Abstract: PURPOSE:To reproduce a still picture efficiently by providing field memory, an interpolator circuit, a selection circuit, a reproduction mode specifying switch and a signal generator circuit and by selecting a field still picture reproduction and a frame still picture reproduction. CONSTITUTION:A still picture signal of a field memory 1 is supplied to an adder 2 and a one-hour delay circuit 3, and an output of the circuit 3 is transmitted to one input terminal 5A of a selection circuit 4 and the adder 2. An output of the adder 2 is transmitted to the other input terminal 5B of the circuit 4 through an 1/2 coefficient multiplier 5. Here, a switch 16 for specifying a field still picture reproduction and a frame still picture reproduction is provided. When the switch 16 specifies the field still picture reproduction, the circuit 4 selects an input of the terminal 5A, and when the frame still picture reproduction is specified, the circuit 4 is caused to select alternately the inputs of the terminals 5A and 5B at every field. A control signal of the circuit 4 is generated in a signal generator circuit 14.

Abstract: PURPOSE:To enable excellent recording even with slower tape running speed, by shifting either one of the phases of the output signal of the third power circuit and the recording signal to another, and feeding those signals to the magnetic head after superposition. CONSTITUTION:The recording signal from the input terminal 11 is fed to the phase delay circuit 13 via the recording equalizer circuit 12, a part of the signal is third- powered in the third power circuit 14. The third-powered signal and the signal from the phase delay circuit 13 are superimposed and fed to the adder 15, where AC bias signal is superimposed, and the superimposed signal is fed to the recording magnetic head 16. Thus, the recorded phase of each signal recorded as residual magnetization on the magnetic recording media is in agreement. Even with lower tape running speed, the operation compensating the distortion of third harmonics through the use of the third power circuit can not be defected to establish excellent magnetic recording and reproduction.

Abstract: PURPOSE:To transmit plural signals simultaneously by replacing lower bits by data other than sound data in case of transmitting signals obtained by converting an analog signal such as an audio signal into a digital signal consisting of plural bits. CONSTITUTION:When a slot consisting of 16 bits is prepared as signal formats and sound and picture data are inserted into the format to be transmitted, a flag code consisting of 2 bits is inserted into the LSB side and 4 kinds of signals formats are transmitted in accordance with the combinations of the flag codes. When the flag codes are ''00'', ''01'' and ''10'', linear quantized sound data consisting of 14 bits, sound data of 10 bits and picture data of 4 bits, and nonlinear sound data of 10 bits and picture data of 4 bits are sent, respectively. Consequently, switches S2, S3 are changed by a flag encoder 17 and the transmission of the digitized signal of a sound signal from a terminal 1 or a signal obtained by mixing the digital sound signal with the digitized signal of a picture signal from a tuner 9 is controlled.

Abstract: PURPOSE:To reduce the breather due to noises under the condition having no deterioration in the sound quality in a high range and no clear noise in a low range by using a preemphasis circuit having different gains for different bands. CONSTITUTION:One input signal is fed to the preset LPF filter 16 of a preemphasis circuit so that the mid-range band becomes the low range signals which are attenuated more than a low range band. The other input signal is amplified by an ampli fier 17 into high range signals through an HPF 18 so that the resultant high signals are added to the low range signals from the LPF 16 by an adder 19. As a result, the composed output has a higher gain at a middle range than at a low range and has also a higher gain at a high range than the low range so that the frequency characteristics of each band is so adjusted as to have no deterioration in the sound guality in the high range. Thus,it is possible to generate such signals as have their breathers of the noises reduced under the condition having no clear noise in the low range.
