Abstract

Systems and methods are described to enable synchronized encoding of streaming audio or video content between multiple encoders, in a manner that provides for seamlessly interchangeable encodings. Within a pool of encoders, each encoder can periodically generate state information regarding its state of encoding, and share that state information with other encoders. The other encoders can compare the state information to their current state, to determine whether a desynchronization has occurred. When a desynchronization does occur, such as due to intermittent network packet loss, the encoders within the pool can evaluate the shared state information to determine an authoritative state, and then resynchronize to the authoritative state, resulting in identical or interchangeable encoded content being output from each encoder of the pool.
