A system for producing fragmented video content is provided. The system includes a processing device, a non-transitory data store, and a memory storage device having at least a Manifest Processing Service (MPS) unit stored therein. The MPS unit is configured to generate at least one master manifest and store the master manifest in the non-transitory data store, the master manifest comprising a timing reference for a video fragment of the fragmented video content, wherein the timing reference indicates a temporal boundary of processing for the video fragment.

Systems and methods for production of fragmented video content

A playout system for providing playout of fragmented video content is provided. The system includes a non-transitory data store and a processor. The processor is configured to playout content for video origination using a fragmented format. The processor can receive a playlist and generate a plurality of video fragments from source content. A transcoder can process video fragments based on one or more program scheduling requirements from the playlist to generate new video fragments. A manifest is updated to reference the new video fragments. The process can output a video stream based on the new video fragments.

Systems and methods for playout of fragmented video content

A method of video distribution including receiving a manifest including links to blocks, which blocks form at least a portion of a video program, selecting at least some of the links in the manifest, to which auxiliary information is to be added and adding, to each of the selected links, auxiliary information, which does not affect a block referred to by the link. A log of links requested by clients is retrieved from a storage unit, links relating to a specific video program are filtered from the retrieved log, and information on an extent to which the specific video program was viewed, is determined responsive to the filtered links.

Auxiliary information in manifests

A method of providing a video manifest to a client. A router manages, for each of a plurality of ad placement units, a measure of advertisement avails provided by the router to the ad placement unit for filling with advertisements, receives a client request for a video content, and chooses an ad placement unit from the plurality of ad placement units, to select advertisements to be placed in avails of the requested video content, at least partially responsive to the managed measures of advertisement avails. The received client request is directed to the chosen ad placement unit.

Methods and apparatus for delivering video programs are provided. A plurality of video programs are provided in a fragmented, adaptive bit rate format. A request for a respective video program from the plurality of video programs is received from each of a plurality of clients. The requested video programs are multiplexed for delivery to the clients in a multiplex over a shared, fixed-bit-rate transmission channel. In the fragmented, adaptive bit rate format, the fragment delivered to the client may not be the same as the requested fragment and is dependent on multiple criteria, including the bitrate and quality of the requested and delivered fragments, the total available delivery bandwidth, and other fragment requests made on the channel. The resulting multiplex may be either a constant bit rate multiplex or a variable bit rate multiplex.

Managed multiplexing of video in an adaptive bit rate environment

Methods and apparatus for delivering video programs are provided. A plurality of video programs are provided in a fragmented, adaptive bit rate format. A request for a respective video program from the plurality of video programs is received from each of a plurality of clients. The requested video programs are multiplexed for delivery to the clients in a multiplex over a shared, fixed-bit-rate transmission channel. The requests may be for the same or different video programs. The requests for the video programs may occur at the same or at different times. In the fragmented, adaptive bit rate format, the fragment delivered to the client may not be the same as the requested fragment and is dependent on multiple criteria, including the bitrate and quality of the requested and delivered fragments, the total available delivery bandwidth, and other fragment requests made on the channel. The resulting multiplex may be either a constant bit rate multiplex or a variable bit rate multiplex.

Methods and apparatus are provided for combining assets for a streaming video signal. Video assets are provided in an adaptive bit rate format. The video assets may comprise fragments of various types of video content. A stitched manifest identifying a combination of the video assets is created in response to a client request for one or more of the video assets. The stitched manifest is provided to a client and used by the client to request the combination of video assets for playback as one continuous video stream in an order specified by the stitched manifest.

Targeted high-value content in HTTP streaming video on demand

A video stream is transcoded to provide a plurality of primary profiles. Individual frames of the video stream have a Presentation Time Stamp (PTS). A PTS is used as a token to identify particular frames to be encoded as Instantaneous Decoder Refresh (IDR) frames in each profile. An IDR frame period is determined, indicative of a desired number of video frames between two IDR frames. An IDR frame is inserted into each profile every IDR frame period. The IDR frames of each profile are aligned with the same IDR frames of the other profiles. The PTS of each IDR frame in each profile is monitored. Upon determining that a PTS is out of alignment, the next PTS of the affected profile is aligned with the corresponding PTS of remaining profiles. Backup transcoders produce backup profiles that are maintained in alignment with each other and with the primary profiles.
