FIG. 1A is a flow chart of a data processing method according to an embodiment of the present invention. As shown in fig. 1A, the data processing method may include the steps of:

step S102, determining a target network address associated with the distributed system.

In the technical solution provided in the step S102, the distributed system is configured to play a target video, and the data stored in the target network address is configured to synchronize video data between a first node device in the distributed system and one or more second node devices in the distributed system, where the video data may be a video stream, including a video main code stream and a video auxiliary code stream.

The distributed system is used for playing the target video, and may include a first node device and one or more second node devices, which may be any node device in the distributed system, may be an input node device (encoding Encoder node), and may be an output node device (decoding Decoder node). Optionally, the node device may be an agent node device or a large screen node device.

Alternatively, the distributed system of this embodiment may include an agent system, a large screen management system, and a central control system supported by the professional audiovisual domain. FIG. 1B is a schematic diagram of a distributed system according to an embodiment of the present invention. As shown in fig. 1B, the distributed system 10 may include an agent system 11, a large screen management system 12, and a central control system 13 supported by a professional audiovisual domain.

In this embodiment, the agent system 11 may be configured to output an interaction result corresponding to an interaction request of the terminal device to the target video, where the interaction request may be a request for indicating a user service requirement. Alternatively, the agent system 11 of this embodiment is a system that performs service demand interaction with other subsidiary systems of the call center and terminal devices on behalf of service operation and management, and the agent system 11 may be classified into a local agent, a remote agent, a legacy agent, and an international protocol (Internet Protocol, abbreviated as IP) according to different classifications. According to the embodiment, through the agent system, operations such as inquiring, suggesting and the like of the target video can be performed on the interaction request which is sent by the user through the terminal equipment, so that more convenient service is provided for the user.

The embodiment determines a target network address associated with the distributed system, where the target network address may be a network address preset by the distributed system and shared by a plurality of node devices to implement communication, and data stored on the target network address is used to enable automatic synchronization of video data between a first node device in the distributed system and one or more second node devices in the distributed system, instead of being performed by a server, where the stored data may include device information of the node devices, and may also include video data of the node devices, where the device information may be a device address of the node devices. Alternatively, the destination network address of this embodiment may be a multicast address of the distributed system, for example, a fixed multicast network protocol (IP) address, which may also be referred to as a networking address, which is used to indicate that all information receivers can join a group, and once joined, data flowing to the multicast address starts to be transmitted to the receivers immediately, and all information receivers in the group can receive the data.

Wherein one or more second node devices and the first node device may be in the same network environment, e.g. in the same local area network environment.

The first node device of this embodiment may receive video data of one or more second node devices at the target network address, or may acquire video data transmitted from the one or more second node devices to the first node device based on the device information of the first node device stored at the target network address.

Optionally, other node devices in the distributed system of the embodiment may record not only the video data of the node device of the other node devices by using the method described above, but also acquire the video data of the other node devices, that is, each node device in the distributed system records the video data of all the node devices, so that automatic synchronization of data is achieved, a main server is not required, and data is automatically synchronized between the node devices, so that topology information of all the node devices in the distributed system is consistent, and even if any node device damages the data, the data is not lost.

Step S106, playing the target video based on the video data of the first node device and the video data of the one or more second node devices.

In the technical scheme provided in the step S106 of the present invention, after the video data of one or more second node devices is obtained based on the data stored in the target network address, the first node device may play the target video based on the video data of the first node device and the video data of one or more second node devices together, so as to display the complete picture of the video, avoid the problem of data loss caused by damage of any node device, improve the safety, stability and reliability of video playing, and have strong expandability.

When an output node device takes over a corresponding terminal device (e.g., a computer), a connection with a corresponding input node device for Keyboard Mouse (KM) control may be requested. Note that, the exclusive mode needs to request from the master node device whether or not the master node device can be exclusive.

As another alternative example, the first node device may be an input node device, and the input node device may push the primary and secondary streams of the local video onto corresponding multicast addresses; output node equipment (such as large screen node equipment) in the distributed system can calculate a video source which is required to be used according to the large screen configuration information and the layer information, decode the video source, scale the video source, and display the scaled video source at a fixed position; meanwhile, the output content of the large-screen node equipment can be encoded, and multicast plug flow is transmitted to the local area network for software use.

The video stream, the KM control data, the large screen layer data, the scene data and the switching data of the embodiment are not required to be transmitted through a main node and a server, but can be directly transmitted between corresponding input node equipment and output node equipment, so that the normal use of other node equipment is not influenced when any node equipment in the system fails.

A distributed system is composed of a plurality of node devices, for example, an input node device and an output node device, and as a whole, data among all the node devices needs to be synchronized in real time. The distributed system of the embodiment adopts a decentralization design idea, and does not need an independent server and a management node, and node equipment in the whole distributed system can synchronize video data through a target network address, so that the management of the node equipment is realized. Any node equipment is bad, normal use of the node equipment in the distributed system is not affected, and because a separate server and a management node are not additionally used, the cost of the distributed system is reduced, and the system is safe, stable and reliable and has strong expandability.

Example 2

The above technical solution of this embodiment is further exemplified below.

Fig. 2 is a schematic diagram of a distributed system according to an embodiment of the present invention. As shown in fig. 2, the distributed system includes an input node device (encoding Encoder node device), an output node device (decoding Encoder node device), a switch, and an upper computer. A plurality of output node devices form a seat, and each seat is provided with a set of keyboard and mouse; and the plurality of output node devices form a large-screen controller, and the large-screen controller jointly displays the same large-screen video picture in a carrying way. The large screen controlled by the large screen controller can be a light emitting diode (LightEmitting Diode, simply called an LED) large screen or a liquid crystal display (Liquid Crystal Display, simply called an LCD).

Optionally, the distributed system mainly comprises an agent system, a large screen management system and a central control system.

FIG. 3 is a schematic diagram of another distributed system according to an embodiment of the present invention. As shown in fig. 3, the distributed system is composed of a plurality of input node devices and output node devices, wherein the input node devices may be the Encoder node devices, and the output node devices may be the Encoder node devices. The input node equipment and the output node equipment can transmit data through a switch, and the input node equipment can be connected with computers, servers, notebooks and other equipment.

Distributed systems as a whole system, data between all node devices is used requiring real-time synchronization. In the related art, most of the distributed systems require an additional main server to be configured in addition to the input node device and the output node device as a main device of the distributed system, so as to achieve data synchronization between the node devices. This is costly on the one hand, and if the primary server fails on the other hand, the entire distributed system is completely paralyzed.

In another related art, for a distributed system that does not need a separate configuration server, a node device needs to be separately designated as a management node, and critical data is stored in the management node, so that the distributed system is relatively dependent on the running state of the management node, which is easy to cause a bottleneck, and when the management node is abnormal, the data of the whole system is lost.

However, the distributed system of this embodiment adopts the design concept of decentralization, does not need a separate server, and does not need to separately designate a node device as a management node, so that the whole distributed system can perform data synchronization and node management. The data are synchronized in real time among the node devices, and the normal use of other node devices in the distributed system is not affected if any node device is damaged. The other aspect also solves the problem of high cost of the distributed system. The method of this embodiment is further described below.

The two types of data are stored in a classified mode, the purpose of decentralizing a distributed system is achieved, and meanwhile, data interaction between node devices does not occupy a large bandwidth.
