Detailed Description

To make the objects, technical solutions and advantages of the exemplary embodiments of the present application clearer, the technical solutions in the exemplary embodiments of the present application will be clearly and completely described below with reference to the drawings in the exemplary embodiments of the present application, and it is obvious that the described exemplary embodiments are only a part of the embodiments of the present application, but not all the embodiments.

For the convenience of users, various external device interfaces are usually provided on the display device to facilitate connection of different peripheral devices or cables to implement corresponding functions. When a high-definition camera is connected to an interface of the display device, if a hardware system of the display device does not have a hardware interface of a high-pixel camera receiving the source code, data received by the camera cannot be displayed on a display screen of the display device.

Furthermore, due to the hardware structure, the hardware system of the conventional display device only supports one path of hard decoding resources, and usually only supports video decoding with a resolution of 4K at most, so when a user wants to perform video chat while watching a network television, the user needs to use the hard decoding resources (usually GPU in the hardware system) to decode the network video without reducing the definition of the network video screen, and in this case, the user can only process the video chat screen by using a general-purpose processor (e.g. CPU) in the hardware system to perform soft decoding on the video.

The soft decoding is adopted to process the video chat picture, so that the data processing burden of a CPU (central processing unit) can be greatly increased, and when the data processing burden of the CPU is too heavy, the problem of picture blocking or unsmooth flow can occur. Further, due to the data processing capability of the CPU, when the CPU performs soft decoding on the video chat screen, multi-channel video calls cannot be generally implemented, and when a user wants to perform video chat with multiple other users in the same chat scene, access is blocked.

In view of the above aspects, to overcome the above drawbacks, the present application discloses a dual hardware system architecture to implement multiple channels of video chat data (at least one channel of local video).

Since the operating systems, such as the android system, running on the processor 210 in fig. 4 and 5 and the processor 310 in fig. 4 and 5 default to control the wired Network port to be used as WAN (Wide Area Network) ports, two systems on the display device 200 may respectively access external communication networks in different Network segments, so that communication between the two systems cannot be performed.

In view of the above technical problem, a first aspect of the present application shows a display device, and in particular, referring to fig. 8, a display device 200 includes a first controller and a second controller.

Here, for convenience of description, the processor 210 in fig. 4 and 5 has a corresponding relationship with the first controller in fig. 8, and the processor 310 in fig. 4 and 5 has a corresponding relationship with the second controller in fig. 8. Which will not be indicated below.

The first controller includes a first portal 315. The first port 315 is a wired port, and the port is used as a WAN (wide area Network) port. The first controller may be configured to obtain an IP address of the first network segment for the first portal 315 from a Dynamic Host Configuration Protocol (DHCP) server after the second controller starts the DHCP server. The first network segment is an IP address segment of an internal communication network of the display device 200, the first network segment is set to be different from a second network segment, the second network segment is an IP address segment of an external communication network of the display device 200, the external communication network is a communication network of a router to which the display device 200 is connected, the second network segment of the external communication network is determined by the router, and is usually a 53.0 address segment, of course, the first network segment may be set to be a 47.0 address segment, and the second network segment may be other IP address segments.

The second controller comprises a plurality of second network ports 215, and the second network ports 215 are all wired network ports. One of the second Network ports 215 is used as a WAN (Wide Area Network) port, which is called an external communication Network port, and is denoted as eth0, and the external communication Network port can be connected to a router through a Network cable to access an external communication Network.

The remaining second network ports 215 of the second controller are used as LAN ports, which are called internal communication network ports and are denoted as eth1, eth2, … …. The first portal 315 is connected to an internal communication portal enabling the first controller to communicate with a second controller, the internal communication network being the communication network between the second controller and the first controller.

Because the operating system running on the second controller, such as the android system, defaults to control the plurality of wired network ports to be used as WAN ports, in order to enable the second network port 215 to be used as a LAN port, the application obtains the operating command of the system process of the operating system to the internal communication network port after the second controller is started; the operation command of the internal communication network port is shielded, and then two services are additionally arranged to control the internal communication network port. The operation command comprises a command such as an enable command, a disable command and a command for monitoring the state change of the network port, wherein the enable command is a command for converting the state of the network port of the wired network port from a down state to an up state, the disable command is a command for converting the state of the network port of the wired network port from the up state to the down state, and the command for monitoring the state change of the network port is a command for monitoring the state change of the network port from the disable state to the enable state or from the enable state to the disable state. The method for shielding the operation command comprises the steps of annotating the code of the operation command by using an if statement, and if the operation command of the internal communication network port is monitored, annotating the operation command to prevent the operation command from being executed.

As shown in fig. 9, after the android system on the second controller is started, the second controller obtains a default network interface of the current system of the second controller and all wired network ports. The default network interface of the current system is eth0, and all wired network interfaces include eth0, eth1 and … …. And marking the default network interface of the current system as an external communication network port, marking other wired network ports as internal communication network ports, and shielding the internal communication network ports, wherein X represents shielding.

After the android system is started, the system process can send out enabling commands to all wired network ports, and the enabling commands of the internal communication network ports are annotated by using if sentences. And in the subsequent operation process of the android system, monitoring the operation command of the wired network port in the system process in real time, and if the operation command of the internal communication network port is monitored, annotating the operation command by using the if statement.

After the operation command of the system process to the wired network port other than the external communication network port is shielded, the service one and the service two pairs of the internal communication network ports set by the embodiment are used for controlling, wherein the service one and the service two are two init (kernel self-starting) services set on the second controller.

Service one can be defined in the init.rc file of the android system and set it as auto-launch. As shown in fig. 10, the control method for serving a pair of second controllers includes the steps of:

step S110: and judging whether the internal communication network port exists or not.

All the second network ports 215 in the display apparatus 200 may be acquired from the installation system kernel through an ifconfig statement, such as eth1, eth2, … …, and if the number of the second network ports 215 is greater than 1, it is determined that the second network ports 215 as the internal communication network ports exist, and if the number of the second network ports 215 is equal to 1, it is determined that the second network ports 215 as the internal communication network ports do not exist. When no internal communication network port exists, the service can be finished.

The display device 200 provided with the first controller and the second controller may be provided with a plurality of second network ports 215 in the second controller, for example, one of the second network ports 215 is used as an external communication network port, and the other second network ports 215 are used as internal communication network ports, however, there may be some display devices 200, where the first controller and the second controller both have only one wired network port, that is, the first controller has only one first network port 315, the second controller has only one second network port 215, the second network port 215 of the second controller needs to be used as an external communication network port to access an external communication network, and the internal communication network port of the second controller will not exist, so that the first controller cannot be communicatively connected with the second controller through the first network port 315, and the first controller also needs to access the external communication network port 315. Whereas for a display device 200 comprising only one second controller without a first controller, the second controller may be provided with only one second portal 215, which second portal 215 needs to access the external communication network as an external communication portal, the internal communication portal of the second controller will not be present. Therefore, whether the internal communication network port exists or not is judged, and the problem that the second controller cannot access the external communication network due to the fact that the second network port 215 is mistakenly controlled as the internal communication network port when the number of the second network ports 215 of the display device 200 is only one can be avoided, so that the networking process of the display device 200 cannot be interfered when the display device 200 with the number of the second network ports 215 being only one runs, and the range of the display device 200 suitable for the service is widened.

For the display device 200 provided with a plurality of second ports 215, there may be a case where a certain second port 215 cannot be detected in time at a certain moment, for example, the second port 215 cannot be detected due to power failure, and therefore, when it is determined that an internal communication port does not exist, it may be set to continuously determine whether the internal communication port exists, and when the internal communication port exists, the next step is performed.

Step S120: and judging whether the internal communication network port is in an enabling state or not.

When the internal communication network port exists, the second controller can acquire the network port state of the internal communication network port from the android system kernel through the ifconfig statement, judge whether the network port state is an enabled state, and when the internal communication network port is in the enabled state, the second controller can control the internal communication network port to communicate with the first network port 315. At a certain moment, the network port state of the internal communication network port may be in a non-enabled state, and if the second network port 215 is powered down again, the network port state may be in the non-enabled state.

When the internal communication network port is in the disable state, the second controller can be used for converting the network port state of the internal communication network port into the enable state.

Step S130: and if the internal communication network port is in an enabling state, controlling the external communication network port to acquire the IP address of the second network segment from the external communication network.

If the internal communication port is in the enabled state, it indicates that the internal communication port can be controlled to be in communication connection with the first port 315, so that the first controller and the second controller can perform data interaction, and at this time, the IP address of the second network segment can be acquired from the external communication network through the external communication port, so that the display device 200 can access the external communication network. Of course, it may also be arranged that after the first controller is started, the second controller is controlled to obtain the IP address of the second network segment from the external communication network through the external communication port.

Step S140: and starting the DHCP server, and distributing the IP address of the first network segment for the internal communication network port through the DHCP server.

The DHCP server is provided on the second controller, and can operate based on services such as android netd (network daemon) service, dnsmasq (domain name configuration tool), and the like. After the external communication port acquires the IP address of the second network segment, the DHCP server may allocate an IP address of the first network segment to the first controller, so that the first controller becomes a device in the internal communication network of the display device 200. Since the first controller to which the second controller is connected in the display apparatus 200 is generally fixed, the first controller may be assigned a fixed IP address, facilitating monitoring of the IP address of the first controller.

Step S150: and setting the first controller to be in communication connection with an external device in an external communication network through the second controller.

After the first controller becomes a device in the internal communication network of the display device 200, the IP address field where the external device is located is the first network segment, and the IP address field where the external device is located in the external communication network is the second network segment, so that the first controller and the external device can interact with each other through the second controller by configuring an iptable (firewall).

The content of the iptable configuration includes: setting a DHCP address network segment range as a first network segment, connecting a first controller with an internal communication network port through a first network port to acquire an IP address of the first network segment, so that the first controller sends a first data packet with a source address being the IP address of the first network segment to a second controller, or receives a second data packet with a destination address being the IP address of the first network segment from the second controller; setting the content of the NAT service may include: according to a first data packet received from a first controller and the destination address of the first data packet is the IP address of an external device, the first data packet is forwarded to an external communication network port of a second controller, the external communication network port sends the first data packet to an external communication network, and according to a second data packet received from the external communication network and the destination address of the second data packet is the IP address of a first network segment, the second data packet is forwarded to an internal communication network port and then sent to the first controller; and (3) setting an ipforward (ip forwarding) service to enable the android system kernel to support the data packet forwarding function.

Step S160: service two is initiated.

In order to avoid the situation that the first service cannot be communicated with the external equipment after being cleaned by the android system, the second service is further arranged to guarantee the operation of the first service.

As shown in fig. 11, the control method of serving two-to-one second controller includes the steps of:

step S210: and judging whether the internal communication network port is in an enabling state or not.

And acquiring the internet access state of the internal communication internet access from the android system kernel through the ifconfig statement, and judging whether the internet access state is an enabling state. If the network port state of the internal communication network port is the disable state, the network port state of the internal communication network port is continuously judged.

Step S220: if the network port state of the internal communication network port is the enabling state, starting the socket to monitor the state change of the internal communication network port.

And monitoring the equipment state reported by the system kernel through a netlink (socket) to obtain the states of the internet access, wherein the states comprise add and remove, the add is regarded as an enabled state, and the remove is regarded as a disabled state.

Step S230: and switching from the enabling state to the disabling state according to the network port state of the internal communication network port, and restarting the service I.

When the port state of the internal communication port is converted from the enabled state to the disabled state, the DHCP server serving the one setting and the configuration, ipforward service, NAT service and route forwarding rule for the internal communication port are disabled, so that the second controller cannot guarantee the communication between the first controller and the external device. Since the service-side can convert the port status of the internal communication port from the disabled status to the enabled status, the port status of the internal communication port can be restored to the enabled status by restarting the service-side. And restarting the service I, namely after the network port state of the internal communication network port is restored to the enabled state, reconfiguring the internal communication network port, starting an ipforward service, an NAT service and a route forwarding rule, and ensuring the communication between the first controller and the external equipment.

Further, if the service is not started successfully, the internal communication network port and the external communication network port may both acquire the IP address of the second network segment, or the IP address of the internal communication network port is cleared by the android system, for example, the IP address of the internal communication network port caused by abnormal restart of the android system is cleared by the android system

Therefore, the second service can judge the IP address of the internal communication network port besides detecting the network port state conversion of the internal communication network port, and when the IP address of the internal communication network port is detected not to be the IP address of the first network segment, the first service can be restarted, so that the internal communication network port can obtain the IP address set by the first service.

To further describe the control scheme of the wired portal of the display device 200 of the dual system, the second aspect of the present application provides a wired portal control method, as shown in fig. 12, including the following steps:

step S310: the second controller sets one of the second network ports of the second controller as an external communication network port, and the rest of the second network ports are internal communication network ports.

Wired network ports which are set by default in the android system are WAN ports, one wired network port is a default network port, the default network port of the current system can be marked as an external communication network port, and other wired network ports are marked as internal communication network ports.

Step S320: and controlling the external communication network port to access the external communication network.

And controlling an external communication network port to acquire the IP address of the router in the external communication network of the display equipment through the second controller, wherein the IP address is the IP address of the second network segment.

Step S330: and controlling an internal communication network port to access an internal communication network of the second controller through a DHCP server arranged on the second controller.

After the external communication network port obtains the IP address of the second network segment, the DHCP server can be started to distribute the IP address of the first network segment for the internal communication network port, so that the first network port connected with the internal communication network port can obtain the IP address of the first network segment.

Step S340: and arranging the first controller to be in communication connection with an external device in an external communication network through the internal communication network port.

The internal communication network port is set as a data interface of the second controller in butt joint with the first controller, and the iptable is configured by setting a DHCP address network segment range, NAT service and ipforward service, so that the first controller is in communication connection with external equipment in an external communication network through the internal communication network port, and communication between the first controller and the external equipment is guaranteed.

As can be seen from the above embodiments, embodiments of the present application illustrate a display device, a wired network port control method, and a storage medium. The embodiment of the application discloses a display device, a wired network port control method and a storage medium. The second controller is accessed to an external communication network, and a first network port of the first controller is in communication connection with an internal communication network port in a second network port of the second controller, so that the second controller controls the first controller to be accessed to the internal communication network of the second controller through a DHCP server, and the problem that the first controller cannot communicate with the second controller possibly due to the fact that the first controller is also accessed to the external communication network is avoided; furthermore, the first controller is controlled to be in communication connection with the external equipment in the external communication network through the internal communication network port through setting, so that communication between the first controller and the external equipment is guaranteed.
