V posledn\u00fdch rokoch sa na \u00fazem\u00ed Ruska, Ukrajiny a Bieloruska diskutovalo o zaveden\u00ed digit\u00e1lneho rozhlasov\u00e9ho \u0161tandardu DAB+.

N\u00e1pad digit\u00e1lneho r\u00e1dia sa za\u010dal formova\u0165 na konci 80-tych rokov, ke\u010f sa uk\u00e1zalo, \u017ee \"miesta\" v be\u017enom FM p\u00e1sme u\u017e nie je dostatok pre v\u0161etk\u00fdch z\u00e1ujemcov \u2014 vo ve\u013ek\u00fdch mest\u00e1ch bol vo\u013en\u00fd spektrom v p\u00e1sme 88-108MHz vy\u010derpan\u00fd. V tomto oh\u013eade sa DAB pova\u017eoval za slu\u0161n\u00fa alternat\u00edvu \u2014 je to digit\u00e1lny \u0161tandard, v ktorom sa v\u010faka efekt\u00edvnej\u0161iemu k\u00f3dovaniu m\u00f4\u017ee umiestni\u0165 viac stan\u00edc. V prvej verzii DAB sa pou\u017e\u00edval kodek MP2, vo verzii DAB+ modernej\u0161\u00ed HE-AAC. Samotn\u00fd \u0161tandard je pod\u013ea s\u00fa\u010dasn\u00fdch mer\u00edtok dos\u0165 star\u00fd \u2014 prv\u00e1 stanica DAB za\u010dala vysiela\u0165 v roku 1995, a stanica DAB+ v 2007. A pritom, \"vek\" \u0161tandardu je v tomto pr\u00edpade sk\u00f4r plus ako m\u00ednus \u2014 v s\u00fa\u010dasnosti nie je probl\u00e9m k\u00fapi\u0165 si r\u00e1dioprij\u00edma\u010d pod\u013ea svojich predst\u00e1v a pe\u0148a\u017eenky.<\/p>\n

Rozdielov medzi DAB a be\u017en\u00fdm FM je celkom dos\u0165. A nejde len o to, \u017ee jeden je \"digit\u00e1ln\u00ed\" a druh\u00fd \"anal\u00f3gov\u00fd\". Odli\u0161uje sa aj samotn\u00fd princ\u00edp pren\u00e1\u0161ania obsahu. V FM ka\u017ed\u00e1 stanica vysiela samostatne, zatia\u013e \u010do v DAB+ s\u00fa v\u0161etky stanice spojen\u00e9 v \"multiplexe\", v ktorom m\u00f4\u017ee by\u0165 a\u017e 16 stan\u00edc.

\n\"Digit\u00e1lne<\/p>\n

Z poh\u013eadu podnikania vyvol\u00e1va tento rozdiel s\u00e9riu diskusi\u00ed medzi vysielate\u013emi o tom, ako vysiela\u0165 v multiplexe. Predt\u00fdm si vysielatelia sami obstarali licenciu na frekvenciu, k\u00fapili ant\u00e9nu a vysiela\u010d, teraz bude licencia vyd\u00e1van\u00e1 oper\u00e1torovi multiplexu, ktor\u00fd u\u017e prenajme kan\u00e1ly r\u00e1diostaniciam. Je to lep\u0161ie alebo hor\u0161ie, \u0165a\u017eko poveda\u0165, niekomu vyhovuje ma\u0165 v\u0161etko svoje, in\u00e9mu je pohodlnej\u0161ie pren\u00e1jom.<\/p>\n

Mimochodom, z tohto poh\u013eadu m\u00e1 DAB obrovsk\u00fd a v\u00fdrazn\u00fd m\u00ednus pre posluch\u00e1\u010da \u2014 cena pren\u00e1jmu multiplexu z\u00e1vis\u00ed od bitrate.<\/u>. A ak si vyberiete medzi 192 a 64kbps... v\u0161etk\u00fdm je asi jasn\u00e9, \u010do bude vybran\u00e9. Zatia\u013e \u010do vysiela\u0165 v FM s n\u00edzkou kvalitou je pomerne n\u00e1ro\u010dn\u00e9, v DAB to je dokonca hospod\u00e1rsky podporovan\u00e9 (je jasn\u00e9, \u017ee to nie je vina v\u00fdvoj\u00e1rov \u0161tandardu, ale aj tak). Rusk\u00e9 ceny zatia\u013e nie s\u00fa zn\u00e1me, ale anglick\u00e9 si m\u00f4\u017eeme pozrie\u0165 ako pr\u00edklad. tu<\/a><\/noindex>.<\/p>\n

Z technick\u00e9ho h\u013eadiska je multiplex DAB+ \u0161irokop\u00e1smov\u00fd sign\u00e1l, s \u0161\u00edrkou spektra okolo 1,5 MHz, ktor\u00fd je dobre vidite\u013en\u00fd s RTL-SDR prij\u00edma\u010dom.

Zhrnutie<\/h2>\n

Ak hovor\u00edme o perspekt\u00edvach digit\u00e1lneho rozhlasov\u00e9ho vysielania, bohu\u017eia\u013e s\u00fa dos\u0165 smutn\u00e9. Hlavnou v\u00fdhodou DAB je efekt\u00edvnej\u0161ie vyu\u017eitie spektra, \u010do umo\u017e\u0148uje umiestni\u0165 do vysielania viac stan\u00edc. Z tohto h\u013eadiska m\u00e1 DAB+ zmysel len pre tie mest\u00e1, kde u\u017e nie je vo\u013en\u00e9 miesto na FM. Pre Rusko to bude pravdepodobne len Moskva a Petrohrad, vo v\u0161etk\u00fdch ostatn\u00fdch mest\u00e1ch tak\u00e9to probl\u00e9my nie s\u00fa.<\/p>\n

Pokia\u013e ide o kvalitu zvuku, technicky dok\u00e1\u017ee DAB+ zabezpe\u010di\u0165 bitrate a\u017e do 192 Kbps, \u010do by malo prinies\u0165 takmer HiFi zvuk. V praxi v\u0161ak, ako vid\u00edme vy\u0161\u0161ie, vysielatelia \u0161etria a neprekonaj\u00fa ani hranicu 100 Kbps. Z troch multiplexov sa na\u0161la iba jedna (!) stanica, ktor\u00e1 vysiela v 96 Kbps (a \u00faprimne, vysielanie hudby s 48 Kbps nem\u00f4\u017eem nazva\u0165 inak ako r\u00fahan\u00edm \u2013 tak\u00fdch vysielate\u013eov by mali zbavi\u0165 licenci\u00ed;). Tak\u017ee bohu\u017eia\u013e, m\u00f4\u017eem s istotou poveda\u0165, \u017ee prechodom z FM na DAB sa kvalita zvuku zhor\u0161\u00ed. hor\u0161ia ako bola.<\/u>. Samozrejme, v in\u00fdch krajin\u00e1ch m\u00f4\u017ee by\u0165 situ\u00e1cia lep\u0161ia, ale napr\u00edklad anglick\u00e1 recenzia na youtube s v\u00fdre\u010dn\u00fdm n\u00e1zvom Why DAB sounds so BAD<\/a><\/noindex>. Technicky je DAB dobr\u00fd a nem\u00e1 s n\u00edm s\u0165a\u017enosti, ale ekonomicky, 'peniaze zv\u00ed\u0165azili nad zlom'.<\/p>\n

\u010co sa t\u00fdka Ruska, m\u00e1 zmysel v\u00f4bec zaobera\u0165 sa za\u010dat\u00edm vysielania v DAB? Z h\u013eadiska medzin\u00e1rodn\u00e9ho prest\u00ed\u017ee, asi \u00e1no, aby sme nevyzerali v o\u010diach susedov ako zaostal\u00e1 krajina tretieho sveta, a ako bonus, aby zak\u00fapen\u00e9 automobily a r\u00e1di\u00e1 v Eur\u00f3pe mohli plnohodnotne prij\u00edma\u0165 v\u0161etky stanice. Ale z h\u013eadiska posluch\u00e1\u010dov a kvality zvuku pravdepodobne nedostan\u00fa \u017eiadne v\u00fdhody ani v kvalite zvuku, ani v kvalite obsahu.<\/p>\n

Ak sa v\u0161ak zamysl\u00edme nad vzdialen\u00fdmi perspekt\u00edvami, v bud\u00facnosti pravdepodobne bude r\u00e1dio zariaden\u00edm s integrovanou e-sim kartou a predplatn\u00fdm na Yandex-Music, Spotify alebo Apple Music pri zak\u00fapen\u00ed. Bud\u00facnos\u0165 patr\u00ed bezpochyby streamovac\u00edm slu\u017eb\u00e1m a personalizovan\u00e9mu obsahu. Ako r\u00fdchlo sa to stane, uvid\u00edme, \u010das uk\u00e1\u017ee.<\/p>\n
