As expected , one of the most actual topics is the HDTV technology . Since the most of the television companies plan migrating to HD production in foreseeable future ( with the big sporting events being its main proponent ) , and yet want to retain the current viewers using SD , there were many products dedicated to parallel production in both formats , signal converters , picture croppers due to screen dimensions ( 4:3 vs 16:9 ) , etc.
Prema očekivanju , jedna od najaktualnijih tema je i dalje HDTV . Budući da većina televizijskih kuća planira prelazak na HD ( jedan od najvećih razloga za to su veliki sportski događaji ) , a pritom se ne želi odreći aktualne publike koja gleda SD signal , ponuđena su razna rješenja paralelne produkcije u oba formata , konverteri signala , metode " rezanja " slike zbog razlike u proporcijama ekrana ( 4: 3 i 16: 9 ) , i slično .
