Kwa nthawi yaitali, chizindikiro cha kanema cha SDI chakhala maziko a makina oulutsira nkhani aukadaulo. Pansipa pali kusanthula kwa ubwino wake mumakampani oulutsira nkhani.

Kutumiza Kwa Nthawi Yeniyeni ndi Kopanda Kutayika

SDI idapangidwa kuti igwiritsidwe ntchito potumiza chizindikiro cha baseband popanda kupsinjika, kuonetsetsa kuti palibe kuchedwa (kuchedwa kwa microsecond). Izi zimapangitsa kuti ikhale yoyenera kuwulutsa pompopompo, komwe kumafuna kulumikizana kolondola kwa nthawi.

Kudalirika Kwambiri ndi Kukhazikika

Monga muyezo wakale wa zaka makumi ambiri, zida za SDI (monga zingwe, ma rauta) zimayesedwa mwamphamvu komanso zimayikidwa muyezo. Malumikizidwe ake enieni amalimbana ndi kusokonezedwa ndi ma elekitiromagineti, zomwe zimapangitsa kuti zikhale zokhazikika m'malo ovuta owulutsira.

Kugwirizana kwa Pulagi ndi Masewera

Ma interface a SDI amaphatikizidwa padziko lonse lapansi mu zida zowulutsira (makamera, ma switcher, ma monitor), zomwe zimathandiza kulumikizana bwino popanda kukambirana za protocol. Thandizo la mawu ophatikizidwa limapangitsa kuti kutumiza ma signal kukhale kosavuta.

SDI ikadali yamtengo wapatali chifukwa chamagwiridwe antchito, kudalirika, ndi chitetezo nthawi yeniyenimakamaka m'malo owulutsa pompopompo komanso m'malo ofunikira kwambiri. Komabe,zoletsa za bandwidth, zoletsa zakuthupi, ndi ndalama zambiriKuletsa kugwiritsa ntchito njira zogwirira ntchito za ultra-high-definition (UHD). Ngakhale miyezo yatsopano monga 12G-SDI ikulimbana ndi mavuto ena, makampaniwa akufunafuna njira zosiyanasiyana kuti agwirizane ndi mphamvu za SDI ndi zosowa zaukadaulo zomwe zikubwera.
