Abstract
A method and system for rendering a HTTP Live Streaming video stream on a display includes a player receiving a master manifest from a network device in response to selecting a video channel. The player also receives a plurality of variant manifests referenced by the master manifest from the network device, where each of the variant manifests references video files each of which having a different bit rate for the same video stream. The player simultaneously maintains the variant manifests in the player. The player determines an effective start time of the video stream based upon the selecting video channel where the effective start time is a time later than an earliest time referenced in the plurality of variant manifests. The player enables reverse of the video stream based upon one of the variant manifests to as early as the effective start time and not enabling reverse of the video stream based upon one of the variant manifests to a time earlier than the effective start time.
