摘要： Methods and encoders/decoders for applying in-loop deblocking to intra-coded images/frames. In a decoding context, a deblocking filter is applied to reconstructed pixels of an intra-coded block prior to decoding the subsequent block in the decoding sequence. In an encoding context, a deblocking filter is applied to reconstructed pixels of an intra-coded block in an inter-coding loop before encoding a subsequent block in the coding order for the image.

摘要： A method for encoding an input sequence of symbols as a plurality of codewords including primary codewords and secondary codewords, and a method of decoding the plurality of codewords. The codewords are output as a bitstream including an associated codeword type indicator, which specifies whether its associated plurality of consecutive codewords includes at least one secondary codeword and, if so, the location of the first of the at least one secondary codewords. The decoder selects between a primary codeword decoding tree and a secondary codeword decoding tree, and decodes one of the plurality of codewords using the selected decoding tree.

摘要： Methods and apparatus are provided for secure distribution and storage of data using N channels. An input data sequence, X, is distributed using a plurality, N, of channels. In one embodiment, the input data sequence, X, is split into N subsequences; and the N subsequences are encoded into N bit streams using a set of Slepian-Wolf codes with N separate encoders and a joint decoder. The Slepian-Wolf codes can be selected to ensure a computational complexity to obtain a portion of the input data sequence grows exponentially with respect to a length of the input data sequence unless all of the N bit streams are compromised. In another embodiment, the input data sequence, X, is compressed using a lossless data compressing techniques; and the compressed input data sequence is split into N subsequences that are distributed.

摘要： A video encoder sends at least some information regarding boundary strength to the decoder along with the bitstream of encoded video.

摘要： A method and encoder for entropy encoding image data using a dynamically determined coding order, and a method and decoder for entropy decoding encoded data encoded using a dynamically determined coding order. The coding order for encoding quantized transform domain coefficients is dynamically determined for the image based on at least one characteristic of the quantized transform domain coefficients. The characteristic may be quantization step size if non-uniform quantization is employed for blocks of data.

摘要： The invention discloses an error detection wiring circuit and switching device for instrument transformers in distribution power grid, wherein the wiring circuit integrates a three-phase three-wire metering circuit and a three-phase four-wire metering circuit, and the switching device comprises a linear push rod and a driving motor. Through the control of the driving motor, the movement of the linear push rod to the through terminal ports, which consist of the BN terminal, the CN terminal, and the P1B terminal, is realized. With this, the conversion of the two methods can be realized by simply switching the short circuit wiring of the P1B terminal or the BN terminal to the CN terminal and the AN terminal. Using certain measurement method, each phase of the transformer to be tested can be measured simultaneously, which improves the accuracy of the detected data. Meanwhile, the prior art of wiring conduction structure is changed into a rod-shaped jack-type conduction structure, such that the two-step wiring procedure is reduced to one step during measurement, which can be realized by simply controlling the forward and reverse rotation of the driving motor. No manual wiring operation is required, which is safer and more convenient, and greatly improves the efficiency of wiring conversion during measurement.
