Description

Method for ensuring stable communication between two systems and display equipment

Technical Field

The present application relates to the field of dual system communication technologies, and in particular, to a method and a display device for ensuring stable communication between dual systems.

Background

In the use of the dual-system device, in order to coordinate the capabilities of two systems therein and achieve the coordination and consistency of interaction between the two systems, communication is often required to be established between the two systems, which is used for transmitting information data between processes in the two systems and achieving function switching between the two systems. Therefore, the capabilities of the two systems can be better utilized only if there is a smooth communication between the two systems.

At present, to ensure the communication efficiency between two systems in a dual-system device, a network is usually used to connect the two systems in the dual-system device, that is, the communication between the two systems in the dual-system device is realized by a network (Net) direct connection manner. However, dual-system devices, such as dual-system televisions, often have ac/dc standby power-on, STR (Suspend to RAM, memory standby mode) standby power-on, and the network state cannot be stable for a long time, so serial communication is also provided between two systems in the dual-system devices. Since the two systems in the dual-system device have the HDMI channel for transmitting the video signal, a CEC (Consumer Electronics Control) channel of the HDMI (High Definition Multimedia Interface) channel may be multiplexed to transmit data, that is, the two systems in the dual-system device may communicate with each other through the CEC. Therefore, in order to improve the communication capability between two systems in the dual-system device, three communication modes, namely Net, serial port and CEC, are usually set between the two systems.

However, in use, it is found that, for example, network change, serial device initialization, and CEC device initialization at the boot stage all affect the communication link, and it is not guaranteed that the communication link is always in a connected state. How to implement real-time communication and communication stability between two systems in dual-system devices such as display devices according to the state of a communication link is a technical problem to be solved urgently by technical personnel in the field.

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).

The concept to which the present application relates will be first explained below with reference to the drawings.

Since the functions of the operating system 3911 of the a chip are similar to those of the operating system 2911 of the N chip, reference may be made to the operating system 2911 for relevant points, and details are not repeated here.

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. The application layer 3912 of the a-chip may include, but is not limited to, one or more applications such as: live television applications, media center applications, and the like. It should be noted that what applications are respectively contained in the a chip and the N chip is determined according to an operating system and other designs, and the present invention does not need to make specific limitations and divisions on the applications contained in the a chip and the N chip.

The live television application program can provide live television through different signal sources. 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.

A video-on-demand application may provide video from different storage sources. Unlike live television applications, video on demand provides a video display from some storage source. For example, the video on demand may come from a server side of the cloud storage, from a local hard disk storage containing stored video programs.

The application center may obtain these applications from different sources, store them in local storage, and then be operable on the display device 200.

A schematic diagram of a user interface in a display device 200 according to an exemplary embodiment is illustrated in fig. 7. As shown in fig. 7, the user interface includes a plurality of view display areas, illustratively, a first view display area 201 and a play screen 202, wherein the play screen includes a layout of one or more different items. 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 priorities, and the display priorities of the view display areas are different among the view display areas with different priorities. 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.

The display frames of the same hierarchy can also be presented, at this time, the selector can switch between the first view display area and the second view display area, and when the size and the position of the first view display area are changed, the size and the position of the second view display area can be changed along with the change.

Since the a-chip and the N-chip may have independent operating systems installed therein, there are two independent but interrelated subsystems in the display device 200. For example, Android and various APPs can be independently installed on the chip a and the chip N, so that each chip can realize a certain function, and the chip a and the chip N cooperatively realize a certain function. The communication between the N system and the Client (Client) in the A system realizes the data transmission between the N system and the Client (Client) in the A system. In the embodiment of the present application, intercommunication between the N system and the a system is referred to as dual system communication (abbreviated as HiRPC). The dual-system communication is realized through a Net, a serial port and a CEC (consumer electronics control) channel, namely the dual-system communication has Net, serial port and CEC modes.

In the embodiment of the present application, Net, serial port, and CEC respectively have a communication Server (Server) corresponding thereto, such as: net has NetServer, serial port has SerialServer, CECServer, and the Server of Net, serial port and CEC constitutes a Server cluster. In the embodiment of the application, the same access port is provided for the Client based on Net, serial port and CEC, the difference of the device types is shielded, and a uniform interface is provided for the upper layer. In the specific embodiment of the application, the NetServer has a plurality of NetServer1, NetServer2 and NetServer 3, when the communication is established through the NetServer, the Client in the dual system can select any NetServer to connect; the serialServer and CECServer are respectively located at each end of the dual system, when communication is established through the serialServer and CECServer, the Client in the dual system is connected with the serialServer and CECServer at the end where the Client is located, and the corresponding serialServer and CECServer are respectively connected, as shown in FIG. 8. Client1 and Client2 are located in two systems, respectively, in fig. 8.

As can be seen from fig. 8, the maintenance of the communication mode between the two systems is the result of maintaining the connection between each Client and the Server and the corresponding Server in the two systems. Only if the connection state between the Client and the Server is clearly known, the monitoring of the corresponding states of the Net communication mode, the serial communication mode and the CEC communication mode can be achieved, the stability of communication between the Client and the Server is ensured, the real-time communication between two systems in dual-system equipment such as display equipment can be realized, and the stability of communication between the two systems is ensured.

Therefore, in the embodiment of the present application, although there are Net, serial port and CEC channel to implement communication between the dual-chip system, it cannot be guaranteed that Net, serial port and CEC are always in a connected state, for example: the STR standby Net is disconnected, the network abnormal physical path is disconnected, the Net is unavailable, the serial port physical path is abnormal, the serial port physical path is unavailable, the CEC physical path is abnormal, and the CEC physical path is unavailable. If the abnormal communication channel cannot be found in time, the data transmission will be carried out through the semi-connected Server, and the communication of the semi-connected Server is unavailable, so that the timeliness of the data transmission will be affected, and the communication between the two systems is unstable.

In order to realize real-time communication between two systems in dual-system equipment such as display equipment and ensure the stability of communication between the two systems, the embodiment of the application provides a method for ensuring the stability of communication between the two systems. Fig. 9 is a schematic flowchart of a method for ensuring stable communication between two systems according to an embodiment of the present application, where the method is used at a Server side.

As shown in fig. 9, a method for ensuring stable communication between two systems according to an embodiment of the present application includes:

s101: when the Server is connected with the Client, the Server receives live pkg circularly sent by the Client.

When the Server is connected with the Client, the Client circularly sends live pkg to the Server, the Server receives the live pkg circularly sent by the Client, and the time when the Server receives the live pkg is recorded. In the embodiment of the application, the live pkg is used for informing the receiving end that the receiving end is still online, that is, when the Client needs to maintain communication, the live pkg is sent to the Server which maintains the connection with the Client, and the Server receives the live pkg sent by the Client, which indicates that the communication between the Client and the Server is in a connection state.

In this embodiment, a cyclic sending live pkg is respectively established in the Server and the Client, and is used to implement the cyclic sending live pkg between the Server and the Client, and to circularly inform the other side of its own status, and determine whether the corresponding communication between the Server and the Client still maintains connection.

In the embodiment of the application, the time interval of live pkg sent by the Client to the Server in a cycle can be selected to be 4S, and the time interval of live pkg sent by the Server to the Client in a cycle can be selected to be 4S. Therefore, the time interval for the Server to receive the live pkg cyclically transmitted by the Client may be 4S, and the time interval for the Client to receive the live pkg cyclically transmitted by the Server may be 4S. In the embodiment of the application, the time interval of live pkg sent by the Client to the Server in a cycle may be selected to be 4S, but is not limited to 4S, and may be selected according to actual needs.

S102: the time at which the live pkg was received was monitored.

Recording the time of receiving live pkg circularly transmitted by the Client by the Server, and monitoring the time of receiving the live pkg. Namely, the time of last receiving the live pkg is monitored from the current time, and whether the time of receiving the live pkg circularly transmitted by the Client by the Server is within a normal range is judged. The normal range may be a time threshold set empirically or on demand, with less than or equal to the interval threshold being within the normal range and greater than the time threshold being outside the normal range. In this embodiment of the present application, a timeout threshold may be selected, that is, the time distance between the last time when the live pkg is received and the current time is less than or equal to the timeout threshold, and the time when the Server receives the live pkg sent by the Client in a cyclic manner is within a normal range, otherwise, the time is not within the normal range. The timeout threshold is greater than the time interval of live pkg cyclically transmitted by the Client to the Server, for example, when the time interval of live pkg cyclically transmitted by the Client to the Server is 4S, the timeout threshold may be selected to be 8S, but is not limited thereto.

In the embodiment of the application, when the time of receiving the live pkg circularly sent by the Client by the Server is within a normal time range, namely the time of last receiving the live pkg by the Server is less than or equal to the overtime threshold from the current time, continuing to monitor the time of receiving the live pkg; when the time for the Server to receive the live pkg circularly sent by the Client exceeds the normal time range, that is, the time distance between the Server and the last time when the live pkg is received is greater than the timeout threshold, step S103 is executed.

S103: and when the time distance between the last time when the live pkg is received and the current time length is greater than a timeout threshold value, disconnecting the Server from the Client.

When the time length from the last time that the Server receives live pkg to the current time is monitored to be larger than the overtime threshold, it is indicated that the connection corresponding to the current Server has a problem and needs to be disconnected. Therefore, when the current time length of the time distance of the last time of receiving live pkg by the Server is monitored to be larger than the overtime threshold, the connection between the Server and the Client is disconnected, and the Client is effectively prevented from communicating through the semi-connected Server.

In the embodiment of the present application, the servers include a NetServer, a SerialServer, and a CECServer, and no matter which Server is used, the connection condition of the current physical path can be dynamically monitored by the above method for ensuring stable communication between the two systems. When the network is used, the two ends are normally communicated, if a network card at one end is disconnected, the TCP connection kept at the two ends can detect the disconnection of the TCP at the end with the disconnected network card, but the disconnection of the TCP can not be detected at the opposite end, namely the TCP can not capture the abnormality, but the abnormality can be detected by a strategy of receiving live pkg circularly sent by the Client through the Server. Meanwhile, aiming at the aging and damage of hardware in the operation process of the dual-system equipment, the physical disconnection can be detected in real time by the method for ensuring the communication stability between the dual systems, and then the connection is disconnected.

Therefore, the method for ensuring stable communication between the two systems provided by the embodiment of the application realizes dynamic monitoring of the connection state between the Server and the Client, fully considers the scenes of alternating current and direct current switching on and off, STR standby, acoustic mode, network abnormity, serial abnormity and CEC abnormity between the two systems, can achieve the purpose of monitoring the states of corresponding Net, serial and CEC communication modes, timely finds out unavailable communication modes, avoids communication between the Client and the Server through semi-communication between the Server and the Client, realizes real-time communication between the two systems in the dual-system equipment such as display equipment and the like, and ensures the stability of communication between the two systems.

In the embodiment of the application, when the Server receives a Discover message sent by the Client, the Server sends a Notify message to the Client for the Server to actively inform the Client of the own state of the Client, so that the Client can know the existence of the Server, and then the Client can actively connect the Server, thereby realizing the corresponding connection of the Server and ensuring the communication stability between two systems.

In the method for ensuring stable communication between two systems provided in the embodiment of the present application, the method further includes: when the Server is the NetServer, monitoring the network state; and when the network disconnection is monitored, disconnecting the connection between the Server and the Client.

Therefore, the network state is monitored, and when the network state changes and the state is communicated to the network from the network and is not communicated, the connection between the Server and the Client is disconnected, so that the control of the connection between the NetServer and the Client is realized according to the network state. Therefore, when the Server is a NetServer, in addition to the method provided by the above embodiment, the method further includes a specific control method thereof, so that a Net channel is more accurately monitored, communication between the Client and the Server through a semi-connected NetServer is avoided, and the communication stability between the two systems is more ensured.

Further, when the NetServer monitors that the network is reconnected, namely the network is not communicated with the network, the NetServer sends a Notify message to the Client; the NetServer actively informs all the clients through the Notify message, and the clients can know that the NetServer exists at present and then connect the NetServer. Therefore, more communication mode selections are provided for communication between two systems in the dual-system equipment, dynamic selection and scheduling of the communication modes between the two systems are convenient to achieve, and real-time communication between the two systems in the dual-system equipment such as the display equipment and the stability of communication between the two systems are further guaranteed.

In the method for ensuring stable communication between two systems provided by the embodiment of the application, when the Server is a serialServer, the Server receives live pkg circularly sent by the ServeralServer at the opposite end of the Server;

monitoring the time of receipt of the live pkg;

Further, when the Server receives the live pkg circularly sent by the SerialServer at the opposite end of the Server again, the Notify message is sent to the Server;

and establishing the connection between the Server and the Client.

In the method for ensuring stable communication between two systems provided in the embodiment of the present application, when the Server is a CECServer, the Server receives live pkg cyclically sent by the CECServer at the opposite end of the Server;

monitoring the time of receipt of the live pkg;

Further, when the Server receives the live pkg circularly sent by the CECServer at the opposite end of the Server again, the Notify message is sent to the Server;

and establishing the connection between the Server and the Client.

For the serial port and the CEC, both ends of the dual system need to be provided with the Server, because only the Server has the capability of operating the serial port and the CEC, the Client and the Server are connected through a local network loop. For the physical path, each Server has a state for indicating online or offline, when the Server state is online, the physical path is detected to be disconnected (CEC, serial port path) by using a live pkg mechanism circularly sent between the Client and the Server, the Server is set to be in the offline state, and all the clients are informed that the Server is offline, and the Server is not selected to transmit data. When the connection is detected from disconnection, the Server sends live pkg to the opposite Server, so that the Server can detect that the disconnected physical path is connected, the state of the Server is set to be in an online state, then all clients are informed that the Client is online, and the Client can select the Server to transmit data.

Fig. 10 is a schematic structural diagram of a serial port dynamic notification online and offline status, and the dynamic notification online and offline status process of CEC refers to the serial port, which is not described herein again. The following describes how to dynamically notify the online and offline status by taking a serial port as an example, with reference to fig. 10. Sending the SerialServer to an opposite terminal SerialServer; monitoring the time when the opposite terminal SerialServer receives the live pkg; when the time distance between the last time that the SerialServer receives the live pkg and the current time length is monitored to be larger than the overtime threshold, the SerialServer at the opposite end is considered to be offline, a Notify message is sent to the Client to inform the SerialServer at the opposite end of the offline, the SerialServer at the local end is offline, and the Client is disconnected from the SerialServer; when the SerialServer receives live pkg circularly sent by the SerialServer of the opposite end again, the SerialServer of the opposite end is considered to be online again, the SerialServer of the local end sends a Notify message to the Send Notify message to inform that the SerialServer of the opposite end is online, the SerialServer of the local end is online, the connection between the Client and the SerialServer is established, and the serial port communication is available.

The serial port transmission depends on hardware communication, and the serial port can communicate after the operating systems at the two ends are started. However, the two systems have different starting time sequences, and the simultaneous starting to the same moment cannot be guaranteed. Therefore, verification must be added to ensure the connectivity of the serial ports on both sides. When the serial port service is just started, the serial port servers connected with the clients are in an off-line state by default, and after the servers send live pkg to the opposite-end servers to judge that the two ends are communicated, all connected clients are actively informed that the current serial port servers are on line. In the running process of the dual-system equipment, serial port hardware is damaged to cause that serial ports can not be communicated, the equipment can timely detect that the serial ports are not communicated and inform all connected clients that the current serial port Server is offline, so that the communication between the clients and the Server through the semi-communicated serialServer is avoided, and the communication stability between the dual systems is ensured.

The embodiment of the application also provides a method for ensuring stable communication between the two systems, which is used for the Client terminal. Fig. 11 is a flowchart illustrating a method for ensuring stable communication between two systems according to this embodiment.

As shown in fig. 11, a method for ensuring stable communication between two systems according to an embodiment of the present application includes:

s201: when the Client is connected with the Server, the Client receives live pkg circularly sent by the Server.

S202: monitoring the time of receipt of the live pkg;

s203: and when the time distance between the last time when the live pkg is received and the current time length is greater than a timeout threshold value, disconnecting the Client from the Server.

In the method for ensuring stable communication between two systems provided by this embodiment, the Server actively sends live pkg to the Client in a circulating manner, and the Client monitors the time for receiving the live pkg, so as to monitor the communication state corresponding to the Server. For specific details of the method for ensuring stable communication between two systems provided in this embodiment, reference may be made to the method for ensuring stable communication between two systems provided in the above embodiment for the Server side, which is not described herein again.

Further, in the method for ensuring stable communication between two systems provided in the embodiment of the present application, the method further includes:

when the Client does not have a Server connected with the Client, the Client sends a Discover message to the Server cluster;

when a Server in the Server cluster receives the Discover message, sending a Notify message to the Client;

and establishing the connection between the Client and the Server.

And when the Client finds that the communication state of the connected Server is abnormal, actively disconnecting the Client from the corresponding Server. When the Client breaks the connection with the corresponding Server and finds that no available Server exists on the Client, the Client sends a Discover message to the Server cluster, when the Server in the Server cluster receives the Discover message, the Client sends a Notify message to the Client, the Server actively informs the Client of the own state, the Client knows the existence of the Server, and then the Client can actively disconnect the Server, so that the connection of the corresponding connection of the Server is realized, and the communication stability between two systems is ensured.
