HUAIN 4K High-Definition Video Conference Terminal HY-RV890H

Imathandizira Tencent Meeting ROOMS ndi Xiaowei Meeting, ma SIP ndi H.323 protocols okhazikika, ndipo imagwirizana ndi ma terminals odziwika bwino komanso zida za netiweki m'makampani.

2. Imathandizira miyezo yaposachedwa ya H.264 HP H.265, yomwe imatha kusunga bandwidth pafupifupi 50% poyerekeza ndi mibadwo yakale ya miyezo yokakamiza;

3. Imathandizira njira zingapo zopezera maikolofoni, kupereka mayankho atatu olowera mawu: maikolofoni a digito, maikolofoni a USB, ndi maikolofoni a analogi, kuti agwirizane ndi zochitika zosiyanasiyana zamisonkhano.

4. Imathandizira chitetezo cha maukonde chapamwamba kwambiri, ukadaulo wa H.460 firewall traversal, kuti ithetse kulumikizana kotetezeka pakati pa maukonde a anthu onse ndi achinsinsi;

5. Imathandizira H.235, SRTP protocol ndi AES-128 ndi ma algorithms ena obisa kuti atsimikizire chitetezo cha kulumikizana kwathunthu;

6. Imathandizira njira ziwiri za 4K full HD, zolowetsa ziwiri za HDMI high-definition, ndi zotulutsa ziwiri za HDMI high-definition.

7. API yotseguka kwathunthu, yothandizira kupanga mapulogalamu a chipani chachitatu, zomwe zimapangitsa kuti makasitomala azitha kuchita bwino ntchito zina kuti akwaniritse zofunikira zomwe akufuna.

8. Imathandizira kutumiza kwa infrared transmission. Cholumikizirachi chimatha kulandira zizindikiro za infrared kudzera pa doko lotsatizana. Mukagwiritsa ntchito kamera yosankhidwa, zizindikiro zowongolera kutali za infrared zimatha kulandiridwa kudzera pa kamera. Ngakhale cholumikizira cha conference terminal chikabisika kumbuyo, chimathabe kukwaniritsa zofunikira zowongolera za ma terminal onse.

9. Imathandizira ntchito yojambulira ndi kuulutsa patali, ndipo pamafunika PC imodzi yokha kuti ikwaniritse ntchito yojambulira ndi kuulutsa misonkhano. Imathandizira kujambula, kulumikiza ndi kusewera ma disk osungira USB, komanso kuonetsetsa kuti zolemba za misonkhano zili ndi chitetezo ndi chinsinsi.

10. Msonkhano wa kanema wa MCU1+8 (optional License) wopangidwa mwapadera, womwe ndi woyenera kwambiri pa zosowa zotsika mtengo komanso zosavuta za mabizinesi ang'onoang'ono ndi apakatikati pa msonkhano wa kanema.

11. Imathandizira kutumiza mawu a zilankhulo ziwiri nthawi imodzi. Cholumikizira sichimangothandiza kulowetsa mawu nthawi imodzi m'zilankhulo ziwiri zosiyana komanso kutulutsa mawu nthawi imodzi m'zilankhulo ziwiri zosiyana, komanso chimathandizira kusakaniza ndi kulemba mawu m'zilankhulo ziwirizi mosinthasintha.

12. Ili ndi mphamvu yolimbana ndi kutayika kwa mapaketi mwamphamvu kwambiri. Pankhani ya kutayika kwakukulu kwa mapaketi a netiweki, ukadaulo wa FEC ukhoza kuyatsidwa. Kutayika kwa mapaketi mpaka 20% sikukhudza dongosololi, ndipo misonkhano ikhoza kupitilirabe mwachizolowezi ndi kutayika kwa mapaketi kwa 30%.
