Title: Light link of picture transmission
Inventor: MATSUSHITA SHINICHI
IPC: H04B10/00
Filed: 1984-09-10
Abstract: PURPOSE:To insure the picture quality of chrominance signals R, G and B against deterioration by grouping three chrominance signals R, G and B to one base band, modulating remaining two signals in terms of rectangular two phases and transitting them through one light transmission line. CONSTITUTION:Among chrominance signals R, G and B, the signal G is transmitted by a base band (no modulation). The remaining chrominance signals R and B are multiplexed and transmitted after a carrier signal with the frequency twice or more the maximum frequency of the chrominance signal G is modulated. An oscillator 19 is to generate a carrier signal, which is supplied to an amplitude modulator 22 through an amplitude modulator 21 and 90 deg. phase-shifter 20. The signals R and B, which are amplified and modulated in such a way, are multiplexed with a signal G of the base band in a mixer 25, and transmitted to an electro-optical transfer element 27 through an amplifier 26. Then it is transferred to a light signal by said element 27 and transmitted to the receiving side through one light transmission line.

Title: B8zs pattern detection circuit
Inventor: TOMINAGA NORIMITSU
IPC: H03M5/16
Filed: 1989-07-20
Abstract: PURPOSE:To obtain a B8ZS (violation pattern) detection circuit with a few number of gates by providing a set/reset circuit set at a state outputtable 1 synchronizing with a clock when detecting successive three bits of 0 in input data at a detection circuit and reset when the output of a fifth bit of a shift register goes to 1. CONSTITUTION:A state where the three bits of '0' are continued in the input data is detected at the detection circuit 700, and a corresponding control signal is outputted to the set/reset circuit 900. As a result, the set/reset circuit 900 is set at the state outputtable '1' synchronizing with the clock. Meanwhile, when data stored in the shift register shows '11011', it is outputted with the clock, and is added on a decoder circuit 400. Simultaneously, '1' that is the output of the set/reset circuit 900 is also added. As a result, the decoder circuit 400 detects the fact that the input data is '00011011' i.e., a B8ZS pattern. Thereby, the B8ZS pattern detection circuit with a few number of gates can be realized.
