Abstract
A fault tolerant video streaming distribution service utilizes multiple distribution servers to receive and process a video stream simultaneously. Each distribution server performs a mapping of each encoded timestamp associated with a transport stream having time discontinuities to a continuous time sequence. The distribution servers coordinate the timestamp mapping through a distributed leader election protocol that elects a leader to coordinate the timestamp mapping in an environment where failures are anticipated and the number of distribution servers dynamically changes without notice.
