摘要:
Methods and devices for reconstructing coefficient levels from a bitstream of encoded video data for a coefficient group in a transform unit. Sign bits are hidden in the parity of partially overlapping subsets of a set of coefficients. This enables the hiding of multiple sign bits per coefficient group. Other information bits may be hidden instead of sign bits in some cases.
摘要:
Encoding and decoding methods are presented that use adaptive reconstruction levels. Reconstruction space parameters are developed by an encoder and inserted in the bitstream with the encoded video data. The reconstruction space parameter may include parameters from which the decoder can determine the levels for dequantization of the encoded video data. The reconstruction space parameters may include a first reconstruction level and a step size between other levels. The first reconstruction level may not equal the step size. In some cases, neither may be equal to the quantization step size used to quantize the transform domain coefficients.
摘要:
Methods of encoding and decoding for video data are described for encoding or decoding coefficients for a transform unit. In particular, the sign bits for the non-zero coefficients are encoded using sign bit hiding. Two or more sets of coefficients are defined for the transform unit and a sign bit may be hidden for each set, subject to satisfaction of a threshold test. The sets may correspond to coefficient groups that are otherwise used in multi-level significance map encoding and decoding.
摘要:
Methods and devices for reconstructing coefficient levels from a bitstream of encoded video data for a coefficient group in a transform unit. Parity hiding is used to signal the parity of the upper left coefficient of the coefficient group. Based on the parity, either the significant coefficient flag or the greater-than-one flag is encoded/decoded for that coefficient, but not both. The greater-than-one flag is encoded/decoded irrespective of whether a maximum number of greater-than-one flags have been encoded/decoded with respect to the other coefficients in the coefficient group.
摘要:
Methods and devices are described for entropy coding data using an entropy coder to encode quantized transform domain coefficient data. Last significant coefficient information is signaled in the bitstream using two-dimensional coordinates for the last significant coefficient. The context for bins of one of the coordinates is based, in part, upon the value of the other of the coordinates. In one case, instead of signaling last significant coefficient information, the number of non-zero coefficients is binarized and entropy encoded.

The present disclosure provides, in part, a priming and boosting vector-based platform to develop vaccines against pathogens that is tailored to elicit a broad T cell response targeting conserved viral epitopes. The universal vaccines are prepared against an immunogen of an infectious pathogenic organism selected from a virus, a bacteria, a fungus or a protozoan comprising at least one ribonucleic acid (RNA) polynucleotide comprising an open reading frame encoding at least one polypeptide antigen or an immunogenic fragment thereof, wherein the polypeptide antigen, or the immunogenic fragment thereof, comprises a conserved internal protein that is enriched in CD8+ T cell recognition antigens. The effectiveness of the priming and boosting platform is tested in a humanized mouse model comprising a fully functional human immune system.

A method for forming a channel layer with high Ge content on a substrate is provided. The method may comprise steps of: preparing the substrate (110), forming a dielectric layer (120) on the substrate (110), lithographing and etching the dielectric layer (120) to form at least one hole in the dielectric layer to grow a channel layer (130) with high Ge content; and growing the channel layer with high Ge content (130) in the at least one hole by a low temperature reduced pressure chemical vapor deposition (RPCVD).
