Umahluko phakathi kwe-HDMI kunye ne-DisplayPort

2021-04-06

Inkqubo ye-Uqhagamshelwano lwetshiphu emsebenziCnakokwayeUmboniso wePort CnakoQhuba kwisakhiwo esinye esisiseko kunye nokwahlula-hlula okubini okudibeneyo, kwaye zombini zisebenzisa isantya esiphezulu kunye neempawu ezisezantsi zevolthi yokuhambisa idatha, kodwa kuphela kokufana phakathi kwezi zimbini.

 

Nangona le migangatho mibini ifana kakhulu ngenkangeleko, kukho umahluko omkhulu kulwakhiwo. Lo mahluko umisela ukusebenza kwekhonkco kunye neendleko, ukuhambelana, ukomelela kunye nokwenza lula ukwenziwa.

 

Inkqubo ye-Uqhagamshelwano lwetshiphu emsebenzicnakos standard now defines four connectors, A to D. Except for Type B, the rest are 19 pins. Type C and D are aimed at portnako applications and small-volume devices. Inkqubo ye-cnakos used by the two standards are slightly different.

 

Uqhagamshelwano lwetshiphu emsebenzicnakos 1.0 to 1.3 use 4 shielded coaxial differential pairs, 4 single-ended control signals, power (+5V) and ground wires. Uqhagamshelwano lwetshiphu emsebenzicnakos1.4 yongeza ishaneli yokubuyisa iaudiyo kunye nesitishi se-Ethernet, ke ukwakheka kwesiginali kwahlukile. I-HDMI1.4 isebenzisa izibini ezi-4 zokudibanisa, i-1 engalinganiyo, i-3 imiqondiso yokuphela, ukunikezelwa kwamandla (+ 5V) kunye nomhlaba.

This means that Uqhagamshelwano lwetshiphu emsebenzidata cnako 1.4 and Uqhagamshelwano lwetshiphu emsebenzidata cnako 1.3 use different cnakos. If a non-HDMI1.4 cnako 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.

Umboniso wePort defines two types of connectors, Full Size and Mini. Both connectors have 20 pins, but the width of the mini connector is about half of the full size, and their dimensions are 7.5mm x 4.5mm and 16mm x 4.8mm, respectively. To establish a complete link requires 5 coaxial pairs, 3 single-ended signals, and power and ground wires.

 

Ujongano lwe-Mini DP

 

Inkqubo ye-scalability of Umboniso wePort Cnako itself allows a low-bandwidth Umboniso wePort link to be established with fewer wires, but few people do this because it may cause confusing compatibility issues for end users.

Inkqubo ye-above is the difference between the Uqhagamshelwano lwetshiphu emsebenzihigh-definition cnako signal and the Umboniso wePort cnako signal introduced by the technical staff of Edson. Although the Uqhagamshelwano lwetshiphu emsebenzidata cnako and Umboniso wePort seem to have the same function, they are also high-speed digital serial links, but in terms of structure, they It's completely different.
