The batch is an important technique for delivering video over Internet or VoD. It is a key method to improve effect for video multicast. In this paper, we research the batch strategy of proxy cache for streaming media using dynamic cache, proposed the three kind of cache algorithm for proxy cache: window batch, size batch, efficient batch. These methods increased the length of batch, solved the problem for latency time of batch in video muticast, improved the byte-hit ratio of proxy cache for streaming media, and economized the resources of network backbone. Event-driven simulations are conducted to evaluate these kinds of strategy are better than prefix cache and segment cache.
