Abstract
Methods and systems for switching between media streams can use a comparison of an average bandwidth for a new stream to an observed bit rate for an existing stream in order to determine whether to switch to the new stream. A check on the amount of data buffered for the existing stream can also be performed in order to determine whether a system should switch to the new stream.
