Filed: 1996-04-24
Abstract: PROBLEM TO BE SOLVED: To make other component portions of a system operate also at the maximum operating frequency of self-checking comparators and thereby to realize a high speed operation of the system, by injecting a pseudo-error into the comparators in a plurality alternately. SOLUTION: A pseudo-error is injected into self-checking comparators 300 and 300' provided in two sets, for instance, alternately by permuters 80 at the same frequency as a pass cycle and in conformity with a prescribed pattern. In a cycle in which an error is injected only into an input signal to the first comparator 300, a function of detecting noncoincidence is checked in the first comparator 300 and, at the same time, it is checked in the second comparator 300' that inputs coincide with each other. In the next cycle, the noncoincidence detecting function of the second comparator 300' and also coincidence of the inputs in the first comparator 300 are checked.  Checking of the function of detecting noncoincidence in the comparators and checking of coincidence or noncoincidence of signals to be compared can be executed simultaneously in this way and, therefore, a high speed operation can be realized.

Title: Blocking effect removal circuit
Inventor: TEI SHIYAKUJIYUN
IPC: H04N19/80
Filed: 1996-04-24
Abstract: PROBLEM TO BE SOLVED: To reduce blocking effects by adding signals outputted from a variable amplifying means and low-frequency component signals outputted from a first filtering means to each other by means of an adder. SOLUTION: A median filter 13 eliminates abruptly changing parts from high-frequency component signals outputted from a low-pass filter 11 by filtering the signals. Control logic 15 and the filter 13 determine a weighted value by utilizing positional information in the block of picture elements constituting encoded video signals and a quantization step size used at the time of encoding the video signals. A variable amplifier 16 amplifies the output signal of the filter 13 by using the weighted value and adds the amplified output signal to the high-frequency component signals outputted from the filter 11. In addition, an adder 18 adds the output signal of the amplifier 16 to the high-frequency component signals outputted from the filter 11.  The amplifier 16 eliminates the discontinuity among the picture elements by outputting signals obtained by amplifying the output signal of a subtractor 14 to an adder 17 based on the weighted value outputted from the logic 15 after adjustment.

Title: Control circuit of reception output
Inventor: FUJIMURA HIROSHI
IPC: H03G3/20
Filed: 1983-06-11
Abstract: PURPOSE:To prevent generation of undesired signal when the input signal is cut off and the reception is started by providing a time constant circuit to the output of a feedback DC amplifier of an AGC circuit and controlling an output control circuit with output signals of a DC amplifier and said time constant circuit. CONSTITUTION:If an input signal (i) applied to a terminal 20 is cut at a time point t1, the output signal ac1 of a DC amplifier 25 varies so that the gain of an AGC amplifier 22 becomes maximum. In this case, the output signal ac2 of a time constant circuit 28 has a slow change compared with the change of the signal ac1. An output control circuit 26 detects that the signal ac1 exceeds the threshold value S1 of the amplifier 25 at a time point t2 and then breaks forcibly a reception signal output circuit 27. Then the reception of the signal (i) is started at a time point t3, and the signal ac2 has a slow change compared with the signal ac1. At a time point t4 the circuit 26 detects that the signal ac2 is lowered less than the threshold value S2 and releases the break of the circuit 27. Thus it is possible to prevent the generation of noises excepting the desired signals when the signal (i) is cut off and in a transient mode obtained when the reception is started.
