【Abstract】 In this motional video surveillance system, MSTFP model is adopted to predict the next-time available bandwidth of CDMA. Based onit, referring to the design of the regulator in H.263 and the XVID codes, the scheme designs an auto-adapted rate-control strategy based on buffercapacity and feedback control. The experiment shows that the video speed and the channel rate obtain a good match, and provides a bettertransmission and display of the video.更多还原
