Hi Jonathan, I assume the new text you propose is "When C is 1, TTID MUST NOT be less than CTID, and TLID MUST NOT be less than CLID; at least one of TTID or TLID MUST be greater than CTID or CLID respectively. That is to say, the target layer index <TTID, TLID> MUST be a layer upgrade from the current layer index <CTID, CLID>. A sender MAY request an upgrade in both temporal and spatial/quality layers simultaneously." I think that this text still only implies the behavior, also the current text talks about upgrade but I assume it is also for a refresh not only to upgrade Maybe " A sender MAY request an upgrade or refresh in both temporal and spatial/quality layers simultaneously by either having C =1 or by having both CLID and CTID with lower values then TTID and TLID. If the sender want to upgrade or refresh only one layer then C MUST be equal to 1 and only the CTID or the CLID of the layer to be upgraded or refreshed should be lower than the TTID or TLID respectively " Roni > -----Original Message----- > From: Jonathan Lennox [mailto:jonathan@xxxxxxxxx] > Sent: יום ד 07 יוני 2017 18:30 > To: Roni Even > Cc: Roni Even; draft-ietf-avtext-lrr.all@xxxxxxxx; General Area Review Team; > avtext@xxxxxxxx; ietf@xxxxxxxx > Subject: Re: Genart last call review of draft-ietf-avtext-lrr-05 > > > > On Jun 7, 2017, at 1:15 AM, Roni Even <roni.even@xxxxxxxxxx> wrote: > > > > Hi Jonathan, > > I did not see the text you added yet as a response to my first > > question So to better clarify my question .
