broken down into containers and codecs. In some cases the container and
codec are tightly integrated (e.g. MP3) and in some cases very loosly (as in
WAV).
Some example formats:
WAV - many codecs (PCM uncompressed, ADPCM, MP3, uLaw etc)
MP3 (Mpeg-1 Layer 3)
MP4 (Mpeg-4 AAC)
AAC (Mpeg-2 AAC)
WMA
Ogg-vorbis
Monkey Audio
Flac (lossless)
Same story goes for video as for audio, you have containers and codecs.Quote:> c)How video is stored on Hard disk?
> What all video formats are their for storage?
Some containers are limited in what they can store and others (like AVI)
will hold nearly any codec.
Some examples:
AVI - may codecs (Uncompressed YUV/RGB, MP4, MP2, MP1, soon wmv)
MOV - quicktime, many versions
MPG - mpeg-1 or mpeg-2
WMF/WMV - Windows Video
The data format is up to the codec and is codec dependent.Quote:> Here in case of video up to my understanding cideo is store in compressed

I'm not sure I understand the question but I think you're asking if theQuote:> What i could not understand is

format changes if you use a different codec? The answer is not necessarily
if the codec is compatible with a standard container format. For example if
you make some software that works with AVI files, you can use any codec that
is compatible with AVI files but you could not use quicktime.
