Abstract

A content selectable reproduction system is disclosed. A content reproduction unit having a display function of a built-in or external display device includes a content reproduction section which reproduces content, an operation section which issues an operation command, and a first control section which inputs the operation command and controls the content reproduction section according to the operation command. A portable reproduction unit control apparatus connected to the content reproduction unit through a first connection section includes a display control section and a second control section which exchanges control signals with the first control section through the first connection section. A portable reproduction unit connected to the portable reproduction unit control apparatus through a second connection section includes a storage medium storing content data files and content management data with which the content data files are managed, a reproduction section reproducing the reproduction content files, and an operation section.
