I-COFDM Modulator Demodulator Module Encoder Decoder HDMI CVBS AV Input AES 256 Ukusakaza kwe-FHD RF

Omunye umbono oseceleni

COFDM Encoder module, CVBS / kwe-HDMI, IP okukhiphayo

Ukuze uthole imininingwane eyengeziwe mayelana nebhodi yesifaki khodi se-COFDM, ngicela uvakashele lapha

I-COFDM Encoder module Inzuzo:

• Ukubambezeleka okuphansi kakhulu okungu-H.265/H.264 okulalelwayo nokufakwa kwekhodi kwevidiyo okuphezulu kusekela 1080P@60 ukuthwebula nombhalo wevidiyo wesikhathi sangempela
• Okokufaka komsindo nevidiyo kwe-HDMI noma kwe-AV, ngemva kokufaka ikhodi, okukhiphayo kwembobo ye-Ethernet noma Okuphumayo kumojula engenantambo, isilinganiso sebhithi yombhalo wekhodi yevidiyo singalungiselelwa ngamandla
• Sekela okokufaka komsindo kanye bunelayisensi okukhipha
• Sekela amavidiyo amabili (I-HDMI + AV) ukufaka ikhodi ngasikhathi sinye (option, okuzenzakalelayo kuwumbhalo wekhodi we-HDMI noma we-AV, khetha okukodwa kokubili kokufakwayo). )
• I-Web UI noma serial port UART AT umyalo yokuphathwa kokucushwa

Inguqulo yokugcina yebhodi le-TX RX

TX: I-V6.5.6p

RX: 4.1.2p

1. What should I do when I found one Tx module doesn't generate RF output power?

1. umbuzo 1: Ngicela ungitshele ingxenye yenombolo yale ngxenye, sizama ukuthola indawo futhi sihlole. impendulo 1: I-inductance ebizwa nge-LOH32PN2R2NNC.

1. Phakamisa Amaphoyinti Wokuhlola: Uma amandla amanje ebhodi esebenza kahle kodwa akukho okukhiphayo kwe-RF, mhlawumbe ingxenye engezansi I-TC1-1-13MX+ ngokuvamile ilimele.
2. Ukuze ugweme ukulimala kule divayisi ngesikhathi sokuthutha (idivayisi ngokwayo iphakeme ngokuqhathaniswa), si-ode ukuvikelwa kweglue ebomvu kule divayisi lapho siyithumela.

1. Unjiniyela uphinde aphakamise ukuthi uhlole ukuze ubone ukuthi ikhebula alixhumekile yini noma alixhumene kahle.
2. Sicela uzame ukushintsha ikhebula le-FPC elixhuma amabhodi amabili
3. We can provide spare parts if you're sure which one.

2. Ungakwazi ukunginika ifayela lomyalo le-UART AT lale modeli?

3. Lesi sidlulisi Sevidiyo ye-COFDM nomamukeli siyisekela kanjani ikhamera ye-IP?

1. Akulula ukuxhuma ku-IPC ukuze uthole a isixhumanisi sendlela eyodwa ye-COFDM. Sinemodeli ye-H264, exhunywe kokokufaka kwe-IPC ngokwandisa imbobo yenethiwekhi, kodwa kunezidingo zamamodeli e-IPC (akuwona wonke amamodeli we-IPC angaxhunywa kahle nezixhumanisi ze-COFDM), sihlole ama-IPC we I-Hikvision, I-Dahua, futhi Xiongmai, futhi uthole ukuthi umphumela wokuxhumana we I-Hikvision ikahle impela.

2. Akunakwenzeka ukususa ngokuqondile Isifaki khodi se-HDMI CVBS bese uxhuma Ikhamera ye-IP ebhodini Lokudlulisa i-COFDM. Ukuxhumeka kwendlela eyodwa ye-COFDM ku-IPC kudinga izindlela zobuchwepheshe ezikhethekile ukuze kuqalwe.

3. Indlela engcono kakhulu ukuncoma ukusebenzisa i-transceiver yethu yokudlulisa izithombe yezindlela ezimbili, esekela ngokuqondile ikhamera ye-IP.

4. Uma ikhasimende kufanele lisebenzise ibhodi yesidluliseli se-COFDM ukuze lisekele ikhamera ye-IP, kunamaphuzu amabili okufanele uwanake.

5. Iphuzu lokuqala liyinkinga yezobuchwepheshe. Kudingeka sisebenzise enye indlela ukuze sivumele izixhumanisi ze-COFDM ezingaqondile ukuthi zisetshenziswe ne-IPC.

6.Uma ucabangela i-IPC ngokombono wokunciphisa izindleko, you don't need to consider it. Ngoba ibhodi lombhalo wekhodi nebhodi lokukhipha amakhodi kusadingeka, izindleko azinakugcinwa.

7. The second point is the customer's usage habit, okungaseyona indlela yendabuko yokuxhumanisa izindlela ezimbili. Bangakwazi ukubuka i-IP Camera Video futhi balawule i-PTZ ye-IP Camera ngekhasi lewebhu noma i-PC-side PC software. (Imiyalo ye-UART AT).

8. Ngenxa yalesi sixhumanisi esingenantambo siyi-COFDM isixhumanisi sendlela eyodwa; ayikho idatha ehlehlayo (ukudluliswa kwendlela eyodwa kuphela; idatha ayikwazi ukudluliselwa isuka kumamukeli iye kumthumeli); the customer can only watch the video of the IP Camera and cannot reversely configure the IP Camera's parameters or control the PTZ of the IPCamera.

9. Lena inkinga amakhasimende amaningi angazange ayinake ekuqaleni futhi kamuva akhala ngayo ngemva kokuyisebenzisa.

10. So we don't recommend that the client choose a one-way COFDM transmitter and receiver for the IP camera. Sinesixazululo esingcono sekhamera ye-IP nge ama-transceivers amabili wesixhumanisi sevidiyo.

4. Ngicela unginikeze i-C/N Edingekayo (BER=2x10-4 ngemva kwe-Viterbi) kuma-bandwidths ahlukene 2, 4, 6, futhi 8 I-Mhz yesixhumanisi sevidiyo ye-HDMI esiyisebenzisayo?

1. Okwamanje, umamukeli unikeza kuphela amapharamitha amabili wamandla esignali kanye nezinga lephutha elincane, futhi ayikho ipharamitha ye-C/N

2. Imaphi amapharamitha okudingeka uwalungise ngokuya ngama-bandwidths ahlukene? Uma kuwukusakazwa kwekhodi yevidiyo, ibhodi lombhalo wekhodi womdluliseli ngokwalo lizobala ngokuzenzakalelayo isilinganiso sekhodi yokusakaza ividiyo efanele ngokuya ngamapharamitha asetshenziswa angenawaya njengamanje (komkhawulokudonsa, GI, CR, njll), futhi izinga lekhodi yevidiyo lizotholakala ngemva kokushintsha umkhawulokudonsa ngebhodi lepharamitha lizozivumelanisa ngokuzenzakalelayo.

3. umbuzo, Uma ikhwalithi yethu yekhamera iyinhle ngokwanele kukho kokubili 4 MHz kanye 8 MHz komkhawulokudonsa. Esimweni esinjalo, Kufanele ikhasimende likhethe 4 MHz noma 8 MHz?

impendulo: Ukuthunyelwa kwethu kwendlela eyodwa ye-COFDM kusebenzisa umkhawulokudonsa ongenantambo ongu-4Mz ngokuzenzakalelayo, ehambisana nesilinganiso sebhithi yevidiyo esingu-3.12Mbps, okwanele ku-1080p; Uma ishintshelwa kumkhawulokudonsa ongenantambo ongu-8MHz ngaphansi kwezimo ezifanayo, isilinganiso sebhithi yevidiyo siphindwe kabili kuya ku-6.24Mbps. Wonke amakhasimende angakhetha phakathi komkhawulokudonsa ongenantambo ongu-4MHz no-8MHz, ngisho ne-6MHz nayo ingacatshangelwa.

4. umbuzo: Ikuphi okungcono kule sethi ye-tx+rx ekubukeni kokuzwela kokuthola?

impendulo: Okwezixhumanisi ezingenantambo, kungacatshangwa kalula ukuthi ukuzwela okutholayo kuzoba phezulu kuma-bandwidth aphansi angenawaya. Ngokombono wokuthola ukuzwela, 4MHz>6MHz>8MHz

5. Iyiphi inguqulo ye-HDMI esezingeni okokufaka kwe-Modulator?

HDMI 1.4

6. Ingabe unawo amamojula we-COFDM Relay Repeater wesidlulisi sevidiyo esingenantambo nomamukeli?

7. Ingangithumelela isilinganiso sedatha sokuzwela kwayo 4/6/8 MHz amacala? Ngokwesibonelo, kwe-QPSK, 1/2CR, 1/32GI what threshold reception RX's input level (dBm)?

Isiteshi esisodwa esithola ukuzwela:

-97+/-1dBm ku-QPSK 8MHz,

-98+/-1dBm ku-QPSK 6MHZ,
Ukuzwela kukhuphuke ngo-3dbm lapho ithola ngezinti ezimbili

8. Ingabe le mojula isekela ngaphezu kwe-1.4G? isibonelo 2.4G, 3G, noma 3.6G?

Yebo, ukweseka.

I-COFDM Video encoder transmitter module 3.5G kanye nomphumela wokuhlola we-4G.

9. Ngingasilanda kuphi isidlali se-UDP? Sincoma i-Splayer_v4.2_2020.6.6 esiyisebenzisa njalo.

I-firmware ezenzakalelayo yomamukeli isekela isidlali se-RTSP, amanye amaklayenti akhetha isidlali se-UDP, nathi esinganikela ngakho, then RTSP player doesn't support. (I-RTSP ne-UDP ingakhetha eyodwa kwezimbili ze-firmware)

10. Ungakwazi ukunikeza ibhokisi lensimbi ukuze uvikele ibhodi lomamukeli we-COFDM?

Impela, sicela uhlole isithombe esingezansi.

11. Iyiphi ivolumu yekhadi le-MicroSD eyenza ibhodi lomamukeli?

Kuphendula unjiniyela <=128GB ngefomethi ye-FAT32 kuphela. Okubaluleke kakhulu ukuthi ukwahlukanisa okuyisisekelo kufanele kube ngefomethi ye-fat32.

I-SDI+AHD+CVBS Isifaki khodi Sevidiyo kanye nesikhiphi sekhodi se-H264 H265

Amanye amaklayenti futhi adinga i-SDI AHD CVBS isishumeki sevidiyo semodulator yesikhiphi sevidiyo esamukeli sedemodulator se-HDMI. Siphinde sibe nenye imodeli i-Vcan1776-SDI+AHD+CVBS esekela le misebenzi.

Iliphi ibhodi lesikhiphi sevidiyo elisekela i-H264 H265 kanye nokubambezeleka okuphansi kakhulu?
