Systems and methods described herein relate to storing and replaying live streaming content. A content recording system may provide virtual manifests to a playback device. The virtual manifests may facilitate a simulation of live streaming of content at a time other than the live streaming. The virtual manifests may be modified versions of the manifests generated during the live streaming of the content. The manifest generation time and location indicators of the content segments are modified to resemble a live stream. If a playback device requests manifests for the live streaming content at a later time, the playback device can display the content at the later time as if the content is being streamed live. This may assist in quality assurance procedures for live stream content.

Method for replaying live video

Systems and methods are described for performing adaptive bitrate (ABR) streaming. A user device may request a segment of a first version of a plurality of versions of a content asset from a content provider, and may receive the segment. An estimated time to receive a second segment of a second version of the content may be determined based on metrics associated with receipt of the segment of the first version and in a manner that takes into account latency with the network, such that a determination whether to switch to a higher or lower bitrate version of a content asset during ABR streaming may be more accurately made.
