There is a demand for live broadcast viewing in many occasions and scenes, such as scenic spot landscape promotion, restaurant dining environment promotion, and real-time viewing of scenic spot / restaurant queues. However, real-time monitoring under traditional private protocols is often limited to specific playback software, which is difficult to achieve public sharing, limiting the scope of information dissemination and utilization value. Through technical means, the real-time monitoring video of the enterprise standard protocol can be safely and efficiently converted, and slow live broadcast services can be provided to the outside world to meet the public's demand for live viewing in various scenes. Therefore, it is particularly important to be able to convert the real-time monitoring video under the enterprise standard protocol into a public slow live broadcast method.

When users watch videos, one person uses one video stream, which is directly pulled from the video source station. The bandwidth is large and is affected by the network environment, resulting in poor playback fluency such as freezes, which leads to a poor user experience.

[0004] Therefore, it is necessary to provide a live broadcast method based on a private video transmission protocol to solve the above problems. Summary of the invention

[0019] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0020] In view of the above problems, the present invention proposes a live broadcast method based on a private video transmission protocol. The live broadcast method receives a live broadcast request from a client, and initiates a stream pull request according to the terminal flag in the live broadcast request; based on the established data stream transmission channel, the protocol video data stream data is pulled from the corresponding terminal, without the need to integrate SDK, which can effectively simplify the process; the streaming media pushes the private protocol video data stream to the protocol conversion service, and can obtain the video data stream converted by the private protocol, which occupies a small bandwidth and is not affected by the network environment, thereby improving the playback fluency; the generated video stream address is sent to the distribution service as the back-source address to generate a CDN playback address, and the live broadcast content is reviewed based on the generated CDN playback address; users choose to watch the live broadcast content that has passed the content review through various client applications, which can improve the user experience. In addition, the method not only retains the real-time and accuracy of real-time monitoring, but also improves the viewing experience (i.e., user experience) through the slow live broadcast form, reduces the network bandwidth requirements, and is convenient for the public to watch in different network environments in order to meet the needs of showing the production situation to the public, enhancing transparency, and attracting public attention.

[0021] Example 1

[0022] Refer to the following Figure 1 , Figure 2 , Figure 3 , the contents of the present invention will be described in detail.

[0023] Figure 1 It is a flow chart of the steps of the live broadcast method based on the private video transmission protocol of the present invention. Figure 2 It is a schematic diagram of a framework of an application example of the live broadcast method based on a private video transmission protocol of the present invention.

[0024] like Figure 1 As shown, in step S101, a live broadcast request from a client is received, and a stream pull request is initiated according to a terminal flag in the live broadcast request.

[0025] exist Figure 2 The application examples include clients, streaming media services (such as enterprise standard protocol streaming media services), protocol conversion services, CDN distribution services, content review services, and terminals. Among them, clients generally refer to devices that can broadcast or watch live broadcasts, which can be smart phones and tablets, but are not limited to them; terminals generally refer to monitoring devices including pan-tilt cameras, gun cameras, etc.

[0026] Specifically, the client initiates a live broadcast request (eg, a slow live broadcast request) to the streaming media service. After the streaming media service passes the authentication, it initiates a stream pull request to the terminal according to the terminal flag in the request.

[0027] In this example, the streaming service is a service that plays multimedia content such as music and videos in real time over the Internet using a private video protocol transmission technology.

[0028] The private video protocol specifically includes video data packet format, video encoding format, audio encoding format, signaling message, key frame information, and group of pictures (GOP) information.

[0029] Corresponding to the private video protocol, the customized private transmission protocol includes parameters or information related to video data packet format, video encoding format, audio encoding format, signaling messages, key frame information, picture group information, etc.

[0030] The protocol conversion service converts the customized private transmission protocol video stream into a universal protocol video stream such as Real-time Streaming Protocol (RTSP), Real-time Messaging Protocol (RTMP), http+flv, etc.

[0031] It should be noted that the above is only described as an optional example and should not be understood as a limitation to the present invention.

[0032] Next, in step S102, based on the established data stream transmission channel, the protocol video data stream data is pulled from the corresponding terminal.

[0033] Specifically, a data stream transmission channel is established based on the streaming media and the terminal, which will be explained below in conjunction with the device binding process.

[0034] During the device binding process, a data stream transmission channel is established.

[0035] During the device binding process, if Figure 3 As shown, for example, Camera is used to represent the camera device, dns is used to represent the addressing server, relay is used to represent the streaming media, and esd is used to represent the message bus.

[0036] Specifically, after the camera successfully connects to the wired network, it obtains and adds the streaming media address from the DNS, connects (or links) the camera to the streaming media, but does not log in. Then, it sends a request to the streaming media (i.e. Figure 3 The streaming media forwards the GetWiredinfo request to the message bus, performs addressing, and finds the corresponding streaming media (corresponding to Figure 3 The streaming media sends binding information to the streaming media, and after the APP scans the QR code on the body, it initiates wired binding (or initiates a binding request) to the message bus, and then the streaming media forwards the binding information to the camera. In this way, the streaming media and the terminal (such as the APP) establish a data stream transmission channel.

[0037] Specifically, according to the video that the user selects to watch in the APP or mini-program application terminal, the protocol video data stream data is pulled from the corresponding terminal according to the corresponding device information of the deployment point. The protocol video data stream data includes outdoor real-time live video data, such as real-time live data of scenic spots, real-time video data of farms, real-time data of zoo animal adoption, etc.

[0038] It should be noted that the above is only described as an optional example and should not be understood as a limitation to the present invention.

[0039] Next, in step S103, the streaming media pushes the private protocol video data stream to the protocol conversion service.

[0040] Specifically, the streaming media pushes the private protocol video data stream formed by the real-time live broadcast data of scenic spots, real-time video data of farms, real-time data of zoo animal adoption, etc. to the protocol conversion service.

[0041] After receiving the private protocol video data stream, the protocol conversion service performs protocol conversion, converts it into a universal protocol video stream, and generates a video stream address, such as an address containing characters or specific symbols related to real-time live data of scenic spots, real-time video data of farms, and real-time data of zoo animal adoption. For example, https: / / cmds-test.wojiazongguan.cn:443 / live / 347563cd6b2b.live.flv? auth_key=4879209266-8fdf036bd2e85f6eedb3aefc805d1b6e-cfd1a1ab7a5573977e4d809cd2426c2c22ed3fb80e69583c21ead7d6fef938 90909bbd1d14d00e04afdd0098bcf0167ab6146bb9177f70a7e8c22e9c31bc08eb8615633f1309083bf58500717ab1efdb4ecc3f90d1bf90b8). Among them, the protocol conversion service includes private protocol conversion, and the private protocol conversion adopts a private protocol packet algorithm, specifically parsing the private protocol packet data into raw stream data according to the MediaPackage message header definition field.

[0042] First, check the packet header information: The packet header contains some flags and fields to identify the packet type, length, timestamp, and other information. By parsing the header information, you can determine whether the packet is a video packet, an audio packet, or another type of packet. Video packets usually contain video frame data, while audio packets contain audio sample data.

[0043] The two types of data packets are distinguished based on the specific flag bits or fields in the header information. The video frame data is extracted based on the data location information defined in the MediaPackage message header, such as bit7 for video, bit1 for key frame information, and bit4 for video data configuration information, including data start position, data length and other information.

[0044] Video data extraction: Extract video frame data from data packets according to the video encoding format specifications. Video frames may be key frames (I frames), predicted frames (P frames), or bidirectional predicted frames (B frames). Each video frame usually contains pixel data of the image and related encoding information.

[0045] Processing video timestamps: Video packets usually contain timestamp information for synchronizing video playback. During the unpacking process, the timestamp needs to be extracted and compared with the timestamps of other video frames to ensure the correct playback order of the video and extract the audio and video raw stream data.

[0046] Extract audio sample data: extract audio sample data from audio data packets. Audio sample data is usually a series of digital values ​​that represent the intensity and frequency of the sound.

[0047] Processing audio timestamps: Audio packets may also contain timestamp information for synchronizing audio playback. Timestamps need to be extracted during the unpacking process and synchronized with video timestamps to ensure synchronous playback of audio and video.

[0048] Finally, after obtaining the raw stream data, it is encapsulated according to the target protocol (RTSP / RTMP / HSL / FLV) protocol standard format to finally convert it into the target protocol video data stream.

[0049] The private protocol packaging algorithm is used, including encapsulating file identifiers, using characters on designated positions to indicate whether a video tag is included, and encapsulating FLV Body (including Tag Header, Tag Data, and extended bytes of timestamp, with an extended range of 24-bit to 6-bit), etc., where FLV is FlashVideo. After packaging, it is finally converted into an FLV video data stream.

[0050] Preferably, the raw stream data is format converted and video compressed while parsing the private protocol, and the raw stream data is packaged according to the target protocol (RTSP / RTMP / HSL / FLV) protocol standard to obtain universal protocol video stream data, which is then distributed through streaming media.

[0051] It should be noted that the above is only described as an optional example and should not be understood as a limitation to the present invention.

[0052] Next, in step S104, the generated video stream address is sent as a back-to-source address to a distribution service to generate a CDN playback address, and a live content review is performed based on the generated CDN playback address.

[0053] Specifically, the generated video stream address is sent as the back-to-source address to the distribution service (specifically, CDN distribution service) to generate a CDN playback address. CDN distribution service caches video content on server nodes distributed in various regions, so that when users request a video, they can directly obtain the content from the nearest CDN node, thereby reducing transmission delays and improving playback fluency.

[0054] Preferably, CDN nodes can cache videos of different resolutions and formats according to the popularity of the videos and user needs. When a user requests a video, the CDN node selects the appropriate video version and returns it to the user based on the user's network conditions and request parameters, thereby dynamically adjusting the video's clarity and format and improving the video's adaptability and compatibility. For example, the CDN node generates distribution addresses of different resolutions (720P, 1080P, 2K) and formats (HLS, FLV, RTMP, etc.) by transcoding and compressing the source video stream based on the return-to-source address, and adapts and returns the appropriate video address based on the user's network conditions and the required video format.

[0055] After the CDN playback address is generated, the content review service is notified to pull the stream to review the live content. If illegal content is found, the live source will be cut off in time.

[0056] For example, the generated video stream address https: / / cmds-test.wojiazongguan.cn:421 / live / 3**b.live.flv?auth_key=4-890-p00000008 is sent as the back-source address to the distribution service to generate a CDN playback address.

[0057] Next, in step S105, the user selects live broadcast content that has passed content review to watch through various client applications.

[0058] Based on CDN video distribution, a video stream is pulled and pushed to the AI ​​review platform. The AI ​​review platform analyzes whether the image violates the rules by taking screenshots of the video stream.

[0059] For example, users can use the client application APP on their mobile phones or tablets to select real-time live data of scenic spots that have passed content review, real-time video data of farms, and real-time data on zoo animal adoptions for viewing.

[0060] Compared with the prior art, the present invention receives a live broadcast request from a client, and initiates a stream pull request according to a terminal flag in the live broadcast request; based on the established data stream transmission channel, the protocol video data stream data is pulled from the corresponding terminal without the need to integrate an SDK, which can effectively simplify the process; the streaming media pushes the private protocol video data stream to the protocol conversion service, and can obtain the video data stream converted by the private protocol, which occupies a small amount of bandwidth and is not affected by the network environment, thereby improving the playback fluency; the generated video stream address is sent as the back-source address to the distribution service to generate a CDN playback address, and the live content is reviewed based on the generated CDN playback address; users choose to watch the live content that has passed the content review through various client applications, which can improve the user experience.

[0061] In addition, this method not only retains the real-time and accuracy of real-time monitoring, but also improves the viewing experience through slow live broadcast, reduces network bandwidth requirements, and facilitates public viewing in different network environments. It can effectively meet the needs of showing production conditions to the public, enhancing transparency and attracting public attention.

The pulling module 420 pulls the protocol video data stream data from the corresponding terminal based on the established data stream transmission channel. The push module 430 streaming media pushes the private protocol video data stream to the protocol conversion service. The distribution module 440 sends the generated video stream address as the back-source address to the distribution service to generate a CDN playback address, and performs live content review based on the generated CDN playback address. The viewing module 450 allows users to select live content that has passed content review to watch through various client applications.

After encapsulation, it is finally converted into an FLV video data stream, which specifically includes: an extended byte containing a timestamp, and the extension range is from 24 bits to 6 bits.

[0069] According to an optional implementation method, during the device binding process, a data stream transmission channel is established; the streaming media pushes the private protocol video data stream formed by the real-time live data of scenic spots, real-time video data of farms, and real-time data of zoo animal adoption to the protocol conversion service.
