What is MP3 and VCD?

WHAT IS MP3?

MP3 is an audio compression technology. The name MP3 stands for Mpeg1 Audio layer 3 and its compression algorithm is based on a com- plicated 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 and 20kHz and is most sensitive between 2kHz and 4 kHz. As a result, the MP3 compression form is destructive, which means that the compression algorithm causes the file to lose some infor- mation so that it cannot be restored to its original content.

When compressing an audio file (encoding) using the MP3 algorithm, you can set the desired encoding level to obtain any compression level you want. The larger the compressed file, the better the audio playback qual- ity. 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!

WHAT IS VCD?

A VCD is the same size and shape of any regular music CD, and pos- sesses 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.

NOTE:

When you play back a video CD, you must turn PBC OFF in order to stop the chapter/scene.
