Actually, MPEG-3 is the video and audio standard for HDTV broadcasting. This standard should have designed for the compression tech for 20-40 Mbps videos. However, experts found that MPEG-2 is able to do this work and is competent with this job as a matter of the fact. So MPEG-3 was died before it's born. And now MPEG-3 is combined to MPEG-2.
Many people learn about MPEG-3 and then they confused about these two. In fact, we can read MPEG-3 as the third generation of MPEG video and audio standard. Meanwhile, MP3 is part of MPEG-1, Layer 3 of MPEG-1. They belong to different standards.
You can simply consider MPEG-3 as MPEG-2 since there's no MPEG-3 standard any more. If you want to play MPEG-3 videos on mobile devices, do the same thing as playing MPEG-2 videos on mobile devices.
