Manaps\u00e1g m\u00e1r term\u00e9szetesnek tartjuk, hogy \u00e9l\u0151ben n\u00e9zhetj\u00fck a telev\u00edzi\u00f3ban olyan esem\u00e9nyeket, mint a vil\u00e1gbajnoks\u00e1g vagy az olimpiai j\u00e1t\u00e9kok. Ezek a k\u00e9pek gyakran a vil\u00e1g m\u00e1sik v\u00e9g\u00e9r\u0151l jutnak el a k\u00e9perny\u0151nkre.<\/p>\n<\/div>\n

Ezt egy geostacion\u00e1rius p\u00e1ly\u00e1n kering\u0151 kommunik\u00e1ci\u00f3s m\u0171holdakb\u00f3l \u00e1ll\u00f3 gy\u0171r\u0171 teszi lehet\u0151v\u00e9. Ezek a m\u0171holdak az Egyenl\u00edt\u0151 felett k\u00f6r\u00fclbel\u00fcl 36 000 km-es magass\u00e1gban keringenek, \u00e9s \u00fagy t\u0171nik, mintha a F\u00f6ld felsz\u00edn\u00e9nek ugyanazon r\u00e9sze felett lebegn\u00e9nek. A f\u00f6ldi parabolaantenn\u00e1kt\u00f3l \u00e9rkez\u0151 telev\u00edzi\u00f3s jeleket veszik, majd azokat feler\u0151s\u00edtik. A m\u0171hold ezut\u00e1n tov\u00e1bb\u00edtja a k\u00e9peket \u00e9s a hangot a n\u00e9z\u0151knek.<\/p>\n

A m\u0171holdas telev\u00edzi\u00f3z\u00e1s modern korszaka 1962 j\u00falius\u00e1ban vette kezdet\u00e9t, amikor a Telstar 1 tov\u00e1bb\u00edtotta az els\u0151 \u00e9l\u0151 telev\u00edzi\u00f3s m\u0171sorokat az Egyes\u00fclt \u00c1llamokb\u00f3l Nagy-Britanni\u00e1ba. Majd 1965-ben az Early Bird lett az els\u0151 m\u0171hold, amelyet rendszeres telev\u00edzi\u00f3s ad\u00e1sokhoz haszn\u00e1ltak \u00c9szak-Amerika \u00e9s Eur\u00f3pa k\u00f6z\u00f6tt.<\/p>\n

R\u00e9gen a telev\u00edzi\u00f3s jeleket el\u0151sz\u00f6r speci\u00e1lis f\u00f6ldi \u00e1llom\u00e1sokon tal\u00e1lhat\u00f3 nagy parabolaantenn\u00e1khoz kellett tov\u00e1bb\u00edtani, miel\u0151tt azokat a helyi antenn\u00e1k fel\u00e9 sug\u00e1rozt\u00e1k volna. Ma a m\u0171holdas jelek olyan er\u0151sek, hogy az irod\u00e1k \u00e9s h\u00e1zak tetej\u00e9n elhelyezett kis parabolaantenn\u00e1kkal is foghat\u00f3k. Ez a k\u00f6zvetlen\u00fcl a h\u00e1ztart\u00e1sokba \u00e9rkez\u0151 digit\u00e1lis telev\u00edzi\u00f3z\u00e1s sz\u00e1mos orsz\u00e1gban nagy n\u00e9pszer\u0171s\u00e9gre tett szert.<\/p>\n
