[0040] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0041] An embodiment of the present invention provides a data transmission method for processing parallel requests. The execution subject of this embodiment is a data transmission device, which is arranged on a server.

[0042] Reference Figure 1 , shows a flow chart of a data transmission method embodiment of the present invention, the method may specifically include the following steps:

[0043] S101, receiving viewing requests sent by multiple viewing terminals, where the viewing requests are used to request monitoring data of the same monitoring resource identifier;

[0044] Specifically, multiple viewing terminals are connected to a streaming media server, and the streaming media server is connected to each monitoring device through a coordination server. The streaming media server receives viewing requests for viewing monitoring sent by multiple viewing terminals, wherein the viewing requests are used to request monitoring data of the same monitoring resource identifier, and the monitoring resource identifier at least includes a monitoring device identifier, a monitoring start time, and a monitoring end time.

[0045] Exemplarily, terminal 1 to terminal 5 request to watch the monitoring video of monitoring device 1 from 10:00 to 10:30.

[0046] S102, judging the viewing request, if the viewing request is the first request, obtaining monitoring data corresponding to the monitoring resource identifier, and recording the monitoring data to generate recording file information;

[0047] Specifically, the monitoring data in the embodiment of the present invention is video data, wherein the video data refers to monitoring images saved within a certain period of time.

[0048] When receiving a viewing request, the streaming media server determines whether the viewing request is the first request for the monitoring resource identifier based on the monitoring resource identifier. If it is the first request, the monitoring data corresponding to the monitoring resource identifier is obtained from the monitoring device through the coordination server.

[0049] In the specific implementation process, when the streaming media server determines that the viewing request is the first request, it sends the viewing request to the co-conversion server. The co-conversion server obtains the monitoring data corresponding to the monitoring resource identifier from the monitoring device according to the monitoring resource identifier, and publishes the live broadcast corresponding to the monitoring data in a live broadcast manner through the virtual terminal installed on the co-conversion server. An idle virtual terminal is searched on the streaming media server, and a live broadcast channel with the co-conversion server is established. The live broadcast data published by the co-conversion server is received through the live broadcast channel, and the received live broadcast data is recorded to obtain the recording file information.

[0050] The recording file information includes not only the recording file, but also address information corresponding to the recording file generated according to the recording file.

[0051] For example, the streaming media server receives viewing requests sent by terminals 1 to 5, all of which are requests to view the monitoring video of monitoring device 1 from 10:00 to 10:30. The streaming media server judges the five viewing requests, determines the viewing request received first according to the order of the received time, and sends the viewing request to the coordination server. The coordination server obtains the monitoring data of monitoring device 1 from 10:00 to 10:30, and uses a virtual terminal to broadcast the monitoring data in a live broadcast mode. The streaming media server establishes a live broadcast channel for receiving the live broadcast data. When the live broadcast video starts to be received, the monitoring data starts to be recorded and the recording file information is generated.

[0052] S103: Send the recorded file information to multiple viewing terminals.

[0053] Specifically, after the streaming media server completes recording of the monitoring data identified by the monitoring resource, if it receives a viewing request sent by other viewing terminals during the recording process, the viewing request will not be processed until the recording of the monitoring data is completed. The streaming media server sends the recording file information to all viewing terminals that send viewing requests. In this way, there is no need for multiple viewing terminals to download the monitoring data in sequence. The same recording file information can be sent to multiple viewing terminals at the same time, which reduces the time the viewing terminals wait for downloading, reduces time extension, and improves data transmission efficiency.

[0054] The data transmission method provided by the embodiment of the present invention receives viewing requests sent by multiple viewing terminals, where the viewing requests are used to request monitoring data of the same monitoring resource identifier; judges the viewing requests, and if the viewing request is the first request, obtains the monitoring data corresponding to the monitoring resource identifier, and records the monitoring data to generate recording file information; sends the monitoring information to multiple viewing terminals, so that the server receives multiple viewing requests at the same time and judges the viewing requests. Only when the viewing request is received for the first time, the server obtains the monitoring data corresponding to the monitoring resource identifier from the monitoring device, and records the monitoring data to obtain the recording file information. During the recording process, the viewing requests received no longer re-acquire the monitoring data for recording, but send the recorded recording file information to all viewing terminals. In this way, there is no need for multiple viewing terminals to download the monitoring data in sequence, and the same recording file information is sent to multiple viewing terminals at the same time, which reduces the time for the viewing terminals to wait for downloading, reduces the time extension, and improves the data transmission efficiency.

[0055] Another embodiment of the present invention further supplements the data transmission method provided by the above embodiment.

[0056] like Figure 2 FIG. 1 is a flowchart showing another data transmission method embodiment of the present invention, wherein the data transmission method comprises:

[0057] S201. Receive viewing requests sent by multiple viewing terminals, where the viewing requests are used to request monitoring data of the same monitoring resource identifier; the monitoring resource identifier at least includes a monitoring device identifier, a monitoring start time, and a monitoring end time.

[0058] Specifically, multiple viewing terminals are connected to a streaming media server, and the streaming media server is connected to each monitoring device through a coordination server. The streaming media server receives viewing requests for viewing monitoring sent by multiple viewing terminals, wherein the viewing requests are used to request monitoring data of the same monitoring resource identifier, and the monitoring resource identifier at least includes a monitoring device identifier, a monitoring start time, and a monitoring end time.

[0059] S202, judging the viewing request;

[0060] When receiving multiple viewing requests, the streaming media server determines whether it is the first request based on the receiving time. If it is the first request, step S203 is executed; if it is not the first request, no processing is performed.

[0061] S203: If the viewing request is a first request, receiving monitoring data corresponding to the monitoring resource identifier through a live broadcast channel;

[0062] Specifically, when receiving a viewing request, the streaming media server determines whether the viewing request is the first request for the monitoring resource identifier based on the monitoring resource identifier. If it is the first request, the monitoring data corresponding to the monitoring resource identifier is obtained from the monitoring device through the coordination server.

[0063] In the specific implementation process, when the streaming media server determines that the viewing request is the first request, it sends the viewing request to the co-transmission server. The co-transmission server obtains the monitoring data corresponding to the monitoring resource identifier from the monitoring device according to the monitoring resource identifier, and publishes the live broadcast corresponding to the monitoring data in a live broadcast manner through the virtual terminal installed on the co-transmission server. The streaming media server searches for an idle virtual terminal, establishes a live broadcast channel with the co-transmission server, and receives the live broadcast data published by the co-transmission server through the live broadcast channel.

[0064] For example, the streaming media server receives viewing requests sent by terminals 1 to 5, all of which are requests to view the monitoring video of monitoring device 1 from 10:00 to 10:30. The streaming media server judges the five viewing requests, determines the viewing request received first according to the order of the received time, and sends the viewing request to the coordination server. The coordination server obtains the monitoring data of monitoring device 1 from 10:00 to 10:30, and uses a virtual terminal to broadcast the monitoring data in a live broadcast mode. The streaming media server establishes a live broadcast channel for receiving the live broadcast data. When the live broadcast video starts to be received, the monitoring data starts to be recorded and the recording file information is generated.

[0065] S204, recording the monitoring data into a monitoring file in MP4 format;

[0066] Specifically, the streaming media server starts recording the monitoring data at the same time as it starts receiving the monitoring data. During the recording process, based on the characteristics that the data volume remains unchanged but the download transmission is much faster than the normal playback, when recording the MP4 file, the timestamps of all video frames need to be reassigned to ensure that the data is played stably at normal multiples. For example, the timestamp of each video frame is increased by 40ms, and the monitoring data with the increased time is saved until the reception is completed and a recording file is generated.

[0067] The recording file information includes not only the recording file, but also address information corresponding to the recording file generated according to the recording file.

[0068] S205. Generate address information corresponding to the recording file according to the recording file.

[0069] In order to reduce the network bandwidth for transmission, the streaming media server generates address information corresponding to the recording file, namely, URL (uniform resource locator; uniform resource locator system) according to the recording file.

[0070] S206: When the recording file is finished, close the live broadcast channel.

[0071] Specifically, after the streaming media server completes recording the recording file, it closes the live broadcast channel. When a new viewing terminal wants to watch the monitoring resources of other monitoring resource identifiers, it needs to re-establish the live broadcast channel. By connecting the live broadcast channels, the operating pressure of the streaming media server can be reduced.

[0072] S207: Send the address information to multiple viewing terminals, so that the multiple viewing terminals download the monitoring data corresponding to the monitoring resource identifier according to the address information.

[0073] Specifically, after the streaming media server completes recording the file, it sends the URL of the generated recording file to multiple viewing terminals. Each viewing terminal downloads the monitoring data corresponding to the monitoring resource identifier according to the address information. In this way, there is no need for multiple viewing terminals to download the monitoring data in sequence. The same recording file information can be sent to multiple viewing terminals at the same time, which reduces the time the viewing terminals spend waiting for downloading, reduces time extension, and improves data transmission efficiency.

[0074] Figure 3 FIG. 1 is a flowchart of another embodiment of a data transmission method of the present invention. Figure 3 As shown, the data transmission method includes:

[0075] S301, select a monitoring channel and a video time period to request Q to download the video.

[0076] Specifically, the streaming media server receives viewing requests sent by multiple viewing terminals Q, where the viewing requests are used to request monitoring data of the same monitoring resource identifier, where the monitoring resource identifier includes a monitoring device identifier, a monitoring start time, and a monitoring end time.

[0077] S302: Determine whether there is a live broadcast channel.

[0078] The streaming media server determines whether there is a live broadcast channel at present. If there is a live broadcast channel, it means that monitoring data is being recorded. If there is no live broadcast channel, a live broadcast channel needs to be established to obtain monitoring data from the protocol server.

[0079] S303, if there is no live channel, the viewing request is sent to the cooperative server, and the cooperative server pulls the video data (monitoring data) of the same time period on the monitoring device, binds the data stream to an idle virtual terminal, and publishes the live broadcast. The streaming media server uses an idle virtual terminal to watch the live data of the cooperative server, i.e., the monitoring data, and creates a live channel, records information such as terminal Q, and introduces the received monitoring data, i.e., data stream information, into the channel of terminal Q. The streaming media server determines whether the live channel and terminal Q are the first requester. If so, it records the MP4 file and records the monitoring data into an MP4 file, i.e., a recording file.

[0080] If there is a live broadcast channel, it means that the streaming media server is already recording and will not process the request sent by the viewing terminal, waiting for notification.

[0081] S304, the live broadcast channel receives the monitoring data sent by the cooperative conversion server through the live broadcast channel.

[0082] S305, starting from 0, add 40ms to the timestamp of each frame.

[0083] During the recording process, the streaming media server resets the timestamp of each video frame received, for example, the timestamp of each frame is increased by 40ms, so that when the viewing terminal plays it, it can be played at a normal rate without accelerated playback.

[0084] S306: After recording is completed, a recording file in MP4 format is generated, and a URL corresponding to the recording file is generated;

[0085] S307: The streaming media server sends the URL to multiple viewing terminals, so that the multiple viewing terminals download the monitoring data corresponding to the monitoring resource identifier according to the address information URL.

[0086] The embodiment of the present invention adopts a live broadcast channel to download surveillance video, reducing the occupation of virtual terminals. In the embodiment of the present invention, what is broadcast live is video data, not real-time data. If there is a request, a live broadcast channel A is created for the same surveillance video and the same period of time. The receiving channel A, i.e., the live broadcast channel, is created only for the first requesting terminal. The video data is received through the live broadcast channel, and the received video data is saved and converted into an MP4 file. After that, the requesting terminal joins this channel A without stream data processing. After the first requesting terminal receives the surveillance data stream through the live broadcast channel and generates an MP4 file, the save address of the MP4 file is sent to all viewing terminals so that the viewing terminals can download it.

[0087] When recording an MP4 file, the embodiment of the present invention reassigns the timestamps of all frames in the recorded MP4 file based on the characteristic that the data volume remains unchanged but the download transmission is much faster than the normal playback, thereby ensuring that the data playback is stably played at a normal multiple.

Only when the viewing request is received for the first time, the server obtains the monitoring data corresponding to the monitoring resource identifier from the monitoring device, and records the monitoring data to obtain the recording file information. During the recording process, the viewing requests received no longer re-acquire the monitoring data for recording, but send the recorded recording file information to all viewing terminals.
