Description

  The present invention provides, for example, audio / video communication control for performing audio communication / video communication using a session initiation protocol (hereinafter referred to as SIP) for establishing / changing / ending a multimedia session on an IP network. The present invention relates to a device and a broadcast receiving terminal.

  Conventionally, in a system called telephone, which is a representative of voice communication, incoming calls are “a method that basically accepts all incoming calls (a method that permits by default).

  However, in recent years, the nuisance call has become a social problem, so the concept of incoming call restriction has been introduced, and it has become possible to reject incoming calls from callers who are on the “reject list” that they have set.

  On the other hand, with the widening of the backbone of communication systems and subscriber lines (suspensions), it is now possible to implement voice and video communication services using IP networks, so-called videophone services, with two-way communication technology. However, this kind of service is difficult to permeate because of the refusal to be seen by others.

  As a result of investigations, it has been found that the root of this feeling of refusal is a trap for sudden video communication in a communication system that can receive incoming calls from strangers.

  In order to alleviate this feeling of refusal, it is considered that the audio / video communication system provides videophone service by rejecting incoming calls by default and accepting only incoming calls from callers on the “permission list”. Yes.

  However, in this case, it is necessary to perform “registration of permitted parties” first, and it has become a very high threshold for users who are represented by the elderly, especially those who are not familiar with IT technology. .

  In order to make the threshold as low as possible, ask the other party to make a call to you once, and later on a specific party while looking at the list of callees (the list of all rejected callers in the first stage) There was also a method of moving to the permission list.

  However, even in this case, as compared with the conventional voice telephone, extra work is required before communication, and there are some which are not acceptable to general users.

  Further, in the conventional case, since the terminal of the caller is always rejected by the communication destination terminal when starting communication, the intention of the user who wants to use the videophone service has been killed.

As prior art for switching between video and audio, for example, there is already an answering videophone that can be set to only video or two of video and audio when setting an answering machine (see, for example, Patent Document 1).
JP-A-6-197338

  However, in the case of the above prior art, since it is possible to eliminate the voice for the purpose of monitoring when the user is away, the video display is essential. It is not suitable not to show the video of.

  The present invention has been made in order to solve such problems, and in providing a user with a voice / video communication service using an IP network, a voice / video that can improve user operability and convenience. An object is to provide a video communication control device and a broadcast receiving terminal.

  In order to solve the above-described problems, the audio / video communication control apparatus of the present invention is for enabling / rejecting an audio communication address list for each address and video communication for each address. A storage unit storing a video communication address list; a network interface for establishing voice communication and video communication on the IP network; and a network interface received from a terminal connected to the IP network. The address list of the storage unit is searched using the address information of the communication destination and the communication request source extracted from the call connection request message as a key, and it is determined whether or not to establish voice communication and / or video communication. The voice communication is established by the determination unit and the determination unit. A voice communication controller that establishes voice communication between the permitted communication request source terminal and the communication destination terminal; and after the voice communication between the terminals is established, video communication is performed from the communication destination terminal. And a video communication controller that establishes video communication between the terminals when a response message indicating permission is received.

  The broadcast receiving terminal of the present invention includes a tuner that receives a broadcast of a selected channel, a video display that displays a screen of the broadcast of the channel received by the tuner, and a speaker that outputs audio of the broadcast of the channel. A video camera, a network interface for establishing a multimedia session on the IP network, and audio / video communication control for session initiation protocol communication from a communication request source terminal connected to the IP network When a call connection request message via a device is received by the network interface, an incoming call is notified from the video display and / or the speaker, and an instruction operation for permitting voice communication is performed in response to the notification. If performed, voice communication with the communication request source terminal After that, when an instruction operation for permitting video communication is performed, video communication between the terminals is established and video captured by the camera is transmitted while received from the terminal requesting communication And a control unit for displaying the recorded video on the screen of the video display.

  In the present invention, when there is a call connection request from the communication request source terminal to the communication destination terminal, voice communication is established prior to video communication (including audio unless otherwise specified), and the communication destination user is established. To hear the voice of the other party requesting the communication. If it is considered that the user of the communication destination can permit video communication for the other party, a simple permission operation such as a mouse operation or a button selection operation on the remote control can be performed on the communication destination terminal. By automatically establishing communication and registering in the permission list for video communication, the communication partner can then perform visual communication of audio and video without having to perform registration operations on the permission list. As a result, it is possible to improve user convenience and promote service subscription.

  The control unit 261 uses the server device discovery function 261d to discover UPnP compatible devices on the network using the UPnP discovery function. For example, the server device discovery function 261d discovers the content server 128 using the UPnP discovery function.

  The control unit 261 controls the UPnP compatible device using the UPnP control function by the content information acquisition function 261e, and acquires URI information necessary for accessing the content in the UPnP compatible device. For example, the content information acquisition function 261 e controls the content server 128 and acquires from the content server 128 URI information necessary for accessing content stored in an HDD or the like in the content server 128.

  The control unit 261 uses the content access control function 261f to obtain the IP address information of the server device acquired by the server device discovery function 261d, the IP address information obtained from the URI information acquired by the content information acquisition function 261e, and the digital television 111. Based on the IP address and netmask assigned to the LAN terminal 122, it is determined whether to access the content. If the control unit 261 determines that access is permitted, the control unit 261 allows the content access to be permitted.

  In addition, when the communication I / F 270 receives a call connection request message via the SIP server 170 from the communication source terminal 160 connected to the network 132, the control unit 261 calls the screen of the video display 114. To pop up the screen 190 (FIG. 7) and display a message such as “Call me from ...” to notify an incoming call, and the call button 191 or the like is pressed in response to this notification to allow voice communication When the instruction operation is performed, a response message to that effect is returned to the SIP server 170.

  The notification of the incoming call may be made not only by the video display 114 but also from the speaker 115 to notify the incoming call, and the incoming call may be notified by at least one of these notification means.

  In addition, when the voice communication with the communication source terminal 160 is established by replying the response message, the control unit 261 determines whether video communication is possible by blinking the video button 192 on the telephone screen 190 of the video display 114. When an instruction operation for permitting video communication is performed by, for example, pressing the video button 192 in response to the information prompting the instruction operation, a response message to that effect is sent to the SIP server 170. In response, the video communication between the terminals is established and the video captured by the video camera 150 is transmitted, while the video received from the communication source terminal 160 is displayed on the screen of the video display 114.

  After the instruction operation for permitting video communication is performed, the control unit 261 receives the video 197 received from the communication source terminal 160 via the SIP server 170 and being received by the tuner 245a or the tuner 250a. The picture is displayed on the screen 114a of the display 114 in the form of picture-in-picture (PinP) (see FIG. 8).

  When the call connection request message is received, the control unit 261 notifies the incoming call by popping up the telephone screen 190 on the screen 114a of the video display 114 receiving the broadcast by the tuner 245a.

  Hereinafter, the configuration in the signal processing unit 247 will be described in detail with reference to FIG. In FIG. 2, there are two systems of digital broadcast reception signal inputs, but these signal processing blocks are not shown in FIG. In FIG. 3, only the block for reproducing the content input in the form of a transport stream reproduced from the content server 128 is described.

  In the case of performing bidirectional video communication, a video camera (video camera 150 or video camera 152) is connected to the digital television 111. The video camera is i. In the case of a digital video camera having a LINK interface, i. Connect to the LINK terminal. Also, the video camera is i. If the camera does not have a LINK interface, connect the video camera to the analog AV terminal. i. The video / audio signal input by LINK has already been encoded.

  When the video camera 150 is connected to the analog AV terminal, the analog video signal and audio signal input from the video camera 150 are encoded by the encoder 151 including an AD conversion function. Communication is established via a SIP message exchange between each terminal and the SIP server 170 by connecting to the SIP server 170 on the network 132 via a router and a network connected via the communication terminal 122.

  When a call connection request message is transmitted from the communication source terminal 160 to the communication partner terminal, for example, the digital television 111, and a connection permission message is received from the relaying SIP server 170 in response to the call connection request message, A direct link is established (a session is established) between the communication source terminal 160 and the digital television 111, that is, between the terminals, and communication is performed. In this communication, first, the capability exchange is performed to adjust the video / audio encoding parameters and the like, and then the encoded video / audio signals are exchanged to realize bidirectional communication.

  As shown in FIG. 3, the SIP server 170 includes a network interface 171 (hereinafter referred to as NET I / F 171), a determination unit 172, an audio communication controller 173, a video communication controller 174, a registration unit 175, and a storage unit 180. These controllers and units realize a call connection restriction function.

  The storage unit 180 stores a voice communication address list 181 for permitting or rejecting voice communication for each address and a video communication address list 184 for permitting or rejecting video communication for each address. Yes.

  The address list 181 for video communication and the address list 184 for audio communication are respectively permitted lists 183 and 186 in which URIs, which are address information permitted to communicate at least once, are registered, and each communication is rejected at least once. It consists of rejection lists 182 and 185 in which URIs are registered.

  As shown in FIG. 4, the rejection list 182 stores URIs of communication sources that are rejected for each communication destination. In this example, for the communication destination URI “SIP: XXX@XXX.com”, as rejected URIs, “SIP: ΔΔΔ@ZZZ.co.jp”, “SIP: ΔX □ @ XYZ .Co.jp "and" SIP: ΔXXΔ@ZZX.com "are already registered.

  As shown in FIG. 5, the permission list 186 stores URIs that are permitted for each communication destination. In this example, the URI of the permitted communication source is not yet registered for the URI “SIP: XXX@XXX.com” of the communication destination.

  The NET I / F 171 is an interface for connecting the server to the network 132 and establishing voice communication and video communication on the network 132.

  The determination unit 172 stores, as a key, the URI of the digital television 111 and the communication source terminal 160 extracted from the call connection request message received by the NET I / F 171 from the terminal connected to the network 132, for example, the communication source terminal 160. The address lists 181 and 184 of the unit 180 are searched, and whether or not to establish voice communication and / or video communication is determined depending on whether or not the corresponding URI is registered.

  That is, the determination unit 172 searches the address lists 181 and 184 using the communication destination and the URI of the communication source included in the call connection request received from the communication source terminal 160 as keys, and determines whether or not the voice communication is permitted. To do.

  For the URIs (addresses of the communication source terminal 160) that do not exist in the address lists 181 and 184, the determination unit 172 determines that voice communication is “permitted” and video communication is “rejected” by default setting.

  The voice communication controller 173 transmits a call connection request message to the digital television 111 from the communication source terminal 160 permitted to establish voice communication by the determination unit 172 to the digital television 111.

  The voice communication controller 173 establishes voice communication between the terminals when a response message for permitting a call is received from the digital television 111 in response to the call connection request message.

  The video communication controller 174 establishes video communication between the terminals when a response message indicating that video communication is permitted is received from the digital television 111 after the voice communication controller 173 has established voice communication between the terminals.

  The registration unit 175 receives the response message indicating that video communication is permitted from the digital television 111 when the video button 192 of the digital television 111 is pressed or the permission registration button 194 is pressed. The URI of the terminal 160 is registered in the video communication permission list 186 as a URI that permits video communication.

  The operation of this audio / video communication system will be described below with reference to FIGS.

  In the case of this audio / video communication system, the user of the communication source terminal 160 who wants to start a videophone (communication) with the user of the digital TV 111 activates the videophone function of the communication source terminal 160 to A call connection request message is transmitted to the SIP server 170 by performing a call operation after designating the URI of the digital television 111 from the screen (S101). The call connection request message includes at least the URI of the communication source terminal 160 and the URI of the transmission destination. In this example, for example, the URI of the communication source terminal 160 is “SIP: □□@XX.com”, and the URI of the transmission destination digital television 111 is “SIP: XXXXX.com”. .

  In the SIP server 170, when the call connection request message is received by the NET I / F 171 (S102), the determination unit 172 extracts the communication destination URI and the communication source URI from the call connection request message. In this example, the communication source is the communication source terminal 160 and the communication destination is the digital television 111.

  The determination unit 172 first checks the connection restriction mode of the digital television 111 that is the destination terminal. In this example, in the initial state, the video communication profile of the digital television 111 is in the “default rejection” mode, and the permission list 186 is empty. It is assumed that the voice communication profile is “default permission”.

  Therefore, the determination unit 172 searches the rejection list 182 of the address list 181 for voice communication in the storage unit 180 using the extracted URIs of the digital television 111 and the communication source terminal 160 as keys, and the URI corresponding to the rejection list 182 is found. Whether or not connection is possible is confirmed based on whether or not it exists (whether or not there is a URI) (S103). For example, if the URI of the communication source terminal 160 is registered in the voice communication rejection list 182 by the search, the incoming voice communication is rejected.

  As a result of the search, if the URI of the communication source terminal 160 is not registered in the voice communication rejection list 182, the determination unit 172 determines that the voice call connection is permitted because the connection restriction mode is “default permission”. The determination is made (S104), and a permission signal is sent to the voice communication controller 173.

  Upon receiving the permission signal, the voice communication controller 173 transfers a voice call connection request message to the digital television 111.

  In the digital television 111, when a voice call connection request message is received while the user is watching a television broadcast, the control unit 261 displays a telephone screen 190 on the screen 114a of the video display 114 as shown in FIG. Is displayed, the incoming call is notified (S104).

  On the telephone screen 190, a message such as “Call from XXX@XXX.com” and operations such as a call button 191, a video button 192, an end button 193, a permission registration button 194, a rejection registration button 195, etc. The button is displayed. In addition, video communication buttons and the like are also prepared as operation buttons.

  In this example, the URI is displayed as a message as it is, but the name of the communication source user may be included in the display message by storing a correspondence table between the URI and the name in the nonvolatile memory 261c.

  When the user who is watching the TV call who has confirmed the incoming call on the hop-up displayed telephone screen 190 presses the call button 191 by operating the remote controller 117 or the mouse (S105), the control unit 261 causes the voice call connection. In response to the request message, a response message for permitting a call is transmitted to the communication source terminal 160 via the SIP server 170.

  As a result, a voice communication session is established between the communication source terminal 160 and the digital television 111 (S107), and voice communication is enabled between them (S108).

  After the voice communication is established, the control unit 261 prompts the user to perform an instruction operation on whether or not the video communication is possible by, for example, blinking the video button 192 on the telephone screen 190 or the video communication button for now (S109). Output information.

  On the other hand, when the user who has heard the voice of the call partner confirms the other party of the communication source terminal 160 and presses the video button 192 or the video communication button only now (S110), the control unit 261 permits video communication. Assuming that an instruction operation for performing this is performed, a message (video communication connection request message) to permit video communication is transmitted to the SIP server 170.

  When receiving the video communication connection request message, the SIP server 170 transfers the message to the communication source terminal 160.

  As a result, a video communication session is established between the communication source terminal 160 and the digital television 111 (S111), and video and audio can be simultaneously communicated with each other. The control unit 261 is photographed by the video camera 150. On the other hand, as shown in FIG. 8, the other party's video 197 received from the communication source terminal 160 is displayed on the screen 114a of the video display 114 (S112).

  During a videophone call, the user on the digital television 111 operates the permission registration button 194, so that a registration request message is transmitted to the SIP server 170 by the control unit 261.

  In the SIP server 170, the registration unit 175 registers the address information of the communication partner in the permission lists 183 and 186 (S113).

  Also, when the user on the digital TV 111 side presses the end call button 193 in order to end the videophone call (S114), if video communication is permitted during the call, registration is performed in the same manner as the permission registration button 194. Since the request message is transmitted to the SIP server 170, the information of the communication partner can be registered in the permission lists 183 and 186 without performing a registration operation (S115).

  In other words, the user on the digital television 111 side can perform one-touch registration for permitting the other party to communicate with voice and video from the next time during or during a voice call.

  Note that a registration button (not shown) for “registering the last person in the permission list” provided on the telephone screen 190 of the digital television 111 even when video communication is not performed during a voice call. , The control unit 261 sends a message requesting registration to the voice call permission list to the SIP server 170, triggered by the end of the voice call, that is, the pressing operation of the call end button 193. Therefore, in the SIP server 170, the registration unit 175 registers the URI of the communication partner in the permission list 183, and the address list 181 is updated.

  That is, registration to the permission list 183 for voice communication can be performed by one-touch operation of the call end button 193.

  As described above, according to the audio / video communication system of this embodiment, when the voice communication and video communication modes are set in the initial setting, the other party to be called is not registered in the address lists 181 and 184. Even so, a voice call can be made.

  In addition, when an incoming call is received while watching a TV broadcast, the telephone screen 190 is displayed on the screen 114a of the video display 114, and a call can be made by pressing the call button 191 once. The video button is displayed on the telephone screen 190 during the call. Video communication becomes possible with a single operation of 192. By pressing the end call button 193, the information of the communication partner is automatically registered in the permission list at the same time as the videophone call is terminated. A user who is unfamiliar with the registration mechanism can use the videophone service to confirm the other party with voice and then shift to video communication. Moreover, the other party can be naturally registered in the permission list from the next time.

  As a result, it is possible to improve the convenience of the user in providing the videophone service using the IP network to the user and promote the subscription to this service.
