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

[Vora, Veenit]

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
