In field such as the electric device that satisfies the needs of consumers of household electrical appliance, developed the infrared remote controller that for example adopts the amplitude modulation scheme, as being used to make the user can be, and have been popularized to the device of the long-range input operation order of described device.Use that ultrared communication means has cheaply, little power consumption, be not subjected to the advantage of legal restrictions or the like in various countries.This communication means does not need wiring,, does not need the connector of stube cable that is, has therefore reduced cost.In addition, described device is not subjected to owing to adhering to/remove the mechanical wear that connector causes in order to connect/to disconnect to connect.
But, utilize ultrared communication means to have the problem of directivity.When the light receiving part of receiver was not aimed in the angular field of view of transmitter, communication can not be set up.This becomes a very big constraint (referring to for example Japanese Unexamined Patent Application publication number No.2002-165281).Because the infrared communication method is the one-way communication method basically, transmitter can not receive answer from receiver,, can not confirm the result of transmitting that is.
Being used for the interactive home network that connects family's information household appliances nowadays permeates on family market.For example, a kind of seamless and network system that can interactive mode be connected of DLNA (the live alliance of digital network) suggestion wherein, is utilized any household electrical appliances (referring to the website of for example DLNA), the user can any at home position enjoy content simply and easily.According to this system, can be stored in any device in the network such as the information of AV content.That is, the user not only can watch the AV content in the room at the device place of memory contents, and can be watching with irrelevant other rooms of content location of separating with above-mentioned room, thereby can strengthen user friendliness.
We expect that these devices that are suitable for the DLNA criterion will use more widely, have increasing device to be supported to be used for network.When the quantity of the device of network-ready increases, can come execute script to utilize the Long-distance Control of these devices of infrared communication execution by control point (hereinafter being also referred to as " IP remote controllers ").The IP remote controllers utilize IP network at the network upper controller, and described IP network does not almost have the constraint (referring to for example Japanese publication No.2005-17439, it has been transferred to applicant of the present invention) of directivity and communication range.
Under the situation of infrared remote controller, when controlled device was not aimed at the angular field of view of infrared remote controller, because the restriction of directivity, described device can not be operated.Otherwise described controlled device can easily be specified and visually be checked.On the contrary, under the situation of device, when the user wants to control the device that is positioned at his or she front, owing to be not only the device that is positioned at his or she front by the control of IP remote controllers, and also have other devices typically to be controlled, so user's said apparatus of having to specify pretty troublesomely.
Be present at a plurality of controllable devices under the situation of a network, controlled device can be specified according to the following processing that utilizes the network service interactivity: the IP remote controllers send a predetermined command on network; Determine whether that response sends from any device on the network; Determine that the result is presented at the GUI of IP remote controllers (graphic user interface) and goes up (referring to for example Japanese Unexamined Patent Application publication number No.2003-330827, Fig. 8).But, can not determine that whether the device that is presented on the GUI really is that the user wants the device controlled at this moment.Whether desired controlled device is only correctly specified just can be determined after the IP remote controllers have been launched an order, and this order is made the request of an executable operations to being presented at device on the GUI, then, carries out requested operation by described device.
When showing that each device has wherein all sent device tabulation to the response of this order, the user can understand current available device, and is selecting to select a device on the screen at an easy rate.But when devices all on the network all was listed on the selection screen, the user was difficult to specify the device of his or she in front.

Fig. 4 A shows the configuration block diagram according to the device of operating as controlled device in the tele-control system of this embodiment.In the example shown in this figure, controlled device is as network (or DLNA)-ready hdd recorder, its selection and write down the content of the broadcasting of for example television broadcasting.
Selectively, with reference to figure 4B, controlled device is as television receiver, and its outside port by hard-disk interface 65 is connected to external fixed disk drive 66, and is provided with display and loud speaker.
The broadcast wave that receives by the antenna (not shown) is provided for tuner 51.Tuner 51 is selected a broadcast wave according to the instruction of CPU 61 on predetermined channel, export received data in the stage subsequently to demodulator 52 then.The digital modulated data that demodulator 52 demodulation are received.
By the numerical data of demodulation for example is transport stream (TS), wherein is re-used according to compressed AV data of MPEG-2 system and programme information.TS decoder 53 is explained described transport stream, then transport stream is separated into AV data and programme information according to the MPEG-2 system compresses.Subsequently, TS decoder 53 sends described AV data to AV decoder 54, and sends programme information via bus 58 to CPU 61.
When the real-time AV data that receives from TS decoder 53 according to the MPEG-2 system compresses, AV decoder 54 becomes the video data of compression and the voice data of compression with the AV data separating.The video data of compression de-compresses into raw video signal by AV decoder 54 according to the MPEG-2 system.Voice data is synthesized the audio signal that will be reset with the sound that adds then by PCM (pulse code modulation) decoding.The vision signal that will be reset is output on the display via multiplexer 55B.The audio signal that will be reset is output on the audio reproducing apparatus via multiplexer 55A.Under the broadcasted content situation of the program that is programmed to be recorded, the video of compression and voice data are not decompressed.These data are transferred into hard disk drive 66 via bus 58, and blotter is on hard disk drive 66 then.When watching broadcasted content, these data are read from hard disk drive 66, decompress by AV decoder 54 then, thus the playback broadcasted content.
User interface control unit 56 is as carrying out the module that user's input operation is handled.User interface control unit 56 for example is provided with the key matrix (not shown), and it comprises action button/switch, is used for user's manual operation, and is provided with the function that receives the infrared remote control command.The user can utilize remote controllers to carry out the operation relevant with content via user interface control unit 56, for example selects the program of broadcast program, record, record programming, reproduction and deletion record.
Hard disk drive (HDD) 66 is used for predetermined file format stored program, data etc., and has big relatively capacity as external memory storage, for example tens arrives hundreds of GB.Hard disk drive 66 is connected to bus 58 via hard-disk interface 65.
Operating unit 67 has been configured to be attached to display device on the apparatus main body, LED, loud speaker etc.When via network when IP remote controllers 11 receive specified command (in the back describe), operating unit 67 is reacted and executable operations, for example show image such as icon or message, flash of light or the response by buzzer or voice message, make the user confirm that he or she has specified content providing device 50 thus.
Selectively, in response to the request from the IP remote controllers, controlled device can be carried out an operation, for example, replaces the display unit name information on its display that operates in of operating unit 67, such as user friendly default or user title is set.But, this have only when described controlled device be that television receiver or other are just feasible when having the device of display unit (describing in the back).Especially, when understandable user was provided with title and is used as name information, and such as the LED indication or produce the reacting phase ratio of buzzer, described operation was easier to the user and accepts.In addition, this has caused being easier to the system that the user understands.
In the network-based remote control system, a plurality of controlled devices can be controlled by the IP remote controllers.At this, as described with reference to figure 2, can suppose described a plurality of controlled device be present in user's visual range and scope outside.In this case, the user may want to specify and control the device that is positioned at its visual range.Under the situation in a plurality of similar devices are placed in user's visual range, the user may think only to specify and control one of these devices.But because the IP remote controllers are controlled at described device on the network as the control point, controller not only can typically be controlled the device in face of the user, but also can control other device.Therefore, when using the IP remote controllers, the controlled device in face of the user can not easily be specified in the visual observation mode.
In the tele-control system according to present embodiment, IP network is used to transmit from the order of IP remote controllers and the transmission response from controlled device.When controlled device is carried out an operation response,, also carry out an operation of depending on the equipment (that is, operating unit 67) that is attached on its main body except response transmission via IP network.For example, export, glisten or voice output by display device, LED or the loud speaker difference carries out image of appointed device.Thereby because the user can visually check this performed operation of equipment on the device main body that is attached to his or she in front, so he or she can determine whether the device of wishing is correctly specified.
A kind ofly be used to specify controlled device and confirm that the program of appointed controlled device is as follows: (1) IP remote controllers send an order that is used to specify controlled device via network to appointed device; (2) device that has received order sends a response via network to the IP remote controllers, and carry out an operation response, it depends on the equipment that is attached on the described device main body, for example show and represent that it is as the appointed icon of controlled device, flicker is attached to the LED on the panel of main body, produce buzzer, or the vibration main body; (3) user before the device surface detects this operation response.Otherwise, if the user not before device surface, he or she can not detect this operation response.The user can actually determine whether the device of wishing is correctly specified like this.
To be described a kind of being used in the program of specifying controlled device and the appointed controlled device of affirmation according to the tele-control system of present embodiment with reference to figure 5.
The controlled device A and the B that lay respectively at room 1 and 2 are connected to each other via network.In this case, the IP remote controllers can be specified controlled device A and B simultaneously via home network.
When the user who holds the IP remote controllers was positioned at room 1 and wants to specify controlled device A as controlled device, the order that is used to specify controlled device was sent to controlled device via network from the IP remote controllers.
Controlled device A sends a response to respond described order via network.In addition, controlled device A makes a response when utilizing operating unit 67 operations, thereby makes the user confirm that it is designated.More clearly, represent that designated icon or the message as controlled device of described device is displayed on the display or display unit on the panel that is attached to described device main body.Selectively, output buzzer or speech information.
When the order that is used to specify controlled device by mistakenly when the IP remote controllers are sent to controlled device B, controlled device B makes a response and operates (with top identical) simultaneously to respond described order.In this case, the user in the room 1 can not for example directly confirm the reaction of controlled device B in the visual observation mode.In addition, be positioned at identical room with the user and the user believes that he or she the controlled device A of appointment does not make a response.Therefore make the user notice that he or she specifies controlled device A failure, the user can specify controlled device A once more, makes the order that is used to specify controlled device can be sent to described device.
Fig. 6 shows the figure of the operating sequence of the controlled device of specifying controlled device and definite appointment.At this, suppose that controlled device A and B lay respectively in user's the visual range and outside the scope.In addition, suppose that also controlled device A and B meet UPnP (UPnP), the IP remote controllers are corresponding to the UPnP control point.UPnP is a kind of agreement, and it allows such as the interconnection each other of devices such as PC, ancillary equipment, AV device, phone and household electrical appliances, and the function of device separately is provided towards each other.
IP remote controllers 11 corresponding to the UPnP control point are connected to home network 10, and monitor that periodically multicast address/port is to monitor the connection status (S101) of each the UPnP device on the home network 10.
When the controlled device A that meets UPnP and B are connected to home network 10, DHCP of router one 3 (DHCP) and DNS (domain name system) server capability are operated, and make IP address and domain name be endowed each (S102 and the S202) among controlled device A and the B.
