Ma'aunin DisplayPort 1.4 ya fito bisa hukuma! Yana goyan bayan 60Hz 8K bidiyo
A ranar 1 ga Maris, VESA (Ƙungiyar Ma'aunin Lantarki na Bidiyo) bisa hukuma ta sanar da sabon sigar ma'aunin watsa sauti-kayan gani na DisplayPort 1.4. Sabon ma'aunin yana ƙara haɓaka ikon watsa bidiyo da bayanai ta hanyar Nau'in-C (USB C 10Gbps, 5A 100W USB Cable), yayin da ke tallafawa watsa metadata na HDR da ƙayyadaddun bayanai na sauti. Ana ɗaukar sabon ma'aunin azaman babban sabuntawa na farko bayan fitowar DisplayPort 1.3 a cikin Satumba 2014.
A lokaci guda, wannan kuma shine ma'aunin DP na farko wanda ke goyan bayan fasahar DSC 1.2 (Display Stream Compression). A cikin sigar DSC 1.2, 3:1 za a iya ba da izinin matsawa rafin bidiyo mara asara.
"Hanyar Alternate (Alt Mode)" da aka bayar ta hanyar DP 1.3 misali ya riga ya goyi bayan watsa shirye-shiryen bidiyo na lokaci guda da rafukan bayanai ta hanyar USB Type-C da Thunderbolt musaya. Yayin da DP 1.4 ya ɗauki mataki na gaba, yana ba da izinin watsawa lokaci guda na babban ma'anar bidiyo yayin da ake amfani da SuperUSB (USB 3.0) don watsa bayanai.
Bugu da kari, DP 1.4 zai goyi bayan 60Hz 8K ƙuduri (7680 x 4320) HDR bidiyo da kuma 120Hz 4K HDR bidiyo.
Sauran sabuntawa na DP 1.4 sune kamar haka:
1. Gyara Kuskuren Gaba (FEC): Wani ɓangare na fasahar DSC 1.2, yana magance rashin haƙuri da ya dace lokacin damfara bidiyo don fitarwa zuwa nunin waje.
2. HDR Metadata Transmission: Ta amfani da "fakitin bayanai na biyu" a cikin ma'auni na DP, yana ba da goyon baya ga ma'auni na CTA 861.3 na yanzu, wanda ke da matukar amfani ga yarjejeniyar DP-HDMI 2.0a ta canza. Bugu da ƙari, yana ba da ƙarin sassauƙan watsa fakitin metadata, yana tallafawa HDR mai ƙarfi na gaba.
