From manufacturer: This high-speed, high-precision circuit converts DVD video signals using 4-times oversampling for progressive scan playback and 8-times oversampling for interlace scan playback. The high-density conversion process results in clear, beautiful pictures with high resolution and high S/N ratio. DVD-S48 lets you enjoy photos (JPEG) and music (MP3) saved into USB memory. The narrow width allows the player to fit neatly onto a TV rack. Packaging materials are also more compact and lighter, to reduce both transportation costs and CO2 emissions.
