  • Adaptive bandwidth switching via short-circuitable download
    Patent number: 9300710
    Abstract: Stalling of segment downloads during adaptive bandwidth switching where bandwidth drops in the midst of download of a segment is overcome by downloading segments in multiple subsegments via multiple download operations. Additionally, bandwidth monitoring can be performed in between each subsegment download, and if bandwidth has fallen substantially, and the segment download is not near completion, then the already-downloaded subsegments can be discarded, and the segment download can be restarted from a lower-quality variant.
    Type: Grant
