Streaming over the Internet requires a constant and stable connection to play a stream from a remote server. However, the variability of a viewer's Internet connection or streaming playback means that remote playback might not have the quality of media played locally.
Primetime cannot protect from all failures-for example, an ISP failure or a cable disconnection. However, Primetime HLS (HTTP Live Streaming) provides failover protection to protect playback from certain remote server failures and operation failures, making a better experience for viewers. The Adobe Video Engine (AVE) also implements failover protection to provide the least number of playback interruptions and to achieve a seamless playback experience over some remote server turbulence and operational errors in publication. This feature allows the video player to automatically failover to a backup media set when entire renditions or fragments are unavailable.
