mp3 Player

A flash based MP3 player, mostly manufactured in China, capable of viewing images, videos, and text files. Although commonly called MP4 Players, they really can't play MP4 format videos. They are limited to proprietary file formats like MTV, DMV, MPV, AMV and similar formats. more...

MTV Video Format

MTV Video format was created with the idea to have some video playback capabilities on inexpensive mp3 player hardware with almost no additional implementation cost.

MTV is a format that will quickly flip through raw image frames while at the same time playing MP3 audio.

The MTV format consists of a file header of 512 bytes length, followed by alternating image and audio frames. While the audio frames are encoded with MPEG2 Audio Layer 3 (aka MP3), the image information is stored in uncompressed raw format, according to the the players display hardware specification.

During decoding of the video stream, the audio frames are passed to the mp3 hardware decoder, while the memory pointer of the display hardware is simply adjusted to the next raw image within the video stream.

While this concept does not require additional hardware for the decoding process, it leads to huge memory requirements as no compression is applied to the image information.

Firmware Updates

The product manual might say something like "go to the website for firmware updates"; but usually, no website is given. Also if you do end up finding the site, it may not have a firmware update for your particular player. Although, many unnofficial websites are hosting firmware updates. If you aren't sure that your hardware is capable with the firmware, don't install it! It could ruin your player for eternity.

65k Color OLED Display

Different from the most common LCD's, most players feature a 65k OLED display. OLED displays don't have as good image quality, but are bright and vibrant.
