Ukuze inganekwane lingagcwaliseki, ekhiqizwa ezihlukahlukene abamukelayo yedijithali ithelevishini eliwumhlaba, noma njengoba bebizwa kanjalo, amabhokisi usethe-top noma abamukelayo. Basuke axhunyiwe njengoba nakuyicabanga, ngaphezu lukamakhalekhukhwini. Bangakwazi ezakhelwe ithelevishini noma idivayisi ehlukile.

nokuthuthukisa ithekhnoloji

Yaqala ukusakaza e DVB-T format. Kodwa ukuvela Umabonakude hhayi emi namanje. Kwakukhona ezintsha okuthuthukile. DVB-T2 ejwayelekile zanamuhla uye waba esakazwa e-Europe, bese yasungulwa futhi ensimini ka-Russia. Nakuba kokubili izinhlobo digital isignali ukudluliswa usebenze parallel, kodwa yesibili kancane kancane esikhundleni ngokuphelele wokuqala. Image MPEG4 idluliselwa ifomu onomfutho olubanzi nesinqumo imigqa ayisithupha namashumi amabili nanhlanu futhi igcina umsindo Dolby AC-3. Esiginali ukudluliswa ayitsintseki sezulu izimo. Xhuma umamukeli TV ilula ngokwanele. Lo msebenzi Ungasingatha, futhi engumshumayeli. Kodwa okokuqala, sibheka amadivayisi ezinikeza ezitolo nezingosi ze-Internet..
