A video player for playing a video stream that receives a master playlist identifying at least one variant playlist identifying a video file encoded as a series of video frames that when decoded provide the video stream. The video player based upon a configuration tag in the master play list selectively determining whether the video file is to be processed in a trusted execution environment. The trusted execution environment of the video player selectively includes at least one of (i) hack one, only hack one; (ii) output and link protection; (iii) hardware root of trust; and (iv) forensic watermarking, and decrypts and/or decodes the video stream in such an environment.

A method of processing a sequence of coded video frames conveyed by a digital data stream, where each frame represents an image, includes receiving the sequence of coded video frames at a recording device, determining a frame interval between presentation of an ith coded frame of the sequence and an (i+1)th coded frame of the sequence, calculating a stream time stamp for the ith coded frame, and calculating a stream time stamp for the (i+1)th coded video frame based on the stream time stamp for the ith coded video frame and the previously determined frame interval.

Systems and methods for a self-correcting DVR record pipeline may provider for simpler, lower cost transport producer hardware elements. A free running transport pipeline producer may fill transport buffers without waiting for feedback from the data consumer that data has been completely processed. The pipeline data consumer independently detects transport buffers that are overwritten before processing on the buffer content is complete. The pipeline data consumer drops or deletes any invalid content or stream data to recover from the data overflow condition.

Self correcting record pipeline

A method of modifying a digital data stream composed of a sequence of frames, where each frame represents an image and includes a data field specifying a presentation time stamp value for the frame. If there is a discontinuity in presentation time stamp value between a next frame and a first frame, a value representing a stream time stamp of interest is assigned to a variable for representing the value of the stream time stamp of interest at a point of discontinuity in presentation time stamp, and a value of the presentation time stamp is assigned to a variable for representing the first frame's clock time based on presentation time stamp, and the next frame is stored in a database using as an index the value representing a stream time stamp of interest.
