Description

A media streaming transmission method, device and electronic device based on edge device

[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office of China on August 30, 2023, with application number 202311110372.5 and invention name “A media streaming transmission method, device and electronic device based on edge devices”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present invention relates to the field of video transmission, and in particular to a media stream transmission method, apparatus and electronic device based on edge devices. Background Art

[0003] During the packaging and packing process in the logistics warehouse, a video recorder or camera will film and record the operator's actions on the workbench. After the user receives the package, if the package is damaged or other abnormalities occur during delivery, the video recording can be provided as evidence to prove that no damage was caused to the items during the packaging or loading and unloading process.

[0004] To ensure the reliability of video recording, a real-time video preview window will be provided on the operating system of the monitoring end page for operators to monitor whether the video recording is running normally. When the operator finds that the packaging operation equipment has an abnormality, he can promptly repair or replace other recordable equipment.

[0005] Because all operational processes must be continuously displayed during real-time video recording, existing solutions require recorders or cameras to connect to the public network via standard protocols. This can significantly consume network bandwidth in warehouses with large packaging volumes, requiring simultaneous recording and playback at numerous workstations. Furthermore, because video media streams are transmitted over the public network, network instability can occur, impacting monitoring effectiveness.

[0034] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0035] The technical solution provided by the embodiment of the present invention is applied to a media stream live broadcast system, or a media stream system for live broadcasting of logistics packaging process.

[0036] As shown in Figure 1, the system includes: a station device management (SDM) cloud module, an AIoTVideo cloud module, at least one client, an SDM edge device, an AIoTVideo edge device, at least one network video recorder (NVR), and at least one camera module, such as a camera.

[0037] Among them, AIoT is AI+IoT, that is, the integration of artificial intelligence technology and the Internet of Things in practical applications. The AIoTVideo visual network recording cloud module refers to an AIoT cloud device with video recording function; similarly, the AIoTVideo visual network recording edge device refers to an AIoT edge device with video recording function.

[0038] In addition, the SDM cloud module (SDM_Cloud) and / or the AIoTVideo cloud module can be a network device, such as a server or server cluster, or a gateway, etc., which is not limited in this embodiment.

[0039] The at least one NVR includes NVR1, NVR2, .... Each NVR uses one or more channels to connect to different camera modules. For example, NVR1 uses channel 1 to connect to camera module 1 and uses channel 2 to connect to camera module 2. Similarly, NVR2 uses channel 3 to connect to camera module 3 and uses channel 4 to connect to camera module 4, and so on.

[0040] The camera module includes but is not limited to a camera, and may also be other devices with photo taking / recording functions.

[0041] The functions of each module are as follows:

[0042] The SDM cloud module is responsible for managing the metadata of video devices and providing an entry point for business systems to use video devices, such as: viewing video device status, viewing real-time video, viewing recordings, downloading recordings, etc.

[0043] The SDM edge device (SDM_Edge), also known as the edge gateway, is responsible for communicating with the AIoTVideo edge device and reporting its information to the cloud for scheduling by the AIoTVideo cloud module.

[0044] The AIoTVideo cloud module (AIoTVideo_Cloud) is responsible for connecting to the video recorder device, managing the device status, and interacting with control commands.

[0045] The AIoTVideo edge device (AIoTVideo_Edge) is responsible for receiving the stream push and transcoding from the edge-side video recorder.

[0046] The network video recorder (NVR) is responsible for connecting to camera devices, storing recordings, and connecting to the cloud to provide video preview and playback.

[0047] Furthermore, the above-mentioned devices are wirelessly connected. Specifically, the SDM cloud module and the AIoTVideo cloud module communicate using HTTP (Hyper Text Transfer Protocol); at least one NVR and the AIoTVideo cloud module communicate using Socket protocol; at least one NVR and the AIoTVideo edge device communicate using Socket protocol; the SDM edge device and the SDM cloud module communicate using Socket protocol; the SDM edge device and the AIoTVideo edge device communicate using HTTP protocol.

[0048] Optionally, the SDM edge device and the AIoTVideo edge device are separated into two devices, or they can be integrated into the same device. In this case, the SDM edge device and the AIoTVideo edge device are two functional modules integrated into one device, which can be called an "edge all-in-one machine".

[0049] Typically, NVRs use the GB28181 protocol (GB28181 is a national standard for video surveillance) to establish a connection with a cloud signaling service. To play real-time video, the NVR transmits video data to the cloud via the public network, and users then retrieve the corresponding video media stream data from the cloud. However, when there are a large number of workstations and a large amount of video media streams to play, this can consume a significant amount of public network bandwidth, potentially leading to network congestion, transmission delays, and unstable real-time video playback.

[0050] In order to solve the above-mentioned technical problems, the technical solution provided in the embodiment of the present application provides a media streaming transmission method based on edge devices. The method pre-divides the various devices mentioned above into two networks, namely a first network and a second network, wherein the first network includes: an SDM cloud module and an AIoTVideo cloud module. The second network includes: an SDM edge device, an AIoTVideo edge device, at least one NVR, and at least one camera module. In addition, the first network and the second network may also include other more or fewer modules / devices, which are not limited in this embodiment.

[0051] In addition, at least one client can be set in the first network or in the second network. For example, the first client (client1) is located in the first network and the second client (client2) is located in the second network. This embodiment does not limit this, but this embodiment takes the client located in the second network as an example.

[0052] Optionally, the first network may be referred to as a public network, or outside the warehouse, and the second network may be referred to as a private network, such as a local area network, or inside the warehouse.

[0053] In this embodiment, by setting up SDM edge devices and SDM edge streaming services (AIoTVideo cloud module) in the warehouse, when playing real-time videos in the warehouse, the media stream data is transmitted through the private network with the help of SDM edge devices. When on the public network, the video is pulled through the public network with the help of cloud live broadcast, thereby saving public network bandwidth resources.

[0054] Example 1

[0055] 2 , a method for transmitting media streams based on edge devices is provided in this embodiment. The method includes the following steps:

[0056] Step 100: In the preparation phase, each NVR sends registration information to the AIoTVideo cloud module to register at least one NVR in the cloud network.

[0057] One implementation method is that each NVR registers the camera module information using the GB28181 protocol on the AIoTVideo cloud module. Further, specifically including:

[0058] The NVR sends channel information to the AIoTVideo cloud module. The channel information includes a channel identifier and a national standard ID. The channel refers to the communication link between each camera module and the NVR it is connected to. The channel representation can be an IPC (Internet Protocol Camera) camera, which is a network protocol-based camera also known as a webcam or network surveillance camera. It uses a network connection (such as Ethernet) to transmit video and audio data and communicate with other devices over the network.

[0059] In addition, the national standard ID is used to identify each channel, such as national standard ID 1 and national standard ID 2. Optionally, the national standard ID can be a string consisting of numbers, letters, and symbols.

[0060] The preparation phase also includes: after receiving the channel information, the AIoTVideo cloud module generates video device information and sends the video device information to the SDM cloud module. After receiving the video device information, the SDM cloud module saves the video device metadata, i.e., the video device information.

[0061] Video device information includes at least one parent-child relationship. For example, if NVR1 is connected to two camera modules, the corresponding device identifiers are IPC1 and IPC2, so a parent-child relationship is established: NVR1-IPC1&IPC2. Similarly, each other NVR and its connected camera module IPC can be established and this information can be stored in the SDM cloud module.

[0062] The method provided in this embodiment is described in detail below.

[0063] As shown in FIG2 , the media stream transmission method includes:

[0064] Step 101: The client sends an edge live broadcast request message to the SDM cloud module via a designated channel; correspondingly, the SDM cloud module receives the live broadcast request message from the client.

[0065] The live broadcast request message includes the camera module identifier for the live broadcast request. For example, the camera module identifier is IPC1 or channel 1, indicating a request to obtain the live media stream from IPC1, or a request to obtain the live media stream of IPC1 connected to channel 1.

[0066] The client is a client located in the second network. The client can be a terminal device, including but not limited to various personal computers (PCs), laptops, smart phones, tablet computers, etc.

[0067] Step 102: The SDM cloud module sends the live broadcast request message to the edge device to request at least one NVR to obtain the media stream.

[0068] Step 103: After receiving the live broadcast request message sent by the SDM cloud module, the edge all-in-one device generates media stream service information according to the camera module identifier.

[0069] The media stream service information includes the edge live broadcast URL (Uniform Resource Locator), the IP address of the edge device, and the port (port number) used by the edge device to receive the media stream. The IP address of the edge device and the port (port number) used to receive the media stream can be pre-set and stored on the edge device for use when generating the media stream service information.

[0070] Step 104: The edge all-in-one machine sends the media stream service information to the SDM cloud module.

[0071] Correspondingly, the SDM cloud module receives the media stream service information fed back by the edge all-in-one machine, and the media stream service information includes: edge live broadcast address URL, IP address and port of the edge all-in-one machine and other contents.

[0072] Step 105: The SDM cloud module sends the media stream service information and the camera module identifier to the AIoTVideo cloud module. The media stream service information is obtained in step 104, and the camera module identifier is obtained in step 101.

[0073] Step 106: The AIoTVideo cloud module receives the media stream service information and the camera module identifier, and requests the target NVR corresponding to the camera module identifier to obtain the media stream based on this information.

[0074] Specifically, the AIoTVideo cloud module determines the target NVR based on the camera module identifier, and then sends an invite request to the target NVR to request the media stream from the target NVR. The invite request includes the IP address of the edge device and the port on which the edge device receives the video / media stream.

[0075] Furthermore, one implementation of the AIoTVideo cloud module determining the target NVR is that the AIoTVideo cloud module searches for an NVR associated with the current IPC1 based on the camera module identifier, such as at least one pre-stored parent-child relationship (the video device information stored in the aforementioned preparation phase) for IPC1, and uses this NVR as the target NVR. In this example, assuming that IPC1 is associated with NVR1, i.e., a parent-child relationship exists, the target NVR is NVR1.

[0076] Step 107: When IPC1 is turned on, it captures the surrounding environment, records and generates a media stream, and pushes the media stream to the edge all-in-one device through the target NVR.

[0077] Correspondingly, the edge all-in-one device receives and stores the media stream pushed by the target NVR in real time.

[0078] Step 108: The target NVR returns a response to the AIoTVideo cloud module based on the invite request in step 106. The response may indicate a successful request or an unsuccessful request.

[0079] Correspondingly, the AIoTVideo cloud module receives the response and makes a judgment. If the AIoTVideo cloud module receives a message indicating that the request is successful, such as receiving a response, it means that the invitation is successful, and step 109 is executed.

[0080] If the AIoTVideo cloud module does not receive a response, it means that the request is unsuccessful, the request fails, and the process ends. Furthermore, whether the request is successful can be indicated and determined by the fields or identification codes in the response.

[0081] Step 109: The AIoTVideo cloud module sends the message indicating the successful request in step 108 (i.e., the response) to the SDM cloud module.

[0082] Step 110: After receiving the successful request message, the SDM cloud module sends the edge live broadcast address URL to the client. Optionally, the URL is also called the edge live broadcast address URL.

[0083] Step 111: After receiving the edge live broadcast address URL, the client requests the edge all-in-one machine to obtain the media stream through the edge live broadcast address URL.

[0084] Step 112: The edge appliance sends the media stream received in step 107 to the client according to the URL.

[0085] The client receives the media stream and uses the client's playback software to play the media stream in real time, thereby achieving live broadcast of the media stream on the client.

[0086] The method provided in this embodiment deploys the edge device on an edge all-in-one machine in the second network (local area network), establishes a long connection with at least one cloud module in the first network, such as the SDM cloud module and the AIoTVideo cloud module. When the client needs to request edge live broadcast in the local area network, the media stream recorded by the camera module is received through the edge all-in-one machine, and the edge all-in-one machine receives the media stream data of the network video recorder NVR, and transcodes and provides the local area network stream edge live broadcast address URL for the client to use. The media stream data is transmitted through the local area network, thereby saving public network bandwidth resources and improving the stability and smoothness of video playback.

[0087] Example 2

[0088] This embodiment is based on the aforementioned embodiment 1, and splits the edge all-in-one device into: SDM site equipment management edge device and AIoTVideo visual network recording edge device, and further introduces the media stream transmission method process of the aforementioned embodiment 1.

[0089] 3 , which is a signaling flow chart of a media stream transmission method based on an edge device provided in this embodiment.

[0090] First, in the preparation stage, step 100 also includes:

[0091] Step 100 - 1 : The SDM edge device registers device information with the SDM cloud module. The device information includes: the device identifier and the warehouse identifier of the SDM edge device.

[0092] Specifically, the device identifier of the SDM edge device can be the device name, model or device ID, etc.; the in-warehouse identifier can be the identifier of the second network (local area network), IP address, etc.; in this embodiment, it is assumed that the in-warehouse identifier is identifier 1.

[0093] Step 100-2: After receiving the registered device information, the SDM cloud module establishes a correspondence between the device identifier of the SDM edge device and the warehouse identifier, for example, a first correspondence between the device identifier ID1 and the second network IP address (ie, identifier 1).

[0094] It should be understood that a correspondence between the device identifications of other edge devices and the intranet may also be established, such as a second or third correspondence.

[0095] Step 101: The client sends a live broadcast request message to the SDM cloud module through a designated channel, which is the same as step 101 in embodiment 1.

[0096] After receiving the live broadcast request message, the SDM cloud module uses the database to query whether the SDM edge device is deployed and configured in the current warehouse (second network). If so, step 102-1 is executed. If not, the SDM edge device is not deployed, edge live broadcast is not supported, and the process ends.

[0097] The query process specifically includes: the SDM cloud module searches for a first correspondence in at least one pre-stored correspondence (established by steps 100-1 and 100-2) based on warehouse (second network) identifier 1. The first correspondence is a correspondence between identifier 1 and the device identifier of the SDM edge device. If the first correspondence exists, it is determined that the SDM edge device is deployed. If not, the SDM edge device is not deployed.

[0098] Step 102-1: If it is determined that an SDM edge device is deployed in the warehouse, the SDM cloud module sends the live broadcast request message to the SDM edge device. The request message includes: a camera module identifier, which is used to indicate that the client wants to call the live media stream data of a certain IPC.

[0099] Step 102-2, the SDM edge device sends the live broadcast request message to the AIoTVideo edge device and sends a request to create an edge stream (including the camera module identifier). At this time, the AIoTVideo edge device is ready to receive the media stream.

[0100] Step 103-1: After receiving the request to create a pull stream, the AIoTVideo edge device generates streaming service information according to the camera module identifier, the IP address of the AIoTVideo edge device, and the port of the AIoTVideo edge device for receiving videos.

[0101] Among them, the streaming media service information includes: edge live broadcast address URL, AIoTVideo edge device IP address and the port (port number), etc.

[0102] Step 103-2: The AIoTVideo edge device sends the streaming service information to the SDM edge device.
