Acronyms and initialisms

• Acronyms and initialisms must always be written with capital letters according to the defining standards or specifications. Acronyms and initialisms are types of abbreviations that consist of the first letters of other words and are used as a word in themselves (The difference between acronyms and initialisms is that acronyms can be pronounced as a word, whereas initialisms are pronounced as the separate letters. For example, BIOS and CORBA are acronyms, IP and DVB-2 are initialisms). In case the web interface of a device displays such abbreviations, verify their meaning and correct capitalization.

  E.g. the following table gives an overview of some frequently occurring acronyms and initialisms for transport streams:

  Abbreviation	Description
  CA	Conditional Access
  CAT	Conditional Access Table
  CBR	Constant Bitrate
  CC	Continuity Counter
  DTS	Decoding Time Stamp
  FEC	Forward Error Correction
  LTW	Legal Time Window
  MPTS	Multi Program Transport Stream
  NIT	Network Information Table
  PAT	Program Association Table
  PCR	Program Clock Reference
  PES	Packetized Elementary Stream
  PID	Packet Identifier
  PMT	Program Map Table
  PSI	Program Specific Information
  PTS	Presentation Time Stamp
