Proposed updates for MPEG Surround conformance sequences

Christian Ertel, Frans de Bont,Ferenc Kraemer
Some of the conformance streams failed to update parameters in the case of Independency Flag equal to 1, and it is proposed to add revised/corrected conformance streams. In addition, it is proposed to clarify the conformance text.

It was the consensus of the Audio Subgroup to incorporate the contribution information into ISO/IEC 23003-1:2007/AMD 1:2008/DCOR 2.

Report on corrections for MPEG SAOC

Oliver Hellmuth, Leon Terentiv, Falko Ridderbusch, Andreas Hölzer
The contribution proposes several corrections:

  • Correction to SAOC text:

    • Currently bsFramingType syntax is incomplete in that this helper variable does not have a default value if it is not transmitted in the bitstream. The contribution proposes new syntax that provides a default value.

    • matrix multiplication is correct.

  • Corrections to Reference Software.

It was the consensus of the Audio Subgroup to

  • Incorporate the contribution information into a DCOR on SAOC text

  • Incorporate the contribution information into a Study on DAM for SAOC Reference Software.

  • Do the DoC on Conformance and Reference Software at the 100th MPEG meeting.
