For example, I have a camera watching a relatively static scene, occasionally the scene changes. I'd like the data rate to drop off when the scene is relatively static and increase to an upper limit when the scene is changing. Sort of semi-constrained. I can imagine hacking into an MPEG encoder engine and modifying it such that if the motion estimation is below some threshhold nothing comes out. Anything like this already exist? -- Brian Litzinger
