Reproducing apparatus and additional information providing server system therefor

PURPOSE: A reproducing device and an additional information service server system are provided to supply and receive additional information with respect to contents through a network. CONSTITUTION: An identifier creating unit(11) creates an identifier of contents recorded in a storage media(1). An identifier being created by the identifier creating unit(11) which is an ISRC(International Standard Recording Code) code is read from an optical disc(1) by a reading unit(15) and supplied to the identifier creating unit(11). A network connection unit(13) transmits information to a network or receives information from the network. A browser(14) for searching information stored in an additional information service serve system(100) is mounted in a control unit(12). The browser(14) indicates a user interface for reading a file. The browser(14) transmits/receives information to a server(102) mounted in the additional information service serve system(100). The reading unit(15) reads contents from the optical disc(1). A reproducing unit(16) reproduces contents read by the reading unit(15). An additional information database(101) is provided for making not only contents recorded in the optical disc(1) but additional information with respect to various contents be corresponded to an ISRC code. The server(102) receives an identifier with respect to predetermined contents from the reproducing device(10), extracts additional information corresponded to an identifier from the additional information database(101), and transmits the information to the reproducing device(10).
