A storage system and method for media-based fast-fail configuration are provided. In one embodiment, the storage system aggregates elapsed time spent handling errors in parts of a media frame read from the memory of the storage system. The storage system compares the aggregated elapsed time to a threshold representing a total acceptable latency. If the aggregated elapsed time does not exceed the threshold, the storage system handles error(s) in other part(s) of the media frame read from the memory. However, if the aggregated elapsed time exceeds the threshold, the storage system sends an error to a host without handling error(s) in other part(s) of the media frame read from the memory. Other embodiments are provided.

A system for transcoding a digital video stream using a transcoder includes receiving a digital video stream that includes an input video stream and extracting a first set of presentation time stamps from the input video stream which are stored in a table. The system transcodes the input video stream including the first set of presentation time stamps from an initial set of characteristics to a modified set of characteristics including a second set of presentation time stamps that are different from the first set of presentation time stamps. The system processes the second set of presentation time stamps of the transcoded video stream to determine if the second presentation time stamps include jitter, and based upon determining the second set of presentation time stamps include jitter modifying the second set of presentation time stamps based upon the first set of presentation time stamps in the table.

Systems and methods for adaptively adjusting a slew rate of a dejitter buffer in a remote device in a distributed access architecture. The slew rate may be adjusted based on measurements of a fullness state of a buffer made over time. The measurements may be used to calculate a frequency offset value between the rate at which data leaves the buffer relative to the rate at which data enters the buffer and/or used to calculate a current working depth of the buffer. The adaptive slew rate adjustments may be based on the frequency offset value and/or the current working depth.

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.
