A new KTV set-top box system with the synthesis of video is developed. A new DSP technology is used in this system for the capture and synthesis of audio and video, and the image matting technology is also used for user＇s portrait collection, in order to make the combination of video, audio, dynamic backgrounds, dynamic outlook and the users. To this end, hardware and software are designed for the high-performance DSP- based dual-processor KTV set-top box, and a DSP-based real-time video overlay algorithm, real-time image matting algorithm and window deformation algorithm are also developed. Finally, examples showing the effect of the system are given in the paper.
