It was agreed that each group (e.g. Audio) will propose its own structure for its software assets, and that Chairs will send to [e-mail] the contact info of persons that will be in charge of moving, creating, and maintaining the SVN software. In the case of Audio, the Audio Chair should provide to Christian:

• 
  User read-only account on e.g. FhG CVS server
  
• 
  Target structure to use when moving software to MPEG SVN server

Report on corrections for MPEG SAOC

Jonas Engdegård, Heiko Purnhagen, Oliver Hellmuth, Jürgen Herre, Cornelia Falch, Leon Terentiv, Johannes Hilpert, Andreas Hölzer, Werner Oomen

The contribution proposes a number of corrections to the SAOC reference software. In every case it is to align the reference software with the specification text or to defect report on the text.

It was the consensus of the Audio Subgroup to issue the content of the contribution as a Workplan on SAOC Conformance and Reference Software.

Corrections to MPEG Surround reference software

Andreas Hoelzer, Johannes Hilpert, Christian Ertel, Ferenc Kraemer, Leif Sehlstrom, Heiko Purnhagen

The contribution proposes corrections to MPEG Surround reference software. Most proposed corrections have already been integrated into the MPEG Surround reference software. However, the following proposed corrections are not yet integrated:

• 
  Enable differential coding of second (and subsequent) parameter sets in an Independency frame.
  
• 
  Correct handeling of ICC parameter quantiation.
  

It was the consensus of the Audio Subgroup to:

• 
  Issue DoC on DCOR2.2 at this meeting
  
• 
  Issue COR 2 at this meeting with a 2-week editing period
