摘　　要：设计并实现了以NexperiaPNX1300Series媒体处理器为核心,集视频、音频、通信、图象和控制为一体的数字多媒体平台.它具有高性能的实时数字信号处理能力,是数字多媒体编解码标准的算法研究与实现的理想平台.实验证明,数字多媒体平台是一个性能卓越、功能强大的实时信号采集与处理系统,完全满足数字多媒体实时处理的需要,它将MPEG 4的视频压缩技术与流媒体技术结合,具有广泛的应用前景.A digital multimedia platform based on Nexperia PNX1300 series and incorporated with video, audio, communication, image and domination is designed and implemented to provide an ideal platform for the study and implementation of standard digital multimedia encoding and decoding algorithm. It is proved by experiment that DMP is an excellent system in collecting and processing realtime signals, and completely satisfies the need of digital realtime processing. Practical examples show that DMP, integrated the video compressing techniques with streaming media technology, is a new generation of interactive steaming media system which has a promising prospect.
