| Abstract: | The MAP CA digital signal processor is a high performance, fully programmable processor developed for various multimedia applications that require real time processing of video, audio, and image data. MAP CA DSP also integrates several peripheral devices on the chip, such as input and output ports for real time video and audio data. For the necessary of video processing in videoconference, the video multipoint process system is designed. It is based on the MAP CA processor and designed as a plug card. It can combine and convert the video bit stream without increasing process burden of PC. |
