A common technique used by broadcast stations for video copyright protection is video logo placement, where a logo indicating ownership is inserted into the video broadcast in a visible way. This paper presents a practical algorithm that performs adaptive video logo placement in TV broadcasts based on a perceptual model from both spatial and temporal perspectives. The algorithm adjusts the position and the transparency of the video logo based on content activity, inter-frame relationships, and contrast with the goal of reducing overall perceptual loss while maintaining logo visibility. The algorithm is computationally efficient and suitable for video logo placement in live broadcasts. Experimental results show that the adaptive video logo placement algorithm achieves a good balance between perceptual quality and logo clarity.
