Abstract
Plural representations of a video stream may be provided. The plural representations may comprise a first chunk, a second chunk, and a transition chunk. The first chunk may comprise a first bitrate and the second chunk may comprise a second bitrate. The first and second chunks may be in decode order starting with an instantaneous decoding refresh (IDR) frame. The transition chunk may be in decode order starting with a non-IDR frame. Next, a request to transition from the first chunk to the second chunk may be received. Then a transition from the first chunk to the transition chunk responsive to the request may occur and the transition chunk may then be provided to another device.
