Bitstream format

A bitstream format is the format of the data found in a stream of bits used in a digital communication or data storage application. The term typically refers to the data format of the output of an encoder, or the data format of the input to a decoder when using data compression.

Standardized interoperability specifications such as the video coding standards produced by the MPEG and the ITU-T, and the audio coding standards produced by the MPEG, often specify only the bitstream format and the decoding process. This allows encoder implementations to use any methods whatsoever that produce bitstreams which conform to the specified bitstream format.

Normally, decoding of a bitstream can be initiated without having to start from the beginning of a file, or the beginning of the data transmission. Some bitstreams are designed for this to occur, for example by using indexes or key frames.

gollark: Teleporting buses *would* be worrying and *could* necessitate Contingency MILLIMETRE EDIFICATION, the dismantling of the UK's public transport systems before the anomaly could spread.
gollark: <@!160279332454006795> HELP I ACCIDENTALYL SAVED A LOW RESOLUTION VERSION ÅAAAAAAAAAA
gollark: Your image reminds me of this.
gollark: Why did you do that? You should have not done that.
gollark: Haskell is actually extremely slow, but it offloads the computing onto infinitely powerful mathematical abstractions to compensate.
