MPEG4 DISC FUNCTION INTRODUCTION

MPEG-4 is the forth video and audio encoding standard released by MPEG (The abbreviation of " Moving 
Pictures Experts Group"). VCD is based on MPEG-1 technology and DVD is based on MPEG-2. MPEG-4 
takes advantage of narrow bandwidth, pursue the best  picture quality by compress and transmit the data in 
frame reconstruct technology. The audio data is compressed by WMA or MP3 standard. MPEG-4 is the most 
advanced compression technology standard in AV field. It has the highest compression rate. By MPEG-4 
technology, we can encode and compress a DVD film into one or two CD-R disc with pretty good picture quality, 
or can burn several films that has same quality as VCD into one CD-R disc, or can burn several films that has 
similar quality to DVD into DVD-ROM disc.

Note: 

  1. The MPEG-4 discs in market now have many different formats, such as XVID, AVI, DIVX, RM etc. But 
  some discs with "MPEG4" logo in market are not encoded by MPEG technology.  It is normal that some of 
  the discs can't be played well in this player because of the incorrect encoding standard.
  2. The MPEG-4 files are displayed as a list in the screen,  choose the icon by the cursors and press "ENTER" 
  button to playback the movie.
