Content protection settings

You can set media encryption and DRM features from the Content protection settings area in the Create channel page. For encryption type and supported devices by media encryption and DRM technology, see the following table.
For more information on other platforms and versions, see Link.

Media Encryption

Media encryption is applied to the HLS protocol and performs encryption on each HLS TS file automatically using the AES-128 method.
The URL to obtain the key is displayed on the manifest. You can use the security token of the CDN to improve your security level.
This feature is an HLS standard feature and is automatically decrypted in players that support HLS.
However, Media Encryption cannot be configured together with FairPlay.

Multi DRM

VOD Station offers Multi DRM, collaborating with INKA Entworks' PallyCon, a content security service validated domestically and internationally, ensuring high performance and stability. Based on the support of standard DRMs, Widevine, FairPlay, and PlayReady, you can apply robust security to videos of your choice without facing the obstacle of incompatible operating systems or platforms.
External DRM can be integrated with Pallycon DRM CPIX API v1, but integration with other providers may not work properly. Only single-key packaging is supported.
