Motion picture reproducing middleware selecting/executing device and method

Abstract

Achieved is a motion picture reproducing apparatus at low price (being little increased in price even though the number of specifications are increased) capable of receiving motion picture streams complying with various specifications such as those containing programs that operate on different pieces of middleware, and reproducing motion pictures. A middleware storage unitstores a plurality of different pieces of middleware. Based on program identification information contained in a motion picture stream received by the motion picture reproducing apparatus, an applicable middleware selecting unitselects middleware applicable to a program contained in the motion picture stream. A middleware reading unitreads the selected applicable middleware from the middleware storage unit. A middleware executing unitexecutes the read middleware.
