[0055] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0056] The video network is a significant milestone in network development. It is a real-time network that enables real-time transmission of high-definition video, pushing many internet applications towards high-definition video and enabling high-definition face-to-face interaction.

[0057] The video network adopts real-time high-definition video switching technology, which can integrate dozens of services such as high-definition video conferencing, video surveillance, intelligent monitoring and analysis, emergency command, digital broadcasting, time-delayed television, online teaching, live broadcasting, VOD, TV mail, personalized recording (PVR), intranet (self-operated) channels, intelligent video broadcast control, information release, etc., into a single system platform, enabling high-definition video playback through televisions or computers.

[0058] One embodiment of the present invention provides a data transmission method for transmitting data to a hot standby device. The execution entity in this embodiment is a data transmission device, which is installed on a streaming media server.

[0059] Reference Figure 1 The diagram illustrates a flowchart of an embodiment of a data transmission method according to the present invention. The method may specifically include the following steps:

[0060] S101. When the backup device detects a failure in the host device, it receives a video network backup command sent by the backup device.

[0061] Specifically, this invention is applied to a dual-machine hot standby device, including a primary device and a backup device. The primary device and the backup device can communicate with each other, and both are connected to a streaming media server. Either the primary device or the backup device is also connected to a video network terminal, and the streaming media server is connected to an internet terminal. The primary device and the backup device maintain their connection via heartbeat data packets. If the backup device does not receive a heartbeat data packet from the primary device within a preset time period, it indicates a failure in the primary device. In this case, the backup device needs to be activated, switching between the primary and backup devices. The backup device sends a video network backup command to the streaming media server.

[0062] Among them, the video network terminals include at least the Aurora series video network terminals, the Qiming series video network terminals, and the decoder series video network terminals;

[0063] Internet terminals include at least mobile phone applications (APPs), computer applications (PC software), 4G image transmission devices, and drones.

[0064] S102. Starting from the current time of receiving the video network backup instruction, within a preset time period, if a video network switchover completion instruction is received from the standby device, media stream data is sent to the video network terminal. The media stream data is sent from the internet terminal to the streaming media server. The preset time period can be set as needed.

[0065] Specifically, after receiving the video network backup instruction from the backup device, the streaming media server obtains the current time of receiving the instruction and starts a timer. From this time, the host device and the backup device switch over within a preset time period. If the switchover is complete, the backup device sends a video network switchover completion instruction to the streaming media server within the preset time period. During this process, the streaming media server continues to receive media stream data from the internet terminal but does not send media stream data to the video network terminal. Upon receiving the video network switchover completion instruction, it sends the media stream data received from the internet terminal within the preset time period to the video network terminal. Throughout this process, the internet terminal and the streaming media server maintain a continuous link and remain in a business execution state, unaware that a device switchover has occurred on the video network side.

[0066] The data transmission method provided in this embodiment of the invention involves receiving a video network backup command from a backup device when the backup device detects a failure in the host device. Starting from the time the backup command is received, within a preset time period, if a video network handover completion command is received from the backup device, media stream data is sent to the video network terminal. This media stream data is sent from the internet terminal to the streaming media server. When the backup device detects a failure in the host device, it sends a video network backup command to the streaming media server. After the backup device and host device complete the handover within the preset time period, the backup device sends a video network handover completion command to the streaming media server. Then, the streaming media server sends the media stream data sent by the internet terminal to the video network terminal. During this process, the internet terminal continues to process its services and is unaware of the host device failure, thus not affecting normal business operations.

[0067] Another embodiment of the present invention further supplements the data transmission method provided in the above embodiments.

[0068] like Figure 2 The diagram illustrates a flowchart of another embodiment of the data transmission method of the present invention, which includes:

[0069] S201. When the backup device detects a failure in the host device, it receives a video network backup command sent by the backup device.

[0070] S202. Starting from the current time of receiving the video network backup instruction, within a preset time period, if a video network switchover completion instruction is received from the standby device, the Internet media stream data sent by the Internet terminal is received through the virtual terminal number.

[0071] Specifically, multiple virtual terminals are installed on the streaming media server. Each virtual terminal has a unique virtual terminal number and is bound to an internet terminal for data transmission. When the streaming media server receives a video network switching completion command, it receives the internet media stream data sent by the internet terminal bound to that virtual terminal through the virtual terminal.

[0072] S203. Parse the Internet media stream data to obtain each first video frame;

[0073] Specifically, the streaming media server parses the internet media stream data to obtain the first video frame.

[0074] S204. If the first video frame is an I-frame video frame, then convert the I-frame video frame into video network media stream data.

[0075] Specifically, the streaming media server determines the first video frame. If the first video frame is an I-frame, it sends the I-frame to the video network terminal; if the first video frame is a P-frame or a B-frame, it does not send it. The first video frame is then encapsulated using the video network protocol to obtain the video network media stream data.

[0076] S205. If the current first video frame is not an I-frame video frame, delete the current first video frame, judge the next first video frame until an I-frame video frame is found, and convert the I-frame video frame into video network media stream data.

[0077] Specifically, when the streaming media server judges the first video frame, if the detected first video frame is not an I-frame video frame, it deletes the current video frame and continues to judge the next first video frame until the next I-frame video frame is found. Then, the I-frame video frame is converted into video network media stream data.

[0078] S206. Send the video network media stream data to the video network terminal.

[0079] Specifically, after receiving the instruction that the video network switching is complete, the streaming media server simultaneously receives the video network media stream data sent by the video network terminal, and then converts the video network media stream data to obtain Internet media stream data.

[0080] S207. The media stream data sent by the video network terminal is sent to the Internet terminal bound to the virtual terminal number via the virtual terminal number.

[0081] Specifically, it includes:

[0082] Step A1: Parse the media stream data sent by the video network terminal to obtain the second video frame;

[0083] Step A2: If the second video frame is an I-frame video frame, convert the I-frame video frame into Internet media stream data;

[0084] Step A3: Send the Internet media stream data to the Internet terminal bound to the virtual terminal number via the virtual terminal number.

[0085] Specifically, after receiving the video network media stream data, the streaming media server parses the video network media stream data to obtain the second video frame; if the second video frame is an I-frame video frame, the I-frame video frame is converted into internet media stream data, and the internet media stream data is sent to the internet terminal bound to the virtual terminal number through the virtual terminal number.

[0086] S208. If no video network handover completion instruction is received from the backup device within a preset time period, a stop service instruction is sent to the Internet terminal so that the Internet terminal stops sending media stream data.

[0087] Specifically, if the streaming media server does not receive a video network switching completion instruction from the backup device within the preset time period, it means that the switch between the host device and the backup device has not been successful. The streaming media server then sends a stop service instruction to the internet terminal. After receiving the stop service instruction, the internet terminal stops sending media stream data to the streaming media server.

[0088] Figure 3 This is a schematic diagram of the structure of an embodiment of the data transmission system of the present invention, as shown below. Figure 3 As shown, this invention relates to the automatic recovery function of internet-side devices in conferencing services within the context of dual-machine hot standby functionality in video networking. Assuming that the video networking host and standby devices perfectly implement hot standby recovery functionality in the event of a failure, this embodiment focuses on how the devices on the streaming media internet side preserve the original meeting state during the video networking recovery process, without canceling the meeting or experiencing any anomalies. Once the video networking hot standby device completes its operation, the internet devices actively restore the video networking conferencing function.

[0089] In the original hot standby, if a virtual terminal goes offline, it means that the virtual terminal is unavailable. The related services will be cleared and the device will restore the services. After the hot standby is completed, the previous services will be pulled back, which also realizes the service recovery. However, in the middle, network or service abnormalities will be clearly perceived. The signaling logic will be re-run (clearing and then binding), which increases the time delay.

[0090] Video network hot standby addresses single-point-of-failure issues by deploying dual machines. However, a streaming media server, acting as an external device (or a special endpoint) in a video network conference, cannot achieve hot standby functionality through dual-machine deployment like video network servers. This special endpoint, the streaming media server, can actually contain a series of virtual terminals. Each virtual terminal can connect to multiple real devices on the streaming media side (e.g., mobile apps / PC software). This results in a structure like... Figure 3 The framework pattern.

[0091] During the dual-machine hot standby process of the video network, the virtual terminals under the streaming media server are affected in terms of network access and services. However, the APP / PC, being internet devices connected to the streaming media server, maintains a heartbeat connection with the server during the hot standby process. Under this premise, the virtual terminal can be considered a channel connecting various video network devices and internet devices, with the streaming media server acting merely as a gateway. During the dual-machine hot standby process, this channel is temporarily interrupted, but for the internet devices, the transition from primary to backup for the video network device is indistinguishable. Therefore, the original state relationships and business operations can be maintained.

[0092] Figure 4 This is a schematic diagram of another embodiment of the data transmission system of the present invention; Figure 5 This is a schematic diagram of the structure of another embodiment of the data transmission system of the present invention. Figure 4 and Figure 5 These represent different operating states of the equipment. Figure 4 This indicates that the video network host is active. Figure 5 This indicates that the backup device for the video network is active. Figure 4 In this context, under normal circumstances, both the video network terminal and the virtual terminal within the streaming media exchange interact with the video network host. Solid black lines represent active video network interactions, while dashed lines represent active internet interactions. Correspondingly, the link channels for the streaming media side's device resources consist of both solid and dashed lines. Video network terminals are represented by solid lines.

[0093] exist Figure 5 During the process, after the dual-machine hot standby is completed, the standby machine in the video network becomes active and turns into a solid line. Therefore, the channel is unobstructed before and after the dual-machine hot standby. Figure 4 and Figure 5 In this context, the connection between the streaming media server and the internet terminal has remained unchanged.

[0094] This invention addresses how to quickly restore service to the corresponding streaming media devices during the interval T between the moment of switching when the video network host loses contact and the backup host has not yet established contact. During time interval T, the streaming media devices are unaware of this, as they are not directly connected to the video network. Only the streaming media server is aware that its virtual terminal has gone offline. During this time interval T, the streaming media devices continue to transmit media streams (uplink) while waiting for the virtual terminal to send media streams (downlink). When the virtual terminal transmits data, it checks if the uplink is an I-frame. If not, it filters it until the nearest I-frame is received, marked as an IDR, and sent to the virtual terminal. Simultaneously, it checks the downlink media stream to determine if it is the first I-frame (IDR). If not, it filters it; if so, it is transmitted to the corresponding streaming media device.

[0095] In a video network conference, a series of internet devices are brought into the conference. The streaming media server binds these internet devices to their virtual devices, establishing a data transmission channel. Uplink and downlink transmissions occur during the conference. If a virtual terminal goes offline during a dual-machine hot standby, the transmission channel becomes blocked. At this time, each internet device maintains its conference mode, recording the current time and status changes. It continuously sends its own data media stream to the offline bound virtual terminal. Simultaneously, it continuously receives media streams from the virtual terminal, even though no media data is currently being sent. Superficially, the internet devices appear to be in a static frame state (the image is frozen in one frame, without change). When the dual-machine hot standby is complete, the virtual device reconnects to the network under the streaming media server, and the video network resumes its original conference services: ① On the streaming media side, signaling control logic interaction is omitted, and media stream interaction is performed directly. ② At the moment the virtual terminal connects to the network, it checks whether the media stream sent from the streaming media device to the virtual terminal is an I-frame. If not, it filters it until the nearest I-frame is found, which is then marked as an IDR (I-frame identifier) ​​and sent to the virtual terminal. Simultaneously, the media stream from the virtual terminal is detected to determine if it is the first I-frame (IDR). If not, it is filtered; if so, it is transmitted to the corresponding streaming media device. This ensures the fastest decoder reset and the fastest picture rendering. ③ Anomaly Handling: A set time is set when the connection drops, and the duration of the disconnection is recorded. If the disconnection exceeds a certain time, it indicates that the dual-machine hot standby has failed and the service cannot be restored. In this case, the streaming media no longer needs to maintain the current service state, the binding relationship between the virtual terminal and the device is deleted, and the virtual terminal and the device are restored to idle state.

[0096] Figure 6 This is a flowchart illustrating the steps of another embodiment of the data transmission method of the present invention, as follows: Figure 6 As shown, the data transmission method includes:

[0097] S601. Start the streaming media server.

[0098] S602, Virtual terminal access: Internet terminal and streaming media server establish heartbeat, and can receive video network signaling to conduct business;

[0099] S603, the streaming media server receives video network signaling and pulls in APP / PC members.

[0100] S604 establishes a binding relationship between the APP / PC and the virtual terminal, and sends the received video network media stream to the corresponding APP / PC, or sends the Internet media stream sent by the APP / PC to the video network.

[0101] S605, the streaming media server received the video network backup signaling.

[0102] S606, the streaming media server records the current moment, starts a timer, marks the current state as hot standby, and maintains the status and services of the Internet-side devices.

[0103] S607. If the streaming media server receives the video network completion instruction within the time range set by the timer.

[0104] S608, the streaming media server determines whether the timer is still on, shuts it down, detects the uplink and downlink media streams, filters I-frames, and marks the hot standby status as complete.

[0105] S609. If the streaming media server does not receive the video network completion instruction within the time range set by the timer.

[0106] S610: Determine if the timer is still on, then turn it off, unbind it, stop the service, and close the uplink and downlink channels.

[0107] The embodiments of the present invention can solve the problem of how to quickly restore conference services on Internet devices after a single point of failure in video networking services. Once solved, it will greatly improve the user experience and enhance user stickiness.

[0109] The data transmission method provided in this embodiment of the invention involves receiving a video network backup command from a backup device when the backup device detects a failure in the host device. Starting from the time the backup command is received, within a preset time period, if a video network handover completion command is received from the backup device, media stream data is sent to the video network terminal. This media stream data is sent from the internet terminal to the streaming media server. When the backup device detects a failure in the host device, it sends a video network backup command to the streaming media server. After the backup device and host device complete the handover within the preset time period, the backup device sends a video network handover completion command to the streaming media server. Then, the streaming media server sends the media stream data sent by the internet terminal to the video network terminal. During this process, the internet terminal continues to process its services and is unaware of the host device failure, thus not affecting normal business operations.
