MPEG-1 is a standard estabilished by the Motion Picture Expert Group for medium quality and medium bit rate video.
Generally, the data rate is about 1.5 Mbits/sec for both Video and Audio as this is quite achievable on double-speed CD-ROM drives.
Today, MPEG-1 is primarily aimed at CD-ROM multi-media |

projects where it offers the greatest compatibility in terms of supported computer systems and hardware specifications required for constant playback, especially at 640x480 pixels.
MPEG-1 playback within DVD is limited to the specifications put down originally for VideoCD discs, which were intended to offer comparable runtime to Audio CDs, but with VHS quality video. |
