A method and system for encoding a segment of an input video with accurate placement of key frames, e.g., I-Frames, using Group of Pictures (GOPs) length for output in a distributed video encoding system with two or more encoders is disclosed. The method includes creating overlapping segments in order to allow precise key frame placement. Further, the method includes using desired segment length and the desired key frame placement to create the overlapping segments. Further, the method includes skipping a certain number of frames at the beginning of the segment, and a certain number of frames at the end of the segment, thereby achieving accurate placement of key frames.

Various of the disclosed embodiments relate to a distributed video encoding or transcoding system may utilize multiple encoding nodes to encode a video sequence by splitting the video into multiple smaller video segments. The assignment of video segments to the encoding nodes is performed to balance the use of the encoding nodes by selecting a node based on its encoding capabilities, e.g., whether the node employed a central processing unit (CPU) based encoding or a graphics processor unit (GPU) based encoding.

A decoder includes a memory storing a map of a space of encoded values. The map includes a plurality of cells partitioning the space, such that each cell encloses a cluster of encoded values and quantizes the cluster of encoded values to a quantized encoded value. Each cell is identified by a label selected from a finite alphabet, such that multiple cells in the map are identified by the same label, and the cells are labeled such that a pair of cells identified by the same label does not share a common boarder. The decoder also includes a receiver to receive from an encoder a label of a cell enclosing an encoded value on the map of the space and a processor to estimate the encoded value using side information to produce an estimation of the encoded value, to select a cell identified by the received label on the map of the multi-dimensional space that is the closest to the estimation of encoded value, and to determine the encoded value as the quantized encoded value of the selected cell.

A method is provided for computing a predicted frame from a first and a second reference frames, the method comprising, for each block of pixels in the predicted frame, the acts of defining a first block of pixels in the first reference frame collocated with a third block of pixels which is the block of pixels in the predicted frame; defining a second block of pixels corresponding, in the second reference frame, to the first block of pixels along the motion vector of the first block from the first to second reference frames; computing a first set of coefficients allowing the transformation of the pixels of the first block into pixels of the second block; computing pixels of the third block using the first set of coefficients and pixels from a fourth block collocated in the first reference frame with the second block of pixels.

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.

A method, computing device and a computer-readable storage medium for encoding and decoding video data for streaming are provided. The method includes receiving video data comprising frames; accessing a dataset comprising at least one image expected to have similarity to at least one of the frames of the received video data; selecting an image or a portion of the image, from the dataset based on similarity to at least a portion of a first frame of the received video data; generating a frame using the image or the portion of the image selected from the dataset; encoding the generated frame and the frames of the received video data to produce encoded video data; and removing data corresponding to the generated frame from the encoded video data to produce modified encoded video data and generating data identifying the image or the portion of the image selected from the dataset.

Methods, systems, and devices for wireless communications are described. A wireless device may receive, from a first source device, a first quantity of frames that may be compressed in accordance with a first compression scheme and may receive, from a second source device, a second quantity of frames that may be compressed in accordance with the first compression scheme. The wireless device may transmit, to at least the first source device, a compression level report that indicates a second compression scheme for compression of additional quantities of frames from the first source device, where the second compression scheme may be associated with reduced processing with respect to processing associated with the first compression scheme, where the reduced processing may be based on a correlation between the first content of the first quantity of frames and the second content of the second quantity of frames.
