Description

Display device, port scheduling method and storage medium

Technical Field

The present embodiments relate to a display technology, and more particularly, to a display apparatus, a port scheduling method, and a storage medium.

Background

Currently, since a display device can provide a user with a play picture such as audio, video, picture, and the like, it is receiving a wide attention of the user. With the development of big data and artificial intelligence, the functional requirements of users on display devices are increasing day by day. For example, the user performs a video chat with a friend while the user wants to play the display screen; or when the user is in a game scene, chatting with game teammates in real time; or, the user learns the current screen content in the education application program and simultaneously performs remote audio-video interaction with parents/teachers in real time, so as to meet the requirement of chatting while watching.

Based on the above-mentioned "chat while watching" requirement of the user, a communication connection may be established between the display device and an external device, for example, a mobile communication terminal of the user, and a picture or sound such as a video chat on the mobile communication terminal may be played on the display device, so as to satisfy that the user can perform the video chat while watching the video.

In the practical application process, the display device of the dual system can be selected to realize the functions. The dual system includes a first controller (a chip) and a second controller (N chip), and the first controller and the second controller may perform internal communication through an Interface module, such as an HDMI (High Definition Multimedia Interface), a network port, and a USB (Universal Serial Bus). The method comprises the steps that currently applied audio and video data are output to a display screen and a loudspeaker through a first controller to display video images and audio sounds, the externally applied audio and video data sent by an external device are decoded through a second controller, the processed data are sent to the first controller, and the first controller processes the processed audio and video data to synchronously output the currently applied audio and video data and the externally applied audio and video data on the display device.

However, in the above dual-system display device, only the second controller is located in the local area network where the external device is located, and can communicate with the external device, and the communication between the first controller and the external device needs to perform data forwarding through the second controller. When the first controller needs to communicate with the external device, a communication port is opened to receive and transmit relevant data, and the second controller is requested to synchronously open a corresponding port for data forwarding. Since the first controller and the second controller are two independent systems, the port opened by the first controller requesting the second controller may already be occupied by the application on the second controller, which will result in the first controller not being able to communicate with the external device, and thus the above-mentioned "chat while watching" function cannot be realized.

Disclosure of Invention

In view of the foregoing technical problems, an object of the present application is to provide a display device, a port scheduling method, and a storage medium.

A first aspect of embodiments of the present application shows a display device, including:

the system comprises a first controller, a second controller and a third controller, wherein the first controller is provided with a plurality of internal communication ports and is configured to select a first port to be opened from the internal communication ports, generate port information to be opened according to the first port and send the port information to be opened to the second controller;

a second controller provided with a plurality of external communication ports, the second controller being configured to detect whether a second port corresponding to the first port among the external communication ports is occupied according to the port information to be opened; if a second port corresponding to the first port in the external communication ports is occupied, sending port unavailable information to the first controller; if a second port corresponding to the first port in the external communication ports is not occupied, sending port available information to the first controller, and opening the second port in the second controller;

the first controller is further configured to replace a first port to be opened according to the port unavailability information, generate replaced port information to be opened, and send the replaced port information to be opened to the second controller; and opening the first port according to the port available information.

A second aspect of the embodiments of the present application shows a port scheduling method, where the method is applied to a display device, where the display device includes a first controller and a second controller, and the method includes:

the first controller selects a first port to be opened from internal communication ports of the first controller, generates port information to be opened according to the first port, and sends the port information to be opened to a second controller;

the second controller judges whether a second port corresponding to the first port in the external communication ports of the second controller is occupied or not according to the information of the port to be opened;

if a second port corresponding to the first port in the external communication ports is occupied, sending port unavailable information to the first controller;

if a second port corresponding to the first port in the external communication ports is not occupied, sending port available information to the first controller, and opening the second port in the second controller;

the first controller replaces a first port to be opened according to the port unavailable information, generates replaced port information to be opened, and sends the replaced port information to be opened to the second controller;

and the first controller opens the first port according to the port available information.

A third aspect of the embodiments of the present application illustrates a computer-readable storage medium, on which a computer program is stored, where the computer program, when executed by a controller, implements the port scheduling method according to the second aspect.

As can be seen from the foregoing technical solutions, embodiments of the present application illustrate a display device, a port scheduling method, and a storage medium. After the second controller receives the port which is requested to be opened by the first controller, whether the port corresponding to the port in the second controller is occupied or not is judged, if the port is occupied, the first controller is informed to replace one port, and if the port is not occupied, the corresponding port is opened to wait for data forwarding. Therefore, the method and the device have the advantages that whether the port which is requested to be opened by the first controller is occupied or not is fed back to the first controller by the second controller, the port which is requested to be opened is prompted to be replaced by the first controller when the port is occupied, and therefore the problem that communication between the first controller and external equipment fails due to the fact that the port corresponding to the port which is requested to be opened by the first controller is occupied is solved.

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 that receives the source code, data received by the camera cannot be displayed on a display screen of the display device.

Moreover, due to the hardware structure, the hardware system of the conventional display device only supports one hard decoding resource, and usually can support video decoding with a maximum resolution of 4K, so when a user wants to perform video chat while watching a network television, the user needs to use the hard decoding resource (usually a 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. a 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, multiple paths of 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).

The concept to which the present application relates will be first explained below with reference to the drawings. It should be noted that the following descriptions of the concepts are only for the purpose of facilitating understanding of the contents of the present application, and do not represent limitations on the scope of the present application.

As shown in fig. 6b, the application layer of the display device contains various applications that can be executed at the display device 200.

The N-chip application layer 2912 may include, but is not limited to, one or more applications such as: a video-on-demand application, an application center, a game application, and the like.

For example, a live television application may provide television signals using input from cable television, radio broadcasts, satellite services, or other types of live television services. And, the live television application may display video of the live television signal on the display device 200.

And a selector in the user interface indicating that the item is selected, the position of the selector being movable by user input to change the selection of a different item.

It should be noted that the multiple view display areas may present display screens of different hierarchies. For example, a first view display area may present video chat project content and a second view display area may present application layer project content (e.g., web page video, VOD presentations, application screens, etc.).

Optionally, the different view display areas are presented with different priority levels, and the display priority levels of the view display areas are different among the view display areas with different priority levels. If the priority of the system layer is higher than that of the application layer, when the user uses the acquisition selector and picture switching in the application layer, the picture display of the view display area of the system layer is not blocked; and when the size and the position of the view display area of the application layer are changed according to the selection of the user, the size and the position of the view display area of the system layer are not influenced.

Based on the above-mentioned need of "chat while watching" of the user, the present application may preset a port on the N chip of the display device, and forward data received by the port from the external device to the a chip, or forward data received by the port from the a chip to the external device. Since the port of the a chip that needs to communicate with the external device is usually not fixed, the N chip usually needs to set a plurality of different ports to implement data forwarding between the a chip and the external device. For example, the application 1 of the a chip needs to communicate with the external device through the port 111 of the a chip, the application 2 of the a chip needs to communicate with the external device through the port 222 of the a chip, the application 1,N card needs to forward data between the a chip and the external device through the preset port corresponding to the port 111, and the application 2,N card needs to open the preset port corresponding to the port 222 to forward data between the a chip and the external device. However, the application of the N chip itself may occupy the port corresponding to the port 111 or the port corresponding to the port 222 in the N card before the application 1 or the application 2 of the a chip, which will cause that when the data to be sent to the external device by the a chip reaches the port corresponding to the port 111 in the N chip, the data is forwarded to the application of the N chip itself, but not to the external device, or when the data to be sent to the a chip by the external device reaches the port corresponding to the port 222 in the N chip, the data is forwarded to the application of the N chip itself, but not to the a chip. Therefore, when the application of the N chip occupies a port of the N chip, which needs to perform data forwarding between the a chip and the external device, the a chip cannot successfully receive data sent by the external device.

In view of the above technical problem, a first aspect of the present application shows a display device, and in particular, may refer to fig. 8, where the display device 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 an internal communication port 311. The internal communication port 311 is a port configured in the first controller and capable of performing data communication with the second controller, and the internal communication port 311 may include a plurality of ports, each of which is provided with a port number, for example, the internal communication port a and the port number are 10001, the internal communication port b and the port number are 10002, …, the internal communication port n and the port number are 10999, and n is an integer greater than 0. Depending on the number of first controller applications, a number of internal communication ports 311 are assigned to different applications of the first controller for invocation thereby. For example, internal communication port a is configured to be callable by application a of the first controller, internal communication port B is configured to be callable by application B of the first controller, internal communication port m is configured to be callable by application m of the first controller, and so on.

The second controller comprises an external communication port 211. The external communication port 211 is a port of the second controller configured to communicate with an external device, the external communication port 211 may include the same number of ports as the internal communication port 311, and each port is provided with a port number, for example, the external communication port a and the port number are 10001, the external communication port b and the port number are 10002, …, the external communication port n and the port number are 10999, and n is an integer greater than 0. The external communication port 211 and the internal communication port 311 configured to have the same port number can perform data communication.

In the system of the second controller, a routing rule is added: in a routing pre-allocation stage, data received by a designated port is forcibly intercepted, the data is not allowed to enter a system of a second controller for processing, and the data is enabled to be forwarded to a port corresponding to a first controller through a FORWARD rule, so that the data sent by all external equipment can reach the first controller, and the condition of data loss is ensured not to occur. For example, it is specified that the external communication port a with the port number of 10001 in the second controller is forcibly intercepted and forwarded to the internal communication port a with the port number of 10001 in the first controller, so that the first controller can successfully receive the data sent by the external device.

The above technical solution is simple to implement, but may affect the application in the second controller, for example, a certain application in the second controller already uses 10001 of the external communication port a for communication, at this time, since a certain application in the first controller also uses the external communication port a for communication, a FORWARD rule that all data received by the external communication port a is forwarded to the external communication port a of the first controller is generated in the second controller, although the application of the first controller can receive data of an external device and perform further processing, the application in the second controller that monitors the external communication port a cannot receive a data packet sent by the external device to the first controller, and cannot communicate with the external device until the application in the first controller that uses 10001 of the external communication port a exits.

To solve the technical problem in the first aspect, a second aspect of the present application illustrates a display device, and in particular, may refer to fig. 9, the display device includes a first controller and a second controller.

Here, for convenience of description, the first controller in fig. 4 and 5 corresponds to the first controller in fig. 9, and the second controller in fig. 4 and 5 corresponds to the second controller in fig. 9. Which will not be indicated further below.

The first controller includes an internal communication port 311 and a first control schedule 315. The internal communication port 311 is a port configured in the first controller and capable of performing data communication with the second controller, and the internal communication port 311 may include a plurality of ports, each of which is provided with a port number, for example, the internal communication port a and the port number are 10001, the internal communication port b and the port number are 10002, …, the internal communication port n and the port number are 10999, and n is an integer greater than 0. Depending on the number of first controller applications, a number of internal communication ports 311 are assigned to different applications of the first controller for invocation thereby. For example, internal communication port a and internal communication port B are configured to be called by application a of the first controller, and internal communication port n is configured to be called by application B of the first controller.

The first control schedule 315 is an application monitoring program preset by the first controller, and the first control schedule 315 is configured to monitor an application process of the first controller. When an application program on the first controller needs to communicate with the external device, the application program selects an internal communication port which can be called and is not occupied from the first controller as a first port to be opened, and calls an open port command to open the first port, wherein the call open port command comprises information of the port to be opened, and the information of the port to be opened comprises the port number of the first port. The first control schedule 315 monitors the open port commands from the application processes of the first controller and intercepts the open port commands, thereby preventing the open port commands from opening the first port. After intercepting the port opening command, the first control schedule 315 obtains the information of the port to be opened of the port opening command.

After acquiring the information of the port to be opened, the first control schedule 315 sends the information of the port to be opened to the second controller. In an embodiment, the first control schedule 315 generates a port opening request according to the information of the port to be opened, and sends the port opening request to the second controller, so as to facilitate the second controller to perform processing.

The second controller includes an external communication port 211 and a second control schedule 215. The external communication port 211 is a port configured to communicate with an external device in the second controller, the external communication port 211 may include the same number of ports as the internal communication port 311, each port is provided with a port number, for example, an external communication port a and a port number 10001, an external communication port b and a port number 10002, …, an external communication port n and a port number 10999, and n is an integer greater than 0. The external communication port 211 and the internal communication port 311 configured to have the same port number can perform data communication.

The second control schedule 215 is a port control program preset by the second controller, and the second control schedule 215 is configured to communicate with the first control schedule 315 of the first controller. When the first control schedule 315 sends the information of the port to be opened or the port opening request, the second control schedule 215 processes the information of the port to be opened or the port opening request to obtain the port number of the first port to be opened by the first controller.

After acquiring the port number of the first port, the second control schedule 215 detects the external communication port 211 of the second controller to acquire the port state of the second port having the same port number as the first port, and the detection method is as follows: traversing and comparing the first port with an external communication port on the second controller, wherein the port state of the external communication port is occupied; and judging whether the occupied external communication port is a second port corresponding to the first port, wherein the second port corresponding to the first port refers to a second port with the same port number as the first port.

If the occupied external communication port is a second port corresponding to the first port, the second control schedule 215 generates port unavailability information; the port unavailable information is sent to the first control schedule 315 of the first controller. If the occupied external communication ports are not the second ports corresponding to the first ports, the second control schedule 215 generates port available information, the second ports are opened in the second controller, after the second ports are opened, the second control schedule 215 monitors the second ports, if the data monitored by the second ports are the data sent by the external devices, the data are forwarded to the first ports, and if the data monitored by the second ports are the data sent by the first ports, the data are forwarded to the external devices.

After receiving the port unavailability information, the first control schedule 315 of the first controller generates port binding failure information according to the port unavailability information, and sends the port binding failure information to an application program calling the first port on the first controller. After receiving the port binding failure message, the application program calling the first port on the first controller will replace an internal communication port that it can call and is not occupied as a new first port, and then the second control schedule 215 of the second controller will determine whether the new first port is available, and if the new first port is not available, the first controller will replace a first port again until receiving the port availability message.

The first control schedule 315 of the first controller, upon receiving the port availability information, opens the first port to enable the first port to communicate with the second port.

To describe in detail the data communication process between the first controller and the second controller in the second aspect, a third aspect of the present application shows a port scheduling method, specifically, see fig. 10, the method is applied to a display device, where the display device includes a first controller and a second controller, and the method includes the following steps:

step S100: the first controller and the second controller respectively carry out preprocessing after being started.

The preprocessing of the second controller includes step S101: a second control schedule is initiated. The second control schedule resides in a background process of the second controller after startup.

The preprocessing of the first controller includes step S102 and step S103.

Step S102 is to start the first control schedule. The first control schedule resides in a background process of the first controller after startup, facilitating timely communication with the second control schedule of the second controller.

Step S103 is to start the application. The application launch time of the first controller is after the launch time of the first control schedule, facilitating the first control schedule being able to monitor the application of the first controller.

Step S110: the first controller selects a first port to be opened from the internal communication ports of the first controller, generates port information to be opened according to the first port, and sends the port information to be opened to the second controller.

Step S110 includes step S111 and step S112.

In step S111, a first port to be opened is selected, and a port opening command is generated according to the first port information. For example, the application a of the first controller selects an internal communication port a with a port number of 10001 as the first port to be opened, and generates an open port command including the port number of 10001.

Step S112 is to intercept the port information to be opened, and send the port information to be opened to the second controller. For example, after intercepting the port opening command, the first control schedule of the first controller acquires the port number 10001 from the port opening command, and sends the port number 10001 to the second controller.

Step S120: and the second controller judges whether a second port corresponding to the first port in the external communication ports of the second controller is occupied or not according to the information of the port to be opened.

Step S120 includes step S121 and step S122.

In step S121, port information to be opened is received. And the second control scheduling of the second controller receives the information of the port to be opened sent by the first control scheduling of the first controller to obtain the port number of the first port to be opened of the first controller. For example, the second control schedule of the second controller obtains the port number of the first port from the port information to be opened as 10001.

Step S122 is to determine whether a second port corresponding to the first port among the external communication ports of the second controller is occupied. And the second control scheduling of the second controller respectively performs traversal comparison on the port number of the opened port in the external communication port and the port number of the first port, and judges whether a second port with the same port number as the first port exists in the opened port in the external communication port. For example, if the second control schedule of the second controller obtains the port numbers of all the opened ports in the external communication ports to be 10001 and 10999, the opened port with the port number of 10001 is the second port corresponding to the first port, or if the second control schedule of the second controller obtains the port numbers of all the opened ports in the external communication ports to be 10002 and 10999, the opened port in the external communication ports does not have the second port with the same port number as the first port.

Step S130: and sending port unavailable information to the first controller if a second port corresponding to the first port in the external communication ports is occupied.

If the port state of the second port with the same port number as the first port is obtained in step S122 as opened, the second control schedule of the second controller generates port unavailability information, and sends the port unavailability information to the first control schedule of the first controller, where the port unavailability information includes the port number of the first port and a preset identifier that the port is unavailable. For example, the port numbers of all opened ports in the external communication ports are 10001 and 10999, including the port number 10001 of the first port, the second port with the port number 10001 of the second controller is not available, and the first controller is notified by generating the port unavailability information, where the port unavailability information is (10001,1) and 1 is a preset identifier indicating that the port is unavailable.

Step S140: and if a second port corresponding to the first port in the external communication ports is not occupied, sending port available information to the first controller, and opening the second port in the second controller.

Step S140 includes step S141 and step S142.

In step S141, the port availability information is sent. The second control schedule of the second controller sends the port availability information to the first control schedule of the first controller. The port availability information includes a port number including the first port and a preset identification that the port is available. For example, if the port numbers of all the opened ports in the external communication ports are 10002 and 10999, excluding the port number 10001 of the first port, the second port with the port number 10001 of the second controller is available, and the first controller is notified by generating port availability information (10001,0), and 0 is a preset identifier indicating that the port is available.

Step S142: the second port is opened. And the second control schedule of the second controller opens the second port, so that the second port can receive the data sent by the external equipment or the data sent by the first port. Furthermore, after the second port is opened by the second control scheduling, the second port is monitored, so that when the second port receives data sent by the external equipment, the data is timely forwarded to the first port, or when the second port receives the data sent by the first port, the data is timely forwarded to the external equipment.

Step S150: and the first controller acquires the port state of the second port according to the port available information or the port unavailable information.

Step S150 includes step S151 and step S152.

In step S151, port unavailable information or port available information is received. And the first control schedule of the first controller receives the port unavailable information or the port available information sent by the second control schedule of the second controller.

Step S152 is to determine whether the second port is available. The first control schedule of the first controller determines that the second port is unavailable based on the port unavailability information and determines that the second port is available based on the port availability information. For example, it is determined that the second port having the port number 10001 is unavailable from the reception (10001,0) in step S151, and it is determined that the second port having the port number 10001 is available from the reception (10001,1) in step S151.

Step S160: and sending port unavailable information to the first controller if a second port corresponding to the first port in the external communication ports is occupied.

The first control schedule of the first controller may directly send the port unavailability information to an application calling the first port in the first controller, and the application may be configured to acquire the information that the first port is unavailable according to the port unavailability information.

Furthermore, port binding failure information can be generated according to the port unavailability information, so that an application program calling the first port in the first controller can conveniently acquire the information that the first port is unavailable according to the port binding failure information and the port calling rule. The port binding failure information includes a port number of the first port and a port binding failure identifier. For example, the port binding failure information is (10001, bind error), and the bind error is the port binding failure flag.

Step S180 (not shown in fig. 9): the first controller replaces the first port to be opened according to the port unavailable information, generates replaced port information to be opened, and sends the replaced port information to be opened to the second controller.

And the application program calling the first port in the first controller replaces one first port according to the port unavailable information or the port binding failure information. For example, the application program calling the first port in the first controller is application program a, and according to the port binding failure information, application program a selects the internal communication port b with the port number of 10002 as the first port to be opened, and repeats steps S110 to S150 to determine whether the second port with the port number of 10002 is available.

Step S170: the first controller opens the first port according to the port availability information.

If the information available for the second port is obtained in step S1502, the first port is opened directly, that is, the work of the port opening command intercepted in step S112 is completed, so that the application program calling the first port in the first controller can communicate with the second port of the second controller through the first port. For example, if a second port with a port number of 10001 is available, the first control schedule of the first controller opens the first port with the port number of 10001, or the second port with the port number of 10002 is available, the first control schedule of the first controller opens the first port with the port number of 10002.

As can be seen from the foregoing embodiments, embodiments of the present application illustrate a display device, a port scheduling method, and a storage medium. After the second controller receives the port which is requested to be opened by the first controller, whether the port corresponding to the port in the second controller is occupied or not is judged, if the port is occupied, the first controller is informed to replace one port, and if the port is not occupied, the corresponding port is opened to wait for data forwarding. Therefore, the method and the device have the advantages that whether the port which is requested to be opened by the first controller is occupied or not is used for feeding back the first controller, the port which is requested to be opened is prompted to be replaced by the first controller when the port is occupied, and therefore the problem that communication between the first controller and external equipment fails due to the fact that the port corresponding to the port which is requested to be opened by the first controller is occupied is solved.
