Definition
- “A container format is a computer file format that can contain various types of data, compressed by means of standardized audio/video codecs. The container file is used to identify and interleave the different data types. Simpler container formats can contain different types of audio codecs, while more advanced container formats can support multiple audio and video streams, subtitles, chapter-information, and meta-data (tags) - along with the synchronization information needed to play back the various streams together.” (Digital container format (Wikipedia), retrieved 15:56, 20 March 2007 (MET))
