Panasonic has included its PHL Reference Chroma Processor Plus technology to ensure that image quality is the highest it can be.  The player has a 2.5-hour batter life, rechargeable through any outlet.  A welcome additional feature is the ability to connect the DMP-B15 to any HDTV and use it as a stationary Blu-Ray player.  It can also connect to an HD-audio enabled AV receiver and emit high definition sound to match its video.  And for convenience while it is used as a portable player, it includes an optional headrest mount to allow for hands-free viewing in a car.
