Background
The network camera has an independent IP address and an embedded operating system so as to realize network video and monitoring, and can be directly connected to a network through a LAN, a DSL connection or a wireless network adapter. With the advent of the internet of things era, the application of the network camera is more and more extensive, but the application of the network camera in the market is not sufficient at present, namely, the network camera still stays on the traditional professional video monitoring or the monitoring in the consumer family field.
In addition, with the development of the times, as the smart televisions have networking capability and application program installation capability, more and more families choose to purchase the smart televisions, but most of the smart televisions have abundant computing resources which are not used. Moreover, the large screen of the smart television is very beneficial to displaying video data and some alarm information, such as initiating a home conference, someone pressing a doorbell, and the like.
As can be seen from the above, firstly, the rich resources of the smart television are not fully utilized, secondly, the developer of the smart television does not consider the requirement that the elderly parents want to actively communicate with the children's videos from the aspects of simplicity and applicability, and furthermore, many times, some sudden situations occur in the family, and the detection device may detect that abnormal state information is sent out at the same time, but the abnormal information is not obvious enough, so that the owner is likely to not find the abnormal state information.
If the intelligent television is sufficiently applied to the equipment which has pictures, impact force and networking function in life, many life requirements can be more convenient, and many emergency situations can be avoided. For example, a doorbell is pressed by a person, and when the owner is watching a television at home or is cleaning for hygiene, the owner is very likely to miss the doorbell sound. Also for example, older parents are less likely to use a cell phone because their cell phone screens are small and easily broken, making it difficult if a young person outside wants to initiate a video call to a parent at home, let alone the parent actively initiating a meeting request to his child. However, if the smart television and the network camera are combined together, the smart television and the network camera cannot be fully applied to our lives, and all people in the lives become more intelligent.

After the signal processing unit of the intelligent television is activated, the intelligent television is mutually triggered with at least one network camera through the network, that is, when the intelligent television processes a standby state, a dormant state and an in-use state, the network camera can trigger the intelligent television through the network and realize mutual communication, and the intelligent television can trigger the network camera through the network and realize mutual communication. Further, the signal processing unit of the intelligent television receives a request signal sent by a user or a controller, and sends the request signal to the display unit of the intelligent television. The display unit of the smart television can then give a prompt in the form of text and/or sound to the request signal on the screen of the smart television. The memory of such a system may be used to store various signals, instructions, and video streams. The memory can be a stand-alone memory or a cloud disk.
It should be noted that the above embodiment is only valid when the smart tv is in a standby, sleep or in use state.
As a preferred embodiment, the smart tv and the webcam can trigger each other on the network in the following way: when the network camera and the intelligent television are in the same local area network, the network camera and the intelligent television can mutually respond and discover each other in a broadcasting packet sending mode. When the network camera and the intelligent television are not in the same local area network, the network camera and the intelligent television can be connected with the cloud server, so that the cloud server can inform an application program on the intelligent television that the network camera and the intelligent television are in the same local area network, and then the application program actively initiates a request for connecting the network camera in the local area network, so that the other party is found. After the network camera and the intelligent television find each other, data communication can be carried out through the network. As another preferred embodiment, for a network camera having a serial port directly connected to the smart tv, the network camera may directly perform data communication and triggering through the serial port.
According to another embodiment of the present invention, the system includes the basic technical features of the above embodiment, and on the basis of the above embodiment, the system further includes that at least one smart device is directly or indirectly connected to the cloud server, the application program associates the corresponding smart device through the cloud server, when the smart device sends an instruction to the cloud server, the cloud server sends the corresponding instruction to the corresponding application program, and the corresponding application program displays corresponding information on the smart television. The intelligent device can include doorbell, intelligent lamp, smoke and feel etc. and can be connected to cloud server through the WIFI module of oneself or indirectly through repeater (HUB), and all information are preserved and are dispatched by cloud server. The smart device may also be a kit, such as a combination of a repeater, a doorbell, and a smoke sensation. Of course, other intelligent devices are also possible in the present embodiment. The combination of the intelligent devices and the intelligent television is mainly used for timely dealing with emergency situations in life, and the emergency situations discussed herein refer to a scene that a host is at home but some emergency situations occur but the host is not notified in time, for example, when people are at home, the host may be busy in housework, or may be watching television on the second floor, or due to other reasons, the host may not view the mobile phone in time. At this time, through the intelligent interconnection of the intelligent device, the intelligent television, the application program and the cloud server, as shown in fig. 2, the step of timely responding to the emergency may include: the method comprises the steps that a cloud server obtains information of intelligent hardware, wherein the intelligent hardware can be directly or indirectly connected to the cloud server through a network (intelligent equipment without network function can be indirectly connected through equipment with WIFI function such as a repeater); the intelligent television is provided with an application program corresponding to the intelligent equipment, the application program can find the intelligent equipment in the same local area network through a local area network discovery function, namely, a broadcast packet is sent on the network, and the application program can associate the intelligent equipment after the application program and the intelligent equipment respond to each other; when an emergency occurs, the intelligent device sends a request message to the cloud server, the cloud server sends the request message to an application program corresponding to the intelligent device on the intelligent television, and then the application program can jump out of a display window and display corresponding prompt information. For example, when the owner is watching television in a living room, if a guest visits and the doorbell owner is very likely not to hear, the intelligent doorbell can send a request to the cloud server, the cloud server sends the request message to an application program on the intelligent television of the user, the intelligent television can jump out of an information display window to prompt that the guest visits, and therefore the owner can effectively obtain information. For another example, if the owner is lying in a room for rest, soup in a pot in a kitchen is burnt out and smokes, the smoke alarm starts to give an alarm, and if information can be sent to the cloud server and the cloud server informs an application program on the smart television to turn on the television and play a designated alarm audio, the user can certainly detect and prevent danger from occurring.
According to another embodiment of the present invention, the system further comprises an application program, which configures the corresponding webcam to display the actual picture situation according to the user instruction. For example, on the basis of the above embodiment, a web camera installed in the field of view capable of detecting the smart device may be deployed by an application corresponding to the smart device to display the actual picture of the emergency. Specifically, for example, when a guest visits and presses a doorbell, the smart doorbell can send a request to the cloud server, and the cloud server sends the request message to an application program on the smart television of the user to turn on the smart television and can call a network camera near the door to display a doorbell picture on the smart television, so that the host can see the identity of the visitor, and a rogue can be prevented from entering a murder indoors.
As an alternative of the above embodiment of the present invention, the application program is configured to communicate with the cloud server at regular time, so that the cloud server updates and stores the application state of the application program and the external network address and the port information of the application program in time. Preferably, the time interval for the application to time the communication to the cloud server is set to 30 s.
According to another embodiment of the present invention, the system includes the basic technical features of the above embodiment, and on the basis of the above embodiment, the system further includes that the audio recognition device is directly or indirectly connected to the cloud server, and the application program or the cloud server parses the recognized audio file into a character string for the application program to send an instruction to the cloud server so as to start the corresponding program. The audio recognition device can be a separate device or a miniature microphone integrated with a network camera. In this case, the smart tv may be activated and/or a specific webcam invoked whenever the user calls a specific character + specific smart device against the audio recognition device. Specifically, when the user calls a particular character (which may be any kind of character), for example: when the user takes a doctor to see the kitchen, the audio recognition equipment can be switched to a working state after acquiring audio, and sends a subsequent key information kitchen audio file to an application program used for security monitoring on the smart television; the application program receives the audio file, analyzes the audio file and translates the audio file into character information, if the application program cannot successfully analyze the audio file, the application program directly sends the audio file to the cloud server, the cloud server analyzes the audio file, and after the cloud server successfully analyzes the audio file, the application program returns the character string information obtained by analysis to the application program; the application program requests the cloud server to call a corresponding network camera by acquiring the analyzed user requirement; and after receiving the request, the cloud server issues the request of the user to a corresponding application program on the smart television of the user and displays the prompt information and/or the video information.
According to another embodiment of the present invention, the system includes the basic technical features of the above embodiment, and on the basis of the above embodiment, the system can also establish a two-party video/conference call. If the user A and the user B can install the application programs for the videos on the respective smart televisions, the respective application programs are well paired with the network cameras, and the user A and the user B respectively perform account registration to the cloud server through the application programs to respectively obtain unique user names. When user a searches the application for user B's username, a video chat may be initiated to user B. As a preferred embodiment, after searching the user name of the user B in the application program, the user a may bind the relationship between the user a and the user B, and when the user a wants to initiate a video chat to the user B next time, the user a only needs to open the application program by using the television remote controller and select the user name of the user B to send a request for establishing the video chat with the user B to the cloud server, where a display screen of the smart television of the user a is shown in fig. 3 a. When the cloud server receives the video chat request and then sends the request to the application program on the smart television of the user B through the network, the smart television of the user B is activated and displays the prompt information no matter the smart television is in a use, sleep or standby state, and schematically, the display screen of the smart television of the user B is shown in fig. 3B. At the same time, the application of user B wakes up the webcam paired with the application. The user B can select to accept or reject the video request through the television remote controller, and the cloud server can send the acceptance or rejection signal to the application program of the user A. If the user B selects to receive the video request, after the application program of the user A receives an instruction sent by the cloud server, the network camera matched with the application program of the user A sends the acquired video stream to the cloud server and the acquired video stream is forwarded to the application program of the user B by the cloud server, and similarly, the network camera matched with the application program of the user B also sends the acquired video stream to the cloud server and the acquired video stream is forwarded to the application program of the user A by the cloud server. When any party user needs to hang up the video, the application program is controlled to be closed only through the television remote controller.
Further, the user A can call the specific character + the user name of the user B (for example, the user A takes a look at the son of the family) by facing the camera, and then the user A can directly call the smart television of the user B. Specifically, when user a calls a particular character (which may be any kind of character), for example: when the audio recognition device acquires audio, the audio recognition device can be switched to a working state, and sends a subsequent key information 'my family son' audio file to an application program for video call on the smart television; the method comprises the steps that after an audio file is received by a user, the user analyzes the audio file and translates the audio file into character information, if the application program cannot successfully analyze the audio file, the application program directly sends the audio file to a cloud server, the cloud server analyzes the audio file, and after the cloud server successfully analyzes the audio file, the application program returns character string information obtained through analysis to the application program; after the application program acquires the analyzed user name B, the application program requests a cloud server to initiate video call connection with the user name B; after receiving the request, the cloud server issues the request of the user A to a corresponding application program on the smart television of the user B and displays prompt information, and meanwhile, the application program can awaken the network camera of the user B; the user B can select to receive the video request through a remote controller or directly reply 'see-in-yourself' to the audio recognition device, the application program of the user B sends the confirmation information to the cloud server, and then the cloud server sends the confirmation information to the application program of the user A; after the application program of the user A receives the confirmation information sent by the cloud server and establishing connection with the user B, the network camera of the user A also transmits the acquired video stream to the cloud server and forwards the video stream to the user B, and meanwhile, the network camera of the user B also sends the acquired video stream to the cloud server and forwards the video stream of the user B to the user A, so that the user A and the user B can establish normal video call.
As a further improvement of the above embodiment, the video transmission of the two users may adopt a manner of saving the traffic of the cloud server, that is, the application program of the user a obtains the external network IP address and the port number of the application program of the user B through the cloud server, and meanwhile, the application program of the user B also obtains the external network IP address and the port number of the application program of the user a through the cloud server. Then, the user a and the user B can send data packets to the external network IP address and the port number of the other side, see whether the connection can be established, and if the connection can be successfully established, a direct video stream transmission channel can be established between the application programs without uploading and forwarding the video stream through the cloud server.
