In this paper, we propose an interactive video–on–demand (VoD) streaming technique using the temporal pattern recognition for an efficient utilisation of video proxy server. The storage management method of video proxy server is based on probabilistic parameters of a Markov model for selective saving of often–used video data. At the first step, the request orders of video data are sequentially identified and the bi–gram transition probability (BTP) of video is calculated using request orders. At the second step, the total probability or base probability is calculated using the created state transition model. Finally, the decision probability is calculated using the video data on the input queue when the storage size is insufficient. If the base probability is lower than the decision probability, we select the video data with the lowest conditional probability as a removal object in order to free up storage space of video proxy server.
