Napriek svojej pohodlnosti je HDMI-CEC pomerne jednoduch\u00e1 a zastaran\u00e1 technol\u00f3gia, ktor\u00e1 podporuje iba obmedzen\u00fd po\u010det pr\u00edkazov.

Hist\u00f3ria HDMI CEC<\/strong><\/h2>\n\n\n\n

\u0160tandard Consumer Electronics Control (CEC)<\/strong> vznikol v 80. rokoch, ke\u010f sa videorekord\u00e9ry a audio syst\u00e9my st\u00e1vali \u010doraz be\u017enej\u0161\u00edmi. V tom \u010dase bolo be\u017en\u00e9 pripoji\u0165 videorekord\u00e9r k telev\u00edzoru a pou\u017e\u00edva\u0165 reproduktorov\u00fd syst\u00e9m na zlep\u0161enie kvality zvuku. Vyn\u00e1lez konektora SCART sp\u00f4sobil v tejto oblasti revol\u00faciu, preto\u017ee spojil viacero portov, ktor\u00e9 boli predt\u00fdm potrebn\u00e9 na prepojenie telev\u00edzorov, videorekord\u00e9rov a audio zariaden\u00ed, do jedn\u00e9ho multifunk\u010dn\u00e9ho rozhrania. To viedlo aj k v\u00fdvoju riadiaceho protokolu, ktor\u00fd umo\u017enil ovl\u00e1danie viacer\u00fdch zariaden\u00ed jedn\u00fdm dia\u013ekov\u00fdm ovl\u00e1da\u010dom.<\/p>\n\n\n\n

S prechodom na HDMI porty bol protokol CEC integrovan\u00fd do tohto nov\u00e9ho digit\u00e1lneho \u0161tandardu, \u010do umo\u017enilo prechod z anal\u00f3gov\u00e9ho na digit\u00e1lne ovl\u00e1danie zariaden\u00ed. Ke\u010f\u017ee podpora CEC nebola povinn\u00e1, jej implement\u00e1cia sa medzi v\u00fdrobcami l\u00ed\u0161ila. Jednoducho povedan\u00e9, nie v\u0161etky pr\u00edkazy boli podporovan\u00e9; napr\u00edklad mnoh\u00e9 soundbary podporovali iba zapnutie\/vypnutie a ovl\u00e1danie hlasitosti.<\/p>\n\n\n\n

Pr\u00edklad pou\u017eitia HDMI CEC a podporovan\u00e9 pr\u00edkazy<\/strong><\/h2>\n\n\n\n

HDMI CEC (Consumer Electronics Control) umo\u017e\u0148uje ovl\u00e1danie viacer\u00fdch zariaden\u00ed pomocou jedn\u00e9ho dia\u013ekov\u00e9ho ovl\u00e1da\u010da. V praxi m\u00f4\u017ee jedno zariadenie odosiela\u0165 pr\u00edkazy ostatn\u00fdm pripojen\u00fdm zariadeniam.<\/p>\n\n\n\n

Napr\u00edklad m\u00f4\u017eete ma\u0165 telev\u00edzor, streamovacie zariadenie ako Roku alebo Chromecast pripojen\u00e9 k HDMI portu telev\u00edzora a AV prij\u00edma\u010d alebo soundbar pripojen\u00fd k in\u00e9mu portu ozna\u010den\u00e9mu HDMI ARC (eARC). Ke\u010f je HDMI CEC aktivovan\u00fd na v\u0161etk\u00fdch t\u00fdchto zariadeniach, m\u00f4\u017eu fungova\u0165 ako jeden syst\u00e9m. Zapnutie jedn\u00e9ho zariadenia m\u00f4\u017ee automaticky zapn\u00fa\u0165 aj ostatn\u00e9. Napr\u00edklad m\u00f4\u017eete po\u017eiada\u0165 Alexu, aby zapla telev\u00edzor, a soundbar aj Chromecast sa tie\u017e zapn\u00fa. N\u00e1sledne m\u00f4\u017eete ovl\u00e1da\u0165 streamovacie zariadenie a hlasitos\u0165 soundbaru pomocou dia\u013ekov\u00e9ho ovl\u00e1da\u010da telev\u00edzora.<\/p>\n\n\n\n

Na pou\u017e\u00edvanie HDMI CEC je potrebn\u00e9 splni\u0165 ur\u010dit\u00e9 podmienky. HDMI k\u00e1bel mus\u00ed podporova\u0165 CEC a obsahova\u0165 vyhraden\u00fd vodi\u010d na prenos CEC sign\u00e1lov. Niektor\u00e9 lacn\u00e9 HDMI k\u00e1ble m\u00f4\u017eu tento vodi\u010d vynecha\u0165 kv\u00f4li zn\u00ed\u017eeniu v\u00fdrobn\u00fdch n\u00e1kladov. Okrem toho mus\u00ed ka\u017ed\u00e9 zariadenie v syst\u00e9me podporova\u0165 HDMI CEC a funkcia mus\u00ed by\u0165 zapnut\u00e1.<\/p>\n\n\n\n

T\u00e1to funkcia je dnes takmer nepou\u017e\u00edvan\u00e1, preto\u017ee modern\u00e9 telev\u00edzory zriedka podporuj\u00fa priame nahr\u00e1vanie z d\u00f4vodu ochrany autorsk\u00fdch pr\u00e1v.<\/p>\n\n\n\n
