Abstract: PURPOSE:To comprehend the contents of subtitles in english even if one is not well versed in english. CONSTITUTION:A video signal corresponding to english subtitle broadcasting, for example, received by a TV turner 26 is supplied through an AV switcher 27 to a signal processing IC 30. At the signal processing IC 30, a subtitle signal contained in the video signal is supplied through a TV microcomputer 23 to a translation microcomputer 37. At the translation microcomputer 37, the english subtitles are translated into Japanese subtitles and outputted through the TV microcomputer 23, OSD 25 for TV, OSD processing part 34 and converting part 36 to a CRT 35. Thus, the japanese subtitles are displayed on the CRT 35.

Abstract: PURPOSE: To decide the picture quality in such a way that is equivalent to the visual check of an expert by deciding the quality of images based on a prescribed TV signal produced by a TV signal generator and the detection signal of the video state of a receiver screen. CONSTITUTION: A TV signal generator 4 contains the signal generators for VHF, UHF, CATV, BS and CS channels respectively. Then the generator 4 divides the screen of a TV receiver, for example, into plural areas to produce a color test pattern that includes each of divided areas shown in a prescribed color and outputs a TV signal to display this color test pattern. A color sensor 8 includes the color sensor elements arrayed in accordance with a prescribed color test pattern on one of both sides of a rectangular sheet of a size approximately equal to the screen of a CRT display 15. This sheet is attached on the surface of the display 15 in the check and evaluation modes. Then the color of every area of the color test pattern is detected, and the coincidence is decided between the transmitted color test pattern and a color detection pattern based on the color detection signal.

Abstract: PURPOSE: To reduce the evaluation time and labor needed for the channel selecting operations of a TV receiver and also to reduce the size of an evaluation device by producing a TV signal for every prescribed broadcast channel and selecting a projected equipment. CONSTITUTION: A CPU 1 contains a memory and a timer counter and includes an automatic signal generation program in its memory, and a TV signal generation part 4 produces the TV signals and send them to the input terminal of a TV receiver A that is evaluated. When the execution of the automatic signal generation program is started, the CPU 1 stores the wait time inputted from a keyboard 2 in its memory and then reads the frequency data corresponding to the inputted channel number out of a correspondence table to output them to a general-purpose interface bus 3. When the wait time elapsed, the CPU 1 outputs a remote control code corresponding to the relevant channel to a remote control signal generation part 5 and also outputs the TV signals through the part 4.

Abstract: PURPOSE:To improve the operability of remote control by judging the direction of a commander. CONSTITUTION:Code signals S1-Sc outputted from IC 13a-13c by the operation of a painter key 1 1 are respectively supplied to light-emitting diodes 15a-15c through OR circuits 14a-14c. The code signal outputted from IC 16 by the operation of the pointer key 12 are also supplied to the lightemitting diodes 15a-15c through the OR circuits 14a-14c. The light-emitting diodes are arranged in an up-direction(15a), horizontally(15b) and in a down-direction(15c). Thus, light- emitting is executed form the light-emitting diodes 15a-15c by directivities La-Lc. The light-emitting diodes 15a and 15c and the light-emitting diodes 15b are light-emitted by the code signal so that outputs are weakened at the bondary of the is modulated so that outputs are weakened at the boundary of the respective light-emitting diode directivities.

Abstract: PROBLEM TO BE SOLVED: To provide a control processor for accurately measuring clock frequencies in a short time without interrupting miniaturization or low costs. SOLUTION: This processor is provided with a normal operation mode and a frequency measurement mode. In this frequency measuring mode, a dimmer control terminal IOT1 originally assigned to a dimmer control signal 54 for controlling the brightness of the back light of a liquid crystal display screen is temporarily used as the output of a 1/n frequency-division signal 53 outputted from a programmable frequency-divider 24. Thus, it is not necessary to especially provide any terminal pin for measuring clock frequencies, and a clock signal 52 can be directly recognized by measuring the 1/n frequency-divided signal 53. Therefore, the clock frequencies can be measured in a sharply short time compared with a conventional manner for checking the clock frequencies for several days by using clock display, and the increase of the number of terminal pins can be escaped so that the miniaturization of a device size and low costs can be attained.

Abstract: PURPOSE:To control the ON/OFF of subtitles which are displayed on the TV, the AV center, through a peripheral equipment. CONSTITUTION:Video signals corresponding to subtitle broadcasting received by a TV tuner 26 are outputted through an AV switcher 27, signal processing IC 30 and OSD processing part 34 to a CRT 35 and displayed. When a control signal is supplied from the peripheral equipment (not shown in the figure) through a terminal for D2B and an IC 21 for D2B communication to a D2B microcomputer 22, the D2B microcomputer 22 controls the signal processing IC 30 through a TV microcomputer 23. Thus, at the signal processing IC 30, subtitle signals contained in subtitle broadcasting are superimposed on the video signals of subtitle broadcasting and outputted through the OSD processing part 34 to the CRT 35.

Abstract: PURPOSE:To secure the satisfactory correspondence to a CATV with a channel selector which is capable of remote control, by dividing a reception channel into plural areas and adding a means to select these divided areas. CONSTITUTION:When an auxiliary switch 10 is connected to C, the channel selection is carried out successively between ''1'' and ''36''. While the channel selection is carried out successively between ''1'' and ''24'' when the switch 10 is connected to B. Furthermore the channel selection is performed succesively between ''1'' and ''12'' when the switch 10 is connected to A. Therefore only the radio wave broadcast of both VHF and UHF is selected at all times with a direct channel selection key 21. Then the CATV broadcast of 13-36 channels can be selected in addition to the radio wave broadcast of VHF and UHF with operations of sequential selection keys 15U, 23U, 15D, and 23D respectively. Thus the satisfactory correspondence is secured to the CATV.

Abstract translation: 目的：为了通过将接收通道分成多个区域并添加选择这些分割区域的手段来确保具有能够进行远程控制的频道选择器对CATV的令人满意的对应关系。 构成：当辅助开关10连接到C时，在“1”和“36”之间连续进行通道选择。 当开关10连接到B时，在“1”和“24”之间连续执行频道选择。此外，当“1”和“12”之间的频道选择在“1”和“12” 开关10连接到A.因此，只有通过直接频道选择键21始终选择VHF和UHF两者的无线电波广播。然后除了无线电波广播之外，可以选择13-36个频道的CATV广播 的VHF和UHF，分别具有顺序选择键15U，23U，15D和23D的操作。 因此，令人满意的对应关系确保了CATV。
