Systems and methods for predictive delivery of high bit-rate content for playback
The present disclosure provides for systems and methods for predictive delivery of high bit-rate content. The disclosed systems and methods provide an adaptive-bit-rate streaming (ABS) system with more robust information, thereby allowing more intelligent pre-caching of the media content. By providing greater information to the ABS system, the disclosed systems are able to foresee higher bit-rate segments that require greater attention, allowing the system to use such information to improve the playback experience.
