Problemy z odbiorem sygnału cyfrowej telewizji naziemnej DVB-T
Problemy z odbiorem sygnału DVB-T - Cyfrowej Telewizji Naziemnej

Wraz z udostępniem przez nadawcę cyfrowego sygnału telewizji naziemnej pojawiły się nowe problemy, które przy sygnale analogowym nie występowały. Odbierany sygnał DVB-T moze mieć 3 różne zakresy wartości kluczowych parametrów (MER, PreBER, poziom sygnału, ilość utraconych pakietów):
- I - sygnał w zakresie poprawnych parametrów - czysty i płynny obraz bez żadnych zakłóceń,
- II - sygnał w zakresie zbyt niskich parametrów - BRAK SYGNAŁU,
- III - sygnał w zakresie parametrów znajdujących się na granicy pomiędzy sygnałem poprawnym, a brakiem sygnału - obraz klatkuje (zamraża się), pojawiają się kolorowe kwadraciki, zanika fonia itp. Ten trzeci przypadek przedstawia poniższe zdjęcie.

 
   
    Związane jest to przede wszystkim z odległością od nadajnika, rodzajem i typem wykorzystywanych w danej instalacji anten, wzmacniaczy, okablowania itp.

    Nasze doświadczenie pokazuje również inny problem występujący przy próbie odbioru sygnałów DVB-T. Na rynku dostępne są w dalszym ciągu dekodery STB, które nie spełniają wymagań o których mówi stosowna ustawa. Najczęściej występującymi brakami w ich funkcjonalności to: 
- brak obsługi sygnału HD (jest dźwięk, obrazu brak),
- brak obsługi dźwięku Dolby Digital - AC-3, Dolby Digital Plus - E-AC3 (jest obraz, dźwięku brak),
- brak cyfrowego wyjścia obrazu i dźwięku - HDMI.
Pierwsze dwie pozycje mają tu największe znaczenie użytkowe. Co ciekawe, dekodery takie są instalowane przez część instalatorów (ludzi którzy podobno znają się na tym co robią) działających na terenie Częstochowy i okolic!!!
 
    Kolejną "ciekawostką" jest podłączanie przez instalatorów, dekoderów do telewizorów które posiadają wbudowane tunery DVB-T obsługujące MPEG-4. Naszym zdaniem jest to albo ewidentny brak wiedzy w tematyce DVB-T albo próba naciągania klienta na zakup dekodera!!!

In the depths of these very simple Buddhist ideas, I find a very deep and abiding peac.
Example: if citizens believe that a particular restaurant should pay their staff higher wages, then work to pass a law to make it a requirement of ALL restaurants to pay higher wage.
The contractions help make things seem more natural and the words flow better and sound more matur.
