The greatest challenge faced by paid video platforms is that some users may download videos in various ways and share or sell them to other platforms without authorization. This severely damages the interests of copyright holders. Unauthorized video recording is the main form of video piracy. Pirates often use screen recording software to record the video, and may even use a camera to directly record their screen, which is hard to prevent.
One of the most effective ways to suppress unauthorized video recording is to track down pirates and combine other means to protect copyrighted content, deter piracy, and demand compensation. VOD's digital watermark feature guarantees a high security level at low costs and helps you easily trace unauthorized video recording.
Traditional countermeasures against unauthorized video recording are to add the viewer's user ID to the video image. There are mainly two methods: adding a common image and text watermark or adding a player floating watermark.
|Common Image and Text Watermark||Player Floating Watermark|
|A watermark covering the video layer during playback in the player. It usually moves like a news ticker on the video image.|
|Common image and text watermark||High: The watermark is encoded to the video and cannot be removed.||High: Each unique user ID watermark needs to be transcoded and stored once.|
|Player floating watermark||Low: The watermark appears in the video player but is not encoded to the video.||Low: It is embedded in the player.|
As shown above, neither of these two types of traditional watermarks can deliver both a high security and a low cost at the same time.
VOD's digital watermark uses an AB stream-based technology.

Submit a ticket to VOD to provide the video obtained in step 4 and the ID of the watermark template created in step 1. The VOD team will extract the
