Iindlela zangoku zokusasazwa kwevidiyo ye-8K nge-12G-SDI Interfaces

Ukuhanjiswa kwevidiyo ye-8K (isisombululo se-7680×4320 okanye i-8192×4320) ngaphezulu koqhagamshelo lwe-12G-SDI kuzisa imiqobo emikhulu yobugcisa ngenxa yeemfuno zayo eziphezulu ze-bandwidth yedatha (malunga ne-48 Gbps yezibonakaliso ze-10-bit ze-8K/60p ezingacinezelwanga). Ukusombulula oku, abantu baye baphuhlisa indlela esebenzisa amandla e-12G-SDI.

Uthumelo lwe-Quad-Link 12G-SDI

Eyona ndlela isetyenziswa kakhulu kukwahlula isignali ye-8K ibe yimifanekiso emincinci ye-4K, umfanekiso ngamnye udluliselwa ngekhonkco elahlukileyo le-12G-SDI. Kwaye le ndlela ihambelana nomgangatho we-SMPTE ST 2082-12, ochaza indlela ye-"2-Sample Interleave" (2SI). Apha, ividiyo ye-8K yahlulwe yaba ngama-quadrants amane, nganye icutshungulwa njengomjelo we-4K kwaye idluliselwa ngeentambo ze-12G-SDI ngazinye. Kwicala lokwamkela, le mifanekiso incinci iyavunyelaniswa kwaye idityaniswe kwakhona kwisisombululo esipheleleyo se-8K. Ke ngoko, le ndlela iqinisekisa ukuba isignali ye-8K ihambelana kakuhle nezixhobo ezikhoyo ze-4K ngelixa igcina umgangatho wesignali.

Imingeni kunye neMigqaliselo yexesha elizayo

Nangona ukuhanjiswa kwe-quad-link kusaqhubeka kungumgangatho weshishini wemisebenzi engakhange icinezelwe, njengoko imveliso ye-8K ikhula, ukuqhubela phambili ekucwangcisweni kwesignali esekwe kwi-FPGA kunye nokwenza ngcono i-bandwidth eqhutywa yi-AI kulindeleke ukuba kudlale indima ebalulekileyo ekoyiseni imida yangoku.

Ngamafutshane, i-12G-SDI ibonelela ngothumelo lwe-8K ngokudibanisa ulwahlulo lweekhonkco ezininzi, ilungelelanisa ukuthembeka okuphezulu neemfuno zokuphunyezwa okusebenzayo.
