Imvamisa yeziteshi zikamabonakude zedijithali ze-DVB-T2: idatha yamanje ka-2025

Ngokushintshwa kokusakaza kwe-analog ngokusakaza kwedijithali (i-DTV) kuthelevishini yaseRussia, kwadingeka ukuthi kuthengwe futhi kumiswe imishini eyengeziwe. Izinsimbi ezidlulisa isignali yasemhlabeni kufanele zishuniswe kufrikhwensi edingekayo.

DVB-T2 digital isiteshi sethelevishini amaza eRussia naseMoscow

Ukusebenza kukamabonakude wasemhlabeni wedijithali e-Russia kwenzeka kumafrikhwensi asebenza ebhendini asuka ku-470 – 862 MHz, eziteshini 21 kuya ku-69. Indawo ekhavayo ye-DTV yesifunda isho ukukhethwa kokusakaza lapho ibhokisi le-
digital set-top noma i-TV izoba khona. kulungisiwe.

Kunketho yokusesha okwenziwa ngesandla, kufanele ufake imvamisa yesiteshi osifunayo.

Ithebula lezilungiselelo ze-TV ne-set-top box elinamaza e-TV edijithali.

Ulwazi oludingekayo mayelana nedatha yemvamisa kanye nendawo ehlanganisa izifunda ngazinye inikezwa kumephu
Isevisi ihlinzeka ngokutholwa okuzenzakalelayo kwesifunda lapho ikhasi lifakwe khona.

I-Multiplexes yamashaneli edijithali

Ukusebenza kwamashaneli edijithali kuphakheji kubizwa ngokuthi i-multiplex (RTRS). Ukushuna kuhilela ukunquma amafrikhwensi ekukhavekeni kwegagasi lamadesimitha.

I-RTRS №1-multiplex

Le phakheji inikeza iziteshi zomphakathi (mahhala) zikamabonakude nezomsakazo. Ulwazi olusakazwa iziteshi lubalulekile emphakathini futhi lugunyazwe nguMongameli Wenhlangano YaseRussia.
Imingcele evamile ye-RTRS No. 1:

• amagagasi e-decimeter kusuka ku-470 kuya ku-862 MHz;
• ukusakaza standard DVB-T2;
• umthamo wokusakazwa kwe-SDTV;
• akukho ukubethela.

Uhlu lweziteshi eziningi #1:

• Okokuqala;

• Vesti FM.

I-RTRS №2-multiplex

Iphakethe lokusakazwa komabonakude wedijithali nomsakazo linikezwa mahhala ngu-opharetha, kodwa ukusetshenziswa okukhokhelwayo nakho kuyenzeka. Izilungiselelo zepharamitha ye-RTRS #2:

• ukukhethwa kwamafrikhwensi 470-862 MHz;
• Ifomethi ye-SDTV;
• akukho ukubethela;
• DVB-T2 isignali standard.

Uhlu lweziteshi eziningi #2:

• I-RenTV;
• Ilondoloziwe;
• I-STS;
• Ikhaya;
• I-TV3;
• NgoLwesihlanu;
• Inkanyezi;
• Umhlaba;
• I-TNT;
• Muz TV.

I-RTRS №3-multiplex

Iphakheji yokuhlola yeziteshi ze-TV isakazwa endaweni yaseMoscow kanye nesifunda saseMoscow. Uhlu lwamashaneli angama-40 alulona uhlu lokugcina olugunyaziwe. Ukusakazwa kwephakethe kushunwe ku-578 MHz.
Uhlu lwamashaneli amaningi №3:

• Ezemidlalo 1;
• Ezemidlalo 2;
• inoveli yesiRashiya;
• umthengisi waseRussia;
• umphenyi waseRussia;
• Fight club;
• Iplanethi yami;
• Isayensi 2.0;
• Iplanethi ephilayo;
• I-Sundress;
• Izwe;
• Ikhathuni;
• Indaba;
• Iphaki lokuzilibazisa;
• I-NST;

I-multiplex yesithathu kulindeleke ukuthi yethulwe maduze ezweni lonke.

Umqondo DVB-T2 kanye nezinzuzo zayo

I-DVB-T2 isifinyezo sokusakazwa kwevidiyo yedijithali, lapho u-“T” umele ukudluliswa kwedatha emoyeni. Ukusetshenziswa okujwayelekile kwe-COFDM isakaza iziteshi ngekhwalithi ye-HD. Kuyenzeka ucindezele ukusakaza kwevidiyo ngefomethi ye-MPEG-2 futhi udlulise idatha ifike ku-31 Mb/s. Uma kuqhathaniswa ne-DVB-T, izinga elisha lethula:

• ukwanda kwamashaneli amaningi;
• ukwenza ngcono ukusebenza kokusakaza kumabonakude wendawo;
• ukusebenza kwencazelo ephezulu;
• ukukhululwa kwe-ethereal frequencies.

Akukho lutho oluyinkimbinkimbi ekusetheni amaza eziteshi zedijithali futhi kulula ukuzenza uwedwa. Kwanele ukusebenzisa idatha enikezwe kumathebula.
