HDMI-CEC<\/strong> (High-Definition Multimedia Interface \u2013 Consumer Electronics Control) je protokol navrhnut\u00fd na optimaliz\u00e1ciu v\u00fdkonu viacer\u00fdch zariaden\u00ed pripojen\u00fdch cez HDMI. Prim\u00e1rne sa pou\u017e\u00edva na ovl\u00e1danie r\u00f4znych komponentov pripojen\u00fdch k telev\u00edzoru, ako s\u00fa soundbary a prehr\u00e1va\u010de videa.

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

Consumer Electronics Control (CEC)<\/strong> vznikol v 80. rokoch minul\u00e9ho storo\u010dia, ke\u010f sa videorekord\u00e9ry (VCR) 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\u017ei\u0165 audio syst\u00e9m na zlep\u0161enie zvuku. Vyn\u00e1lez SCART konektora zrevolucionizoval toto nastavenie t\u00fdm, \u017ee zjednotil viacero portov \u2013 ktor\u00e9 boli predt\u00fdm potrebn\u00e9 pre telev\u00edzory, videorekord\u00e9ry a audio zariadenia \u2013 do jedn\u00e9ho multifunk\u010dn\u00e9ho rozhrania. T\u00e1to inov\u00e1cia tie\u017e zaviedla protokol ovl\u00e1dania, ktor\u00fd umo\u017enil zariadeniam bezprobl\u00e9movo si navz\u00e1jom posiela\u0165 pr\u00edkazy.<\/p>\n\n\n\n

S prechodom na HDMI porty bol CEC<\/strong> integrovan\u00fd do tohto nov\u00e9ho digit\u00e1lneho \u0161tandardu, pri\u010dom sa ovl\u00e1danie zariaden\u00ed prenieslo z anal\u00f3gov\u00fdch na digit\u00e1lne pripojenia. Preto\u017ee v\u0161ak podpora CEC<\/strong> nebola povinn\u00e1, jej implement\u00e1cia sa u r\u00f4znych v\u00fdrobcov elektronick\u00fdch zariaden\u00ed l\u00ed\u0161ila.<\/p>\n\n\n\n

Pou\u017e\u00edvanie a pr\u00edkazy HDMI-CEC<\/strong><\/h2>\n\n\n\n

HDMI-CEC<\/strong> (Consumer Electronics Control) v\u00e1m umo\u017e\u0148uje ovl\u00e1da\u0165 viacer\u00e9 zariadenia pomocou jedn\u00e9ho dia\u013ekov\u00e9ho ovl\u00e1da\u010da. V podstate jedno zariadenie m\u00f4\u017ee vysiela\u0165 pr\u00edkazy do in\u00fdch pripojen\u00fdch zariaden\u00ed. Predstavte si napr\u00edklad, \u017ee m\u00e1te telev\u00edzor, streamovacie zariadenie ako Roku alebo Chromecast pripojen\u00e9 k HDMI portu telev\u00edzora a zvukov\u00fd prij\u00edma\u010d alebo soundbar pripojen\u00fd k in\u00e9mu portu ozna\u010den\u00e9mu HDMI ARC<\/strong> (eARC). Aktiv\u00e1ciou HDMI-CEC<\/strong> na v\u0161etk\u00fdch t\u00fdchto zariadeniach m\u00f4\u017eu fungova\u0165 ako jeden syst\u00e9m. Zapnutie jedn\u00e9ho zariadenia automaticky zapne v\u0161etky pripojen\u00e9 zariadenia. Napr\u00edklad m\u00f4\u017eete po\u017eiada\u0165 Alexu, aby zapla telev\u00edzor, a soundbar a Chromecast sa tie\u017e zapn\u00fa. Potom 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
