VCD stands for “Video Compact Disc” and basically it is a CD that contains moving pictures and sound. If you're familiar with regular audio/music CDs, then you will know what a VCD looks like. A VCD has the capacity to hold up to 74/80 minutes on 650MB/700MB CDs respectively of full-motion video along with quality stereo sound. VCDs use a compression standard called MPEG to store the video and audio. A VCD can be played on almost all standalone DVD Players and of course on all computers with a DVD-ROM or CD-ROM drive with the help of a software based decoder/player. It is also possible to use menus and chapters, similar to DVDs, on a VCD and also simple photo album/slide shows with background audio. The quality of a very good VCD is about the same as a VHS tape based movie but VCD is usually a bit more blurry.

A SVCD can be played on many standalone DVD players and of course on all computers with a DVD-ROM or CD-ROM drive with the help of a software based decoder/player. It is also possible to use menus and chapters, similar to DVDs, on a SVCD and also simple photo album/slide shows with background audio. The quality of a SVCD is much better than a VCD, especially much more sharpen picture than a VCD because of the higher resolution. But the quality depends how many minutes you choose to store on a CD, less minutes/CD generally means higher quality.

WMA (Windows Media Audio) Developed by Microsoft, Windows Media Audio is one of today's most popular 'Net audio formats. Though not as popular as MP3, WMA tends to outperform MP3 in the area of sound quality, particularly with files encoded at lower bitrates like 64 or 96 Kbps. This performance advantage makes it handy for applications like portable digital audio players, where total play time is limited by a finite amount of internal memory. The Windows Media Audio format features built-in copy protection abilities, unlike MP3. Windows® XP, Microsoft's current flagship operating system software, contains native support for WMA encoding, enabling users to create their own WMA music files.

Q. What is MPEG?

This is because MPEG uses very sophisticated compression techniques. Current standards that exist include MPEG-1, MPEG-2, MPEG-3, and MPEG-4. MPEG-1 is a standard for CD-ROM video and audio. MPEG-2 is a standard for full-screen, broadcast quality video. MPEG-4 is a standard for video telephony.

Q. What is RMVB?

IFO file is a DVD information file that stores information about Chapters, Subtitles and Audio Tracks.

Q. What is MP3 ?
