Now it on the network video, is using the standard video, such as MP4 slicing operation, about 10 seconds a ts format of fragments, and then the whole video cutting into hundreds of small files, buffer after the broadcast on the Internet, the general means of encryption, all ts format file using a secret key encryption,
We can use dynamic password and ts video clips combined with encryption, a dynamic password change once per minute, but the roots of the dynamic password secret key is a fixed value, every minute of the dynamic password can use a standard MD5 hash value, which is 256, in this way, the entire video root if you don't know the secret key is unable to direct transcoding, and also can't capture the decoded video streaming,
