The core idea of the embodiment of the invention is that whether the decoding capability of the video network terminal is matched with the monitoring resource is judged, when the decoding capability of the video network terminal does not meet the monitoring resource, the monitoring resource sent to the video network terminal is transcoded, and when the decoding capability of the video network terminal meets the monitoring resource, the transcoding is not needed; by carrying out different code stream conversion according to different decoding capabilities of the video network terminal, the video network terminal with high performance is prevented from only receiving the transcoded monitoring resources, and the high efficiency of the video network terminal in watching the monitoring resources is realized.
It should be noted that, when the user selects the video network terminal to view the monitoring service, the involved devices may include an operation level transcoder, a monitoring access service system, a video network terminal, and a video network server.
The operation level transcoder is a hardware device, wherein a hardware board card can be used for decoding and then encoding multimedia resources, in the embodiment of the invention, the transcoder can be communicated with a monitoring access service system through a self-defined private protocol, and can decode and then encode monitoring resources sent by the monitoring access service system; the customized proprietary protocol may be a protocol established by the monitoring access service system and the transcoder in a negotiation manner.

The video networking server can be a real-time high-speed transmission network based on Ethernet hardware, and can be used for a special network for transmitting high-definition videos and special protocols; and the terminal carries the main service of the video network, sends control signaling to the terminal and responds to some request signaling.
Referring to fig. 1, a flowchart illustrating a first step of a monitoring resource transmission method according to an embodiment of the present invention is shown, where the method is applied to a monitoring access server, where the monitoring access server is connected to a video network terminal and a transcoder, and specifically includes the following steps:
step 101, the monitoring access server receives a monitoring resource request sent by the video network terminal and acquires original monitoring resource information according to the monitoring resource request;
the monitoring access server is connected with the video network terminal, so that the monitoring access server can receive a monitoring resource request generated by the video network terminal, and can also acquire original monitoring resource information corresponding to the monitoring resource request according to the monitoring resource request, so that the monitoring access server can judge whether the decoding capability information of the video network terminal is matched with the original monitoring resource information; the original monitoring resource information may include an original monitoring resource corresponding to the monitoring resource request and original monitoring data for the original monitoring resource.
In an embodiment of the present invention, the original monitoring resource corresponding to the monitoring resource request acquired by the monitoring access server can be directly acquired by the monitoring resource platform responding to the monitoring resource request sent by the monitoring access server; the original monitoring data for the original monitoring resource acquired by the monitoring access server can be analyzed by the monitoring access server after receiving the original monitoring resource, so as to obtain data such as resolution, coding format and the like of the original monitoring resource.
102, the monitoring access server acquires decoding capability information aiming at the video networking terminal;
after the monitoring access server acquires the original monitoring resource information according to the monitoring resource request, the monitoring access server can acquire the decoding capability information of the video network terminal because whether the decoding capability information of the video network terminal is matched with the original monitoring resource information needs to be judged.
In an embodiment of the present invention, since the monitoring access server may receive a monitoring resource request generated from the video network terminal, the monitoring access server may directly obtain decoding capability information of the video network terminal through the monitoring resource request, and the monitoring access server may also obtain the decoding capability information from an information base in which decoding capability information of various types of video network terminals is stored in advance. The method for acquiring the decoding capability information of the video network may be implemented by the above method, or by other methods, which is not limited in this embodiment of the present invention.
103, the monitoring access server acquires target monitoring resource information through the transcoder according to the decoding capability information and the original monitoring resource information;
in an embodiment of the present invention, after the monitoring access server obtains the original monitoring resource information corresponding to the monitoring resource request and obtains the decoding capability information corresponding to the video network terminal that generates the monitoring resource request, the monitoring access server may determine whether the decoding capability information of the video network terminal matches the original monitoring resource information according to the decoding capability information and the original resource information, and obtain the target monitoring resource information through the transcoder according to the determination result, so as to send the target monitoring resource information to the video network terminal.
And 104, the monitoring access server sends the target monitoring resource information to the video network terminal.
In an embodiment of the present invention, the monitoring access server may send the target monitoring resource information to the video networking terminal after determining whether the decoding capability information of the video networking terminal matches the original monitoring resource information and acquiring the target monitoring resource information according to the determination result; the target monitoring resource information may include a target monitoring resource and target monitoring resource data, so that the video network terminal plays the target monitoring resource.
It should be noted that the target monitoring resource may be a monitoring resource that can be decoded normally by the video networking terminal, and the target monitoring resource data may be data such as resolution and encoding format that are matched with the decoding capability information of the video networking terminal.
In an embodiment of the present invention, the original monitoring resource information includes an original monitoring resource and original monitoring data; step 103 may comprise the following sub-steps:
substep S11, the monitoring access server determining whether the decoding capability information matches the original monitoring data;
in an embodiment of the present invention, after the monitoring access server obtains the original monitoring resource information corresponding to the monitoring resource request and obtains the decoding capability information corresponding to the video network terminal that generates the monitoring resource request, since the original monitoring resource information may include the original monitoring resource corresponding to the monitoring resource request and the original monitoring data for the original monitoring resource, the original monitoring data refers to data such as resolution and encoding format of the original monitoring resource, in order to avoid that the video network terminal with high performance can only receive the transcoded monitoring resource, the monitoring access server may determine whether the decoding capability information of the video network terminal matches with the original monitoring resource information, and obtain the target monitoring resource information according to the determination result.
Substep S12, if the decoding capability information does not match the original monitoring data, the monitoring access server obtains target monitoring resource information through the transcoder;
because the hardware transcoder is always hung under the monitoring access server, under one condition, the hardware transcoder can be used for transcoding the original monitoring resource in the original monitoring resource information under the condition that the decoding capability information of the video network terminal is not matched with the original monitoring data to obtain the transcoded original monitoring resource information, namely, the target monitoring resource information is generated, so that the transcoder can send the target monitoring resource information to the monitoring access server.
In an embodiment of the present invention, the sub-step S12 may include the following sub-steps:
substep S121, the monitoring access server sends the original monitoring resource information and the decoding capability information to the transcoder;
in an embodiment of the present invention, when the decoding capability information of the video network terminal is not matched with the original monitoring data, since the transcoder transcodes the original monitoring resource information, the monitoring access server may send the original monitoring resource information and the decoding capability information of the video network terminal to the transcoder, so that the transcoder transcodes the original monitoring resource according to the original monitoring data and the decoding capability information of the video network terminal, and obtains the target monitoring resource information.
Substep S122, the monitoring access server receives the target monitoring resource information sent by the transcoder; and the target monitoring resource information is the monitoring resource information obtained after the transcoder transcodes the original monitoring resource according to the decoding capability information.
In an embodiment of the present invention, the method for transcoding the original monitoring resource information by the transcoder to obtain the target monitoring resource information may be that the original monitoring resource in the original monitoring resource information is decoded, and then the decoded original monitoring resource is encoded according to the decoding capability information of the video network terminal, where the encoded original monitoring resource is the target monitoring resource; after the target monitoring resource is obtained, the transcoder can generate target monitoring data according to information such as the resolution, the coding format and the like of the target monitoring resource, namely, the original monitoring data is updated to be the target monitoring data; the transcoder may use the target monitoring resource and the target monitoring data obtained after transcoding as target monitoring resource information, and send the target monitoring resource information to the monitoring access server.
And a substep S13, if the decoding capability information matches the original monitoring data, the monitoring access server sends the original monitoring resource information to the video network terminal.
Because the hardware transcoder is always hung under the monitoring access server, under another condition, the video network terminal has high performance under the condition that the decoding capability information of the video network terminal is matched with the original monitoring data, in order to avoid that the video network terminal with high performance can only receive the transcoded monitoring resource, the monitoring access server can directly send the received original monitoring resource information to the video network terminal without sending the original monitoring resource information received according to the monitoring resource request to the transcoder, so that the video network terminal with high performance can directly play the original monitoring resource instead of the monitoring resource transcoded by the transcoder.
According to the transmission method of the monitoring resources, whether the decoding capability of the video network terminal is matched with the monitoring resources or not is judged, when the decoding capability of the video network terminal does not meet the monitoring resources, the monitoring resources sent to the video network terminal are transcoded, and when the decoding capability of the video network terminal meets the monitoring resources, transcoding is not needed; by carrying out different code stream conversion according to different decoding capabilities of the video network terminal, the video network terminal with high performance is prevented from only receiving the transcoded monitoring resources, and the high efficiency of the video network terminal in watching the monitoring resources is realized.
Referring to fig. 2, a flowchart illustrating steps of a second embodiment of a method for transmitting a monitoring resource according to the present invention is shown, where the method is applied to a video networking terminal, the video networking terminal is connected to a monitoring access server, and the monitoring access server is connected to a transcoder, and specifically includes the following steps:
step 201, the video network terminal generates a monitoring resource request and sends the monitoring resource request to the monitoring access server; the monitoring resource request comprises decoding capability information aiming at the video networking terminal;
in an embodiment of the present invention, since the video network terminal is connected to the monitoring access server, the video network terminal may generate a monitoring resource request and send the monitoring resource request to the monitoring access server, so that the monitoring access server may obtain original monitoring resource information corresponding to the monitoring resource request according to the monitoring resource request; the original monitoring resource information may include an original monitoring resource corresponding to the monitoring resource request and original monitoring data for the original monitoring resource.
It should be noted that, because the monitoring resource request generated by the video network terminal may include decoding capability information for the video network terminal, after the monitoring access server receives the monitoring resource request generated by the video network terminal, the monitoring access server may not only obtain corresponding original monitoring resource and original monitoring data according to the monitoring resource request, but also determine whether the decoding capability information of the video network terminal matches with the original monitoring resource information.
Step 202, the video network terminal receives target monitoring resource information sent by the monitoring access server; the target monitoring resource information is the monitoring resource information acquired by the monitoring access server from the transcoder according to the decoding capability information and the original monitoring resource information after responding to the monitoring resource request.
In an embodiment of the present invention, after the video network terminal sends the generated monitoring resource request to the monitoring access server, the monitoring access server may obtain corresponding original monitoring resource data according to the monitoring resource request, and determine whether the decoding capability information of the video network terminal matches the original monitoring resource information; because the monitoring access server is always provided with the transcoder, the monitoring access server can acquire target monitoring resource information through the transcoder according to a judgment result, wherein the target monitoring resource information comprises target monitoring resources and target monitoring data; after the monitoring access server sends the target monitoring resource information to the video network terminal, the video network terminal can play the target monitoring resource.
In an embodiment of the present invention, the original monitoring resource information includes an original monitoring resource and original monitoring data; step 202 may include the following sub-steps:
substep S21, when the decoding capability information matches the original monitoring data, the video network terminal receives target monitoring resource information sent by the monitoring access server; the target monitoring resource information is original monitoring resource information transcoded by the transcoder;
because the hardware transcoder is always hung under the monitoring access server, under one condition, the hardware transcoder can be used for transcoding the original monitoring resource in the original monitoring resource information under the condition that the decoding capability information of the video network terminal is not matched with the original monitoring data to obtain the transcoded original monitoring resource information, namely to generate the target monitoring resource information; after the monitoring access server receives the target monitoring resource information sent by the transcoder, the video network terminal can receive the target monitoring resource information sent by the monitoring access server.
In an embodiment of the present invention, the method for transcoding the original monitoring resource information by the transcoder to obtain the target monitoring resource information may be that the original monitoring resource in the original monitoring resource information is decoded, and then the decoded original monitoring resource is encoded according to the decoding capability information of the video network terminal, where the encoded original monitoring resource is the target monitoring resource; after the target monitoring resource is obtained, the transcoder can generate target monitoring data according to information such as the resolution, the coding format and the like of the target monitoring resource, namely, the original monitoring data is updated to be the target monitoring data; the transcoder can take the target monitoring resource and the target monitoring data obtained after transcoding as target monitoring resource information and send the target monitoring resource information to the monitoring access server; after the monitoring access server sends the target monitoring resource information to the video network terminal, the video network terminal can receive the target monitoring resource information sent by the monitoring access server and play the target monitoring resource.
And a substep S22, when the decoding capability information matches the original monitoring data, the video network terminal receives the original monitoring resource information sent by the monitoring access server.
In an embodiment of the present invention, since the hardware transcoder is always mounted under the monitoring access server, under another condition, the video networking terminal has high performance under the condition that the decoding capability information of the video networking terminal is matched with the original monitoring data, in order to avoid that the video networking terminal with high performance can only receive the transcoded monitoring resource, the monitoring access server may not send the original monitoring resource information received according to the monitoring resource request to the transcoder, i.e. directly send the received original monitoring resource information to the video networking terminal; at the moment, the video network terminal with high performance can directly play the original monitoring resource instead of the monitoring resource transcoded by the transcoder.
In the method for transmitting monitoring resources provided by the embodiment of the invention, after a video network terminal sends a monitoring resource request carrying decoding capability information to a monitoring access server, whether the decoding capability of the video network terminal is matched with the monitoring resource corresponding to the monitoring resource request is judged by the monitoring access server, when the decoding capability of the video network terminal does not meet the monitoring resource, the video network terminal receives the transcoded monitoring resource, and when the decoding capability of the video network terminal meets the monitoring resource, the video network terminal receives the monitoring resource which is not transcoded; by carrying out different code stream conversion according to different decoding capabilities of the video network terminal, the video network terminal with high performance is prevented from only receiving the transcoded monitoring resources, and the high efficiency of the video network terminal in watching the monitoring resources is realized.
Referring to fig. 3, a schematic diagram of an application scenario of the transmission method for monitoring resources of the present invention is shown, in which the involved devices may include an operator-level transcoder, a monitoring access service system, an internet of view, and an internet of view terminal.
As shown in fig. 3, in the application scenario, the process of implementing high efficiency when the video network terminal watches the monitoring resource by using the transmission method of the monitoring resource of the present invention to perform different code stream conversion according to the difference of the decoding capability of the video network terminal may be as follows:
(1) firstly, a video network terminal requests a monitoring access service system to watch monitoring resources, and the request carries decoding capability information aiming at the video network terminal; (2) after receiving the request, the monitoring access service system can pull the monitoring resource corresponding to the request to the device storing the monitoring resource library; (3) when the monitoring access service system pulls the monitoring resource corresponding to the request, whether the monitoring data of the monitoring resource meets the decoding capability of the video network terminal or not can be judged, and if the monitoring data of the monitoring resource meets the decoding capability of the video network terminal, the monitoring resource is directly sent to the video network terminal; (4) if the monitoring data of the monitoring resources do not meet the decoding capability of the video network terminal, the monitoring access service system carries out transcoding according to the decoding capability of the video network terminal carrying out the request; (5) and the monitoring access service system transcodes the monitoring resources through the transcoder and then sends the monitoring resources to the video networking terminal.
In the embodiment of the invention, by adopting the transmission method of the monitoring resource, after receiving the request, the monitoring access service system can control the hardware transcoder to perform code stream conversion according to the decoding capability of the video network terminal so as to meet the requirement that a user watches the monitoring resource, avoid the video network terminal with high performance from only watching the transcoded monitoring resource, and realize the high efficiency of the video network terminal when watching the monitoring resource.
Referring to fig. 4, a schematic diagram of an application scenario two of the transmission method for monitoring resources of the present invention is shown, in the application scenario, the related devices may include an IPC (IP Camera), an NVR (Network video recorder), a hardware transcoder, a monitoring access service system, and a video networking terminal; the IPC and the NVR both have a monitoring resource for shooting, and the two video network terminals connected to the monitoring access service system have corresponding decoding capabilities, where the decoding capabilities refer to capabilities of terminal device hardware for playing videos, such as a capability capable of playing 1080, 2K, or 4K at maximum. It should be noted that, the two video network terminals connected to the monitoring access service system may be terminals with the same type and different decoding capabilities, or terminals with the same type and the same decoding capabilities, or terminals with different types and different decoding capabilities, which is not limited in this embodiment of the present invention.
As shown in fig. 4, when two video network terminals send viewing requests to the monitoring access service system, the decoding capabilities for the two video network terminals are sent to the monitoring access service system at the same time; after the monitoring access server pulls monitoring resources to IPC/NVR according to the watching request, transcoding or no transcoding can be carried out according to the decoding capability of the two video network terminals; and after obtaining the monitoring resource matched with the decoding capability of the terminal, the monitoring access service system sends the monitoring resource matched with the decoding capability of the terminal to the video network terminal.
Wherein, assuming that the resolution of the monitoring resource pulled from the IPC/NVR is 4k, the decoding capability of one of the video network terminals is 1080, and the decoding capability of the other video network terminal is 4k, after the monitoring access service system determines the decoding capabilities of the two video network terminals, because the decoding capability of the 1080 video network terminal is not matched with the resolution of the monitoring resource, the monitoring access service system can send the monitoring resource with the resolution of 4k to the transcoder, the transcoder can transcode the monitoring resource with the resolution of 4k into the monitoring resource with the resolution of 1080, and then send the monitoring resource with the resolution of 1080 after being transcoded to the 1080 video network terminal; because the decoding capability of the 4k video network terminal is matched with the resolution of the monitoring resource, the monitoring access service system can directly send the monitoring resource with the resolution of 4k to the 4k video network terminal.
In the embodiment of the invention, the monitoring access service system can transcode in real time according to the decoding capability of each type of video network terminal, so that the video network terminal with high performance can be prevented from only watching the transcoded monitoring resources, and the monitoring service watching of a user is efficiently met.
