Is there a streaming video codec that can continue playing at a lower quality if the bitstream drops out?

I'm proposing a use that will require a video codec that can drop it's streaming quality and operate on less than half the total quality in a dynamic manner during live streaming if necessary. Basically, the lowest quality video can be streamed with "enhancement" data to increase the quality whereby this enhancement data may be stopped and it could still continue streaming uninterrupted with the lowest or a lower quality stream... Do any of the current formats support such a use? I've investigated WMV's "True Variable Bit Rate" but that seems to refer to the encoding process and nothing more. I'm looking for "VBR streaming" instead! 😀
 
I know that Real's media system will do this for audio, and i'm at least a good 50% sure that it will for video as well.

Peace,
will
 
Yes, the Real has something call 'sure stream' (you check a box when you encode it). It dynamically adjust the bitrates. I am afraid currently nothing in the Open has a similar technology, AFAIK

That would be a good thing if I had the skills to develop my own codecs 😉
