I-FMUSER DTV4660D Isiteshi se-Analog/Digital TV Channel Converter ye-TV Relay Station

Kungani i-coverter yesiteshi se-TV ibalulekile?

Isiguquli sesiteshi se-TV sohlobo lwe-rack sibalulekile ngoba sivumela umsebenzisi ukuthi athathe isignali ye-analog futhi ayiguqulele kudijithali, noma okuphambene nalokho. Lokhu kungasetshenziswa ukuze kuqinisekiswe ukuhambisana nezinhlobo ezahlukene zamadivayisi noma ukufinyelela okuqukethwe okutholakala ngefomethi eyodwa kuphela.

Iziguquli zeziteshi ze-TV zisetshenziswa kakhulu kwezokusakaza, amanethiwekhi e-cable TV, i-digital terrestrial TV, i-IPTV, ne-satellite TV. Zibuye zisetshenziswe ezinhlelweni ezinjengokusakazwa kwedatha, ukukhiqizwa komsindo/ividiyo, kanye nezithombe zezokwelapha.

Lapho uthenga isiguquli sesiteshi se-TV, kubalulekile ukucabangela ukuhambisana kohlobo lwesiginali, amandla esignali, amandla okucubungula isignali, ukusethwa kalula nokufaka, kanye nezindleko.

Gcwalisa Isixazululo Sokuguqula Isiteshi se-TV esivela ku-FMUSER

The FMUSER DTV-4660D I-analog/digital TV isiteshi iprosesa is a ehlukahlukene isixazululo ngoba ukuguqula or processing up kuya 6 iziteshi of imvamisa. It is ehambisanayo nge kokubili I-analog futhi digital amasignali, okubala DVB-C/T, ATSC, ISDB-T, futhi Okuningi, futhi izisekelo 8M or 6M isiteshi bandwidth ngoba ungeze Ukuguquguquka. Lokhu kwenza it an ekahle ukukhetha ngoba izicelo lapho amaningi amasignali kudingeka kuya be kusetshenzwe or eguquliwe.

The Okukhiphayo Izinga is ≥57dB ngoba single iziteshi, futhi ≥54dB ngoba 6 iziteshi, ukuqinisekisa ethembekile futhi high-izinga amasignali. The DTV-4660D futhi izisekelo -25~-2 dBm Okukhiphayo Izinga nge a 0.5 dBm isinyathelo, ukuhlinzeka okuqondile isilawuli phezu isignali amazinga. It is Kufanelekile ngoba Cable digital TV eduze imvamisa front-ekupheleni uhlelo, ihhotela IPTV Inethiwekhi TV uhlelo futhi ihhotela satellite digital TV uhlelo.

The DTV-4660D is kulula kuya ukusetshenziswa futhi lungisa, nge web ukuphathwa futhi kulula izibuyekezo nge web. Lokhu kuvumela abasebenzisi kuya ngokushesha futhi kalula ngokwezifiso the idivayisi kuya ukuhlangabezana zabo ethize izidingo.

The idivayisi's Ithuthukile izici futhi lula of ukusetshenziswa ukwenza it an omuhle ukukhetha ngoba kokubili fixed futhi mobile izicelo, ukuhlinzeka abathengi nge a ethembekile futhi nezimo isixazululo ngoba ukuguqula or processing amaningi iziteshi of imvamisa.

Ungasikhetha Kanjani Isiguquli Sesiteshi Se-TV Esingcono Kakhulu?

Isinyathelo 1: Cabangela ibhajethi yakho. Iziguquli zeziteshi ze-analog/idijithali ze-TV zohlobo lwe-rack zingahluka ngentengo ukusuka cishe ku-$50 ukuya kumadola angamakhulu ambalwa, kuye ngezici zazo.

Isinyathelo sesi-2: Bheka isiguquli esinezici ezifanele. Qiniseka ukuthi isiguquli sinokuphuma okudingayo, okufana ne-HDMI, i-coaxial, kanye/noma inhlanganisela. Futhi bheka okokufaka nokukhishwayo kwe-RF, futhi uqinisekise ukuthi isiguquli singakwazi ukuguqula kokubili amasignali edijithali nawe-analog.

Isinyathelo sesi-3: Khetha isiguquli esinosayizi olungile. Iziguquli zeziteshi ze-analog/idijithali ze-TV zohlobo lwe-rack zitholakala ngosayizi abahlukene, neziguquli ezinkulu ezinikeza okokufaka nokuphumayo okwengeziwe. Cabangela ukuthi mangaki okokufaka nokuphumayo okudingayo bese ukhetha isiguquli esizongena endaweni yakho yokubeka.

Isinyathelo sesi-4: Hlola ukuhambisana. Ngaphambi kokuthenga, qiniseka ukuthi isiguquli siyahambisana ne-TV yakho, ibhokisi lekhebula, noma amanye amadivaysi.

Yiziphi izinto ezidingekayo ukuze kwakhiwe isiteshi somsakazo we-TV?

Ukuze wakhe isiteshi sokudlulisa i-TV esiphelele, uzodinga izinto zokusebenza ezilandelayo:

• Isiguquli sesiteshi se-TV sohlobo lwe-Rack
• I-antenna yethelevishini
• Isikhulisi sesignali sikamabonakude
• Isihlanganisi sefrikhwensi yomsakazo (RF).
• Umthumeli
• Isamukeli sevidiyo
• Isihlungi se-RF
• Isifaki khodi se-ModulatorVideo

Ngokungeziwe kulesi sisetshenziswa, uzodinga ukuthi ufake isicelo samalayisense afanelekile ku-FCC nanoma yiziphi ezinye izinhlaka ezisebenzayo. Uzodinga futhi ukuqasha abasebenzi abanamakhono obuchwepheshe ukufaka nokugcina okokusebenza.
