A transcoding service is described that is capable of transcoding or otherwise processing content, such as video, audio or multimedia content, by utilizing one or more pipelines. A pipeline can enable a user to submit transcoding jobs (or other processing jobs) into an available pipeline, where a transcoding service (or other such service) assigns one or more computing resources to process the jobs received to each pipeline. The transcoding service and the pipelines can be provided by at least one service provider (e.g., a cloud computing provider) or other such entity to a plurality of customers. A service provider can also provide the computing resources (e.g., servers, virtual machines, etc.) used to process the transcoding jobs from the pipelines.

METHODS AND APPARATUS TO IMPLEMENT SCALABLE VIDEO CODING FOR DISTRIBUTED SOURCE AND CLIENT APPLICATIONS
Methods, apparatus, systems, and articles of manufacture are disclosed that distribute video data encoded with scalable video coding. A remote data source analyzes the graphics system of one or more client device(s), generates a full video frame data and a base-layer video frame, encodes an auxiliary-layer bitstream, and transmits the bitstream to the client device(s). The remote data source does not need to encode or transmit a base-layer bitstream. The client device(s) generates a base-layer frame data, decodes the auxiliary-layer bitstream into an auxiliary-layer frame data, and reconstructs a full video frame based on the second base-layer frame data and the auxiliary-layer frame data. The methods, apparatus, systems, and articles of manufacture disclosed herein save bandwidth by transmitting only the auxiliary-layer bitstream to one or more of the client device(s) without a base-layer bitstream. The client device(s) graphics system is utilized to generate its own base-layer frame data.
Method and System for Distributed Coding of Images
A method for reconstructing an uncompressed signal. The method includes obtaining an encoded signal corresponding to the signal. Obtaining side information about the signal and using the side information to obtain a prediction of dithered linear measurements of the signal. Using the prediction of the dithered linear measurements and encoded quantized dithered linear measurements to obtain quantized linear measurements of the signal based on processing each bitplane iteratively, starting from a least significant level bitplane to a most significant level bitplane. At each iteration, a prediction of each bitplane is formed using the prediction of the dithered linear measurements and the bitplanes processed in the previous iterations. Wherein each code for each bitplane is used to correct each bitplane prediction. Reconstructing the signal as a reconstructed signal using the recovered quantized dithered linear measurements, wherein the steps are performed in a processor of a decoder.

Segment based encoding of video
A distributed video encoding system splits an input video into video segments. The video segments are encoded using multiple video encoding nodes. Prior to the process of splitting the sequence into video segments, the video is analyzed to generate a dependency map. Intelligent segmentation is performed using the dependency map so that each video segment includes all the video frames from which other video frames within that segment have been encoded in the input video. For example, picture headers are inspected to determine the temporal distance of the farthest past and future reference frames used for encoding frames of a video.
