A cikin hanyar sadarwa na tsarin sa ido na bidiyo, babban adadin ci gaba da bayanan bidiyo yana buƙatar watsawa, wanda ke buƙatar sauyawa don samun damar tura bayanai a tsaye. Da yawan kyamarori da aka haɗa zuwa maɓalli, mafi girman adadin bayanan da ke gudana ta cikin maɓalli. Za mu iya tunanin lambar yana gudana yayin da ruwa ke gudana, kuma masu sauyawa sune mahadar kiyaye ruwa ɗaya bayan ɗaya. Da zarar ruwan da ke gudana ya wuce kaya, dam din zai fashe. Hakazalika, idan adadin bayanan da kyamarar ke turawa a ƙarƙashin maɓalli ya zarce ƙarfin tura tashar jiragen ruwa, hakanan zai sa tashar ta zubar da bayanai masu yawa tare da haifar da matsala.
Misali, saurin tura bayanai na 100M wanda ya wuce 100M zai haifar da asarar fakiti masu yawa, wanda ke haifar da al'amari na blurred allo da makale.
Don haka, kyamarori nawa ne ya kamata a haɗa su zuwa canjin gigabit?
Akwai ma'auni, duba adadin bayanan da tashar tashar kyamara ta sama ta tura: idan adadin bayanan da tashar tashar ta sama ta fi 70M, zaɓi tashar gigabit, wato, zaɓi gigabit switch ko gigabit. uplink canza
Ga lissafin sauri da hanyar zaɓi:
Ƙimar bandwidth = (ƙarshen rafi + babban rafi) * adadin tashoshi * 1.2
① Darajar bandwidth>70M, yi amfani da Gigabit
② Darajar bandwidth <70M, yi amfani da 100M
Misali, idan akwai maɓalli da aka haɗa da kyamarori 20 H.264 200W (4+1M), to bisa ga wannan lissafin, ƙimar isar da tashar tashar jiragen ruwa (4+1)*20*1.2=120M>70M. A wannan yanayin, ya kamata a yi amfani da maɓalli na gigabit. A wasu al'amuran, tashar jiragen ruwa ɗaya kawai na sauyawa yana buƙatar zama gigabit, amma idan tsarin tsarin ba zai iya inganta ba kuma ana iya daidaita zirga-zirgar zirga-zirga, to ana buƙatar canjin gigabit ko gigabit uplink switch.
Tambaya 1: Tsarin lissafin rafin lambar a bayyane yake, amma me yasa aka ninka shi da 1.2?
