CO OZNACZA SŁOWO TELETEXT
Telegazeta
Teletekst to usługa wyszukiwania informacji telewizyjnych stworzona w Wielkiej Brytanii na początku lat siedemdziesiątych przez Philips Lead Designer dla VDU, John Adams. Teletekst to sposób wysyłania stron z tekstem i prostych kształtów geometrycznych z bloków mozaiki do telewizora wyposażonego w dekoder VBI za pomocą kilku zarezerwowanych pionowych linii wygaszania, które razem tworzą ciemną taśmę dzielącą obrazy poziomo na ekranie telewizora. Oferuje szeroki zakres informacji tekstowych, zazwyczaj zawierających informacje o nowościach, prognozach pogody i telewizji. Informacje o podtytułach są przesyłane również w obrębie sygnału telewizyjnego. Pierwsze transmisje testowe zostały wykonane przez BBC w 1973 roku, znanym jako Ceefax. Po przyjęciu w Wielkiej Brytanii standardy stały się międzynarodowymi standardami europejskiego teletekstu oraz teletekstem systemu światowego. World Wide Web zaczęła przejąć niektóre funkcje teletekstu z końca lat 90., a wielu nadawców przestało transmitować telegazeta-CNN w 2006 i BBC w 2012 roku. Spadek telegazety został przyspieszony przez wprowadzenie cyfrowej telewizji , chociaż aspekt teletekstu jest kontynuowany w napisach zamkniętych.
