What is Compression/ decompression (Codec)?
When we talk about streaming media, we generally are
talking about very large multimedia files which cannot be transferred over
internet without compression.
Compression can be done by applying compression algorithms to data, output
quality and bandwidth should be considered before applying compression
algorithms. Compression is done before sending the media over the internet when
the media is received by the client computer a decompression algorithm will be
applied to decompress the compress data to play the content. These compression
and decompression algorithm are called codecs.
