Abstract
A design method of supervisory equipment based on network was introduced.Using ADSP-BF533 embedded CPU produced by ADI Co.
the high speed transmission of video-signal data flow via Parallel Peripheral Interface(PPI) was controlled and the signals were compressed in MPEG-4 mode.Digital video capture
data compression and network transmission were realized.Data transmission is reliable and image is clear in practical applications.
