Media decryption refers to piracy where an unencrypted media file is sent to a third-party player for unauthorized playback or an encrypted media file is maliciously cracked, and the source content is played back in a third-party player. VOD offers HLS private encryption and commercial-grade DRM, both of which can effectively prevent various cracking behaviors and safeguard media copyrights.

||Teaching and training courses incur high production costs and have high requirements for anti-cracking and anti-piracy.If your courses demand high playback device compatibility, we recommend you use HLS private encryption.
If you need very high security at the expense of the compatibility with some devices, you can consider using commercial-grade DRM.

||TV series are provided by professional copyright holders, and copyright protection is generally a requirement for this type of content.For TV series produced in the Chinese mainland, we recommend you use HLS private encryption.
If a copyright holder outside the Chinese mainland requires DRM protection, we recommend you use commercial-grade DRM.
