Media Content Review

Huawei Cloud VOD provides content review to detect and filter out pornographic, terrorism-related, and politically sensitive information in media files. In doing so, inappropriate media files can be removed in a timely manner to avoid or reduce the adverse impact.

  • Intelligent review: The review module identifies pornographic, terrorism-related, and politically sensitive content in text, thumbnails, and snapshots. By default, this function is enabled.
  • Manual review: In review details, check the suspected non-compliant media file again. If you confirm the problem, block the media file. Otherwise, approve it.
  • Block: After you block a media file, its status changes to Unpublished. Media files in the Unpublished status can only be previewed on the console and cannot be downloaded or played. The streaming URL referenced by Internet is inaccessible.
