Video watermarking prevents illegal copying and distribution by embedding a unique, imperceptible mark or identifier into the video content. This watermark can be a logo, pattern, or sequence of pixels that is overlaid or integrated into the video during encoding. The watermark remains visible or detectable even after the video is downloaded, shared, or manipulated, allowing content owners to trace the source of unauthorized copies.
For example, a broadcaster might use a video watermark to protect its sports event coverage. If someone records the broadcast and uploads it to a piracy website, the watermark can be detected, revealing the original source of the recording. This helps in taking legal action against the pirates and deters others from distributing the content illegally.
In the context of cloud services, platforms like Tencent Cloud offer advanced video processing capabilities that include digital rights management (DRM) and watermarking services. These services help content creators and distributors secure their videos more effectively, leveraging the scalability and reliability of cloud infrastructure.
