[0032] The present application is described below in conjunction with embodiments:

[0033] According to one aspect of an embodiment of the present application, a method for transmitting video data is provided. Optionally, in this embodiment, the method for transmitting video data can be applied to Figure 1 In the hardware environment composed of the server 101 and the terminal device 103 shown in FIG. Figure 1As shown, the server 101 is connected to the terminal 103 via a network, and can be used to provide services for the terminal device or an application 107 installed on the terminal device. The application can be a video application, an instant messaging application, a browser application, an educational application, a game application, etc. A database 105 may be set up on the server or independently of the server to provide data storage services for the server 101, for example, a game data storage server. The above-mentioned network may include, but is not limited to, a wired network and a wireless network, wherein the wired network includes, a local area network, a metropolitan area network and a wide area network; the wireless network includes, Bluetooth, WIFI and other networks that implement wireless communication; the terminal device 103 may be a terminal configured with an application, and may include, but is not limited to, at least one of the following: a mobile phone (such as an Android phone, an iOS phone, etc.), a laptop computer, a tablet computer, a PDA, a MID (Mobile Internet Devices), a PAD, a desktop computer, a smart TV, an intelligent voice interaction device, a smart home appliance, a vehicle-mounted terminal, an aircraft, a virtual reality (VR) terminal, an augmented reality (AR) terminal, a mixed reality (MR) terminal and other computer devices; the above-mentioned server may be a single server, a server cluster consisting of multiple servers, or a cloud server.

[0034] Combination Figure 1 As shown, the above-mentioned video data transmission method can be executed by an electronic device, which can be a terminal device or a server. The above-mentioned video data transmission method can be implemented by the terminal device or the server respectively, or by the terminal device and the server together.

[0035] The above is only an example and is not specifically limited in this embodiment.

[0036] Optionally, as an optional implementation, as Figure 2 As shown, the above-mentioned video data transmission method includes:

[0037] S202, dividing each video frame in a group of video frames acquired by the image acquisition device into a group of data packets, wherein each data packet includes a sequence identifier, and the sequence identifier is used to indicate the video frame to which the data packet belongs and the sending order;

[0038] Optionally, in an embodiment of the present application, the above-mentioned image acquisition device may include but is not limited to smart phones, computers, notebooks, smart wearable devices, cameras, etc. The above-mentioned data message can be understood as a data packet containing video frame information that can be transmitted in the network, and the above-mentioned sequence identifier refers to a number or code used to identify the position of the data message in the video frame sequence.

[0039] It should be noted that the above-mentioned sequence identifier can be used to determine the internal order of the data packet in a group of video frames, and which data frame the data packet belongs to. For example, the order of the data packet is expressed as 1.3, indicating that the data packet is the third data packet in the first video frame in the above-mentioned group of video frames.

[0040] For example, Figure 3 FIG. 1 is a schematic diagram of an optional method for transmitting video data according to an embodiment of the present application. The above set of video frames may include but are not limited to being transmitted via a WiFi network. The schematic diagram of Wi-Fi transmission of streaming media data is as follows: Figure 3 shown.

[0041] S204, increasing the transmission power, reducing the receiving power, and sending a first group of data packets corresponding to the first video frame to the monitoring platform in sequence according to the sequence identifier, wherein the first group of data packets includes a first data packet indicated by the sequence identifier as being sent last in the first group of data packets;

[0042] S206, in response to the first data message being sent, increasing the receiving power and reducing the sending power;

[0043] Optionally, in an embodiment of the present application, the above-mentioned sending power can be understood as the power level used by the image acquisition device when sending the first video frame, which is usually measured in milliwatts (mW) or decibel milliwatts (dBm). The above-mentioned receiving power refers to the power level used by the monitoring platform when receiving the first video frame. The above-mentioned monitoring platform can be understood as a system or service that receives and processes these data messages, which can be a server, a cloud service or a local monitoring system.

[0044] It should be noted that Figure 4 is a schematic diagram of another optional video data transmission method according to an embodiment of the present application, such as Figure 4 As shown, when using a WiFi network to transmit data messages, its receiving power and transmitting power can both represent the power of the WiFi network card, and can also include the forwarding power of the WiFi router, etc. This application does not impose any limitation on this.

[0045] For example, the signal strength is increased at the image acquisition device to ensure that data packets can be transmitted more efficiently, while the power may be reduced at the monitoring platform to save energy or reduce interference. The sequence identifier is used to ensure that the data packets are sent to the monitoring platform in the correct order.

[0046] For example, the image acquisition device has a video frame to send, and its corresponding first set of data messages is as follows:

[0047] Data message 1: contains the header information of the video frame and a part of the video data, and has a sequence identifier 1, indicating that this is the first data message in the group;

[0048] Data message 2: contains another part of the video frame data and has a sequence identifier 2, indicating that this is the second data message in the group;

[0049] The first data packet: contains the last part of the video frame data and carries a sequence identifier 3, indicating that this is the last one of the group of data packets.

[0050] It should be noted that the above-mentioned sequence identifier is not limited to the use of digital representation, but can also be characters, etc. For example, in the above example: data message 1 carries sequence identifier a, indicating that this is the first data message in the group; data message 2 carries sequence identifier b, indicating that this is the second data message in the group; the first data message carries sequence identifier c, indicating that this is the last data message in the group.

[0051] Further, after the first data message is successfully sent, the receiving power is increased to receive a response or confirmation from the monitoring platform, and at the same time, the sending power is reduced to save energy or prepare to receive data.

[0052] Specifically, it includes but is not limited to the case where the image acquisition device determines that only the last data packet (the first data packet) in the current video frame has not been sent. At this time, by setting the sequence identifier of the first data packet and sending it to the monitoring platform, the receiving power of the monitoring platform can be increased accordingly, and the sending power of the image acquisition device after sending the first data packet can be reduced.

[0053] S208, when receiving the first response message corresponding to the first group of data messages, increase the sending power and reduce the receiving power, and send the second group of data messages corresponding to the second video frame to the monitoring platform in sequence according to the sequence identifier, wherein the first response message is used to indicate the message in the first group of data messages that has been received by the monitoring platform, and the playback order of the second video frame is after the first video frame.

[0054] Optionally, in an embodiment of the present application, the first response message can be used to confirm that the monitoring platform has successfully received the signal of the first group of data messages, and the second group of data messages can be some messages in the first group of data messages that have not been received by the monitoring platform, or can be data messages in the second video frame newly captured by the image acquisition device, that is, on the monitoring platform, the second video frame should not be played until the first video frame is finished playing.

[0055] Exemplarily, after receiving the first set of data packets, the monitoring platform will send a response packet to the image acquisition device to confirm that the data has been successfully received. After receiving the first response packet, the image acquisition device will increase the transmission power to ensure that subsequent data packets can be more reliably transmitted to the monitoring platform. At the same time, it will reduce the receiving power of the monitoring platform, save energy, and reduce interference.

[0056] In an exemplary embodiment, taking a camera as an image acquisition device as an example, Figure 4 As shown:

[0057] S401, the business layer first configures the frame rate configuration information of the video to the reliable transport layer based on UDP through the interface, encodes the video acquisition data into a video frame format, and calls the interface to send the encoded video frame to the reliable transport layer based on UDP;

[0058] S402, the reliable transport layer based on UDP first transmits the frame rate and other related information to the monitoring side of the other end through signaling, and slices the received service layer video frame according to the MTU size, and the video frame is divided into multiple data packets (the above-mentioned first group of data packets); the communication protocol information (sequence number, identifier, etc.) is carried in the header of each packet, and the last packet of the video frame carries the frame data end identifier (the above-mentioned sequence identifier); finally, the message encoded by the communication protocol is sent to the Wi-Fi driver module for transmission;

[0059] S403, after the camera Wi-Fi network card receives the sending command and data based on the UDP reliable transport layer, it reduces the receiving antenna power of the Wi-Fi module and increases the sending antenna power to increase the coverage of the Wi-Fi and improve the transmission quality, and then sends the message to the router through the Wi-Fi network card. When the last message of a video frame is sent, because all the messages of a video frame have been sent, the receiving antenna power of the Wi-Fi module can be increased and the sending antenna power can be reduced to prepare for better reception of the response message;

[0060] S404: The monitoring side receives the segmented video frame message, and decides whether to reply to the response message (the first response message) according to the message identification information, the frame rate configuration and the RTT information, and sorts and frames the video frame messages at the same time, and notifies the service layer to read after assembling a complete video frame;

[0061] S405, when assembling the reply message, carry information such as whether the packet is lost in the message. If a message is lost, the sequence number of the lost message needs to be carried in the reply message;

[0062] S406, after receiving the notification from the reliable transport layer based on UDP, the business layer knows that a complete video frame has been received. At this time, the business layer can read the data and decode and play it or store it for backup;

[0063] S407, after receiving the response message of the video frame message, the camera releases the video frame slice buffer space, and if the response message contains packet loss message report information, the message corresponding to the sequence number is retransmitted.

[0064] Through the embodiment of the present application, each video frame in a group of video frames captured by an image acquisition device is divided into a group of data packets, wherein each data packet includes a sequence identifier, and the sequence identifier is used to indicate the video frame to which the data packet belongs and the sending order; the sending power is increased, the receiving power is reduced, and the first group of data packets corresponding to the first video frame are sent to the monitoring platform in sequence according to the sequence identifier, wherein the first group of data packets includes a first data packet indicated by the sequence identifier as the last data packet sent in the first group of data packets; in response to the first data packet having been sent, the receiving power is increased, and the sending power is reduced; when a first response packet corresponding to the first group of data packets is received, the sending power is increased. The sending power is increased, the receiving power is reduced, and the second group of data packets corresponding to the second video frame are sent to the monitoring platform in sequence according to the sequence identifier, wherein the first response message is used to indicate the message in the first group of data messages that has been received by the monitoring platform, and the playback order of the second video frame is located after the first video frame, thereby ensuring the reliability and transmission quality of the video data transmission process, and at the same time, taking into account the dynamic adjustment of the network environment, thereby effectively improving the transmission efficiency of the video data, through the mechanism of sequence identification and response message, the data flow can be effectively managed, and unnecessary retransmission can be reduced, thereby improving the overall transmission efficiency, and then solving the technical problem of low transmission efficiency of video data.

[0065] As an optional scheme, when the first reply message corresponding to the first group of data messages is received, the above-mentioned transmission power is increased, the above-mentioned receiving power is reduced, and the second group of data messages corresponding to the second video frame are sent to the monitoring platform in sequence according to the above-mentioned sequence identifier. The above-mentioned method also includes: in response to the second data message having been sent, the above-mentioned receiving power is increased, and the above-mentioned transmission power is reduced, wherein the above-mentioned second data message indicates that the above-mentioned sequence identifier indicates that it is the last data message sent in the above-mentioned second group of data messages; when the above-mentioned second reply message is received, the above-mentioned transmission power is increased, the above-mentioned receiving power is reduced, and the third group of data messages corresponding to the third video frame are sent to the monitoring platform in sequence according to the above-mentioned sequence identifier.

[0066] Optionally, in an embodiment of the present application, the second response message can be used to confirm that the monitoring platform has successfully received the signal of the second group of data messages, the third video frame is a video frame to be transmitted after the second video frame, and the third group of data messages can be understood as a data packet containing the third video frame information that can be transmitted in the network.

[0067] In an exemplary embodiment, Figure 5 FIG. 1 is a schematic diagram of another optional video data transmission method according to an embodiment of the present application. The processing flow of the image acquisition device sending a data message is as follows: Figure 5 As shown:

[0068] S502, sending a schedule;

[0069] S504, before sending the third group of data packets corresponding to the third video frame, first check whether there is a lost packet carrying a notification in the second response packet, if yes, execute S506, otherwise execute S508;

[0070] S506, obtaining the lost message;

[0071] S508, if there is no missing packet of the second video frame, obtain the data packet of the third video frame from the cache;

[0072] S510, prepare to send a message, adjust the Wi-Fi driver module, increase the power of the transmitting antenna, and reduce the power of the receiving antenna to obtain a better communication physical layer transmission channel;

[0073] S512, sending the data message obtained from the cache through the Wi-Fi network card driver;

[0074] S514, after all the messages are sent out, the sending module will basically receive a response message of the current video frame message before sending the next video frame message, so it is necessary to adjust the Wi-Fi driver module to reduce the power of the sending antenna and increase the power of the receiving antenna to prepare for receiving the response message;

[0075] S516, end.

[0076] Through the embodiments of the present application, based on the half-duplex characteristics of the Wi-Fi network and combined with the video frame rate characteristics, the transmission response timing is calculated according to the video frame rate characteristics to avoid conflicts between the video frame data transmission message and the response message transmission under the Wi-Fi half-duplex communication mechanism, thereby improving the transmission efficiency of the video data.

[0077] As an optional scheme, when the first response message corresponding to the first group of data messages is received, the above-mentioned transmission power is increased, the above-mentioned receiving power is decreased, and the second group of data messages corresponding to the second video frame are sent to the monitoring platform in sequence according to the above-mentioned sequence identifier, including: when the above-mentioned first response message is received, the lost messages in the above-mentioned first group of data messages that have not been received by the above-mentioned monitoring platform are determined according to the above-mentioned first response message; the above-mentioned transmission power is increased, the above-mentioned receiving power is decreased, and the above-mentioned lost messages are sent to the above-mentioned monitoring platform; when the sending of the above-mentioned lost messages is completed, the above-mentioned second group of data messages are sent to the monitoring platform in sequence according to the above-mentioned sequence identifier.

[0078] Optionally, in an embodiment of the present application, the above-mentioned lost message refers to the data message in the above-mentioned first group of data messages that failed to successfully reach the monitoring platform due to various reasons (such as signal interference, network congestion, hardware failure, etc.).

[0079] Exemplarily, lost messages can be understood as data messages that fail to successfully reach the monitoring platform during transmission, data messages that the monitoring platform does not confirm receipt of in the response message, that is, data messages that need to be resent to ensure data integrity and reliability.

[0080] In an exemplary embodiment, if certain data packets are not confirmed in the first response message of the monitoring platform, then these packets are considered to be lost, namely the above-mentioned lost packets. After the lost packets are determined, the transmission power can be adjusted to increase the signal strength, while the receiving power can be reduced to reduce interference. The network driver module corresponding to the image acquisition device (such as a WiFi network card, etc.) resends those lost packets that have not been confirmed to be received. After the lost packets are successfully retransmitted, the image acquisition device will continue to send subsequent data packets in sequence, thereby achieving the technical effect of ensuring the integrity and correctness of the received data packets.

[0081] As an optional scheme, the above method also includes: obtaining frame rate configuration information pre-set for the above image acquisition device; transmitting the above frame rate configuration information to the above monitoring platform so that the above monitoring platform synchronizes the above frame rate configuration information, wherein the above monitoring platform is used to determine the frame interval duration according to the above frame rate configuration information, and determine the above first response message based on the above frame interval duration and whether the above monitoring platform receives the above first data message, and the above frame interval duration is used to indicate the interval of the above image acquisition device sending video frames to the monitoring platform.

[0082] Optionally, in the embodiment of the present application, the frame rate configuration information can be understood as the number of frames that the image acquisition device can capture per second when capturing video, that is, the frame rate (Frames Per Second, FPS) of the video, and the frame rate configuration information can be a numerical value, indicating the maximum or preset frame rate that the image acquisition device can achieve under specific conditions, and the frame interval duration refers to the time interval between two consecutive video frames. If the frame rate is 30FPS, then the frame interval duration is 1 / 30 second, or approximately 33.33 milliseconds.

[0083] In yet another exemplary embodiment, Figure 6 is a schematic diagram of another optional video data transmission method according to an embodiment of the present application. The processing flow of the monitoring platform receiving the second set of data packets is as follows Figure 6 As shown:

[0084] S602, the monitoring platform receives the data message and processes it;

[0085] S604, sort and reorganize the messages (solve the disorder problem), and then cache and combine the messages;

[0086] S606, according to the video frame rate F, calculate the frame interval time length T1 = 1000 / F (ms), for example, if the video frame rate is 25, then the interval time length T1 between frames is 40ms;

[0087] S608, calculating the difference T2 between the currently received message and the first message of the current message video frame;

[0088] S610, whether T2 is greater than T1, if so, execute S614, otherwise execute S612;

[0089] S612, when T2 is less than T1, it means that it is still within a frame interval and there is no need to respond immediately. At this time, it is determined whether the data message carries a frame end mark, that is, whether it is the last data message (the first data message mentioned above). If so, execute S614, otherwise execute S6,0;

[0090] S614, when T2 is greater than T1, it means that a frame of data message has not been sent completely within a frame interval, and a response message needs to be assembled to respond to the data;

[0091] S616, after sending the response message, determine whether it can be assembled into a complete video frame, if so, execute S618, otherwise, execute S620;

[0092] S618, notifying the service layer to receive the complete video frame;

[0093] S620, end.

[0094] Through the embodiments of the present application, it is ensured that the monitoring platform can accurately synchronize the video stream and make appropriate responses when necessary.

[0095] As an optional scheme, a frame interval duration is determined according to frame rate configuration information pre-set for an image acquisition device, wherein the frame interval duration is used to represent an interval at which the image acquisition device sends video frames to a monitoring platform; in response to the monitoring platform receiving a first data packet in a first group of data packets corresponding to a first video frame, a first moment of receiving the first data packet is determined, wherein the first video frame represents a video frame in a group of video frames acquired by the image acquisition device, each video frame in the group of video frames is respectively divided into a group of data packets for transmission, each of the data packets includes a sequence identifier, the sequence identifier is used to indicate the video frame to which the data packet belongs and the transmission order, and the first The data message represents the data message indicated by the sequence identifier as the first data message sent in the first group of data messages; whenever the monitoring platform receives other data messages in the first group of data messages except the first data message, it determines the second moment when each of the other data messages is received; when the interval between the second moment and the first moment is less than or equal to the frame interval, and the other data messages include the first data message indicated by the sequence identifier as the last data message sent in the first group of data messages, a first reply message is generated and the first reply message is sent to the image acquisition device, wherein the first reply message is used to indicate the messages in the first group of data messages that have been received by the monitoring platform.

[0096] In an exemplary embodiment, it is assumed that the image acquisition device is configured to have 30 frames per second (30fps), which means that the interval between each frame is 1 / 30 seconds, or about 33.33 milliseconds. Then, the image acquisition device starts to capture video and divides each frame of video into multiple data packets according to the preset frame rate. For example, a frame of video is divided into 5 data packets, each of which contains a sequence identifier, such as 1 / 5, 2 / 5, 3 / 5, 4 / 5, 5 / 5, and the monitoring platform starts to receive data packets from the image acquisition device. The first data packet received is the data packet with the sequence identifier 1 / 5. The monitoring platform records the time when this data packet is received, which is called the first moment.

[0097] Furthermore, the monitoring platform continues to receive the remaining data packets. Whenever a new data packet is received, the monitoring platform records the receiving time, which is called the second moment, and checks the received data packet.

[0098] It should be noted that if the interval from the first moment to the second moment is less than or equal to 33.33 milliseconds, and the received data packet is the last data packet sent in the first group of data packets (for example, 5 / 5), the monitoring platform generates a response message, which indicates to the image acquisition device that the monitoring platform has successfully received this group of data packets.

[0099] Exemplarily, a response message is sent back to the image acquisition device to confirm that the monitoring platform has received a complete frame of data, so that the image acquisition device knows that it can continue to send the next frame of data messages, or perform other operations, such as retransmitting lost data messages.

[0100] Through the embodiments of the present application, the process of data transmission and synchronization between the image acquisition device and the monitoring platform in the video monitoring system is realized, which ensures the continuity and synchronization of the video data, and also allows the monitoring platform to manage and adjust problems that may arise during the data transmission process.
