Title: Low time-delay transform coder, decoder and encoder/decoder for high quality audio and a method for incoding/decoding
IPC: H04B14/04
Filed: 1999-02-02
Abstract: An encoder applies a digital filterbank such as a transform or subband filterbank to an input signal to generate frequency subband information, encodes the resultant subband information using adaptive bit allocation to generate fixed-length values represented by fixed numbers of bits and variable-length values represented by variable numbers of bits, and formats the subband information into an encoded signal in which the fixed-length values are assembled into preestablished positions within the encoded signal. In response to an encoded signal including subband information represented by fixed-length values and variable-length values, a decoder extracts fixed-length values represented by fixed numbers of bits from preestablished positions within the encoded signal, extracts variable-length values represented by variable numbers of bits, wherein the variable numbers of bits are established in response to fixed-length values, and generates an output signal by applying an inverse filterbank to the extracted subband information. <IMAGE>

Abstract: PURPOSE: A reference servo pattern generating method is provided to write or read data on the basis of a servo pattern, which is recorded by a driving apparatus itself, without recording an embedded servo pattern on a record medium. CONSTITUTION: In a reference servo pattern generating method, if a self servo writing operation is requested, a magnetic head is transferred to a position according to corresponding data on the basis of head transfer data which is stored in a ROM(S101,S103). Data remaining on a magnetic disk is deleted(S104), and the magnetic head is returned to an initial position(S105). If the magnetic head is returned to an initial position, a servo pattern stored in the ROM is accessed(S106), and whether an index pulse is generated from a spindle motor is judged(S107). If so, the accessed servo pattern is recorded in synchronization with a frequency generator signal generated from the spindle motor(S108). The recorded servo pattern is read out, and the magnetic head is shifted finely at the same time(S109). Data is read through a head corresponding to the half track shift, and data read through a head, which exists at another plane, is recorded at the same time(S110). Whether servo information is recorded with regard to all regions is judged(S110). If not, the procedure goes to the step(S109). If so, the program is ended.

Abstract: PURPOSE: A method for removing a channel decrease characteristic compensation of a digital subscriber line and an interference between signals are provided for performing a termination in order for a short circuit terminal to have a certain impedance value of a channel in a splitterless ADSL system and installing an inline filter between a telephone set and a telephone line, compensating a channel decrease characteristic. CONSTITUTION: A resistor(102) having a certain impedance value is connected between a ground(GND) and a bridge tap(100) which is a short circuit terminal. When a channel decrease phenomenon occurs by a bridge tap which is a short circuit terminal, a channel decrease characteristic is eliminated based on a termination using an impedance value of a line. The termination of the bridge tap using the characteristic impedance is implemented in such a manner that a load having a characteristic impedance of a line itself is connected with the terminal of the bridge tap.

Abstract: PURPOSE: An exposure method for a thin film transistor array substrate is provided to prevent a misalignment from occurring between patterns in an interface, by performing a double exposure regarding the interface between regions divided for exposure. CONSTITUTION: A display region of an insulating substrate is splitted up into a predetermined number of exposure regions. An exposure process is carried out regarding the respective exposure regions sequentially. A double exposure process is performed regarding an interface of adjacent exposure regions. In the exposure region, two quadrangles having the same size are overlapped as a step type.
