[0016] Optionally, in response to a user-triggered video playback request, the video stream data stored in the edge computing node is played in real time, including:

[0017] The edge computing node initiates a streaming service and, in response to a user-triggered video playback request, performs format conversion on the video stream data stored in the edge computing node.

[0018] The converted video stream data is played in real time through the edge computing node.

[0019] Optionally, after encoding and uploading the acquired video stream data to the network video recorder through at least one monitoring channel, the method further includes:

[0020] A heartbeat detection is performed on the network video recorder, and the operating status of the network video recorder is determined based on the detection results.

[0021] Based on the judgment result, the operating status of the network video recorder is reported to the server.

[0022] Optionally, before encoding and uploading the acquired video stream data to the network video recorder via at least one monitoring channel, the following steps are also included:

[0023] By developing a node deployment system, the attribute information corresponding to the edge computing nodes is configured, and the configured edge computing nodes are deployed within a preset range around the user terminal location.

[0024] According to another aspect of the present invention, a video data transmission apparatus is provided, the apparatus comprising:

[0025] The encoding and uploading module is used to encode and upload the collected video stream data to the network video recorder through at least one monitoring channel, and the network video recorder stores the encoded video stream data.

[0026] The protocol determination module is used to determine the real-time streaming protocol matched by the network video recorder through pre-deployed edge computing nodes, and construct the video stream protocol address corresponding to the network video recorder based on the streaming protocol.

[0043] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0044] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0045] Figure 1a This is a flowchart illustrating a video data transmission method provided in an embodiment of the present invention. This embodiment is applicable to the transmission, buffering, and playback of video stream data acquired by a video acquisition device. The method can be executed by a video data transmission device, which can be implemented in hardware and / or software and configured in an electronic device, such as... Figure 1a As shown, the method includes:

[0046] Step 110: Encode and upload the collected video stream data to a network video recorder (NVR) through at least one monitoring channel, and store the encoded video stream data through the network video recorder.

[0047] In this embodiment, specifically, Figure 1b This can be a schematic diagram of the system architecture applicable to the video data transmission method, such as... Figure 1b As shown, the collected video stream data can be encoded and uploaded to the network video recorder through multiple monitoring channels (such as Channel_1, Channel_2, Channel_3, Channel_4, etc.), and then the network video recorder stores the encoded video stream data.

[0048] Step 120: Determine the real-time streaming protocol matched by the network video recorder through pre-deployed edge computing nodes, and construct the video stream protocol address corresponding to the network video recorder based on the streaming protocol.

[0049] In this embodiment, as Figure 1b As shown, an edge computing node can include a device discovery system, an RTSP caching and persistence system, and a real-time streaming media transmission system. The data transfer process between these three systems also includes two processing steps: a device protocol parser and a video codec. In addition, Figure 1b The architecture diagram shown also includes the computing node deployment system.

[0050] The computing node deployment system is used to deploy a series of edge computing nodes at the network edge between the server and the user terminal. These nodes are distributed close to the user to provide low-latency data transmission and real-time streaming media services.

[0051] The device discovery system is used to discover network video recorders that meet the device protocol requirements. Once a network video recorder is discovered, a local device discovery notification is sent.

[0052] The device protocol parser is used to adapt different RTSP protocols according to the different types of network video recorders (such as brand information or product models), and to construct the video stream protocol address corresponding to the network video recorder based on the adapted protocol.

[0053] The video codec is used to encode or decode the main or sub-stream data of a network video recorder according to different protocols adapted to the network video recorder. These protocols include Advanced Video Coding (H.264), High Efficiency Video Coding (H.265), Advanced Audio Coding (AAC), OPUS audio coding, and G.711 audio coding.

[0054] Step 130: Through the edge computing node, retrieve video stream data from the network video recorder according to the video stream protocol address, and decode and store the video stream data.

[0055] In this embodiment, optionally, such as Figure 1b The architecture diagram shown illustrates that the RTSP caching and persistence system in the edge computing node can pull video stream data from the network video recorder according to the video stream protocol address, decode the video stream data with the help of a video codec, and finally perform local persistent storage of the decoded video stream data.

[0056] In one specific embodiment, the RTSP caching and persistence system can use the open-source audio and video processing tool ffmpeg to locally persist the decoded video stream data. The video stream data can be stored in MP4 format on a SATA HDD. The implementation code related to the persistent storage is as follows:

[0057] ffmpeg -i rtsp: / / 10.1.188.64:554 / live / sample -r 1 / 60 -c copy -map 0 -f segment -segment_time 120 -segment_format mp4.

[0058] Step 140: In response to a user-triggered video playback request, play the video stream data stored in the edge computing node in real time.

[0059] In this embodiment, optionally, such as Figure 1b As shown, if a user triggers a video playback request through a terminal or edge computing node, the MP4 format video stream data can be converted into RTSP protocol video stream data through the real-time streaming media transmission system in the edge computing node, and then played in real time. Specifically, the format conversion can be performed using ffmpeg commands; the relevant code is as follows:

[0060] ffmpeg -re -i $input_file -vcodec h264 -acodec aac -f rtsp rtsp: / / 127.0.0.1:$output_port / live.sdp.

[0061] In this embodiment, since the edge computing node has intelligent caching and prefetching functions, by actively caching the video stream data related to user needs using the edge computing node, and playing the video stream data using a real-time streaming media transmission system, a low-latency and high-bandwidth real-time streaming media transmission experience can be provided to users, improving the transmission efficiency of video stream data and reducing transmission latency.

[0062] The technical solution provided by this invention encodes and uploads collected video stream data to a network video recorder through at least one monitoring channel. The network video recorder stores the encoded video stream data. A pre-deployed edge computing node determines the real-time streaming protocol matched to the network video recorder and constructs a video stream protocol address corresponding to the network video recorder based on the protocol. The edge computing node retrieves video stream data from the network video recorder according to the video stream protocol address, decodes and stores the video stream data, and responds to a user-triggered video playback request by playing the video stream data stored in the edge computing node in real time. This technical approach can reduce the transmission latency of video stream data, improve transmission efficiency, and enhance the user's viewing experience.

[0063] Figure 2 A flowchart of another video data transmission method provided in an embodiment of the present invention is shown below. Figure 2 As shown, the method includes:

[0064] Step 210: Deploy the system through the development node, configure the attribute information corresponding to the edge computing node, and deploy the configured edge computing node within a preset range around the user terminal location.

[0065] In this embodiment, the development node deployment system is an automated tool or platform used to efficiently and consistently deploy software applications, services, or components to multiple physical / virtual nodes (servers, containers, etc.) and manage inter-node collaboration and resource scheduling. Specifically, the edge computing nodes can be deployed using the Android 12 system, Kotlin language, and MVVM (Model-View-ViewModel) architecture.

[0066] The attribute information of the edge computing node pair may include developer mode information and network configuration information (such as Transmission Control Protocol / Internet Protocol (TCP / IP), Domain Name System (DNS) server, gateway configuration, etc.). The edge computing node is uniquely identified by its local / system / proc device number, and its configuration information is uniformly managed through a central server.

[0067] In this step, specifically, the development node deployment system can deploy the configured edge computing nodes in locations close to the user terminal.

[0068] Step 220: Encode and upload the collected video stream data to the network video recorder through at least one monitoring channel, and store the encoded video stream data through the network video recorder.

[0069] In this step, optionally, the monitoring channel can use the TCP protocol or the User Datagram Protocol (UDP) to upload the encoded video stream data to the network video recorder.

[0070] In one embodiment of this example, after the collected video stream data is encoded and uploaded to the network video recorder through at least one monitoring channel, the method further includes: performing heartbeat detection on the network video recorder, determining whether the network video recorder is operating normally based on the detection result, and reporting the operating status of the network video recorder to the server based on the determination result.

[0071] In one specific embodiment, heartbeat detection is a "liveness confirmation" mechanism between the network video recorder and the monitoring platform. The network video recorder needs to periodically send heartbeat signals (small data packets) to the platform to prove that it is online. If the platform does not receive a signal within a set time, it determines that the network video recorder has malfunctioned and triggers an alarm or switches to a backup device.

[0072] The advantage of this setup is that it ensures the stability of the network video recorder's data connection and allows for a rapid response to operational failures of the network video recorder.

[0073] Step 230: Poll the Internet Protocol (IP) address and port number corresponding to each monitoring channel through the edge computing node.

[0074] Step 240: Using the edge computing node, identify network video recorders that meet the preset protocol requirements based on the polling results, and determine the real-time streaming protocol matched by the network video recorder based on the feature information of the network video recorder.

[0075] In this embodiment, specifically, such as Figure 1b As shown, the device discovery system in the edge computing node can poll the open status of ports 554 / 555 for IP addresses within the same gateway and network segment, and discover network video recorders that meet the preset protocol requirements by IP address and port number.

[0076] In this step, after the device discovery system identifies a network video recorder that meets the preset protocol requirements, it can determine the real-time streaming protocol matched by the network video recorder based on the network video recorder's characteristic information (such as manufacturer identification, manufacturer protocol information, etc.).

[0077] Step 250: Using the edge computing node, construct the video stream protocol address corresponding to the network video recorder according to the transmission protocol, pull video stream data from the network video recorder according to the video stream protocol address, and decode and store the video stream data.

[0078] In this step, the device discovery system assembles the video stream protocol address according to the transmission protocol, and then the RTSP caching and persistence system pulls the video stream data from the network video recorder according to the video stream protocol address, decodes the video stream data, and performs local persistent storage of the decoded video stream data.

[0079] In one embodiment of this example, retrieving video stream data from a network video recorder according to the video stream protocol address and decoding and storing the video stream data includes: retrieving video stream data from the network video recorder according to the video stream protocol address and decoding the video stream data according to the real-time streaming protocol matched by the network video recorder; determining whether the video stream data has been successfully decoded, and if so, persistently storing the decoded video stream data locally.

[0080] Optionally, if the video stream data decoding fails, a decoding failure error message can be generated, or the video stream data can be re-decoded according to a preset fault tolerance mechanism. This embodiment does not impose any restrictions on this.

[0081] Step 260: Start the streaming service through the edge computing node, and in response to the video playback request triggered by the user, perform format conversion on the video stream data stored in the edge computing node.

[0082] In this embodiment, taking Android as an example, the video stream data retrieval, decoding, and streaming operations can be implemented using ffmpeg commands in conjunction with the libstreaming and libRtmp libraries. The persistent storage of the video stream data can be achieved using MediaRecorder.

[0083] Step 270: Play the converted video stream data in real time through the edge computing node.

[0084] In this embodiment, optionally, the streaming service can be started through the RTSP caching and persistence system. After the user triggers a video playback request, the real-time streaming media transmission system can play the streaming media in real time through the RTSP caching and persistence system. This operation can be implemented through Google Media 3.

[0085] The technical solution provided by this invention configures the attribute information of edge computing nodes through a node deployment system, deploys the configured edge computing nodes within a preset range around the user terminal location, encodes and uploads the collected video stream data to a network video recorder through a monitoring channel, stores the encoded video stream data through the network video recorder, polls the Internet Protocol address and port number of the monitoring channel through the edge computing nodes to identify network video recorders that meet the preset protocol requirements, constructs the video stream protocol address of the network video recorder, pulls video stream data from the network video recorder, decodes and stores the video stream data, and performs format conversion on the video stream data stored in the edge computing nodes in response to the user's video playback request, and plays the converted video stream data in real time. This technical approach enables video stream data to be transmitted to the user terminal more quickly, reduces hops in the transmission link, and lowers transmission latency. Furthermore, the intelligent caching and prefetching technology deployed on the edge computing nodes can cache and prefetch video stream data in advance according to user needs, reducing bandwidth requirements on the cloud server, improving bandwidth utilization, and enhancing the user's viewing experience of the video stream data.

[0090] The video playback module 340 is used to respond to a video playback request triggered by a user and play the video stream data stored in the edge computing node in real time.
