FIG. 6A shows a schematic diagram of a structure and a user interface for data transmission of a smart TV according to an embodiment of the present application.

In some embodiments, the smart TV may include multiple network cable interfaces, and each network cable interface corresponds to a corresponding Ethernet card configured on the smart TV, so that the smart TV can access different wired network links.

For example, the TV can be equipped with two network cable interfaces, and the first network cable interface and the second network cable interface can be set at the bottom of the local TV; of course, the smart TV schematic diagram shown in Figure 6A does not limit the above-mentioned network cable interface. position, the first network cable interface and the second network cable interface can also be set on the same side, upper part, or back of the TV casing at the same time;

It should be noted that when the first or second network cable interface is plugged into an available wired network, it means that the first network card corresponding to the first network cable interface is connected to the network, or the second network card corresponding to the second network cable interface is connected to the network. For the wired network, for ease of understanding, the network cable interface corresponding to the network card in FIG. 6A is marked as a network card for ease of description, and will not be described in detail below.

The smart TV display can display a user interface, and the user interface can display the live channel of the smart TV, or run and display the installed application content. Different video applications, etc. It should be noted that when the user starts a specific desktop application, and both the above-mentioned first network card and the second network card are plugged into the available wired network, the controller of the smart TV can control the specific application program while using the above-mentioned two wired networks to transmit the specific application The communication data of the program, in order to break through the bandwidth and speed limit when using a single network to transmit data.

For example, when the smart TV user interface runs the camera fusion display application, the controller can control the application to simultaneously transmit data through the first network link corresponding to the first network card and the second network link corresponding to the second network card, and take over.

It can be understood that, assuming that the camera fusion display application uses only the first network link corresponding to the first network card to transmit data, since the bandwidth of the first network link is low, the peer device receives the data sent by the current smart TV, And when it is displayed on its user interface, its playback screen will be stuck or there will be a phenomenon of blurred screen, which is caused by the network transmission speed cannot meet the playback;

However, when the display device provided by this application realizes the above-mentioned data transmission and display, the two network cards of the two TVs are respectively connected to two wired network links with the same bandwidth, and the data of the current display device passes through the above two network links at the same time. If the network link is used for transmission, its transmission bandwidth will also become twice that of a single-line network, and the amount of data received by the corresponding peer device per unit time will also become twice that of a single-line network, which will satisfy the requirements to a certain extent. The data volume requirements of the playback screen of the terminal device can be adjusted to avoid the occurrence of freezes and blurred screens.

It should be noted that the smart TV can also be configured with a wireless network card for accessing the network. When the wireless network environment where the smart TV is located is available, the controller can also control specific applications in the above-mentioned desktop applications through the wired network and the wireless network at the same time. Wireless network for communication; Smart TV can also be configured with a virtual network card for transferring data, the virtual network card can receive data from the application and forward it to different network cards of the TV for network transmission, or receive data transmitted by multiple TV network cards and Feed it back to a specific application.

It should be noted that the different network links described in this application may include different local area networks, private line networks, and service networks; in some embodiments, the network links described in this application may also include physical access lines, For example, the room is connected to the same gateway, network ports or network interfaces in different locations.

It can be understood that the smart TV provided by this application can realize the access scenario of simultaneously accessing two wired network links, or simultaneously accessing one wired network link and one wireless network link, and performing network communication at the same time.

FIG. 6B shows a schematic diagram of the structure and user interface of smart TV data transmission according to another embodiment of the present application.

In some embodiments, the smart TVs provided in this application can be networked with each other, so as to realize the speed-up effect of the dual-link network between devices provided in this application.

For example, if there are 2 smart TVs in the family to be used for data transmission, each smart TV can be configured with 2 wired network cards; end device.

In some embodiments, the display device is configured with a first network card and a second network card, and the peer device is configured with a third network card and a fourth network card, and the available network in the environment includes the first network link and the second network link that are wired. Two network links;

Firstly, control the display device to connect the display device to the first network link through the first network card, and connect to the second network link through the second network card; then control the peer device to connect to the first network link through the third network card, The fourth network card is connected to the second network link; finally, two communicable network links can be established between the display device and the peer device, and the display device can send data to the third network link through the first network link corresponding to the first network card. The peer device where the network card is located can also simultaneously send data to the peer device where the fourth network card is located through the second network link corresponding to the second network card, and dual-link data transmission between devices can be established.

In some embodiments, when the display device controller receives a signaling to display the running application content of the user interface on the peer device, the controller will start the data transmission mechanism.

For example, when the display device runs the camera fusion display application, its user interface displays and plays the video content captured by the camera of the current display device; The camera of the device collects video images, and the images collected by the camera are only displayed and played on the current display device. The user interface and network architecture between devices are shown in Figure 6B.

In some embodiments, based on the user interface described in FIG. 6B, if the user activates the screen projection button, the smart TV controller will receive a signaling to display the content of the application running on the user interface on the peer device, and the controller will start the projection. The screen mechanism, that is, the data transmission mechanism, after the screen projection is completed, the user interface of the peer device is shown in Figure 6C.

First, the controller sends the data to be transmitted from the camera fusion display application to the established virtual network card, the data to be transmitted may also be called the first application content data, and the camera fusion display application content displayed on the user interface is also may be referred to as the first application content;

Then, after the data to be transmitted by the camera fusion display application produced by the display device passes through the virtual network card, the controller controller splits the above data, for example, into the first data set and the second data set; it can be understood that the data to be transmitted It needs to be transmitted to the peer device through two different network links. After splitting, it can be transmitted simultaneously from different network links respectively. The specific data splitting method is not specifically limited in this application.

Then, the smart TV controller controls the split first data set to send data through the first network card, sends the first data set to the third network card corresponding to the peer device through the first network link, and sends the The second data set is sent to the fourth network card corresponding to the peer device through the second network link, and its logical diagram is shown in Figure 8;

Finally, under the control of the controller of the peer device, the first data set and the second data set transmitted to the peer device are integrated again to complete the display and play on the user interface of the peer device, realizing the display device The camera fusion display application content is displayed on the peer device user interface through dual network links, and the content displayed on the peer device is the same as the current display device display content. Both are camera fusion display application content, and its user interface and The networking architecture between devices is shown in FIG. 6C .

In some embodiments, the smart TV controller splits the first application content data into the first data set and the second data set, which can be specifically implemented through the following solutions.

Firstly, the smart TV controller obtains the first application content data packet corresponding to the first application content data transmitted through the virtual network card. The first application content data packet is sent by the sending end application of the display device and transmitted to the virtual network card.

Then, the controller splits the obtained first application content data packet into a first data set containing odd data and a second data set containing even data packets;

Take the network ping command to capture data packets as an example. The data packet format is based on ICMP (Internet Control Message Protocol), and its format fields include source address, destination address, sequence number, data, etc.; since the Android kernel is linux, its The sequence number is in big-endian format, as shown in the schematic diagram of the data message format in Figure 7;

The smart TV controller can also create a data processing service, and the service can obtain the data packet transmitted by the above-mentioned virtual network card through read (reading mode), and then read its sequence number, for example, the read content is 0X0001, 0X0002, 0x0003, etc., Divide into two groups of data packets according to odd numbers and even numbers, and finally the controller extracts the data packets whose message sequence number is odd in the first application content data packet to generate the first data set, and simultaneously extracts the message sequence number in the first application content data packet A second data set is generated for even-numbered data packets, as shown in FIG. 8 .

In some embodiments, in order to perform data splitting or data integration, the smart TV controller also creates a data processing service for data interaction with the virtual network card in the TV system.

For example, when the display device sends data, the data packets it needs to transmit to the peer device go through the network protocol stack and reach the virtual network card. The service data service created above will read the network data of the virtual network card node, and then The sequence number splits the data packets into odd packets and even packets, and then transmits them to the first network card of the display device configuration through the system socket (interface), and the second network card to the network card, such as sending odd packets to the first network card, sending The even-numbered packets are sent to the second network card for transmission.

It can be understood that when the smart TV sends data, its data processing service splits the first application content data transmitted through the network protocol stack and the virtual network card into the first data set and the second data set; similarly, when the smart TV receives data Its data processing service writes the data received by the first network card and the second network card into the virtual network card after removing the packet header, so that the data received by the corresponding specific application can be displayed and played.

FIG. 6D shows a schematic diagram of the structure and user interface of smart TV data transmission according to another embodiment of the present application.

In some embodiments, the smart TVs that need to transmit data can also be configured to perform data transmission through wired network links and wireless network links at the same time.

For example, the display device is configured with a first network card, and its second network card can be implemented as a wireless network card; the peer device is configured with a third network card, and its fourth network card can be implemented as a wireless network card; available networks in the environment include wired first A wired network link, and an available second network link, may be implemented as a corresponding second wireless network link.

First, control the display device to access the first wired network link through the first network card, and access the second wireless network link through its wireless network card; then control the peer device to access the first wired network link through the third network card, and Its wireless network card is connected to the corresponding second wireless network link; then finally, two communicable network links can be established between the display device and the peer device, and the display device can send data through the first wired network link corresponding to the first network card. The data is sent to the peer device where the third network card is located, and the data can also be sent to the wireless network card of the peer device through the second wireless network link corresponding to the wireless network card of the display device at the same time, so that dual-link data transmission between devices can be established.

It can be understood that, in some embodiments, for a smart TV configured with two wired network cards and one wireless network card, usually two wired network cards can be selected for networking configuration, and a combination of wired network cards and wireless network cards can also be selected for networking Configure to establish dual links.

FIG. 6E shows a schematic diagram of the structure and user interface of smart TV data transmission according to another embodiment of the present application.

In some embodiments, the current display device can also be configured to receive a screen projection display request from the peer device, the first network link of which can be implemented as a wired network link, and the second network link can be implemented as a wireless network link road.

For example, the smart TV receives the second signaling sent by the peer device, and the second signaling is used to display the first video application content being displayed and played by the peer device on the user interface of the current display device.

When the controller receives the projection signal, it will control the data packets sent by the peer device to the first network card and wireless network card of the display device to integrate; as mentioned above, the data packets received by the network card of the display device can be implemented as The above-mentioned odd-numbered packets and even-numbered packets, the controller controls the received data to be integrated and then sent to the established virtual network card, and then uniformly sent to the first video application corresponding to the display device, so that the user interface of the display device displays that the peer device is The first app content to play. For example, the received odd-numbered packets and even-numbered packets arrive at the first network card and the second network card respectively, and then the created data processing service monitors the read network data packets, and removes the read data from the first network card and the second network card The IP header is written into the created virtual network card and sent to the network protocol stack to reach the target application. The logic diagram is shown in Figure 9.

It should be noted that, in some embodiments, when the display device receives and displays the projected screen content, it can also be configured to use some common applications for playback and display, and is not limited to use the same application program as the peer device.

It can be understood that when the display device receives data, similar to the data sent by it, the application content data generated by the peer device also needs to be split and transmitted to the current display device through the first network link and the second network link respectively.

In some embodiments, the first wired network card and the second network card of the smart TV may also be implemented as different links for accessing the same local area network.

For example, the living room is provided with four network ports for accessing the same network, network port 1, network port 2, network port 3, and network port 4; the first network card of the display device is connected to network port 1, and the second network card is connected to the network port port 2; the third network card of the peer device is connected to network port 3, and the fourth network card is connected to network port 4; then in the same LAN, the controller establishes the first network link based on the IP addresses of the first network card and the third network card At the same time, a second network link is established based on the IP addresses of the second network card and the fourth network card, so as to realize simultaneous data transmission between devices through multiple network links. The network architecture is shown in Figure 6F.

It can be understood that when the bandwidth support capability of the TV network card is low and the bandwidth of the local area network is high, such a networking method between devices can break through the bottleneck limit of transmission bandwidth; and the quality of the optical cables and coaxial cables used in the first network link In scenarios where flaws affect the transmission bandwidth and speed, such a networking method between devices can also break through the bottleneck limitation of transmission bandwidth and speed, and will produce different network experiences for users.

Therefore, the above-mentioned technical solution enables the TV to break through the current technical bottleneck, and can use multiple network access at the same time, for example, it can simultaneously access a wired network, a WIFI network, or simultaneously access two broadband networks existing in the home environment, or Access from different network entrances of the same network to avoid insufficient network bandwidth caused by multiple applications using the network at the same time, or network bandwidth degradation caused by the quality of specific network entrance lines.

It can be understood that multiple network cards of the display device in this application can be connected to multiple networks, and can also be used to transmit data through multiple physical links in the same local area network, so as to avoid link network bandwidth degradation caused by poor quality of some network lines in the home problems, and ensure that the network links used by important applications are in good condition.

It should be noted that when the user starts a different desktop application, and the above-mentioned first network cable interface and the second network cable interface are both plugged into a network cable that can be connected to the network, the controller of the smart TV can control the specific application program to use the specific network cable interface. Network card for network communication.

For example, when the smart TV user interface runs a video intercom doorbell, the controller can control the video intercom doorbell application to obtain network data through the first network card corresponding to the first network cable interface; The second network card corresponding to the second network cable interface acquires network data.

It should be noted that the smart TV can also be configured with a wireless network card.

In some embodiments, when the user turns on the smart TV, the controller of the smart TV will receive a signal input by the user to start the smart TV at this moment, for example, a power-on signal sent by a remote control.

After the TV is started, in addition to the automatic start of the regular services of the Android framework, the smart TV controller also creates the first service in the system. When the network cable or wireless network card scans for an accessible wireless network, the first service can identify the wireless network card that can currently obtain the network connection and the wired network card corresponding to the network cable interface.

Among them, the smart TV defines one of the wired network cards as the first wired network card, and the first wired network card can be configured to be used for accessing a dedicated network, video intercom doorbell application, and community video outpatient clinic.

Specifically, it may be implemented as an IP address.

For example, the video intercom doorbell application running on the user interface, the application must communicate through the community private network before it can run;

The first network cable interface corresponding to the first wired network card of the TV is connected to the network through the first network link and the community private network. When the first service created by the controller recognizes that the first wired network card is connected to the network, it will obtain an access IP address of the first wired NIC connected to the private network.

After the first wired network card is successfully connected to the network, the video intercom doorbell can operate normally. When the guest rings the doorbell outside the door, the monitoring screen of the doorbell will be transmitted to the first wired network card of the smart TV through a dedicated network. After the data is processed, it is displayed on the video intercom doorbell application interface. Since the doorbell application performs network communication through a dedicated network and a dedicated network card, it does not have an impact on network bandwidth occupation of other video playback applications or live channels on the user interface of the smart TV.

The controller first controls the first service to query whether the network node of the first wired network card exists, and if it exists, it means that the network node is ready; the controller will control the first service to start the first wired network card; The IP address of the first wired network card, and then the server receives the request to obtain the IP message sent by the client through the dynamic host configuration protocol, and writes the IP address information of the first wired network card into the first wired network card, and the first wired network card will write it to the first wired network card. The IP address information is sent to the kernel for calling by the Android framework service to access the network.

In some embodiments, the smart TV is configured such that its normal application program accesses the network through the second network link corresponding to the second network card to communicate.

For example, when the second network card is implemented as a second wired network card, the first video application can communicate and run on the user interface through the second network link at this moment, and the first video application communicates through the second network card;

It can be understood that the second network card can also be implemented as a second wireless network card, that is, when the smart TV is connected to the wireless network through the wireless network card, the first video application communicates through the second network card;

It should be noted that, in some embodiments, common applications in smart TVs that do not depend on dedicated networks are often configured to communicate through a wireless network or a wired network accessed by the second network card. May include first, second, third video applications, and weather forecast applications.

It can be understood that, in some embodiments, for a smart TV configured with 2 wired network cards and 1 wireless network card, usually one of the wired network cards is configured with a fixed access dedicated network to support specific applications, and the other 1 wired network card or wireless The network card is configured to access the home network to support common applications.

In some embodiments, when the second network card of the smart TV is connected to the second network link, its controller writes the obtained second network card address into the second network card and the kernel, which can be specifically implemented as including obtaining the address based on the Android framework process. The network proxy class of the address of the second network card is written into the second network card and the kernel.

For example, the second network card is implemented as a second wired network card. When the second network cable interface corresponding to the second wired network card is inserted into the network cable access device, the controller will control the network daemon process to notify the Ethernet tracking class and create a factory class, and then pass the Internet The interconnection protocol control service obtains the IP address of the second wired network card based on the dynamic host configuration protocol;

After the IP address is successfully obtained, the controller will control the second wired network card to generate its corresponding network proxy object and register it in the network connection management service, and the network connection management service will use the IP address of the second wired network card Write it into the kernel and the second network card for invocation of Android framework services.

In some embodiments, the second network card is implemented as a second wireless network card, and the controller obtains the IP address of the second wireless network card through a traditional and commonly used Android framework process, and controls the generated network proxy class object to register with the network connection management service, and then The network connection management service writes the IP address of the network card into the kernel and the second wireless network card.

In some embodiments, the smart TV can be configured to have its first wired network card connected to the first network link, and its second wired network card connected to the second wired link.

For example, after the smart TV is connected to the above-mentioned network at the same time, its first video application can access the Internet and the wide area network through the second network link accessed by the second wired network card, wherein the second video application can also be implemented as other common applications, second and third video applications, and weather forecast applications, etc.; and the video intercom doorbell can now access the community dedicated network through the first network link of the first wired network card.

For another example, after the smart TV is connected to the above network at the same time, its first video application can access the Internet through the wireless link accessed by the second wireless network card, wherein the second video application can also be implemented as the second and third video applications , and weather forecast applications, etc.; at this time, the community video clinic can access the community dedicated network through the first network link of the first wired network card. Although the TV is connected to and uses two different networks through different network cards at the same time, the above two networks do not affect each other.

It should be noted that, the first network link and the second network link in the above embodiment can access the wide area network at the same time.

In some embodiments, the smart TV can also be configured with multiple wired network cards. For example, when both the second wired network card and the third wired network card are connected to the wired network, the controller will control the network card of the previously connected network to obtain an IP address and Connect to the network.

For example, when a wired network is connected to a smart TV, the controller will control the network daemon process to notify the Ethernet tracking class to deliver a message to the Ethernet factory class, and then obtain the information of the second wired network card and the third wired network card through the Internet Protocol control service. IP address;

After the IP address is obtained, the controller will control the dual wired network to generate a network proxy object and register it in the network connection management service;

The final score of the network connection management service determines which network to connect to, and then sends the message to the kernel; because the two wired networks have the same score, the wired network that is connected later in time will be eliminated, and the smart TV will be connected to the first connected network. wired network.

In some embodiments, the smart TV is equipped with a plurality of wired network cards, that is, wireless network cards, wherein the first wired network card is fixed for accessing a dedicated network; if the second wired network card and the second wireless network card are both connected to different networks, The controller will control the network card of the previously connected network to obtain an IP address and access the network.

For example, when the second wireless network card is connected to its corresponding wireless network, the controller will start the completion broadcast after the wireless network state machine receives the startup broadcast, and then create a wireless network factory class and register it in the network connection management service, The network connection management service further transmits a message to the network factory class, and the network factory class registers the obtained wireless network card address in the system network connection management service;

When the second wired network card accesses the corresponding wired network, the controller will control the network daemon process to notify the Ethernet tracking class, and the Ethernet factory class will register the obtained wired network card address in the network connection management service;

The network connection management service will determine which network to connect to based on the score of the network factory class; among them, the score of WIFI is lower than that of the wired network, so the controller will choose to connect to the wired network, and control the wireless network WIFI to turn off automatic reconnection.

In some embodiments, when the smart TV is turned on and the network cable interface corresponding to its wired network card is inserted into an accessible wired network, the controller will obtain the IP address of the wired network through the Android framework service, and then the controller will control to generate the corresponding IP address of the wired network card. Network proxy class object, and register it in the network connection management service;

After the wireless network card is also connected to the corresponding wireless network, after the controller obtains the IP address through the above method of obtaining the address of the wireless network card, the controller will control to generate a network proxy class corresponding to the network cable network card, and register the object to the network connection management service middle;

Finally, in the network connection management service, the controller controls the score to determine which network to connect to, and then sends a message to the system kernel, wherein the wireless network with a low score will be eliminated, and the controller finally controls the wired network card to access the corresponding wired network.

In some embodiments, when both the first wired network card and the second wireless network card used to access the dedicated network are connected to the network, the controller will make the first wired network card Each of the second wireless network card obtains its corresponding IP address, and accesses the corresponding network, so that the TV can simultaneously access the wired dedicated network and the common wireless network.

For example, the controller controls the first wired network card to obtain its corresponding IP address according to the above-mentioned embodiment, and checks whether the network node exists through the first service created by the controller; if it exists, it means that the first wired network card of the network node is ready; Start work until it controls the first service and then start the first wired network card, then obtain the IP address of the wired network card through the dynamic host configuration protocol client, and then obtain the first wired network card through the transmission message received by the dynamic host configuration protocol server. a wired network card IP address, and write the IP address information of the first wired network card into the first wired network card;

Corresponding to the second wireless network card that needs to access the ordinary wireless network, the controller controls the network card to obtain the IP address through the Android framework process described in the previous embodiment, and generates the corresponding network proxy class object for the obtained second wireless network card IP address , and register it in the network connection management service, and then the network connection management service writes the address of the second wireless network card into the system kernel and the second wireless network card.

According to the above technical solution, the display device provided by this application can realize that its Android system can be connected to two wired networks or one wired and one wireless network at the same time, and can obtain the corresponding IP address.

In some embodiments, the first wired network card and the second network card of the smart TV may also be implemented as different links for accessing the same local area network.

For example, the living room is equipped with two network ports for accessing the same network, the living room network port 1 and the living room network port 2; Then a wired link 1 connected to the first network card and a wired link 2 connected to the second network card are formed.

It can be understood that if there is a quality problem in the connection line between the living room network port 2 and the router, resulting in a drop in network bandwidth, but the quality of the connection line between the living room network port 1 and the router is normal, the TV will connect to the wired link 1 through the wired link 1. 2 Access to the network will produce a different network experience;

In this case, the third video application played and displayed by the smart TV on the foreground user interface accesses the LAN through the first wired network card, wired link 1, and living room network port 1, and the network bandwidth used by it will not be different from the living room network port. 2 is affected by the defective quality line connected; while the first video application and the second video application running in the background are connected to the LAN through the second network card, wired link 2, and living room network port 2, and the network bandwidth used by them is It will be affected and dropped due to the defective quality line connected to the living room network port 2.

Therefore, the above-mentioned technical solution enables the Android system TV to break through the current technical bottleneck, and can use multiple network access at the same time, for example, it can simultaneously access wired networks, WIFI networks, or simultaneously access two broadband networks that exist in the home environment. , or access from different network entrances of the same network, to avoid insufficient network bandwidth caused by multiple applications using the network at the same time, or network bandwidth degradation caused by the quality of specific network entrance lines.

It can be understood that the first wired network card described in this application can not only be fixedly connected to a dedicated network, but also be applicable to network interfaces with better quality fixed connection lines in the same local area network, so as to avoid problems caused by poor quality of some network lines in the home. The link network bandwidth drop problem ensures that the network links used by important applications are in good condition.

In some embodiments, it should be noted that generally, the user can allocate multiple available networks to multiple network cards of the TV. For example, for 2 TV-available networks and 2 network cards, the first network link with relatively good network quality can be allocated and connected to the first network card, and the other second network link can be allocated and connected to the second network card. In order to realize that the program that is in the foreground, that the user is watching, and that is currently the most important to the user can obtain data through a fixed dedicated first network link, so as to avoid the lack of network bandwidth caused by multiple applications starting at the same time, causing the program to freeze, etc. Bad web experience.

In some embodiments, the technical solutions described in this application can also be widely applied to dual-screen interaction, family services, full voice services, device control and active scene services, access to community capabilities, family doctor services, or music services, full voice services Interaction and scene engine, home appliance butler service, etc.

Compared with ordinary home appliances with Android system, the Android system only allows one kind of network connection and obtains IP address at the same time; network, such as community network and home network respectively.

It should be noted that the circuit board of the display device provided by itself can be equipped with three network cards to achieve simultaneous connection to two networks; the specific implementation is capable of accessing two wired networks and one wireless network wifi, of which there is a wired network The network is to be connected to the community network for calling elevators or video doorbell intercom. And another wired or wireless network is connected to the home network for accessing the WAN. Therefore, two different networks can be used at the same time. Community applications use the community network, and ordinary applications use the home network.
