Problems solved by technology
Since the NVR processes video data through soft decoding, the clarity of the picture is limited when the NVR is playing video data, especially when the NVR is playing video data from multiple IPCs at the same time, the picture quality is even worse.
[0004] In addition, a very small number of video surveillance systems use the combination of NVR and playback server to monitor the site, and use the playback server to play the video data collected by NVR to improve the picture quality when playing video data. However, due to the combination of NVR and playback The encoding method and development environment of the server are different, resulting in a huge workload. When the video surveillance solution combining NVR and playback server is adopted, the process of transplanting the NVR original program code to the playback server will generate a huge workload.
[0005] To sum up, when the video surveillance system uses the existing technology to monitor the site, the resolution of the video data will be low, and the workload of transplanting the NVR original program code to the playback server is huge, making the scalability poor, etc. problems, therefore, it is very necessary to provide a video surveillance system that can solve the above problems

Embodiment Construction
[0048] Embodiments of the present invention provide a video monitoring method and device, which are used to realize real-time video monitoring through the combination of network hard disk video recorder NVR and playback server, improve the clarity of the screen when the playback server plays video data, and avoid When the playback server installs the NVR, due to the huge workload caused by the different compilation methods and development environments between the NVR and the playback server, the scalability of the system is improved, the original NVR code is reused, and the development cycle is shortened.
[0049] likefigure 1 As shown, the embodiment of the present invention provides a video surveillance method, the method comprising:
[0050] S11, the network hard disk video recorder NVR obtains video data, and converts the video data into real-time streaming protocol RTSP streaming media data;
[0051] S12. The NVR sends the RTSP stream media data to the playback server for...

The invention provides a video monitoring method and device, which are used to realize real-time video monitoring through the combination of network hard disk video recorder NVR and playback server, improve the clarity of the playback server when playing video data, and avoid playback server When installing the NVR, due to the huge workload caused by the different compilation methods and development environments between the NVR and the playback server, the scalability of the system is improved, the original NVR code is reused, and the development cycle is shortened. The method of the invention comprises: a network hard disk video recorder (NVR) acquires video data, and converts the video data into RTSP stream media data; the NVR sends the RTSP stream media data to a playing server for playing.
Description
technical field [0001] The invention relates to the communication field, in particular to a video monitoring method and device. Background technique [0002] Video surveillance systems have been widely used in various places in life. We can monitor the real-time situation at home or workplace through video surveillance systems, effectively preventing accidents from happening and providing protection for our personal and property safety. . [0003] A video surveillance system usually uses a network video recorder (Network Video Recorder, NVR) to perform video surveillance on a site. The working principle of NVR is to store, manage and play the video data transmitted by network camera (IP CAMERA, IPC) equipment in real time, or to store, manage and play video file data. NVR can store, manage and play video data from multiple network camera IPC at the same time. , in order to realize the video monitoring of multiple places; IPC is composed of network coding module and analog ...
