[Mp4-tech] legality on using test vector names in test report

That's a publicly available spec.  Talk about them all you want.  In fact I think you can make a few thousand CD ROMs containing the conformance spec and the bitstreams themselves and hand them out like candy.  No one will complain.
And there is no need to buy those from ISO.  You can just download them for free from 
http://isotc.iso.org/livelink/livelink/fetch/2000/2489/Ittf_Home/PubliclyAvailableStandards.htm 
The free availability of those bitstreams is totally approved by ISO.

	Gary and all,
	I mean "conformance bitstreams". For MPEG4 these are as defined in the ISO_IEC_14496-4. We bought these from the ISO. 
	My question is "when we publish test report for a codec" it is not sufficient just to say that "Decoder passes all the test vectors from codec committe". In my view a good test report should have the conformance bitstreams names also. Is it legal to put the bitstream names in the report? As bitstream names give out information like
	-- name of the company: mat000.m4v: "mat", nec002.m4v: "nec"
	-- bitstream properties
	Thanks and Regards,
	Neelakanth

		What do you mean by "test vector"?  Where did you get these "test vectors" that you're talking about?

			Dear experts,
			This mail is on legality of using the test vector names. 
			Can we mention the test vector names in the MPEG4 and MPEG2 decoder test report? 
			If no then what are the modalities? Can some body guide me to right set of documents?
			Thanks and Regards,
			Neelakanth
