Umehluko phakathi kwe-HDMI ne-DisplayPort

2021-04-06

I-I-HDMICuyakwazifuthiI-DisplayPort Cuyakwazizisebenza ngesakhiwo esifanayo esiyisisekelo nokwahlukana kokubhangqa okusontekile kwe-coaxial, futhi zombili zisebenzisa amasiginali wejubane eliphezulu nowe-low voltage ukuhambisa idatha, kepha yilokho kuphela ukufana phakathi kwalokhu okubili.

 

Yize izindinganiso ezimbili zifana kakhulu ngokubukeka, kunomehluko omkhulu esakhiweni. Lo mehluko unquma ukusebenza kwesixhumanisi nezindleko zaso, ukuhambisana, ukuqina, kanye nokwenza lula ukusebenza.

 

I-I-HDMIcuyakwazis standard now defines four connectors, A to D. Except for Type B, the rest are 19 pins. Type C and D are aimed at portuyakwazi applications and small-volume devices. I-cuyakwazis used by the two standards are slightly different.

 

I-HDMIcuyakwazis 1.0 to 1.3 use 4 shielded coaxial differential pairs, 4 single-ended control signals, power (+5V) and ground wires. I-HDMIcuyakwazis1.4 ingeza isiteshi sokubuyisa umsindo nesiteshi se-Ethernet, ngakho-ke ukwakheka kwesiginali kwehlukile. I-HDMI1.4 isebenzisa ngazimbili i-coaxial 4, i-1 pair engafani, amasiginali ama-3 aphela, ukunikezwa kwamandla (+ 5V) nomhlabathi.

This means that I-HDMIdata cuyakwazi 1.4 and I-HDMIdata cuyakwazi 1.3 use different cuyakwazis. If a non-HDMI1.4 cuyakwazi is used in the HDMI1.4 system, the audio return and Ethernet functions will be lost. However, all the features of HDMI1.3 and other new features of HDMI1.4 (such as 3D) can be retained.

I-I-I-DisplayPortichaza izinhlobo ezimbili zezixhumi, Usayizi Ogcwele kanye neMini. Zombili izixhumi zinezikhonkwane ezingama-20, kepha ububanzi besixhumi esincane bucishe bube uhhafu wosayizi ogcwele, futhi ubukhulu bazo bungu-7.5mm x 4.5mm no-16mm x 4.8mm, ngokulandelana. Ukusungula isixhumanisi esiphelele kudinga ama-coaxial 5 ama-coaxial, amasiginali ama-3 aphela kanye namandla nezintambo zomhlaba.

I-scalability of I-I-DisplayPortCuyakwazi itself allows a low-bandwidth I-I-DisplayPortlink to be established with fewer wires, but few people do this because it may cause confusing compatibility issues for end users.

I-above is the difference between the I-HDMIhigh-definition cuyakwazi signal and the I-I-DisplayPortcuyakwazi signal introduced by the technical staff of Edson. Although the I-HDMIdata cuyakwazi and I-I-DisplayPortseem to have the same function, they are also high-speed digital serial links, but in terms of structure, they It's completely different.
