Abstract
A system and method that selects among multiple encodings of the same content to adapt to available bandwidth and meet delay constraints by minimizing the switching lag is disclosed. The system and method include one buffer serving multiple data streams and a switching device. The switching device switches between the multiple data streams and discards data from the buffer that does not belong to a new stream to eliminate switching lag after a switching decision has been made.
