Description

  The present invention relates to a device selection control technique using wireless communication.

  As a conventional technique, specific processing performed in a processing device connected to a network, for example, processing such as video and audio output, program execution, text editing work, and the like (hereinafter, these processing are referred to as “services”) Has been proposed in which a processing apparatus connected to another network is taken over continuously.

  As a method for moving the above-described service, there is a technique using an IC card or password authentication. When using an IC card, information on the source processing device is stored in the IC card, and the information on the source processing device is read into the destination processing device by mounting the IC card in the destination processing device. Service migration processing is performed. Also, in the case of password authentication, information on the migration source processing device is set in advance in the migration destination processing device, and service migration processing is performed by inputting a password to the migration destination processing device using a keyboard. However, an operation using an IC card or inputting a password is necessary, and there is a problem in convenience.

  In addition, a technique for designating a processing apparatus at a movement source or a movement destination by using a GUI (Graphical User Interface) of the processing apparatus has been used. However, with this technique, as the number of devices connected to the network increases, the number of items to be selected increases, and it takes time and effort to search for a processing device desired by the user.

  As a method for solving these problems, a technique for designating each processing device using wireless communication having directivity such as infrared rays is disclosed (for example, see Patent Document 1).

  In this technique, a user can easily specify a desired processing device by using a pointing device such as a remote controller and transmitting a predetermined signal to the processing device to be operated by the user by directing the remote control.

  A general infrared remote controller transmits and receives 32-bit data using infrared light modulated at 38 to 40 kHz. Each bit of data can represent 0 and 1 by changing the pulse interval.

For example, as shown in FIG. 19, in an environment where a television (movement source processing apparatus) 3 and a projector (movement destination processing apparatus) 4 are connected to a network such as a LAN, the movement source treatment apparatus 3 moves to the movement destination processing apparatus 4. When moving the video display processing, the user operates the directional infrared remote controller (instruction device) 2 toward the processing device that desires movement or duplication. Such an intuitive operation enables selection of the movement source device and the movement destination device.

  However, in Patent Document 1, it is assumed that only a specific processing device can be selected by wireless communication with directivity. However, in wireless communication with directivity, the range of directivity depends on the communication means used. The area varies, and when a range of directivity is wide and a plurality of processing devices exist within the wireless range, a specific processing device cannot be designated. In addition, when the wireless range is narrowed so that a plurality of processing devices do not enter the wireless range, the pointing device must be accurately directed toward the processing device, and the direction in which the pointing device is pointed is subtly shifted. In some cases, there is a problem that a desired processing apparatus cannot be selected correctly.

[Select processing equipment]
Below, the flow which selects the processing apparatuses 3 and 4 in the control system 1 which concerns on this invention is demonstrated with reference to above-mentioned FIGS. 2-4 and the following drawings.
FIG. 5 is an example of a system configuration in the case where there are a plurality of processing devices that are migration source candidates.
FIG. 6 is a sequence diagram illustrating the procedure of device selection processing when there are a plurality of processing devices that are candidates for the movement source.

  In FIG. 5, a plurality of processing apparatuses such as the processing apparatus A22 and the processing apparatus B23 are installed adjacent to each other. In this embodiment, a processing device desired by the user is selected as a movement source device from a plurality of processing devices, and the service processed by the movement source processing device is transferred to the movement destination processing device. Here, a television is illustrated as the processing device A22 and the processing device B23, and a projector is illustrated as the destination processing device 24. However, the processing device A22 and the processing device B23 are not limited to this as long as the device can perform data processing or reproduction. The service for moving is not limited to those described in the embodiments. The processing device A22, the processing device B23, the movement destination processing device 24, and the control device 5 are connected by a network such as a LAN. The network is not limited to wired communication, and wireless communication may be used. Assume that both the processing device A22 and the processing device B23 are performing different video output processing.

First, the user performs an operation for transmitting a movement source selection signal to the target processing device toward the instruction device 2 (S101).
The control unit 7 of the instruction device 2 acquires information from the state holding unit 8 and the random number generation unit 9 in response to a user operation via the input unit 6, generates a movement source selection signal, and transmits directional communication. The movement source selection signal is transmitted to the processing devices A22 and B23 through the unit 10. An example of an instruction signal such as a movement source selection signal is shown in FIG.

  As shown in FIG. 7A, the instruction signal basically includes a remote ID (remote controller ID) 25, a session ID (session ID) 26, a signal ID (signal ID) 27, and the like.

  The Remote ID 25 is an identifier unique to the pointing device, and is unchanged unless the pointing device changes.

  The Session ID 26 is an ID for identifying one process (service migration or duplication) that is performed by the instruction device 2, and can be moved or duplicated by operations of selection of the source (destination) device, service selection, and service execution. The same ID is used until a series of operations are completed.

  In the present embodiment, when the instruction device 2 transmits a signal, the signal always includes the session ID 26 in the signal. Further, when another operation is performed after completing a series of operations, it is necessary to generate a new Session ID 26 and change the Session ID 26 used so far to the newly generated Session ID 26. The session ID 26 may be changed by a user operating a button or a touch panel of the instruction device 2 or may be changed by determining that the instruction device has different processing due to automatic control. The Session ID may be generated from a random number, or may be generated from a counter or time information.

The Signal ID 27 is an ID indicating the type of the instruction signal, and there are types as shown in FIG.
The types of instruction signals shown in FIG. 7B will be described.

  The movement source (movement destination) selection signal is a signal for performing a selection operation of a processing apparatus that is a movement source apparatus or a movement destination apparatus.

  The service selection signal is a signal for selecting a desired service from among the services that can be used by the movement source processing apparatus, the movement destination processing apparatus, or the combination of the movement source processing apparatus and the movement destination processing apparatus.

  The movement (duplication) execution signal is a signal for instructing the start of the movement (duplication) of the service from the designated movement source processing apparatus to the movement destination processing apparatus.

  The signal / message control unit 12 of the processing device A22 or the processing device B23 that has received the movement source selection signal from the directional communication reception unit 11 determines whether or not each of them can currently operate as the movement source processing device (S102).

  This determination process will be described in detail in conjunction with the determination process when a destination selection signal is received in the item [Signal Determination Process in Processing Device].

  Here, it is assumed that both the processing device A22 and the processing device B23 are operable. Next, the signal / message control unit 12 of the processing device A22 and the processing device B23 transmits a source candidate registration message from the network communication unit 13 to the control device 5 (S103, S104).

An example of a message such as a migration source candidate registration message is shown in FIG.
The message is data exchanged between the processing device A22 or the processing device B23 and the control device 5 through a network. The message basically takes the form of FIG.

  The Remote ID 25 and the Session ID 26 included in the message use the instruction signal used for the series of processes up to that point and the Remote ID 25 and the Session ID 26 included in the message as they are.

  Message ID (message ID) 28 indicates the type of message, and indicates the type of message as shown in FIG. The meaning of the message type will be clarified individually in the explanation of the procedure.

  The parts of Remote ID 25, Session ID 26, and Message ID 28 are the header part of the message, which is a common part included in all messages. Necessary information is added to each message as an optional part after Message ID28.

  The migration source candidate registration message is a message transmitted to the control device 5 by a processing device that is operable as a migration source device by the processing device that has received the migration source selection signal. As shown in FIG. 8D, this message includes a Service ID (service ID) 29 and a Host ID (host ID) 30 as optional parts.

  The Service ID 29 indicates the type of service, and indicates the type of service as shown in FIG. Examples of services include audio, video, files, and programs.

  The Host ID 30 is an identifier unique to the processing device necessary for network connection.

  The Service ID 29 included in the migration source candidate registration message represents a service that can be migrated or copied by the processing device that transmits the message.

  The processing apparatus that has transmitted the source candidate registration message waits for the arrival of the source candidate notification message from the control device 5 for a certain period of time.

  In this embodiment, it is assumed that the migration source candidate registration message of the processing device A22 has arrived first at the control device 5 depending on the load status, processing capability, and network status of the processing devices A22 and B23 (S103). .

  As a processing flow of the control device 5 after this, the source candidate registration message is received from the processing device A22 or the processing device B23 via the network communication unit 18, but the message control unit 20 is configured to use a header part (Remotecon ID25, Session). When a plurality of migration source candidate registration messages having the same ID 26, Message ID 28) are received, one of them is selected, and processing for transmitting the migration source candidate notification message to the processing device that is the migration source candidate is performed. become.

  Hereinafter, device candidate determination (S105) of the control device 5 that has received the source candidate registration message will be described with reference to the device candidate selection flowchart of FIG.

  The message control unit 20 of the control device 5 that has received the migration source candidate registration message first selects the remote candidates 25 and Session IDs 26 included in the migration source candidate registration message in the storage unit 19 as shown in FIG. It is determined with reference to whether there is a match with Remote ID 31 and Session ID 32 registered in the table (S201).

  In the selection candidate table, information relating to a migration source (destination) processing apparatus and service that has already been selected is registered. The selection candidate table includes a remote ID 31, a session ID 32, a host ID 33 of the migration source processing device, a service ID 34 of the migration source processing device, a host ID 35 of the migration destination processing device, a service ID 36 of the migration destination processing device, and a transfer or replication target. There is an item of candidate Service ID 37 indicating the service to be.

If there is no match as a result of the determination, the process proceeds to S203.
If there is a match, the Service ID 29 included in the migration source candidate registration message is the service ID 36 of the migration destination processing apparatus (in the case of the migration destination candidate registration message) among the items whose Remote ID 31 and Session ID 32 of the selection candidate table match. Determines whether or not a service matching Service ID 34) of the migration source processing apparatus or Service ID 37 that is a candidate for migration is included (S202).

  If the result of determination is that no match is found, the determination ends. If a matching item is included, the process proceeds to S203.

  Accordingly, when a source (move destination) processing device is selected first and a destination (move source) processing device is selected later, a processing device that cannot provide a desired service can be automatically excluded from the selection. In addition, since the number of operations for transmitting the movement destination (movement source) selection signal by the instruction device 2 can be reduced, the convenience for the user is increased.

  Next, the message control unit 20 of the control device 5 registers the Remotecon ID 25 and the Session ID 26 included in the movement source candidate registration message in the candidate device selection table as shown in FIG. It is determined by referring to whether there is a match with the remote ID 38 and the session ID 39 (S203).

  As shown in FIG. 11, the candidate device selection table includes items such as Remote ID 38, Session ID 39, Message ID 40, Host ID 41, Service ID 42, and Counter (counter) 43.

  If the result of the determination is a match, the process proceeds to S204. If there is no match, the process proceeds to S208.

  If there is a match in S203, the message control unit 20 determines whether or not the same ID as the Host ID 30 of the migration source candidate registration message is registered in the corresponding record of the candidate device selection table (S204). ).

  If registered, the process proceeds to S205, and if not registered, the process of S208 is performed.

  The message control unit 20 saves the information included in the migration source candidate registration message in the temporary storage unit 21 when the determination in S204 matches (S205).

  Next, for example, the message control unit 20 first receives a message including information on the Remotecon ID 25, the Session ID 26, and the Message ID 28 (in this case, “move source candidate”) after the device candidate determination process is reset. The time is counted by a counter or the like from the time of reception, and after a predetermined time elapses (S206), a record in the candidate device selection table that matches the ID of the source candidate registration message stored in the temporary storage unit 21 is displayed. Extraction is performed, and the counter value 43 of the record is compared (S207).

  Among them, the processing of S208 is performed for the message with the smallest counter value 43 (represented as “minimum”, but any method is acceptable as long as it represents the record that has passed the most time since the previous selection). .

  The message control unit 20 determines whether a source candidate notification message has already been transmitted to the processing device for the same Remotecon ID 25 and Session ID 26 and a certain time has not elapsed (S208). Here, the determination as to whether or not the predetermined time has elapsed is made to distinguish the number of times the instruction signal from the instruction device 2 has been transmitted. When the predetermined time has elapsed, the message control of the control device 5 is performed. The unit 20 determines that the process is to receive a new signal from the instruction device 2, clears the previous message transmission record in the temporary storage unit 21, and transmits the source candidate notification message again.

  If the determination in S208 is true, the processing of the migration source candidate registration message is terminated. The fixed time can be arbitrarily set, and the counter may be used in the same manner as described above.

  In S208, the message control unit 20 does not transmit the migration source candidate notification message to the processing device within a predetermined time, and the ID of the migration source candidate registration message (Remote ID 25, Session ID 26, part of Service ID 29, Host ID 30). When the record that matches is in the candidate device selection table and the source candidate notification message is transmitted, the counter value of the record in the candidate device selection table is increased. The counter value is larger than the counter value 43 of the record having the maximum counter value in the case where there are a plurality of records that match any of the services in Remote ID 38, Session ID 39, Message ID 40, and Service ID 42. Value. If there is no matching record and the source candidate notification message is transmitted, a new record is registered.

Further, the information of the movement source candidate registration message is also registered in the selection candidate table shown in FIG.
In the selection candidate table, the same Remote ID 31 and Session ID 32 as those of the migration source candidate registration message are already registered, and if the migration source device is registered, the migration source item of the record is the registration of the migration destination device. For example, when the item of the movement destination of the record is registered, the items of Host ID 33 (or 35) and Service ID 34 (or 36) are overwritten. Then, the source candidate notification message is transmitted to the processing device indicated by the Host ID 30 included in the message (S209).

  The migration source candidate notification message is a message to be transmitted to the migration source processing device selected from the migration source candidate registration messages received by the control device 5, and was added to the migration source candidate registration message in the option section. Service ID 29 is attached as it is.

  Here, it is assumed that the processing device A22 is selected as a movement source candidate. The message control unit 20 of the control device 5 transmits a source candidate notification message to the processing device A22 selected as the source candidate from the network communication unit 18 (S106).

  The signal / message control unit 12 of the processing device A22 that has received the movement source candidate notification message from the network communication unit 13 instructs the status display unit 15 to display that it is a movement source candidate, and the processing device B23. Since the message / message control unit 12 has not received the message within a predetermined time after transmitting the movement source candidate registration message to the control device 5, the signal / message control unit 12 instructs the status display unit 15 to display that it is not the movement source candidate ( S107).

  At this point, the status display unit 15 presents that the processing device A22 is the processing device that is the movement source, and is recognized by the user. When the processing device different from the processing device presented by the user is selected, the pointing device 2 is operated again toward the processing device B23, and the control unit 7 of the pointing device 2 generates a movement source selection signal. (S108).

The signal / message control unit 12 of the processing device A22 and the processing device B23 that have received the movement source selection signal performs the processing from S109 to S111 in the same manner as the processing described above.
The message control unit 20 of the control device 5 selects the processing device that has transmitted the movement candidate registration message and has not been selected as a movement source candidate so far or has the oldest selected time. Then, the process of the apparatus candidate selection flowchart of FIG. 9 is performed. This time, since the processing device B23 has never been selected as a movement source candidate, the message control unit 20 of the control device 5 selects the processing device B23 (S112), and the network communication unit 18 notifies the movement source candidate. A message is transmitted (S113).
Next, the processing device A22 and the processing device B23 display the result of whether or not the movement source candidate notification message has been received by the respective status display units 15 (S114).

  At this stage, the fact that the processing device B23 has been selected as a new source device candidate is presented by the status display unit 15 of the processing device B23 and recognized by the user.

  Further, when the processing device different from the processing device presented by the user is selected, the pointing device 2 is operated again toward the processing device A22, and the pointing device 2 generates and transmits a source selection signal. (S115). As before, the signal / message control unit 12 of the processing device A22 and the processing device B23 transmits a source candidate registration message (S117, S118), and the message control unit 20 of the control device 5 transmits the message. The processing device A22 having the oldest selected time is selected from the devices (S119), and the source candidate notification message is transmitted from the network communication unit 18 (S120).

  Whether or not each processing device is a candidate is displayed on the status display unit 15, and the user recognizes that the processing device A22 is selected as a selection candidate (S121).

  The instruction device 2 transmits a movement destination selection signal or a service selection signal to the processing device A22 or the processing device B23 (S122), and the message control unit 20 of the control device 5 sends a movement destination candidate registration message or a service selection request from the processing device. When a message having a different type of Message ID 28, such as a message received so far, is received, it recognizes that the candidate selection process of the source processing device has been completed, and sets the flag of the selection candidate table in the storage unit 19 The confirmation is made and the movement source processing apparatus is confirmed (S123).

  In this embodiment, the case where there are two candidate processing devices has been described, but it is clear that the user can select a processing device desired by the same procedure even when the number of processing devices increases. It is.

  After this, the selection processing of the destination processing device is performed, but the selection processing of the source processing device is the same as the processing flow, and the instruction signal type, message type, and display contents on the processing device are moved from the source. The processing is advanced according to the movement source selection sequence in FIG. 6 and the apparatus candidate selection flowchart in FIG.

  For example, in FIG. 6, the movement source selection signal from the instruction device 2 to the processing device is the movement destination selection signal, the movement source candidate registration message is the movement destination candidate registration message, and the movement source candidate notification message is the movement destination candidate notification message. It will be changed. That is, according to FIG. 7, Signal ID 27 of the instruction signal is changed to move destination selection, and according to FIG. 8, Message ID 28 of the header part of the message is changed to move destination candidate registration or move destination candidate notification. The processing in the control device 5 is the same as the movement source selection.

  To confirm the destination processing device, the instruction device 2 transmits a service selection signal or the like to the processing device, and the message control unit 20 of the control device 5 receives the message and message that have been received so far, such as a service selection request message from the processing device. This is performed by recognizing that the candidate selection process of the processing apparatus at the movement destination has been completed by receiving a message with a different type of ID 28 and confirming the flag of the selection candidate table in the storage unit 19.

  By performing the processing as described above, even in an environment in which a plurality of processing devices are arranged within the wireless range, the user selects one device that the user wishes to designate as the movement source processing device and the movement destination processing device. The service can be moved or copied.

  In addition, since an unselected processing device or a processing device that has passed the most time since the previous selection is selected as the movement source processing device or the movement destination processing device, efficient processing device selection is possible. Become.

[Signal determination processing in processing device]
Here, the processing in the processing device that has received the movement source selection signal or the movement destination selection signal from the instruction device 2 will be described in detail with reference to the selection processing flowchart in the processing device of FIG.

  First, the signal / message control unit 12 of the processing device determines whether the signal received from the instruction device 2 is a movement source selection signal or a movement destination selection signal (S301). This determination can be made by recognizing the type of Signal ID 27 of the received signal.

  Next, the signal / message control unit 12 of the processing device determines whether the processing of the received signal can be continued by comparing the current state of the processing device with the received signal.

  That is, when the received signal is a movement source selection signal, the determination is made based on whether one or more services among the services that can be moved to another processing apparatus are being processed or are in a process waiting state. As a condition for accepting the movement source selection signal, for example, the processing device is processing or waiting for services such as video and audio reproduction and program execution, and the movement or copying of these services is not prohibited. (S302).

  If the received signal is a destination selection signal, it is checked whether there is a service that is not currently processed, and it is determined whether or not the destination device can be operated (S312).

  The signal / message control unit 12 of the processing device determined to be unacceptable as the movement source device or the movement destination device in the determination of S302 or S312 has received the movement source (movement destination) selection signal in the status display unit 15, but has moved. The fact that it is not accepted as the original (destination) apparatus is displayed (S320).

  Next, the signal / message control unit 12 determines whether it is a candidate for another movement source (movement destination) selection signal (S303, S313). As a result of the determination, if it is a candidate for another movement source (movement destination) selection signal, it is displayed that the signal has been received by the status display unit 15 of the processing apparatus but cannot be accepted as a movement source (movement destination) candidate. (S320).

  If it is not a candidate for another movement source (movement destination) selection signal, the signal / message control unit 12 transmits a movement source (movement destination) candidate registration message from the network communication unit 13 to the control device 5 (S304, S314). ).

  The processing apparatus that has transmitted the movement source (movement destination) candidate registration message waits for arrival of a movement source (movement destination) candidate notification message from the control apparatus 5 for a certain period of time by using a counter or the like. The signal / message control unit 12 determines whether or not a movement source (movement destination) candidate notification message has been received from the control device 5 within the time (S305, S315).

  Alternatively, the control device 5 transmits a message notifying that it has not been selected as a candidate to a processing device that has not been selected as a candidate, and the determination of this processing device is a movement source (movement destination) candidate notification message or It may be determined which of the messages notifying that it has not been selected has been received.

  The signal / message control unit 12 of the processing apparatus that has received the movement source (movement destination) candidate notification message stores information indicating that it has become a movement source (movement destination) candidate of the movement source (movement destination) selection signal in the storage unit. Save (S 306, S 316), and output to the status display unit 15 that it has become a movement source (movement destination) candidate. This output may be displayed using an icon, or may be displayed by characters or LED lighting (S320).

  The signal / message control unit 12 of the processing apparatus that has transmitted the movement source (movement destination) candidate registration message and has not received the movement source (movement destination) candidate notification message receives the movement source (movement destination) selection signal. If it is determined that it is not a movement source (movement destination) candidate and has previously been a movement source (movement destination) candidate of the movement source (movement destination) selection signal, the information is deleted from the storage unit 14. Then, it displays on the status display unit 15 that it has received the movement source (movement destination) selection signal but is not a movement source (movement destination) candidate (S320).

[Select service]
After either or both of the movement source processing apparatus and the movement destination processing apparatus are confirmed, the service selection operation is performed.

  A procedure for selecting a service will be described with reference to a service selection sequence in FIG.

In the present embodiment, the description will be given on the assumption that the user selects one of the video service, the audio service, and all (video and audio) services as the service to be selected.
First, the operation of the pointing device 2 will be described. An instruction signal corresponding to a user operation is generated by the control unit 7 and transmitted from the directional communication transmission unit 10.

  First, the control unit 7 generates a service selection signal from the Remote ID 25, Session ID 26, and Signal ID 27 by the user operating the input unit 6 of the pointing device, and the directional communication transmission unit 10 sends it to the processing device. Send. Here, the type of Signal ID 27 is service selection, and Remote ID 25 and Session ID 26 are the same as the movement source (movement destination) selection signal (S401).

  In this procedure, a processing apparatus to which a signal is transmitted is normally a source or destination processing apparatus, but may be any processing apparatus connected to a network.

  The signal / message control unit 12 of the processing device that has received the service selection signal from the directional communication receiving unit 11 extracts a movable service from the storage unit 14 using the Remote ID 25 and the Session ID 26 included in the received service selection signal. The service selection request message is generated with the service ID 29 as a service ID 29 and transmitted to the control device 5 (S402).

  The service selection request message is a message that the processing device transmits to notify the control device 5 that a service selection signal has been received.

  The message control unit 20 of the control device 5 that has received the service selection request message from the network communication unit 18 selects a service that is a candidate to be presented to the user from the Service ID 29 included in the message (S403), and performs processing from the network communication unit 18 A service candidate notification message is transmitted to the apparatus (S404). The service candidate notification message includes the service ID 29 of the selected service.

  The processing device to which the control device 5 transmits the service candidate notification message can be set as any or all of the processing device, the movement source processing device, and the movement destination processing device that have transmitted the service selection request message.

  Next, processing when the control device 5 receives a service selection request message will be described with reference to a service determination flowchart of FIG.

  The message processing unit 20 of the control device 5 that has received the service selection request message from the network communication unit 18 first stores candidates (entries) having the Remote ID 25, the Session ID 26, and the Host ID 30 included in the message in the storage unit 19. It is determined whether it is registered in the selection candidate table shown in FIG. 10 (S501). When there is no entry having the same Remotecon ID 31, Session ID32, and Host ID33 (or 35) included in the message, the message control unit 20 of the control device 5 selects the processing device as the processing device of the message transmission source. A candidate unselected message is sent to notify that there is no message (S505).

  When an entry having the same Remotecon ID 31, Session ID32, and Host ID33 (or 35) included in the message is registered in the selection candidate table, the message control unit 20 refers to the selection candidate table and stores the storage unit 19 A service selection table as shown in FIG. 15 stored in FIG. 15 is generated and registered for each set of available services.

  The service selection table includes items such as Remote ID 44, Session ID 45, Host ID (movement source) 46, Host ID (movement destination) 47, Service ID 48, Counter 49, and the like.

  The service selection table can be used in the processing device of the movement source (movement destination) Host ID 33 (or 35) when only the movement source Host ID 33 or the movement destination Host ID 35 is registered in the selection candidate table. When both the host IDs 33 and 35 of the transfer source and the transfer destination are registered from the service ID 34 (or 36), the registration is performed using the service IDs 34 and 36 that can be used by both the processing devices of the host IDs 33 and 35. (S502).

  Next, the message control unit 20 selects one candidate to be presented to the user from the records in the service selection table registered in S502. For example, the record having the smallest counter value 49 in the service selection table is selected (S503). Alternatively, priorities may be set for the services in advance, and selection may be made based on the priorities.

A service candidate notification message with the selected Service ID 29 as shown in FIG. 8E is transmitted to all the movement source (movement destination) processing devices related to the Remote ID 25 and the Session ID 26 included in the service selection request message ( S504).
As described above, the control device 5 performs the process of selecting a service.

  Assume that in the service candidate determination in the control device 5 in S403 of FIG. 13, a video-only service is selected and a service candidate notification message is transmitted to the processing device.

  The signal / message control unit 12 of the processing apparatus that has received the service candidate notification message from the network unit 13 extracts which service has been selected from the Service ID 29 of the service candidate notification message and displays it on the status display unit 15. An instruction to perform is given (S405).

  At this time, if the service desired by the user is presented by the status display unit 15, the operation is completed and the next operation is started. If the video service is not the service desired by the user, the user operates the instruction device 2 as in S401, and the instruction device 2 transmits a service selection signal to the processing device (S406).

  The processing device and the control device 5 perform the same processing as described above on the received service selection signal (S407 to S410). The processing is the same as the processing of S402 to 405, except that the service selection determination result and the service ID 29 of the message are different.

  In this case, it is assumed that a voice-only service is selected as a result of determination by the message control unit 20 of the control device 5. The user checks the status display unit 15 of the processing device, and completes the service selection operation if the desired service is displayed. When a service different from the desired service is presented, the same operation as S401 (S411) is performed, and another service is presented through the same procedure as S402 to S405 described above (S412 to 415).

It is assumed that the next selected service is all services.
Since the user desires to select all services, the user performs an operation via the input unit 6 of the instruction device 2 and transmits a movement execution signal to the processing device (S416).

  When the signal / message control unit 12 of the processing device receives the movement execution signal from the instruction device 2 via the directional communication reception unit 11, the signal / message control unit 12 generates a movement request message and transmits it to the control device 5 from the network communication unit 13. The message control unit 20 of the control device 5 that has received the movement request message from the network communication unit 18 recognizes that the service selection process has been confirmed, and confirms the flag of the service selection table in the storage unit 19 (S417).

  When the user repeatedly performs an operation so as to transmit a service selection signal to the instruction device 2, another service such as a video service, an audio service, or all services is selected and presented. When the service selection is completed, the same service is selected again.

  With the above procedure, the service that has passed the most time since it was last selected as the service to be moved or copied, or the service that arbitrarily set the priority, is selected. Service selection processing is possible.

  Even when there are a plurality of movable services, when all the services are moved, the service selection sequence of FIG. 13 can be omitted and executed.

[Move (copy) execution process]
The migration source processing device, the migration destination processing device, and the movable service are determined, and the message control unit 20 of the control device 5 sends the migration (duplication) possible message to the migration source processing device, the migration destination processing device, or the migration source processing device. And transmitted to the destination processing apparatus via the network communication unit 18. As shown in FIG. 8G, the service ID 29 of the confirmed service is included in the moveable (duplicatable) possible message.

  The signal / message control unit 12 of the processing device that has received the moveable (duplicatable) message from the network communication unit 13 instructs the status display unit 15 to display that the moveable (duplicated) is possible.

  In response to the display indicating that the movement (duplication) is possible on the status display unit 15 of the processing apparatus, the control unit 7 of the instruction apparatus moves (duplicates) the Signal ID 27 as a movement (duplication) execution by the user's operation. ) Generate an execution signal, and transmit the movement (duplication) execution signal from the directional communication transmitter 10 to the processing device.

  The signal / message control unit 12 of the processing device that has received the movement (duplication) execution signal via the directional communication reception unit 11 uses the Remotecon ID 25 and the Session ID 26 included in the received signal to send a movement (duplication) request message. It is generated and transmitted to the control device 5. The movement (duplication) request message is a message that is transmitted by the processing device that has received the movement (duplication) execution signal to notify the control device 5 that the movement (duplication) execution signal has been received.

  The message control unit 20 of the control device 5 that has received the movement (duplication) request message from the network communication unit 18 includes a storage unit and a processing unit for the movement source candidate and the movement destination candidate corresponding to the Remote ID 25 and the Session ID 26 included in the message. Judgment is made with reference to whether or not it is stored in 19 selection candidate tables.

  As a result of the determination, when the source device and destination candidate processing device for the message and the service to be moved are registered in the selection candidate table, the message control unit 20 of the control device 5 sets the source candidate or destination candidate. A movement (duplication) start message as shown in FIG. 8F is transmitted to the processing apparatus. The movement (duplication) start message is a message that the message control unit 20 of the control device 5 that has received the movement (duplication) request message transmits to the movement source (movement destination) processing device to start movement (duplication). It is. This message includes the Service ID 29 of the service that starts the movement (duplication) and the Host ID 30 of the processing apparatus of the movement destination (movement source).

  When either the source candidate or the destination candidate does not exist, the message control unit 20 of the control device 5 performs the Service as shown in FIG. A message that cannot be moved (replicated) including ID 29 is transmitted.

  If neither the movement source candidate nor the movement destination candidate processing device exists, the message control unit 20 of the control device 5 transmits an immovable message to the processing device that has transmitted the movement request message. When there are a plurality of devices that have transmitted the movement request message, a non-movable message is transmitted to all devices.

  The signal / message control unit 12 of the source (destination) candidate processing apparatus that has received the movement (duplication) start message outputs the message information to the service control unit 17, and the service control unit 17 includes the Host included in the message. It recognizes the processing device at the movement destination (movement source) from the ID 30, connects through the network, and performs processing necessary for movement.

  In the present embodiment, the explanation has been made on the premise of movement, but it is obvious that the same procedure can be realized in the case of duplication instead of movement.

[Second Embodiment]
Here, an example in which a plurality of services processed by a certain processing device are processed by separate processing devices will be described using the system configuration diagram of FIG. 16 and the service separation sequence of FIGS. 17 and 18.

  According to FIG. 16, a television C (processing device) 50 and a television D (processing device) 51 are installed close to each other, and a projector (processing device) 52 and an audio device (processing device) 53 are installed close to each other as well. Environment. It is assumed that the television C50 and the television D51 are capable of processing video and audio, respectively, and are currently executing movable processing. It is assumed that the projector 52 can only process video and can accept movement of processing from other processing devices. Further, it is assumed that the audio device 53 can only process audio and can accept movement of processing from another processing device, like the projector 52.

  In the above environment, the user uses the remote controller (instruction device) 2 to move the video output from the television C50 to the projector 52 and move the audio output from the television C50 to the audio device 53 for processing. In this embodiment, when the user moves a video from the television C50, it is assumed that the operation is performed in the order of designation of a source processing device, designation of a service, designation of a destination processing device.

  First, the user directs the pointing device 2 to the television C50 and performs an operation for transmitting a movement source selection signal via the input unit 6, and the control unit 7 of the pointing device 2 generates the movement source selection signal and performs processing. Send to. Since the television C50 and the television D51 are installed close to each other, the movement source selection signal reaches both devices even though the user transmits a signal to the television C50 (S601).

  The signal / message control unit 12 of the television C50 and the television D51 determines whether or not the service as shown in FIG. 12 can be provided (S602, 603), and the television C50 and the television D51 are also providing a movable service. Therefore, the signal / message control units 12 of the television C50 and the television D51 each transmit a source candidate registration message to the control device 5 (604, 608). At this time, since both the video service and the audio service are being processed on the television C50 and the television D51, the service ID 29 indicating the video service and the audio service is included in the movement source candidate registration message. The order in which the control device 5 receives the messages varies depending on factors such as the processing capability of each processing device, the load status and the delay time in the network, the processing capability of the control device, and the load status. In this embodiment, it is assumed that the message of the television C50 has arrived at the control device 5 first.

  The message control unit 20 of the control device 5 that has received the movement source candidate registration message from the television C50 from the network communication unit 18 performs the selection candidate table of FIG. 10 and the candidate of FIG. Since there is no record having the same Remotecon ID 25 and Session ID 26 in the device selection table, a source candidate registration message is selected from the television C50 where the message arrives early (605), and the selection candidate table and candidates are selected with the television C50 as the source candidate. The message information is stored in the device selection table, and at the same time, a source candidate notification message is transmitted to the television C50 (606).

  Note that the message control unit 20 of the control device 5 uses a counter or the like to move the source having the same Remote ID 25 and Session ID 26 as the Remote ID 25 and Session ID 26 included in the source candidate registration message from the television C 50 that has arrived first for a certain period of time. You may make it wait for a candidate registration message. When setting the reception waiting time, it is necessary to set a waiting time sufficiently long to receive a message from the television D51. If neither the television C50 nor the television D51 is registered in the candidate device selection table, the moving source candidate processing device is selected to have the earlier arrival time of the moving source candidate registration message at the control device 5. That's fine.

  The signal / message control unit 12 of the television C50 that has received the movement source candidate notification message notifies the user of the movement source candidate processing apparatus by the status display unit 15 (S607).

  The signal / message control unit 12 of the television D51 waits for the arrival of the source candidate notification message for a certain period of time by counting a counter or the like after transmitting the source candidate registration message (S608). The message control unit 20 of the control device 5 does not transmit a message because the television C50 has already been selected as the processing device of the movement source candidate (S609). The signal / message control unit 12 of the television D51 notifies the user by instructing and displaying the status display unit 15 that it is not a candidate because the movement source candidate notification message does not arrive for a certain time (S610).

  The user can confirm that the candidate selected as the movement source processing apparatus is the television C50 by looking at the status display unit 15 of the television C50. Since the television C50 is a processing device desired by the user as a movement source, the operation proceeds to the next operation. When the processing device desired by the user is not selected, the control unit 7 of the instruction device 2 transmits a movement source selection signal to the processing device by the user's operation, the same processing as described above is performed, and another processing device is Selected. By repeating such an operation, the selection of the processing apparatus is switched, and the user can select a desired processing apparatus.

  Next, the user performs an operation for selecting a video service from two services of video and audio that operate on the television C50. That is, an operation for transmitting the service selection signal to the instruction device 2 toward the television C50 is performed. The control unit 7 of the instruction device 2 generates a service selection signal and transmits the service selection signal from the directional communication transmission unit 10 (S611).

  The signal / message control unit 12 of the television C50 that has received the service selection signal from the directional communication reception unit 11 generates a service selection request message and transmits it to the control device 5 (S612).

  The message control unit 20 of the control device 5 that has received the service selection request message from the network communication unit 18 registers the information of the service selection request message in the service selection table of the storage unit 19 according to the procedure of the service determination flowchart of FIG. A service to be presented to the user is selected from the registered records in the selection table (S613).

  This time, the source processing device is registered, but the destination processing device is not registered, so a service candidate is selected from the record relating to the source processing device. In this case, it is assumed that the voice service is selected as a candidate. The message control unit 20 of the control device 5 transmits a service candidate notification message including information indicating that the voice service has been selected to the television C50 (S614).

  The signal / message control unit 12 of the television C50 that has received the service candidate notification message notifies the user by instructing and presenting to the status display unit 15 that the voice service has been selected as the selection candidate service (S615). .

  Since the service selection signal from the instruction device 2 has reached the television D51, the television D51 also transmits a service selection request message to the control device 5 (S616).

  However, since the television D51 is not registered in the selection candidate table stored in the storage unit 19 of the control device 5, an error occurs from the service determination flowchart of FIG. 14 (S617), and a candidate unselected message is transmitted (S617). S618).

  The signal / message control unit 12 of the television D51 that has received the candidate unselected message instructs the status display unit 15 to display that it has not been selected (S619).

  Since the voice service is not a service desired by the user, the user once again directs the pointing device 2 to the television C50 and performs an operation of transmitting a service selection signal via the input unit 6. Here, the same procedure as described above is performed, and the instruction device 2 generates a service selection signal and transmits it to the processing device (S620). The signal / message control unit 12 of the television C50 that has received the service selection signal generates a service selection request message and transmits it to the control device 5 (S621), and the message control unit 20 of the control device 5 this time A video service is selected (S622), and a service candidate notification message is transmitted to the television C50 (S623). The signal / message control unit 12 of the television C 50 that has received the service candidate notification message instructs the status display unit 15 to indicate that the video service has been selected (S624).

  Since the service selection signal from the instruction device 2 is also received by the television D51, the signal / message control unit 12 of the television D51 transmits a service selection request message to the control device 5 (S625). However, in the control device 5, since the television D51 is not registered in the selection candidate table as described above, an error occurs (S626), and a candidate unselected message is transmitted to the television D51 (S627). The signal / message control unit 12 of the television D51 instructs the status display unit 15 to display that it has not been selected (S628).

  Here, when the service desired by the user is not selected, the control unit 7 of the instruction device 2 transmits a service selection signal to the processing device by the user's operation, the same processing as described above is performed, and another service is Selected. By repeating such operations, the service selection is switched, and the user can select a desired service.

Since the video service is a service desired by the user, the user performs the following operation.
Through the operation so far, the video service having the television C50 as the movement source processing apparatus is selected as a candidate for movement.

  Next, in order to specify a destination processing apparatus, the user operates the pointing device 2 toward the projector 52, and the pointing device 2 transmits a destination selection signal (S629). It is assumed that the movement destination selection signal is received by the projector 52 and also by the adjacent audio device 53.

  The signal / message control unit 12 of the projector 52 and the audio device 53 that has received the destination selection signal transmits a destination candidate registration message to the control device (S630, S634).

  Here, since the service that can be processed by the projector 52 is only the video service, the video service is included in the Service ID 29 of the destination candidate registration message transmitted by the projector 52. Further, since the audio device 53 can process only the voice service, the voice service is included in the Service ID 29 of the destination candidate registration message transmitted by the audio device 53.

  Here, the message control unit 20 of the control device 5 that has received the destination candidate registration message from the projector 52 performs the processing of the device candidate selection flowchart of FIG.

  This time, since the video service is included in the Service ID 29 included in the destination candidate registration message from the projector 52, the projector 52 is selected as the destination candidate and registered in the selection candidate table (S631).

  The message control unit 20 of the control device 5 transmits a destination candidate notification message to the projector 52 (S632), and instructs the status display unit 15 that the projector 52 that has received the destination candidate notification message is a destination candidate. Is displayed to notify the user (S633).

  The signal / message control unit 12 of the audio device 53 that has received the destination selection signal also transmits a destination candidate registration message to the control device 5 (S634).

  The message control unit 20 of the control device 5 that has received the destination candidate registration message performs the processing of the device candidate selection flowchart of FIG. The message control unit 20 refers to the selection candidate table, and since there is no video service in the service included in the destination candidate registration message, the message control unit 20 is not selected as a candidate, and ends the process without notifying the audio device 53 (S635).

  The signal / message control unit 12 of the audio device 53 waits for reception of the destination candidate notification message for a certain period of time, but since there is no reception, the state display unit 15 is instructed to display that it has not been selected (S636). .

Here, the user recognizes that the desired device is selected by confirming the display of the status display unit 15 of the projector 52.
When the user operates the pointing device 2, the projector 52 transmits a movement execution signal (S637), and the movement execution signal is received by both the projector 52 and the audio device 53.

  Since the signal / message control unit 12 of the projector 52 has received the movement execution signal, it transmits a movement request message to the control device 5 (S638).

  The message control unit 20 of the control device 5 that has received the movement request message from the projector 52 is configured such that the processing device of the movement source candidate and the movement destination candidate corresponding to the Remote ID 25 and the Session ID 26 included in the message is the selection candidate table of the storage unit 19. It is determined with reference to whether it is stored in (S639). As a result of the determination, the information for moving the projector 52 is registered in the selection candidate table of the storage unit 19, so that the message control unit 20 of the control device 5 sets the television C 50 that is the source device for the projector 52. The movement start message is transmitted with the host ID 30 attached (S640).

  On the other hand, the signal / message control unit 12 of the audio device 53 that has received the movement execution signal also transmits a movement request message to the control unit 5 (S641).

  The message control unit 20 of the control device 5 that has received the movement request message from the audio device 53 is configured such that the processing device of the movement source candidate and the movement destination candidate corresponding to the Remote ID 25 and the Session ID 26 included in the message is the selection candidate of the storage unit 19. Judgment is made with reference to whether or not it is stored in the table (S642). As a result of the determination, since the movement information of the audio device 53 is not registered in the selection candidate table of the storage unit 19, the message control unit 20 of the control device 5 transmits an immovable message to the audio device 53 (S643). ).

The signal / message control unit 12 of the projector 52 that has received the movement start message connects to the television C50 through the network (S644), and starts the process of moving the video service between the projector 52 and the television C50 (S645).
The video service movement instruction process is completed by the procedure as described above.

  Next, a procedure for moving the voice service remaining on the television C50 to the audio device 53 will be described. The movement procedure will be described assuming that it is executed in the order of designation of a destination processing apparatus, designation of a source processing apparatus, and designation of a service.

  The user operates the pointing device 2 toward the audio device 53, and the control unit 7 of the pointing device 2 assigns an ID different from that in the video service moving instruction as the session ID 26 of the moving destination selection signal, and moves the moving device. A pre-selection signal is transmitted to the processing device (S646). Here, it is assumed that the destination selection signal is received because both the projector 52 and the audio device 53 are adjacent to each other.

  Since the projector 52 that has received the destination selection signal has already processed the video and cannot accept it as a destination candidate, the signal / message control unit 12 of the projector 52 determines that it cannot be accepted (S647). The status display unit 15 is instructed and displayed to notify the user that the selection signal has been received but cannot be accepted as the destination processing apparatus (S648).

  The signal / message control unit 12 of the audio device 53 that has received the movement destination selection signal determines that it is in an operable state as a movement destination candidate (S649), and the movable service is a voice service. The service ID 29 representing the voice service is included in the registration message and transmitted to the control device 5 (S650).

  The message control unit 20 of the control device 5 that has received the destination candidate registration message performs candidate selection processing similar to that for moving the video service described above after arrival of the destination candidate registration message from the audio device 53. The message control unit 20 selects Remote destination ID 25 and Session ID 26 of the destination candidate registration message from the audio device 53 as destination candidates because they are not registered in the selection candidate table and the candidate device selection table (S651). A destination candidate notification message is transmitted to (S652).

  The signal / message control unit 12 of the audio device 53 that has received the destination candidate notification message instructs the status display unit 15 to indicate that it is a destination candidate and notifies the user (S653).

  The user can confirm that the audio device 53 is selected as a destination candidate by checking the status display unit 15 of the projector 52 and the audio device 53. Since the audio device 53 is a device desired by the user, the process proceeds to the next movement source selection process.

  Next, the user operates from the input unit 6 of the instruction device 2 toward the television C50 to be processed as the movement source processing device, and the control unit 7 of the instruction device 2 transmits a movement source selection signal (S654). The transmitted movement source selection signal is received because both the television C50 and the television D51 are adjacent to each other.

  The television C50 that has received the movement source selection signal has moved the video service to the projector 52, so only the processing of the audio service is performed, and the television D51 performs the processing of two services of the video service and the audio service. It is determined whether these services are movable (S655, S656), and the television C50 and the television D51 each transmit a source candidate registration message to the control device 5. The movement source candidate registration message of the television C50 includes the Service ID 29 indicating the voice service, and the movement source candidate registration message of the television D51 includes the Service ID 29 indicating the video service and the voice service. Assume that these messages arrive at the control device 20 in the order of the television D51 and the television C50.

  The signal / message control unit 12 of the television D51 transmits a movement source candidate registration message to the control device 5 (S657).

  The message control unit 20 of the control device 5 that has received the movement source candidate registration message from the television D51 has a record having the same Remotecon ID 25 and Session ID 26 in the selection candidate table by the processing of the device candidate selection flowchart of FIG. Since the host ID 30 of the movement destination is registered in the record, the service in the selection candidate table matches the service included in the message, and the television D51 is not registered in the candidate device selection table. A source candidate registration message from is selected (S658). The information of the migration source candidate registration message is stored in the selection candidate table of FIG. 10 and the candidate device selection table of FIG. 11 with the television D51 as the migration source candidate, and at the same time, the migration source candidate notification message is transmitted to the television D51 (S659).

  Note that the message control unit 20 of the control device 5 uses a counter or the like to move the source having the same Remote ID 25 and Session ID 26 as the Remote ID 25 and Session ID 26 included in the source candidate registration message from the television D 51 that arrives first for a certain period of time. You may make it wait for a candidate registration message. If both the television C50 and the television D51 are not registered in the candidate device selection table, the one with the earlier arrival time of the migration source candidate registration message at the control device may be selected as the migration source candidate processing device. Good.

  The signal / message control unit 12 of the television D51 that has received the source candidate notification message notifies the user by instructing and displaying on the status display unit 15 that it is the source candidate processing device (S660). .

  The signal / message control unit 12 of the television C50 waits for the arrival of the source candidate notification message for a certain period of time by counting a counter or the like after transmitting the source candidate registration message (S661). The message control unit 20 of the control device 5 does not transmit the movement source candidate notification message because the television D51 has already been selected as the processing device of the movement source candidate (S662). The signal / message control unit 12 of the television C50 displays the message by instructing the status display unit 15 that it is not a candidate because the movement source candidate notification message does not arrive for a certain period of time, and notifies the user (S663).

  The user recognizes that the television D51 has become a movement source candidate by confirming the display of the television D51. However, since the television D51 is not the processing device desired as the movement source device, the instruction device 2 is again directed to the television C50 to transmit the movement source selection signal (S664). Similarly to the previous step, both the television C50 and the television D51 receive the movement source selection signal, and determine whether or not the movement source can be operated (S665, S666).

  The signal / message control unit 12 of the television D51 transmits a source candidate registration message to the control device 5 (S667). The message control unit 20 of the control device 5 that has received the source candidate registration message interrupts the processing for a certain period of time because the television D51 is registered in the candidate device selection table (S668).

  The signal / message control unit 12 of the television C50 also transmits a movement source candidate registration message to the control device 5 (S669). Since the television C50 is not registered in the candidate device selection table, the message control unit 20 of the control device 5 newly selects the television C50 as a source candidate (S670), and transmits a source candidate notification message to the television C50. (S671).

  The signal / message control unit 12 of the television C50 that has received the migration source candidate notification message notifies the user by instructing and displaying the status display unit 15 that it has become a migration source candidate (S672).

  On the other hand, the message control unit 20 of the control device 5 has interrupted the determination of the selection of the television D51, but proceeds to the next process after a predetermined time has elapsed. Since the source candidate notification message has already been transmitted, the process is terminated without transmitting the message to the television D51.

  The signal / message control unit 12 of the television D51 waits for the reception of the movement source candidate notification message for a certain period of time after transmitting the movement source candidate registration message to the control device 5, but does not receive the movement source candidate registration message. An instruction to display that it is not a selection candidate is given (S673).

Since the television C50 is a device that the user desires as a source processing unit, the operation proceeds to the next operation.
Next, the user performs an operation for selecting a voice service desired to be moved. The user operates the instruction device 2 toward the audio device 53 or the television C50, and the instruction device 2 transmits a service selection signal to the audio device 53 or the television C50 (S674). In the sequence diagram, it is assumed that a service selection signal is transmitted to the audio device 53. When transmitted to the audio device 53, the audio device 53 and the projector 52 receive the service selection signal.

  The projector 52 that has received the service selection signal transmits a service selection request message to the control device 5 (S675). However, since the projector 52 is not registered in the selection candidate table of the control device 5, an error occurs from the service determination flowchart of FIG. 14 (S676), and a candidate unselected message is transmitted (S677).

  The signal / message control unit 12 of the projector 52 that has received the candidate unselected message displays that the status display unit 15 has not selected (S678).

  The audio device 53 also transmits a service selection request message to the control device 5 (S679).

  The message control unit 20 of the control device 5 that has received the service selection request message from the audio device 53 refers to the selection candidate table and confirms that the destination candidate has been determined. Since the service ID 29 included in the service selection request message is included in both the movement information of the movement source processing apparatus and the movement destination processing apparatus, the message control unit 20 of the control apparatus 5 selects the voice service as a candidate (S680). Then, the service is registered in the item of Service ID (candidate) 37 of the corresponding record in the selection candidate table, and a service selection candidate message is transmitted to the audio device 53 (S681). The audio device 53 that has received the message notifies the user by instructing and displaying on the status display unit 15 that the voice service has been selected (S682).

  Since the voice service is a service desired by the user, the service is determined by performing the following operation.

  In the case of the above example, since there is only a voice service as a service that can be moved between these devices when the destination device and the source device are selected, it is not always necessary to select the service, and the transmission of the movement execution signal is immediately performed. May be performed.

  Finally, the user operates the pointing device 2 toward the television C50 or the audio device 53, and the pointing device 2 transmits a movement execution signal to the processing device.

  In the sequence diagram, the instruction device 2 is directed to the television C50, and a movement execution signal is transmitted (S683). Since the television C50 and the television D51 are adjacent to each other, both receive the movement execution signal.

  The television C50 and the television D51 that have received the movement execution signal transmit a movement request message to the control device 5 (S684, S687). However, as a result of the determination in the control device 5 (S685, S688), a movement request message for the television C50 is accepted, a movement start message is sent to the audio device 53 (may be the television C50) (S686), and the movement to the television D51 is performed. An impossible message is transmitted (S689).

  The signal / message control unit 12 of the audio device 53 that has received the movement start message outputs the message information to the service control unit 17, and the service control unit 17 connects to the television C50 through the network based on the message information (S690). The voice service transfer process is started between the audio device 53 and the television C50 (S691).

  By performing the above procedure, it is possible to move the video of the television C50 to the projector 52 and the sound of the television C50 to the audio device 53.

  That is, when there are a plurality of services in one processing apparatus, it is possible to move and copy in units of services with respect to another processing apparatus.
