Fiiro gaar ah

Marka gudbiyaha COFDM-905T iyo qaataha COFDM-905T ay sameeyaan nidaamka gudbinta fiidyaha wireless-ka dhibic-ilaa-bar, Tilmaamaha daahitaanka fiidiyowga:
Saddexda tilmaame ee daahitaanka muuqaalka, heerka yara video, iyo heerka isdhexgalka hawadu waa saamaynta labada dhinac iyo xakamaynta labada dhinac. Marka heerka is dhexgalka hawadu ka weyn yahay 5 jeer heerka code video, daahitaanka muuqaalku waa ugu yaraan. Kiiskan, imtixaanka dhabta ah waa in daahitaanka video ku saabsan yahay 60 ms marka koodka lagu gudbiyo 720P@60, daahitaanka muuqaalkuna wuxuu ku saabsan yahay 130 ms at 1080P@60. Daahitaanka waxaa loola jeedaa daahitaanka ka yimid gelinta fiidyowga HDMI ee dhamaadka gudbinta ee soosaarka fiidyowga HDMI ee dhamaadka helitaanka, marka laga reebo daahitaanka kamarada hore ee dhamaadka gudbinta (waxaanu qiyaasnay ​​daahitaanka kamarada SLR ee sumadda 70 ms, iyo daahitaanka camera sports brand caan ah oo ku saabsan 130 ms). Inta badan xaaladaha codsiga, daahitaanka muqaalka waxa loo dejiyay ilaa 200ms sida caadiga ah.

Marka gudbiyaha COFDM-905T iyo qaataha COFDM-905R ay sameeyaan nidaamka gudbinta fiidyaha wireless-ka dhibic-ilaa-bar, fogaanta gudbinta waa:
Fogaanta gudbinta wirelessku waxay la xiriirtaa arrimo badan sida deegaanka tijaabada, faragelinta korantada ambient, xaaladaha xidhitaan, qoyaan hawada, inta jeer ee shaqada, bandwidth wireless, iyo gudbinta iyo helitaanka anteenooyinka. Natiijooyinka imtixaanka dhabta ah: imtixaanka macmiilka, diyaarad aan duuliye lahayn ayaa ku rakibtay gudbiyaha ST100 si ay ugu duusho 100 mitir sare, loo dhigay 4M QPSK wiwidhwidhsiidh wireless, 700Inta jeer ee hawlgalka xarunta MHz, 1W gudbiya awooda, anteeno gudbiyaha 3dBi agagaarka, Helitaanka faa'iido anteeno fiber laba galaas ah oo ku saabsan 10dBi, masaafo dhan ilaa 16km (video siman); imtixaanka wadada noo gaar ah ee Shenzhen, daah-furka dhamaadka duulista, anteenada tuubada caadiga ah (ku saabsan 3dBi faa'iido), 340MHz bilaabay, QPSK 8M Bandballth, anteeno fiberglass ah oo ku taal dhamaadka helitaanka, iyo anteenada Yagi, ku saabsan 2.2 mitir sare oo tiirka ah, 2.2 kiiloomitir u jira, muuqaal sare oo siman, tiro yar oo dhismayaal dhaadheer ah oo u dhexeeya gudbiyaha iyo soo-qaadaha, wadada muuqaal ahaan ku saabsan 20 foorarsi darajo. Sababo la xiriira xannibaado shuruudaysan, tijaabo kale oo waddo ah lama samayn.
