Knowing bytes really doesn't help you unless you know how relevant those bytes are, also. Are they bytes 'immediately in front of the playhead'? You just don't know. Also, are they 'dense'? Maybe we have 200 kb buffered -- but it's all bytes of the video and none of the audio. Or it's the first 3 seconds, then there is a 10-second gap, and then 4 seconds more. Or, or, or... We really need to define questions that have a clear semantic as to what you are trying to do, I think, that can be correctly and helpfully answered by most or all media systems and for most or all delivery technologies. Consider a system which is playing directly from a DVB stream (e.g. you have a digital radio receiver in your hand-held device). You don't need more than a frame or two buffered, as delivery is exactly real-time and jitter-free. -- David Singer Multimedia Standards, Apple Inc.
