Ukuphindaphindwa kweetshaneli zedijithali ze-DVB-T2: idatha yangoku ngo-2026

Ngokutshintshwa kosasazo lwe-analog kunye nosasazo lwedijithali (i-DTV) kumabonwakude waseRussia, kuye kwafuneka ukuba kuthengwe kwaye kuqwalaselwe izixhobo ezongezelelweyo. Izixhobo ezidlulisa umqondiso we-terrestrial kufuneka zilungelelaniswe ngamaxesha afunekayo.

DVB-T2 ijelo kamabonakude yedijithali frequencies eRashiya naseMoscow

Ukusebenza komabonakude womhlaba wedijithali eRashiya kwenzeka kwiifrikhwensi ezisebenza kwibhendi ukusuka kwi-470 – 862 MHz, kumajelo angama-21 ukuya ku-69. Ummandla ojongene ne-DTV wengingqi ubonisa ukhetho lomlambo apho i- digital set-top box okanye i-TV iya kuba khona . iqwalaselwe.

Kukhetho lokukhangela okwenziwa ngesandla, kufuneka ufake ubuninzi betshaneli oyifunayo.

I-TV kunye ne-set-top yesethingi yebhokisi yetafile kunye ne-TV yedijithali.

Ulwazi oluyimfuneko malunga nedatha yefrikhwensi kunye nommandla wokugubungela imimandla nganye inikezelwe kwimephuInkonzo ibonelela ngokufunyanwa ngokuzenzekelayo kwendawo apho iphepha lifakwe khona.

Ii-Multiplexes zamajelo edijithali

Ukuqeshwa kwamajelo edijithali kwiphakheji kuthiwa yi-multiplex (RTRS). I-Tuning ibandakanya ukumisela i-frequencies kwi-decimeter wave coverage.

I-RTRS №1-multiplex

Le phakheji ibonelela uluntu (simahla) ngamajelo omabonakude kunye nawerediyo. Ulwazi olusasazwa ngamajelo lubalulekile ekuhlaleni kwaye luvunywe nguMongameli weRussian Federation.
Imilinganiselo ngokubanzi ye-RTRS Nomb. 1:

• amaza e-decimeter ukusuka kwi-470 ukuya kwi-862 MHz;
• umgangatho wosasazo weDVB-T2;
• umthamo wosasazo lwe-SDTV;
• akukho uguqulelo oluntsonkothileyo.

Uluhlu lwesitishi esininzi #1:

• Eyokuqala;
• iRashiya 1;
• Umdlalo;
• NTV;
• inkcubeko;
• Umjelo wesi-5;
• iRashiya 24;

• Irediyo yaseRashiya;
• Indlu yesibane;
• Vesti FM.

I-RTRS №2-multiplex

Ipakethe yosasazo lukamabonakude wedijithali kunye nonomathotholo lunikezelwa simahla ngumsebenzisi, kodwa ukusetyenziswa okuhlawulelwayo kunye nokurhuma kunokwenzeka. RTRS #2 useto lweparameter:

• ukhetho lwee-frequencies 470-862 MHz;
• ifomathi ye-SDTV;
• akukho luguqulelo oluntsonkothileyo;
• DVB-T2 umgangatho wophawu.

Uluhlu lwesitishi esininzi #2:

• RenTV;
• Igciniwe;
• STS;
• Ikhaya;
• iTV3;
• ULwesihlanu;
• Inkwenkwezi;
• Ihlabathi;
• TNT;
• Muz TV.

I-RTRS №3-multiplex

Ipakethi yokuvavanya iziteshi zeTV zisasazwa kwintsimi yaseMoscow kunye nommandla waseMoscow. Uluhlu lovavanyo lwamajelo angama-40 ayiloluhlu lokugqibela oluvunyiweyo. Usasazo lwepakethi lulungelelaniswe kwi-578 MHz.
Uluhlu lweetshaneli eziphindaphindwayo №3:

• Imidlalo 1;
• Imidlalo 2;
• inoveli yesiRashiya;
• umthengisi waseRashiya;
• umcuphi waseRashiya;
• Iklabhu yokulwa;
• Iplanethi yam;
• Inzululwazi 2.0;
• Iplanethi ephilayo;
• I-Sundress;
• Ilizwe;
• Iikhathuni;
• Ibali;
• Ipaki yokonwabisa;
• NST;

I-multiplex yesithathu kulindeleke ukuba isungulwe kungekudala kwilizwe lonke.

Ingcamango ye-DVB-T2 kunye neenzuzo zayo

I-DVB-T2 sisishunqulelo sosasazo lwevidiyo yedijithali, apho i-“T” imele ukuhanjiswa kwedatha emoyeni. Ukusetyenziswa kwemodyuli ye-COFDM yokusasaza amajelo kumgangatho weHD. Kuyenzeka ukuba ucinezele umlambo wevidiyo kwi-MPEG-2 ifomathi kunye nokudlulisa idatha ukuya kwi-31 Mb / s. Xa kuthelekiswa ne-DVB-T, umgangatho omtsha wazisa:

• ukwanda kwamajelo e-multiplex;
• ukuphucula ukusebenza kosasazo lukamabonakude lwasekuhlaleni;
• ukusebenza kwenkcazo ephezulu;
• ukukhululwa kwee-ethereal frequencies.

Akukho nto inzima ekuseteni iifrikhwensi zamatshaneli edijithali kwaye kulula ukwenza ngokwakho. Kwanele ukusebenzisa idatha enikwe kwiitafile.
