Problems solved by technology
[0004] Although the above method can realize video monitoring, the security is not high, and it cannot be monitored anytime and anywhere
Once someone on the network intercepts video data and knows its encoding format, the acquired data can be saved and spread maliciously, which is a major hazard to the security of the industry; and for professional monitoring systems, only single-screen Monitoring is not enough, it is more practical to support multi-screen real-time monitoring without delay

Embodiment Construction
[0033] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.
[0034] refer to figure 2 , the system for implementing video stream encryption in this embodiment includes a monitoring data acquisition device, a monitoring front-end management subsystem, a monitoring stream processing server, a monitoring management subsystem, and a video playback subsystem, wherein:
[0035] A monitoring data acquisition device for collecting video data and outputting encoded video data;
[0036] The monitoring data acquisition device includes a camera and an encoder, and encodes the video data collected by the camera to the monitoring stream processing server. The encoded data is the output data of the monitoring data acquisition device, and the function of encoding is to compile the video data collected by the camera. The monitoring data acquisition device may also include a pan-tilt and a pan-tilt controller...

The invention discloses a stream media encryption system and method in an industry monitoring system, which provides more secure video monitoring. The system includes: a monitoring data collection device for collecting video data, and inputting the obtained coded video data into the monitoring stream processing server; a monitoring stream processing server for encrypting the received coded video data to obtain streaming media data The monitoring management subsystem is used to send the monitoring link information requested by the video playback subsystem to the video playback subsystem; the video playback subsystem is used to request monitoring from the monitoring management subsystem, and according to the received The received monitoring link information receives streaming media data from the monitoring stream processing server, decrypts it and plays it. The method is as follows: the video playing subsystem receives the encrypted streaming media data and the key, uses the received key to decrypt the streaming media data and then plays it.
Description
technical field [0001] The invention relates to an industry monitoring system, in particular to a system and method for playing monitoring data in the form of streaming media. Background technique [0002] Streaming media technology is an online playback technology that has emerged in recent years. Online playback, as the name suggests, is to play while downloading in real time, instead of waiting for all the content to be downloaded locally before playing, but to play while downloading. Since people can watch real-time continuous audio and video online under low and high bandwidth environments, streaming media technology is widely used in information service fields such as online live broadcast, e-commerce, video-on-demand, and video surveillance. [0003] Existing video surveillance systems such as figure 1 As shown, it includes a video capture device 1, a video management device 2, and a video distribution device 3. After the video capture device 1 captures images, it tr...
