 via the internal bus 22, the IEEE 1394 interface 21 and the IEEE 1394 serial bus 1, and the P 1 ay. Output AV / C command to notify the playback of the selected recording track.

In step S44, when the CPU 53 receives the notification from the AV DISCF CM, the CD player 3 controls the reproduction processing unit 56 to reproduce the selected recording track. In step S55, the abridgement determines whether or not a stop has been instructed by the user, that is, whether or not the icon 64 for stopping playback shown in FIG. 7 has been operated, or It is determined whether or not the reproduction has been completed. If both are determined to be No, the process returns to step S44 to repeat the above-described processing. In step S55, if any of the determinations are Yes, the process proceeds to step S46, where the application determines whether the user has instructed the generation of another recording track, and determines whether another recording track has been generated. If it is determined that the reproduction has been instructed, the process returns to step S42, and the above-described subsequent processes are repeated. If it is determined that reproduction of another recording track has not been instructed, the process is terminated.

 As described above, the user information such as the title and description of the CD inserted into the CD player 3 on the controlled side (BAV) is stored in the attribute list of the IRD 2 on the controlling side (FAV). By storing as, even a read-only CD that cannot be recorded can be managed based on the related information added by the user. That is, by using the present invention, the user can listen to the songs on the CD while looking at the screen of his or her preference, and further, the user can obtain the impression that he or she has received before for each song on the CD album. By reading, you can select and listen to only the songs you like.

 In the above description, the case of playing a CD has been described as an example. However, the present invention can be applied to, for example, a read-only DVD (digital versatile disc).

Furthermore, for example, a magneto-optical disc player using a recording / reproducing magneto-optical disc as a recording medium is connected to the IEEE 1394 serial bus 1, and the data of the CD inserted in the CD player 3 is dubbed to the magneto-optical disc. In this case, the magneto-optical disc player can dub the stream data streamed from the CD player 3 and record the attribute data stream (related information) streamed from the IRD 2 as well. The user inputs a title or the like to the magneto-optical disk again. There is no need to
