A radio frequency signal transmission system is provided which includes a radio frequency signal transmission connector including an antenna for radiating a radio frequency signal having a predetermined frequency band, and a first dielectric body made of a material having a predetermined first permittivity and having the antenna cast therein, and a radio frequency signal transmission cable including a dielectric transmission path formed of a second dielectric body made of a material having substantially the same second permittivity as the first permittivity of the first dielectric body of the radio frequency signal transmission connector. The radio frequency signal transmission connector is connected with the radio frequency signal transmission cable thereby to form a radio frequency signal transmission path through which the radio frequency signal radiated from the antenna is transmitted to the dielectric transmission path via the first dielectric body.

Data having a basic data length of m bits is modulated to a variable-length code having a basic code length of n bits. A sync signal is added to the data after a minimum bit-run in the data. The sync signal exhibits two or more patterns, each pattern breaking a maximum bit-run and having six channel bits for identifying each sync signal. The two or more patterns are distinguished from one another, with a detection distance of at least two therebetween.

Sync signal insertion that breaks a maximum bit-run and has a particular detection distance between two or more sync patterns

A color liquid crystal display device capable of displaying a large color gamut is provided. A color liquid crystal display deviceincludes: a transmissive color liquid crystal panelhaving a color filter and a backlight light source, in which the backlight light sourceincludes a fluorescent lampof large color reproduction range, a color filteris made of color filters of three primary colors that select the wavelength to transmit red light, green light and blue light, and the filter of each color has a spectroscopic characteristic suitable for the spectrum of the fluorescent lampof large color reproduction range.

A digital sync signal added in a modulator to a train of codes having a digital sum value, and detected in a demodulator. The digital sync signal has a pattern that breaks a maximum run and a pattern that preserves a minimum run and a maximum run. The digital sync signal has a bit that is selectively determined to be a '0' or a '1' for controlling the digital sum value of the train of codes. The minimum run is repeated no more than a predetermined number of times irrespective of whether the digital sync signal includes the minimum run.

Data-modulating apparatus, data-modulating method, data-demodulating apparatus, data-demodulating method, and data-providing medium

An apparatus and method for modulating and demodulating data to transmit or record the data on a recoding medium. Data is modulated and demodulated into a variable-length code. The modulated data comprises a sync signal adding means for adding a sync signal to a train of codes after adding a minimum run. The demodulated data comprises a sync signal detecting means for detecting, from a train of codes, a sync signal having a pattern that breaks a maximum run, after detecting a minimum run. A SYNC bit inserting section adds a sync signal to a train of codes, after adding a minimum run, where the sync signal has a pattern that breaks a maximum run.

In order to reproduce data in a stable manner by correction of random and burst errors of a wide range without lowering a transfer speed, Cerror correction for correcting an inter-sector error is carried out in addition to the conventional Cerror correction for correcting an error generated in a sector. The configuration of an error correction unit (or an ECC block) including Cand Ccodes is formed as a track. That is to say, one track is used as the base of an ECC block unit. In this way, two ECC block units never exist in the same track.

Data-recording/reproduction apparatus and data-recording/reproduction method

A data-demodulating method for demodulating a variable-length code (d, k; m, n; r) having a basic code length of n bits to data having a basic data length of m bits. A train of codes is received, and a sync signal having a pattern that breaks a maximum run is detected. The pattern is repeated twice continuously and the minimum run is repeated no more than six times. The first bit of the sync signal is '1' when the train of modulated codes that immediately precedes the sync signal is included in a termination table used to terminate, at a desired position, a code when less than a predetermined number of variable length codes are available.

An encoding method for encoding information bits into a codeword by a linear code is provided. The information bits appear in the codeword as a part of the codeword. The linear code is a code in which a codeword resulting from cyclically shifting an arbitrary codeword by p bit positions is also a codeword. A code polynomial having the codeword in which the information bits appear as a part thereof is computed by executing an arithmetic operation of p polynomials G(x), . . . , G(x) and a polynomial having the information bits as coefficients. Accordingly, a quasi-cyclic (QC) code can be encoded by only polynomial operations, and an encoder can be simplified.
