[MPEG-OTSPEC] Proposal to discontinue the AdHoc Group

[Levantovsky, Vladimir]

Behdad,

Asking the ISO/IEC SC29 Working Group
> to acknowledge that the AdHoc model has NOT worked for many in the industry
is a strong request, one that cannot be made without providing any substance to support it.

This is especially important when there is a strong evidence to the contrary, that this work has been successfully conducted since 2004, that the OFF standard (ISO/IEC 14496-22) has undergone four editions (in 2007, 2009, 2015, and 2019) and numerous amendments,  and is widely adopted in the industry (see References below). While the WG has been responsible for this work item, the actual work has been done by the AHG.

Can you please elaborate on what, in your opinion, “has NOT worked”? Can you point out to any instance of a technical discussion conducted in this Ad-Hoc Group where a technical objection has been raised that did not receive due consideration and has not been properly reflected in an AHG proposal or recommendation?

Thank you,
Vladimir

Hi,

I like to propose to the ISO WG overseeing this group to acknowledge that the AdHoc model has NOT worked for many in the industry and discontinue this model.

Vlad, can you please add this to agenda for the next meeting of the WG?
