Problems solved by technology

However, due to the limited computing power of the APU of the network camera, and the APU of the network camera needs to bear the computing tasks generated by most of the software in the network camera when it is running, it may take a lot of time to complete the encryption of the original video, and it is difficult to realize the encryption of the video data. Real-time encryption, resulting in a delay in the video previewed by the user

Abstract

The embodiment of the invention provides a network camera, a video encryption transmission system and a video encryption method. The network camera comprises an application processor used for sendingan AES secret key to an intelligent chip through an encryption channel; the original video data is sent to the network camera intelligent chip through a transmission channel; the network camera intelligent chip is used for encrypting the original video data of the network camera by using the AES key of the network camera to obtain encrypted video data; the encrypted video data of the network camera is sent to a network camera application processor through a network camera encryption channel; and the exchange module is used for providing a network camera encryption channel and a network cameratransmission channel so as to realize data communication between the network camera application processor and the network camera intelligent chip. According to the invention, real-time encryption of the video data can be realized by calling the strong computing power of the intelligent chip under the condition of not increasing the hardware cost, and the time delay caused by video encryption is reduced.

Description

Technical field [0001] The invention relates to the technical field of embedded software systems, in particular to a network camera, a video encryption transmission system and a video encryption method. Background technique [0002] The Internet Protocol Camera (IPC) can send the collected video data to the remote audio and video client (hereinafter referred to as the client) for the user to preview. In order to improve the security of video data transmission between the network camera and the client, the network camera can encrypt the collected video data, and then send the encrypted video data to the client. [0003] In the prior art, the application processor (Application Processing Unit, APU) of the network camera may be based on a local operating system. After the audio and video collection is completed to obtain the original video data, the original video data is encrypted to obtain the encryption Video data. However, due to the limited computing power of the APU of the net...
