HUAIN 4K Lub Rooj Sib Tham Video Siab HY-RV890H

Txhawb nqa Tencent Meeting ROOMS thiab Xiaowei Meeting, tus qauv SIP thiab H.323 protocols, thiab sib xws nrog cov qauv terminals thiab network-side devices hauv kev lag luam.

2. Txhawb cov qauv encoding H.264 HP H.265 tshiab kawg, uas tuaj yeem txuag tau kwv yees li 50% bandwidth piv rau tiam dhau los ntawm cov qauv compression;

3. Nws txhawb ntau txoj kev nkag mus rau lub microphone, muab peb qhov kev daws teeb meem suab: digital microphones, USB microphones, thiab analog microphones, kom hloov kho rau ntau yam xwm txheej sib ntsib.

4. Txhawb kev ruaj ntseg hauv network ultra-high, H.460 firewall traversal technology, los daws qhov kev sib txuas ruaj ntseg ntawm cov tes hauj lwm pej xeem thiab ntiag tug;

5. Txhawb H.235, SRTP protocol thiab AES-128 thiab lwm yam encryption algorithms kom ntseeg tau tias muaj kev ruaj ntseg ntawm kev sib txuas lus;

6. Txhawb ob lub 4K puv HD channels, 2 HDMI high-definition video inputs, thiab 2 HDMI high-definition video outputs.

7. API qhib tag nrho, txhawb kev tsim cov ntawv thov thib peb, ua rau nws yooj yim rau cov neeg siv khoom los ua qhov kev txhim kho thib ob kom ua tau raws li cov kev xav tau tshwj xeeb.

8. Nws txhawb nqa kev xa xov infrared pob tshab. Lub davhlau ya nyob twg tuaj yeem txais cov teeb liab infrared los ntawm qhov chaw nres nkoj serial. Thaum ua haujlwm nrog lub koob yees duab qauv tshwj xeeb, cov teeb liab tswj chaw taws teeb infrared tuaj yeem txais los ntawm lub koob yees duab. Txawm tias lub davhlau ya nyob twg rooj sib tham zais rau tom qab, nws tseem tuaj yeem ua tau raws li qhov yuav tsum tau tswj hwm ntawm txhua lub davhlau ya nyob twg.

9. Nws txhawb nqa kev kaw suab thiab kev tshaj tawm hauv xov tooj cua, thiab tsuas yog xav tau ib lub PC xwb los ua tiav kev kaw suab thiab kev tshaj tawm hauv xov tooj cua. Txhawb nqa USB cia disk kaw suab, ntsaws thiab ua si, thiab ua kom muaj kev ruaj ntseg thiab kev ceev ntiag tug ntawm cov ntaub ntawv sib tham.

10. Xaiv tau MCU1 + 8 (Daim Ntawv Tso Cai Xaiv Tau) kev sib tham video siab, uas yog qhov tsim nyog rau cov nqi qis thiab kev xav tau yooj yim ntawm cov lag luam me thiab nruab nrab rau kev sib tham video.

11. Txhawb kev xa cov suab ob hom lus tib lub sijhawm. Lub davhlau ya nyob twg tsis yog tsuas yog txhawb nqa cov suab nkag ua ob hom lus sib txawv thiab cov suab tso tawm ua ob hom lus sib txawv, tab sis kuj txhawb nqa kev sib xyaw thiab encoding cov suab tso tawm hauv ob hom lus.

12. Nws muaj peev xwm tiv thaiv kev poob pob khoom muaj zog heev. Yog tias muaj kev poob pob khoom hauv network loj heev, cov thev naus laus zis FEC tshwj xeeb tuaj yeem ua haujlwm tau. Kev poob pob khoom txog li 20% yuav tsis cuam tshuam rau lub kaw lus, thiab cov rooj sib tham tseem tuaj yeem ua mus li qub nrog kev poob pob khoom ntawm 30%.

17. Dual-stream Protocol: ITU-T H.239, BFCP;

18. Lwm cov txheej txheem sib txuas lus: H.221, H.224, H.225, H.235, H.241, H.245, H.281, H.350, H.460, T.140, DTMF;

19. Kev Sib Txuas Lus Hauv Network: TCP/IP, DHCP, SSH, HTTP, HTTPS nrog SSL/TLS, RTP, RTCP, RFC3261, RFC3264, RFC2190, RFC3407, RFC2833, RFC4585(RTP/AVPF), SNTP, ARP;

20. Kev daws teeb meem ntawm cov duab nquag: 4KP30, qhov tsawg kawg nkaus bandwidth: 2048Kpbs;

21. Cov yam ntxwv suab: Tsis siv neeg Echo Cancellation (AEC), automatic Gain Control (AGC), automatic noise Suppression (ANS), thiab kev txhawb nqa rau lip-sync.
