Dnes pova\u017eujeme za samoz\u0159ejmost, \u017ee m\u016f\u017eeme sledovat \u017eiv\u00e9 televizn\u00ed p\u0159enosy z ud\u00e1lost\u00ed, jako je mistrovstv\u00ed sv\u011bta ve fotbale nebo olympijsk\u00e9 hry. Tyto z\u00e1b\u011bry \u010dasto putuj\u00ed na va\u0161i obrazovku z druh\u00e9 strany sv\u011bta.<\/p>\n<\/div>\n

To umo\u017e\u0148uje prstenec komunika\u010dn\u00edch satelit\u016f na geostacion\u00e1rn\u00ed ob\u011b\u017en\u00e9 dr\u00e1ze. Tyto satelity, kter\u00e9 ob\u00edhaj\u00ed ve v\u00fd\u0161ce p\u0159ibli\u017en\u011b 36 000 km nad rovn\u00edkem, se zdaj\u00ed vzn\u00e1\u0161et nad stejnou \u010d\u00e1st\u00ed zemsk\u00e9ho povrchu.

Modern\u00ed \u00e9ra satelitn\u00ed televize za\u010dala v \u010dervenci 1962, kdy satelit Telstar 1 p\u0159enesl prvn\u00ed \u017eiv\u00e9 televizn\u00ed po\u0159ady ze Spojen\u00fdch st\u00e1t\u016f do Velk\u00e9 Brit\u00e1nie. V roce 1965 se pak satelit Early Bird stal prvn\u00edm satelitem, kter\u00fd se pou\u017e\u00edval k pravideln\u00e9mu televizn\u00edmu vys\u00edl\u00e1n\u00ed mezi Severn\u00ed Amerikou a Evropou.<\/p>\n

V minulosti musely b\u00fdt televizn\u00ed sign\u00e1ly nejprve vys\u00edl\u00e1ny do velk\u00fdch parabolick\u00fdch ant\u00e9n ve speci\u00e1ln\u00edch pozemn\u00edch stanic\u00edch, ne\u017e byly d\u00e1le \u0161\u00ed\u0159eny do m\u00edstn\u00edch ant\u00e9n. Dnes jsou satelitn\u00ed sign\u00e1ly tak siln\u00e9, \u017ee je lze zachytit pomoc\u00ed mal\u00fdch parabolick\u00fdch ant\u00e9n na st\u0159ech\u00e1ch kancel\u00e1\u0159\u00ed a dom\u016f. Tato digit\u00e1ln\u00ed televize s p\u0159\u00edm\u00fdm p\u0159enosem do dom\u00e1cnost\u00ed se v mnoha zem\u00edch stala velmi popul\u00e1rn\u00ed.<\/p>\n

Mezi vzd\u00e1len\u00fdmi pobo\u010dkami nebo mezi l\u00e9ka\u0159i v m\u011bstsk\u00fdch nemocnic\u00edch a pacienty v odlehl\u00fdch venkovsk\u00fdch obc\u00edch lze rovn\u011b\u017e z\u0159\u00eddit \u017eiv\u00e9 satelitn\u00ed spojen\u00ed.
