The remote acquisition end can be in various forms, such as a remote network camera or other remote intelligent terminals. The target flow data is flow data collected by a remote collection end.
If the user checks the condition of the area monitored by the remote acquisition end in advance, an acquisition request of target stream data of the remote acquisition end can be sent to the source station by using terminal equipment such as a mobile phone or other intelligent terminals provided with control programs. The acquisition request of the target stream data of the remote acquisition end can be sent to the source station in various ways, for example, a user with the remote acquisition end can send the acquisition request to the source station through a preset interface connected with the terminal device, and other users can send the acquisition request to the source station through accessing a network link shared by the user with the remote acquisition end, and other ways can also be used.
And 102, informing a remote acquisition end to acquire target stream data and pushing the target stream data to a target transmission node.
After receiving the first acquisition request of the target flow data of the remote acquisition end, the source station informs the remote acquisition end of acquiring the target flow data and pushes the acquired target flow data to the target transmission node.
Specifically, the source station may send an open flow instruction to the remote acquisition end to the management node after receiving the first acquisition request, and then the management node notifies the remote acquisition end of opening the flow and pushes the target flow data acquired by the remote acquisition end to the target transmission node.
And 103, acquiring target stream data pushed to the target transmission node, and feeding the target stream data back to a request end of the stream data.
After the remote acquisition end pushes the acquired target stream data to the target transmission node, the source station can acquire the target stream data pushed by the remote acquisition end from the target transmission node and feed the target stream data back to the request end of the stream data, namely, the request end sending the first acquisition request, so that the processes of remotely starting the remote acquisition end and acquiring the target stream data acquired by the remote acquisition end are completed, and the remote start of stream data transmission is realized. Specifically, the target streaming data may be fed back to the request end of the streaming data according to the end identifier of the stored streaming data request end. And the terminal can display the target stream data after receiving the target stream data for the user to check.
In the embodiment of the present invention, preferably, the method may further include: and pushing the acquired target streaming data to at least one other transmission node except the target transmission node so that a plurality of request ends of the target streaming data can acquire the target streaming data nearby.
The embodiment of the invention uses a Network to transmit the stream data acquired by the remote acquisition end, for example, a Content Delivery Network (CDN) is used to transmit the stream data acquired by the remote acquisition end.
The number of the request terminals for the target stream data of the remote acquisition terminal can be multiple, the multiple request terminals can be located at different geographic positions, and in order to facilitate the request terminals located at other geographic positions to pull the target stream data nearby, the embodiment of the invention can push the target stream data from the target transmission node to at least one other transmission node after the target transmission node receives the target stream data pushed by the remote acquisition terminal.
Other transmission nodes can be determined in various ways, for example, the other transmission nodes can be preset, when the first acquisition request is sent, the first acquisition request is made to carry node identifiers of the other transmission nodes, the node identifiers of the other transmission nodes are finally transmitted to the target transmission node through part or all of the devices in the source station, the management node and the remote acquisition end, and the target transmission node can determine the other transmission nodes according to the node identifiers of the other transmission nodes; alternatively, the identities of the other transfer nodes may be stored in the management node in advance, and the management node may send the identities of the other transfer nodes to the target transfer node.
In this embodiment of the present invention, preferably, before the notifying the remote acquisition end to acquire target stream data and push the target stream data to the target transmission node, the method may further include: it is determined that the requested target stream data does not exist locally.
After receiving a first acquisition request of target stream data of a remote acquisition end, a source station judges whether the requested target stream data exists locally or not, and if so, feeds back the locally stored target stream data to a request end of the target stream data; and if the target flow data does not exist, executing the next step, and informing the remote acquisition end to acquire the target flow data and pushing the target flow data to the target transmission node.
According to the embodiment of the invention, after a first acquisition request of target streaming data of a remote acquisition end is received, the remote acquisition end is informed to acquire the target streaming data and push the target streaming data to a target transmission node, and then the pushed target streaming data is acquired from the target transmission node and fed back to a request end of the streaming data, so that the remote acquisition end is remotely started, the streaming data acquired by the remote acquisition end is acquired, and the streaming data transmission is completed. The sending user of the first acquisition request is not limited to the owner of the remote acquisition end, and other users can also realize remote control on the remote acquisition end by sending the first acquisition request through terminal equipment, so that the embodiment of the invention meets the sharing requirement on the streaming data acquired by the remote camera.
Referring to fig. 2, a schematic flow chart illustrating steps of a method for remotely turning on streaming data transmission according to a second embodiment of the present invention specifically includes the following steps:
step 201, receiving a first acquisition request for target stream data of a remote acquisition end sent by accessing a network link, where the first acquisition request carries an end identifier of the remote acquisition end extracted from the network link.
In the embodiment of the invention, the network link can be a link address shared by an owner of the remote acquisition end, such as a link address shared by instant chat software, short messages and the like, and a user can control the remote acquisition end to open a stream and receive stream data acquired by the remote acquisition end by accessing the network link, so that the embodiment of the invention meets the requirements of sharing the control authority of the remote acquisition end and sharing target stream data of the remote acquisition end, and a plurality of users can watch the stream data acquired by the remote acquisition end. The web link may also be a link in a web page or other suitable link address.
The format of the network link can be preset, so that the network link shared by the user or the network link in the webpage comprises an end identifier of the remote acquisition end, for example, the sharing address is rtmp:// x.x.x.x.x/appname/StreamName, wherein the StreamName is the end identifier of the remote acquisition end, and for example, each remote acquisition end has a unique equipment number. After a user accesses a network link, a terminal device used by the user sends a first acquisition request for target stream data of a remote acquisition end to a source station, when the terminal device sends the first acquisition request, firstly, an end identifier of the remote acquisition end is extracted from the network link, the first acquisition request carries the end identifier, and then, the first acquisition request carrying the end identifier of the remote acquisition end is sent to the source station.
Step 202, extracting the end identifier carried by the first acquisition request.
After receiving the first acquisition request, the source station extracts the end identifier information carried by the first acquisition request for determining the remote acquisition end to execute the notification in advance, and then notifies the remote acquisition end corresponding to the end identifier to acquire the streaming data.
And 203, the remote acquisition end corresponding to the notification end identifier acquires target stream data and pushes the target stream data to the target transmission node.
After the end identifier carried by the first acquisition request is extracted, a remote acquisition end corresponding to the end identifier is informed to acquire target stream data, and the acquired target stream data is pushed to a target transmission node.
The target transmission node may be preset, and when the source station notifies the remote acquisition end, the notification may carry the node identifier of the target transmission node, so that the remote acquisition end may determine the corresponding target transmission node according to the node identifier and transmit the acquired streaming data to the target transmission node.
And step 204, acquiring target stream data pushed to the target transmission node, and feeding back the target stream data to a request end of the stream data.
The source station can acquire target streaming data from the target transmission node, and can feed the target streaming data back to the request end of the streaming data according to the stored end identification of the request end of the streaming data.
According to the embodiment of the invention, after a first acquisition request of target streaming data of a remote acquisition end is received, the remote acquisition end is informed to acquire the target streaming data and push the target streaming data to a target transmission node, and then the pushed target streaming data is acquired from the target transmission node and fed back to a request end of the streaming data, so that the remote acquisition end is remotely started, the streaming data acquired by the remote acquisition end is acquired, and the streaming data transmission is completed. The sending user of the first acquisition request is not limited to the owner of the remote acquisition end, and other users can also realize remote control on the remote acquisition end by sending the first acquisition request through terminal equipment, so that the embodiment of the invention meets the sharing requirement on the streaming data acquired by the remote camera.
The embodiment of the invention can share the opening address of the remote acquisition end, namely the network link, to other users, and the other users can realize the opening control of the remote acquisition end and the check of the target flow data acquired by the remote acquisition end by accessing the network link.
Referring to fig. 3, a schematic flow chart illustrating steps of a method for remotely turning on streaming data transmission according to a third embodiment of the present invention specifically includes the following steps:
step 301, receiving a first acquisition request for target stream data of a remote acquisition end, which is sent by accessing a network link, where the first acquisition request carries a service type to which the target stream data extracted from the network link belongs.
In the embodiment of the invention, the network link can be a link address shared by an owner of the remote acquisition terminal, and can also be a link in a webpage or other suitable link addresses.
The source station sends an instruction to the management node after receiving the first acquisition request, and the management node informs the remote acquisition end to acquire target stream data and pushes the target stream data to the target transmission node after receiving the instruction sent by the source station. At present, a plurality of companies develop remote acquisition terminals, and some companies use a specially-designed management node to perform instruction transmission and data transmission on a source station, the remote acquisition terminal and a target transmission node, so that after the source station receives a first acquisition request for target stream data of the remote acquisition terminal, the management node corresponding to the remote acquisition terminal needs to be determined first.
The management node corresponding to the remote acquisition end can be determined by various methods, specifically, a corresponding relation between the management node and a service type of the target streaming data can be preset in a source station, the service type can be in various forms, such as a name of the remote acquisition end, the name is formulated by a company developing the remote acquisition end, the company developing the remote acquisition end and the data type acquired by the remote acquisition end can be indicated, a service type to which the target streaming data belongs is limited in a network link shared by a user or in a webpage, when the terminal device sends a first acquisition request, the service type of the target streaming data is extracted from network connection, and then the first acquisition request is made to carry the service type. Therefore, after receiving the first acquisition request, the source station determines the management node corresponding to the service type carried by the first request according to the pre-stored corresponding relationship between the management node and the service type of the target stream data.
Based on the implementation method, when sending the first acquisition request, the terminal device enables the first acquisition request to carry the service type of the target stream data, and then sends the first acquisition request carrying the service type of the target stream data to the source station.
Step 302, extracting the service type of the target stream data carried by the first acquisition request.
After receiving the first acquisition request, the source station extracts the service type of the target stream data carried by the source station from the first acquisition request, such as the name of the remote acquisition end.
Step 303, notifying a management node corresponding to the service type, and controlling the remote acquisition end to acquire target stream data and push the target stream data to the target transmission node by the management node.
After extracting the service type to which the target streaming data belongs from the first acquisition request, the source station sends an open flow notification of the remote acquisition end to the management node corresponding to the service type, and after receiving the open flow notification sent by the source station, the management node sends an open flow instruction to the remote acquisition end and informs that the acquired streaming data is pushed to the target transmission node.
Specifically, after receiving an openflow notification sent by a source station, a management node sends an openflow request to a target transmission node, the target transmission node distributes a first-flow identifier for a remote acquisition end and feeds the first-flow identifier back to the management node, then the management node sends an openflow instruction to the remote acquisition end, the openflow instruction carries a flow identifier fed back by the target transmission node and an identifier of the target transmission node, the remote acquisition end acquires flow data after receiving the openflow instruction and pushes the acquired flow data to the target transmission node according to the identifier of the target transmission node, and the pushed flow data carries the distributed flow identifier.
After receiving the pushed stream data, the target transmission node can establish a corresponding relation between the stream identification and the target stream data; or generating the playing address of the stream data, and establishing the corresponding relation between the stream identification and the playing address. The management node may send a viewing request to the target transmission node, and specifically, after sending the streaming start request, the management node may send the viewing request to the target transmission node according to a preset time interval, limit the stream identifier allocated by the target transmission node to be carried in the request, and the target transmission node extracts corresponding target streaming data or a broadcast address according to the stream identifier carried in the request and feeds the target streaming data or the broadcast address back to the management node.
