Digital media formats: Codecs
versus file containers
Despite international efforts to create standard-based audio and
video formats, many format types are incompatible.
Chapter 9: Specifications
The codec (compressor and decompressor) is the method used to
compress and decompress digital media files. Audio/video
streams usually incorporate two separate codecs: one for the
compressed video and one for the compressed audio. The MPEG
codecs include profiles and levels, which are the minimum
processing requirements for a compliant decoder. Examples of
codecs are:
JPEG: Used by almost all digital cameras to compress digital
images.
MPEG-1, MPEG-2, and MPEG-4: Audio and video codecs
developed by International Standards Technical committees.
VC-1: A video codec developed by Microsoft.
Dolby Digital: An audio codec used in DVD movies and in
high-definition broadcasting.
The file container is the type of file that the digital bit stream is
stored in, regardless of the codec used. File containers have a
specific structure, which helps decoders identify the codecs
necessary for playback. File containers may support multiple
codecs, and they may also include media metadata, DRM (digital
rights management) keys, and other stream-related parameters.
