DEFINITIONS:

For the purposes of this Intellectual Property Rights Notice the terms ‘Perceptual Evaluation of Speech Quality Algorithm’ and ‘PESQ Algorithm’ refer to the objective speech quality measurement algorithm defined in ITU-T Recommendation P.862; the term ‘PESQ Software’ refers to the C-code component of P.862. These definitions also apply to those parts of ITU-T Recommendation P.862.2 and its associated source code that are common with P.862.

NOTICE:

All copyright, trade marks, trade names, patents, know-how and all or any other intellectual rights subsisting in or used in connection with including all algorithms, documents and manuals relating to the PESQ Algorithm and or PESQ Software are and remain the sole property in law, ownership, regulations, treaties and patent rights of the Owners identified below. The user may not dispute or question the ownership of the PESQ Algorithm and or PESQ Software.

OWNERS ARE:

  1.  British Telecommunications plc (BT), all rights assigned
    
    to Psytechnics Limited
  2.  Royal KPN NV, all rights assigned to OPTICOM GmbH
    

RESTRICTIONS:

The user cannot:

  1.  alter, duplicate, modify, adapt, or translate in whole or in
    
    part any aspect of the PESQ Algorithm and or PESQ Software
  2.  sell, hire, loan, distribute, dispose or put to any commercial
    
    use other than those permitted below in whole or in part any aspect of the PESQ Algorithm and or PESQ Software

PERMITTED USE:

The user may:

  1.  Use the PESQ Software to:
    

    i) understand the PESQ Algorithm; or ii) evaluate the ability of the PESQ Algorithm to perform its intended function of predicting the speech quality of a system; or iii) evaluate the computational complexity of the PESQ Algorithm, with the limitation that none of said evaluations or its results shall be used for external commercial use.

  2.  Use the PESQ Software to test if an implementation of the PESQ
    

    Algorithm conforms to ITU-T Recommendation P.862.

  3. With the prior written permission of both Psytechnics Limited and OPTICOM GmbH, use the PESQ Software in accordance with the above Restrictions to perform work that meets all of the following criteria: i) the work must contribute directly to the maintenance of an existing ITU recommendation or the development of a new ITU recommendation under an approved ITU Study Item; and ii) the work and its results must be fully described in a written contribution to the ITU that is presented at a formal ITU meeting within one year of the start of the work; and iii) neither the work nor its results shall be put to any commercial use other than making said contribution to the ITU. Said permission will be provided on a case-by-case basis.

ANY OTHER USE OR APPLICATION OF THE PESQ SOFTWARE AND/OR THE PESQ ALGORITHM WILL REQUIRE A PESQ LICENCE AGREEMENT, WHICH MAY BE OBTAINED FROM EITHER OPTICOM GMBH OR PSYTECHNICS LIMITED.

EACH COMPANY OFFERS OEM LICENSE AGREEMENTS, WHICH COMBINE OEM IMPLEMENTATIONS OF THE PESQ ALGORITHM TOGETHER WITH A PESQ PATENT LICENSE AGREEMENT. PESQ PATENT-ONLY LICENSE AGREEMENTS MAY BE OBTAINED FROM OPTICOM.
