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.
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 or www.iec.ch/members_experts/refdocs).
ISO and IEC draw attention to the possibility that the implementation of this document may involve the
use of (a) patent(s). ISO and IEC take no position concerning the evidence, validity or applicability of any
claimed patent rights in respect thereof. As of the date of publication of this document, ISO and IEC had not
received notice of (a) patent(s) which may be required to implement this document. However, implementers
are cautioned that this may not represent the latest information, which may be obtained from the patent
database available at www.iso.org/patents and https://patents.iec.ch. ISO and IEC shall not be held
responsible for identifying any or all such patent rights.
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

related to conformity assessment, as well as information about ISO's adherence to the World Trade
Organization (WTO) principles in the Technical Barriers to Trade (TBT) see www.iso.org/iso/foreword.html.

This document was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology,
Subcommittee SC 29, Coding of audio, picture, multimedia and hypermedia information.
A list of all parts in the ISO/IEC 23090 series can be found on the ISO and IEC websites.

6.6.2.125  Test bitstream BP_SET_C
Specification: Streams with sets of coding tools in Baseline profile.
Functional stage: Test the decoding process of Baseline profile, low delay configuration.
Purpose: Check that the decoder can properly decode bitstreams in which the full set of coding tools is
enabled in Baseline profile, low delay configuration.

6.6.2.126  Test bitstream BP_SET_D
Specification: Streams with sets of coding tools in Baseline profile.
Functional stage: Test the decoding process of Baseline profile, low delay configuration with P slice.
Purpose: Check that the decoder can properly decode bitstreams in which the full set of coding tools is
enabled in Baseline profile, low delay configuration with P slice.

6.6.2.127  Test bitstream ADMVP_I
Specification: Streams with ADMVP is enabled and its dependent tools disabled in Main profile.
Functional stage: Test the decoding process of the inter prediction in Main profile.
Purpose: Check that the decoder can properly decode bitstreams in which ADMVP is enabled and its
dependent tools are disabled in Main profile.

6.6.2.128  Test bitstream ADMVP_J
Specification: Streams with only ADMVP tool enabled in Main profile.
Functional stage: Test the decoding process of the inter prediction in Main profile, low delay configuration
with P slice.
Purpose: Check that the decoder can properly decode bitstreams in which only ADMVP tool is enabled in
Main profile, low delay configuration with P slice.

6.6.2.129  Test bitstream ADMVP_K
Specification: Streams with only ADMVP and its dependent tools enabled in Main profile.
Functional stage: Test the decoding process of the inter prediction in Main profile, low delay configuration
with P slice.
