I-Multi-channel digital video optical transceivers ingaba nemisebenzi emininzi, kwaye uhlobo ngalunye lomsebenzi luneemfuno zenkcazo yezobugcisa ezihambelanayo, ezifana nesalathisi sevidiyo, i-audio index, i-asynchronous data index, i-Ethernet index, isalathisi sefowuni kunye nokunye. Iimpawu zobugcisa ezikhethekileyo zinokufuna ukuba umenzi abonelele ngesatifikethi sovavanyo lomntu wesithathu, kwaye iinjineli eziqeqeshiweyo kufuneka ziphinde ziphinde ziphinde ziphinde ziphinde ziphinde ziphinde ziphinde ziphinde ziphinde ziphinde zilandelelene nezalathi ezibonelelwe ngumenzi phambi kokuthenga izixhobo zokujonga ezona mpawu zobugcisa zesixhobo kunye nokuthembeka komenzi. Apha kugxininise ekuchazeni ngokufutshane ezi zalathisi zimbini zilandelayo zevidiyo ukusuka kumbono wobunjineli.

I-bandwidth yevidiyo yenye yezona zinto zikhankanywa rhoqo. I-bandwidth yevidiyo enganeleyo, iinkcukacha zesikrini sokubeka iliso azicacanga ngokwaneleyo, isisombululo esithe tye siphantsi, kunye nokuphazamiseka kombala okunzulu okanye ukulahleka kwevidiyo kwenzeka. Kuchanekileyo ngenxa yokubaluleka kwe-bandwidth yevidiyo kumgangatho wesithombe ukuba abanye abavelisi abanganyanisekanga bawabaxa ngamabomu umda wevidiyo yeemveliso zabo ukukhohlisa abathengi. Ngokomzekelo, i-transceiver yedijithali yevidiyo eveliswa ngumenzi othile ithi i-bandwidth yayo yevidiyo yi-8M, kodwa i-frequency ye-sampling yevidiyo ebhengezwe esidlangalaleni yi-12.5M. Ngokomthetho we-sampling yeNyquist, ukubuyisela ngokwenene umqondiso, i-sampling frequency yayo kufuneka ibe ubuncinane kabini i-signal frequency , ibalwa ngolu hlobo, i-bandwidth yevidiyo yethiyori yale transceiver ebonakalayo yomenzi ayikwazi ukudlula i-6.25M kuyo nayiphi na imeko. Kwiinkampani zobunjineli ngokubanzi kunye nabasebenzisi ngokujonga iinkcukacha zomfanekiso, banokugweba ngokungqongqo umda wevidiyo wesixhobo.

I-APL yinqanaba lomfanekiso ophakathi, kwaye iinkampani ezininzi zobunjineli azinikeli ngqalelo enkulu okanye aziqhelananga nesi salathisi. Nangona kunjalo, ukuba sithetha ngengxaki efunyenwe kwezinye iiprojekthi: isignali yevidiyo idluliselwa nge-transceiver optical, xa kukho indawo enkulu emhlophe emfanekisweni (njengaxa ikhamera ikhanyiswa kukukhanya okunamandla), umfanekiso uvuliwe. imonitha iya kugungqa ngokuthe tye, ngoko ke Abasebenzi bobunjineli kufuneka bangabi ngabantu abangaziwayo. Oku kungenxa yokuba uluhlu lwe-APL lwee-transceivers ezibonakalayo zevidiyo eziveliswe ngabavelisi abathile zimxinwa kakhulu. Xa kukho indawo enkulu emhlophe kwisignali yomfanekiso, icandelo le-DC kumgca ngamnye wesiginali yomfanekiso liyenyuka, kwaye i-APL iya kwanda, okubangela ukuhla kwe-amplitude yesignali yokuvumelanisa ethe tye. Okanye ilahlekile, imonitha ayikwazi ukubona ungqamaniso lomgca kwaye isikrini siyashukuma.
