Kev piav qhia
Lub HDMI digital modulator yog ib qho khoom siv uas hloov HDMI cov teeb liab mus rau hauv xov tooj cua zaus signals (RF), feem ntau yog siv los faib cov qib siab - zoo digital video thiab audio signals rau ntau yam khoom siv. Nws yog feem ntau siv hauv tsev so thiab tsev kho mob, tsev kawm ntawv, chaw ua kis las thiab cov chaw pej xeem, chaw ua haujlwm, chaw ua yeeb yam hauv tsev, thiab lwm yam.
Cov xwm txheej ntawm daim ntawv thov no siv lub peev xwm ntawm digital HDMI modulators kom ua tiav kev faib tawm thiab kev tswj hwm ntawm siab -cov lus txhais, txhim kho cov neeg siv kev paub thiab kev ua haujlwm yooj yim.
Peb cov HDMI digital modulator tuaj yeem tsim DVB-T / C hom (digital terrestrial TV) signals los ntawm HDMI input. H264 encoding, DVB-T/C modulation integrated device, converts HDMI signals rau DVB-T/C RF output. Nws yog txawm peem rau nrog ib tug channel HDMI input, HDMI tawm (HDMI pass-tab sis), thiab ib tug DVB-T / C RF tso zis.
Qhov digital HDMI modulator no siv cov kev hloov pauv DVB-T / C tsis txwv los kho tus nqi compression rau bandwidth muaj.
Nws hloov cov teeb liab HDMI rau hauv DVB-T / C RF tso zis thiab IR rov qab txoj hauv kev kom tso cai hloov pauv ntawm lwm chav. Tau yooj yim tswj cov chaw taws teeb tswj cov teeb liab los ntawm coaxial cables. Ntev kis tau tus mob, yooj yim installation, ntsaws thiab ua si.
