[0013]
DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 is a diagram showing a system environment employed by a user terminal remote control method and system according to the present invention.
Here, a guide server that exchanges information with a plurality of content servers 2, 3, 4, user terminals (clients) 5, 6, and clients 5, 6 that provide WWW (World Wide Web) content and services on the Internet 1. 7 and a guide management client 8 that operates the clients 5 and 6 via the guide server 7.
[0014]
The guide management client 8 controls the clients 5 and 6 connected to the guide server 7 by a human or an automatic program. Here, when the guide management client 8 is controlled by an automatic program, this program is referred to as a guide management program.
[0015]
The clients 5 and 6 are connected to the content servers 2, 3, and 4 under the control of the guide server 7, and access the content and services on the content servers 2, 3, and 4. At this time, the timing at which the plurality of clients 5 and 6 connected to the guide server 7 access the content is controlled by the guide server 7.
The guide server 7 monitors the clients 5 and 6 so that the connected clients 5 and 6 can access the plurality of content servers 2, 3 and 4 in a planned manner, and connects according to the instructions of the guide management client 8. The clients 5 and 6 are controlled.
[0016]
The configuration of the guide server 7 is shown in FIG. The guide server 7 receives access control information from the client control interface 71 for exchanging data with the clients 5 and 6, the guide control interface 72 for exchanging data with the guide management client 8, and the content server 2 (3, 4). It has a content server interface 73.
The client 5 (6), the guide management client 8, and the content server 2 (3, 4) use the function of the guide server 7 via these interfaces 71 to 73.
[0017]
The program sheet 74 is data in which the contents of navigation provided by the guide server 7 are recorded. The program sheet 74 is information related to the content of the content server 2 (3, 4) and a method of accessing the plurality of content servers 2 (3, 4). The timing is recorded.
Access to the program sheet 74 is via the program management device 75. The program progress status storage device 92 represents the progress status of the service provided by the program sheet 74. The program sheet 74 records the service schedule, while the program progress state storage device 92 is data recorded about the contents of the service actually provided and access control data of the content server.
The guide management client 8 controls the progress of the program according to the program progress state and the state of the client 5 (6).
The client status storage device 91 represents the status of the client 5 (6) operating on the navigation user's terminal.
[0018]
The client control software 93 is a user terminal control program transferred to the user terminal 5 (6) by connecting to the guide server 7. The client control software 93 is the same as what is called a client operating on the user's terminal. When the client is not installed in the user terminal in advance, the client control software 93 transfers the software when connected to the guide server 7 and is executed on the user terminal.
When the guide server 7 is provided as a web server, the delivery execution mechanism can be easily realized as a Java applet (an application program created in a programming language developed by Sun Microsystems, Inc.).
[0019]
The client software 94 is software that is required when using the content and services on the content server 2 (3, 4). Similarly to the client control software 93, the client software 94 is transferred from the guide server 7 to the user's terminal and executed as necessary.
[0020]
The program management device 75 manages the program sheet 74 and exchanges the program sheet 74 with other devices. The navigator manages and operates the program sheet 74 on the guide server 7 by registering, changing, and deleting the program sheet 74 via the guide control interface 72.
The program distribution device 76 distributes the client control software 93, the client software 94, and the program sheet 74 in accordance with a request from the user's terminal.
[0021]
The user acquires the program sheet 74 corresponding to the navigation in which the user participates from the program distribution device 76 via the client control interface 71 from the client 5 (6). The client state monitoring device 77 acquires the client state transmitted from the client 5 (6) operating on the user terminal via the client control interface 71 and stores it in the client state storage device 91. The client status storage device 91 is managed for each provided program sheet 74 unit (navigation), and is used for grasping the status of the client of the navigation user.
The client control device 78 operates the client 5 (6) of the navigation user's terminal to access the content and services on the content server 2 (3, 4). Since the content access method is recorded in the program sheet 74 on the client 5 (6), the client control device 78 need only give the client 5 (6) a trigger for content access.
[0022]
In addition, a change in the content and service on the content server 2 (3, 4) or a change in the program sheet 74 accompanying a change in the provided time is sent from the client control device 78 to the client 5 (6). It is done. This is because the occurrence of the change is transmitted to the client 5 (6) in real time and the program of the client 5 (6) is advanced.
[0023]
The guide control device 79 manages the progress of the program, and transmits the progress of the program to the client control device 78 in accordance with the access control information from the content server 2 (3, 4) and the request of the guide management client 8.
The client control device 78 informs the guide control device 79 whether or not the client 5 (6) is ready to proceed with the program.
[0024]
The configuration of the guide management client 8 is shown in FIG.
In FIG. 3, the guide management client 8 has a user interface 83 with a program management device 81, a guide control device 82, and a guide 90 that exchange data with the guide server 7.
The navigator uses the function of the guide management client 8 via the user interface 83. When planning a navigation, the program management device 81 creates a program sheet 74 via a user interface 83 with a navigator, and registers, changes, and deletes the program sheet 74 in the guide server 7. When the navigation is performed, a program sheet 74 for program progress is received from the guide server 7.
[0025]
If the program sheet 74 is updated due to a request from the navigator during the navigation, the change is transmitted to the guide server 7 together with the update of the program sheet 74 of the guide management client 8.
The guide control device 82 advances the navigator based on the progress state of the program sent from the guide server 7. The navigator controls the guide control device 83 via the user interface 83 of the guide management client 8. The guide management client 8 accesses the content server 1 (3, 4) in the same manner as the client 5 (6). Therefore, the guide control device 82 controls the external content access device 80 (web browser, stream reproduction software, etc.). At this time, the content access device 80 uses the access method recorded in the program sheet 74 and synchronizes with the program progress of the client 5 (6).
[0026]
The configuration of the client 5 (6) is shown in FIG. For example, the client 5 has a program management apparatus 51 that exchanges data with the guide server 7, a client control apparatus 52, and a user interface 53 with the guide 90.
As described above, the client 5 is installed and executed in advance on the user's terminal, or transferred and executed when accessing the guide server.
The program management device 51 receives a program sheet 74 for advancing a program from the guide server 7 when performing navigation. If the program sheet 74 is updated due to a request from the navigator during the navigation, the change of the program sheet 74 is transmitted to the client 5 via the guide server 7 and the program sheet 74 on the client 5 is updated.
[0027]
The user can check the contents and progress of the program via the user interface 53. The client control device 52 accesses the content server 2 (3, 4) in accordance with a program progress trigger sent from the guide server 7. As with the guide management client 8, the client control device controls the external content access device 80.
[0028]
FIG. 5 is a flowchart showing an operation flow until the user terminal is connected to the guide server 7 and the content server 2 (3, 4) can be accessed. In FIG. 5, when the user connects to the guide server 7 from the terminal (step S501), the program distribution device 76 on the guide server 7 distributes the client control software 93 on the terminal (step S502). In the user terminal, the client control software 93 is executed and becomes resident while participating in navigation (step S503).
[0029]
Next, the user requests the corresponding program sheet 74 from the guide server 7 by selecting the navigation to participate in the state where the client 5 (6) is activated (step S504). This means that the participant can select navigation via the graphical interface of creat 5 (6).
The guide server 7 transmits the corresponding program sheet from the program sheet 74 managed by the guide server 7 according to the request of the client 5 (6) (step S505), and registers the information of the client 5 (6) in the guide server 7. (Step S506).
[0030]
The client 5 (6) receives the program sheet 74 and registers the program sheet 74 by the program management device (step S507). Thereafter, the client 5 (6) monitors the state of the client 5 (6) (step S509), and transmits it to the guide server 7 periodically or when the state is changed (steps S509 and S510). In addition, the client 5 (6) is waiting to receive client control information such as program progress from the guide server 7 and change of the program sheet 74 (step S511).
[0031]
When control information is received from the guide server 7 (step S512), the client control device 78 interprets and executes the control information to operate the client 5 (6) (step S513).
Note that the processing from step S508 to S510 described above and the processing from step S511 to S513 are performed in parallel.
[0032]
FIG. 6 is a flowchart showing the process flow until the navigator terminal connects to the guide server 7 and the program can be prepared for progress.
In FIG. 6, the navigator is connected to the guide server 7 from the terminal in the same manner as the user's terminal in the same manner as the preparation procedure of the client 5 (6) (step S601). The client control software 93 is distributed (step S602). The client control software 93 has a navigator guide server control device.
The client control software 93 is executed at the terminal of the navigator (step S603), and becomes a resident state during navigation execution.
[0033]
Next, the guide 90 requests the corresponding program sheet 74 from the guide server 7 by selecting the navigation to be controlled while the guide management client 8 is activated (step S604). The guide server 7 transmits the corresponding program sheet from the program sheet 74 managed by the guide server 7 in accordance with the request of the guide management client 8 (step S605).
[0034]
The guide management client 8 receives the program sheet 74 and registers the program sheet 74 with the program management apparatus 81 (step S606).
Thereafter, the guide management client 8 waits to receive the connection status of the client 5 (6) and the progress status of the program from the guide server 7 (step S607), and receives these periodically or when the status is changed ( Steps S608 and S610) and displayed on the guide management client 8. Further, the guide management client 8 enters a state of waiting for the progress control of the program of the guide 90 (step S610), and when the navigator performs control, transmits the operation of the navigator to the guide server 7 (steps S611 and S612). proceed.
Note that the processes from step S607 to S609 and the processes from step S610 to S612 are performed simultaneously in parallel.
[0035]
The access control from the client 5 (6) to the content server 2 (3, 4) by the guide server 7 will be described with reference to the flowchart shown in FIG. As described above, the client 5 (6) transmits the state of the user's terminal to the guide server 7 periodically or at the time of change (step S701). The state of the client 5 (6) is monitored by the client state monitoring device 77 of the guide server 7 (step S702) and recorded in real time on the client state storage device 91. The client control device 78 refers to the contents of the client state storage device 91, and when the state of the client 5 (6) participating in the same navigation is in the program progress wait state (in step S703, all clients wait for the program progress). Whether or not the program can proceed is notified to the guide control device 79 (step S704).
[0036]
When there are contents and services that can be processed by the program (step S705), the guide control device 79 waits for an access permission to be transmitted from the contents server 2 (3, 4) (step S706). This standby state is executed only in the case of the content server 2 (3, 4) having an irregular start time, and does not occur for the content server 2 (3, 4) having a regular start time and free access timing. Whether or not this standby state is required is recorded as content information of the program sheet 74.
[0037]
When access to the content server 7 is possible (step S707), the navigator proceeds with the program after confirming the state of the client 5 (6) (step S708). The guide control device 79 of the guide server 7 notifies the client control device 78 of the program progress (step S709), and the guide server 7 transmits the program progress notification to the client 5 (6).
The client control device 52 of the client 5 (6) obtains the access method to the content server 7 to be executed next with respect to the program management device 51 by the program progress notification (step S710). The client control device 52 operates the content access device 80 according to this access method (step S711).
The client control device 52 of the client 5 (6) monitors the content access device 80, and notifies the guide server 7 of the program progress waiting when the access is terminated (step S712).
[0038]
In the process of step S705, if there is no content to be continued in the program, the navigator notifies the client control device 52 of the end of the program from the guide management client 8 (steps S713 and S714), and the program ends from the guide server to the client 5 (6). Is transmitted, and the client ends (step S715).
[0039]
A flow of processing for registering the program sheet 74 from the guide management client 8 to the guide server 7 is shown in a flowchart in FIG.
In FIG. 8, first, the navigator creates a program sheet 74 on the guide management client 8 (step S801). When the creation is completed, the program sheet 74 is transmitted from the guide management client 8 to the guide server 7 (step S802). The guide server 7 registers the received program sheet 74 in the guide server 7 by the program management device 75 (step S803).
The update and deletion of the program sheet 74 uses the same interface, calls the program sheet 74 registered in the guide server 7 from the guide management client 8 and operates it.
[0040]
FIG. 9 is a flowchart showing the flow of processing for changing the program sheet 74 being navigated from the guide management client 8.
In FIG. 9, first, the navigator changes the program sheet 74 being navigated on the guide management client 8 (step S901). After the change is completed, the navigator transmits the changed portion of the program sheet 74 from the guide management client 8 to the guide server 7 (step S902).
[0041]
When receiving the changed portion, the guide server 7 transfers the changed portion from the guide control device 82 to the client control device 52 (step S903). The client control device 52 transmits the changed part of the program sheet 74 to the client 5 (6) participating in the same navigation (step S904).
Upon receiving the changed part of the program sheet 74, the client control device 52 of the client 5 (6) transfers it to the program management device 51 (step S905). The program management apparatus 51 registers this changed part in the client 5 (6), and the change of the program sheet 74 is completed (step S906).
