摘要： A method for encoding and decoding a video signal having frames with blocks comprised of pixels. The method reduces the complexity of the video signal to be encoded by applying a filter scheme to the input data stream in an encoder and later reversing the filter scheme in a decoder. A number of filter schemes may be tested to determine the best filter scheme that most reduces the number of distinct color values per color plane. The best filter scheme is used to filter the data to be encoded. Filter information of the best filter scheme is included in the encoded data to enable the decoder to identify the best filter scheme in order to apply the best filter scheme in reverse to re-create the original data stream.

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 method for decoding a stream of encoded video data is disclosed. The video stream includes partitions that have been compressed using lossless encoding. Each partition includes rows that have also been encoded using intra-frame or inter-frame encoding, for example. During the decoding process, two or more of the partitions are entropy decoded on two or more processors in parallel, except that partitions containing adjacent rows in the frame are decoded with an offset so that at least a portion of the output of the entropy decoding of one partition can be used as input in the entropy and intra/inter-frame decoding of the other.

摘要： A method for decoding compressed video information is disclosed. The video information can include a plurality of frames each having a plurality of blocks. The method includes reading from the video information a segment map that associates blocks in the frame with four segment identifiers. Each segment identifier is associated with one or more segment parameters, such as quantization parameters, loop filter type, loop filter strength and sub-pixel interpolation filter. The blocks in each segment are then decoded using the associated segment parameters. Segment parameters can persist to following frames unless overwritten by a subsequent frame. A frame can also include a bit suppressing segmentation, in which case default parameters are used for all blocks in the frame.
