Changes in the network make the CEC network experience poor. The management of the network node is clear and convenient, and the state information of the nodes in the network is updated in time, so that the user can timely understand the changes of the network and improve the experience of the CEC network.

In the existing CEC technology, the status of the nodes (CEC devices) in the network cannot be monitored, so that the information of the status of each node in the network cannot be known in time, and the management of the nodes in the network is confusing, so that the user cannot know the network in time. The changes made the CEC network experience poor.

Based on the above problems, the present invention provides a method for managing network node information.

Referring to FIG. 2, FIG. 2 is a schematic flowchart diagram of a first embodiment of a method for managing network node information according to the present invention.

In an embodiment, the method for managing network node information includes:

Step S10, after successfully creating a tree structure of each node in the network to form a tree of each node in the network, traversing the formed tree, and acquiring information of each node is saved in the backup tree and displayed on the user interface;

Obtaining the relationship between nodes in the network, constructing a tree structure between the nodes according to the relationship between the nodes to form a tree of each node in the network. The CEC device is assigned 14 logical addresses according to the HDML 1.4a standard document, that is, there are up to 14 devices in the CEC network, that is, there are at most 14 nodes in the tree structure. After the tree is formed, it is determined whether the tree is successfully created. If the tree is not formed successfully, the tree is re-formed according to the relationship between the nodes of the network. After the value of the number of times of re-formation is greater than the preset threshold, the preset threshold may be It is 2 or 4 times, etc., according to the user's needs and/or system performance settings, the prompt message that the tree formation fails. The prompt information may be text, picture, voice, etc.; after the tree structure of each node in the successfully created network forms a tree of each node in the network, traverse the formed tree, and obtain information of each node to save to the backup tree. And displaying the acquired information of each node in the user interface, and displaying the acquired information of each node in a tree structure. The acquired information of each node includes, but is not limited to, pointer information pointed by the node, a logical address of the current node, a physical address of the current node, a connection state of the current node, a standby state of the current node, and the like.

Specifically, the process of obtaining a physical address of the node may include: sending a <give physical After the message of address>, the target CEC device will return its own physical address.

The process of obtaining the logical address of the node may be: since the underlying driver also needs a logical address when sending the message, as long as a message is sent, the logical address can be extracted according to the received message.

The process of obtaining the connection state of the node may be: the connection state may be processed by sending a message. If the result of sending any message is successful, the CEC device (node) is connected, otherwise it is not connected.

The acquisition process of the node standby state may be: in the CEC network, a <GIVE POWER may be sent. The STATUS> message causes the target CEC device to return its status and update this status information to the node.

Referring to FIG. 3, it is a schematic diagram of a tree structure of a CEC topology network. The name of each node in the tree is the physical address of the node, and the physical address is allocated by the underlying driver. For each of these nodes, the definition is as follows: a pointer to the parent node, a pointer to the child node 1, a pointer to the child node 2, a pointer to the child node 3, a pointer to the child node 4, a pointer to the child node 5, The physical address of the current node, the logical address of the current node, the connection state of the current node, the standby state of the current node, and so on. Regarding the acquisition of pointers, depending on the actual state of the CEC network, for most products, the number of HDMI ports will not exceed five, so designing five sub-nodes is sufficient, regardless of the complex tree structure. In other embodiments of the present invention, it is also possible to design more than five child nodes or less than five child nodes, and design according to actual conditions.

The node pointer itself belongs to a part of the tree. Through the tree's related logical operations, the tree's ancestor pointer, parent pointer, and child pointer can be easily obtained.

Step S20, detecting status information of each node in the tree, and determining whether the status information changes;

After the tree is successfully created, the state information of each node in the tree is detected. In order to prevent the excessive consumption of resources and the update status of the node state, the state information of each node in the tree is detected when the preset time is reached. The time is preferably 1 s. In other embodiments of the present invention, other 2s, 3s, and the like may also be set according to system resource distribution and system performance and/or user needs. After detecting the state of the node in the tree, it is determined whether the state information changes.

Specifically, referring to FIG. 4, the process of determining whether the status information changes may include:

Step S21: determining whether there is a node in the formed tree; determining whether there is a node in the formed tree, that is, determining whether the formed tree has a node and whether it is an empty tree.

Step S22: When there is no node in the formed tree, determine whether a node exists in the backup tree.

Step S23, when there is a node in the backup tree, determining that the state information changes;

When there is no node in the formed tree, it is further determined whether there is a node in the backup tree corresponding to the formed tree, and when there is a node in the backup tree, it is determined that the state information changes.

Step S24, when the node exists in the formed tree, compare the detected state information with the state information of the node in the backup tree;

Step S25: When the detected state information does not match the state information of the node in the backup tree, it is determined that the state information changes.

When the node exists in the formed tree, the detected state information is further compared with the state information of the node in the backup tree, and when the detected state information is inconsistent with the state information of the node in the backup tree, The status information changes; if they are consistent, it is determined that the status information has not changed, and the status information of each node in the formed tree is continuously detected. For example, when the connection state of the node changes, and/or when the connection state of the current node changes or when the physical address of the current node changes, it is determined that the state information changes; all information of the node does not change. At the time, it is judged that the state information has not changed.

In other facts of the present invention, it may be determined whether the state information changes according to the number of nodes in the formed tree.

Specifically, referring to FIG. 5, the process of determining whether the status information changes according to the number of nodes in the formed tree may be:

Step S26, comparing the value of the number of nodes of the formed tree with the value of the number of nodes in the backup tree;

Step S27: When the value of the detected number of nodes does not match the value of the number of nodes in the backup tree, it is determined that the state information changes.

First, by detecting the number of nodes in the formed tree, comparing the value of the detected number of nodes with the value of the number of nodes in the backup tree, if the value of the detected number of nodes is different from the number of nodes in the backup tree. Then, it is judged that the status information changes.

Step S30, when the status information changes, update the information of each node according to the changed status information, and display the updated information on the user interface.

When the state changes, the state information that has changed is acquired, the information of each node is updated according to the changed state information, and the updated information is displayed on the user interface. For example, the connection state of the node, the standby state of the node, the physical address of the node, and the like are updated. The updated information is stored in the formed tree.

After successfully displaying the updated information on the user interface, performing step detection of status information of each node in the tree and determining whether the status information changes. That is, after the status information is updated and displayed on the user interface, the status information of each node in the formed tree is continuously detected. The mechanism of delay detection is used to ensure the integrity of the information, that is, after the update is completed, it can be ensured that the benchmark of the next detected data is the same, for example, the same as the data in the backup tree.

In this embodiment, a tree is formed by constructing a tree structure of the network node, and information of each node in the tree is saved to the backup tree; state information of each node in the tree is detected, and when the detected node information changes, the tree is updated. The node information displays the updated information in the user interface. Effectively avoiding the existing CEC technology, it is impossible to monitor the status of nodes (CEC devices) in the network, so that the information of the status of each node in the network cannot be known in time, and the management of the nodes in the network is confusing, which makes the user unable to know in time. Changes in the network make the CEC network experience poor. The management of the network node is clear and convenient, and the state information of the nodes in the network is updated in time, so that the user can timely understand the changes of the network and improve the experience of the CEC network.

Referring to FIG. 6, FIG. 6 is a schematic flowchart diagram of a second embodiment of a method for managing network node information according to the present invention. Based on the first embodiment of the foregoing method for managing network node information, after the step S21, the method further includes:

Step S28, when there is no node in the formed tree, the tree is created according to the node information of the network.

If there is no node in the formed tree, that is, when the formed tree is an empty tree, it is necessary to create a tree according to the node information of the network.

In other embodiments of the present invention, when the status information changes frequently, in order to ensure the real-time performance of the tree information, it is also necessary to re-create the tree of each node in the network. The process of determining that the state information changes frequently may be: determining whether the value of the number of times the state information changes in a certain time is within a preset threshold, and the certain time may be 1 minute, 2 minutes, etc. according to user needs and/or System performance settings, which may be 5 times, 10 times, etc., depending on system performance and/or network status settings. When the value of the number of times of change is within the preset threshold, it is determined that the state information does not change frequently, and when the value of the number of times of change is not within the preset threshold, the state information is often changed. In this embodiment, when the state information of the node in the tree changes frequently or when the tree is empty, the tree is created, and the real-time performance of the tree information is improved, so that the user can timely know the information of each node device in the network, and improve the information. The experience of the CEC network.
