What is MP3 and VCD?
WHAT IS MP3?
MP3 is a compression form (like zip). The name MP3 stand for Mpeg1 Audio layer 3 and its compression algorithm is
based on a complicated psycho-acoustic model. This model is based on the fact that the human ear can not hear all the
audio frequencies. The human hearing range is between 20Hz to 20khz and it is most sensitive between 2 to 4 kHz. As
a result the MP3 compression form is destructive, that means the compression algorithm causes the file to lose some
information so that it can not be restored to its original content.
When compressing an audio file (encoding) using the MP3 algorithm you can set the desired encoding level and have any
compression level you want. The larger the compressed file the better the audio quality of the result. The majority of the
files available on the internet are encoded in 128 kbits stereo 44kHz which results in a high quality file that is 12 times
smaller than the original!!! This, of course, has many interesting consequences.
WHAT IS VCD?
Size and shape of any regular music CD with the same digital audio, plus good video capability. It is a new video format
that offers exceptional high-end digital picture quality and smoothness, over an hour of playing time, full CD-quality, stereo
sound, and more. Using MPEG (Motion Picture Expert Group) compression (1:30), VCD’s offer picture quality that is far
superior to the Quicktime movies you see on standard VHS tape.
Notice: When you playback video CD, you must turn PBC OFF in order to stop the chapter/scene.
