Now, more and more manufacturers of Mp3 and Mp4 players are adopting the ROCKCHIP RK26XX series of digital audio-video processing chips from Rockchip. This is a digital multimedia processing chip that supports MPEG-4 video decoding and playback functions, manufactured using 0.18-micron technology. It can be applied in portable MP3 players with MP4 playback functionality.
It features MPEG-4 AVI video playback, MP3/WMA music playback, JPEG image browsing, TXT text reading, voice recording, lyrics display, support for various sound effects including 3D surround sound, compatibility with USB 2.0 High Speed/Full Speed USB functions, radio functionality, display interface, spectrum display, Tetris and Sokoban game functions, multitasking capabilities such as reading e-books while listening to music or playing games while listening to music, firmware upgrades, system language options, and support for multiple storage types including SD cards, Mini SD cards, and MMC cards.
Nowadays, most AVI videos downloaded from the internet cannot be played on Mp3/Mp4 players equipped with Rockchip processors! However, we can obtain more playable AVI files by converting them for use in Mp3/Mp4 players.
