 # Codec Mappings

+A `Codec Mapping` is a set of attributes to identify, name, and contextualise the format and characteristics of encoded data that can be contained within Matroska Clusters.
 
 Each TrackEntry used within Matroska MUST reference a defined `Codec Mapping` using the `Codec ID` to identify and describe the format of the encoded data in its associated Clusters. This `Codec ID` is a unique registered identifier that represents the encoding stored within the Track. Certain encodings MAY also require some form of codec initialisation in order to provide its decoder with context and technical metadata.

 ### Initialisation
 
-Each encoding supported for storage in Matroska MUST have a defined Initialisation. The Initialisation MUST describe the storage of data necessary to initialize the decoder, which MUST be stored within the `CodecPrivate Element`. When the Initialisation is updated within a track then that updated Initialisation data MUST be written into the `CodecState Element` of the first `Cluster` to require it. If the encoding does not require any form of Initialisation then `none` MUST be used to define the Initialisation and the `CodecPrivate Element` SHOULD NOT be written and MUST be ignored. Data that is defined Initialisation to be stored in the `CodecPrivate Element` is known as `Private Data`.
