ABSTRACT:
While a client reproduces a moving picture, and fast-forward reproducing is carried out in the process of reproducing a moving picture based on a frame, the client transmits a search request to a server. The server searches for the frame of I picture based on a condition in the search request in the fast-forwarding direction (reproducing direction) from the frame. The server uses a search table it has. As a result of the search, the server sequentially extracts frames of I picture and transmits them to the client. The client reproduces the frames every time it receives one of them. Therefore, a network AV system allows the memory capacity of a client to be reduced as much as possible and capable of special reproducing such as fast-forward reproducing and reverse-reproducing.
