N2 - An improved system is described for embedding watermarks into video frames in real time using software on an ordinary personal computer. It uses standard video I/O and is separate from the encoding process, so it can be incorporated into various encoding and distributing systems, which makes it well suited for distributing live content. Real-time processing is achieved by making a watermark-pattern generation process common to every frame a pre-process and shortening the watermark embedding time by reusing the watermark pattern output from this pre-process. It is also achieved by storing the watermarked video frames into the 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 demonstrated the validity of this approach.
