Abstract

We present a multifunctional video stream processing peripheral component interconnect (PCI) card based on special digital signal processor (DSP). Real-time processing of the input video signal, such as 3D special effects, mixing graphic caption, making specially transform, and so on, is the core function of the system. The decoded or processed digital video can be compressed into MPEG2 video stream by MPEG2 encoder and captured to the hard disc of computer through PCI bus, and it can be encoded directly as analog or digital output video. Through the PCI bus MPEG2 videos saved on the hard disc can be read out and decoded by the card. Of course the system can transform video signal between analog and digital directly with the analog and digital encoder and decoder. Besides it also supports parallel digital video input and output interfaces. Software control command can be written to the system control module through the PCI multimedia bridge to select exact function of the system. Finally information for writing driver for the PCI card is provided plainly.
