The　intelligent　mobile　video　supervising　system　based　on　DSP　are　introduced　in　this　paper.　Based　on　TMS320DM642　embedded　platform,　video　capture　and　processing　functions　are　designed.　Based　on　streaming　media　technology　and　mobile　communication　technology,　video　relay　and　distribution　functions　are　designed.　Based　on　windows　mobile,　video　monitoring　and　control　functions　are　designed.　With　embedded　and　intelligent　features,　the　system　proves　to　meet　design　expectations.　Embedded　technology　makes　the　system　enjoy　the　advantage　of　compact　size,　high　stability,　strong　mobility　and　application　suitability　in　a　variety　of　environment.　Similarly,　Detection　algorithm　of　moving　objects　based　on　human　morphology　and　linkage　alarm　functions　have　greatly　reduced　the　cost　of　system　and　avoid　the　false　alarm.
