摘要

Client-side Quality-of-Service (QoS) for viewing of Adaptive Bitrate (ABR) streams may be provided. First, a plurality of Adaptive Bitrate (ABR) objects corresponding to a first video rendition of a content program may be downloaded from a Content Delivery Network (CDN) in non-real-time. The plurality of ABR objects may comprise a portion of ABR objects comprising the content program. Next, the plurality of ABR objects downloaded in non-real-time may be stored in a cache. At least a portion of the content program may then be retrieved in real-time using ABR streaming. Retrieving the at least a portion of the content program may comprise obtaining a first ABR object corresponding to the content program and a second ABR object corresponding to the content program.
