摘要:
A pattern-forming method which comprises the following steps: (1) laminating an actinic ray-curable coating film layer onto the surface of an insulating film-forming resin layer. (2) irradiating directly or through a photomask an actinic ray or host wave thereonto so as to obtain a predetermined pattern. (3) subjecting the actinic ray-curable coating film layer to a developing treatment to form a resist pattern coating film consisting of the actinic ray-curable coating film layer, (4) and subjecting the insulating film-forming resin layer to a developing treatment, followed by removing.

The present invention relates to a signal processing apparatus and a signal processing method, an encoder and an encoding method, a decoder and a decoding method, and a program capable of reproducing music signal having a better sound quality by expansion of frequency band.A sampling frequency conversion unit converts a sampling frequency of an input signal, and a sub-band division circuit divides the input signal after the sampling conversion into sub-band signals of sub-bands having the number corresponding to the sampling frequency.A pseudo high band sub-band power calculation circuit calculates pseudo high band sub-band powers based on low band signals of the input signal and coefficient tables having coefficients for the respective high band sub-bands. A pseudo high band sub-band power difference calculation circuit compares high band sub-band powers and the pseudo high band sub-band powers to each other and selects a coefficient table from plural coefficient tables. In addition, a coefficient index which specifies the coefficient table is encoded and set as high band encoded data. The present invention can be applied to an encoder.

A player apparatus for playing an input signal after band-extending the input signal includes: an extension controller to determine an extension start band for the input signal in accordance with information relating to the input signal; and a band divider to divide the input signal into a plurality of sub-band signals. The frequency band is extended on the basis of a plurality of the sub-band signals on a side lower than the extension start band, among the plurality of sub-band signals into which the input signal is band-divided by the band divider.

摘要:
A redundancy control method is disclosed that controls a first redundancy function that switches between a working line and a protection line in response to a detection of a line error and a second redundancy function that performs a path switching in response to a detection of a path error in a ring network operating at a path rate lower than a line rate thereof. The method comprises a step of masking the path error detection within a period from a time of the detection of the line error to an expected time of the detection of the path error.

The present invention discloses a method for controlling a physical bandwidth of a ring-based network by employing a ring application of a data link layer that operates in a physical layer. The method includes the steps of a) requesting each of a plurality of node apparatuses included in the ring-based network to confirm whether the bandwidth can be changed, b) instructing each node of the apparatuses to prepare for the bandwidth change upon receiving a confirmation that the bandwidth can be changed, c) reporting that the preparation for the bandwidth change is completed, and d) changing the bandwidth by using a bandwidth changing function of the ring application upon receiving the report of the completion of the preparation for the bandwidth change.
