摘要： 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.

摘要： Systems and methods for enhanced video encoding identify patterns in sequences of raw digital video frames to extract features and identify the type of content represented by the extracted features. The system simulates many outcomes of encoding the sequence of digital video frames by using various different encoding strategies to find the relative best encoding strategy for each sequence of frames. As the encoder processes video, it passes digital video frames to a modeling system which determines whether the video, or video having that same type of content, has been previously observed by the system. The system then selectively applies a saved encoding strategy that had been determined by the system to be particularly suitable for encoding the same sequence of video frames or that same type of content.

摘要： A method and apparatus for optimal signal encoding based on reference data relating encoded-signal characteristics to encoding parameters are disclosed. Reference vectors of encoding parameters and corresponding measurements of encoded-signal characteristics are used to establish a functional relationship between each characteristic and the encoding parameters. Candidate vectors of encoding parameters are identified based on user-defined boundaries of both the encoding parameters and acceptable encoded-signal characteristics. A figure of merit is determined for each candidate vector and the candidate vector of highest figure of merit is presented to an encoder.

摘要： Input data can be losslessly reduced by using a data structure that organizes prime data elements based on their contents. Alternatively, the data structure can organize prime data elements based on the contents of a name that is derived from the prime data elements. Specifically, video data can be losslessly reduced by (1) using the data structure to identify a set of prime data elements, and (2) using the set of prime data elements to losslessly reduce intra-frames. The input data can be dynamically partitioned based on the memory usage of components of the data structure. Parcels can be created based on the partitions to facilitate archiving and movement of the data. The losslessly reduced data can be stored using a set of distilled files and a set of prime data element files.

摘要： Among other things, embodiments of the present disclosure improve the functionality of electronic messaging and imaging software and systems by automating the client-side transcoding of video data based on content. For example, an appropriate transcoding configuration can be selected for video data having complex motion or textures. Accordingly, video quality can be improve when complex motions or textures are present.

摘要： Delta quantized coefficients of a pixel block in a picture in a first representation of a video sequence are encoded based on information derived from estimated quantized coefficients for the pixel block. The delta quantized coefficients represent a difference between actual quantized coefficients of the pixel block derived by encoding at least a portion of the picture in the first representation of the video sequence and the estimated quantized coefficients. The estimated quantized coefficients represent a difference between a reconstructed block of a corresponding picture in a second representation of the video sequence and a prediction block obtained based on intra mode information and/or inter motion information derived by encoding the picture in the first representation of the video sequence.

摘要： Encoded video data representing partial video images is decoded from a first video stream such as a HEVC bitstream. The first video stream comprises video images divided into a spatial array of independently decodable slices. The first video stream comprises network abstraction layer units that each contain video content data for a respective one of the slices preceded by a header that comprises parameters relating to the respective one of the slices in relation to the first video stream. Previously prepared information such as meta data about positions of parameters in the network abstraction layer units or a plurality of different versions of the network abstraction layer units for different partial image sizes (different picture sizes) is used. The meta data may be used for partially rewriting the network abstraction layer units for a subarray of slices, the network abstraction layer units being rewritten at a location selected on the basis of meta data, to make the network abstraction layer units consistent with a second video stream of encoded video data only for the sub-array of slices. Versions of the network abstraction layer units may be selected for the sub-array of slices, from the plurality of different versions. Subsequently, the partial video images are generated by decoding the encoded video data from the rewritten network abstraction layer units.
