This proposal for work on a common RDC protocol is submitted to the Q3 meeting next week in Colorado Springs. I uploaded it to: ftp://ftp.imtc-files.org/imtc-site/incoming/Common_RDC_Proposal.zip

Summary:
This proposal continues the work of recent RDC audio conferences and the Q11-14/16 meeting in Cannes. The proposed approach is to use a common RDC protocol (V.RDC) which can be carried within a T.120 APE (T.RDC) or without T.120 (H.RDC) in an H.245 logical channel. H.323 systems will use H.RDC for both point to point and multipoint, with T.RDC being optional.
This paper includes the following:
- suggestions for separating the common protocol from the T.120 specifics, in the current T.RDC (ftp://www.imtc.org/imtc-site/T120-top/t120_ky98/TRDCreva.doc). - changes to camera control to make it H.281 compatible - start/continue/stop - predefined device identifiers - presets - changes to camera control to make it more useful and usable - automatic pointing - coordinates in terms of field of view rather than degrees - a list of work still to do in defining the ASN.1 syntax for H.RDC
