(1) Create and transmit a transmission request for channel information of a television program being presented by the information presentation device to the information presentation device (first information presentation device 30) specified by the user in the user interface unit 43. , Get the channel information. (2) According to the channel information acquired in (1), the same TV program as the TV program being presented by the other information presentation device is received by the content acquisition unit 36 and presented to the content presentation unit 22.

Next, the operation of the first information presentation device 30 will be described with reference to the flowchart of FIG.

First, the user who is using the first information presentation device 30 selects a channel to be viewed using the channel selection button of the user interface unit 33 (S51). In response to this, under the control of the control unit 34, the content acquisition unit 36 selects and receives the video / audio information of the channel instructed by the user from the video / audio information of the plurality of televisions broadcast from the content distribution source 90. (S52), and the content presenting section 32 presents this (S53). In addition, channel information for identifying the presented channel is stored in the storage unit 35 (S5).
4). The processing up to this point is repeatedly executed each time the channel is changed.

Next, the first information presentation device 3 transmitted by another information presentation device (second information presentation device 40).
Waiting for reception of a signal requesting transmission of channel information of a television program being presented with 0 (S55).

Subsequently, when the transmission request of the channel information from the other information presenting apparatus (second information presenting apparatus 40) is confirmed (“YES” in S55), the control unit 34 causes the storage unit 3 to operate.
The channel information stored in 5 is read (S5

Next, using the flowchart of FIG.
The operation of the second information presentation device 40 will be described. In addition,
The operation in the case of watching regardless of the TV program being watched by the other information presenting apparatus (first information presenting apparatus 30) is as described above with reference to FIG. 9 (S51 to S53 in FIG. 9) and therefore omitted. Then, the operation of presenting the television program presented by the first information presentation device 30 to the second information presentation device 40 will be described.

First, the user who is using the second information presentation device 40 uses the user interface unit 43 to
An instruction for causing the second information presentation device 40 to present the television program presented by the first information presentation device 30 is input (S61). For example, the control unit 44, on the display screen which is the content presenting unit 42 of the second information presenting apparatus 40, the selection button a1 (FIG. 6) for selecting another information presenting apparatus.
May be displayed, and the user may be made to select and input using the user interface unit 43.

Next, the control unit 44, with respect to another information presenting apparatus (that is, the first information presenting apparatus 30) corresponding to the user's instruction input, the channel of the television program being presented by the information presenting apparatus. Make a request to send information,
This is transmitted via the communication unit 41 (S62). After that, the first information presentation device 30 is as described above (S in FIG. 9).
55 to S57) While operating, the second information presentation device 40 waits for a response from the first information presentation device 30 (S6).
3).

Next, the second information presentation device 40 receives the channel information sent from the first information presentation device 30 at the communication section 41 (S64). Then, under the control of the control unit 44, the content acquisition unit 46 receives the video / audio information of the television in accordance with the received channel information (S6).
5) The content is presented to the content presentation unit 42 (S66). For example, the video information of the television is displayed in the display area a2 (FIG. 6) of the display device of the content presentation unit 42. At this time, the control unit 44 stores the channel information specifying the presented channel in the storage unit 45.

As described above, in the cooperation system 2 of the information presentation device shown in FIG. 8, the information is transmitted in the order of →→→.

Next, with reference to FIGS. 11 and 12, a modification of the cooperation system of the information presenting apparatus will be described.

In the cooperative system 3 shown in FIG. 11, a relay device (information relay device) 60 for managing the channel information of each information presenting device is arranged between the information presenting devices 30 and 40 for transmitting and receiving the channel information. ing.

The relay device 60 includes at least a communication unit 61, a control unit 62, and a storage unit 63.

The communication unit 61 uses the first information presentation device 3
0 and the second information presentation device 40 are communicated. The communication method by the communication unit 61 may be wired or wireless.

The control unit 62 performs the following three processes in the relay device 60. (1) Each information presentation device (first
Of the information presenting apparatus 30), the channel information for specifying the channel presented by the information presenting apparatus is received, and the storage unit is associated with the identification information (ID) of the information presenting apparatus. Hold at 63. (2) A request for transmitting channel information of a television program presented by another information presentation device (first information presentation device 30) is received from the information presentation device (second information presentation device 40), and The channel information is acquired from the storage unit 63 based on the identification information (ID) of the other information presentation device included in the request. (3)
The channel information acquired in (2) is transmitted to the requesting information presentation device (second information presentation device 40).

Further, as shown in FIG. 11, the distribution device 95
May be arranged between the content distribution source 90 and each of the information presentation devices 30 and 40. As a result, the television signal from the content distribution source 90 can be shared by the information presentation devices 30 and 40.

As described above, in the cooperative system 3 of the information presenting apparatus shown in FIG. 11, information is transmitted in the order of →→→→.

Further, the cooperation system 4 shown in FIG.
Between the first information presentation device 30 (FIG. 8) that can directly acquire the video and audio information of the television from the content distribution source 90, and the second information presentation device 20 (FIG. 1) that can be acquired via the base station 50. This is a form of taking over.

In the cooperation system 4, the base station 50 first receives the channel information specifying the channel presented by the information presenting apparatus 30, which is sent from the first information presenting apparatus 30. , And stores it in the storage unit 54 in association with the identification information (ID) of the information presentation device 30. Next, the first information presentation device 3
The identification of the information presenting apparatus 30 from the storage unit 54 with respect to the second information presenting apparatus 20 that has requested the transmission of the channel information of the information presenting apparatus 30 in order to take over and present the television program that 0 is presenting. According to the channel information acquired based on the information (ID), the video / audio information of the designated channel is received and transmitted. In this case, FIG.
In the cooperation system 4 of the information presentation device shown in, → →
Information is transmitted in the order of → →.

Further, in the above-mentioned cooperation system 4, the base station 50 acquires the channel information from the first information presentation device 30 at the time of receiving the takeover request from the second information presentation device 20, Information presentation device 30
The television program presented by the user may be provided to the second information presentation device 20. In this case, in the cooperation system 4 of the information presentation device shown in FIG. 12, the information is transmitted in the order of →→→→.

As still another mode, a user's input operation for designating which information presenting device is to be taken over, acquisition of channel information from the information presenting device of the takeover source, acquisition and takeover of video / audio information of the television. The server device such as the base station 50 performs all control processing such as transmission to the above information presenting device, and each information presenting device which is a terminal device only presents the audiovisual information acquired from the server device. Good. According to this aspect, since each information presentation device only presents the content transmitted from the server device, the configuration of the information presentation device can be simplified.

As another form, the content proxy acquisition unit 52 of the base station 50 may be a separate device. Then, when the control unit 53 receives the takeover request from the second information presentation device 20, the control unit 53 refers to the storage unit 54 to specify the channel information, and the content proxy acquisition unit 52.
May be requested to acquire and transmit the video and audio information to the second information presentation device 20.

Depending on the content, the content data accumulated in the base station 50 may be provided to each information presentation device.

Up to this point, the first information presenting apparatus 10 or 30 which is the takeover source presenting the television program first and the second information presenting apparatus which is the takeover destination presenting the television program afterward are presented so far. 20 and 40 have been described.
However, it is desirable that each of the information presentation devices that form the cooperation system have both a function as a takeover source that transmits channel information and a function as a takeover destination that requests takeover. Of course, an information presenting device having only one of the functions is also possible.

Further, in FIG. 8, the second information presenting apparatus 40 requests the first information presenting apparatus 30 for the video / audio information of the currently presented TV program instead of requesting the channel information. Good. In other words, the second information presentation device 40 uses the audiovisual information received by the content acquisition unit 36 of the first information presentation device 30 as the content presentation unit 42.
May be presented at.

Up to this point, the second information presentation device 2
When watching a television program at 0, 40, the first information presenting device 10, 30 is presenting the television program, and the presenting television program is taken over and presented to the second information presenting device 20, 40. I've explained about the case.

However, if the base station 50, the relay device 60, and the like (hereinafter sometimes referred to as “cooperation management device”) are used, the first information presentation device 1 that is the takeover source.
The second information presentation device 2 regardless of the states of 0 and 30.
It is possible to take over to 0, 40.

Specifically, the channel information of the television program presented by the first information presentation device 10, 30 is stored in the storage unit 54 of the base station 50 or the storage unit 63 of the relay device 60 immediately before the power is turned off. Let As a result, even if the power of the first information presentation devices 10 and 30 is turned off or moved to a position where communication is not possible before the second information presentation devices 20 and 40 are activated, the second information presentation devices 20 and , 40
The channels presented by the first information presentation devices 10 and 30 can be taken over.

Further, the first information presentation devices 10 and 30 are
The channel information of the presented TV program may be stored in the storage unit 54 of the base station 50 or the storage unit 63 of the relay device 60 at any timing. Then, this process may be performed at the time when the user gives an instruction via the first information presentation device 10, 30 or another device such as the base station 50.

For example, the second information presentation devices 20, 4 will be described later.
The channel information of the channel that the user wants to watch at 0 is transmitted from the first information presentation device 10 or 30 to the base station 50 as a reservation of a takeover request, and is stored in the storage unit 54 of the base station 50 or the storage unit 63 of the relay device 60. Remember. Thereby, when the second information presentation device 20, 40 takes over the channel presented by the first information presentation device 10, 30, the first information presentation device 10, 3
The value 0 is not limited to the channel currently being presented or the channel being presented immediately before the power is turned off, and it is possible to more flexibly select the channel to be taken over. Of course, the storage unit 54 of the base station 50 and the storage unit 63 of the relay device 60
Can record a plurality of channel information of the channels presented by the first information presentation devices 10 and 30.

As described above, when the channel information is directly exchanged between the information presenting devices (FIG. 8), it is sufficient that they can communicate with each other when taking over. Further, if a relay server device such as the base station 50 or the relay device 60 is used (FIGS. 1, 11, and 12), even if the first information presentation device that is the transfer source cannot communicate at the time of transfer. Good. Further, by centrally managing the channel information in the relay server device, the procedure of handing over the contents is simplified.

Further, the information presenting apparatus cooperation system described above has a function of allowing each information presenting apparatus to perform personal authentication by using a password, a voiceprint, a fingerprint, a face or the like (authentication units 17, 2).
7 (FIG. 1) and the authentication units 37 and 47 (FIG. 8) may be incorporated to manage the TV program (or channel) being viewed by each user.

For example, in FIG. 1, not only the identification information of the first information presentation device 10 and the channel information but also the identification information of the user acquired by the authentication unit 17 are stored in the storage unit 54 of the base station 50. Remember. And
When the user activates the second information presenting apparatus 20 and requests the takeover of the presentation by the other information presenting apparatus, in the second information presenting apparatus 20, the authentication unit 27 authenticates the user and The identification information of a certain user is transmitted to the base station 50. In response to this, the base station 50 identifies the first information presentation device 10 that the user was viewing from the storage unit 54 based on the identification information of the user, and extracts the corresponding channel information. As a result, the user does not need to be aware of the confirmation procedure shown in FIGS. 6 and 7 when operating the second information presentation device 20, and the first information presentation device that has been viewed until then. 10 can be automatically selected to continuously watch TV programs and the like.

Further, the information (content) to be taken over has been described so far as the video / audio information of the television. However, the present invention is not limited to this, and the information presenting device and the cooperation system thereof can be applied to image information, audio information, and any other information as long as the information can be effectively transferred between the devices.

For example, the information presenting apparatus and the cooperation system thereof can be utilized also when it is desired to listen to the same program as a radio program listened to on a portable radio in stereo. Further, a personal computer may be used as the information presenting device and a homepage or the like browsed on the Internet may be taken over as the content.

Further, a plurality of contents may be handed over at one time. As a result, even if, for example, the screen of the takeover source personal computer is divided and different contents are displayed on the respective divided screens (frames), the personal computer of the takeover destination can take over. Further, even when the AV device of the takeover source separately acquires the video-only content and the audio-only content and presents them simultaneously, the takeover destination AV device can take over.

The information presenting device and its cooperation system can be optimally configured according to the contents to be presented. In other words, the information presenting device and the devices that form the cooperation system thereof may be devices corresponding to the content.

For example, if the content is a television program as described above, a television station or the like is used as the content distribution source,
An information presenting apparatus is configured as a television apparatus capable of presenting video / audio information of a television. If the content is FM broadcast, the FM broadcast station or the like is used as the content distribution source.
The information presenting device is configured as a radio or stereo capable of presenting broadcasting. Further, if the content is information distributed by a computer network, the information presenting apparatus is configured as a personal computer, a PDA, a mobile phone or the like capable of presenting a homepage etc. by using a provider, a server apparatus or the like as a content delivery source.

If the content is FM broadcast, the content proxy acquisition section 52 (FIG. 1) of the base station 50 or the content acquisition section 36 of the first information presentation device 30.
(FIG. 8) includes an external interface such as an antenna. If the content is a homepage or the like, the content proxy acquisition unit 52 and the content acquisition unit 36 described above.
Is a modular line, cable internet line, A
It has an external interface such as a DSL line.

The transmission medium for communication between the content distribution source and the cooperation system of the information presenting apparatus (for example, between the content distribution source 90 and the base station 50) is arbitrary as long as the content data can be transmitted. Similarly, the medium for transmitting the content data in the cooperation system of the information presenting device is arbitrary as long as the content data can be transmitted. Further, the medium for transmitting the content designation information in the cooperation system of the information presenting device is arbitrary as long as the content designation information can be transmitted. In the cooperation system of the information presenting device, the medium for transmitting the content data and the medium for transmitting the content designation information may be the same or different.

Specifically, the transmission medium is IEEE1.
394, USB (universal serial bus), power line carrier, cable TV line, telephone line, ADSL (asymmetric)
Digital subscriber line) IrD, even if wired such as line
Infrared like A (infrared link access protocol) and remote control, Bluetooth, IEEE802.1
One wireless, HDR (High Data Rate), mobile phone network, satellite line, terrestrial digital network, or the like may be used.

Further, the locations where the link management devices such as the base station 50 and the relay device 60 are installed are arbitrary. That is, the cooperation management device may be installed at home or on a public network such as the Internet. If you install the above cooperation management device in your home,
In the home, there is no communication cost for communication between the cooperation management device and each information presentation device, and a problem is unlikely to occur in terms of security.

On the other hand, if the cooperation management device is installed in a place where an unspecified number of people can share it, such as a public network, it becomes possible to transfer contents between the device inside the home and the device outside the home. For example, content can be handed over between a device in a home and a device in an airplane or an automobile. Also,
Not only in the closed world of the home, but also in a specific group or an unspecified number of people, the content can be handed over. Even if the cooperation management device is at home, it can be made to appear as if it is outside the home by permitting access from outside the home by a specific group or an unspecified number of people.

Although not shown in FIG. 1, FIG. 8, FIG. 11, and FIG. 12, a server device or the like may be provided in order to realize communication in the cooperative system of the information presenting device. Further, a device that relays communication may be provided between each device. Furthermore, a plurality of communication methods may be mixed in the above-mentioned cooperation system.

As described above, the cooperation system of the information presenting apparatus is intended to take over and present the contents among the plurality of information presenting apparatuses. Therefore, the form (topology) of the cooperation system of the information presentation device can be appropriately selected in consideration of the convenience of actual operation. Of course, the present embodiment is not limited to the form shown in the drawings.

Further, the content designation information for controlling the transfer of content is channel information if the content is, for example, a television program as described above, and FM.
Frequency is used for broadcasting, and address information is used for homepages on the Internet. That is, the format of the content designation information transmitted between the information presentation devices is appropriately selected according to the content to be inherited.

Furthermore, in the cooperation system of the above information presenting apparatus, accompanying information such as environment for presenting the content may be transmitted together with the content specifying information for specifying the content. For example, even if setting information such as screen division and sound balance used for presenting content in the information presenting device of the takeover source is transmitted together with the content designation information as control information to the information presenting device of the takeover destination. Good. As a result, in the information presentation device of the takeover destination, it is possible to present the content by reproducing the environment set in the information presentation device of the takeover source as much as possible. Of course, in the information presentation device of the handover destination, it is possible to construct the presentation environment by modifying the received control information according to the hardware configuration of the information presentation device.

Further, according to the cooperation system of the information presenting apparatus, a wider variety of operation procedures (scenarios) are possible when handing over contents.

For example, the power of the second information presentation device is turned on.
Then, after the transfer of the content from the first information presenting apparatus is completed, the second information presenting apparatus transmits a power-off command to the first information presenting apparatus, whereby the first information presenting apparatus Can be turned off. Further, the above command may be sent from a server device such as the base station 50 or the relay device 60. In addition, the first information presentation device may turn off the power supply itself after the content is handed over to the second information presentation device. Furthermore, a command may be transmitted from the first information presentation device to the second information presentation device, which is the takeover destination, so that the power is automatically turned on to take over the content.

In addition, there is a case where the content is taken over from the first information presentation device to the second information presentation device, and then it is desired to present the content again by the first information presentation device. In that case, the first information presentation device can present the original content by holding the content designation information of the content handed over to the second information presentation device. This is particularly effective when the first information presentation device presents content different from the content handed over to the second information presentation device. Moreover, since it is not necessary to transmit the content designation information, the communication amount can be reduced. When the second information presentation device presents content different from the content taken over from the first information presentation device, the first information presentation device takes over the content according to the procedure described in the above embodiment. Of course it is possible.

Further, in the above embodiment, the case where the first information presentation device and the second information presentation device always have a one-to-one relationship has been described, but the present invention is not limited to this. That is, in the cooperation system of the information presenting apparatus according to the present invention, there are various variations such as a case where the first information presenting apparatus and the second information presenting apparatus have a relationship of 1: N, N: 1, N: N. Is possible.

For example, in the case of 1-to-N, a plurality of people can share the content being presented by a certain one of the information presenting apparatuses, so that the plurality of persons can share the content. That is, more people can enjoy attractive content at the same time.

Further, in the case of N: 1, a plurality of contents individually presented by a plurality of persons on each information presenting apparatus are collectively presented on one information presenting apparatus, so that all persons can obtain one information. The presentation device can share the content of each person. At that time, if the content is video information of a TV or the like, it is easy for everyone to watch if the content is taken over and presented to the TV having the largest screen. Of course, you can take over to a terminal with a small screen for individuals. In addition, such a form in which a plurality of contents are collectively presented on one information presentation device can also be used for monitoring what content each person is presenting.

As described above, according to the above information presenting apparatus and its cooperation system, for example, when watching a movie or sports on a television with a small screen size installed in the bedroom, the climax is reached. Therefore, even if you feel like watching on a large-screen TV in the living room, there is no need to work to match the channels on the TV in the living room to the channels you have watched on the TV in the bedroom.

Further, according to the above information presenting apparatus and its cooperation system, it is possible to take over the contents presented in the past in the information presenting apparatus of the takeover source to the information presenting apparatus of the takeover destination.

Further, according to the above information presenting apparatus and its cooperation system, the contents can be selectively taken over by recording a plurality of channel information.

Further, according to the above information presenting apparatus and its cooperation system, by authenticating the user,
The operation of handing over content can be automated.
