Description

Technical Field

[0001] This invention relates to the field of video transmission, and in particular to a media streaming method, apparatus, and electronic device based on edge devices. Background Technology

[0002] During the packing and handling of goods in the logistics warehouse, video cameras or camcorders will record the operations of the staff on the workbench. This video recording can be used as evidence to determine responsibility if the package is damaged or otherwise abnormal after the user receives it, proving that no damage was caused to the goods during the packing or handling process.

[0003] To ensure the reliability of video recording, a real-time video preview window is provided on the operating system of the monitoring terminal page, allowing operators to monitor whether video recording is running normally. When operators find that the equipment used for packaging is malfunctioning, they can promptly repair or replace it with other recordable equipment.

[0004] Because all operations during real-time video recording need to be continuously displayed on the screen, existing solutions connect recorders or cameras to the public network via standard protocols. If the quantity of items being packaged is large, numerous workstations will need to record and play video simultaneously, significantly consuming network bandwidth resources within the warehouse. Furthermore, the public network transmission of video media streams can lead to instability, affecting monitoring effectiveness. Summary of the Invention

[0062] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0063] The technical solution provided in this invention is applied to a media streaming live streaming system, or a media streaming system for live logistics packaging process.

[0064] like Figure 1 As shown, the system includes: a Station Device Management (SDM) cloud module, an AIoT Video cloud module, at least one client, an SDM edge device, an AIoT Video edge device, at least one Network Video Recorder (NVR), and at least one camera module, such as a camera.

[0065] AIoT stands for AI+IoT, which refers to the integration of artificial intelligence technology and the Internet of Things in practical applications. AIoTVideo video network recording cloud module refers to an AIoT cloud device with video recording function; similarly, AIoTVideo video network recording edge device refers to an AIoT edge device with video recording function.

[0066] 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., and this embodiment does not limit this.

[0067] 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 channel 2 to connect to camera module 2; similarly, NVR2 uses channel 3 to connect to camera module 3 and channel 4 to connect to camera module 4, and so on.

[0068] The camera module includes, but is not limited to, a camera, and may also be other devices with photo / video recording functions.

[0069] The functions of each module are as follows:

[0070] The SDM cloud module is responsible for managing the metadata of video devices and providing access points for business systems to use video devices, such as viewing video device status, viewing live video, viewing recordings, and downloading recordings.

[0071] 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.

[0072] The AIoTVideo cloud module (AIoTVideo_Cloud) is responsible for connecting the video recorder devices, managing device status, and exchanging control commands.

[0073] The AIoTVideo edge device (AIoTVideo_Edge) is responsible for receiving and transcoding the stream from the edge-side recorder.

[0074] A network video recorder (NVR) is responsible for connecting camera devices, storing recordings, and connecting to the cloud to provide video preview and playback.

[0075] Furthermore, the aforementioned devices are wirelessly connected. Specifically, the SDM cloud module and the AIoTVideo cloud module communicate using HTTP (Hypertext Transfer Protocol); at least one NVR communicates with the AIoTVideo cloud module using the Socket protocol; at least one NVR communicates with the AIoTVideo edge device using the Socket protocol; the SDM edge device communicates with the SDM cloud module using the Socket protocol; and the SDM edge device communicates with the AIoTVideo edge device using the HTTP protocol.

[0076] Optionally, the SDM edge device and the AIoTVideo edge device can be located on two separate 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".

[0077] Generally, NVRs (Network Video Recorders) use the GB28181 protocol (a national standard in the video surveillance field) to establish a connection with cloud signaling services. When playing video in real time, the NVR transmits video data to the cloud via the public network, and then the user retrieves 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 being played, it will consume a lot of public network bandwidth resources, which may lead to network congestion, transmission delays, and unstable real-time video playback.

[0078] To address the aforementioned technical problems, this application provides a media streaming method based on edge devices. This method pre-divides the various devices into two networks: a first network and a second network. 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. Furthermore, the first and second networks may include more or fewer other modules / devices; this embodiment does not impose any limitations on this.

[0079] In addition, at least one client can be set in either the first network or 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 being located in the second network as an example.

[0080] Optionally, the first network may also 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.

[0081] In this embodiment, by setting up SDM edge devices and SDM edge streaming media services (AIoTVideo cloud modules) in the warehouse, when playing real-time video in the warehouse, the media stream data is transmitted through the private network using the SDM edge devices. When playing on the public network, the video is pulled through the public network using cloud live streaming, thereby saving public network bandwidth resources.

[0082] Example 1

[0083] See Figure 2 This embodiment provides a media streaming method based on an edge device, which includes the following steps:

[0084] Step 100: Preparation phase, each NVR sends registration information to the AIoTVideo cloud module to register at least one NVR on the cloud network.

[0085] One implementation involves each NVR registering its camera module information on the AIoTVideo cloud module using the GB28181 protocol. Further, this specifically includes:

[0086] The NVR sends channel information to the AIoTVideo cloud module. This channel information includes a channel identifier and a national standard ID. The channel refers to the communication link between each camera module and its connected NVR. The channel can represent an IPC (Internet Protocol Camera), a network-protocol-based camera also known as a network camera or network surveillance camera. It uses a network connection (such as Ethernet) to transmit video and audio data and communicates with other devices over the network.

[0087] Additionally, a national standard ID is used to identify each channel, such as national standard ID1, national standard ID2, etc. Optionally, the national standard ID can be a string composed of numbers, letters, and symbols.

[0088] The preparation phase also includes: after receiving the channel information, the AIoTVideo cloud module generates video device information and sends it to the SDM cloud module. Upon receiving the video device information, the SDM cloud module saves the video device metadata, i.e., the video device information itself.

[0089] The video device information includes at least one parent-child relationship. For example, if two camera modules are connected to NVR1, and the corresponding device identifiers are IPC1 and IPC2, then establishing a parent-child relationship would be: NVR1 - IPC1 & IPC2. Similarly, each other NVR and its connected camera module IPC can be established, and this information can be stored on the SDM cloud module.

[0090] The method provided in this embodiment will be described in detail below.

[0091] like Figure 2 As shown, the media stream transmission method includes:

[0092] Step 101: The client sends an edge live streaming request message to the SDM cloud module via the specified channel; correspondingly, the SDM cloud module receives the live streaming request message from the client.

[0093] The live streaming request message includes the identifier of the camera module requesting the live stream, such as IPC1 or channel 1, indicating a request to obtain the live media stream from IPC1, or a request to obtain the live media stream from IPC1 connected to channel 1.

[0094] The client is a client located on the second network. The client can be a terminal device, including but not limited to various personal computers (PCs), laptops, smartphones, tablets, etc.

[0095] Step 102: The SDM cloud module sends the live streaming request message to the edge all-in-one machine to request media streams from at least one NVR.

[0096] Step 103: After receiving the live streaming request message sent from the SDM cloud module, the edge all-in-one machine generates media stream service information based on the camera module identifier.

[0097] The media stream service information includes: the edge live streaming address URL (Uniform Resource Locator), the IP address of the edge appliance, and the port used by the edge appliance to receive the media stream. The IP address and port number of the edge appliance can be pre-set and stored on the edge appliance for use when generating the media stream service information.

[0098] Step 104: The edge appliance sends the media stream service information to the SDM cloud module.

[0099] 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, edge all-in-one machine IP address and port, etc.

[0100] 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.

[0101] Step 106: The AIoTVideo cloud module receives the media stream service information and the camera module identifier, and requests the media stream from the target NVR corresponding to the camera module identifier based on this information.

[0102] Specifically, the AIoTVideo cloud module identifies the target NVR based on the camera module identifier, and then sends an invite request to the target NVR to request media streams 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 streams.

[0103] Furthermore, one implementation method for the AIoTVideo cloud module to determine the target NVR is as follows: the AIoTVideo cloud module searches for the NVR associated with the current IPC1 based on the camera module identifier, such as IPC1, in at least one pre-stored parent-child relationship (video device information stored in the aforementioned preparation stage), and selects it as the target NVR. In this example, assuming that IPC1 is associated with NVR1, i.e., a parent-child relationship exists, then the target NVR is NVR1.

[0104] Step 107: When IPC1 is turned on, it captures video of the surrounding environment, records and generates a media stream, and pushes the media stream to the edge all-in-one machine through the target NVR.

[0105] Correspondingly, the edge all-in-one machine receives and stores the media stream pushed by the target NVR in real time.

[0106] Step 108: Based on the invite request in Step 106 above, the target NVR returns a response to the AIoTVideo cloud module. This response can indicate a successful request or a failed request.

[0107] Correspondingly, the AIoTVideo cloud module receives the response and makes a judgment. If the AIoTVideo cloud module receives a message indicating that the request was successful, such as receiving a response, it means that the invitation was successful and proceeds to step 109.

[0108] If the AIoTVideo cloud module does not receive a response, it indicates that the request was unsuccessful, the process ends, and the request is terminated. Furthermore, the success or failure of the request can be indicated and determined by fields or identifier codes in the response.

[0109] Step 109: The AIoTVideo cloud module sends the successful request message (i.e., the response) from step 108 to the SDM cloud module.

[0110] Step 110: After receiving the successful request message, the SDM cloud module sends the edge live streaming address URL to the client. Optionally, the URL is also called the edge live streaming address URL.

[0111] Step 111: After receiving the edge live streaming address URL, the client requests the media stream from the edge all-in-one machine through the edge live streaming address URL.

[0112] Step 112: The edge appliance sends the media stream received in step 107 above to the client according to the URL.

[0113] The client receives the media stream and plays it in real time using its playback software, thus enabling live streaming of the media stream on the client.

[0114] The method provided in this embodiment involves deploying edge devices on an edge all-in-one machine in a second network (local area network) and establishing a long connection with at least one cloud module in the first network, such as an SDM cloud module and an AIoTVideo cloud module. When a client needs to request edge live streaming on the local area network, the edge all-in-one machine receives media streams recorded by camera modules and receives media stream data from a network video recorder (NVR). The edge all-in-one machine then transcodes and provides a local area network pull-stream edge live streaming address URL for the client to use. By transmitting media stream data through the local area network, public network bandwidth resources are saved, and the stability and smoothness of video playback are improved.

[0115] Example 2

[0116] This embodiment is based on the aforementioned Embodiment 1, and the edge integrated machine is split into: SDM site equipment management edge device and AIoTVideo video network recording edge device, and the media stream transmission method flow of Embodiment 1 is further introduced.

[0117] See Figure 3 The diagram shown is a signaling flowchart of a media stream transmission method based on an edge device provided in this embodiment.

[0118] First, in the preparation phase, step 100 also includes:

[0119] Step 100-1: The SDM edge device registers its device information with the SDM cloud module. The device information includes the device identifier and warehouse identifier of the SDM edge device.

[0120] Specifically, the device identifier of the SDM edge device can be the device name, model, or device ID, etc.; the warehouse identifier can be the identifier of the second network (local area network), IP address, etc.; in this embodiment, the warehouse identifier is assumed to be identifier 1.

[0121] 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 identifier within the warehouse. For example, it establishes a first correspondence between device identifier ID1 and the second network IP address (i.e., identifier 1).

[0122] It should be understood that a mapping relationship can also be established between the device identifiers of other edge devices and the internal network, such as a second or third mapping relationship.

[0123] Step 101: The client sends a live streaming request message to the SDM cloud module through the specified channel, which is the same as step 101 in Example 1.

[0124] After receiving the live streaming request message, the SDM cloud module queries the database to see if an SDM edge device is deployed and configured in the current warehouse (second network). If yes, it proceeds to step 102-1. If no, no SDM edge device is deployed, edge live streaming is not supported, and the process ends.

[0125] 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 above) based on the warehouse (second network) identifier 1. The first correspondence is the 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 has been deployed. If it does not exist, the SDM edge device has not been deployed.

[0126] 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: camera module identifier, which is used to indicate to the client that it wants to call the live media stream data of a certain IPC.

[0127] Step 102-2: The SDM edge device sends the live streaming request message to the AIoTVideo edge device and sends a request to create an edge streaming stream (including the camera module identifier). At this time, the AIoTVideo edge device is ready to receive the media stream.

[0128] Step 103-1: After receiving the request to create a streaming service, the AIoTVideo edge device generates streaming media service information based on the camera module identifier, the IP address of the AIoTVideo edge device, and the port used by the AIoTVideo edge device to receive video.

[0129] The streaming media service information includes: edge live address URL, IP address of AIoTVideo edge device, and port (port number), etc.

[0130] Step 103-2: The AIoTVideo edge device sends the streaming media service information to the SDM edge device.

[0131] Step 104: After receiving the streaming media service information, the SDM edge device forwards the streaming media service information to the SDM cloud module.

[0132] After receiving the streaming media service information, the SDM cloud module sends the streaming media service information and the camera module identifier to the AIoTVideo cloud module to invite the AIoTVideo cloud module to pull the stream from the edge. Upon receiving the streaming media service information, the AIoTVideo cloud module determines the target NVR based on the camera module identifier and sends an invite request to the target NVR. This invite request includes the IP address of the AIoTVideo edge device and the aforementioned video port. The AIoTVideo edge device also receives the media stream sent by the target NVR, and when it receives an edge live streaming address URL from a client, it sends the media stream to the client.

[0133] The specific implementation process is the same as steps 105 to 112 in Embodiment 1, and can be found in the description of Embodiment 1 above. This embodiment will not repeat the details.

[0134] In this embodiment, the edge all-in-one machine's functionality is divided into two modules: an SDM edge device and an AIoTVideo edge device. The SDM edge device (or SDM 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. The AIoTVideo edge device is responsible for receiving and transcoding the NVR stream from the edge side. An edge gateway is provided and privately deployed at the user's site. The system can be configured to use edge live streaming from a designated repository. When a live stream is requested on-site, the edge gateway receives the media stream data from the recorder, transcodes it, and provides a LAN pull address for the user. Video data is transmitted via the LAN, saving public network bandwidth and improving the stability and smoothness of video playback.
