Abstract
The utility model discloses a USB video encryption device. The utility model discloses a USB video encryption device inserts the video acquisition encoding device through the USB terminal, receives the audio frequency and video code stream that the video acquisition encoding device transmitted, through the processing of encrypting the unit, to increasing the enciphered message in the audio frequency and video code stream for carry the enciphered message in the audio frequency and video code stream that transmits, pass these back for video acquisition encoding device through black audio frequency and video code stream again, finally in the customer end through the deciphering reduction. Through the utility model discloses a USB video encryption device advances the code stream of transmission and encrypts the back, is the ciphertext mode on the network when transmitting, the security that improves the transmission course. Simultaneously the utility model discloses a USB video encryption device, the power cord of USB terminal is taken from in inside power supply, through the conversion of power switching over unit, no longer need provide the power alone again, facilitates the use.

Along with video coding and decoding technology and the development of network technology, traditional analog transmission video is just being converted into numeral
Transmission.At present conventional audio-video collection encoding device has a high-definition network camera, network hard disk video recorder etc.,
Transmission network includes Ethernet and wireless network etc..Remotely management and monitoring software platform, it is common that be deployed in
The communications equipment room of user, mainly achieves a butt joint into front end audio-video acquisition equipment, the reality of control point, front end video
Time check, control and the configuration to headend equipment, the storage of head end video stream and playback, user management and power
The functions such as limit configuration.There are some new technology and threaten in current open IP technology, particularly closes at some
The safety-protection system at key position, such as bank, the military region, government bodies, transport hub etc..These systems are once quilt
Breaking through, consequence is extremely serious.The system of these key positions, generally image resource is checked, propagate and
Access control and have strict demand, once occur divulging a secret, user itself or country will be had undesirable effect.
Utility model content
The purpose of this utility model is to provide a kind of USB video-encryption device.
