An apparatus for encoding/decoding a multichannel signal. The apparatus for encoding/decoding a multichannel signal processes phase parameters for phase information among a plurality of channels constituting the multichannel signal in consideration of the characteristics of the multichannel signal. The apparatus generates an encoded bit stream for the multichannel signal using the processed phase parameters and the mono signal extracted from the multichannel signal.

An apparatus and method for encoding/decoding a multi-channel signal may be provided. The apparatus of encoding a multi-channel signal may insert information about whether to encode a phase parameter indicating phase information of a plurality of channels, included in the multi-channel signal, in a bitstream of the multi-channel signal. The apparatus of decoding a multi-channel signal may determine whether to up-mix a mono signal using the phase parameter based on the information about whether to encode.
摘要:
Provided is a method and apparatus for encoding/decoding an audio signal. Sections which are not used to output noise components near important spectral components and sub-bands which are not used to output noise components, are determined to be encoded or decoded, so that the efficiency of encoding and decoding an audio signal increases, and sound quality can be improved using less bits.

The present disclosure relates to a method for preparing recombinant glycoproteins with high sialic acid content. More specifically, for UDP-GlcNAc 2-epimerase/ManNAc kinase (GNE/MNK) enzyme where point mutation was induced by substituting arginine at position 263 by leucine only or by further substituting arginine at position 266 by glutamine, epimerase activity is constantly maintained, and overexpressed cells thereof experience an increase in intracellular cytidine monophosphate (CMP)-sialic acid content, irrespective of CMP-sialic acid concentration. Particularly, since in an glycoprotein(such as, erythropoietin and thrombopoietin)-producing host cell where point mutationinduced GNE/MNK, human alpha-2,3-sialyltransferase and a CMP-sialic acid transporter gene are simultaneously overexpressed, intracellular content of CMP-sialic acid and sialic acid in glycoprotein increases in cells, overexpression in a host cell producing a sialylated recombinant glycoprotein the three genes above may be useful for preparing glycoprotein with increased sialic acid content.

Method and apparatus for encoding/decoding audio data with scalability are provided. The method includes slicing audio data to correspond to a plurality of layers, obtaining scale band information and coding band information corresponding to each of the plurality of layers, coding additional information containing scale factor information and coding model information based on scale band information and coding band information corresponding to a first layer, obtaining quantized samples by quantizing audio data corresponding to the first layer with reference to the scale factor information, coding the obtained plurality of quantized samples in units of symbols in order from respective symbols formed with most significant bits (MSB) to least significant bits (LSB) based on the coding model information, and repeating, until coding for the plurality of layers is finished. Accordingly, fine grain scalability can be provided with lower complexity and better audio quality even in a lower layer.
摘要:
The present invention relates to an electric circuit having a transformer capable of functioning as a buffer inductor, and a magnetic stimulator using the transformer. The electric circuit of the present invention includes a power supply unit, and rectification means for rectifying current from the power supply unit. A transformer has an inductor on a primary side connected to the power supply unit. A capacitor is connected to an inductor on a secondary side of the transformer. Reverse flow prevention means is connected in series between the capacitor and the transformer to prevent charges stored in the capacitor from reversely flowing toward the transformer. A discharge inductor receives charges stored in the capacitor as discharge current and forms a magnetic field. First switching means turns on or off flow of the discharge current that flows in one direction. Bypass means causes current to flow in one direction.
