ITU-T Test Signals for Telecommunication Systems
Conformance and Test Data
Many ITU-T Recommendations contain test signals
intended to test end-to-end quality of telecommunications systems and to assess
implementations conformity to specific Recommendation provisions. These test
data cover the different types of media: audio, still images and moving images.
ITU-T test signals are a highly valuable collection of more than 20 GB size that
constitute a worldwide reference for assessing the different components of
telecommunications systems.
Test signals database
In order to facilitate their use, ITU-T test signals were grouped into a single
database.
Below one may find the list of ITU-T Recommendations that contain freely
available test signals for download. Each link below opens a webpage with a
short description of the relevant content and a link to download the relevant
test signals.
The signals available here constitute part of the corresponding ITU-T
Recommendations and are protected by copyrights laws.
You may use them during product or service development for the purpose of
implementing the corresponding ITU-T Recommendations.
In the downloading section, when applicable, one can preview or hear samples of
the available signal(s).
