摘要： PROBLEM TO BE SOLVED: To easily and accurately recognize the broadcasting condition of a desired program by extracting a character code related to a specified character code from program information and displaying a character corresponding to the character code in the prescribed area of a program chart. SOLUTION: A data extraction part 109 extracts program information from data information outputted from a signal separation part 102, decodes it and outputs it to a data storage part 110. The data storage part 110 stores the program information, and a display data preparation part 111 prepares and outputs an image data of the program chart based on outputted program guide information. At this time, the display data preparation part 111 refers to the dictionary of the character code stored in a memory 114 and converts the character code included in the program information to a display data of the character corresponding to it. Then, the image date of the program chart outputted from the display data preparation part 111 are inputted to an image synthesis part 106. Images outputted from the image synthesis part 106 are displayed on a display part.

摘要： PROBLEM TO BE SOLVED: To display an image without deterioration in the image and to prevent the circuit scale from being increased by reading a standard television signal synchronously with a stable oscillation output in the case of reading the standard television signal from a storage section in an N-multiple means so as to conduct double speed conversion and correcting a time base of the signal. SOLUTION: A received standard television signal is written in storage sections 105a, 105b used for double speed conversion in an N multiple means 105 synchronously with an oscillation output from a 2nd oscillation means 107 in common for the double speed conversion. The standard television signal of N multiple speed whose time base fluctuation having been in existence at the reception is outputted by reading the written standard television signal from the storage sections 105a, 105b synchronously with the oscillation output from the 1st oscillation means 124. The standard television signal of N multiple speed is given to a display device 126 synchronously with a horizontal drive pulse from a horizontal drive pulse generating means 109 and displayed thereat.

摘要： PURPOSE:To always provide high-quality pictures by eliminating the picture quality deterioration of video signals after waveform equalization by performing optimum picture quality correction to the video signals after waveform equalization based on the state of input video signals and the information of waveform equalization. CONSTITUTION:An average noise component contained in the video signal is detected by a noise detection circuit 113 and outputted to a picture quality control circuit 114. A tap coefficient arithmetic circuit 116 prepares information for estimating the state of equalized images from tap information at the time of waveform equalization and outputs it to the circuit 114. The circuit 114 prepares picture quality control information and outputs it to a picture quality correction circuit 115 based on noise information outputted from the circuit 113, image state information outputted from the circuit 116 and GCR peak level information prepared from a reference (GCR) signal for ghost removal inserted to the inputted video signal. Thus, high-quality pictures can be always provided without causing deterioration of an S/N or conversely causing unsharpness after waveform equalization.

摘要： PURPOSE:To improve the crosstalk performance by inserting a common base transistor(TR) between two input TRs so that collectors of the two input TRs are not directly connected. CONSTITUTION:TRs 14,15 are connected to collectors of input TRs 3,6 respectively. The collectors of the TRs 14,15 are connected together. Bases of the TRs 3,6 are connected to ground through voltage sources 75,76 respectively to form cascode connection. Thus, in order to disconnect inputs electrically, since cascode connection connecting emitters of common base TRs 14,15 to collectors of the input TRs 3,6 is formed, the signal changeover switch circuit is realized in which crosstalk performance is excellent.

摘要： PURPOSE:To obtain a luminance signal for recording and a video signal for monitoring without distortion and to prevent deterioration in reproduced picture quality by providing a common base amplifier consisting of the 1st TR and the 2nd TR having its emitter connected to the emitter of the 1st TR, and controlling their base voltage in accordance with reproduction and recording. CONSTITUTION:During recording, a TR78 turns on by a constant voltage source 44 and a TR77 turns off. The 1st common base type TR circuit consisting of a TR53, resistance 57, constant voltage source 61, and constant current source 63 operates to generate the luminance signal for recording to a terminal 76 at the base of a TR54. Said luminance signal appears at a terminal 75 by the constant current source of a TR56 and a resistance 60. During reproduction, the constant voltage source 44 turns off, the TR78 turns off, and a constant voltage source 81 impresses a voltage to the base of the TR77, and the TR77 constitutes the 2nd common base type TR circuit and the power source 61 is lower than the source 81, so a TR53 turns off. The reproduced video signal at the terminal 76 is not generated at the base of the TR54 and does not leak into a de-emphasis circuit 21 through the base-collector capacitance of the TR54. The terminal 76 is connected to the common base type circuit, so no waveform distortion due to the mismatching of an LPF4 occurs.
摘要翻译：目的：为了获得用于记录的亮度信号和用于没有失真的监视的视频信号，并且通过提供由第一TR和第二TR组成的公共基本放大器来防止再现的图像质量的劣化，其发射极连接到第一 TR，并根据再现和记录来控制它们的基极电压。构成：在记录期间，TR78通过恒定电压源44导通，TR77关闭。由TR53，电阻57，恒压源61和恒流源63组成的第一公共基极型TR电路用于产生用于记录在TR54的基极处的端子76的亮度信号。所述亮度信号由TR56的恒流源和电阻60出现在端子75处。在再生期间，恒压源44截止，TR78截止，恒压源81将电压施加到 TR77和TR77构成第二公共基极型TR电路，电源61低于源极81，因此TR53截止。端子76处的再现视频信号不是在TR54的基极处产生的，并且不通过TR54的基极集电极电容泄漏到去加重电路21中。端子76连接到公共基极型电路，因此不会发生由于LPF4的不匹配引起的波形失真。
