Foreword
ISO (the International Organization for Standardization) and IEC (the International Electrotechnical
Commission) form the specialized system for worldwide standardization. National bodies that are members of
ISO or IEC participate in the development of International Standards through technical committees
established by the respective organization to deal with particular fields of technical activity. ISO and IEC
technical committees collaborate in fields of mutual interest. Other international organizations, governmental
and non-governmental, in liaison with ISO and IEC, also take part in the work. In the field of information
technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of the joint technical committee is to prepare International Standards. Draft International
Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication as
an International Standard requires approval by at least 75 % of the national bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights.
Amendment 1 to ISO/IEC 23001-4:2011 was prepared by Joint Technical Committee ISO/IEC JTC 1,
Information technology, Subcommittee SC 29, Coding of audio, picture, multimedia and hypermedia
information.

Part 4:
Codec configuration representation
AMENDMENT 1: RVC-CAL extensions
At the end of Clause 2, add the following paragraph:
DEFLATE Compressed Data Format Specification version 1.3. P. Deutsch, The Internet Society, May 1996.
IETF RFC 1889, RTP A Transport Protocol for Real-Time Applications, H. Schulzrinne, et. al., January 1996.
IETF RFC 2327, SDP: Session Description Protocol, M. Handley, April 1998.
ISO/IEC 14496-12: Information technology– Coding of audio-visual objects – Part 12: ISO Base Media File
Format (technically identical to ISO/IEC 15444-12).

At the end of D.2, add the following paragraph:
Units. Unlike an actor, a unit does not compute anything. A unit is used to declare ‘constants’, ‘functions’, and
procedures that can be referenced or imported into an actor. It cannot contain mutable variables, which would
violate the design constraint that actors do not share state. Units help in factorizing the code in order not to
duplicate function declarations or FU constants.

Replace the title of D.4:
D.4 Structure of actor descriptions
with:
D.4 Structure of actor/unit descriptions

After the title of D.4, add the title D.4.1:
D.4.1 Actor description

In D.4, replace the following paragraph:
Actors are the largest lexical units of specification and translation. The basic structure of an actor is this:
