Information reproducing apparatus, authenticating apparatus, and information processing system

Abstract

In this invention, an information recording/reproducing apparatus has an authentication function and directly transfers information to an MPEG board, sub-picture run-length board, speech coding/decoding board without using a main CPU. Thus, information transfer between the information recording/reproducing apparatus and various processing boards can be performed without using a main controller, the load of the main CPU can be alleviated and the main CPU can perform another process during the information transfer period.
