Mutu wotsatira wolankhula nawo pamsonkhano wamavidiyo wakula kwambiri zaka zingapo zapitazi. Ukadaulo wapangitsa kuti zitheke kugwiritsa ntchito njira zovuta zosinthira zidziwitso zamawu / makanema munthawi yeniyeni, zomwe zidapangitsa Polycom, pafupifupi zaka 10 zapitazo, kuyambitsa njira yoyamba padziko lonse lapansi yotsata olankhula mwanzeru. Kwa zaka zingapo adakwanitsa kukhalabe eni okhawo a yankho lotere, koma Cisco sanachedwe kudikira nthawi yayitali ndikubweretsa ku msika mawonekedwe awo anzeru zamakamera awiri, omwe anali mpikisano wabwino pa yankho la Polycom. Kwa zaka zambiri, gawo ili la msonkhano wapavidiyo linali lochepa chifukwa cha kuthekera kwa angapo mwini zopangidwa, koma nkhaniyi idaperekedwa koyamba konsekonse yankho la chiwongolero cha kamera ndi mawu, chogwirizana ndi zida zonse za hardware ndi mapulogalamu a msonkhano wamakanema.
Ndisanapitirire kufotokoza mayankho ndikuwonetsa kuthekera, ndikufuna kuzindikira chochitika chofunikira:
Ndine wolemekezeka kupereka kwa gulu la Habra , yoperekedwa ku mayankho a videoconferencing (VCC). Tsopano, chifukwa cha khama logwirizana (wanga ndi UFO), ili ndi nyumba yake ku Habré, ndipo ndikupempha aliyense amene ali nawo pamutuwu komanso waposachedwa kuti alembetse .
Zochitika ziwiri zolozera kamera pa wokamba nkhani
Pakadali pano, ophatikiza mayankho pamisonkhano yamakanema amadzisankhira okha njira ziwiri zosiyana zogwirira ntchito yolunjika kwa wowonetsa:
- Automatic - Wanzeru
- Semi-automatic - yokhazikika
Njira yoyamba ndi mayankho ochokera ku Cisco, Polycom ndi opanga ena; tikambirana pansipa. Pano tikuthana ndi zodzichitira zokha zolozera kamera kwa olankhula nawo pamsonkhano wamavidiyo. Ma aligorivimu apadera pokonza ma siginecha amawu/kanema amalola kamera kusankha malo omwe akufunira palokha.
Njira yachiwiri ndi makina opangira makina otengera owongolera osiyanasiyana akunja; sitingawaganizire mwatsatanetsatane, chifukwa Nkhaniyi idaperekedwa makamaka pakutsata okamba.
Pali othandizira ochepa pazochitika zachiwiri zowonetsera makamera, ndipo pali zifukwa za izi. Ophatikiza odziwa bwino amamvetsetsa kuti mayankho anzeru ochokera ku Polycom ndi Cisco amafunikira malo abwino ogwirira ntchito kuti makina azigwira bwino ntchito. Koma sizotheka nthawi zonse kupereka zinthu zotere, chifukwa chake magwiridwe antchito nthawi zina amatsimikiziridwa ndi njira iyi yothetsera vuto lolozera kamera:
1. Zokonzekera zonse zofunika (malo a chipangizo cha PTZ ndi optical zoom factor) zimalowetsedwa pasadakhale mu kukumbukira kwa kamera (kapena nthawi zina mu wolamulira). Monga lamulo, iyi ndi dongosolo lonse la chipinda cha msonkhano, ndikuwona kwa aliyense wochita nawo msonkhano pazithunzi.
2. Kenako, oyambitsa kuyimba kofunikirako amaikidwa m'malo omwe atchulidwa - awa ndi maikolofoni otonthoza kapena mabatani a wailesi, kawirikawiri, chipangizo chilichonse chomwe chingapereke chizindikiro chowongolera chomwe chimamvetsetsa.
3. Wowongolera amapangidwa mwanjira yoti aliyense woyambitsa ali ndi preset yake. Ndondomeko yonse ya chipindacho - oyambitsa onse amazimitsidwa.
Chotsatira chake, pogwiritsira ntchito dongosolo la congress, mwachitsanzo, ndi wolamulira, wokamba nkhani asanayambe kulankhula, amatsegula maikolofoni yake. Dongosolo lowongolera nthawi yomweyo limakonza malo a kamera osungidwa.
Izi zimagwira ntchito mosalakwitsa - makinawo safunikira kuchita katatu ndi kusanthula makanema. Ndidakanikiza batani ndipo zokonzeratu zidagwira ntchito, osachedwetsa kapena zabodza.
Njira zowongolera ndi zodzichitira zimagwiritsidwa ntchito m'zipinda zazikulu, zovuta, pomwe nthawi zina palibe, koma makamera angapo amakanema amayikidwa. Chabwino, m'zipinda zazing'ono ndi zazing'ono zochitira misonkhano, makina odzipangira okha ndi abwino (ngati muli ndi bajeti).
Tiyeni tiyambe ndi oyambitsa makolo.
Mtsogoleri wa Polycom EagleEye
Yankho ili kamodzi lidapangitsa chidwi pamisonkhano yamakanema. Mtsogoleri wa Polycom EagleEye anali yankho loyamba pazaupangiri wanzeru wamakamera. Yankho lake lili ndi gawo loyambira la EagleEye Director ndi makamera awiri.
