FAQ
Q: Qhov no tuner module puas ua haujlwm hauv Samsung dvd-vr470m?
A: Qhov no DVB-T / DVB-T2 module tsuas yog tsim rau kev txhim kho theem nrab los ntawm engineers lossis R&D tuam txhab uas muag.
Q: Puas yog DVB-T receiver decode BISS codes?
A: tsis. Kev ua haujlwm tshaj DVB-T / DVB-T2 H264 265 decoder yog siv rau digital TV receivers thiab COFDM wireless video decoders. Txhua qhov haujlwm tshwj xeeb yuav tsum tiv tauj peb kom paub tseeb lossis txhim kho ntxiv.
Q: Puas yog DVB-T receiver decode txhawb ASI cov zis?
- Lub demodulation nti ntawm peb cov demodulation module siv ib qho kev sib txuas sib txuas hu ua TSI (nws muaj ntau cov ntaub ntawv kab ntau dua li ASI interface)
- Lub demodulation module nws tus kheej tsis muaj MCU thiab tsis tuaj yeem muab rau cov neeg siv khoom ib leeg. Nws yuav tsum tau siv nyob rau hauv peb lub decoding board.
- Piv txwv li, nrog peb decoding board, Peb hloov lub teeb liab los ntawm TSI interface ntawm demodulation module rau hauv lub network chaw nres nkoj teeb liab (piv txwv li, peb ib-txoj kev COFDM pob tshab kis tau tus mob ua qhov no)
