Detailed Description
The technical solutions in the embodiments of the present application will be described clearly and completely with reference to the drawings in the embodiments of the present application, and it should be understood that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Referring to fig. 1, a schematic flow chart of a video transmission method according to a first embodiment of the present invention specifically includes:
step S11: the monitoring equipment collects current video data in real time and detects the current video data to judge whether a preset event occurs.
In order to ensure the safety of citizens, monitoring equipment is arranged in each area to monitor the safety condition of each area. The monitoring equipment records videos of the areas, encodes the recorded videos and uploads the encoded videos to the server in a code stream mode, and the server sends the videos to each monitoring platform, such as a safety monitoring system. Therefore, the condition of the area in the safety control center can be informed in time.
In one embodiment, the monitoring device collects current video data in real time and detects the current video data to determine whether a preset event occurs. For example, the monitoring device detects currently collected video data to determine whether unsafe accidents such as fire, robbery, collapse, etc. occur. Specifically, the monitoring equipment performs feature extraction, feature identification and other processing on image frames in the collected video data, and further determines whether the images have fire, robbery, collapse and other preset events, and if yes, determines that the preset events occur.
Step S12: in response to the occurrence of a preset event, a first network mode currently supported by the monitoring device is detected.
When a preset event occurs, a first network mode currently supported by the monitoring equipment is detected. Specifically, the 5G monitoring device is taken as an example for description, when the 5G monitoring device is installed, internal software of the 5G monitoring device limits the video transmission, and the video is encoded by using the encoding parameters corresponding to the 5G NR mode, so as to obtain a code stream. However, the cellular 5G network may be unstable, for example, the network mode may be changed from the 5G NR mode to the 4G TEL mode, and at this time, the video is still encoded by the encoding parameter corresponding to the 5G NR mode, which may cause the smoothness of the code stream to be insufficient, so that the video sent by the server to the monitoring platform end is blocked. In order to reduce this problem, in the method of this embodiment, when a preset event is detected, a first network mode currently supported by the monitoring device is detected, and the current video transmission data is sent to the server by using a first code stream of video data transmission matched with the first network mode currently supported by the monitoring device. Thereby alleviating the video seizure phenomenon.
Step S13: and sending the current video data to a server by using a first code stream transmitted by the video data matched with the first network mode.
Specifically, the current video transmission data is sent to the server by using a first code stream of video data transmission matched with a first network mode currently supported by the monitoring equipment.
For example, if the first network mode supported by the current monitoring device is the 5G NR mode, the current video transmission data is sent to the server by using the first code stream of the video data transmission matched with the 5G NR mode. At this time, the first code stream sent by the monitoring device to the server may be an ultra high definition code stream, and further, the video data sent by the server to the monitoring platform is ultra high definition video image quality.
And if the first network mode supported by the current monitoring equipment is the 4G TEL mode, transmitting the current video transmission data to the server by using the first code stream of the video data transmission matched with the 4G TEL mode. At this time, the first code stream sent by the monitoring device to the server may be a high definition code stream, and further, the video data sent by the server to the monitoring platform is high definition video image quality.
And if the first network mode supported by the current monitoring equipment is the 2G GSM mode, transmitting the current video transmission data to the server by using the first code stream of the video data transmission matched with the 2G GSM mode. At this time, the first code stream sent by the monitoring device to the server may be a standard definition code stream, and further, the video data sent by the server to the monitoring platform is standard definition video image quality.
The monitoring equipment sends the first code stream to the server, and then sends the current video data to the server, and the server can further send the current video data to the monitoring platform, so that the monitoring platform can play the picture of the monitoring area without blocking, and the condition of the preset event of the monitoring area can be accurately known.
The method of the embodiment can select the first code stream matched with the monitoring equipment for video data transmission according to the network mode supported by the monitoring equipment, and send the current video data to the server by using the first code stream. Therefore, the fluency of the code stream can be improved, the fluency of the video pictures acquired by the monitoring platform can be further improved, and the video pictures are prevented from being jammed.
Fig. 2 is a schematic flow chart of a video transmission method according to a second embodiment of the present invention. Wherein steps S21 and S24 are the same as steps S11 and S13 in the first embodiment shown in fig. 1. The difference is that the present embodiment further includes, after step S21 and before step S24:
step S22: in response to the occurrence of a preset event, the monitoring device issues a communication request to perform voice communication with the monitoring platform.
At present, monitoring equipment with a voice call function is installed and used in many areas, the equipment can trigger the voice call function while transmitting video data, and the voice call function can affect video transmission.
Specifically, a monitoring apparatus having a voice call function is taken as an example for explanation. In this embodiment, when detecting that a preset event occurs in the current video data, the monitoring device triggers a voice call function, sends a communication request to the server, and further enables the server to forward the communication request to the monitoring platform, so that the specific condition of the preset event in the area is reflected to the monitoring platform in a voice mode in combination with a video mode.
Step S23: a first network mode supported by the monitoring device in a voice communication state is detected.
In this embodiment, when a preset event is detected, a voice communication function of the monitoring device is triggered, and a first network mode supported by the monitoring device is detected when the monitoring device is in a voice communication state. Specifically, for example, when the monitoring device is not in the communication state, and it is registered in the 5G NR mode, the current video data may be sent to the server by using the first code stream of the video data transmission matched with the 5G NR mode. When the monitoring device is in a voice communication state, the monitoring device falls back from the 5G NR mode to the 4G LTE mode, and at the moment, the current video data is sent to the server by using a first code stream of video data transmission matched with the 4G LTE mode.
By means of the method, when a preset event occurs, the communication function of the monitoring equipment can be triggered, the network mode of the monitoring equipment under the communication function is detected, and video data transmission is carried out by means of the code stream matched with the network mode. Therefore, the fluency of the code stream can be ensured when the monitoring equipment is in a communication state, the fluency of the video pictures acquired by the monitoring platform is further improved, and the video picture blockage is reduced.
In another embodiment, when the monitoring device is installed, the function of the monitoring device may be initialized, so as to determine the module, the SIM card, and the network mode supported by the operator environment of the monitoring device. In an embodiment, a monitoring device may be used to dial a public telephone, for example, 10086, 10010, and the like, during a call, if the monitoring device is still registered in the 5G NR mode, it indicates that the monitoring device supports the VONR network technology, and if the monitoring device falls back from the 5G NR mode to the 4G LTE, it indicates that the current system does not support the 5G VONR technology, and only supports the 4G LTE technology. That is to say, after the voice call function of the monitoring device is triggered, the video data needs to be encoded by using the encoding parameters corresponding to the 4G LTE technology. By the method, when the preset event occurs, the current video data can be sent to the server by directly utilizing the first code stream of the video data transmission matched with the 4G LTE mode. In another embodiment, it may further be detected whether the network mode supported by the monitoring device falls back from 4G to a 3G or 2G network mode in the communication state, and if so, the current video data is sent to the server by using the first code stream of the video data transmission matched with the 3G or 2G network mode.
Further, in an embodiment, the network mode supported by the monitoring device may be detected at intervals of a preset time period, and then the corresponding video data transmission code stream is selected according to the detection result to transmit the video data. Therefore, the code stream fluency of the monitoring equipment can be ensured in real time, the fluency of the video pictures acquired by the monitoring platform is further improved, and the video picture blockage is reduced.
Further, after the voice communication state of the monitoring device is finished, the third network mode supported by the monitoring device in the non-voice communication state is detected again. And if the third network mode is the same as the first network mode in the voice communication state, continuously utilizing the first code stream (the first code stream is a video transmission code stream matched with the first network mode) to send the video data acquired again to the server. And if the third network mode is different from the first network mode in the communication state, sending the video data acquired again to the server by using a third code stream transmitted by the video data matched with the third network mode.
Fig. 3 is a flowchart illustrating a video transmission method according to a third embodiment of the present invention. Wherein steps S31, S32, and S33 are the same as steps S11, S12, and S13 in the first embodiment shown in fig. 1, except that the embodiment further includes, after step S33:
step S34: and responding to the condition that the preset event does not occur, and acquiring a second network mode supported by the monitoring equipment.
Specifically, if the preset event does not occur, the second network mode supported by the monitoring device may be acquired in a preset time period. It is assumed that the network modes supported by the monitoring device can be detected once every 3 minutes. For example, in 8: 00, detecting the network mode supported by the monitoring equipment to obtain a second network mode supported by the monitoring equipment at the moment; in the following step 8: 03 detects the network mode supported by the monitoring device, and obtains a second network mode supported by the monitoring device at this time.
Step S35: and sending the current video data to the server by using a second code stream transmitted by the video data matched with the second network mode.
Specifically, the current video data is sent to the server by using a second code stream transmitted by the video data matched with the second network mode.
In the method of this embodiment, when a preset event does not occur, the network mode supported by the monitoring device is detected at intervals of a preset time period. The method and the device can ensure that the monitoring equipment can transmit the collected video data by the code stream suitable for the network mode in real time, and further ensure that the code stream transmitted by the monitoring equipment in real time is smooth. The video pause played by the monitoring platform can be further reduced.
Fig. 4 is a flowchart illustrating a video transmission method according to a fourth embodiment of the present invention. In the present embodiment, steps S41, S42, S43, and S44 are the same as steps S21, S22, S23, and S24 shown in fig. 2, except that the present embodiment further includes, after step S44:
step S45: and receiving a parameter adjusting instruction from the server, and detecting a fourth network mode currently supported by the monitoring equipment based on the parameter adjusting instruction.
In this embodiment, after a preset event occurs and the monitoring device is in a voice communication state and establishes a voice communication connection with the monitoring platform, if video data received by the monitoring platform is blocked or has insufficient definition, a parameter adjustment instruction is further sent to the server, the server forwards the parameter adjustment instruction to the monitoring device, and the monitoring device detects a fourth network mode currently supported by the monitoring device based on the parameter adjustment instruction.
Step S46: and sending the currently acquired video data to the server by using a fourth code stream transmitted by the video data matched with the fourth network mode.
And the monitoring equipment transmits the currently acquired video data to the server by using a fourth code stream transmitted by the video data matched with the fourth network mode.
This example is illustrated by: in the following step 8: and 00, when the monitoring equipment detects a preset event, a communication request is sent to establish voice communication connection with the monitoring platform, a first network mode supported currently is detected in a voice communication state, the first code stream of video data transmission matched with the first network mode is utilized, the currently acquired video data is sent to a server, and the server sends the video data to the monitoring platform for video playing. In the following step 8: 05, the monitoring platform finds that the video is blocked, sends a parameter adjusting instruction to the server, the server forwards the parameter adjusting instruction to the monitoring equipment, the monitoring equipment detects a currently supported fourth network mode again based on the parameter adjusting instruction, and sends the currently acquired video data to the server by using a fourth code stream of video data transmission matched with the fourth network mode, and then the video data is displayed on the monitoring platform. In another embodiment, it may be further detected whether the fourth network mode is the same as the first network mode, and if so, it indicates that the video blocking phenomenon is not the network mode, and at this time, the parameter of the code stream may be reduced. For example, if the high definition code stream is obtained by encoding in the first network mode, the standard definition code stream can be obtained by encoding, so as to solve the video blocking phenomenon.
Through the mode of the embodiment, a user can conduct on-site command on-site workers through the monitoring platform and the monitoring equipment.
In an embodiment of the present application, it is assumed that the monitoring device is registered to the 5G network mode at installation. When a preset event does not occur, continuously detecting whether the monitoring equipment supports the 5G network mode or not so as to obtain a second network mode; and if the monitoring equipment currently supports the 5G network mode, the second network mode is the 5G network mode, and the current video data is sent to the server by using a second code stream transmitted by the video data matched with the 5G network mode. When a preset event occurs, detecting whether the monitoring equipment supports the 5G network mode or not, or whether the monitoring equipment establishes voice communication with the monitoring platform or not, and detecting whether the monitoring equipment supports the 5G network mode or not in the voice communication state. And if the 5G network mode is supported, the first network mode is the 5G network mode, and the current video data is sent to the server by using a first code stream transmitted by the video data matched with the 5G network mode. If the monitoring device does not support the 5G network mode, further detecting whether the monitoring device supports the 4G network mode, the 3G network mode or the 2G network mode, and further determining a first network mode currently supported by the monitoring device. When the monitoring device supports the 4G network mode, the first network mode is the 4G network mode, when the monitoring device supports the 3G network mode, the first network mode is the 3G network mode, and when the monitoring device supports the 2G network mode, the first network mode is the 2G network mode. And sending the current video data to a server by using a first code stream of video data transmission matched with the 4G network mode, the 3G network mode or the 2G network mode. Further, the voice communication state of the monitoring device is ended, whether the monitoring device further supports the 4G network mode, the 3G network mode or the 2G network mode in the non-communication state is detected, and then the third network mode is determined. And judging whether the third network mode is the same as the first network mode, if so, encoding the video data acquired again by using the first code stream. And if not, sending the video data acquired again to the server by using a third code stream transmitted by the video data matched with the third network mode.
It should be noted that, in the present application, the first code stream, the second code stream, the third code stream, and the fourth code stream all represent the definition of video data transmission, such as high definition, standard definition, and the like.

Fig. 6 is a flowchart illustrating a video transmission method according to a sixth embodiment of the present invention. Step S61 and step S62 are the same as step S51 and step S52 in the fifth embodiment shown in fig. 5, except that the embodiment further includes, after step S62:
step S63: and sending a parameter adjusting instruction so that the monitoring equipment detects the fourth network mode currently supported by the monitoring equipment based on the parameter adjusting instruction.
Specifically, the picture quality of the video currently played by the monitoring platform is detected, when the picture quality is smaller than a preset value, the parameter adjusting instruction is sent to the server, and the server sends the parameter adjusting direct current to the monitoring equipment, so that the monitoring equipment detects a fourth network mode currently supported by the monitoring equipment based on the parameter adjusting instruction.
Specifically, if the video currently played by the monitoring platform is any one of jammed, flickering and fuzzy, the parameter adjusting instruction is sent to the server, and the server issues the parameter adjusting direct current to the monitoring equipment, so that the monitoring equipment detects a fourth network mode currently supported by the monitoring equipment based on the parameter adjusting instruction.
