Izindlela Zamanje Zokudlulisa Amavidiyo E-8K Ngezixhumi Ezixhumanayo Ze-12G-SDI
Ukudluliswa kwevidiyo engu-8K (isisombululo esingu-7680×4320 noma esingu-8192×4320) ngokuxhumeka kwe-12G-SDI kuveza izithiyo ezinkulu zobuchwepheshe ngenxa yezidingo zayo eziphezulu ze-bandwidth yedatha (cishe ama-Gbps angu-48 kumasignali angu-10-bit angu-8K/60p angacindezelwanga angu-4:2:2). Ukuze kuxazululwe lokhu, abantu bathuthukise indlela esebenzisa amakhono e-12G-SDI.
Ukudluliselwa kwe-Quad-Link 12G-SDI
Indlela eyamukelwa kabanzi ukuhlukanisa isignali ye-8K ibe izithombe ezine ezincane ze-4K, isithombe ngasinye sidluliselwa ngesixhumanisi esihlukile se-12G-SDI. Futhi le ndlela ihambisana ne-SMPTE ST 2082-12 standard, echaza inqubo ye-"2-Sample Interleave" (2SI). Lapha, ividiyo ye-8K ihlukaniswe ngama-quadrant amane, ngayinye icutshungulwa njengokusakaza kwe-4K futhi idluliselwa ngezintambo ze-12G-SDI ngazinye. Ekugcineni kokwamukela, lezi zithombe ezincane ziyavumelaniswa futhi zihlanganiswe kabusha kusisombululo esigcwele se-8K. Ngakho-ke, le ndlela iqinisekisa ukuthi isignali ye-8K ihambisana kahle nemishini ekhona ye-4K ngenkathi igcina ikhwalithi yesignali.
Izinselele Neziqondiso Zesikhathi Esizayo
Nakuba ukudluliswa kwe-quad-link kusalokhu kuyindinganiso yemboni yemisebenzi yokusebenza engacindezelwanga, njengoba ukukhiqizwa kwe-8K kukhula, intuthuko ekucutshungulweni kwesignali okusekelwe ku-FPGA kanye nokwenza ngcono i-bandwidth okuqhutshwa yi-AI kulindeleke ukuthi kudlale indima ebalulekile ekunqobeni imikhawulo yamanje.
Ngamafuphi, i-12G-SDI inikeza ukudluliselwa kwe-8K ngenhlanganisela yokwahlukaniswa kwezixhumanisi eziningi, okulinganisela ukuthembeka okuphezulu nezidingo zokusetshenziswa ezisebenzayo.
