Способ и устройство формирования программируемых испытательных сигналов и страниц телетекста относится к технике телевидения. Устройство может применяться при измерении и контроле параметров аналоговых и цифровых сигналов дополнительной информации типа телетекста, передаваемых в составе телевизионного сигнала, а также каналов их передачи, и может быть использовано для контроля работы декодеров телетекста ТВ-приемников. Устройство формирует испытательные сигналы, позволяющие оценить верность передачи цифровой дополнительной информации, совместимость одновременной передачи цифровой дополнительной информации типа телетекста с сигналом звукового сопровождения, осуществить измерение ближних и дальних повторов в канале изображения. Формируемые в устройстве испытательные страницы предназначены для визуальной оценки работы декодера телетекста и сквозного канала передачи цифрового сигнала дополнительной информации. Устройство позволяет осуществить контроль и измерение параметров системы телевизионного коллективного приема и ТВ-приемников с встроенными декодерами телетекста. Устройство работает как при наличии полного цветового телевизионного сигнала, так и при наличии радиосигнала вещательного телевидения.A method and apparatus for generating programmable test signals and teletext pages relates to a television technique. The device can be used to measure and control the parameters of analog and digital signals of additional information such as teletext transmitted as part of a television signal, as well as their transmission channels, and can be used to control the operation of TV receivers teletext decoders. The device generates test signals to evaluate the fidelity of the transmission of digital additional information, the compatibility of the simultaneous transmission of digital additional information such as teletext with the audio signal, and to measure near and far repeats in the image channel. Test pages generated in the device are intended for visual evaluation of the operation of the teletext decoder and the pass-through channel for transmitting the digital signal of additional information. The device allows you to monitor and measure the parameters of the system of television collective reception and TV receivers with built-in teletext decoders. The device operates both in the presence of a full color television signal and in the presence of a broadcast television signal.
