Abstract
Techniques for synchronizing streams in an adaptive streaming environment include cross-chassis and intra-chassis synchronization of video and/or audio. In an adaptive streaming system that streams content in segments or chunks at varying levels of quality corresponding to different coding rates, implementations enable seamless switching between output streams. For example, synchronizing multiple output streams for switching between coded adaptive bit rate streams across multiple chassis involve calculating an NTP/UTC offset.
