摘要： To better handle the flat tail phenomenon commonly seen in transform coefficients such as DCT coefficients, a system and method having a model dubbed a transparent composite model (TCM) are described. Given a sequence of transform coefficients, a TCM first separates the tail of the sequence from the main body of the sequence. A first distribution such as a uniform, truncated Laplacian, or truncated geometric distribution can be used to model transform coefficients in the flat tail while at least one parametric distribution (e.g. truncated Laplacian, generalized Gaussian (GG), and geometric distributions) can be used to model data in the main body. A plurality of boundary values can be used to bound a plurality of distribution models. The plurality of boundary values and other parameters of the TCM can be estimated via maximum likelihood (ML) estimation or greedy estimation.

摘要： Devices and methods for entropy decoding a bitstream of encoded data by extracting a plurality of encoded subsequences from a payload field of the bitstream for parallel decoding on a set of parallel entropy decoders. The method includes dividing the payload of concatenated encoded subsequences into segments using a distribution function and distributing the segments amongst the set of parallel entropy decoders to balance the computational load among the parallel entropy decoders. The received bitstream includes auxiliary information inserted by the encoder to enable the decoder to entropy decode segments that begin with a portion of an encoded subsequence.

摘要： A method of encoding a video using constrained soft-decision quantization. The soft-decision quantization includes first performing hard-decision quantization to obtain hard quantized coefficients and, then, obtaining a soft quantized coefficient using a rate-distortion calculation over a search range of quantization levels for a transform domain coefficient, wherein the search range of quantization levels for that transform domain coefficient is constrained within a number of quantization levels of a corresponding hard quantized coefficient. The search range may be based upon a fixed threshold, the coefficient position, the hard quantized coefficient magnitude, a threshold value less accumulated distortion, or other factors, including combinations of these factors. The accumulated distortion may be measured by an L1 norm.

摘要： Methods and systems for automatically and efficiently categorizing, securely transmitting, and managing multimedia contents generated from a network connection enabled digital data generating device by way of multimedia transcoding, compression, and/or classification. Content similarity between multimedia data units with one unit corresponding to one image, one video frame, or one audio frame is first detected and identified, and then used to help encode conditionally one unit given another. Based on the identified content similarity and/or the resulting compression efficiency, these multimedia units are automatically categorized in terms of their contents along with their locations, occasions, events, and/or features. Whenever network connections selected by a user are available, these encoded and categorized multimedia data units along with their metadata containing side information including their locations, occasions, events, features, and other information specified by the user are then automatically and securely transmitted to networks, cloud servers, and/or other network connected devices.
