DTV Encoder Modulator

Lub Digital TV Encoder Modulator yog ib qho cuab yeej siv hauv cov tshuab digital headend los encode digital TV signals. Nws siv cov teeb liab digital los ntawm digital headend system thiab hloov lawv mus rau hauv xov tooj cua zaus teeb liab rau kev sib kis. Nyob rau hauv ib tug digital headend system, Digital TV Encoder Modulator feem ntau yog thawj cov cuab yeej siv los ua cov cim digital. Lub encoder modulator ces modulates lub teeb liab thiab xa mus rau lub kav hlau txais xov los yog satellite tais. Lub teeb liab modulated tau txais los ntawm TV receivers, uas txiav txim siab lub teeb liab thiab tso saib cov ntsiab lus digital. Lub Digital TV Encoder Modulator yog ib qho tseem ceeb ntawm txhua qhov digital headend system thiab yog lub luag haujlwm los xyuas kom meej tias cov ntsiab lus digital tau xa tuaj raws li kev ntseeg tau thiab ua tau zoo.

Vim li cas digital TV Encoder Modulator tseem ceeb?
Lub TV Digital Encoder Modulator yog qhov tseem ceeb vim tias nws tso cai rau TV teeb liab xa mus rau hauv cov hom ntawv, tsis yog analog. Qhov no tuaj yeem muab cov duab thiab suab zoo dua qub thiab tuaj yeem tso cai rau cov yam ntxwv ntxiv xws li cov kev pabcuam sib tham sib, ntau lub suab thiab video ntws, thiab cov ntaub ntawv kev pabcuam.
Muaj pes tsawg hom digital TV Encoder Modulator muaj thiab qhov sib txawv ntawm txhua tus ntawm lawv yog dab tsi?
Muaj peb yam tseem ceeb ntawm TV Encoder Modulators: Analog, Digital, thiab Hybrid.

Analog Encoder Modulators hloov cov teeb liab analog, xws li xov tooj cua thiab TV tshaj tawm, rau hauv daim ntawv digital rau kev sib kis. Digital Encoder Modulators hloov cov teeb liab, xws li los ntawm satellite lossis cable TV muab kev pabcuam, rau hauv daim ntawv tsim nyog rau kev tshaj tawm hauv TV. Hybrid Encoder Modulators muab cov yam ntxwv los ntawm ob qho tib si Analog thiab Digital Encoder Modulators, tso cai rau cov tswv yim ntawm ob qho tib si analog thiab digital signals.
