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： 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： Encoding and decoding a video image having a plurality of frames using a two-step quantization and coding process are disclosed. A block of a frame are encoded by identifying pixels having certain spatial characteristics, forming a second block from the block while replacing the identified pixels with a single pixel value, such as an average of the remaining original pixels. The second block is encoded, such as by transformation and quantization, and placed into a bitstream. The second block is decoded and subtracted from the original block to generate a difference block. The difference block is encoded, such as by quantization, and is placed in the bitstream. At a decoder, both blocks are decoded and combined to reconstruct the original block.
