FAQ
Yam tsawg kawg nkaus Order Quantity (MOQ)
Peb cov khoom muaj ntau yam sib txawv, thiab MOQ txawv rau txhua yam khoom. Nws nyob ntawm cov khoom muaj xws li cov khoom muaj, tus nqi ntawm cov khoom, lub sij hawm tsim khoom, kev txiav txim raws li txoj cai, thiab qib khoom muag. Qee cov khoom tuaj yeem txiav txim rau tus kheej, thaum lwm tus yuav xav tau qhov tsawg kawg nkaus yuav ntau dua 1,000 units. Rau qhov tseeb, hloov tshiab MOQ cov ntaub ntawv, thov hu rau peb pab neeg muag khoom.

Headend yog dab tsi?
Lub taub hau ua haujlwm ua lub hauv paus hauv paus hauv kev faib khoom hauv TV. Nws tau txais TV teeb liab los ntawm lwm qhov chaw-xws li satellite, terrestrial, los yog cable feeds-thiab hloov lawv mus rau hauv ib hom ntawv zoo sib xws rau kev faib mus rau TV hauv ib chav. Lub taub hau zoo ib txwm suav nrog cov kav hlau txais xov (satellite thiab / lossis av av) nrog rau cov khoom siv teeb liab uas ua rau cov xwm txheej thiab hloov cov teeb liab tuaj.
Tshaj tawm Headend vs. IPTV Headend
A tshaj tawm headendxa TV signals tshaj ibcoaxial cable networkhauv ib lub tsev.
IbIPTV lub taub haufaib TV raws limulticast IP kwjhla ibLocal cheeb tsam network (LAN).
Yog tias koj muaj cov txheej txheem coaxial uas twb muaj lawm thiab tsis xav hloov mus rau IP-raws li qhov system, qhov kev tshaj tawm xov xwm yog qhov kev xaiv tsim nyog. Yog tias koj tab tom siv lub network tshiab lossis nthuav dav IP infrastructure, IPTV headend raug pom zoo. Qee qhov chaw siv ob lub tshuab xa tawm ntau hom channel, txawm hais tias xaiv ib qho raws li koj qhov kev teeb tsa tam sim no feem ntau siv nyiaj ntau dua.
Qhov chaw ntawm TV Channels
TV channels feem ntau yog los ntawm satellite tais diav, kav hlau txais xov hauv av, lossis cable TV muab kev sib txuas. Cov channel tseem tuaj yeem ua ke los ntawm cov kwj hauv internet, IP koob yees duab, khoos phis tawj, lossis lwm yam khoom siv txuas nrog.
