What is MTV?
MTV is file format supposedly created to allow video playback capabilities on inexpensive Chinese-made portable MP4 players without increasing the cost of those players with the license royalties (and more processor power). These Chinese MP4/MTV Player (sold as “MP4 Player” or “PMP”, for Personal Media Player) are flash-based digital audio players, mostly manufactured in China and capable of displaying images, videos, and text files. Although commonly called MP4 players, are unable to play true MP4 (MPEG-4 AVC H.264) formated videos and are limited to proprietary formats such as this one and AMV.
