[Mp4-tech] MPEG4 Audio - regarding MPEG4 BSAC conformance testing

[Zhang, Ying S]

Hi,
I have a question regarding BSAC and its conformance test.
Which documents specifies BSAC and its conformance test?
Is it ISO/IEC 14496-3:2005/Amd 2:2006 and 14496-4:2004?
I shall buy these standard, so better get confirmed before hand.
Thank you!
Best Regards,
 Zhang Ying

Dear Veenit,
In the text of 14496-4: 2004, three kinds of PNS test procedures are
defined (PNS-1/2/3). Please refer to the chapter 5.6.1.2.2.4 in
14496-4:2004.
Regarding BSAC conformance with PNS tool, the 'er_bs07' is for testing
PNS-1 procedure and the 'er_bs08' is for testing PNS-2 AND PNS-3
procedure. So the test criterion is different for each test bitstreams.
Also you can use the 'conf_pns' tool in reference software.
Thanks.
Warm Regards,

Dear All.
I am testing the conformance of my implementation of MPEG4 BSAC decoder,
which has PNS decoding tool implemented in it.
According to ISO/IEC 14496-4:2000(E) Conformance Testing document, the
following is mentioned with respect to testing the PNS tool:
" For all test bitstreams containing PNS data, an energy analysis in
time and/or frequency domain is required ".
My question is:
"To declare a test implementation of PNS tool as conformant do I need to
pass both the spectral as well as temporal conformance, or by passing
either the spectral conformance or the temporal conformance makes my
implementation conformant?"
Thanking you in advance. Awaiting your early reply.
Regards,
Veenit
