Abstract
An improved system is described for embedding watermarks into video frames in real time using software running on an ordinary personal computer and that is independent of the parallel-computing platform. It uses standard video I/O and is separate from the encoding process, so it can be incorporated into various types of encoding and distribution systems, which makes it well suited for distributing live content. Real-time processing is achieved by making the watermark-pattern generation process common to every frame a pre-process and by reusing the watermark pattern output from this pre-process. It is also achieved by storing the watermarked video frames into video memory on the video I/O board, thereby eliminating the need for storing them in buffers on hard disk. Testing of a prototype system for standard-definition video demonstrated the validity of this approach.
