These days, virtually all audio and video entertainment is digital. Even if you're not enjoying MP3s or videos streamed from the Internet, chances are the music you're listening to or movie you're watching comes from a digital source.
CDs and DVDs are digital media. Satellite TV and satellite radio broadcast digital signals. Most pictures and home movies are shot with digital cameras and camcorders — even over-the-air television is now digital. To get the most out of your entertainment sources, it helps to understand some general concepts about digital audio/video file formats, and how they store information. In addition to this article, be sure to check out our glossary of file formats for descriptions of many of today's widely used formats.
What is a file format, anyway? The way a computer or digital A/V device stores information — any kind of information — is through a series of 0's and 1's.

AAC (Advanced Audio Coding) AAC was developed to improve upon the MP3 audio format, and uses a more advanced form of compression.
According to some listening tests, AAC files encoded at lower bitrates (like 96 Kbps) sound as good or as better than MP3s encoded at higher bitrates (like 128 Kbps) despite their smaller size. The current version of the AAC codec was developed as part of the MPEG4 standard. Versions of AAC are used by Apple in their popular iTunes® Store, as well as Sony in their PlayStation®3 game consoles. Files may appear with the ".m4a" or ".mp4" filename extension. Songs with DRM (digital rights management) purchased from the iTunes Store usually have an ".m4p" extension (with the "p" at the end to denote "protected"). AIFF (Audio Interchange File Format) An audio format for Macintosh operating systems commonly used for storing uncompressed, CD-quality sound (similar to WAV files for Windows-based PCs). Video File Formats. Compression guidelines. Codec - definition.
A codec encodes a data stream or signal for transmission, storage or encryption, or decodes it for playback or editing. Codecs are used in videoconferencing, streaming media and video editing applications. A video camera's analog-to-digital converter (ADC) converts its analog signals into digital signals, which are then passed through a video compressor for digital transmission or storage.
A receiving device then runs the signal through a video decompressor, then a digital-to-analog converter (DAC) for analog display. The term codec is also used as a generic name for a videoconferencing unit. Related concepts[edit] An endec (encoder/decoder) is a similar yet different concept mainly used for hardware. In the mid 20th century, a "codec" was hardware that coded analog signals into Pulse-code modulation (PCM) and decoded them back.
An audio codec converts analog audio signals into digital signals for transmission or storage. Compression quality[edit] Media codecs[edit] See also[edit] How to Master Screencasts in Seven Steps.
