摘要： Disclosed herein are systems, methods, and apparatuses for selecting different coding parameters for different portions of a video frame or image to be transmitted or stored for later decoding. The coding parameters for a particular portion of a video frame or image are selected according to their distance from a selected point of interest, where the parameters can be selected to alter the tradeoff between transmission bandwidth and perceived image quality to preserve image quality in areas designated as high interest while saving transmission bandwidth for areas designated as having less interest. Also disclosed are associated systems, methods, and apparatuses for decoding such encoded video frames or images.

摘要： Techniques for efficient coding of video content are presented. When encoding motion vectors of a current block of a current video frame, a coder management component analyzes encoded blocks of the current frame adjacent to the current block and encoded blocks of the previous video frame that occupy locations in the previous frame corresponding to the locations of the current block and blocks adjacent to the current block. The coder management component arranges motion vectors in order as a function of spatial proximity, temporal distance between the previous frame and the current frame, and/or motion vector magnitude. The coder management component selects a coding mode, based on the order, to transmit to the decoder. A coder component encodes the current block using the motion vector associated with the coding mode.

摘要： Video data streams can be encoded and decoded using inter or intra prediction. The blocks of a frame can be divided into groups of blocks to be inter predicted and blocks to be intra predicted, and the blocks to be inter predicted are encoded first. The availability of data from the inter predicted blocks can improve the performance of intra prediction over processing the blocks in the scan order since more pixel data is available for intra prediction of some blocks. For example, when the scan order is raster scan order, intra prediction of a block can use pixels peripheral to the bottom and right sides of the block in addition to the pixels peripheral to the top and left sides of the block.

摘要： Techniques for delivering content, such as videos, over a network are described. A core server and an edge server are provided. The core server has local storage. The edge server has local storage. A set of video frames is partitioned into a first group and a second group. Video frames in the first group are encoded into a scalable encoded stream. The scalable encoded stream is sent to the local storage at the edge server. The second group of video frames is encoded into a set of supplemental encoded streams using the scalable encoded stream as a reference. The supplemental encoded streams are encoded such that the bit rate and/or resolution of any two supplemental encoded streams is different. The set of supplemental encoded streams is stored in the storage of the core server.

摘要： A frame of a video stream is segmented based on its ability to predict the contents of one or more temporally nearby frames. Predictive ability can be measured by comparing the magnitude of the error per block of a video for intra-frame prediction with inter-frame prediction. Segments can be determined by grouping similar error magnitudes together when the frame is a good predictor for the nearby frames. Coding parameters can be defined at the segment level to reduce the number of bits used to represent the encoded video stream and thereby reduce network and/or storage bandwidth.
