Abstract
The following describes techniques to maintain continuity of a live media stream. A media stream may include a first distribution layer at a first bit-rate with at least one key frame at a first time relative to a time domain and a set of delta frames succeeding the first key frame. The media stream may also include a second distribution layer including at least one key frame at a second time that is shifted in time relative to the first time. A device may subscribe to the media stream with a minimized start-up time and optimized quality of experience among varying complexity of the media content and dynamic network conditions.
