What is a stream?What is a stream?
A Clip is a complete presentation. If there is more than one component in a clip
(e.g., audio and video) then it is made up of multiple streams.
Each individual stream carries specific information about an element in the
clip. One stream carries the audio elements, one the visual, one the text, etc.
RealPlayer takes each of these streams and synchronizes them so that when the
reporter appearing in your Display Panel opens her mouth the appropriate words
come out.
Content providers often create a clip with a number of streams so that you can
hear and see the best clip your connection can provide. This new ability is
called SureStream.
Because each clip is divided into different streams, RealPlayer optimizes your
experience by choosing appropriate streams created for your current connection
speed, or your connection preferences.
