Method provided herein through the above way, computing device have first extracted two kinds of numbers from video data
According to being key frame images and Dynamic Graph respectively, both data can reflect main body cover inner space to a certain extent
Information, and the image quality of both data is all that guaranteed (can not adjust resolution ratio, the clarity energy of image
Access guarantee).Then, it first determines the size of practical network speed value and video data, and then calculates target resolution, it is general next
It says, target resolution is inevitably less than video data original resolution, in order to which video can be quickly sent to
Cloud server.It is preferable to use AVB technologies as transmission technology for method provided herein.
Later if cloud server expects the content of key component (key frame images and target dynamic figure), need
Acquisition request is generated based on time ciphertext and cipher table, is wherein carried in acquisition request in temporal information and request
Hold, and needs to send object code.
Computing device is by a series of verifying to determine whether corresponding information should be fed back to cloud server later
(information i.e. in the first data packet and the second data packet).It should be noted that the purpose of two exit passageways of setting is to improve
Security level, under normal circumstances, the probability that two exit passageways are cracked are lower.And it is possible in computing device to cloud
After server sends content, used exit passageway is just closed, and reopen another exit passageway.
Key frame images are split as the first component and the second component refers to for a complete image being divided into two, the
Complete key frame images can be formed after portion figure and the combination of the second component, can guarantee the safety of key frame images with this
Property.It is similar when sending content and there was only the second data packet, and handle in this manner, Lai Tigao safety.
Due to finally only having sent the first data packet and/or the second data packet, for original video data,
This has been seldom, occupancy network transmission resource that will not be excessive, ensure that transmission rate, also carries out to part and parcel
Retain and transmission, improves the convenience, high efficiency and safety used.
Preferably, method provided herein, further includes:
