In article <1992Sep9.224534.11086@smsc.sony.com> dce@smsc.sony.com (David Elliott) writes: I'll have to admit that I'm not familiar with the deep details of QuickTime, the X Synchronization Extension and other "multimedia" systems, so if this is something already available, then all the better. One of the problems I've seen with multimedia systems is that they provide support for developing "all-in-one" programs, but not really for dealing with multiple synced programs. [rest of original posting deleted -- George] You might check out MAEstro, (I'm the Project Leader). MAEstro is a distributed multimedia authoring environment for Unix boxes, the core of which is an inter-application messaging system built on top of Sun RPC. We are trying to address some of the problems you mention. How successful we are, I'm not sure, but we have learned quite a lot from our experience so far. The MAEstro software (source and binaries) are freely available via anonymous ftp from sioux.stanford.edu, in the directory pub/MAEstro. The full source distribution comes with copious documentation, including a paper presented at the 1991 Summer Usenix conference, and the MAEstro Programmer's Guide which describes in great detail the protocol, semantics, and how we hope to address synchronization problems (in part, at least). The Usenix paper should give you a good technical overview of the environment and the rationale behind our design. If you have any questions beyond that, please feel free to ask me. (Also, ask me about a possible Sony NEWS port; I'm compiling XView 3.0 in the background, as I write this message, on a NEWS laptop running 4.3; the current MAEstro applications were written with the XView toolkit, although the protocol itself is window-system-neutral). I hope this helps some. George P.S.: I just finished a driver for the Vdeck. Nice box. -- ______________________________________________________________________________ George D.
