Abstract
This invention relates to an apparatus for storing and transmitting AV data. A receiving buffer unit for storing AV data temporarily, a transmitting buffer unit for storing temporarily the AV data to be transmitted, and a primary storage unit for storing AV data and a secondary storage units for storing AV data are connected to each other by means of a subnetwork. A server control unit for controlling the respective units is connected to the subnetwork. Since these units are connected by means of the subnetwork, any restriction is not given to spaces for installing the units. The capacities of the primary and secondary storage units and the transmitting buffer unit are selected so that they become larger in order of the secondary storage unit, the primary storage unit and the transmitting buffer unit. Thereby, the storage units and the transmitting buffer unit are controlled in a hierarchical form. This makes it possible to construct an AV sever system having large capacity and good responsivity with good cost balance.
