Description

  The present invention relates to a transmission / reception system and a transmission / reception control method suitable for application to, for example, viewing content composed of video and audio, and in particular, receives a base device that relays content data and data from the base device. The present invention relates to a technique applied to a system including a receiving apparatus.

  Conventionally, when viewing content such as television broadcasting, it has been common to incorporate a tuner in a television receiver and display data received by the tuner on the receiver. For this reason, it is necessary to connect an antenna line to the television receiver, which limits the carrying of the receiver.

  As a television receiver that solves this problem, the present applicant has previously developed a transmission / reception system in which a base device incorporating a receiving means such as a tuner and a monitor device that displays video are separated. Patent Literature 1 describes a transmission / reception system including the base device and the monitor device.

In the case of this transmission / reception system, the standard of IEEE (The Institute of Electrical and Electronics Engineers) 802.11 which is a standard of a wireless local area network (LAN) is adopted between the base device and the monitor device. Thus, wireless communication is performed. Therefore, it is not necessary to connect a video signal source such as an antenna line or a video playback device to the monitor device, and the monitor device can be freely carried as long as it is within a range where communication with the base device is possible. Also, if the base device has a function of connecting to the Internet, contents such as video and audio downloaded via the Internet can be viewed on a portable monitor device. In the following description, video or audio content viewed on a monitor device is referred to as AV content regardless of whether it is received or reproduced in any form such as television broadcasting or the Internet.
JP 2002-33714 A

  By the way, in the case of the transmission / reception system described above, since data transmission between the base device and the monitor device is wireless, there is a merit that the monitor device can be carried freely, but it is wireless depending on the environment at that time and the distance between the two devices. The communication state may become unstable, and it cannot be said that AV contents can be viewed stably at all times.

  In order to solve this problem, for example, it is conceivable to connect the base device and the monitor device by wire and transmit the data of AV content by wire. If content data is transmitted, the configuration for wireless communication is wasted.

  In addition, even if a single system is configured to allow both wireless communication and wired communication, when actually transmitting AV content data between the base device and the monitor device, a mode is set by initial setting or the like. It is necessary to select the mode to transmit by wireless communication or the mode to transmit by wired communication. Once the mode is determined, the transmission state becomes unstable during communication. However, unless the initial setting menu is called and set again, it is impossible to change to another mode, and it is impossible to adaptively select two communication modes.

  The present invention has been made in view of the above points, and an object of the present invention is to enable transmission between two devices that transmit content data to make good use of prepared communication means to the maximum. And

  The present invention receives a predetermined content, receives the content transmitted from the base device via any of the networks, and a base device that transmits the received content via any of the plurality of networks, When performing transmission / reception control with a receiving device that displays received content, a detection process that detects network disconnection that is involved in content transmission is performed, and when network disconnection is detected in the detection process, the network In addition to displaying the disconnection of the network, a display for selecting a specific connectable network other than the one for which the disconnection is displayed is displayed, and the connection to the selected specific network is instructed based on the display. Network connection processing is performed.

  By doing this, when content is being transmitted on any network, when it becomes impossible to transmit on that network, a display for automatically connecting to another network is performed, By simply performing an operation based on the display, it is immediately connected to another network, and the content transmission is resumed.

  According to the present invention, when content cannot be transmitted on one of the networks during transmission, the display for automatically connecting to the other network is performed. By simply performing an operation based on the network, you can immediately connect to another network and resume the transmission of content, automatically without having to perform initial settings to select the network to use. Content can be transmitted over the network.

  In this case, the network disconnection detection process and the network connection instruction process are performed on the receiving apparatus side, and based on the network connection instruction process in the receiving apparatus, the connection process in the specific network instructed by the base apparatus is executed. By doing so, the network management can be satisfactorily performed on the base device side based on the detection and instruction of the actual reception state at the receiving device.

  In addition, as a connection process for a specific network on the base device side, authentication of the receiving device is performed, and connection processing is performed when it is determined that the instruction from the receiving device is registered in advance in the authentication processing. Thus, even when the network is switched, content is transmitted only to a device that has been properly authenticated, and malfunction can be effectively prevented.

  Further, since the plurality of networks are a wired LAN and a wireless LAN, it is possible to efficiently combine a wireless network and a wired network.

  In addition, by automatically selecting a specific network and instructing a connection without performing a display for selecting a connectable specific network other than the one where disconnection is displayed among a plurality of networks, user operation is completely performed. It becomes possible to cope with the network disconnection without performing.

Hereinafter, an embodiment of the present invention will be described with reference to FIGS.
FIG. 1 is a diagram showing a system configuration example of this example. In this example, the system is composed of a base device 200 that receives television broadcasts and downloads content via the Internet, and a monitor device 100 that is configured to be detachable from the base device 200. .

A USB terminal 249 and the like are provided.

  In the monitor device 100 and the base device 200 configured as described above, for example, the user fixedly installs the base device 200 in a place such as a living room, and carries the monitor device 100 in an arbitrary place such as a house or a garden. The AV device such as a television broadcast can be viewed by the monitor device 100 at hand in an arbitrary place. In addition, access to the Internet, transmission / reception of e-mail, and the like can be executed via the base device 200.

  In this case, the monitor device 100 can be used by holding it, but as shown in FIG. 5A, the stand 103 can be opened to allow the monitor device 100 to stand on a suitable surface.

  Further, as shown by a broken line in FIG. 5B, the monitor device 100 can be used by leaning against the front portion 210 of the base device 200. In this case, the charging terminal on the bottom surface of the monitor device 100 is in contact with the charging terminal on the base device 200 side (none of the charging terminals is shown), and the secondary battery in the monitor device 100 is replaced with the base device 200. It can be charged with a power source.

  Next, the functional block configuration of the monitor apparatus 100 of this example will be described with reference to FIG. The control unit 170 of the monitor device 100 includes a central control unit (CPU) 171 that is a control means, a ROM 172 in which a program to be executed by this device is written, and a RAM 173 that is used as a work area of the CPU 171. . A program for executing a communication network switching process, which will be described later, is also written in the ROM 172. A user memory 175 to which user data such as an image file is written is connected to the bus line 174, and a memory card 141 mounted in the slot 105 shown in FIG.

  In addition, a wireless LAN communication unit 182 and a wired LAN communication unit 184 are connected to the bus line 174 via the communication selection unit 181, and commands and various data to be transmitted to the base device 200 and the like are transmitted to the wireless LAN communication unit 182. Alternatively, transmission processing is performed by the wired LAN communication unit 184, and wireless transmission is performed from the antenna 183 at the time of wireless transmission, and transmission is performed by a cable connected to the LAN terminal 185 at the time of wired transmission. In addition, data received by the wireless LAN communication unit 182 or data received by the wired LAN communication unit 184 is sent to the bus line 174. Whether the wireless LAN communication unit 182 or the wired LAN communication unit 184 is used for communication is set by the communication selection unit 181 based on a command from the control unit 170.

  Further, the LCD 101 is connected to the bus line 174 through the display control unit 191, and speakers 107 and 108 are connected through the digital / analog converter 195 and the amplifier 196.

  Further, the touch panel 102 is connected to the bus line 174 via the coordinate detection unit 193, and the operation unit 109 is connected to the bus line 174 via the interface 199.

  Next, the functional block configuration of the base apparatus 200 of this example will be described with reference to FIG. The control unit 270 of the base device 200 includes a central control unit (CPU) 271 as control means, a ROM 272 in which a program to be executed by this device is written, and a RAM 273 used as a work area of the CPU 271 and the like. . A program for executing a communication network switching process, which will be described later, is also written in the ROM 272.

  A VHF / UHF antenna 1 is connected to the VHF / UHF terminal 239, which is a connection terminal of the antenna line, and the terrestrial television broadcast output received by the antenna 1 is the VHF / UHF in the base device 200. The channel is demodulated by the tuner 259, and video data and audio data are extracted and sent to the bus line 274.

  The telephone line 2 is connected to the line terminal 241 to which the line interface 261 is connected, and the line interface 261 is connected to the bus line 274 via the modem 262. It is possible to connect to the Internet or the like via the telephone line 2. Note that a terminal, an interface, and a modem that can be connected to other Internet connection lines such as ADSL (Asymmetric Digital Subscriber Line) instead of a telephone line may be prepared.

  For example, a digital CS broadcast tuner or a digital BS tuner is connected to the video / audio input terminal 246 as the first external device 6, and video data and audio data supplied from these devices are externally input in the base apparatus 200. The data is sent to the bus line 274 via the interface 266.

  For example, a DVD player or a hard disk recorder is connected to the video / audio input terminal 247 as the second external device 7, and video data and audio data supplied from these devices are input to the external input interface 267 in the base device 200. To the bus line 274.

  The terminals 243 and 244 are connected to AV mice 3 and 4 which are infrared signal light emitting devices. The terminals 243 and 244 are connected to the bus line 274 via the interfaces 263 and 264 in the base apparatus 200, and are transmitted as infrared signals transmitted from the light emitting units of the AV mice 3 and 4 by a command signal from the control unit 270. The remote control signal is received by the light receiving unit provided in the first external device 6 and the second external device 7, so that the first external device 6 and the second external device 7 can be remotely controlled on the base device 200 side. .

  For example, a printer 9 is connected to a USB (Universal Serial Bus) terminal 249, and printing commands and data sent to the bus line 274 are supplied to the printer 9 via the USB interface 269.

  In addition, a wireless LAN communication unit 282 and a wired LAN communication unit 283 are connected to the bus line 274 via a communication selection unit 281, and commands and various data to be transmitted to the monitor device 100 and the like are transmitted to the wireless LAN communication unit 282. Alternatively, transmission processing is performed by the wired LAN communication unit 283, and wireless transmission is performed from the antennas 207 and 208 during wireless transmission, and transmission through a cable connected to the LAN terminal 242 during wired transmission. In addition, data received by the wireless LAN communication unit 282 or data received by the wired LAN communication unit 283 is transmitted to the bus line 274. Whether the wireless LAN communication unit 282 or the wired LAN communication unit 283 is used for communication is set by the communication selection unit 281 based on a command from the control unit 270.

  Next, a processing example of this example when viewing AV content using the monitor device 100 and the base device 200 configured as described above will be described. First, bidirectional wireless communication is performed between the monitor device 100 and the base device 200 using the wireless LAN communication units 182 and 282, and AV content data is transferred from the base device 200 to the monitor device 100. It is assumed that the monitor device 100 is transmitting and transmitting. At this time, the control unit 170 of the monitor device 100 of the present example executes the processing shown in the flowchart of FIG. 8 as processing related to reception of content data. That is, it is determined whether or not the connection via the wireless LAN network has been disconnected for some reason while viewing the AV content (step S11). If there is no disconnection of the wireless LAN network, this determination is repeated. As long as the wireless LAN is not disconnected, AV content can be received by wireless transmission, and viewing on the monitor device 100 can be continued.

  When it is determined that a communication failure has occurred and the connection via the wireless LAN network is disconnected in step S11, it is determined whether there is a LAN cable connection to the terminal 185 (step S12). The determination of the connection of the LAN cable is determined from, for example, transmission or reception of some signal via the cable. Alternatively, the attachment of the plug to the terminal may be physically detected by some switch. Here, when the LAN cable is not connected, the AV content viewing stop processing is performed (step S19). Here, instead of the process of step S19, an implementation method of performing a process of trying to reconnect with a wireless LAN may be used.

  If it is determined in step S12 that a LAN cable is connected, a dialog box for changing to a wired LAN is displayed on the display screen configured by the LCD 101 of the monitor device 100 (step S13). For example, as shown in FIG. 10, the text “Wireless LAN has been disconnected. Do you want to connect via wired LAN?” And “OK” and “Cancel” buttons are displayed. The user can make any answer by touching the place where the button is displayed with, for example, the touch pen 10 shown in FIG.

  The control unit 170 waits until there is an answer to this dialog box (step S14). If there is an answer, the controller 170 determines whether there is an answer that accepts the network change (that is, when “OK” is pressed). (Step S15). If the answer does not agree with the change (that is, if “cancel” is pressed), the process proceeds to step S19 to perform a process of canceling viewing of the AV content. Here, instead of the process of step S19, an implementation method of performing a process of trying to reconnect with a wireless LAN may be used. If there is an answer to accept the change of the network, based on the control of the control unit 170, the communication selection unit 181 switches to communication using the wired LAN communication unit 184, and the wired LAN communication unit 184 is used. In this communication, authentication data is transmitted to the base device 200, and authentication processing for wired LAN connection is started (step S16). Thereafter, it is determined whether or not a notification of acceptance of authentication is transmitted from the base device 200 to the wired LAN communication unit 184 (step S17). When the notification of acceptance is transmitted, the wired LAN connection is completed. Then, the viewing of AV content data transmitted from the base device 200 is resumed by the wired LAN communication unit 184 (step S18). If the consent notification is not transmitted in step S17, the network connection by the wired LAN is not completed, and the process proceeds to step S19 to perform AV content viewing stop processing. Here, instead of the process of step S19, an implementation method of performing a process of trying to reconnect with a wireless LAN may be used.

  Next, an example of processing in the base apparatus 200 in a situation where AV content data is wirelessly transmitted from the base apparatus 200 side to the monitor apparatus 100 via the wireless LAN and viewed on the monitor apparatus 100 is shown in the flowchart of FIG. Will be described with reference to FIG. In a situation where the wireless LAN communication unit 282 of the base device 200 is transmitting content data, it is determined whether or not a LAN cable is connected to the terminal 242 (step S21). The determination of the connection of the LAN cable is determined from, for example, transmission or reception of some signal via the cable. Alternatively, the attachment of the plug to the terminal may be physically detected by some switch.

  Then, the wired LAN communication unit 283 determines whether there is an authentication request from the monitor device side via the wired LAN for which the connection is determined (step S22). If there is no authentication request, the process returns to the wired LAN connection determination in step S21. When there is an authentication request, the control unit 270 determines the received serial number of the monitor device, and determines whether or not it matches the serial number of the communication partner stored in the ROM 272 in the control unit 270 in advance ( Step S23). If the serial numbers do not match, the base apparatus 200 stops the process of transmitting the AV content to the monitor apparatus 100, and stops the AV content viewing process (step S26). Here, instead of the process of step S26, an implementation method of notifying the monitor with authentication NG and returning to S21 may be used.

  If the serial numbers match, the authentication process is completed, and the monitoring apparatus 100 is notified by the wired LAN communication that the authentication has been correctly performed (step S24). The AV content monitoring device is configured to switch the communication unit that completes the connection and transmits the AV content data from the wireless LAN communication unit 282 to the wired LAN communication unit 283 to start transmission via the wired LAN. Transmission to 100 is resumed (step S25).

  Next, bi-directional wired communication is performed between the monitor device 100 and the base device 200 using the respective wired LAN communication units 184 and 283, and AV content data is received from the base device 200 side. The process in the situation where the user is viewing the video on the monitor device 100 will be described. At this time, the control unit 170 of the monitor device 100 of the present example executes the processing shown in the flowchart of FIG. 11 as processing related to reception of content data. That is, it is determined whether or not the connection via the wired LAN network has been disconnected for some reason while viewing the AV content (step S31). If there is no disconnection of the wired LAN network, this determination is repeated. The disconnection of the wired LAN network is assumed to be, for example, that the cable is disconnected or the connection state is poor. As long as the wired LAN is not disconnected, AV content can be received by wired transmission, and viewing on the monitor device 100 can be continued.

  If any communication failure occurs, a dialog box for changing to a wireless LAN is displayed on the display screen constituted by the LCD 101 of the monitor device 100 (step S32). For example, as shown in FIG. 13, a message “Wired LAN has been disconnected. Do you want to connect via wireless LAN?” And “OK” and “Cancel” buttons are displayed. The user can make any answer by touching the place where the button is displayed with, for example, the touch pen 10 shown in FIG.

  The control unit 170 waits until there is an answer to this dialog box (step S33), and if there is an answer, determines whether there is an answer that accepts the change of the network (that is, when “OK” is pressed). (Step S34). If the answer does not agree with the change (that is, if “cancel” is pressed), the process proceeds to step S38, and AV content viewing stop processing is performed. Here, instead of the process of step S38, an implementation method of performing a process of trying to reconnect with a wired LAN may be used. When there is an answer to accept the change of the network, based on the control of the control unit 170, the communication selection unit 181 switches to communication using the wireless LAN communication unit 182 and wirelessly uses the wireless LAN communication unit 182. In this communication, authentication data is transmitted to the base device 200, and authentication processing for wireless LAN connection is started (step S35). Thereafter, it is determined whether or not a notification of acceptance of authentication is transmitted from the base device 200 to the wireless LAN communication unit 182 (step S36). When the notification of acceptance is transmitted, the wireless LAN connection is completed. As a result, viewing of AV content data transmitted from the base device 200 by the wireless LAN communication unit 182 is resumed (step S37). If the consent notification is not transmitted in step S36, the network connection by the wireless LAN is not completed, and the process proceeds to step S38 to perform AV content viewing stop processing. Here, instead of the process of step S38, an implementation method of performing a process of trying to reconnect with a wired LAN may be used.

  Next, a flowchart of FIG. 12 shows an example of processing in the base device 200 in a situation where AV content data is transmitted from the base device 200 side to the monitor device 100 via a wired LAN and viewed on the monitor device 100. Will be described with reference to FIG. While the content data is being transmitted by the wired LAN communication unit 283 of the base device 200, the wireless LAN communication unit 282 determines whether there is an authentication request from the monitor device side (step S41). Wait until there is. When there is an authentication request, the control unit 270 determines the received serial number of the monitor device, and determines whether or not it matches the serial number of the communication partner stored in the ROM 272 in the control unit 270 in advance ( Step S42). If the serial numbers do not match, the base apparatus 200 stops the process of transmitting the AV content to the monitor apparatus 100, and stops the AV content viewing process (step S45). Here, instead of the process of step S45, an implementation method of notifying the monitor with authentication NG and returning to S41 is also conceivable.

  If the serial numbers match, the authentication process is completed, and the monitoring apparatus 100 is notified of the successful authentication by wireless LAN communication (step S43). The AV content monitoring apparatus is configured to switch the communication unit that completes the connection and performs the AV content data transmission process from the wired LAN communication unit 283 to the wireless LAN communication unit 282 to start the wireless LAN transmission. Transmission to 100 is resumed (step S44).

  As described above, according to the system of this example, when there is a failure in the network that transmits the content data while viewing the AV content such as television broadcast on the monitor device 100, the system automatically transfers to another network. Since a connection inquiry is displayed on the screen and automatically connected to another network based on the result of the inquiry, the menu screen for initial setting etc. is displayed and connected as before. Transmission can be resumed quickly using a connectable network without changing the network one by one. Therefore, it becomes possible to easily cope with a transmission failure, and it is possible to seamlessly view AV content with minimal interruption.

  In the above-described embodiment, when the connected network is disconnected, a dialog box is displayed on the screen of the monitor device 100 indicating that the network is changed to another connectable specific network. I waited for an answer to change the network to that specific network, but when the network was disconnected, without selecting such a dialog box, I selected another specific network that I could connect to, and the selected network The connection process may be performed immediately.

  In the system configuration shown in FIG. 1, the monitor device 100 and the base device 200 communicate directly with each other over both wireless and wired LANs. May be performed.

  For example, as shown in FIG. 14, a router 98 that can be connected to the Internet 99 is prepared, and the router 98 and the LAN cable 91 are connected to the monitor device 100, and the router 98 and the LAN cable 92 are connected to the base device 200. As a configuration for this, communication via a wired LAN between the monitor device 100 and the base device 200 may be routed through the router 98.

  Further, in the case of the configuration shown in FIG. 14, for example, the monitor device 100 is directly connected to the Internet 99 (ie, not connected via the base device 200) by communication with the router 98 via a wired LAN to In a situation where downloading or the like is being performed, when a failure occurs in the cable 91 and communication between the monitor device 100 and the router 98 becomes impossible, processing similar to the above-described network switching is performed. The wireless LAN communication between the monitor device 100 and the base device 200 is performed to connect with the base device 200, and the base device 200 and the router 98 via the LAN cable 92 are communicated with each other. You may make it connect with the internet 99 via the apparatus 200. FIG.

  In the above-described embodiment, the present invention is applied to transmission between a monitor device for viewing AV content and a base device for transmitting content data to the monitor device. However, the system can be connected to other networks. The present invention is also applicable when transmitting content data or other various data.
