Hi, H263-1998 and H263-2000 use the same packetization. The difference will be in the profile and level optional parameters that are only part of h263-2000 or in the supported annexes as specified in http://www.ietf.org/internet-drafts/draft-ietf-avt-rfc2429-bis-08.txt . So to summarize terminal2 can accept the offer if the optional parameters are compatible with what it supports. Example if the offer is for H263-2000 with no profile (this is baseline) or if there are compatibility in the set of supported annexes. Note that H.263-2000 added the profiles specified in H.263 annex X which a H.263-1998 terminal will not understand. Also there were annexes that were added in the H.263 2000 version Roni Even > -----Original Message----- > From: [EMAIL PROTECTED] [mailto:sip-implementors- > [EMAIL PROTECTED] On Behalf Of Bhat Vimal-A21233 > Sent: Friday, March 10, 2006 2:01 AM > To: [email protected] > Subject: [Sip-implementors] H263-2000 in offer and H263-1998 suported > byremote. > > > Hi All, > > This question is regarding H263-2000 vs H263-1998. > > Suppose Terminal1 supports H263-2000 and the Terminal2 supports > H263-1998. > > When Terminal1 sends an offer with H263-2000 as codec type. > > What shall be the behavior of Terminal2. > > 1) Shall it accept H263-2000 since it is backward compatible with > H263-1998? > 2) or shall it reject H263-2000 codec because Terminal2 supports only > H263-1998? > > > > > Regards, > Vimal > > _______________________________________________ > Sip-implementors mailing list > [email protected] > https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors _______________________________________________ Sip-implementors mailing list [email protected] https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
