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.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for
the different types of document should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).
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. Details of any patent rights identified during the development of the document will be in the
Introduction and/or on the ISO list of patent declarations received (see www .iso .org/ patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

Clause 3
Replace 3.56 with the following:

domain values
Replace 3.165 with the following:

Replace 3.166 with the following:

In 7.4.4, delete the two sentences:
“When profilePresentFlag is equal to 1 and one or more of these syntax elements are not present, their
values are inferred to be equal to 0. When general_profile_idc is not equal to 10 and is not in the range
of 4 to 7, inclusive, and general_profile_compatibility_flag[ 10 ] is not equal to 1 and general_profile_
compatibility_flag[ j ] is not equal to 1 for any value of j in the range of 4 to 7, inclusive, the value of each
of these syntax elements shall be equal to 0.”
In 7.4.4, after the semantics of general_reserved_zero_34bits, add the following:
general_reserved_zero_7bits, when present, shall be equal to 0 in bitstreams conforming to this
version of this Specification. Other values for general_reserved_zero_7bits are reserved for future use
by ITU-T | ISO/IEC. Decoders shall ignore the value of general_reserved_zero_7bits.
general_reserved_zero_35bits, when present, shall be equal to 0 in bitstreams conforming to this
version of this Specification. Other values for general_reserved_zero_35bits are reserved for future use
by ITU-T | ISO/IEC. Decoders shall ignore the value of general_reserved_zero_35bits.

the same as the syntax elements general_profile_space, general_tier_flag, general_profile_idc,
