The registration descriptor of MPEG-2 transport is provided by ISO 13818-1 in order to enable users of the standard to unambiguously carry data when its format is not necessarily a recognized international standard. This provision will permit the MPEG-2 transport standard to carry all types of data while providing for a method of unambiguous identification of the characteristics of the underlying private data.
ISO/IEC 13818-1:2000 clause 2.6.9 specifies
The 32-bits provides over 4 billion values (4,294,967,296). The initial proposal is to provide four 8-bit ASCII characters
e.g. in hex code,
AC-3 would be: 41-43-2D-33
In binary code,
AC-3 would be: 0100 0001 - 0100 0011 - 0010 1101 - 0011 0011
