DETAILED DESCRIPTION

[0044] Here, exemplary embodiments are described in detail, and examples thereof are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application.

[0045] When a recorder used in one industry is to be applied to other industries that use other protocols, the existing technology can only require manufacturers to modify the video transmission protocol at the cost of time, labor, and technology.

[0046] However, on the one hand, it is difficult to modify the protocol and wastes human and material resources. The fundamental reason is that the existing technology has a problem of limited scenarios due to the single video transmission protocol of the recorder.

[0047] In other words, manufacturers who produce recorders often only provide corresponding video return services for specific fields, and do not have sufficient understanding of video return services in other fields and other protocols. Ultimately, the recorder can only realize one video return function. The video transmission protocol used by the video return function is single, and only supports interaction with the video receiving server that implements the video transmission protocol to realize video transmission. The recorder provided by the prior art has a small scope of application. When the recorder is to be applied to other industries that adopt other protocols, the video return function will not be able to play a role.

[0048] On the other hand, for the video return service of a single video transmission protocol, since the configuration information of the video transmission protocol is fixed, the video receiving server can simply perform a simple analysis after receiving the video; if two or more video transmission protocols are involved, the differences between different video transmission protocols need to be considered, and the previous simple analysis method will not be applicable. If the protocol configuration parameters of multiple video transmission protocols are inconsistent, if the single structure provided by the existing technology is still used for data storage, there will be a problem of storage difficulty.

[0049] In order to solve the above technical problems, the overall inventive concept of the present application is to provide a method for adapting to different video transmission protocols used by different clients and improving the applicability of the recorder in the field of video surveillance.

[0050] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0051] Embodiment 1:

[0052] Figure 1 A flowchart of a video transmission control method provided in an embodiment of the present application is shown in FIG. Figure 1 As shown, the method of this embodiment includes the following steps:

[0053] S10, after the recorder is started and connected to the target network, the video return management service of the recorder is started, so that the video return management service creates a first socket interface, a message protocol management interface and a video return initialization interface on the recorder side. The target network is the network where the client is located.

[0054] It should be understood that the recorder may be called a recorder device, a video sending server, etc., and the client may be called a video receiving server. The client is generally a server of a power company or a server of a certain unit. The first socket interface may be called a server socket interface, denoted as SocketServer, which is a listening port, the message protocol management interface is denoted as ProtocolMessageManage, and the video upload initialization interface is denoted as VideoUploadInitial.

[0055] The embodiments of the present application can set different video return protocols for the recorder, so that the recorder can support multiple video transmission protocols, such as Real-Time Streaming Protocol (RTSP), ONVIF protocol, Real-Time Messaging Protocol (RTMP), HTTP Live Streaming (HLS) protocol, GB / T28181 protocol, and a new generation of streaming media transmission based on HTTP (Dynamic Adaptive Streaming over HTTP, Dash) protocol.

[0056] S20, in response to the target connection request carrying the identification information of the client received through the first socket interface, establish a Socket connection between the recorder and the client; wherein the target connection request is a connection request sent by the client through the second socket interface created by the client. The connection request is also called a link request. The second socket interface is recorded as SocketClient.

[0057] After the SocketServer is created, the SocketServer is used to bind and listen to a fixed port (or local port) to check whether there is access to the second socket interface SocketClient of the client.

[0058] S30. Send a query request containing the identification information of the client to the local database through the message protocol management interface, so that the local database can search for the protocol configuration information of the client according to the identification information of the client; wherein the protocol configuration information is the configuration information of the video transmission protocol adopted by the client.

[0059] In the embodiment of the present application, the video transmission protocol is also called the video return protocol. The identification information of the client may be an IP address or other identification; the protocol configuration information includes at least one of the following: a protocol type, a protocol configuration parameter, and an identification indicating whether to automatically start the video stream. Furthermore, the protocol configuration information of the client is stored in a preset global protocol configuration information table of the local database in a structure or in a combination of an enumeration type and a structure. This part of the content is specifically described in the following embodiment 2 and will not be repeated here.

[0060] In an embodiment of the present application, when the client accesses the recorder for the first time, the recorder interacts with the client and obtains the protocol configuration information of the video transmission protocol adopted by the client through ProtocolMessageManage, and stores it in the local database. When the client accesses again, it can be read directly from the local database.

[0061] S40, after finding the protocol configuration information, disconnect the Socket connection. This embodiment can release space and save resources by disconnecting the connection.

[0062] S50. After disconnecting the Socket connection, start the video return service corresponding to the protocol configuration information in the recorder through the video return initialization interface, so that the video return service interacts with the client at the control level, and sends the video stream collected by the recorder to the client.

[0063] In an embodiment of the present application, a recorder includes multiple video return services, and each video return service corresponds to a video transmission protocol. The embodiment of the present application does not specifically limit the acquisition time of the video stream, so the video stream can be collected by the recorder in real time, or it can be collected by the recorder at a historical time node, and this embodiment does not specifically limit this. When the video is returned, the recorder can transmit according to the preset data stream return rules.

[0064] VideoUploadInitial is used to start the video uplink service of the corresponding protocol according to the protocol configuration information, so that the video uplink service corresponding to the video transmission protocol adopted by the client can transmit the video stream.

[0065] It should be understood that different video transmission protocols differ greatly at the control level but less at the video stream transmission level. For this scenario, this embodiment can manage the video transmission protocol before the video backhaul is initiated to achieve effective control of multiple video transmission protocols. This embodiment completes the management of multiple video transmission protocols through the established video backhaul control mechanism. That is, after the recorder is started and connected to the network, this embodiment adds three interfaces to complete the control of the protocol configuration information, specifically:

[0066] After the recorder is started and connected to the network, a SocketServer is created. The SocketServer is used to bind and listen to a fixed port. When a client accesses, it checks whether the client's IP exists in the preset global protocol configuration information table stored in the local database. If so, the corresponding protocol configuration information stored in the local database is read according to the client's IP, and then the connection with the client is disconnected, and the video return service is started according to the protocol configuration information; if the local database does not find the client's IP, a message is sent and waits to receive the protocol configuration information sent by the client. After receiving the protocol configuration information sent by the client, the video return management service stores the protocol type, protocol configuration parameters, whether to automatically start the video stream, and other information locally, and starts the corresponding video return service according to the protocol configuration information, so that the corresponding video return service can realize the effective transmission of the video stream.

[0067] The video transmission protocol used by the recorder in the prior art is single, and only supports data transmission with the video receiving server that implements the protocol. It has a small scope of application and cannot adapt to multiple protocols. Compared with the prior art, the embodiment of the present application provides a frequency return control method, which is an adaptive video stream control method based on Socket communication. The method creates three interfaces, namely a first socket interface, a message protocol management interface and a video return initialization interface, through the video return management service of the recorder, and realizes the control of the configuration information of the video transmission protocol used by the client through the function of each interface, thereby enabling the recorder to adapt to different video transmission protocols used by different clients, thereby improving the applicability of the recorder.

[0068] In a possible implementation, the video transmission protocol adopted by the client is the RTSP protocol, the ONVIF protocol, the RTMP protocol, the HLS protocol, the GB / T28181 protocol or the Dash protocol.

[0069] The recorder in the embodiment of the present application can manage the above-mentioned multiple video transmission protocols through the video return management service, and then can communicate with different clients using different video transmission protocols, thereby improving the convenience of video return and the applicability of the recorder.

[0070] In a possible implementation, after the protocol configuration information is found and before the socket connection is disconnected, the method further includes:

[0071] S60. Send second flag information to the client through the message protocol management interface; wherein the second flag information is used to indicate that protocol configuration information is stored in the local database.

[0072] The above steps S10 to S50 and step S60 are all specific steps in the video return control mechanism. This embodiment establishes a video return control mechanism, through which the compatibility of multiple video transmission protocols is achieved, and all implemented video transmission protocols are controlled. Specifically, it creates a SocketServer, binds a local port, listens for link requests, and manages the received client's protocol configuration information after accessing the link. When accessing again, the video return service corresponding to the video transmission protocol adopted by the client is adaptively started.

[0073] After step S30, in addition to finding the protocol configuration information, this embodiment may also fail to find the protocol configuration information. In the case where the protocol configuration information cannot be found, the embodiment of the present application provides another video return control method.

[0074] Embodiment 2:

[0075] Figure 2A flowchart of another video transmission control method provided in an embodiment of the present application. Figure 2 As shown, another video return control method includes:

[0076] S21, after the recorder is started and connected to the target network, the video return management service of the recorder is started, so that the video return management service creates a first socket interface, a message protocol management interface and a video return initialization interface on the recorder side. The target network is the network where the client is located.

[0077] S22. In response to a target connection request carrying identification information of the client received through the first socket interface, establish a Socket connection between the recorder and the client; wherein the target connection request is a connection request sent by the client through the second socket interface created by the client.

[0078] S23. Send a query request containing the identification information of the client to the local database through the message protocol management interface, so that the local database can search for the protocol configuration information of the client according to the identification information of the client; wherein the protocol configuration information is the configuration information of the video transmission protocol adopted by the client.

[0079] It should be understood that the specific implementation of steps S21 to S23 is the same as Figure 1 Steps S10 to S30 are similar and will not be described in detail here.

[0080] S24. When the protocol configuration information is not found, sending first flag information to the client through the message protocol management interface; wherein the first flag information is used to indicate that the protocol configuration information is not stored in the local database;

[0081] S25, receiving feedback information sent by the client based on the first flag information, storing the protocol configuration information in the feedback information and the identification information of the client in a preset global protocol configuration information table of the local database in correspondence with each other according to the target storage method, and disconnecting the Socket connection.

[0082] S26. After disconnecting the Socket connection, start the video return service corresponding to the protocol configuration information in the recorder through the video return initialization interface, so that the video return service interacts with the client at the control level, and sends the video stream collected by the recorder to the client.

[0083] It should be understood that the specific implementation of step S26 is the same as Figure 1 The process is similar to step S50 in , and will not be described in detail here.

[0084] Compared with the prior art, the embodiment of the present application creates three interfaces, namely the first socket interface, the message protocol management interface and the video return initialization interface, through the video return management service of the recorder, and realizes the management and control of the configuration information of the video transmission protocol adopted by the client through the function of each interface, thereby enabling the recorder to adapt to different video transmission protocols adopted by different clients, thereby improving the applicability of the recorder.

[0085] In a possible implementation, the target storage method is a structure method, or a method combining an enumeration type and a structure.

[0086] In view of the difficulty in storing multiple protocol configuration information in the prior art, this embodiment establishes a data structure set associated with the video transmission protocol, and adopts a design pattern combining enumeration type and structure to realize global storage of protocol configuration information. This embodiment stores the protocol type in the protocol configuration information in the form of enumeration, and each protocol type corresponds to its own protocol configuration structure.

[0087] In a possible implementation, the identification information of the client is an IP address; the protocol configuration information includes at least one of the following: a protocol type, a protocol configuration parameter, and an identifier for indicating whether to automatically start a video stream.

[0088] This embodiment establishes a preset global protocol configuration information table, which is used to store protocol configuration information of various video transmission protocols. The table mainly includes: client IP, protocol type of video transmission protocol, configuration parameters of video transmission protocol, whether to automatically start video stream, etc. Optionally, this embodiment uses a combination of enumeration type and structure to store protocol type, configuration parameters, etc. of video transmission protocol, that is, protocol type and configuration parameters correspond one to one.

[0089] This embodiment stores the identification information and protocol configuration information of the client that has accessed previously in a preset global protocol configuration information table. When the same client accesses next time, this embodiment can traverse and obtain the corresponding protocol configuration information from the above table based on the identification information of the client, and then start the corresponding video return service based on the obtained protocol configuration information, thereby improving the applicability of the recorder.

[0090] In a possible implementation, after receiving feedback information sent by the client based on the first flag information in step S25, the method further includes:

[0091] S27. Send confirmation information indicating receipt of the feedback information to the client through the message protocol management interface.

[0092] Step S27 can ensure information synchronization between the communicating parties (client and recorder), prevent failure in sending protocol configuration information due to poor network / client downtime, and thus ensure accuracy of protocol configuration information management.

[0093] Based on the above embodiments, the technical solution of the present application is described in more detail below in combination with several specific embodiments.

[0094] Figure 3 The structure diagram of a video return control system provided in the embodiment of the present application is shown in FIG. Figure 3 As shown, the video return control system includes a client 31 and a recorder 32. The recorder includes a video return management service module 321 and a video return service module 322, wherein the video return service module 322 is used to provide multiple video return services using different video transmission protocols. The video return control system is used to provide a video return control method.

[0095] exist Figure 3 On the basis of Figure 4 A flowchart of another video transmission control method provided in an embodiment of the present application is shown below. Figure 4 As shown, the method of this embodiment includes the following steps:

[0096] S401, after the video transmission management service module is powered on and connected to the network, a SocketServer is established.

[0097] S402: The client establishes a SocketClient.

[0098] S403: The client initiates a connection request carrying the client's IP.

[0099] S404, the video return management service module establishes a connection and queries the client's protocol configuration information according to the client's IP. After executing step S404, this embodiment determines whether to execute the following steps S405 to S408 or step S409 according to the query result.

[0100] S405: The video return management service module sends a non-storage flag. It should be understood that the non-storage flag corresponds to the first flag information in the second embodiment.

[0101] S406: The client sends protocol configuration information.

[0102] S407: The video transmission management service module saves the protocol configuration information and the client's IP.

[0103] S408: The video return management service module sends a receiving reply message to the client. It should be understood that the receiving reply message is equivalent to the feedback information in the second embodiment.

[0104] S409: The video transmission management service module sends a stored flag to the client. It should be understood that the stored flag corresponds to the second flag information in the first embodiment.

[0105] S410: The video transmission management service module disconnects the connection and sends a disconnection message to the client.

[0106] S411. The video return management service module starts the video return service.

[0107] S412: The video backhaul service module interacts with the client at the control level.

[0108] S413: The video backhaul service module performs video stream transmission.

[0109] Based on the operations of the above steps S401 to S413, this embodiment has put the above technical solution into practical application. For example, a company in the first area uses the RTSP protocol for video transmission, and another company in the second area uses the GB / T28181 protocol for video transmission. In order to implement these two video transmission protocols, the recorder combines this solution to complete the management and control of the two video transmission protocols, that is, when the video is transmitted based on the RTSP or GB / T28181 protocol for the first time, a Socket is established for interaction to obtain the protocol configuration information of the RTSP protocol or the GB / T28181 protocol. When each company accesses again, the recorder can adaptively read the protocol configuration information of the video transmission protocol pre-stored in the local database through the video transmission management service, and then quickly initiate the video transmission service of the corresponding protocol. This embodiment not only broadens the application scenarios of the recorder, but also effectively solves the problem of difficult management of different video transmission protocols.

[0110] By executing the operations of steps S401 to S413 above, the embodiment of the present application can study the video backhaul of the recorder. The proposed scheme realizes the management and control of adaptive video backhaul services based on multiple video transmission protocols, which can be applied in multiple fields of different video transmission protocols, thereby expanding the scope of use of the recorder.
